This study examines the impact of climate change on farming households in South Africa, using a profitability and utility framework to measure food insecurity within the agricultural sector. In light of various studies conducted to demonstrate the detrimental impacts of global warming within agricultural economics, we hypothesize that the consequences of a decrease in rainfall, an increase in temperature, and an increase in gas emission will substantially decrease agricultural yield over time. Using an OLS robust regression model, we empirically test this hypothesis using cross-sectional data on three crop varieties as the dependent variables, and their relationships with climatic and explanatory variables. Our results indicate that changes in rainfall, temperature, and land variables have significant impacts on agricultural production, although each crop type behaved differently according to their designated characteristics. Consistent with the hypothesis, the results show that an increase in temperature negatively impacts maize yield, and an increase in rainfall positively impact wheat and rice paddy yields.
