P wave - Primary, longitudinal, irrotational, push, pressure, dilatational, compressional, or push-pull wave. P waves are the fastest body waves and arrive at stations before the S waves, or secondary waves. The waves carry energy through the Earth as longitudinal waves, moving particles in the same line as the direction of the wave. P waves can travel through all layers of the Earth. P waves are generally felt by humans as a bang or thump. - USGS Earthquake glossary

PA - Passive Annihilation (a link on the VHEMT Links page) "Passive Annihilation is an existential form of anti-procreation. The principle goes like this: If you can't gain informed consent from a child before bringing him/her into the world, you don't have the authority to do so. It follows that NOBODY has the right to procreate. That's the nutshell; it's more intricate than that. Passive Annihilation is a cousin to VHEMT, the Voluntary Human Extinction Movement, which has a more environmental slant."

Paris Club - The Paris Club is the name govern to the ad hoc meetings of Western - creditor government that, since 1956, have arranged, when necessary, for the renegotiation of debt wowed to official creditors or guaranteed by them. (Debts to commercial banks are renegotiated with committees of the banks involved.) Neither the world Bank nor the IMF is a member of the Paris Club although the IMF has played an increasingly important role in putting together debt restructuring packages with commercial banks. To reschedule debt, both the Paris Club and commercial banks require the debtor country to have agreed on a stabilization program with the IMF. - WB
Parity-based support prices - Commodity support prices (such as loan rates or commodity program purchase prices) whose level in a given year is mandated to be calculated in a way that will maintain its purchasing power at the level it had in the 1910-14 base period. Under "permanent provisions," of farm legislation (provisions that would automatically apply in the absence of current farm acts that suspended the permanent provisions) prices of some commodities would be supported at 50 to 90 percent of parity through direct government purchases or non-recourse loans. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms
Parity Price - A measurement of the purchasing power of a unit of a particular commodity. Originally, parity was the price per bushel, bale, pound, or hundredweight that would be necessary for a unit of a commodity today to buy the same quantity of other goods (from a standard list) that the commodity could have purchased in the 1910-14 base period. Under permanent law, prices of some commodities would be supported at 50 to 90% of parity through direct government purchases or non-recourse loans. In 1948, the parity price formula was revised to make parity prices dependent on the relationship of farm and non-farm prices during the most recent 10-year period for non-basic commodities. Basic commodities, including wheat, corn, rice, peanuts, and cotton use the higher of the historical or the new formula.
Parity Ratio - An aggregate measure of the relative purchasing power of farm products; the ratio between the index of prices received by farmers for all farm products and the index of prices paid by farmers for commodities and services used in farm production and family living. The parity ratio measures relative price relationships (prices received versus prices paid). Over time the parity ratio has declined due to greater efficiency gains in agriculture. Compared to a parity ratio of 100 in the 1910-14 time period, the 1995 annual parity ratio was 45.
Park - The terms national park or park refer to any unit of the national park system. Although national park system designations formally categorize units as national parks, national preserves, national monuments, national historic sites, national historical parks, national memorials, national recreation areas, national lakeshores, national seashores, national rivers, national battlefields, or national cemeteries, all units of the national park system are managed under a single set of laws and policies with the only distinctions being special mandates included in the specific legislation applying to each particular unit.

Partial Taking - Florida Rock Industries, Inc. v. United States (U.S. Court of Appeals for the Federal Circuit 1994) The federal court of appeals saw no logical distinction between (1) a taking of private property by physical occupation for the public use as a park and (2) a regulatory imposition to preserve the property as a wetland for public uses. The case was remanded to the Court of Claims to determine how much of the value of the 98 acres had been taken by government regulation. In 1995, Oregonians In Action stated, "The decision of the U.S. Supreme Court not to review Florida Rock is a major breakthrough; the high court implies it favors paying landowner compensation for 'partial takings' by regulatory use restrictions as well as total takings."(1) "Looking Forward," Oregonians In Action.

Particulate Matter - A category of air pollutants that refers to small, solid particles or liquid droplets suspended in the air, including soot, fumes, dust, pollen and spores, smoke, and spray. Particles vary in biological effect depending on their size and composition. Two National Ambient Air Quality Standards have been set for particulates: One, in effect since 1987, regulates particles smaller than 10 microns in diameter (PM10), a size range that includes fugitive dust from construction and tilling the soil. A 1997 change in how compliance with the PM10 standard is measured somewhat reduces the stringency of the standard, which will make it easer for areas not in compliance (41 in early 1997) to attain the standard. The second PM standard, promulgated in July 1997, regulates particles smaller than 2.5 microns (PM2.5), a size range dominated by combustion products, but which can include very fine fugitive dust and ammonia that can come from agricultural sources. Because of the need to develop monitoring and assess ambient levels of PM2.5, it will be the mid-2000s before pollution levels are established and any control programs might be instituted.
Particulates - Small particles suspended in the air and generally considered pollutants.
Parting Fire - Assay procedure for separating gold from other metals.
Paratransit - Forms of public passenger transportation that can operate over the highway and street system, but without a fixed route. Examples of paratransit include shared-ride taxis, carpools, rental cars, and subscription bus clubs.

Pastoralism - A form of agricultural activity that involves the raising of livestock. Many peoples described as herders actually pursue mixed agriculture, in that they may also fish, hunt, or even grow a few crops, but pastoral peoples' lives do revolve around their animals. (UN)
Pasture - (1) Land that is separated from other areas by a fence or natural barriers. (2) The act of letting livestock graze on land for forage.
Pastureland - Land used primarily for the production of domesticated forage plants for livestock (in contrast to rangeland, where vegetation is naturally occurring and is dominated by grasses and perhaps shrubs). Rotation pasture or cropland under winter cover crops is not included in this definition. The 1992 national resources inventory recorded 126 million acres of pastureland, 9% of all nonfederal rural lands.
Pastureland - Land used primarily for the production of adapted, introduced or native species in a pure stand, grass mixture or a grass-legume mixture. Cultural treatment in the form of fertilization, weed control, reseeding or renovation is usually a part of pasture management in addition to grazing management. In 1982, 32 percent of pastureland in the United States was considered good, 40 percent fair and 19 percent poor. [source: USDA-SCS 1982 NRI] 2. A Land cover/use category of land managed primarily for the production of introduced forage plants for livestock grazing. Pastureland cover may consist of a single species in a pure stand, a grass mixture, or a grass-legume mixture. Management usually consists of cultural treatments: fertilization, weed control, reseeding or renovation, and control of grazing. For the NRI, includes land that has a vegetative cover of grasses, legumes, and/or forbs, regardless of whether or not it is being grazed by livestock. - National Resources Inventory
Pastureland and Native Pasture - A Land Cover/Use category of land managed primarily for the production of introduced or native forage plants for livestock grazing.

