Abstract

The African continent faces challenges from climate change, as manifested in the increasing atmospheric carbon dioxide concentrations and rising global temperatures, which pose significant threats to food security and agricultural productivity. Despite its minimal contributions to global greenhouse gas emissions, Africa is particularly susceptible to climate change, given its heavy reliance on rain-fed agriculture and limited adaptive capacity. Due to the evolving climatic conditions, research indicates substantial yield reductions in essential crops such as wheat, maize, sorghum, and millet. Furthermore, climate change is expected to alter soil fertility, compounding the challenges confronted by African nations in providing sustenance for their burgeoning populations. With the agriculture sector employing approximately 75% of the African population, the adverse effects of escalating temperatures and shifting rainfall patterns on net farm revenues imperil livelihood security. Given the limited resources and infrastructure accessible to small-scale farmers in the region, it is imperative to develop and implement resilience-building strategies that mitigate the repercussions of climate change on agriculture and food security in Africa.
