Climate change exacerbates conflicts in vulnerable regions, particularly arid and semi-arid pastoral areas and across borders. Rising temperatures, erratic rainfall, and extreme weather accelerate rangeland degradation, deforestation, and water scarcity, leading to food and resource shortages that drive migration and violent conflicts. Increased global resource competition further heightens international tensions. In the Horn of Africa, drought has affected 36.4 million people, causing widespread crop failure and livestock deaths, with Ethiopia alone losing 6.85 million livestock since 2021. The economic toll is severe, especially for pastoralist communities reliant on animal products. Women and children are disproportionately affected, necessitating targeted interventions. Climate change also threatens Ethiopia’s coffee industry, a key export sector, with projections showing a 60% decline in suitable areas for Arabica coffee cultivation by 2050. Additionally, climate change has shifted species’ ecological ranges, enabling invasive species like Prosopis juliflora to spread, harming pastoral livelihoods and biodiversity. By 2050, highly suitable areas for its invasion are expected to expand by 63.6%. Urgent climate action is required to mitigate these risks. This review calls for early warning systems, environmental risk assessment mechanisms, livelihood diversification, improved resource management, and resilience-building to reduce conflicts and promote sustainability.

摘要

Climate change exacerbates conflicts in vulnerable regions, particularly arid and semi-arid pastoral areas and across borders. Rising temperatures, erratic rainfall, and extreme weather accelerate rangeland degradation, deforestation, and water scarcity, leading to food and resource shortages that drive migration and violent conflicts. Increased global resource competition further heightens international tensions. In the Horn of Africa, drought has affected 36.4 million people, causing widespread crop failure and livestock deaths, with Ethiopia alone losing 6.85 million livestock since 2021. The economic toll is severe, especially for pastoralist communities reliant on animal products. Women and children are disproportionately affected, necessitating targeted interventions. Climate change also threatens Ethiopia’s coffee industry, a key export sector, with projections showing a 60% decline in suitable areas for Arabica coffee cultivation by 2050. Additionally, climate change has shifted species’ ecological ranges, enabling invasive species like Prosopis juliflora to spread, harming pastoral livelihoods and biodiversity. By 2050, highly suitable areas for its invasion are expected to expand by 63.6%. Urgent climate action is required to mitigate these risks. This review calls for early warning systems, environmental risk assessment mechanisms, livelihood diversification, improved resource management, and resilience-building to reduce conflicts and promote sustainability.
