1. Background
The Least Developed Countries Expert Group (LEG) was established in 2001 to provide technical guidance and support to the least developed countries (LDCs) on the process to formulate and implement national adaptation plans (NAPs) and the implementation of the LDC work programme. The LEG is also mandated to provide technical guidance and advice on accessing funding from the Green Climate Fund (GCF) to support the formulation and implementation of NAPs, in collaboration with the GCF secretariat, as well as on several other areas including strengthening gender considerations in NAPs.
The LEG is mandated to engage a wide range of organizations in implementing its work programme. Consequently, as a way to maximize the effectiveness of the support from the different organizations, the LEG established the NAP technical working group comprising of experts and representatives from organizations, regional centres and networks that provide technical support to developing countries on the process to formulate and implement NAPs, as well as other individual experts.
COP 26 invited the LEG to consider under its workplan the possibility of creating, as needed, thematic working groups to expand its technical support in specific areas, building on the experience and success of the NAP technical working group and taking into account the ongoing workload of the Group and its available resources (Decision 15/CP.26, paragraph 9).
2. Purpose
The NAP technical working group brings together diverse experts and support providers on NAPs to design possible modalities on how to jointly advance technical work on the process to formulate and implement NAPs, with a goal to promoting coherence and synergies, ensuring that countries will have the optimum benefit of the available technical assistance and support.
3. Subgroups
LEG 42 established four subgroups of the NAP technical working group, under the oversight of the LEG, on:
a) NAP technical guidelines, to support work on technical guidelines (and related supplements) for the formulation of NAPs, data access issues and use of scenarios in adaptation planning;
b) NAP implementation support, to support work on the technical guidelines and advice for the implementation of NAPs, accessing funding from the GCF and other sources, capturing and sharing best practices and lessons learned in developing and scaling up adaptation projects, and cataloguing priority project ideas from the LDCs;
c) NAP tracking, to support work on tracking and monitoring progress in formulating and implementing NAPs, methodologies for measuring outcomes and impacts of adaptation, and capturing broad best practices and lessons learned in adaptation through NAPs;
d) Multi-stakeholder forums, to support work on enhancing engagement and activities in the area of NAPs related to gender, youth, the private sector, national and subnational authorities, and local communities and Indigenous Peoples.
4. Reporting
The progress of work of the NAP technical working and the subgroups is captured in LEG reports and related documents.
