摘要：The study was conducted in north central Nigeria to determine current and future economic effects of climate change on sorghum. Data were collected from 147 respondents purposively selected based on farm experience of 10 years and abov e. Mean Annual rainfall, and precipitations data (1951-2011) were collected from the Nigeria MeteorologicalAgency, Lagos. Ricardian Model was used to analyze data. Annual rainfall effect on sorghum land value was negative and significantly different from zero at 10% level of probability; average temperature had positive effect on sorghum land value. We found positive future Climate change effects on sorghum under all climate scenarios for years 2020, 2060, and 2100.However, highest, and lowest economic gains from sorghum were 3143% under HADCM3 Climate Scenario for year 2060, and 111.88% under PCM, scenarios for year 2020 respectively. There is need for increased investment on farm technology, particularly, improved v arieties, with proven adaptation to high hydrological conditions.
