520			_aAgroforestry is the cultivation, by farmers, of trees or other woody plants with crops or pasture. Its scientific study is attracting great interest and increasing funding because of its potential to produce sustainable agricultural systems and agroforestry is now included in most university and college courses covering land use subjects.
