Climate change presents formidable obstacles for nations in the Global South, touching every aspect of life—from environmental stability to economic resilience and public health.
These countries face heightened risks due to a mix of factors including their geographic exposure, socio-economic vulnerabilities, and limited resources for adaptation.
Nations in the Global South are especially prone to severe weather events like floods, droughts, cyclones, and heatwaves. These climate-related disasters can wreak havoc on infrastructure, damage homes and farmland, and disrupt communities. Unpredictable rainfall and temperature shifts are also taking a toll on agriculture—threatening food security and undermining livelihoods in regions where farming remains a primary source of income.
In many areas, water scarcity is intensifying due to climate-related changes, making it harder to secure clean water for domestic, agricultural, and industrial use. Coastal communities, in particular, face the added threats of rising sea levels, leading to flooding, saltwater contamination, and displacement.
Public health is another critical concern. Warming temperatures and changing ecosystems are contributing to the spread of diseases carried by vectors, such as malaria and dengue fever. Heat stress and other climate-related health risks disproportionately affect the most vulnerable populations.
The Global South is also rich in biodiversity, yet climate change is destabilizing ecosystems and threatening species that local communities depend on for food, medicine, and livelihoods. These ecological disruptions have broader implications for both human welfare and environmental sustainability.
Displacement and migration triggered by climate-related disasters are growing trends. As people are forced to leave their homes due to floods or failed crops, the struggle to rebuild lives and secure stable futures in unfamiliar areas intensifies.
Economically, climate change threatens to derail development by disrupting key sectors like agriculture, fishing, and tourism. At the same time, recovery efforts and investments in adaptation stretch already limited public finances.
Despite contributing minimally to global greenhouse gas emissions, the Global South bears a disproportionate share of the climate crisis. Wealthier nations—primarily in the Global North—have driven much of the pollution that has created this emergency. While financial support for adaptation and mitigation is often pledged, delivery remains inconsistent and inadequate.
To address these challenges, countries in the Global South need not only funding but also stronger institutional frameworks, technological capabilities, and human capital to effectively absorb and utilize climate finance. Building this capacity is essential to developing climate resilience and ensuring inclusive, sustainable growth in the face of a rapidly changing planet.