PAYD - Pay-As-You-Drive (car insurance) On Thursday, June 19, 2003, the Oregon Senate passed House Bill 2043, a bill designed to encourage automobile insurance companies to offer cents-per-mile premiums. The bill is now before the governor, who has not decided whether or not he will sign. Known as mileage-based or Pay-As-You-Drive (PAYD), the policies are beneficial to those persons who use their vehicles rarely. The risk of accident is substantially dependent on how long the vehicle is on the road, so those who drive less often pay more per mile under the current system. That results in a disincentive to use other means of transportation, since drivers have unlimited miles for their premium term -- the more they drive, the more they get out of their insurance policy. PAYD premiums, on the other hand, create an incentive to use alternate means of transportation, such as mass transit, bicycles, or carpooling. In addition to driver benefits, PAYD insurance will result in improved air and water quality, reduced congestion, mitigation of our impact on the climate, and resource conservation. Auto insurers are interested in offering the policies, but bear the costs of setting up the system and tracking mileage. House Bill 2043 provides the incentive to create such infrastructure through tax credits to insurance companies for PAYD policies issued.

Payment-in-Kind (PIK) - In general, a payment made in the form of Commodity Credit Corporation (CCC) -owned commodities (or title to them) in lieu of cash. This form of payment was widely used during the 1980s for paid diversion, deficiency payments, and export subsidy payments as a means of disposing of or avoiding the acquisition of commodity inventories. PIK certificates entitled the holder to specific quantity of commodities.
Payment limitation - The maximum amount of commodity program benefits a person can receive by law. "Persons," as defined by payment limitation regulations established by the Secretary of Agriculture, are individuals; members of joint operations; or entities such as limited partnerships, corporations, associations, trusts, and estates that are actively engaged in farming. The 1996 Act sets payment limits at $40,000 per person per fiscal year for payments on production flexibility contracts. The Food Security Act of 1985, as amended by the 1996 Act, established limits at $75,000 per person per crop year for the total amount received from marketing loan gains and loan deficiency payments for one or more crops of contract commodities or oilseeds, during 1996-2002. However, the agriculture budget appropriations acts for fiscal years 2000 and 2001 established a $150,000 payment limitation for the total of marketing loan gains and loan deficiency payments for the 1999 and 2000 crops of contract commodities and oilseeds (and honey for 2000 crop). - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

Peak Flow - The greatest flow attained during the melting of the winter snow pack.
Peak Period - The period of time during which the maximum amount of demand occurs. Generally, the measurement is based on a period of one hour.
Peanut poundage quota - The maximum quantity of peanuts that is eligible for the higher of two price support loan rates. The Food and Agriculture Act of 1977 (P.L. 95-113) initiated the current two-price poundage quota program for peanuts where a national poundage quota is established and each producer receives a share of the national total. Producers can market more than their quota, but only the quota amount is eligible for domestic edible use and for the higher of the two commodity loan rates. Over-quota marketings are called "additional peanuts," and can only be sold for export or processing (crush). Under the 1990 Act, each year's national peanut poundage quota was set equal to estimated domestic use of peanuts for food products and seed, subject to a minimum 1.35 million tons. The 1996 Act redefined the national poundage quota to exclude seed use and eliminated the 1.35-million-ton minimum. The 1996 Act also permits the sale, lease, and transfer of a quota across county lines within a State up to specified amounts of quota annually. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

Most decisions on the merits by the Supreme Court (and other appellate courts in the U.S.) take the form of one or more opinions signed by individual justices (and joined in by others). Even when such signed opinions are unanimous, they are not termed "per curiam." "Per curiam" decisions are given that label by the Court itself and tend to be short. Usually, though not always, they deal with issues the Court views as relatively non-controversial. For examples, see, e.g.,Wood v. Bartholomew, No. 94-1419 (Oct. 10, 1995) and Kimberlin v. Quinlin, No. 93-2068 (June 12, 1995) . However, they are not necessarily unanimous. Indeed, some per curiam decisions are accompanied by dissenting opinions. See, e.g., Bush v. Gore, No. 00-949 (December 12, 2000). The top appellate courts of most states (including, e.g., Alabama, Arkansas, Connecticut, Florida, Georgia, Maryland, Nebraska, Nevada, New Mexico, North Carolina) use the same terminology. During each Supreme Court term, the LII's Supreme Court collection includes a running list linking to per curiam decisions and other orders or actions taken without full opinion by the Court. - Supreme Court glossary

Pest Resistance Management Plans (PRM) - To protect the continued use of bio-pesticides, EPA is requiring companies developing transgenic crops to submit and implement pest resistance management (PRM) plans as a requirement of product registration. If they are exposed to a toxin excessively, most insect populations can develop resistance, making pest control products less effective. With new bio-pesticide technologies comes the concern that pests will rapidly develop resistance to natural insecticides. A resistance management plan is intended to sustain the useful life of transgenic technology.
Pest risk analysis - The process of evaluating biological or other scientific and economic evidence to determine whether a pest should be regulated and the strength of any phytosanitary measures to be taken against it. - UN/FAO International Plant Protection Convention Glossary
Pest Scouting - Inspecting a field for pests, including insects, weeds, and pathogens. Pest scouting is a basic component of integrated pest management programs. It is used to determine whether pest populations are at levels that warrant control intervention and also may help to determine the most appropriate method of control.
Pesticide User Expenditures - Dollar value of purchases by persons or businesses applying pesticides, such as farmers, commercial pesticide applicators and homeowners. Reported numbers are nominal values for the years indicated, i.e., not adjusted or indexed for inflation. - EPA Office of Pesticide Programs Glossary
Pesticides - Chemicals used to kill insects or other organisms harmful to cultivated plants or human health. Many pesticides are toxic to humans, livestock and wildlife as well as to the target pest. Ecosystems have no natural mechanism for breaking down most human-made chemicals with the result that they usually persist in the environment. Despite 40 years of extensive pesticide use, worldwide crop losses from insects have almost doubled. The FAO reports that more than 1600 insect species have developed pesticide resistance. Pesticides kill harmful insects but they also kill beneficial ones like bees. (UNESCO) A substance used to kill, control, repel, or mitigate any pest. Insecticides, fungicides, rodenticides, herbicides, and germicides are all pesticides. EPA regulates pesticides under authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). In addition, under FIFRA, a substance used as a plant regulator, defoliant, or desiccant is defined as a pesticide and regulated accordingly. All pesticides must be registered and carry a label approved by EPA.

