Abstract: Abstract The damaging effects of changing climate on farm-household food security are steadily increasing in sub-Saharan Africa. Adaptation strategies are important for agrarian households to reduce the adverse effects on their food security. This study employed multivariate probit and endogenous switching regression models to analyze the determinants of farm households’ choice of climate-change adaptation strategies, such as the cultivation of early maturing crops, early planting, growing drought-tolerant maize varieties, using precautionary savings, practicing income diversification, and sale of assets, and their effects on household food security in Tanzania. Information on expected rainfall and temperatures, early warning systems, previous droughts, delays in the onset of the rainy season, sex and age of the farmer, educational level, farming experience, family size, total farmland holding, number of livestock owned, contact with extension agents, and access to credit services were all found to influence decisions by farm households to use strategies of adaptation to climate change. Overall, the adaptation of farm households to climate change increased their food security status. An analysis of “adapter” and “non-adapter” farm households showed that the effect of adaptation on food security was smaller for households that adapted than for households that did not. Thus, we recommend that further effective adaptation strategies such as planting drought-resistant crops, changing planting dates, planting early maturing crops, and practicing income diversification be developed and used, particularly for the most vulnerable farm households, to mitigate the adverse impacts of climate change on their food security.
