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.