Whenever a pesticide is registered for use on a food or a feed crop, a tolerance (or exemption from the tolerance requirement) must be established. EPA establishes the tolerance levels, which are enforced by the Food and Drug Administration and USDA.
Pesticide Usage - Refers to actual applications of pesticides, generally in terms of quantity applied or units treated. - EPA Office of Pesticide Programs Glossary

PFP - Property For Parks Program Property For Parks (PFP) Program - "Saving the Legacy of the National System of Parks!" How it Can Work for You: If you own property, you can aid in the preservation of America's parklands by participating in the National Park Trust's (NPT) PROPERTY FOR PARKS program. When you donate property to this program, NPT will sell it and use the money to help preserve our national system of parks. Since 1983 NPT has been the beneficiary of over $10 million worth of donated property. Our dedicated staff has more than 50 years of experience working with park issues. What are the benefits? Corporations and individuals donating real estate receive an immediate tax deduction and avoid capital gains taxes. For individuals, donation write-offs can be staged over a period of years to maximize donor benefits. Individuals donating real estate can reduce state and federal estate taxes. Gifts of real estate can be donated through a will or living trust, and can be used to fund Charitable Remainder Trusts. Individuals donating property can retain their right to use the property for their lifetime, and take an immediate charitable income tax deduction for a portion of the value (when designated as a life estate). NPT also accepts other marketable assets such as bounds, mutual funds and stocks. The National Park Trust will endeavor to use proceeds from this property for the types of parks and locations the donor prefers. If the donor wishes, we will also provide appropriate recognition of the donation as determined by the recipient park agency. NPT uses professional experts to help donors maximize benefits from their property. These experts on charitable giving, tax planning and real estate are available to you through the National Park Trust. The Property for Parks program has been announced in Fortune, Business Week, and other publications. The publicity and response from these publications show that there is a yearning across America to find creative solutions to solve what is clearly a commitment of all Americans: The preservation of America's parklands. For more information on how you can help the National Park Trust through the Property for Parks program, contact NPT at 202-548-0500 or online at email@example.com. http://www.parktrust.org/npt-report2/pfp_prog.html

A plant patent grants the right to exclude others from asexually reproducing the plant or selling or using the plant so reproduced. §§ 161-163.
Plant-pesticide - As proposed by EPA (November 23, 1994), plant-pesticides are all substances responsible for pest resistance in plants, as well as the genes needed for production of these substances. EPA has further proposed that plant-pesticide traits introduced into plants using recombinant DNA techniques should be registered under legal requirements of FIFRA and FFDCA. Exempt from tolerance requirements would be those defense substances and genes evolved naturally or transferred to the plant by traditional plant breeding methods.
Plant Regulator - A chemical that affects the physiological behavior of plants, for example through accelerating or retarding the rate of growth or maturation of produce. Typically the definition of plant regulator excludes nutrients. Plant regulators must be registered as pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act.
Plant products - Unmanufactured material of plant origin (including grain) and those manufactured products that, by their nature or that of their processing, may create a risk for the introduction and spread of pests. - UN/FAO International Plant Protection Convention Glossary
Plant Variety Protection Act of 1970 - P.L. 91-577 (December 24, 1970) was enacted to provide patent-like protection for new non-hybrid seed varieties. The ultimate goal was to create an incentive for public and private research on new commercial plant varieties by making it possible for scientists to benefit financially from developing them. The Plant Variety Protection Act Amendments of 1994 ( P.L. 103-349, October 6, 1994) made the law consistent with the International Convention for the Protection of New Varieties of Plants of March 19, 1991, to which the United States is a signatory. The law now ensures that new varieties are protected as intellectual property, as defined under the International Convention for the Protection of New Varieties of Plants. USDA rather than the Patent and Trademark Office, administers the law.

Point Source (of) Pollution - Pollutants that are discharged or emitted from discrete 'point' sources, such as pipes and smokestacks. Both the Clean Water Act and the Clean Air Act focus control requirements on point sources and both require permits for major sources of discharges from point sources. While much agricultural pollution is non-point source, some agricultural activities are affected: for example, feedlots of over 1000 animal units are considered point sources requiring permits under the Clean Water Act. However, irrigation return flows, although considered point sources, are expressly exempted from the permit requirement.

Polluted Water - Water containing a natural or human-made impurity. The water is classified as polluted when the concentration of the pollutant exceeds the acceptable standard for a particular use. Water that contains disease-causing or toxic substances is said to be contaminated.
Pollution/Contamination - A pollutant is any substance that is introduced into a water resource, naturally or by human activities, in sufficient amounts to adversely affect the quality of the resource for a specific use. Water pollution refers to the undesirable change in the condition of water to the point where the potential of the water for a specific use is limited or impaired. When the quality of a water resource falls below an acceptable level for a particular use, the water may be classified as polluted or contaminated. Pollution and contamination are very similar in meaning and often are used interchangeably. Contamination historically has related to water containing disease-causing or toxic substances that prevent or reduce the potential for use of that water. In recent times, the term contamination has been used to define the act of degrading the quality of a water supply or making a water supply impure, and to indicate that chemicals, sediments, or bacteriological impurities are present in water.
Pollution Prevention Act - 42 U.S.C. 13101 and 13102, s/s et seq. (1990) The Pollution Prevention Act focused industry, government, and public attention on reducing the amount of pollution through cost-effective changes in production, operation, and raw materials use. Opportunities for source reduction are often not realized because of existing regulations, and the industrial resources required for compliance, focus on treatment and disposal. Source reduction is fundamentally different and more desirable than waste management or pollution control. Pollution prevention also includes other practices that increase efficiency in the use of energy, water, or other natural resources, and protect our resource base through conservation. Practices include recycling, source reduction, and sustainable agriculture.

Population - A group of individuals with common ancestry that are much more likely to mate with one another than with individuals from another such group. - UNDP/WRI
Population - Is the total membership or population or 'universe' of a defined class of people, objects, or events. There are two types of population viz. target population and survey population. A target population is the population outlined in the survey objects about which information is to be sought and a survey population is the population from which information can be obtained in the survey. The target population is also known as the scope of the survey and the survey population is also known as the coverage of the survey. For administrative records the corresponding populations are: the `target population' as defined by the relevant legislation and regulations, and the actual `client population'. (UN)

Population Growth - The increase in a country's population, divided by the population. It reflects the number of births and deaths and the number of people moving to and from a country. Usually expressed as an annual average rate. (UNESCO)
Population Growth Rate (average annual) - The increase in a country's population during one year, divided by the population at the start of that year. It reflects the number of births and deaths during the period and the number of people moving to and from a country. The average annual population growth rates for a period of years provide a better picture than do rates for a single year. In 1998 total world population was more that 5.8 billion, and the average world population growth rate was between 1980 and 1998 1.6. (WB-UN)
Population Momentum - The tendency for population growth to continue beyond the time that replacement-level fertility has been achieved because of a relatively high concentration of people in the childbearing years. For example, the absolute numbers of people in developing countries will continue to increase over the next several decades even as the rates of population growth will decline. This phenomenon is due to past high fertility rates which results in a large number of young people. As these youth grow older and move through reproductive ages, the greater number of births will exceed the number of deaths in the older populations. (UNESCO)
Population Projections - Demographers make predictions about future population based on trends in fertility, mortality, and migration. (UNESCO)

