Abstract
This paper analyses the economic effects of temperature and rainfall variability
on the net income of the main cereal crops in Togo based on a semi-parametric
specification of the Ricardian model. The model provides a flexible functional
form of the non-linear relationship between farmers' net income and climatic
variables and evaluates the effect of climate variability on the net income of these
crops. Using data from the National Agricultural Census in Togo, temperature
and rainfall data from spatial interpolation over all prefectures and soil type data
for each locality, the results of the semi-parametric estimates reveal a complex
non-linear relationship of temperature and rainfall variability on the net income
of crops. In addition, a combination of crops and agro-forestry practices reduce
the effects of climate variability on net income from cereal crops. Furthermore,
variations in temperature and rainfall under socio-economic scenarios result
in lower net income from cereal crops. The projections show that long-term
variability in temperature and rainfall will have a negative impact on net income
and that the impact will be greater in 2050 for all crops.
