Usage of Agroecological Climate-Smart Agriculture Practices among Sorghum and Maize Smallholder Farmers in Semi-Arid Areas in Tanzania
Abstract
Climate change variability and its impact on agricultural production in sub-Saharan Africa pose a significant challenge to food security. In Tanzania's semi-arid regions, there is growing concern regarding the use of agroecological Climate-Smart Agriculture (CSA) practices by smallholder farmers that adhere to agroecological principles. This study aimed to investigate the use of agroecological CSA practices among smallholder farmers in Tanzania's semi-arid regions, specifically in Dodoma and Tabora regions. In addition, this study sought to identify the key factors influencing the use of these practices to enhance food security, income, and climate resilience. Data were collected from 299 households in Dodoma and Tabora using various methods including questionnaire surveys, focus group discussions, and key informant interviews. Binary logistic regression was used to analyse factors influencing the usage of agroecological climate-smart agriculture practices. The findings revealed that most households in the study area use agroecological CSA practices. These practices include cereal-legume intercropping, mixed cropping, crop residue retention, crop rotation, and improved seed variety. Water harvesting, terraces, and cover crops were not used by many households. Several factors positively influenced the use of agroecological CSA. They include assistance from non-governmental organizations (NGOs), training in CSA practices, drought perception, access to credit, distance to market, membership in an organisation, education level of the household head, and total household income. To promote the use of agroecological CSA practices, both governments and NGOs should prioritise training programs. Moreover, providing frequent extension services and facilitating easier access to credit for farmers can further support the widespread use of these practices. In doing so, local communities can adapt better to the challenges of climate change, ensuring improved food security and climate resilience in the region
