The agriculture in the region is highly dependent on the climate , responsible for three-fourths of the variability in agricultural yields in the region . Irrigation is an important strategy for agricultural production in part of the region, but it accounts for no more than 8% of the total agricultural area in SA and 7% in CA . This practice faces potential impacts from reductions in surface water availability in future climate scenarios , enhanced by non-climate drivers such as land use changes  . The remaining fluctuation in yields relates to issues of infrastructure, market, economy, policy and social aspects. Good infrastructure, transport logistics, quality of roads and storage strongly influence the vulnerability of the agricultural sector .
