The document explores the application of Robust Decision Making (RDM) to address the 'super wicked' problem of climate adaptation in the Greater Mekong Subregion, where decision-making is often hindered by mistrust of national governments and unequal power dynamics. It suggests that while full RDM is technically intensive, a simplified 'RDM lite' approach could better suit local needs by preserving core principles of participation and robustness. The study also identifies critical needs for capacity building, strengthening informal networks, and ensuring 'meaningful' participation through transparent information access and digital inclusion.

The report examines the failures of water privatisation in Europe, citing infrastructure decay and high profits in the UK and France, while highlighting successful re-municipalisation in Paris and public resistance in Greece, Ireland, and Italy. It advocates for public ownership and cross-border cooperation to manage water as a public security issue and a public good, rather than a commodity, to effectively adapt to climate change.

The 2022 rainy season in West Africa saw above-average rainfall and devastating floods, particularly in Nigeria and Niger, where fatalities reached at least 612 and 195 respectively. An attribution study found that climate change made the seasonal rainfall over the Lake Chad region approximately 80 times more likely and 20% more intense, while the 7-day maximum rainfall over the lower Niger Basin became about twice as likely and 5% more intense. Beyond climate change, the flooding was driven by the release of the Lagdo Dam in Cameroon and exacerbated by high poverty rates, political instability, and the location of infrastructure and settlements on flood plains.

The study uses a Water Evaluation and Planning (WEAP) model and five CMIP5 GCMs to project climate impacts on the Sittaung river basin. Findings indicate that while increased riverine flows will likely benefit domestic water supply and hydropower generation, unmet agricultural demands for food production are expected to increase.

The report examines how climate change acts as a risk multiplier in Mainland Southeast Asia, specifically Burma, Cambodia, Laos, Thailand, and Vietnam. It identifies state governance capacity and social and economic inequality as the primary drivers of regional insecurity. Through four scenarios—ranging from 'Paralyzed States, Vulnerable Populations' to 'Building Resilience, Strengthening Communities'—the analysis explores how these drivers influence outcomes like food insecurity, forced migration, and the proliferation of criminal networks. The document recommends that external stakeholders support policies to reduce inequality, engage regional security services for cooperation, and utilize ASEAN as a platform for climate risk mitigation to navigate the geopolitical tensions between the U.S. and China.

Haiti has launched its first National Adaptation Plan (NAP) for 20222030, focusing on agriculture, water, health, and infrastructure. The plan identifies 340 adaptation actions, with 21 designated as priority actions requiring a minimum of USD 980 million in funding. Implementation depends on strengthening human capacities, adopting climate technologies, and establishing a monitoring, evaluation, and learning (MEL) system. The document stresses that inclusive governance involving universities, the private sector, civil society, and local governments is essential for success, with a specific focus on gender mainstreaming and the role of the National Committee on Climate Change (CNCC).

The document examines the gap between scientific recognition of transboundary climate risks and the current local focus of multilateral adaptation finance. It proposes a shift toward 'systemic resilience' to address risks that cross borders via shared ecosystems, trade, and financial flows.

The Upper Rio Grande Basin is in moderate condition with an overall score of 54% (C), facing severe threats from climate change, drought, and population pressure. While municipal water supplies remain strong, annual low flows are critically low, and the river's natural hydrology is heavily altered, particularly in southern New Mexico and Texas. Scenario modeling indicates that rising temperatures and declining precipitation will further reduce water availability for agriculture and ecological flows by 2050. Proposed mitigation strategies include reducing irrigation losses, fallowing agricultural land, and reducing municipal water demand to restore environmental flows.

The Gender Action Plan for the SAP025 project in northwest Guinea-Bissau aims to reduce gender inequality by prioritizing women, who will make up 70% of the target beneficiaries. The plan focuses on increasing women's participation in farmers' clubs, improving access to literacy and income-generation education, and addressing time-poverty through the establishment of community childcare systems. To ensure implementation, the project will employ a gender specialist to oversee activities, provide quarterly training for staff, and review materials for gender sensitivity. The project is structured around three outcomes: strengthening climate risk monitoring, adapting water management, and enhancing the resilience of smallholder agricultural systems, all of which include specific targets for female participation in leadership and decision-making. Monitoring will involve sex-disaggregated data and the tracking of specific vulnerable sub-groups of women, such as widows, heads of households, and those with disabilities.

The document argues that nature-based solutions (NbS) often fail to achieve their potential because planning ignores the complexities of scale. It highlights that NbS have longer time-lags than grey infrastructure, spatial dependencies that transcend individual sites, and jurisdictional barriers that complicate governance. The authors recommend a shift toward quantitative targets, 'no regrets' strategies, and cross-jurisdictional coordination to avoid large-scale maladaptation.

The study compares the Integrated MultisatellitE Retrievals for- Global Precipitation Measurement (IMERG) and Climate Forecast and System Reanalysis (CFSR) products against approximately 50,000 in-situ surface stations globally. The results indicate that IMERG generally outperforms CFSR in simulating monthly rainfall across most regions, continents, and countries. Specifically, IMERG showed significantly better mean Nash-Sutcliffe Efficiency (NSE) in 64 countries. While CFSR provided satisfactory simulations for Europe, North America, and Australia, it was unsatisfactory for other continents. To facilitate the use of high-quality data for hydrologic modelling, the authors introduced the Worldwide Weather Service (W3S) for the preprocessing and dissemination of IMERG precipitation data.

