The Climate Change Adaptation Unit produces a range of analyses to develop and boost National Adaptation Plans (NAPs). Originally conceived by the UNFCCC, these plans aim to understand climate risks, identify optimum adaptation activities, and subsequently integrate these into national policy and planning. Year after year, the UN Environment provides support to an increasing number of countries to coordinate their NAPs. This 'global support programme' offered to governments includes training packages, methods, and guidelines. There is also regular one-on-one country-level support.
Some of the UN Environment's analytic work used for NAPs includes: Area-specific modelling scenarios of climate impacts on socio-economic projections; national decision-support systems based on environmental indicators and maps; economic analytic products to underpin the selection of adaptation priorities; and the development of national adaptation targets.
The UN Environment has a track record of facilitating impact-assessments, often based on the DPSIR framework (drivers-pressures-state-impact-responses). These assessments have been influential on an international scale. The UN Environment develops a range of methodologies for vulnerability and climate impact-assessments (VIA), many of which are responses to specific demands from governments. Thus, decision-makers are led by the most expert scientific information.