Preseault v. US - INTRODUCTION AND SUMMARY. In brief, the issue in this case is whether the conversion, under the authority of the Rails-to-Trails Act and by order of the Interstate Commerce Commission, of a long unused railroad right-of-way to a public recreational hiking and biking trail constituted a taking of the property of the owners of the underlying fee simple estate. At this point we shall refer to the railroad's interest in the property by the term "right-of-way." That term is sufficient to indicate that the railroad had obtained a property interest allowing it to operate its equipment over the land involved. Later in the opinion it will become important to more precisely delineate the nature of the railroad's property interests, after which the use of the term "right-of-way" will refer only to those defined interests. The facts of the case are reported in full in the several opinions already rendered in connection with this matter: the decision of the United States Court of Appeals for the Second Circuit, holding the Rails-to-Trails Act constitutional and the Preseaults without remedy, Preseault v. ICC, 853 F.2d 145 (2d Cir. 1988) (Preseault I)5; the decision of the United States Supreme Court, on certiorari from the Second Circuit, affirming the constitutionality of the Rails-to-Trails Act on its face, but concluding that the Preseaults may have a remedy in the Court of Federal Claims under the Tucker Act for a Fifth Amendment "taking," Preseault v. ICC, 494 U.S. 1 (1990) (Preseault II); the initial decision of the Court of Federal Claims, Preseault v. United States, 24 Cl. Ct. 818 (1992) (Preseault 1), in which the trial judge, after hearing and argument, granted partial summary judgment for the Preseaults, and denied the Government's cross-motions for summary judgment; and the final judgment of the Court of Federal Claims, reported at 27 Fed. Cl. 69 (1992) (Preseault 2), concluding that the law was against the Preseault's claim for compensation under the Fifth Amendment, granting the Government's second cross-motion for summary judgment, and ordering judgment dismissing the complaint.[6 There are also two decisions in related matters by the Supreme Court of Vermont. The first, in 1985, holds that affected property owners (in that case the Preseaults and others) cannot maintain a suit in state court for a declaration of rights concerning the matter at issue before us because the matter is exclusively within the province of the Federal Government pursuant to the provisions of the Interstate Commerce Commission Act, and that the state court is therefore without subject matter jurisdiction. ]Trustees of the Diocese of Vermont v. State, 145 Vt. 510, 496 A.2d 151 (1985). The second state court decision, some ten years later, affirms an injunction against the Preseaults prohibiting them from using that part of their property subject to the original right-of-way for any purpose other than as members of the general public. State v. Preseault, 652 A.2d 1001 (Vt. 1994). In light of this record, we refer the reader to the earlier opinions for the full details of the events leading up to this appeal. For purposes of the decision here we summarize and condense that history, and recite only the salient facts relevant to the decision. On appeal we affirm a summary judgment if the record before us discloses that "there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law." Fed. R. Civ. P. 56(c). Although we give due consideration to the views of the trial court, we decide anew questions about the applicable law, without deference to those views. In summary, we conclude that the trial court was correct in finding that the 1899 transfers to the railroad created easements for use for railroad purposes; the fee estates remained with the original property owners. (Part C.1.) We accept the Government's position that ultimately this is a matter to be decided under controlling federal law and Constitution, but we reject the Government's central thesis that general federal legislation providing for the governance of interstate railroads, enacted over the years of the Twentieth Century, somehow redefined state-created property rights and destroyed them without entitlement to compensation. (Part C.2.) The trial court erred in accepting that thesis. As far as the Government's defenses based on the state's property law are concerned, we conclude that even if these easements were still in existence at the time the trail was created, there was no legal justification for the intrusion upon the Preseault's property. We find no support in Vermont law for the proposition, propounded by the defendants and accepted by the dissent, that the scope of an easement limited to railroad purposes should be read to include public recreational hiking and biking trails (Part D). But we find no clear error in the trial court's determination that in fact these easements had been abandoned years before the creation of the trail (Part E), and that determination is affirmed. Finally, we conclude that the taking that resulted from the establishment of the recreational trail is properly laid at the doorstep of the Federal Government. Whether the State's role in the matter should have resulted in liability for the State, or whether the State could absolve itself by pointing to the Federal Government, as the State Court held, is immaterial. The Federal Government authorized and controlled the behavior of the State in this matter, and the consequences properly fall there. (Part E.)

Island remnants are the structures remaining after stand initiating disturbances and will therefore be most important where stand-initiating disturbances are predominant. - Biodiversity Guidebook Glossary
Present Net Value (PNV) - Also called present net worth; the measure of the economic value of a project when costs and revenues occur in different time periods. Future revenues and costs are "discounted" to the present by an interest rate that reflects the changing value of a dollar over time. The assumption is that dollars today are more valuable than dollars in the future. PNV is used to compare project alternatives that have different cost and revenue flows.
Presentation - The World Heritage Convention does not specifically define presentation. Throughout the Convention reference is made to the "identification, protection, conservation, presentation and transmission to future generations of the cultural and natural heritage". Article 5 of the Convention makes reference to a number of "effective and active measures" that can be taken by States Parties in ensuring this "identification, protection, conservation, presentation and transmission" (UNESCO 1972). Although presentation is used very frequently in the Operational Guidelines it is not defined. - Glossary of World Heritage Terms

In addition, some bacteria in the deep sea can convert chemical energy to biomass through chemosynthesis. Primary production refers to the amount of material produced. Net primary production is the measure of the actual accumulation of biomass after some of the products of photosynthesis (or chemosynthesis) are expended for the plant's own maintenance. Productivity, or the rate of production, is affected by various environmental factors, including the amount of solar radiation, the availability of water and mineral nutrients, and temperature. - UNDP/WRI
Primary sample unit (PSU) - An area of land, typically square to rectangular in shape, that is approximately 40, 100, 160, or 640 acres in size. Within the PSU, sample points are assigned. Certain data elements are collected for the entire PSU, while others are collected at the PSU points. The size of the PSU is based on the shape, size, and complexity of the resources being inventoried. In 34 states, PSU's are often 160-acre square parcels measuring 0.5 mile on each side. In the western United States, PSU's are often 40-acre or 640-acre square areas; the 40-acre units are used in most irrigated areas, and the larger PSU's are used in relatively homogeneous areas containing large tracts of rangeland, forest land, or barren land. In the 13 northeastern states, PSU's are defined to be 20 seconds of latitude by 30 seconds of longitude, ranging from 97 acres in Maine to 114 acres in southern Virginia.

