Recent studies show that yields from ecological agriculture are broadly comparable to conventional yields in developed countries and significantly higher in developing countries, particularly where the existing system is low-input, which is largely the case for Africa.A study of a global dataset of 293 examples found that the organic/non-organic yield ratio was slightly less than 1.0 for studies in the developed world but more than 1.0 for developing countries. On average, in developed countries, organic systems produce 92 per cent of the yield of conventional agriculture, whereas in developing countries they produce 80 per cent more than conventional farms.
