In this Review, we summarize the pathways causing transboundary environmental and human health impacts of pesticide use in food production, and explore strategies to reduce reliance on pesticides. Once applied to crops, pesticides are transported through surface and groundwater flows, atmospheric dispersion and wildlife migration. Globally, 7.2% of pesticide input leaches below the root zone potentially reaching groundwater, with atmospheric droplets (10–50 µm in size) transported between 250 m and several kilometres from the point of application. International food trade drives pesticide use and, of all food products, fruit and vegetables have the highest embodiment of pesticide impacts, including risk to consumers through dietary intake of residues. Pesticide residues are found on 62% of rice from Pakistan and on 85% of harvested fruits, berries, pulses and leafy vegetables in Western countries. Moreover, residues on ~2–4% of domestic foods in China, New Zealand, the European Union and the USA exceed legal safety limits. Through stringent regulations on pesticide use and enforced compliance with pesticide residue limits, international trade can encourage adoption of low-pesticide cropping strategies and decision support systems that prioritize biodiversity and human health while maintaining yield. Future research should focus on quantifying transboundary pesticide impacts, constraining the environmental fate and transport of pesticides, and increasing environmental monitoring, especially in the Global South. Pesticide use in agriculture helps protect crop yields and support global food security, but environmental contamination and residues on food products pose risks to ecosystems and human health. This Review explores transboundary pesticide impacts of internationally traded foods, finding that fruit and vegetables have the highest embodied impacts.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 6","pages":"383-400"},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Review, we discuss the interactions between sand transport and vegetation processes (ecomorphodynamics) that give rise to the foredune-building feedback as illuminated by empirical and modelling studies. Foredune shape and alongshore continuity depend primarily on sand supply, vegetation density and growth form. For instance, low-lying, creeping herbaceous species tend to form short embryo dunes, whereas tall, dense grasses that grow vertically tend to form tall, narrow foredunes. Climate and weather events, herbivory and anthropogenic disturbances of varying scale affect the foredune-building feedback. For example, small local scale disturbances, such as herbivory or trampling, cause local vegetation loss and erosion. Management activities, such as beach nourishment, can increase foredune sand supply, leading to foredune rebuilding, although the presence of infrastructure on the back beach can inhibit foredune development. At a regional scale, hurricanes and tropical storms cause substantial dune erosion and overwash, potentially resetting the foredune-building process. Sea-level rise exacerbates the effects of storms, leading to increased erosion, saltwater intrusion and a potential landward shift in foredune location. Future research should prioritize integrated ecomorphodynamic observations and modelling to fill critical knowledge gaps and address the effects of changing climate on the foredune-building process. Coastal dunes are highly dynamic systems. This Review considers the foredune-building feedback between sand transport and vegetation and how their influence on foredune morphology, size and stability is affected by climate change and anthropogenic disturbances.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 6","pages":"417-432"},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Review, we explore the conditions that enable the development of natural hydrogen resources in the geological subsurface, by examining the processes of hydrogen generation, migration, accumulation and preservation. Natural hydrogen is generated within the continental crust by two key mechanisms, water–rock reactions where Fe2+, dominantly in ultramafic rocks, is oxidized to Fe3+, and by radiolysis of water via radioactive elements U, Th and K found in upper-crustal rocks. These two generation reactions operate on very different timescales, ranging from thousands to millions of years for water–rock reactions in highly fractured rocks, to tens to hundreds of millions of years for water-limited water–rock and radiolysis reactions. Different globally widespread terrane types have the potential for hydrogen accumulations: continental margin ophiolite complexes, alkaline granite terranes, large igneous provinces, and Archaean greenstone belts and tonalite–trondhjemite–granodiorite granitic batholiths. Exploitation of natural hydrogen would have a low-carbon footprint, but continental systems do not provide a regenerating system on decadal to centennial timescales, and should not be considered a renewable resource. Calculating hydrogen generation by water–rock reactions is subject to more uncertainty than radiolysis reactions, but improving these estimates should be a priority for future research. Natural hydrogen is generated through chemical and radioactive processes in the Earth’s crust, and could be an important future clean chemical feedstock and energy resource. This Review examines the processes of geological hydrogen generation, migration, accumulation and preservation that enable the development of exploitable reserves.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 5","pages":"342-356"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the timings of initial collision and suturing in the Himalaya and Zagros remain debated. In this Review, we summarize the timings, similarities and differences between the India–Eurasia collision and the Arabia–Eurasia collision, by comparing their sedimentary, magmatic, metamorphic, structural and palaeomagnetic records. The India–Eurasia collision is tightly constrained to have initiated in the central Himalaya at 65–59 Ma, possibly progressing towards the western and eastern Himalayas by 55–50 Ma. By contrast, the initial collision in the Zagros is loosely constrained to ~34 Ma, with a possibility of diachronous collision, younging to the southeast. Similarities between the two collisions include pre-collisional accretionary tectonism and magmatism, syn-collisional deformation and sedimentation, and crustal thickening. Apparent differences in lithospheric dynamics, deformation styles and metamorphism are attributed to variations in convergence rates, durations and magnitudes. Future research should focus on data-driven modelling and geophysical imaging beneath the Tibetan and Iranian plateaus to further quantify the geodynamic processes and driving forces contributing to continuous plate convergence, plateau formation and their surface impacts. The collision of the Indian, Arabian and Eurasian plates formed the Tibetan and Iranian plateaus, but its timing and processes remain debated. This Review explores the evidence behind initial collision estimates and discusses the tectonic and geodynamic implications.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"6 5","pages":"357-376"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
