Under UNFCCC guidance, it was decided that the LDCF would provide support, as a first step, for the preparation and implementation of NAPAs. The GEF, with the assistance of its implementing agencies, UNDP, UNEP and the World Bank, has already supplied funds for preparing NAPAs. The rationale for establishing the LDCF lies in the low capacity and high vulnerability of LDCs, which render them in need of immediate and urgent support in starting to adapt to current and projected adverse effects of climate change.
