Abstract
Climate change (global warming) is often influence temperature and rainfall, which will directly have effects on the productivity and hence the net revenues of crops. This study was carried out to assess the impacts of climate changes (rainfall and temperature) on the net revenue for sorghum and millet crops in North Kordofan state environment, Sudan, during the period 1990-2012 using the Ricardian model. The results revealed that the elasticities to change in maximum temperature, minimum temperature and standardized rainfall for sorghum net revenue are: -1349.37, -598.098, -60.8788 respectively and for millet net revenue are: 2602.7, 258.1875 and 207.0783 respectively. The net revenues for both crops decreasing at increasing rate when there are increasing in maximum temperature. In case of minimum temperature, millet net revenue increase at increasing rate where sorghum net revenue increase at decreasing rate.
