This briefing from the Stockholm Environment Institute (SEI) describes the Water Evaluation and Adaptation Planning (WEAP) platform, a scenario-based modelling tool designed to help decision-makers understand climate impacts on water systems and develop adaptation strategies. It highlights WEAP's role in supporting National Adaptation Plans (NAPs) and provides examples of its application in various global regions to manage water scarcity, resource allocation, and transboundary river basins.

This policy brief by the South African Institute of International Affairs outlines priorities for Africa's adaptation finance under the South African G20 presidency. It highlights a severe funding gap, where Africa requires $187–359 billion annually but faces an 80% shortfall in adaptation investment. The document advocates for a shift from debt-creating loans to grant-based and concessional finance, leveraging G20 working groups and MDB reforms to support National Adaptation Plans (NAPs) and locally led adaptation.

This report reviews 59 multi-sector national adaptation plan (NAP) documents to analyze how developing countries address adaptation finance, identifying good practices and areas for improvement in the identification, prioritization, and mobilization of funds.

This report examines the integration of climate-related human mobility—including migration, displacement, and planned relocation—into national and sub-national adaptation planning and governance, utilizing case studies from Costa Rica, Senegal, and Sri Lanka.

This research paper by the Stockholm Environment Institute argues for the urgent integration of sanitation considerations into national climate policies and the inclusion of climate adaptation and mitigation measures within sanitation policies.

This analysis by the NAP Global Network emphasizes the importance of progress reporting in National Adaptation Plan (NAP) processes. It argues that reporting facilitates a "learn-by-doing" approach to monitoring and evaluation, enhances transparency and accountability, and supports the implementation of the Paris Agreement. Despite these benefits, the report notes that few countries currently track NAP progress due to resource and capacity constraints.

This policy brief examines the vulnerability of Africa to transboundary and cascading climate risks, where climate impacts in one country affect others through trade, finance, migration, and shared ecosystems. It discusses the role of National Adaptation Plans (NAPs) in managing these risks and provides recommendations for the African Group of Negotiators (AGN) to seek support via UNFCCC processes.

This briefing explores country perspectives on aligning national-level policy processes under the Paris Agreement, specifically National Adaptation Plans (NAPs) and Nationally Determined Contributions (NDCs), to foster broader climate-resilient development.

This consultation draft policy brief by the Stockholm Environment Institute examines climate hazards affecting the agriculture and water sectors in the Greater Mekong Subregion (GMS). It analyzes the status of National Adaptation Plans (NAPs), identifies critical climate risks such as heatwaves and flooding, and outlines priority adaptation strategies and financing gaps across the region's member states.

This April 2018 briefing by the Stockholm Environment Institute, IDDRI, and ODI argues that climate adaptation is currently undervalued in international negotiations because it is viewed as a local problem. The authors advocate for a 'transboundary' framing of climate risk to address the interconnections between people, ecosystems, and economies in a globalised world, suggesting that the UNFCCC and the Paris Agreement provide the necessary tools to move toward a coordinated global adaptation response.

This research paper by the World Resources Institute proposes the BLUE framework to help countries integrate blue carbon ecosystems—specifically mangroves, tidal marshes, and seagrasses—into national climate strategies such as Nationally Determined Contributions (NDCs) and National Adaptation Plans (NAPs) to overcome data and institutional barriers.
