Low-input farming projects, not reliant on chemical fertilisers and pesticides, have brought significant increases in food production in Africa, south-east Asia and South America, according to a UN report. Small-scale farmers can double food production within 10 years in Africa by using ecological methods rather than chemical fertilisers. In a review of agroecological farming projects, which focus on a minimal use of external inputs, like chemical fertilisers, in favour of controlling pests and disease with natural predators, mixed crop and livestock management and agroforestry (interplanting of trees and crops), the report found average increases in crop yield of 80 per cent in 57 less-industrialised countries. In Africa the average increase was 116 per cent.... Conventional farming relies on expensive inputs, degrades soils, fuels climate change and is not resilient to climatic shocks. It simply is not the best choice anymore today. Schutter said in the long run agroecological farming would build long-term resilience for countries and make them less reliant on expensive imports based on oil and gas, chemicals and pesticides.