Prime Farmland - Land that is best suited to and available for the production of food, feed, forage, fiber, and oilseed crops. It can be cropland, pastureland, rangeland, forestland, or other land. It has the soil quality, growing season, and moisture needed to produce high yields of crops each year economically, if managed according to acceptable farm practices. Prime farmland produces the highest yields with minimal expenditure of energy and economic resources and does so with the least damage to the environment. Of the 334 million acres of prime farmland, 216 million are in cropland use, according to the 1992 national resources inventory. See also unique farmland. Land that has the best combination of physical and chemical characteristics for producing food, feed, fiber, forage, oil seed, and other agricultural crops with minimum inputs of fuel, fertilizer, pesticides, and labor and without intolerable soil erosion, as determined by the Secretary of Agriculture. It does not include land that is already committed to urban development or storage. Only 3.1% of the Earth's surface is prime farmland.
Prime farmland - Prime farmland is land on which crops can be produced for the least cost and with the least damage to the resource base. Prime farmland has an adequate and dependable supply of moisture from precipitation or irrigation and favorable temperature and growing season. The soils have acceptable acidity or alkalinity, acceptable salt and sodium content and a few rocks. They are not excessively eroded. They are flooded less often than once in two years during the growing season and are not saturated with water for a long period. The water table is maintained at a sufficient depth during the growing season to allow cultivated crops common to the area to be grown. The slope ranges mainly from 0 percent to 5 percent. To be classified as prime, land must meet these criteria and must be available for use in agriculture. Land committed to non-agricultural uses is not classified as prime farmland. [Source: USDA-SCS, 1982 NRI] 2. Land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and is also available for these uses. - National Resources Inventory
Primitive - One of the six classes of the recreation opportunity spectrum. Primitive areas offer recreation opportunities for isolation from the sights and sounds of human activities, where a visitor can feel a part of the natural environment, experience a high degree of challenge and risk, and use outdoor skills. - BLM
Primitive Area - An area that is composed of natural, undeveloped lands that are essentially unaffected by civilization and located where the natural environment can be preserved by management of recreation activities and exclusion of additional roads and commercial developments." - BLM (Note: Primitive areas have not been previously defined by the BLM. The term, generally applied to Forest Service lands, has not been used much since the passage of the Wilderness Act when existing primitive areas were declared Wilderness by Congress. This definition opens the door for more restrictive and exclusionary management of lands not now considered "roadless" or part of a Wilderness inventory.)
Primitive Recreation Opportunity Spectrum (PROS) - A classification of wilderness and recreation opportunity. It is characterized by an essentially unmodified environment, where trails may be present but structures are rare, and where it is highly probably to be isolated from the sights and sounds of people.

Proposal (40 CFR 1508.23) - A "proposal" exists at that stage in the development of an action when the action sponsor has a goal and is actively preparing to make a decision on one or more alternative means of accomplishing that goal and the effects can be meaningfully evaluated. A proposal may exist in fact as well as by agency declaration that one exists. (USGS, Environmental Management and Compliance Requirements Handbook, SM 445-1-H)
Protected area - An area that has protected designation according to provincial or federal statute. Protected areas are land and freshwater or marine areas set aside to protect the province's diverse natural and cultural heritage. - Biodiversity Guidebook Glossary
Protection - To provide a historic site or property with a defensive system intended to inhibit further loss or deterioration of the existing physical fabric. - NPS Architecture, Fortifications, and Preservation glossary
Protection - The imposition of import tariffs, import quotas, or other barriers that restrict the flow of imports. The opposite of "free trade." Used to: Protect "strategically important" industries- such as agriculture- without which a country would be vulnerable in times of war. Protect new industries until they are strong enough to compete in international markets. Retaliate against protectionist policies of trade partners. Since World War II protectionist policies have been significantly reduced in most countries through negotiations under the General Agreement on Tariffs and Trade (GATT). 2. The World Heritage Convention does not specifically define protection. Throughout the Convention reference is made to the "identification, protection, conservation, presentation and transmission to future generations of the cultural and natural heritage". Article 5 of the Convention makes reference to a number of "effective and active measures" that can be taken by States Parties in ensuring this "identification, protection, conservation, presentation and transmission" (UNESCO 1972). Although protection is used very frequently in the Operational Guidelines it is not defined (UNESCO February 1996). Protection is used interchangeably with conservation, safeguarding and preservation in the Operational Guidelines. See Conservation, International protection, National protection, Preservation, Safeguarding - Glossary of World Heritage Terms
Protected Area - Legally established land or water area under either public or private ownership that is regulated and managed to achieve specific conservation objectives (United Nations).

(d) All protests to the regional director shall be filed within 90 days from the date of receipt of the payment. (e) The regional director shall consult with the affected county to resolve conflicts in the computations and/or data. The regional director shall make a determination as to the correct payment, which determination shall be final and conclusive.
Protocol - A treaty which modifies another treaty (e.g., adding additional procedures or substantive provisions). - United Nations Charter / Human Rights Glossary 2. An amendment or addition to a treaty or convention. - UNEP Children's Glossary
Protocols - The term "protocol" is used for agreements less formal than those entitled "treaty" or "convention". The term could be used to cover the following kinds of instruments: (a) A Protocol of Signature is an instrument subsidiary to a treaty, and drawn up by the same parties. Such a Protocol deals with ancillary matters such as the interpretation of particular clauses of the treaty, those formal clauses not inserted in the treaty, or the regulation of technical matters. Ratification of the treaty will normally ipso facto involve ratification of such a Protocol. (b) An Optional Protocol to a Treaty is an instrument that establishes additional rights and obligations to a treaty. It is usually adopted on the same day, but is of independent character and subject to independent ratification. Such protocols enable certain parties of the treaty to establish among themselves a framework of obligations which reach further than the general treaty and to which not all parties of the general treaty consent, creating a "two-tier system". The Optional Protocol to the International Covenant on Civil and Political Rights of 1966 is a well-known example. (c) A Protocol based on a Framework Treaty is an instrument with specific substantive obligations that implements the general objectives of a previous framework or umbrella convention. Such protocols ensure a more simplified and accelerated treaty-making process and have been used particularly in the field of international environmental law. An example is the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer adopted on the basis of Arts.2 and 8 of the 1985 Vienna Convention for the Protection of the Ozone Layer. (d) A Protocol to amend is an instrument that contains provisions that amend one or various former treaties, such as the Protocol of 1946 amending the Agreements, Conventions and Protocols on Narcotic Drugs. (e) A Protocol as a supplementary treaty is an instrument that contains supplementary provisions to a previous treaty, e.g. the 1967 Protocol relating to the Status of Refugees to the 1951 Convention relating to the Status of Refugees. (f) A Process-Verbal is an instrument that contains a record of certain understandings arrived at by the contracting parties. (UN)

