"Climate change has direct impact on agricultural production, because of the climate-dependent nature of agricultural systems. This impact is particularly significant in developing countries where agriculture constitute employment and income sources for the majority of the population. This project was aimed at promoting understanding of the most cost-effective and sustainable indigenous climate change adaptation practices in southeast Nigeria. The study was conducted in two randomly selected states of the region namely Imo and Enugu, and in four randomly selected agricultural zones, two from each state. The result of the analysis shows that In the face of extreme weather events occasioned by climate change, and apparently because of its tolerance to these conditions, cassava, has become the dominant food crop in the area. Virtually all the respondents reported that extreme weather events and uncertainties in the onset of farming season have been on the increase. In addition, they were also aware of the effect of climate change on agriculture, but were not aware that some agricultural practices could exacerbate climate change. The biggest effect of climate change in the region was reduced farm yield and income, drying up of streams/rivers, reduction in storage quality of crops, loss of pastureland/vegetation and destruction of wildlife ecosystem."
