The Nature4Cities Latam project is a 24-month readiness initiative designed to address barriers to the adoption of Nature-based Solutions (NbS) in six selected secondary cities across Cuba, Ecuador, Honduras, and the Dominican Republic. The project focuses on strengthening the knowledge base, reinforcing policy frameworks, fostering private sector partnerships, and developing innovative climate finance strategies. Key deliverables include city-level vulnerability and GHG assessments, Nature-Based Urban adaptation and mitigation Plans, and a regional online platform for knowledge sharing. The initiative aims to transition from pilot assessments to a pipeline of fundable project concept notes for the Green Climate Fund.

This research paper by the Climate and Development Knowledge Network (CDKN) identifies key strategies to accelerate climate change adaptation across Africa. Based on interviews with African scientists and practitioners, the paper advocates for a shift toward locally-led, inclusive solutions that integrate indigenous knowledge with scientific projections. It proposes three primary investment pillars: enhancing people's skills and knowledge, building climate-resilient economies, and investing in nature-based solutions.

The document outlines a strategic framework for accelerating climate adaptation in Africa, emphasizing the integration of indigenous knowledge with scientific data and the need for decentralized finance. It advocates for investing in a climate-smart workforce, resilient water and energy systems, and nature-based solutions to protect biodiversity and human livelihoods.

The Water Infrastructure Criteria under the Climate Bonds Standard provide a framework for certifying bonds that finance engineered, nature-based, or hybrid water infrastructure. To be eligible, assets must meet both mitigation and adaptation requirements. Mitigation is assessed based on net GHG emissions impact or, for desalination plants, a specific carbon intensity threshold of 100g CO2e/kWh. Adaptation and resilience are evaluated through a Vulnerability Assessment and Adaptation Plan, scored via a detailed scorecard covering allocation, governance, technical diagnostics, and specific requirements for nature-based solutions and desalination plants. The criteria exclude investments in fossil fuels, nuclear energy, mining, and water-driven energy like hydropower.

The document details the three-phase development of the Water Infrastructure Criteria, which aim to prevent 'greenwashing' in the green bond market by providing scientific standards for water-related investments. It covers built, nature-based, and hybrid infrastructure, with a specific focus on the newly added desalination criteria. The framework emphasizes a process-based approach to climate vulnerability assessments and sets a carbon intensity threshold of 100gCO2/kWh for desalination plants to align with the Paris Agreement.

The document describes revolving loan funds (RLFs) as self-replenishing financing mechanisms that provide low-interest loans to help property owners and municipalities fund environmental improvements. It highlights the Maryland Shore Erosion Control Revolving Loan Fund, which has provided approximately 700 loans over 52 years to support 'living shoreline' projects. It also discusses a feasibility study for a proposed RLF in Puget Sound, Washington, aimed at funding armor removal, soft shore protection, structure relocation, and structure elevation to combat sea level rise and coastal flooding.

The document analyzes the labor market crisis in Latin America exacerbated by COVID-19, highlighting the vulnerability of women, youth, and informal workers. It argues that the region's dependence on primary exports and low economic complexity increase its vulnerability to external shocks. To address this, the brief recommends transitioning toward 'green jobs' and a more complex productive matrix. Key proposals include investing in energy-efficient housing, nature-based solutions, female labor inclusion, digitalization to reduce informality, and aligning education with the requirements of a carbon-neutral economy.

The document examines urban flood challenges in five Sub-Saharan cities, highlighting the transition from traditional grey infrastructure to Integrated Flood Risk Management (IFRM) and Ecosystem-based Adaptation (EbA). It details specific interventions across Accra, Cape Town, Durban, Nairobi, and Mombasa, emphasizing that effective flood governance requires multi-stakeholder collaboration and the integration of social principles to protect vulnerable populations in informal settlements.

The report examines urban flooding in five cities across Ghana, South Africa, and Kenya, highlighting the vulnerability of informal settlements to climate-exacerbated rainfall and poor urban planning. It compares the maturity of South African cities in integrating EbA into policy against the more response-oriented, 'grey' infrastructure bias in Kenyan cities. Key findings emphasize that collaborative, whole-of-society governance and the integration of green and grey infrastructure are most effective for long-term resilience.

The policy brief positions carbon dioxide removal (CDR) as a public good and service, similar to wastewater treatment, because most approaches do not generate independent revenues and are avoided by commercial finance. It recommends that governments implement specific absolute volume targets for CDR within Nationally Determined Contributions (NDCs), provide dedicated subsidies, and eliminate regulatory barriers such as underground storage permitting. To ensure long-term scalability, the brief advocates for a universal carbon price, the integration of CDR into Article 6 of the Paris Agreement, and the development of robust monitoring, reporting, and verification (MRV) methodologies to maintain environmental integrity.

