Africa's freshwater ecosystems host at least 3,281 fish species, most of which are endemic, supporting millions of people through fisheries and providing critical ecosystem services. However, approximately 26% of these species are threatened with extinction due to damming, pollution, over-abstraction of water, invasive species, and climate change. The report highlights the critical role of the African Great Lakes and major river basins, the economic potential of the aquarium and recreational angling trades, and the urgent need for integrated management through initiatives like the Freshwater Challenge and the use of eDNA monitoring.

Mozambique is highly vulnerable to climate change, with projected increases in the frequency and intensity of cyclones, floods, and droughts. The report identifies agriculture, transport, and hydropower as the most critical economic sectors at risk. Agriculture faces significant threats to food security, particularly regarding maize yields, while transport infrastructure is hampered by a high proportion of unpaved roads. The energy sector is heavily dependent on hydropower from the Zambezi River Basin, which is projected to see declining runoff. Macroeconomically, Mozambique is exposed to risks from the global transition to a low-carbon economy due to its reliance on carbon-intensive exports like aluminium and coal. While the government has implemented policies such as Local Adaptation Plans and the National Climate Change Adaptation and Mitigation Strategy, it faces significant constraints in technical capacity and climate finance. The report recommends a transformative approach through Adaptation and Resilience Investment Platforms (ARIPs) to mobilize funding for infrastructure resilience and agricultural diversification.

The research paper examines the role of climate change literacy in Africa, highlighting a significant gap in public understanding of the human causes of climate change despite high perceptions of its impacts. It argues that increasing literacy—particularly for women and vulnerable populations—is essential for informed adaptation decisions, reducing vulnerability, and achieving the UN 2030 Sustainable Development Goals. The paper emphasizes the need for localized climate data, early warning systems, and the integration of climate literacy into education and policy to manage risks such as climate-forced migration and economic disruptions in sectors like hydropower.

The document details how Southern Africa is experiencing temperature increases above the global average, increased frequency of heatwaves and droughts, and significant economic losses. It projects severe future risks to food security, human health, and biodiversity, while emphasizing the need for transformative adaptation and increased climate finance to build resilience.

Southern Africa has experienced warming exceeding the global average, leading to increased heatwaves, droughts, and economic losses. Future projections indicate severe risks to food systems, human health, and biodiversity, with significant GDP losses if warming reaches 2°C. Adaptation requires transformative, equity-based approaches and a substantial increase in climate finance and research funding for African institutions.

The document details how climate variables from the Copernicus Climate Data Store (CDS) are integrated into the SAVi Energy model to quantify the impact of climate change on various power generation technologies. It provides a comprehensive literature review of how variables like temperature, wind speed, and precipitation affect the load factor and thermal efficiency of coal, gas, nuclear, biomass, hydro, solar, and wind power, as well as the efficiency of the electricity grid. The report includes a simulation for Johannesburg, South Africa, demonstrating that rising temperatures and changing precipitation patterns can significantly reduce the load factor and revenues for thermal and hydropower assets, while potentially increasing the load factor for wind energy.

The document details how climate indicators from the Copernicus Climate Data Store (CDS) are integrated into the SAVi tool to improve the analysis of infrastructure resilience. It covers a literature review of climate impacts on energy, irrigation, wastewater, buildings, roads, and nature-based infrastructure, providing specific equations to link climate variables to asset performance. The report includes simulation results for Johannesburg, South Africa, demonstrating how climate variables like temperature and precipitation affect load factors, thermal efficiency, and maintenance costs, ultimately impacting the economic viability and societal costs of these assets.

The SADC-HYCOS IV Project seeks to strengthen the capacity of 16 Southern African Development Community (SADC) member states to manage climate-related water risks. The project focuses on restoring hydrological monitoring stations damaged by Cyclones Idai and Kenneth, upgrading data transmission from expensive satellite systems to cost-effective GSM-modem technology, and establishing a centralised regional hydrological database. By improving the availability of contextually-appropriate hydrological information and early-warning systems, the project intends to provide adaptation benefits to approximately 140 million vulnerable people, particularly those reliant on agriculture and fisheries.

The document argues that current transboundary water governance in Southern Africa is inadequate due to a prioritisation of national sovereignty over regional integration. It highlights how climate change acts as a 'stress multiplier', exacerbating water scarcity and threatening energy and food security, as seen in the 2015/16 hydropower crises in Zambia and Zimbabwe. The author contends that while bilateral agreements (like the Zambezi River Act) provide some success in benefit-sharing, broader basin-level cooperation is hindered by weak mandates for river basin organisations (RBOs) and a lack of quantified economic co-benefits. The paper advocates for a 'positive-sum' approach to water management, integrating climate risks into investment planning to unlock international climate finance and prevent cross-border disputes.

The paper assesses the vulnerability of hydropower in the Zambezi River Basin to climate change, noting that a drying climate could reduce output by 10–20%. While long-term regional cost increases are small, hydro-dependent nations like Mozambique and Zambia may face near-term cost increases of 20–30%. The potential displacement of hydropower by coal could increase regional greenhouse gas emissions, impacting commitments under the Paris Agreement and necessitating stronger cooperative governance and integrated electricity planning.

The document highlights the significant risks climate change poses to hydropower potential in the Zambezi River Basin, emphasizing that financial viability for future plants depends on stable generation and revenue. It calls for a shift from analyzing individual plants to assessing entire national and regional energy systems using the most current climate data. The text notes that while cooperation in the basin is increasing, investment and operational decisions lack optimal coordination, a challenge expected to grow with the addition of four to five major new plants over the next 10-15 years. It recommends linking water modelling with regional energy system models to better understand economic trade-offs and the costs associated with climate change.

A research initiative applied a water supply and demand modelling tool to the Zambezi River Basin over 18 months to evaluate the impact of two climate scenarios ("wetting" and "drying") and two irrigation expansion scenarios. The analysis indicates that these factors could lead to significant negative impacts on both existing and planned hydropower investments in the region.

The report examines the intersection of domestic law, international investment law, freshwater law, and human rights law in the context of large-scale agricultural investments in Africa. It highlights how foreign investors often secure formal statutory water rights through contracts and treaties that prevail over the informal customary rights of local communities. The document emphasizes the increasing pressure on water resources due to population growth and climate change, particularly in Southern and Northern Africa. It analyzes the role of river basin organizations, such as those for the Senegal, Niger, and Lake Chad basins, in managing transboundary water resources. The report concludes that host states must integrate these parallel legal regimes to ensure sustainable water management and protect the human right to water.

The study estimates that Malawi, Mozambique, and Zambia face a potential US$596 million cost to maintain and repair road infrastructure due to climate-driven temperature and precipitation changes by 2050.
