The qualitative and quantitative evaluation of risks posed to health or the environment that arise from an activity, chemical use, or technology. The process includes describing potential adverse effects, evaluating the magnitude of each risk (e.g., the toxicity of a chemical), estimating potential exposure to the chemical or other hazard, estimating the range of likely effects given the likely exposures, and describing uncertainties.

The system of water allocation used in the humid eastern portion of the United States. Water may be used only by riparian landowners and it is recognized that all users will experience shortages periodically. In contrast with the prior appropriations system used in the arid West, water is not acquired by use, and access to it cannot be lost by lack of use.
Industry:Agriculture
A strip of vegetation along the bank of a body of water which slows the rate of flow of runoff from adjoining uplands, causing sediment and other materials to fall out onto the land before the runoff enters and pollutes the body of water.
Industry:Agriculture
Pertaining to or situated on or along the bank of a stream or other body of water. Often referred to in the context of cattle grazing and protection of streams for fish and wildlife habitat, and water quality purposes. Riparian rights refers to the entitlement of a land owner to certain uses of water on or bordering the property, including the right to prevent diversion or misuse of upstream waters (generally a matter of state law).
Industry:Agriculture
An erosion process in which numerous small channels, typically a few inches deep, are formed. It occurs mainly on recently cultivated soils or on recent cuts and fills.
Industry:Agriculture
Right to farm laws deny nuisance suits against farmers who use accepted and standard farming practices, even if these practices harm or bother adjacent property owners or the general public. Agricultural nuisances may include noise, odors, visual clutter and dangerous structures.
Industry:Agriculture
A type of soil conserving tillage in which the soil is formed into ridges and the seeds are planted on the tops of the ridges. The soil and the crop residue between the rows remain largely undisturbed. The practice offers opportunities to reduce crop production costs by banding fertilizers and pesticides and reducing the need for field trips.
Industry:Agriculture
A program that uses the repayments of existing loans to make additional loans to qualified borrowers. Initial capitalization of a revolving loan fund may be derived from federal appropriations or contributions from other sources.

Revisions to the universal soil loss equation implemented in the mid 1990s to more accurately predict soil erosion caused by water. It includes the same factors as the earlier formula; climate, soils, topographic conditions, and the degree to which the use and management of the soil reduces erosion. But it takes advantage of new knowledge about these relationships and the capabilities of computer technology. The comparison between predicted erosion and T-value is important in making and carrying out conservation plans and achieving conservation compliance.

A crop insurance program that provides coverage to producers against lost revenues (or incomes) caused by low prices, low yields, or a combination of low prices and low yields. An indemnity is paid to a producer when any combination of yield and price results in revenue that is less than a pre-specified revenue guarantee. The FAIR Act of 1996 mandates a USDA pilot program for crop years 1997-2000 under which producers of feed grains, wheat, soybeans, and other crops in specified areas may elect to receive insurance against loss of revenue. The two largest pilot programs to date are the Crop Revenue Coverage (CRC) program and the Income Protection (IP) program. The two programs are similar, except that the CRC allows farmers to insure their revenue at either planting-time prices or harvest prices, whichever is higher. The full cost of the premium associated with CRC and IP is paid by the participating farmer.
