Such land restitution programmes are partially motivated by a hope that restitution will enable Indigenous communities to influence land use in ways that will also generate public environmental benefits. However, little is known about how Indigenous communities change land use after land is returned to their stewardship. Here we show the land-use impacts of a Chilean restitution programme that, between 1994 and 2022, returned 217,716 ha of land to Mapuche communities. Using a difference-in-differences research design, we find that land restitution led to more grasslands, a common Mapuche use of land, and fewer non-native forest plantations, a use of land that the Mapuche have frequently protested against. However, restitution did not change the extent of natural forests. Given this reconfiguration of land use, restitution has led to insignificant changes in carbon sequestration or biodiversity. Our results complicate common narratives that Indigenous land reform will always yield improvements in environmental outcomes. Careful consideration of the local cultural context and the legacies of dispossession can help to set appropriate expectations for the environmental co-benefits of these reforms. Indigenous land restitution is often expected to deliver environmental co-benefits alongside redressing historical dispossession, but evidence of land-use change after restitution is limited. This study evaluates the land-use and environmental impacts of returning over 200,000 ha to Mapuche communities in Chile.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 10","pages":"1582-1594"},"PeriodicalIF":32.1,"publicationDate":"2026-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the largest hydrogen consumer, China aims to scale up renewable-based hydrogen production to 40–75 Mt yr−1 by 2050. Here we uncover the spatiotemporal profiles of water constraints for the electrolytic hydrogen demand across 2,853 county-level cities of China. We then propose city-specific solutions to address these water constraints and model associated carbon and cost implications. We find that water resources constrain ~30% of projected electrolytic hydrogen demand in 2030 and 2050, which is exacerbated to over 50% by stricter water usage limits. Such water constraints risk carbon mitigation opportunities of ~174–299 MtCO2e in 2050. We identify a city-specific cost-minimum strategy, primarily based on using reclaimed water for electrolytic hydrogen production. This strategy can unlock 99% of water-constrained mitigation opportunities, with costs only ~20% higher than using natural water in 2050. Scaling up electrolytic hydrogen is central to deep decarbonization, but its substantial water needs clash with growing water scarcity. A study mapping 2,853 Chinese county-level cities shows that using reclaimed water can unlock 99% of water-constrained carbon mitigation at only ~20% higher cost.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 10","pages":"1669-1679"},"PeriodicalIF":32.1,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, emergency resources are often inefficiently allocated, as conventional strategies usually overlook mobility dynamics and thereby exacerbate vulnerability. Here, by capturing flood-induced human dynamics using agent-based modelling, we investigate the emergency resource allocation issue (official emergency shelters and dual-use public service facilities) across China’s 21 large cities. We find that 43% of these cities face notable resource demand‒supply mismatches (>2,000 km2 per city) during 100-year floods, exposing 16.76 million residents to preventable risks. Our SSP5-8.5 projections indicate that substantial mismatch will persist by 2050 despite the declining population in China, while flooded areas are expected to expand fivefold owing to climate change. As a solution, strategically retrofitting 30% of high-deficit zones yields benefit-to-cost ratios exceeding 28 via reduced mortality, societal co-benefits, carbon savings and economic continuity (US$0.20–3.05 billion savings per city with a per capita investment of merely US$1.39). These findings underscore the critical links between flood-induced human behaviour and emergency resource optimization in climate-adaptive urban development. Flood emergency resources are often misallocated as planning relies on static population data rather than dynamic human mobility during disasters. A study now models flood-induced mobility across 21 Chinese cities, revealing widespread resource mismatches and cost-effective retrofitting strategies.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 10","pages":"1569-1581"},"PeriodicalIF":32.1,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extreme weather affects both demand and supply, leading to power system stress; in Europe this stress spreads continentally beyond the meteorological root cause. Here we use an approach based on shadow prices to identify periods of elevated stress called system-defining events and analyse their impact on the power system. By classifying different types of system-defining events, we identify challenges to power system operation and planning. Crucially, we find the need for sufficient resilience back-up (power) capacities whose financial viability is precarious owing to weather variability and weather-induced risk. Furthermore, we disentangle short- and long-term resilience challenges (from multi-day to annual scale) with distinct metrics and stress tests to incorporate both into future energy modelling assessments. Our methodology and implementation in an open energy system model (PyPSA-Eur) can be re-applied to other systems and help researchers and policymakers in building more resilient and adequate energy systems. Net-zero power systems are vulnerable to extreme weather, but how much back-up capacity is needed to keep systems reliable under variable weather remains unclear. A study using 80 years of European data identifies key stress events and proposes metrics for short- and long-term resilience.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 10","pages":"1534-1545"},"PeriodicalIF":32.1,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most studies have focused on large rivers or aggregated regional assessments, leaving limited understanding of how flood risk varies across river sizes. By integrating high-resolution hydrodynamic simulations, demographic projections and current flood defence levels across the contiguous USA, our projections suggest that smaller rivers tend to exhibit greater sensitivity to climate change-induced increases in flood intensity by 2050. Meanwhile, flood defences along small rivers are currently the weakest, potentially placing nearby populations at disproportionately higher risk. Restoring future flood risk along small rivers to historical levels would require the highest flood defence investments among all river sizes—up to ~US$4 million (2005) per kilometre. The elevated flood risk for residents along small rivers appears to be primarily driven by increasing climate-related hazard severity and low defence levels, whereas flood risk along larger rivers is dominated by rising exposure. Together, these results indicate a potential mismatch between future flood defence needs and existing defence levels across river sizes, highlighting the urgent need to prioritize investments for communities along small rivers. Climate change is expected to intensify river flooding, yet small rivers are often overlooked in large-scale risk assessments. A study now projects that residents along small rivers in the USA face the highest future flood risk and the largest defence-investment needs by 2050.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 10","pages":"1558-1568"},"PeriodicalIF":32.1,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fund infrastructure, utilities often raise rates, increasing water bills for low-income households. The resulting affordability impacts depend on utility costs and interactions between rate design, financing, climate and household demands. Here we develop a city-scale modelling framework to estimate climate change impacts on water affordability, integrating climate, utility adaptation decisions and demand. In Santa Cruz, California, we find that climate change alone could double water bills by mid-century, leaving an additional 7–16% of Santa Cruz households with unaffordable water. Our results suggest that climate change may lead to greater water affordability challenges than previously estimated in hotspots where supply is vulnerable to climate change. This highlights the need for policy intervention and financing to ensure climate adaptation does not compromise affordability. The magnitude of climate-related affordability challenges depends on local context, requiring city-scale assessments. Water affordability is a growing challenge, but how climate change may worsen it through costly infrastructure adaptation remains unclear.
