| Summary: | Using economic data from more than 8,500
household surveys across 10 African countries, this paper
examines whether the choice of farm type depends on the
climate and agro-ecological zone of each farm. The paper
also studies how farm type choice varies across farmers in
each zone, using a multinomial logit choice model. Farmers
are observed to choose from one of the following five types
of farms: rainfed crop-only, irrigated crop-only, mixed
rainfed (crop and livestock), mixed irrigated, and
livestock-only farming. The authors compare current
decisions against future decisions as if the only change
were climate change. They focus on two climate scenarios
from existing climate models: the Canadian Climate Centre
scenario, which is hot and dry, and the Parallel Climate
Model scenario, which is mild and wet. The results indicate
that the change in farm types varies dramatically by climate
scenario but also by agro-ecological zone. Policy makers
must be careful to encourage the appropriate suite of
measures to promote the most adapted farm type to each location. |