The Mijares River basin faces significant environmental threats, including a 56% reduction in summer storms since 1950 and high risks of desertification and forest fires. To address these, the document proposes five targeted adaptation measures: recovering extensive grazing in the headwaters, creating mosaic landscapes, restoring traditional orchards in the upper and middle reaches, maintaining rain-fed crops in the middle reach, and diversifying citrus plantations with sustainable woody crops in the lower reach. Implementation is hindered by fragmented private land ownership (minifundios), rugged terrain, and the loss of traditional knowledge. The brief advocates for a participatory, integrated territorial approach involving payments for ecosystem services and the integration of women and youth into rural employment.

The report analyzes the alignment between three voluntary sustainability standards (VSSs)—the East African Organic Products Standard (EAOPS), the Sustainable Rice Platform (SRP) Standard, and GLOBALG.A.P.—and the agricultural policies of the East African Community (EAC). It focuses on staple crops (beans, maize, rice, and wheat) which are critical for food security and regional trade. The findings indicate strong alignment with climate resilience goals and medium alignment with productivity and trade objectives. Key barriers to scaling VSSs include high certification costs for smallholders, low domestic demand for certified products, and a lack of official political recognition from national standards bureaus. The report recommends that VSS bodies use pilot projects to prove their value and that EAC policy-makers provide targeted financial support and official recognition to integrate these standards into regional trade and development frameworks.

The report provides a comprehensive strategic and programmatic framework for the Tupiza River Basin, focusing on improving water security, sanitation, and climate resilience. It identifies critical vulnerabilities, including mining-related water contamination, inadequate sanitation in rural areas, and high susceptibility to floods and frosts. The plan proposes specific infrastructure investments—such as rainwater harvesting tanks, deep wells, and decentralized wastewater treatment plants—alongside gender-focused empowerment programs and sustainable mining management to mitigate environmental degradation.

The report details a comprehensive water management plan for the Pampa Huari Basin, utilizing a Robust Decision Support (ADR) framework to address vulnerabilities in water quality, quantity, and sanitation. It identifies critical pressures from mining and climate change, proposing five strategic lines of action including ecosystem restoration, sustainable water supply, irrigation modernization, mining impact mitigation, and institutional strengthening, with a total estimated investment of 145,537,813 Bs.

The Ouémé Basin Climate-Resilience Initiative (OCRI) is a six-year project in Benin designed to reduce climate vulnerability for 330,000 direct beneficiaries and 6 million indirect beneficiaries. The initiative focuses on the Upper and Middle Ouémé Basin, implementing a mix of hard infrastructure (micro-dams, water harvesting) and soft measures (climate-resilient agriculture, agroforestry) across 95,000 hectares. It targets key value chains including maize, cashew, shea, and mango to diversify income and reduce poverty. The project also establishes a multi-stakeholder platform to institutionalize integrated basin management and strengthens the financial capacity of the Fonds National pour l’Environnement (FNEC) to provide long-term climate finance.

The document examines the process and impact of an economic study in Uganda that found the cost of inaction on climate change to be 20–24 times higher than the cost of adaptation. This evidence facilitated the integration of climate change into national development plans (NDP II and NDP III), the elevation of the Climate Change Unit to a Department, and the passage of the National Climate Change Act 2021. Key success factors included continuous engagement with high-level leadership, an in-country presence, and the use of layered communication products like documentary films. However, challenges remain in sub-national implementation and the lack of dedicated climate budget lines in the national budgeting system.

The document outlines a proposed constitutional framework for Chile that integrates ecological principles with human rights. It highlights specific articles that establish the rights of nature, the right to a healthy environment, and the state's obligation to mitigate climate risks. Additionally, it details the proposed creation of a National Water Agency and a Nature Defender's office to ensure sustainable resource management and environmental justice.

The Somali National Adaptation Plan (NAP) process, led by the Ministry of Environment and Climate Change, utilizes a participatory and gender-responsive approach aligned with peacebuilding. The process is currently supported by a Green Climate Fund-funded NAP Readiness Project implemented by the UNDP. Key adaptation priorities include sectors such as agriculture, water, health, and coastal zones, addressing impacts like severe droughts, flooding, and sea level rise. Significant milestones between 2018 and 2022 include the launch of the National Disaster Management Policy, the National Climate Change Policy, and the 2021 NAP Framework.

The document examines the challenges African countries face in accessing sustainable finance for regional infrastructure, noting a significant financing deficit and a lack of bankable projects. It highlights the disparity between climate mitigation and adaptation finance, arguing that adaptation is more critical for Africa's vulnerability. The brief analyzes the ASEAN regional approach—specifically its sustainability taxonomies and the ASEAN Catalytic Green Finance Facility—as a model for Africa. It evaluates current AU initiatives, such as the Alliance for Green Infrastructure in Africa and the Green Infrastructure Corridor for Intra-African Trade, and recommends integrating sustainability more deeply into AfCFTA protocols to attract investment and enhance climate resilience.
