The report forecasts that Mauritius will maintain steady economic growth and a high income per capita relative to its African peers, while facing challenges from an ageing population and a high dependence on energy imports. It projects a decline in extreme poverty and a gradual increase in carbon emissions as the economy expands, despite the country's high readiness to respond to climate change.

As of March 30, 2026, the western U.S. is experiencing a historic snow drought, with snow water equivalent at its lowest record for April 1 and 65% below the 1991-2020 normal. This condition is attributed to a record-warm winter and a record-shattering March heat wave fueled by heat-trapping pollution. Long-term trends from 1955 to 2023 show an 18% average decline in April 1 snowpack across 652 monitoring stations, with snow droughts growing 28% longer between 1980 and 2018. These trends increase risks for water supplies, hydropower, and wildfires, with projections suggesting a further 25% decline in snow water equivalent by 2050.

February 2026 was the fifth-warmest month globally on record, with the contiguous U.S. experiencing its second-warmest winter in 132 years. A critical 'snow drought' affected the western U.S., where snow-covered areas in January were only 34% of normal, threatening water supplies for agriculture and energy. Climate Central's analysis indicates that human-driven climate change significantly influenced winter temperatures, particularly in the Southwest, and is the primary cause of spring warming in 98% of 241 examined U.S. cities.

The report argues that the Amazon forest is a strategic economic asset for Brazil because it regulates the 'flying rivers' that distribute rainfall across the country. Deforestation of approximately 20% of the biome has already led to significant financial losses in the hydroelectric sector and increases vulnerability in agriculture, urban water systems, and logistics. The authors conclude that protecting the forest is a national strategic imperative to ensure economic stability and development.

The study uses an integrated approach combining hydroclimatic hazard impact and supply-driven input-output models to estimate damages to Sweden's food, electricity, and water supply. Between 2005 and 2022, combined hydroclimatic hazards caused EUR 8.4 billion in economic losses across the agriculture, electricity, and insurance sectors, with floods contributing the highest share of damage.

Climate Central's analysis of 241 U.S. cities shows that 97% experienced an increase in average spring temperatures between 1970 and 2024, with an average rise of 2.4°F. The Southwest saw the most significant warming, and 80% of analyzed locations now experience at least one additional week of warmer-than-normal spring days. These trends are linked to global warming and contribute to increased wildfire risk, prolonged allergy seasons, and stressed water supplies in the western U.S.

A case study in Bharatpur, Nepal, identifies dengue fever and skin infections as prevalent infectious diseases, linked to poor waste management and inadequate sanitation. While nature-based solutions like green streets and rainwater harvesting can mitigate hazards by filtering water and reducing temperatures, the study concludes that NBS cannot replace essential urban infrastructure and services to improve public health outcomes.

The document evaluates global efforts to achieve universal water and sanitation coverage, contrasting the historical use of private sector investment with a renewed shift toward public governance models based on improved institutional regulation and competition management.

The Harare City Profiling Report 2025 details the challenges facing Zimbabwe's capital, characterized by rapid informal urban growth, severe infrastructure decay, and a strained relationship between the opposition-led city council and the national government. While Harare serves as the country's economic hub, it suffers from critical gaps in water, sanitation, and waste management, with a significant portion of the population living in informal settlements. The report highlights a severe fiscal crisis where the city relies almost entirely on its own limited revenue sources while facing low payment compliance and high levels of non-revenue water.

The report provides a comprehensive profile of Luanda, highlighting its rapid population growth, extreme economic inequality, and a highly centralised governance structure. While the city has benefited from oil wealth, significant service delivery gaps persist, particularly in housing, water, and sanitation for those in informal settlements. The report notes that Luanda is one of the most congested cities globally and faces increasing climate risks, including flooding and sea-level rise.

The Maputo metropolitan area, with a population of 2.9 million, serves as Mozambique's primary economic and political hub but faces significant challenges in service delivery and infrastructure. While the city shows economic growth and improving health indices, it is characterized by high levels of informal settlements, inadequate sanitation, and a fragmented local government system with limited functional autonomy. Key infrastructure projects like the Maputo-Katembe bridge have improved connectivity, but the region remains one of the poorest primary cities in the SADC region, with a heavy reliance on charcoal for cooking and a high prevalence of waterborne diseases among children.

