Assessments of Impacts and Adaptation to Climate Change (AIACC)

The AIACC Project was completed in 2007.

Assessments of Impacts and Adaptations to Climate Change (AIACC) was a global initiative developed through between START, UNEP, the Academy of Sciences of the Developing World (TWAS) and the Intergovernmental Panel on Climate Change (IPCC), and funded by the Global Environment Facility (GEF), with collateral funding provided by the US Environmental Protection Agency, US Agency for International Development, World Bank and participating institutions in developing countries.

AIACC sought to advance scientific understanding of climate change vulnerabilities and adaptation options in developing countries. AIACC enhanced capacity in developing countries to assess climate change vulnerabilities and adaptations, and generate and communicate information useful for adaptation planning and action.

AIACC supported 24 regional study teams to conduct three-year investigations of climate change impacts, adaptation and vulnerability in 46 developing countries, and involved 235 developing country scientists and more than 60 graduate and undergraduate students. The research activities addressed a range of questions about vulnerabilities to climate change and multiple other stresses, their implications for human development, and policy options for responding.

The AIACC regional studies were diverse in their objectives, and scientific methods in the sectors and systems that were investigated. These included agriculture and food security, water resources, livelihood security, and human health.

Outcomes of AIACC:

  • Publication of peer-reviewed scientific articles by participating scientists that significantly expand understanding of developing country vulnerabilities and adaptation options
  • Increased numbers of developing country researchers, particularly young researchers, who are now actively engaged in global change research
  • Increased participation of developing country scientists in global assessments, such as the IPCC
  • Wider understanding of climate change issues among stakeholder groups in developing countries.
  • Use of information generated by AIACC studies in National Communications and for planning adaptation actions
