Effects of climate change on small island countries
Résumé
The effect of climate change on small island countries can be extreme because of low-lying coasts, relatively small land masses, and exposure to extreme weather. The effects of climate change, particularly sea level rise and increasingly intense tropical cyclones, threaten the existence of many island countries, island peoples and their cultures, and will alter their ecosystems and natural environments. Several Small Island Developing States (SIDS) are among the most vulnerable nations to climate change.
Some small and low population islands are without adequate resources to protect their islands, inhabitants, and natural resources. In addition to the risks to human health, livelihoods, and inhabitable space, the pressure to leave islands is often barred by the inability to access the resources needed to relocate. The nations of the Caribbean, Pacific Islands and Maldives are already experiencing considerable impacts of climate change, making efforts to implement climate change adaptation a critical issue for them.
Efforts to combat these environmental changes are ongoing and multinational. Due to their vulnerability and limited contribution to greenhouse gas emissions, some island countries have made advocacy for global cooperation on climate change mitigation a key aspect of their foreign policy. Governments face a complex task when combining gray infrastructure with green infrastructure and nature-based solutions to help with disaster risk management in areas such as flood control, early warning systems, nature-based solutions, and integrated water resource management. As of March 2022, the Asian Development Bank has committed $3.62 billion to help small island developing states with climate change, transport, energy, and health projects.
Small Island Developing States make minimal contribution to global greenhouse gas emissions, with a combined total of less than 1%.
However, that does not indicate that greenhouse emissions are not produced at all, and it is recorded that the annual total greenhouse gas emissions from islands could range from 292.