Provincial Advisory Council (PAC) - See Resource Advisory Council. - BLM
Provisional Application and Provisional Entry into Force of Treaties - 1. Provisional Application - The growing use of provisional application clauses in treaties is a consequence of the need felt to give effect to treaty obligations prior to a state's formal ratification of/accession to a treaty. The obligations relating to provisional application are undertaken by a conscious voluntary act of the state consistent with its domestic legal framework. Provisional application of a treaty that has entered into force - The provisional application of a treaty that has entered into force may occur when a state undertakes to give effect to the treaty obligations provisionally although its domestic procedures for ratification/accession have not yet been completed. The intention of the state would be to ratify/accede to the treaty once its domestic legal requirements have been met. Provisional application may be terminated at any time. In contrast, a state which has consented to be bound by a treaty through ratification/accession or definitive signature, is governed by the rules on withdrawal specified in the treaty concerned (Arts. 54, 56, Vienna Convention on the Law of Treaties 1969). [Art. 25, Vienna Convention on the Law of Treaties 1969] (UN) Provisional application of a treaty that has not entered into force - Provisional application of a treaty that has not entered into force may occur when a state notifies that it would give effect to the legal obligations specified in that treaty provisionally. These legal obligations are undertaken by a conscious voluntary act of the state consistent with its domestic legal framework. Provisional application may be terminated at any time. In contrast, a state which has consented to be bound by a treaty through ratification/ accession or definitive signature, is governed by the rules on withdrawal specified in the treaty concerned (Arts. 54, 56, Vienna Convention on the Law of Treaties 1969). Provisional application may continue even after the entry into force of the treaty in relation to a state applying the treaty provisionally until that state has ratified it. Provisional application terminates if a state notifies the other states among which the treaty is being applied provisionally of its intention of not becoming a party to the treaty. [Art. 25 (2), Vienna Convention on the Law of Treaties 1969] (UN)
Provisional Entry into Force - There are also an increasing number of treaties which include provisions for provisional entry into force. Such treaties provide mechanisms for entry into force provisionally, should the formal criteria for entry into force not be met within a given period. Provisional entry into force of a treaty may also occur when a number of parties to a treaty which has not yet entered into force, decide to apply the treaty as if it had entered into force. Once a Treaty has entered into force provisionally, it is binding on the parties that agreed to bring it into force provisionally. The nature of the legal obligations resulting from provisional entry into force would appear to be the same as the legal obligations in a treaty that has entered into force, as any other result would create an uncertain legal situation. It is the criteria for formal entry into force that have not been met but the legal standard of the obligation remains. [Art. 25 (1), Vienna Convention on the Law of Treaties 1969] (UN)

