Crop and livestock production is a major source of two greenhouse gases, methane and nitrous oxide. The latter is produced by the leaching, volatilization and runoff of nitrogen fertilizers and the breakdown of crop residues and animal wastes. Through burning of biomass, agriculture also releases large quantities of carbon dioxide into the atmosphere. Agriculture also stands to suffer adversely from climatic change. In tropical environments the effects of climate change on agriculture and hence on the livelihoods of millions of rural farming populations are expected to be particularly negative. Average global temperatures are projected to rise by 0.5-10C by 2030 and by 1.4-5.80C by 2100. These higher temperatures will result in increased evapotranspiration

Smallholder farmers will wish to have access to practices that reduce their vulnerability to climate change. In the promotion of CA, the SCAP Project will be stimulating, facilitating and empowering rural smallholder-subsistence farmers to adapt for their own use farming Crop and livestock production is a major source of two greenhouse gases, methane and nitrous oxide.

Some cultivated areas will become unsuitable for cropping and some tropical grasslands may become increasingly arid. This may also expand the range of agricultural pests and diseases. Even now, farmers are alluding to increases in frequency and severity of extreme climatic factors such as floods and droughts. Rainfall patterns are also said to be
