The AIACC Project Assessments of Impacts and Adaptations to Climate Change in Multiple Regions & Sectors AIACC Latin America/Caribbean Region Meeting San Jose, Costa Rica May 2003

AIACC Objectives l Advance scientific understanding l Of climate change I, A & V in developing country regions. l Build and enhance scientific & technical capacity in developing countries l To investigate I, A & V and l To participate in international scientific assessments (e.g. IPCC, MA) l Contribute to National Communications, NAPAs and adaptation planning

AIACC Partners AIACC is a partnership among GEF, UNEP, START, TWAS, IPCC, and developing country institutions –GEF provides the principal funding –UNEP is the implementing agency –START and TWAS are the executing agencies –Participating institutions in developing countries have provided collateral funding –Additional funding comes from USAID, USEPA, CIDA and World Bank

Means to achieving objectives Fund regional research projects Provide training and mentoring Engage stakeholders in the project Link with National Communications Establish a network of scientists and stakeholders to endure beyond the AIACC project

AIACC studies active in 46 developing countries 24 regional studies funded Each study involves a team of scientists from multiple disciplines –235+ scientists from developing countries participating as investigators –60+ graduate and undergraduate students –40+ scientists from developed countries collaborating

Stakeholders, Nat’l Communications, Networks AIACC engages stakeholders –For input to objectives, approaches, evaluation of adaptations, review of outputs AIACC links with National Communications –Each regional study making contact with relevant ministries, committees, persons AIACC builds networks –Through participation in studies, workshops, “discuss aiacc” list- serve, and web-based database and information network

Commonalities among regional studies Most are interested in –Near-term consequences of climate change for people –Interactions with other stresses or threats –Human and social aspects of vulnerability –Response strategies (i.e. adaptation) that would lessen risks from climate change AND address other more immediate threats Has led many AIACC studies to take a “2nd Generation” approach to assessment

2nd-Generation Assessments Emphasize understanding human side of vulnerabilities –Who is vulnerable to harm? From what? Why? Explore multiple, interacting stresses –Climate change, extreme weather, population growth, land use change, urbanization, land degradation... Evaluate responses, adaptations –Focus responses on causes of vulnerability Engage stakeholders –Enhance relevance, utility, credibility

Anticipated outcomes Advance science –Publication of peer reviewed papers, thematic reports that expand literature on developing country I, A and V –Citation of AIACC findings in IPCC & MA reports Build capacity –Participants continue their research and link to policy –Increased numbers of developing country researchers engaged in IPCC, global change research Contribute to National Communications –AIACC participants collaborate in preparation of Nat’l Communications –Use of AIACC findings in National Communicaitons
