Environmental policy

The term agrobiodiversity refers to genetic variability in plants, animals and micro-organisms of economic value. In the past, several thousand plants were used for purposes of food, feed, fibre, fuelwood, fertilizer and medicine. As agriculture advanced, the human food secruity systems began to depend not only on fewer and fewer plant species, but also on a small number of varieties. Such genetic vulnerability to pests and diseases as well as to soil and climatic stresses.
