الوصف: Climate Change and Cassava Processing in Southeast Nigeria. Climate change is perhaps the most serious environmental threat to whom African agriculture is confronted today, essentially because of its impact on pre- and post-harvest agricultural productivity. Available literature shows that most of the recent studies on climate change and agriculture were mainly focused on pre-harvest, with little or no emphasis on post-harvest issues. This study aims to provide empirical information on the effect of climate change on cassava processing and on the cost-effectiveness of indigenous adaptation practices relative thereto. The study was conducted in two randomly selected states of southeast Nigeria and in four randomly selected agricultural zones, two from each state. The data were collected using a well-structured questionnaire administered to 320 randomly selected cassava processors. The result of the analysis shows that the respondents were predominantly women who, in addition to cassava processing, also grow cassava. Virtually all of them were, not only aware of climate change, but also aware that it will have effects on cassava post-harvest operations. The respondents suggest that as a result of climate change, the length of time cassava tubers can stay in the soil without spoiling has been decreasing while the water content of cassava tubers has been increasing. In addition, the storage quality of all the products has been deteriorating, just as the growth of spoilage moulds in the products during storage has been increasing. Moreover, the fermentation period for akpu and alibo has been increasing while there has been a general decline in the quantity of product yield after processing for all the products. Some of the adaptation measures used by the processors include increased use of water, palm oil, hired labour and wood fuel, increased harvesting of cassava earlier than usual, processing of more adaptive varieties of cassava, shifts in the timing of processing as the weather also shifts and increased fermentation in the open spaces. There were also some relatively new adaptation practices such as the use of detergents, nails, beans and bitter leaf to aid fermentation, especially for the production of akpu and alibo. In terms of profitability, the four adaptation practices with high profitability indices were, in order of decreasing importance, increased use of sundrying, water, hired labor and palm oil. The study therefore recommends that breeding of improved varieties of cassava should begin to target those that are tolerant to excessive and extreme fluctuations of rainfall, heat and flood. In addition, the adaptation practices with high profitability indices should be vigorously disseminated. Also, further studies, especially on the chemistry of the observed relatively new adaptation practices should be explored.
