Agricultural extension as a pathway to livelihood diversification and sustainable development in rural communities: a systematic review

Abstract

Farming communities in the Global South face a range of challenges, such as climate variability, pests and policy changes, which threaten agricultural productivity and livelihood diversification. Agricultural extension services provide a crucial pathway to address these challenges by enhancing agricultural production, income, resource management and partnerships, all of which are important for alleviating rural poverty. However, the role of agricultural extension in supporting livelihood diversification and reducing rural poverty remains underexplored in the literature. This review aims to evaluate the contribution of agricultural extension to livelihood diversification strategies and rural poverty reduction by facilitating access to livelihood capitals. A systematic review method was conducted to identify studies published between 2014 and 2024. The search was performed across several academic databases using predefined Boolean Operator search terms related to agricultural extension and livelihood diversification. Out of the 163 identified documents, 36 duplicates were eliminated, and 127 underwent priority screening, leaving 76 documents for full-text review. Consequently, 45 studies met the inclusion criteria. Descriptive statistics were used to summarize study characteristics, while qualitative thematic analysis was applied to identify recurring themes and gaps of extension approaches in supporting livelihood diversification. The findings highlight the pivotal role of agricultural extension in reducing rural poverty and supporting livelihood diversification by improving access to human, social, physical, financial and natural resources. For example, by providing platforms for partnerships with financial institutions, rural families have gained access to microcredit, empowering them to invest in both farm and nonfarm activities. Additionally, digitally driven extension services have increased youth’s and women’s participation in agricultural and off-farm economic activities. Despite the positive contributions of agricultural extension services, challenges such as insufficient gender-responsive training programs, inadequate financial resources and limited nonfarm employment opportunities continue to hinder livelihood diversification strategies. This study underscores the need for an integrated approach that connects both farm and nonfarm opportunities with financial literacy programs and gender-responsive capacity-building initiatives tailored to the needs of rural communities. Policy interventions should prioritize strengthening access to financial services and inclusive agricultural extension programs to enhance rural livelihood diversification strategies and poverty reduction for sustainable development.
