Economic impact of climate change on Nigeria's agriculture: a conceptual framework

Total impact of climate change (CC) on Nigeria's agriculture will be realised through direct and indirect pathways with a secondary effect on the economy. Impact however, depends on the capacity of the sector to manage CC risk and uncertainty. The review reveals sparse literature on this issue for Nigeria compared to the whole of Sub–Saharan Africa, South Africa and the USA. Observable climate attributes and less of extreme events are often modelled over varying assumptions on greenhouse gases emissions within a marginal context. While necessary for policy direction, inappropriate application of a marginal method to a strongly non–marginal context is likely to downplay issues of equity, rights and responsibility.
