The geographical condition of Wonogiri Regency is agro climatically suitable for the cultivation of cassava. The management of cassava cultivation certainly has risks that can occur from natural factors, such as climate, weather, floods, as well as pests and diseases, during the cultivation process, price risks, etc., and ultimately will have an impact on farmers’ income. Cassava risk analysis due to climate change is an interesting topic to research because it can cause huge losses that affect farmers’ incomes and income inequality of cassava farmers. The study aims to (1) identifies the impact of climate change on cassava farming, (2) analyze the income of cassava farmers as a result of climate change, (2) analyze the risks of cassava farming from the impacts of climate change. The research method used is a survey with purposive sampling in the determination of sub-districts and villages, selected Ngadirojo Subdistrict, cassava farmers took 60 farmers in simple random sampling. Data were analyzed with descriptive analysis, frequency analysis, revenue analysis, and risk analysis. The results showed that there was a 12.43% change in income due to climate change as measured by the delay in the growing season and product quality. There is a change in quality and quantity in three types of cassava market in Wonogiri Regency, namely (1) wet cassava market, (2) dry cassava market (gaplek ), (3) industrial market that goes directly into the factory. Risk analysis obtained coefficient of variation (CV) of 0.503 which means that the average income risk faced by farmers is classified as risky in the low category (CV>0.5), with the lower limit value (La) showing Rp. 28,121.82 which means that in running a cassava cultivation business, farmers must dare to bear the risk of income of Rp. 28,121.82 (12.47%) in one period of cultivation.
