  • Abstract:

Climate change is expected to affect land area farmers cultivate as well as induce responses that are both beneficial
and detrimental. Hence, the need to advance sustainable pathways for Nigeria's agricultural growth. To support
policy action, the net effect of climate change impact on cropland was modelled using the Ricardian econometric
framework. The data set for empirical application was sourced from the National Bureau of Statistics of the Federal
Government of Nigeria. Specifically, the study used the socio economic data set of small farms collected in 2010
together with baseline historical climate observations for 40 years average and climate projections for 2050 sourced
from World Climate Data Base. Complementary data on population, soil and altitude were sourced from National
Population Commission (NPC) and Food and Agriculture Organization (FAO). Climate change reduced land value
by 62.79% for the whole country. The distribution across zones revealed reduction by 8.24%, 41.95%, 7.19% and
44.96% for guinea savannah, Sahel, Sudan Sahel and Savannah and increased marginally by 3.36% for forest agro
ecology.This raises policy imperatives for programmes that seek to improve on the quality of farm land using best
practices that are sustainable.
