However, cropland abandonment is also steadily occurring, with workforce shortages recognized as one of major contributing factors. Here we demonstrate that the agricultural workforce will be a dominant constraint on cropland availability and its future changes, complementing the currently considered environmental constraints. On the basis of the historical trajectory, this study projects additional offsets in future cropland availability resulting from the introduction of workforce constraints. Although global cropland demand can be met without further expansion into natural areas, regional disparities persist between the workforce-constrained cropland availability and cropland use projected under widely established shared socioeconomic pathway and representative concentration pathway (SSP–RCP) scenarios and their assumptions. These gaps suggest the need for targeted policies supporting additional workforce development, technological innovations in the agricultural sector and migration inflows to sustain projected levels of cropland usage. Future food demand is expected to drive cropland expansion, but emerging agricultural workforce shortages, contributing to local cropland abandonment, might limit food production. This study models the future impacts of labour constraints on cropland use under socioeconomic and climate scenarios.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1277-1288"},"PeriodicalIF":32.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41893-026-01824-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional oxidation processes are prone to C–C bond cleavage, resulting in the inefficient utilization of the glycerol three-carbon backbone. Here we report a spatially decoupled photoelectrocatalytic–biocatalytic relay system that is able to efficiently upgrade glycerol to sorbose, an important six-carbon sugar used in the food, pharmaceutical and cosmetic industries. This system uses a WO3–Bi photoanode to selectively oxidize glycerol into two distinct three-carbon products: glyceraldehyde and dihydroxyacetone. Subsequently, these two three-carbon products are coupled via an aldol addition reaction, driven by a mutant fructose-6-phosphate aldolase catalyst. Continuous tandem operation enables the highly selective conversion of glycerol into a single six-carbon product, sorbose. Furthermore, coupling the WO3–Bi photoanode with an Si photocathode followed by enzyme catalysis relay achieves a sorbose yield of 31.66 mmol genzyme−1 h−1 under solar light irradiation without the need of external energy input. This work presents a sustainable platform for upgrading biomass-derived glycerol into valuable six-carbon chemicals under mild conditions, providing a green and efficient route for biomass valorization. As a low-cost by-product of biodiesel production, glycerol is an attractive feedstock for the sustainable manufacturing of high-value chemicals. This study demonstrates a method to convert glycerol into sorbose, a valuable sugar used in the food and pharmaceutical industries.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1220-1231"},"PeriodicalIF":32.1,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785268","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, whether PAs have preserved historical wildlife assemblages remains poorly quantified, mainly due to a lack of comparable data from historical and current periods. Here we used comprehensive data from historical investigations during the 1950s and 1970s, as well as current surveys based on 8,300 camera traps between 2008 and 2021 across 85 PAs in China, to assess range contractions of 82 large- and medium-bodied mammals. We found that carnivores disappeared from 59.4% of their historical sites, a rate much higher than that observed in ungulates (37.2%). Moreover, while 52.9% of PAs retained more than 70% of their ungulate species, over 70% of PAs lost over half of their carnivore species, with PAs in southern China being range contraction hotspots, particularly for carnivore species with larger body sizes and shorter generation lengths. Our findings reveal widespread range contraction of carnivores in China’s PAs compared with historical periods, driven primarily by legacy effects of large-scale anthropogenic disturbances and human–wildlife conflict, necessitating initiatives to maintain and restore historical assemblages of carnivores alongside habitat protection. Protected areas can be important in conserving key mammal species that help maintain ecosystem functioning. The authors examine how well protected areas achieve this, in the context of historical habitat loss and human–wildlife conflict, for 82 mammal species across China.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1188-1197"},"PeriodicalIF":32.1,"publicationDate":"2026-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785274","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, most existing sensors are subjected to polymer-based substrates, which intrinsically experience poor thermal resistance, insufficient structural and chemical robustness, and unsustainable large-scale fabrication. Here we develop a winding chemical vapour deposition method using waste plastic garbage bags as solid carbon precursors to achieve uniform graphene growth on silica fabric (G@SF), simultaneously enabling high-performance textile production for cost-efficient sensor fabrication and waste plastic upcycling to address environmental pollution. By leveraging the advantages of both the woven architecture and the laser-responsive nature of the graphene layer, multifunctional sensors can be fabricated from the obtained G@SF via programmable laser erasing. These sensors have reliable multimodal sensing capabilities, including temperature detection, pressure and deformation monitoring and near-field communication. The G@SF sensors exhibit excellent thermal stability of up to 1,000 °C, mechanical flexibility and chemical robustness. A proof-of-concept smart glove that integrates G@SF sensors further highlights their multifunctionality and resilience under harsh conditions. This study presents a viable strategy for fabricating sustainable and high-performance flexible sensor fabrics from plastic waste. Most flexible sensors are fabricated using polymer-based substrates, which are intrinsically unsustainable and insufficiently robust. This study shows a strategy for using waste plastic to fabricate graphene-based flexible sensors that can address the drawbacks of polymer-based sensors.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1207-1219"},"PeriodicalIF":32.1,"publicationDate":"2026-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785282","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}

We compiled a national database of 363,282 heritage relic sites in China, including 307,666 heritage trees, 8,155 traditional villages, 5,060 cultural heritage sites and 42,401 religious sites, and integrated it with historical forest coverage data (1900–2020) and a high-resolution human footprint index (2020). Here, using geostatistical analysis and machine learning, we show that heritage relics function as long-term refugia, preserving forests during periods of deforestation and enhancing recovery during large-scale restoration. Heritage trees and traditional villages are associated with higher forest coverage and faster regeneration than religious or cultural heritage sites, especially in southern China and in regions of lower anthropogenic pressure. Yet these protective effects diminish as human footprints intensify, revealing the conditional resilience of relic-associated forests. Our findings demonstrate that biocultural heritage is not merely a repository of cultural values but also a dynamic ecological infrastructure that sustains biodiversity and ecosystem services over centuries. Integrating relic protection into conservation strategies offers an underused pathway for achieving global biodiversity and sustainability targets, including the Kunming–Montreal global biodiversity framework and the sustainable development goals. Deforestation over the past century represents a crucial challenge for biodiversity conservation, but whether biocultural sites can improve conservation outcomes is still unclear. This study examines biocultural sites across China to test how these influence forest conservation outcomes.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1160-1170"},"PeriodicalIF":32.1,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785269","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}

Systemic cooling poverty (SCP) describes conditions in which individuals are prevented from attaining thermal safety as a result of intersecting forms of systemic deprivation. Here we quantify SCP across 28 countries, mostly in the global south, by combining household survey data (n = 1,155,106 households), climate records and infrastructure datasets. We operationalize SCP through five dimensions—climate exposure, infrastructure and assets, social and thermal inequalities, health, and education and working standards—and construct an SCP index at subnational scale. SCP is widespread and unevenly distributed: almost 600 million people experience high levels of deprivation across SCP dimensions. Education, working standards and climate exposure are the most prevalent drivers. These results show that vulnerability to extreme heat arises from intersecting climatic and socio-institutional factors, highlighting the need for coordinated policies that address multiple dimensions of heat adaptation. The multiple factors preventing people from staying safe during heatwaves and hot spells are poorly quantified. A study now measures systemic cooling poverty in the global south, revealing that almost 600 million people are at risk of heat-related harm and that deprivation patterns vary markedly both across and within countries.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"9 8","pages":"1266-1276"},"PeriodicalIF":32.1,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785265","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}
