Climate change does not respect national boundaries. It affects virtually every corner of the globe regardless of a country’s greenhouse gas emissions, or its capacity to deal with the effects of climate change.

Often neighbouring countries that share a common geography, such as a river basin, face similar climate change challenges, such as the Lower Mekong Basin. In regions such as the Pacific, Caribbean or Indian Ocean, where a number of small island states face similar climate change issues, their intrinsic features (size, fragile economies, exposure to natural hazards, etc.) make them ill-equipped to deal with challenges individually.

Many partner countries supported by the GCCA+ flagship initiative also belong to regional organisations that already have programmes to tackle climate change.
Building partnerships and ensuring complementarity underpin the work of the GCCA+, and for these reasons the GCCA+ supports regional or multi-country programmes to complement existing country interventions.

GCCA-supported programmes on the African continent are delivered through a number of existing organisations that seek common development objectives for their member countries. These include the Common Market for Eastern and Southern Africa (COMESA). In West Africa, the partner organisations are the Economic Community of West African States (ECOWAS), and the ‘Comité permanent Inter-Etats de Lutte contre la Sécheresse dans le Sahel’ (CILSS). The GCCA is also working with the African Union on continent-wide initiatives.

In the Pacific, the GCCA+ initiative works with the University of the South Pacific, the Secretariat of the Pacific Community (SPC) and the Secretariat of the Pacific Regional Environment Programme (SPREP) across various Pacific states. In the Western Indian Ocean, collaboration is recurrent with the Indian Ocean Commission as a regional partner for its insular members. In the Caribbean region, the GCCA+ has been supporting the 17 member countries of the Caribbean Forum (CARIFORUM) through the Caribbean Community Climate Change Centre (CCCCC) and the Organisation of Eastern Caribbean States (OECS); whilst in south-east Asia, the GCCA+ has been supporting the Mekong River Commission’s (MRC) Climate Change and Adaptation Initiative (CCAI).

The Local Climate Adaptive Living Facility (LoCAL) implemented by the United Nations Capital Development Fund (UNCDF) and funded by multiple donors, is a good illustration of a multi-country programme. In this specific case, implementation methodologies and tools link countries from Asia, Africa and the Pacific under the same programme.
