Determinants of farmers' choice of adaptation strategies against climate variability and change: Lessons from central Tanzania in Manyoni district

Farmers' adaptation strategies against climate variability and change impact are fundamental in abating the effects in this epoch. Previous studies have confirmed the presence of context-specific farmers' adaptation strategies in Tanzania. However, it is not clear what factors influence farmers to select specific adaptation strategies. This study contributes to filling this knowledge gap. We used the cross-sectional research design in a survey of a random sample of 330 small-scale farmers. The multivariate probit was used to model the factors determining the choice of adaptation strategies. Farmers adapted a number of strategies, nonetheless, there were four key adaptation strategies: drought-resistant varieties, use of early maturing varieties, resistant livestock breeds, and conservation agriculture. Farmers used more than one strategy, and the choice was determined by multiple factors that showed a statistically significant impact at 5 %. We categorize the factors into four groups: (i) individual farmer and or household characteristics covering age, farming experience of the household head; household size; and household wealth, especially livestock ownership (ii) farm characteristics like location of the farm and farm size (iii) institutional factors that include access to extension services, technology, and provision of title deeds for land ownership to the farmers; and (iv) knowledge of manifestation of CV & C like shifting of rain seasons, and awareness of using meteorological information in decision making. These factors should be considered in policy development to heighten the effectiveness of the adaptation strategies in cushioning climate variability and change impact in the study area and central Tanzania at large.
