摘要
Intensive monoculture agriculture has contributed greatly to global food supply over many decades,but the excessive use of agricultural chemicals(fertilizers,herbicides and pesticides)and intensive cultivation systems has resulted in negative side effects,such as soil erosion,soil degradation,and non-point source pollution[1].To many observers,agriculture looms as a major global threat to nature conservation and biodiversity.As noted in the Global Biodiversity Outlook 4[2],the drivers associated with food systems and agriculture account for around 70%and 50%of the projected losses by 2050 of terrestrial and freshwater biodiversity,respectively[3].
