The process whereby water or wind moves soil from one location to another. Types of erosion are (1) sheet and rill - a general washing away of a thin uniform sheet of soil, or removal of soil in many small channels or incisions caused by rainfall or irrigation run-off; (2) gully - channels or incisions cut by concentrated water run-off after heavy rains; (3) ephemeral - a water-worn, short-lived or seasonal incision, wider, deeper and longer than a rill, but shallower and smaller than a gully; and (4) wind - the carrying away of dust and sediment by wind in areas of high prevailing winds or low annual rainfall.
Integrated pest management (IPM)
The careful integration of a number of available pest-control techniques that discourage pest-population development and keep pesticides and other interventions to levels that are economically justified and safe for human health and the environment. IPM emphasizes the growth of a healthy crop with the least disruption to agro-ecosystems, thereby encouraging natural pest-control mechanisms.
In plant genetic resources, an early, cultivated form of a crop species, evolved from a wild population, and generally composed of a heterogeneous mixture of genotypes.
Plant genetic resources
The reproductive or vegetative propagating material of: (1) cultivated varieties (cultivars) in current use and newly developed varieties; (2) obsolete cultivars; (3) primitive cultivars (landraces); (4) wild and weed species, near relatives of cultivated varieties; and (5) special genetic stocks (including elite and current breeders' lines and mutants).
Any structure capable of giving rise to a new plant by asexual or sexual reproduction, including bulbils, leaf buds, etc.
Standard operating procedure (SOP)
An authorized written procedure giving instructions for performing an operation.
The use of components of biological diversity in a way and at a rate that does not lead to the long-term decline of biological diversity, thereby maintaining its potential to meet the needs and aspirations of present and future generations.