The 2021 snapshot of the Brazilian Forest Code implementation shows that while rural property registration (CAR) is well advanced nationwide, the subsequent analysis and validation stages remain significant bottlenecks. Only six states have fully operational Environmental Compliance Programs (PRA), and a group of states in the Northeast, Roraima, and Rio Grande do Sul continue to lag in legislation and implementation. Progress in 2021 included the incipient rollout of 'dynamic analysis' tools in five states and the regulation of the PRA in Amapá, Ceará, and Minas Gerais.

The annex evaluates the gap between the economic mitigation potential of forests and the quantitative targets set in NDCs for 32 high-potential countries. It identifies a global annual finance need for forest protection and restoration ranging from USD 45 billion to USD 460 billion, while noting that current 'green finance' flows are significantly lower than 'grey finance' flows directed toward sectors like agriculture.

The COP26 Resilience Hub served as a convening platform for the UNFCCC’s Race to Resilience, bringing together state and non-state actors to prioritise adaptation and resilience. The report identifies five core messages: the necessity of scaling Locally Led Adaptation (LLA), the urgent need for increased and diversified adaptation finance (preferring grants over loans), the requirement to bridge knowledge and implementation gaps, the role of Nature-based Solutions (NbS) across urban, coastal, and rural contexts, and the essential inclusion of marginalised groups—including women, youth, and Indigenous peoples—in decision-making. It also highlights the emergence of 'Loss and Damage' as a critical focus and notes a significant gap between current adaptation finance flows and actual needs.

The COP26 Resilience Hub Synthesis Report outlines five core messages for advancing global climate resilience: the necessity of Locally Led Adaptation (LLA), the urgent need for diversified and increased adaptation finance (preferring grants over loans), the bridging of knowledge and implementation gaps, the role of Nature-based Solutions (NbS) across urban, coastal, and rural settings, and the requirement to center marginalized groups—including women, youth, and Indigenous peoples—in decision-making. The report details thematic insights across ten areas, including finance, water, food, energy, and health, while emphasizing the need to scale these efforts toward COP27.

The report calculates that nature-based infrastructure (NBI) could cover between 9% and 14% of the global infrastructure gap, representing a potential annual investment of approximately USD 489 billion. Through a literature review and SAVi assessments, the document demonstrates that NBI often provides significant cost savings—averaging 50.6% less than grey infrastructure—and generates higher value, returning USD 10 for every dollar invested compared to USD 3.6 for traditional built infrastructure.

The NAP Global Network's 2020-2021 progress report highlights its efforts to accelerate climate adaptation in developing countries, particularly LDCs and SIDS. Key achievements include supporting 20 countries with their first Adaptation Communications (ADCOMs), expanding short-term technical assistance via the Country Support Hub, and advancing thematic work on gender-responsive planning and monitoring, evaluation, and learning (MEL). The Network's 2025 strategy focuses on transitioning from planning to implementation and enhancing inclusive, locally led adaptation.

The report identifies 23 financial transaction mechanisms and 35 enabling frameworks aimed at protecting and restoring nature. It categorizes these mechanisms into fiscal interventions, regulatory instruments, new government-enabled markets, traditional market-based instruments, and hybrid mechanisms. The authors argue that while innovation is high in identifying revenue streams, most mechanisms lack scale due to a reliance on public funding, a need for high private-value-capture potential, and a lack of performance certainty for large capital providers.

The 2021 state of global environmental governance was characterized by a shift toward voluntary pledges and a struggle to maintain multilateral progress during the COVID-19 pandemic. While some major meetings, such as the Glasgow COP, returned to in-person formats, many other processes remained in a 'maintenance mode' with only procedural outcomes. The report highlights a growing gap between environmental promises and action, exacerbated by systemic inequalities and vaccine disparity, which hinder the collective ability of states to address climate, nature, and pollution crises.

The NAP Global Network's 2020-2021 report highlights a shift toward short-term technical assistance via its Country Support Hub and a focus on transitioning from adaptation planning to implementation. Key achievements include supporting 20 countries with their first Adaptation Communications (ADCOMs), facilitating peer learning on gender-responsive action and conflict-sensitive planning, and developing knowledge products on climate and disaster risk finance and insurance (CDRFI). The Network's 2025 strategy emphasizes enhancing monitoring, evaluation, and learning (MEL) systems and elevating underrepresented voices, particularly women, in adaptation decision-making.

The NAP Global Network Strategy to 2025 establishes a framework to accelerate climate-resilient development in developing countries by enhancing National Adaptation Plan (NAP) processes. The strategy focuses on three main priorities: expanding tailored technical support, innovating peer learning, and making NAP knowledge more accessible and compelling. It aims to reach 30 new developing countries by 2025, ensure 30% of support goes to least developed countries (LDCs), and assist at least 15 countries in transitioning from planning to implementation. The Network operates through a Theory of Change that links activities like South-South peer exchange and the Country Support Hub to longer-term outcomes of higher-quality NAP processes and increased strategic investment in adaptation.
