This report uses the Sustainable Asset Valuation (SAVi) methodology to evaluate the economic, social, and environmental benefits of restoring 579 hectares of the Rocuant–Andalién coastal wetland system in Chile's Biobío region. The analysis demonstrates that nature-based infrastructure (NBI) is economically viable across all modelled scenarios, providing significant returns through avoided flood damage, carbon storage, and social value.

This briefing, produced by the ISEAL Alliance and the International Institute for Sustainable Development (IISD), examines the integration of voluntary sustainability standards (VSSs) into trade policy instruments to facilitate sustainable trade.

The International Institute for Sustainable Development provides the Tariff Analysis and Cost-Benefit Tool for Solarizing Irrigation (TACTS), an Excel-based resource for Indian policy-makers and developers. The tool addresses slow progress in the PM-KUSUM scheme by calculating viable tariffs, analyzing financial instruments, and quantifying the environmental and economic benefits of transitioning agricultural irrigation to solar power.

The International Institute for Sustainable Development has developed a replicable spatial targeting strategy for water retention projects in the Canadian Prairies, designed for use in ungauged basins. By utilizing models like PTMApp and public digital elevation data, the strategy aims to optimize the placement of natural infrastructure—such as wetlands and small dams—to maximize phosphorus reduction and mitigate the increased risks of floods and droughts caused by climate change.

This report by the NBI Global Resource Centre evaluates the economic, social, and environmental viability of implementing hybrid infrastructure—combining nature-based and grey infrastructure—to manage urban flood risks in Sekondi-Takoradi, Ghana. The analysis focuses on priority locations including Sekondi Market and Bakado, comparing a hybrid approach against a business-as-usual scenario.

This background note by the International Institute for Sustainable Development (IISD) compares two primary international frameworks for nature-based solutions (NbS): the IUCN Global Standard for NbS and the CBD Voluntary Guidelines for the Design and Effective Implementation of Ecosystem-based Approaches for Climate Change Adaptation and Disaster Risk Reduction.

This case study examines UNI2 Microcrédito, a Colombian microfinance institution, to evaluate the applicability of the Responsible Agricultural Investment (RAI) Tool to financial intermediaries rather than direct agribusinesses. The study analyzes how UNI2 supports business compliance with the Committee on World Food Security's Principles for Responsible Investment in Agriculture and Food Systems (CFS-RAI) among its rural and urban clients within agricultural value chains.

This executive summary from the International Institute for Sustainable Development (IISD) examines the role of 17 types of natural infrastructure in enhancing water resilience across the Canadian Prairies. It argues that natural assets—both conserved/restored and constructed—should complement conventional grey infrastructure to mitigate floods, secure water supplies during droughts, and improve water quality.

This report by the International Institute for Sustainable Development (IISD) provides detailed recommendations to strengthen the first draft of the outcome document for the Fourth Financing for Development Conference (FFD4). The document focuses on enhancing domestic resource mobilization, reforming private finance, improving climate financing for vulnerable nations, updating international trade rules, and establishing more robust debt-relief mechanisms.

This research paper by the International Institute for Sustainable Development (IISD) proposes a framework for applying intersectional approaches to climate change adaptation. Based on a May 2024 co-production workshop, the document outlines core and process principles designed to address overlapping structures of inequality that exacerbate climate vulnerability, integrating these into the iterative adaptation cycle.

This research paper by the International Institute for Sustainable Development (IISD) proposes a framework of fundamental and process principles to integrate intersectionality into climate change adaptation. Based on a May 2024 knowledge co-production workshop, the document aligns these principles with the iterative adaptation cycle—comprising impact assessment, planning, implementation, and monitoring, evaluation, and learning (MEL)—to better address the structural inequalities that exacerbate climate vulnerability.

This executive summary describes a spatial targeting strategy developed by the International Institute for Sustainable Development (IISD) to optimize the placement of water retention projects, such as wetlands and small naturalized dams, to reduce phosphorus loading in Canadian Prairie watersheds.

This briefing provides an overview of the European Union Deforestation Regulation (EUDR), detailing compliance requirements for operators and small and medium-sized enterprises (SMEs), and the role of voluntary sustainability standards (VSSs) in meeting these obligations.

This briefing from the International Institute for Sustainable Development (IISD) advocates for the use of model investment contracts in the agricultural sector to promote responsible investment and sustainable development, particularly in developing countries where domestic laws may be insufficient.

The International Institute for Sustainable Development (IISD) provides recommendations to the British government regarding the North Sea's energy transition, advocating for a managed decline of oil and gas production aligned with 1.5°C goals.

This policy brief by the International Institute for Sustainable Development argues for reforming the European Union's Public Procurement Directive to transition from voluntary to mandatory green public procurement (GPP) to better align public spending with climate goals.

The 'Cities in Transition' executive summary by the International Institute for Sustainable Development (IISD) argues that energy and climate policy must integrate urban planning to reduce total energy demand. Using the city of Winnipeg as a primary case study, the research demonstrates that shifting from car-oriented sprawl to compact, walkable communities reduces emissions and lowers municipal infrastructure costs.

The International Institute for Sustainable Development (IISD) argues that a recent draft of the Outcome Document for the Fourth Conference on Financing for Development (FfD4) weakens commitments to the oversight and reporting of tax expenditures. The statement calls for the reinstatement of stronger language to ensure countries can rationalize ineffective tax expenditures and increase domestic resource mobilization to fund sustainable development, climate, and biodiversity goals.

The 'Climate Risk Profile: Belize' report outlines the climatic hazards facing Belize, specifically focusing on the Maya Forest Corridor, Glover's Reef Marine Reserve, and South Water Caye Marine Reserve. It emphasizes the need for nature-based solutions (NbS) that are gender-responsive and socially inclusive to mitigate threats to biodiversity, food security, and socio-economic development.

This case study describes the Natur'ELLES project in Senegal, which uses research, data, and educational initiatives to promote sustainable fishing in mangrove forests and increase the participation of women in natural resource management.
