Implications of a Climate-Smart Approach to Food and Income Security for Urban Sub-Saharan Africa: A Systematic Review

Abstract

Climate change presents a significant threat to humanity. It affects agriculture, food supply, and economic development. Urban agriculture (UA) is an alternate climate-smart approach to enhancing food and income security. The climate-smart agriculture (CSA) concept promises to lessen the effects of climate change. Nuanced research is critical to warrant food and income security. This review paper synthesises evidence through a systematic literature search to analyse the implications of CSA practices and climate adaptation strategies for food and income prospects. We also employed bibliometric analysis to show emerging trends and identify knowledge gaps in the ongoing topical discourse. The review elucidates insights into how CSA practices boost urban food production, accessibility, and dietary diversity, ultimately enhancing urban farmers’ food security. The economic benefits of CSA and climate adaptation strategies highlight that UA is vital for improving urban farmers’ income. Despite the opportunities created by UA, the review recognises the critical challenges and trade-offs that call for transforming UA to safeguard food and income security in the face of increasing climate change. The review calls for an all-round UA transformation encompassing urban community-based efforts, capacity building, and policy support mechanisms aimed at advancing climate-resilient UA and ensuring food and income security in an ever-changing environment.

Assessing Agricultural Impact on Greenhouse Gases in the European Union: A Climate-Smart Agriculture Perspective

“…The empirical study findings are in line with the perspective of Khumalo et al [96], according to whom CSA has a profound impact on how agriculture adapts to climate change and manages associated risks. Promoting sustainable agricultural practices and innovative technologies, CSA can enhance farmers' adaptability to extreme weather conditions and contribute to reducing GHG in the agricultural sector [96]. This finding has significant implications for food security and global sustainability, as it helps protect natural resources and improve the resilience of food systems to impending climate change.…”

“…These findings are consistent with previous research, such as that of Mizik [6], which has shown that agricultural production can be an essential factor in determining GHG. Moreover, Khumalo et al [96] have emphasized that CSA can have a significant impact on GHG, suggesting that more efficient and innovative agricultural practices could contribute to their reduction. The empirical study findings are in line with the perspective of Khumalo et al [96], according to whom CSA has a profound impact on how agriculture adapts to climate change and manages associated risks.…”