Public goods - Goods that are nonrival- consumption by one person does not reduce the supply available for others- and nonexcludable- people cannot be prevented from consuming them. These characteristics make it impossible to charge consumers for public goods, so the private sector is not interested in supplying them. Instead, they are often supplied by government. Public goods are usually national or local. Defense is a national public good- benefiting the entire population of a country. Rural roads are local public goods, benefiting a smaller group of people. There can also be global public goods, benefiting most of the world's population, for example global peace and security, or information needed to prevent global climate change. Providing such goods (and services) is a function of international organizations. - WB
Public Health, Safety and Welfare - This catchall phrase and the police power to restrict nuisance have enabled zoning agencies to assume great power over private property. Fighting this power on a basis of freedom of the individual has been less effective than on the basis of due process. The due process clause has come to be "the home of much takings law,"(1) according to Richard A. Epstein, of the University of Chicago. Substantive due process must be observed: The content of the regulation must be designed to accomplish a valid public purpose, be reasonable (not arbitrary or capricious), be fair, and be within the authority of the government agency. Procedural due process requires that procedure by which the regulation is adopted and administered must be fair to the interests that are affected, "giving them notice and a reasonable chance to be heard before an accessible and impartial tribunal."(2) Zoning must be "accomplished in a proper, careful and reasonable manner." (Udall v. Hass 21 N.Y. 2d. 463 (1968)(3) Perhaps the assumption of adequacy of public health, safety and welfare goals will be less all-sufficient, considering, Lucas v. South Carolina Coastal Commission (U.S. Supreme Court 1992), which held: "To win its case, respondent cannot simply proffer the legislature's declaration that the uses Lucas describes are inconsistent with the public interest, or the conclusory assertion that they violate a common-law maxim such as sic utere tuo ut alienum non laeduas (use your property in such a manner as not to injure that of another), but must identify principles of nuisance and property law that prohibit the uses Lucas now intends in the property's present circumstances." - Zoning (Case Law) Glossary
Public hearing - A public proceeding conducted for the purpose of acquiring information or evidence which will be considered in evaluating a proposed transportation project and/or a DA permit action and which affords the public an opportunity to present their views, opinions, and information on such projects and permit actions. See 33 CFR § 327.3(a).
Public Involvement - The use of appropriate procedures to inform the public, obtain early and continuing public participation, and consider the views of interested parties in planning and decision making.
Public Land - Land or interest in land owned by the United States and administered by the Secretary of the Interior through the BLM, except lands located on the Outer Continental Shelf, and land held for the benefit of Indians, Aleuts, and Eskimos. - BLM
Public Lands/Public Lands Of The United States - As defined in U.S. Public Law 94-79, public lands are any land and interest in land outside of Alaska owned by the United States and administered by the Secretary of the Interior through BLM. In common usage, public lands may refer to all federal land no matter what agency has responsibility for its management. As defined in the Federal Land Policy and Management Act, public lands are any land and interest in land outside of Alaska owned by the United States and administered by the Secretary of the Interior through the Bureau of Land Management. In common usage, public lands may refer to all federal land no matter what agency has responsibility for its management or may refer even to state- and local municipality-owned lands. Land for which title and control rests with a government -- Federal, state, regional, county, or municipal.
Public Lands Surveys, or Public Land Survey System (PLSS) - 1) In general, the survey of Federal or State lands or the lands of any other public body. The term, however, is commonly used to designate the cadastral survey of the public lands of the U.S.; originally the Government land Office (GLO) surveys; the present surveys executed by the Bureau of Land Management (B.L.M.). Synonymous with rectangular surveys of the U.S. lands; or the rectangular survey system. - Cadastral Data glossary 2) 3.11 U.S. Public Land Survey System -- Major Code 300 -- The Public Land Survey System (PLSS) and other special surveys within, and exclusions from, public domain lands, are shown on USGS quadrangle maps. Survey corners, lines, and areas within public domain States are mapped and are collected as DLG-3 data. All States, except the following, are public domain States: Connecticut, Delaware, Georgia, Hawaii, Kentucky, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Vermont, and West Virginia. The public domain includes the land ceded to the Federal Government by the Thirteen Original States and acquired from native Indians and foreign powers. The surveys of the public domain can be classified into the following general types: Land Grants - Land grants were conferred on individuals by a predecessor government and were never part of the public domain. PLSS Area - The rectangular system of surveys was developed to divide the public lands for disposal by the government. This survey system typically divides the land into 6-mile square townships, which are further subdivided into 1-mile square sections, although there are departures from this regular system. Private Surveys - The government is responsible for conducting these surveys, but some land has been surveyed by private surveyors who have extended the PLSS using the rectangular system of surveys. Special Survey Areas - Some land was disposed of by special surveys that were usually the result of acts of Congress. These include U.S. surveys, homestead entry surveys, Indian allotments, and donation land claims. Special survey areas are not subdivided by rectangular surveys. Waterbodies - Navigable water ways and water bodies over 50 acres were not subject to disposal and were not subdivided by surveys. Reservations - Other land was "reserved" by the Federal Government, and not subject to disposal, such as national parks, forests, and Indian reservations. These lands may contain subdivision lines if the reservations were established after the area had been surveyed. For additional background information on the PLSS and its associated types of survey areas, lines, and corners, see Appendix 3.11.A. 3.11.1 General Principles - Because the PLSS depicted on the graphic cannot be revised from photographs, there is no photorevised feature code in this category. 18.104.22.168 Node Attribute Codes - Node attribute codes are collected only when a monumented survey corner or point has been recovered in the field and is identified on the graphic. All other nodes are unattributed. Do not make any assumptions about survey corners, even if boundary monuments or control stations are shown. Only one code from the list of node attribute codes is assigned to any given node. Changes in azimuth along a survey line, which are not represented by a recovered corner or point, are collected simply as inflection points on the line. 22.214.171.124 Area Attribute Codes - All areas are attributed. Only one code from the list of area attribute codes is assigned to each polygon, except in the case of a land grant that is also a private extension of the public land survey. - Each area code description contains information on which parameter codes are used in conjunction with that area code. Several coding descriptions say: "Used in conjunction with parameter codes 301-305, as appropriate." This means that the township number, the range number, and the section number are collected, if they can be determined from the graphic. If a section number is collected, township and range numbers must be collected. Areas that make up a section, or unsectionalized areas that cannot be assigned any other code from the list of area attribute codes, are considered PLSS areas (300 0110). There are a number of departures from the rectangular survey system. Areas were surveyed, generally by acts of Congress, for such things as wagon roads, coal leases, railroad grants, and small-holding claims. Only a few of these survey areas are uniquely identified on USGS maps and in the DLGs (see below). Other non-rectangular surveys that interrupt the regular rectangular grid are attributed as PLSS area (300 0110). These areas generally do not have a section number. Special surveys (homestead entry surveys, donation land claims, tracts, U.S. surveys, and Indian allotments), land grants, private surveys, water areas, and area outside of the public domain are not considered as PLSS area. How to collect: Evaluation of the limiting survey lines or the label within the area or along the survey line, or both, is required to determine the correct area attribute and the extent of the area to be collected. PLSS areas that have section numbers and are not completely closed off by mapped survey lines are closed off with a closure line or unattributed survey line (see section 126.96.36.199). Areas of old reservations, such as Indian, military, and lighthouse, have been identified on the map. Where their extent defines the limiting lines of a subdivision, the limiting lines are collected as survey lines, and the areas are assigned the appropriate code from the list of area attribute codes, but the reservation type is not identified. Other surveys that do not conform to the rectangular system of surveys, such as tracts, donation land claims, and Indian allotments are collected as shown on the map. In a number of States special survey areas that do not meet the collection criteria for homestead entry surveys, donation land claims, tracts, U.S. surveys, Indian allotments, or land grants have been shown on the map. They are collected as PLSS areas, and assigned no additional codes, even though they may be numbered or lettered. Survey areas in Ohio are unique in that various reference systems and subdivision schemes were used and a mix of public and private surveys exist. See Appendix 3.11.A for more detailed information on these surveys. 188.8.131.52 Line Attribute Codes Subdivision lines shown by symbols 502, 504, 508, 509 (A), 123.1, 123.2 (B), 523.1, 523.2, 523.12, 523.13 (C), or 2502.03, 2502.05, 2503.01, 2503.02 (D) are collected as unattributed lines. (On maps published before about 1940, subdivision lines were shown by black dotted lines; on those published between about 1940 and 1948, black solid lines were used.) In addition to depicted land lines, other lines that limit the land net must be digitized to complete closure of all polygons. Where survey lines have been dropped on the map because of coincidence with another linear feature, such as a road or boundary, an unattributed line is collected unless the overall pattern of the surrounding portrayed lines indicate the line is approximate. If a land line is dropped for a boundary that is labeled approximate or symbolized as indefinite, code the land line as approximate. Survey lines that have been dropped because of coincidence with other features are generally collected as straight lines connecting section corners, even if the feature they have been dropped for deviates from that straight line. Where survey lines are not shown on the map for reasons other than coincidence with another feature (most commonly in areas where there was insufficient evidence to map the survey lines, or in the vicinity of water bodies), the area is required to be closed off with a line when a section number is shown. A closure line (300 0203) is collected. The extent of old reservations, such as Indian, military, and lighthouse, shown on maps with the land grant or section line symbol and labeled, are collected as section lines where they form the limit of subdivisions of the rectangular system of surveys. Where these lines do not form the limit of a subdivision of a rectangular survey, they are not collected in any category.

This code also identifies arpent sections in Louisiana, delineated by symbols 500(A), 123.5(B), 523.10(C), or 2502.01(D). An area that does not contain land lines and to which no other area code applies, (either because the area has not been surveyed or because there was not enough information to locate the lines) is also identified with this code. Except when used as described in the following paragraph, this code must be used in conjunction with parameter code 306. Used in conjunction with parameter codes 301-305, as appropriate. This code is also applied to any area delineated by symbols 500(A), 123.5(B), 523.10(C), or 2502.01(D), which does not meet the collection criteria for codes 300 0101 through 300 0103 or 300 0111 through 300 0113 (homestead entry survey, donation land claim, land grant, tract, U.S. survey, or Indian allotment). In these areas, this code is used alone, without any additional parameter codes, even though the area may be identified by a number or letter on the map. 300 0111 Tract - This code identifies an area delineated by symbols 500(A), 523.10(C), or 2502.01(D). Tracts are not labeled, but contain an area survey number. They lie in more than one section and are never wholly contained within a section.

