This study aims to undertake an economic analysis of technological, institutional and policy strategies for managing the effects of climatic variability and market risks in smallholder maize-legume systems in the northern regions of Ghana. The overall goal is to design appropriate adaptation strategies that would assist farmers to cope with climate change and variability and thereby increase their productivity. A key hypothesis to be tested in the research is that cultivation of legumes is a viable option to address the perennial problem of low soil fertility and could also be used as a hedge against climate and market risk. Various models will be developed/adapted and used to evaluate the tradeoffs and effects of technological and institutional innovations on farm household resource use, agro-ecosystem sustainability and welfare. The modelling results will be used to suggest policy instruments that can enhance adaptive capacity and mitigate the negative impacts of climate change.


Midterm report 2016:
This study investigated the impact of management practices such as soil fertility practices and sowing window on the profitability of the two popular maize varieties in Northern Ghana - obatanpa and dorke. On the basis of the results, we are able to draw some general conclusions about the effects of farm management practices on farm profitability. First, organic fertilizer could be equally profitable as inorganic fertilizer so long as sowing is undertaken in the first or second window. Organic fertilizer is not as profitable if the first two sowing windows are missed. In such cases, the economic gains from using organic fertilizer is not much different from conventional practice. These results have important implications for farm management practices in the face of future climate change. Given that
one of the effects of climate change would be delay in onset of rains, the results indicate that a useful adaptation strategy would be to use improved varieties of maize coupled with inorganic fertilizer.
