Implications of climate-smart strategy adoption by farm households for food security in Tanzania

In the light of climate change, farmers especially in developing countries adopt strategies to sustain their food production. The objectives of this paper are therefore to identify adaptation strategies in response to climatic changes and the determinants for their adoption, and to explore the impact of these strategies on food security. The analysis is based on a survey of 900 small-scale farmers in a semi-arid and a semi-humid region in rural Tanzania. The results show that farmers in the semi-humid region tend to diversify their crops. Given the more challenging environment in the semi-arid region, farmers there rather shift their crop portfolio, i.e. substituting some crops or cultivars with others. Logistic regressions highlight higher risk tolerance, land ownership, education or experiences of farmers as drivers of adoption, while income diversification has a negative effect. The propensity score matching approach shows that adopters of climate-smart strategies are on average more food secure. The adopters show a more diverse food consumption, more protein intake and better economic access to food. Shifting the crop portfolio appears to be the best performing strategy, especially in terms of more stable food provisioning throughout the year, which prevents the household from coping with climate-related shocks such as droughts.
