This study evaluated the impact of climate change on yield and net revenue of beans production
in Nigeria using Feasible Generalised Least Square and Hedonic Ricardian Approach. Secondary
data were used for this study; monthly rainfall and temperature data from 1981 to 2019 were
obtained from Nigeria Meteorological agency while data on socioeconomic and demographic
characteristics as well as farm production for 2000 beans farmers across the six agro-ecological
zones were obtained from General household survey wave IV. The study reveals that beans crop
is sensitive to infinitesimal change in temperature than rainfall. The marginal impact analysis of
increasing temperature and rainfall indicated that a unit increase in rainfall decreased the net
revenue of beans by N14,997 per hectare, while a unit increase in temperature increased the net
revenue of the beans production in Nigeria by N15,316 per hectare. The adjusted mean yield of
beans will increase by 1.058kg per hectare with a unit increase in temperature while it will reduce
0.173 per hectare with a unit increase in rainfall. The study also examined the impact of predicted
climate scenarios from two models namely Canadian Climate Change and Parallel Climate Model
on net revenue for the years 2050 and 2100. All these models indicated increasing temperature
would have a positive impact on the net revenue from beans production for the year 2050 but the
impact will be negative by year 2100. This means there will be more profit from beans production
in year 2050 while in 2100 the beans farmers will produce at loss. Nigeria government should
therefore consider designing and implementing adaptation policies to counteract the harmful
impacts of climate change on beans production