Must be used in conjunction with parameter code 307 to identify the area survey number. 300 0113 Indian allotment - This code identifies an area shown by symbols 500(A), 523.10(C), or 2502.01(D). Must be labeled "Indian Allotment." Area will also contain an area survey number. Must be used in conjunction with parameter code 307 to identify the area survey number. 300 0114 Area outside of the public domain - This code identifies an area outside of the public domain. It is used wherever a portion of Canada, Mexico, or any State which is not part of the public domain is shown on a map of a public domain State. Cannot be used in conjunction with any parameter codes. 300 0198 Water - This code identifies an area of water (which may include some adjacent land areas) across which the land net cannot be extended with closure lines. The area is generally bounded by closure lines that close off the sections on either side of the water body. Cannot be used in conjunction with any parameter codes. 300 0199 Unsurveyed area - This code is no longer used. See code 300 0110 for unsurveyed PLSS areas. See code 300 0114 for areas outside of the public domain. 3.11.4 Line Attribute Codes 300 0201 Approximate position - This code identifies a line shown by symbols 503, 505 (A); 523.3, 523.4 (C); or 2502.04, 2503.06 (D). Land grant lines that are labeled "Approximate" are also assigned this code. When only a portion of a land grant line is labeled approximate, the entire segment between the nearest found grant monument on either side of the labeled portion of the line is assigned this code. 300 0202 Protracted position - This code identifies a line shown by symbols 123.3(B), 123.4(B), 523.16(C), or 523.17(C). Currently, on 1:24,000-scale maps, protracted lines are shown only in Alaska. On 1:100,000-scale maps, protracted lines may be show in any public land State. 300 0203 Closure line - This code identifies an arbitrary line digitized to separate two or more areas that must be assigned different sets of attribute codes. Closure lines are needed only if areas are still not closed off from one another after all the survey lines that have been dropped on the map because of coincidence with linear features have been collected, as described in section 184.108.40.206. Why do unclosed areas appear on the map? - Survey lines may be missing on the map because there was insufficient evidence on the ground to complete the grid, because the survey lines were interrupted by a waterbody that was segregated from the public domain, or because the area was not surveyed. What areas need to be closed off? - Only those areas on the map that have a section number or areas with different township and range numbers, that are not completely enclosed by survey lines need to be closed off. On 1:100,000-scale maps, usually only sections 1, 6, 31, and 36 are labeled, so other sections may need to be closed off, even when no section number is shown. How should closure lines be used? - In closing off areas, the preferred approach is to assume a regular grid and to use closure lines to add any lines needed to approximate that regular grid. As noted above, it is not necessary to complete the entire grid; only those areas that must be assigned different sets of attribute codes must be closed off from one another. An area that has not been surveyed is collected as a single PLSS area (300 0110), with no code for section numbers. A large water body or portion of a water body with no section lines or section numbers is collected as Water (300 0198). If it is not possible to assume a regular grid, either because the map contains areas with different surveys that do not line up, or because there are not enough corners or portions of section lines to determine if the grid is regular, then the areas must be closed off. Generally the closure line is collected as a straight line connecting the end points of the depicted survey lines. In some cases, though, it may be desirable to add a few points to roughly approximate the extent of the section, as indicated by the position of the section number, or the shoreline, or both. Keep in mind that range lines may be offset when they cross township lines. Although it may at first glance appear as though the survey lines to the north and south of the interruption cannot be matched up with one another, often the regular grid can be assumed if this offset is taken into consideration. How should the regular grid be approximated? - The rectangular system called for sections to be 1 mile by 1 mile. Obviously, depending on the skill of the surveyor, the terrain, and other conditions, this may not have been achieved. However, by looking at the sections that are completed on the map, the location of the section numbers, isolated pieces of survey lines, and survey corners, the general grid can usually be determined. If you see an apparent section (a section number is present but not all of the surrounding survey lines are) complete the section by using the available information to create a square that is approximately 1 mile by 1 mile. It is not necessary to be exact when digitizing closure lines to approximate the grid. On USGS maps, the PLSS is shown as a reference grid, not to show ownership or parcel boundaries. 300 0204 Base line - This code is no longer used. The base line can be determined from the associated areas. 300 0299 Processing line - This code is described in section 220.127.116.11. 3.11.5 Single-Point Attribute Codes - 300 0300 Location or mineral monument - This code identifies a monument shown by symbols 227(A), 512.106(C), or 2102.12(D).

Public Law 480 (or P. L. 480) - P.L. 83-480 (July 10, 1954), also called Food for Peace, is the common name for food aid programs established by the Agricultural Trade Development and Assistance Act of 1954, which seeks to expand foreign markets for U.S. agricultural products, combat hunger, and encourage economic development in developing countries. Title I makes export credit available on concessional terms, for example, at low interest rates for up to 30 years. Donations for emergency food relief and nonemergency humanitarian assistance are provided under Title II. Title III authorizes a Food for Development program that provides government-to-government grant food assistance to least developed countries. The FAIR Act of 1996 extends the authority to enter into new P.L. 480 agreements through 2002.

PUL - Predominantly Urban Landscape
Pulp - Pulverized or ground ore in solution.
Pulp Mill - A highly mechanized industrial plant that processes wood into wood fiber (pulp) which is used to make paper and paper products. This chemical process is very water and energy intensive. Papers produced by either mechanical or chemical processes require bleaching where traditionally chlorine-based products are used (after pressure from environmental campaigns and consumers some pulp mills use an oxygen-based bleaching process). The pollutants produced in chlorine-based bleaching processes include some of the most potent poisons known. (UNESCO)

Purchase of Agricultural Conservation Easements (PACE) - PACE programs pay farmers to keep their land available for agriculture. Landowners sell an easement to a government agency or private conservation organization that is responsible for preventing development. Landowners retain full ownership and use of their land for agricultural purposes. PACE is also known as purchase of development rights (PDR), and as agricultural preservation restrictions (APR) in Massachusetts. [Source: AFT Farmland Information Library, 1996]
Purchase of Development Rights (PDR) - A program under which a government agency buys "development rights," or a conservation easement that permits it to prohibit practices, uses and development of the land in violation of the terms of the development right document. The program does not give the government agency the right to develop the land. It simply permits it to extinguish those rights in return for appropriate compensation. Landowners retain full ownership and control of their land (also known as PACE or APR, see above). [Source: AFT Farmland Information Library, 1996]
Purchaser Road Credits - Credits granted to purchasers of timber in the national forests in exchange for the construction of permanent roads specified in the timber sale contract. The amount of the credits is the Forest Service's estimate of construction costs, and the credits can be used to pay for timber cut. Occasionally, when stumpage prices are at or near the base rates, some or all of the credits cannot be used, and are then termed ineffective road credits.
Purchasing Power Parity (PPP) - 1. A method of measuring the relative purchasing power of different countries' currencies over the same types of goods and services. Because goods and services may cost more in one country than in another, PPP allows us to make more accurate comparisons of standards of living across countries. PPP estimates use price comparisons of comparable items but since not all items can be matched exactly across countries and time, the estimates are not always "robust." (WB-UN) 2. The number of currency units required to buy goods equivalent to what can be bought with one unit of the currency of the base country or with one unit of the common currency of a group of countries. Also referred to as Purchasing Power Standard. The PPP may be calculated over all of GDP, but also at levels of aggregation, like capital formation. (UN)
Purpose of Aid - The DAC statistics on the purpose of aid cover three dimensions: the sector of destination, the form or type of aid, and the policy objective(s) of aid.
