The Assessments of Impacts and Adaptations to Climate Change (AIACC) program is a global initiative developed in collaboration with the Intergovernmental Panel on Climate Change and the United Nations Environment Programme/World Meteorological Organization and is funded by the Global Environment Facility.

By funding collaborative research, training and technical support, AIACC aims to enhance the scientific capacity of developing countries to assess climate change vulnerabilities and adaptations, and generate and communicate information useful for adaptation planning and action.

AIACC is implemented by the United Nations Environment Programme and executed jointly by the global change SysTem for Analysis, Research and Training (START) and the Third World Academy of Sciences (TWAS). In addition to the funding from the Global Environmental Facility, collateral funding has been provided by the United States Agency for International Development, the Canadian International Development Agency, the United States Environmental Protection Agency, and the World Bank.

AIACC has completed regional assessments throughout Africa, Asia, Latin America, and the Small Island States. Lessons gained around the issue of vulnerability from these assessments include: the urgency of climate change risks, the role of social and governance systems in dampening or amplifying vulnerability, impediments to development from water scarcity, worsening land degradation, threats to rural poor, vulnerabilities in coasts and small islands, risks to ecosystems and species, and human health risks.

Their regional assessments similarly highlight a series of adaptation lessons including: adapt now, adaptation is development, adaptation is for ourselves, international financial help is necessary, strengthen institutions, involve those at risk, expand information and awareness, and adaptation is place-based.

The draft final report of the AIACC project “Climate Change Vulnerability and Adaptation in Developing Country Regions” has been released.The $9 million, 5 year report covers 24 case studies of adaptation in developing nations.Some of the case studies include: adaptations to climate change that are working successfully for farmers in the Sudan and China, flood-prone cities in Argentina and Uruguay, and Caribbean islands at risk of dengue fever.