The report details the compilation of pilot ecosystem accounts for Kaduna and Nasarawa states in Nigeria between 2015 and 2020. Using the SEEA-EA framework and ARIES AI technology, the study estimated biophysical supply for climate regulation (carbon storage), soil retention, crop production, pollination, and water supply. Findings indicate that while total carbon stocks and soil retention remained relatively stable, there were significant shifts in land cover, including an increase in deciduous broadleaf forests and a loss of shrublands. The report emphasizes the lack of local geo-referenced data and the need for an institutional framework to support independent national environmental accounting.

Using the Climate Shift Index (CSI), Climate Central found that human-caused climate change significantly boosted spring warmth in 2024, affecting 300 million people in the U.S. and approximately one in four people globally. The strongest influence was observed in coastal and island regions, such as Puerto Rico and Florida, while areas with the highest temperature anomalies, like the Upper Midwest, showed lower CSI levels due to higher historical temperature variance.

The guide provides a structured approach based on the XLRM framework to assess investments in water supply systems. It emphasizes comparing 'environmental additional investments' (IAA) against traditional infrastructure and efficiency measures. Using two Colombian case studies (Río Chinchiná and Río Chicamocha), the document demonstrates how nature-based solutions like ecosystem restoration can improve water regulation and increase low-flow (Q95) availability, thereby reducing the gap between water supply and demand. It also analyzes the Colombian regulatory framework, specifically Resolution CRA 907 of 2019, which allows certain environmental costs to be recovered through tariffs.

Climate Central analyzed precipitation data from 1969-70 to 2022-23 for the contiguous U.S., finding that while some regions have balanced seasonal rainfall, others rely heavily on a single season. Specifically, the West and Northwest are dominated by winter precipitation, while the Plains and Upper Midwest rely on summer rainfall. Climate change is altering these patterns, with a general increase in precipitation east of the Rockies and a decrease to the west. Warmer temperatures are increasing atmospheric moisture—approximately 10% more since 1970—which enhances extremes such as heavy downpours and intensifying droughts.

The document reports that 97% of 246 analyzed U.S. locations experienced an increase in average temperature during the period from December 25 to January 5 between 1969 and 2021. It details regional shifts in snowpack and precipitation, noting that winter is the fastest-warming season for most of the U.S., which increases the likelihood of precipitation falling as rain rather than snow.

Japan utilizes the 2018 Climate Change Adaptation Act and a revised 2021 plan to coordinate adaptation across ministries using 66 Key Performance Indicators. Domestically, the country employs local adaptation centers in 38 of 47 prefectures and the A-PLAT information platform to support municipal planning. Internationally, Japan provides technical expertise in disaster risk reduction, manages the Asia-Pacific Climate Change Adaptation Information Platform (AP-PLAT), and has committed to doubling adaptation finance to approximately $14.8 billion between 2021 and 2025.

Analysis of 246 U.S. locations from 1970 to 2021 shows that 98% experienced an increase in average winter temperatures, with the Great Lakes and Northeast regions seeing the most significant warming. Winter is the fastest-warming season for 38 out of 49 states. While extreme cold events still occur, warming winters threaten regional economies through reduced snowpacks in the West, lower fruit yields, and the migration of disease-carrying pests.

The report demonstrates that deforestation in the Amazon, specifically within the Xingu River Basin, significantly reduces rainfall in Mato Grosso. A counterfactual scenario where all Xingu Indigenous Territories are deforested predicts an average annual precipitation decrease of 7%, with more severe reductions during the dry season. These changes threaten agricultural productivity, urban water supplies, and hydroelectric power generation, with the center and north of the state being most vulnerable.

This report by CPI/PUC-Rio uses an atmospheric transport model to demonstrate that deforestation in the Amazon rainforest reduces rainfall in Mato Grosso. A counterfactual analysis of the total deforestation of indigenous territories in the Xingu River Basin suggests a 7% reduction in average annual precipitation, with more severe impacts during the dry season. The study highlights the critical role of protected forest areas in sustaining agricultural productivity, hydroelectric power generation, and urban water supplies.
