The 2026 Market Intelligence Report by GreenCape outlines investment opportunities in the Western Cape's water and sanitation sector, focusing on private sector participation in infrastructure and water-efficient sanitation solutions (WESS). It highlights a transition toward innovative procurement and financing models driven by declining public grants and regulatory reforms.

This technical report provides a Sustainable Asset Valuation (SAVi) of the proposed rehabilitation of the Tirana–Durres railway in Albania. Using a systemic approach, the assessment compares a business-as-usual scenario with a railway scenario to quantify economic, social, and environmental impacts over a 30-year period (2023–2053). The analysis demonstrates that while the project is not economically viable under conventional cost-benefit analysis, it is highly profitable when integrating non-tangible societal benefits.

The 2023 Water Market Intelligence Report by GreenCape identifies significant investment opportunities in South Africa's public wastewater infrastructure, specifically focusing on metropolitan municipalities. The report highlights a critical state of existing infrastructure, the potential for circular economy solutions through sludge beneficiation, and the need for energy efficiency and renewable energy interventions to combat rising costs and energy insecurity.

This research paper by the Climate Policy Initiative evaluates methodologies for tracking investments in climate resilient infrastructure (CRI). The study pilots a framework based on five climate resilience principles across the water, transport, energy, and AFOLU sectors, finding that CRI investments are a small fraction of total infrastructure spending, with USD 87 spent on non-resilient projects for every USD 1 spent on CRI.

This policy brief explores how African pension funds can be leveraged to address the electricity access gap in Africa by investing in renewable energy-backed (RE) bonds. It argues that while there is a significant opportunity to align long-term pension obligations with long-lived energy infrastructure, systemic barriers regarding investment vehicles, regulatory frameworks, and government environmental policies must be addressed to unlock this capital.

This policy brief by the South African Institute of International Affairs examines the impact of the COVID-19 pandemic on green finance and development, contrasting the robust recovery packages in the global North with the funding gaps and systemic challenges in the global South. It highlights the risk that urgent health-sector spending may undermine environmental sustainability and advocates for institutional reforms, increased South-South cooperation, and coordinated global efforts to bridge the climate finance gap.

This report by the Climate Bonds Initiative analyzes the state of green bonds and sustainable infrastructure in New Zealand as of August 2019. It details the country's climate policy landscape, the growth of its green debt market, and identifies investment opportunities across five key sectors: renewable energy, low-carbon transport, sustainable water management, sustainable waste management, and green buildings.

This briefing by the Climate Bonds Initiative explores the critical role of climate adaptation and resilience in infrastructure investments to achieve the UN Sustainable Development Goals (SDGs). It highlights the current investment gap in the green bond market, where adaptation is significantly underfunded compared to mitigation, and proposes principles for improving definitions and disclosure to scale capital mobilization.

The National Water Resource Strategy (NWRS2), published in June 2013 by the Department of Water Affairs, provides a strategic framework for the protection, use, development, conservation, and management of South Africa's water resources over a five-to-ten-year period. The strategy aims to align water management with the National Development Plan (NDP) 2030 to eliminate poverty and reduce inequality. It identifies South Africa as a water-stressed country facing challenges such as security of supply, environmental degradation, and resource pollution. The NWRS2 prioritizes equitable water allocation, water conservation and demand management (WCWDM), and the establishment of robust institutional arrangements, including nine Catchment Management Agencies and nine Regional Water Utilities. To implement these goals, the document estimates a total sector investment requirement of R700 billion over ten years.

This strategic framework, developed by the African Ministers’ Council on Water (AMCOW) and the Global Water Partnership (GWP), provides a phased approach for African nations to integrate water security and climate resilience into their national development planning and investment decision-making processes.

This briefing outlines the financial requirements and strategies for achieving water security and climate resilience in Africa. It estimates the significant annual costs involved and proposes a blended financing approach that combines traditional water finance, official development assistance, and specialized climate funds to bridge the current investment gap.

This document is an annex to a report by the International Institute for Sustainable Development (IISD) that evaluates the potential for Nature-based Infrastructure (NBI) to reduce the global infrastructure investment gap. It provides a literature review of infrastructure needs across sectors such as water, energy, and transport, and compares the costs and value generation of NBI against traditional 'grey' infrastructure using SAVi assessments.

This case study by Mike Muller examines the political economy of water resource development and management within the Southern African Development Community (SADC). It argues that a disconnect exists between local/national priorities and regional agendas, largely because the latter have been driven by donor preferences for environmental conservation over infrastructure development. The author highlights that while some bilateral projects have succeeded, the broader region has suffered from 'economic water scarcity' due to a lack of long-term finance for infrastructure, a gap recently being filled by new financiers like China and Brazil.

The Aqueduct Floods Cost-Benefit Analyzer is a tool developed by the World Resources Institute to assess the economic feasibility of investing in flood protection infrastructure, specifically dikes and levees, to protect urban areas from riverine floods.
