Climate smart agriculture practices by crop farmers: Evidence from south east Nigeria

Climate change has severely impacted African countries, particularly Nigeria, affecting farmers' productivity due to adverse weather conditions. Climate Smart Agriculture (CSA) has emerged as a crucial approach to ensure sustainable agricultural growth and food security. This study aims to identify the sources of awareness, prevalent innovative agricultural practices, determinants of CSA adoption, and the intensity of CSA practices among crop farmers in Southeast Nigeria. A two-stage multi-random sampling technique was employed to collect data from 270 farmers across various locations in Southeast Nigeria through questionnaires. The analysis used descriptive statistics and Heckman's two-stage selection model to evaluate the sources of awareness, the extent of CSA practice, and factors influencing CSA adoption and its intensity. Results indicate that cooperative societies and extension workers are the primary sources of CSA awareness in the region. Key determinants of CSA adoption identified in the study include gender, household size, farming experience, education level, labor force size, income, extension exposure, credit access, risk orientation, and cooperative membership. The Heckman model revealed that cooperative membership significantly increases the probability of CSA adoption, while risk-averse farmers are less likely to adopt CSA practices. The study concludes that while CSA practices are recognized and adopted to some extent, their implementation is insufficient to comprehensively combat the effects of climate change. Enhanced efforts to promote and integrate CSA practices more widely are critically needed. To improve CSA adoption and effectiveness, it is recommended to provide increased support for cooperative societies and extension services, better access to credit, and targeted education and training programs for farmers. Additionally, policies should focus on reducing risk aversion among farmers by providing insurance schemes and other risk management tools.
