In this Review, we outline the global trends in harmful algal bloom occurrence and explore the drivers, future trajectories and potential mitigation strategies. Globally, harmful algal bloom occurrence has risen since the 1980s, including a 44% increase from the 2000s to 2010s, especially in Asia and Africa. Enhanced nutrient pollution owing to urbanization, wastewater discharge and agricultural expansion are key drivers of these increases. In contrast, changes have been less substantial in high-income regions such as North America, Europe and Oceania, where policies to mitigate nutrient pollution have stabilized bloom occurrences since the 1970s. However, since the 1990s, climate warming and legacy nutrient pollution have driven a resurgence in toxic algal blooms in some US and European lakes, highlighting the inherent challenges in mitigating harmful blooms in a warming climate. Indeed, advancing research on harmful algal bloom dynamics and projections largely depends on effectively using data from multiple sources to understand environmental interactions and enhance modelling techniques. Integrated monitoring networks across various spatiotemporal scales and data-sharing frameworks are essential for improving harmful algal bloom forecasting and mitigation. Harmful algal blooms degrade inland aquatic ecosystems and pose a risk to water security. This Review explores the underlying drivers of hotspots and global trends in harmful algal blooms, and identifies potential solutions for bloom monitoring and mitigation.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"5 9","pages":"631-644"},"PeriodicalIF":0.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165813","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}

Since 1915, 257 TSF failures have occurred, releasing a total of ~250 million m3 of tailings, destroying areas up to ~5,000 km2, killing an estimated 2,650 people and impacting ~317,000 people through displacement, property damage, and risks to livelihoods and health. In this Review, we provide an interdisciplinary approach to understanding the causes, effects and response to TSF failures, applying a disaster risk reduction framework. TSF failures can occur owing to earthquakes, overtopping, weak foundations and liquefaction, among other mechanisms. The severities and volumes of TSF failures have increased since the year 2000, owing to increasing mine waste generation from the exploitation of larger, lower-grade deposits. Despite the increasingly severe impacts, the mining industry has been hesitant to use the term ‘disaster’ to analyse TSF failure, presumably to avoid liability. TSF failures should be considered as disasters when they cause severe disruption to the functioning of ecological and social systems. Future research should build on attempts to link tailings facility locations to situated risk factors by improving spatial and time series analysis, reducing reliance on corporate disclosures, and increasing the visibility of priority locations and patterns of concern. Mine tailings are voluminous and often toxic wastes, whose management is a global safety and sustainability challenge. This Review summarizes the major tailings storage facility disasters and impacts, emphasizing the urgent need for risk reduction approaches for management and policy.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"5 9","pages":"612-630"},"PeriodicalIF":0.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935422","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}

Observations suggest a shift towards stronger and earlier positive IOD (pIOD) events alongside an increased amplitude of sea surface temperature (SST) anomalies, but uncertainty remains, impeding assessments of ongoing changes. In this Review, we synthesize the available knowledge of projected changes in the IOD during the twenty-first century under anthropogenic warming. Compared to observations, models struggle to simulate the Bjerknes feedback, asymmetry in the strength of positive and negative IOD anomalies and El Niño–Southern Oscillation or monsoonal forcings. Yet several models do capture important feedbacks reasonably well and offer useful tools with which to assess IOD evolution. A pIOD-like SST warming pattern (an enhanced west-minus-east SST gradient) alongside shifts in feedback process drive corresponding changes to the IOD. Over the course of the twenty-first century, robust changes include: enhanced IOD SST variability (as measured by the first principal component of spring SST variability, not the dipole mode index); an increase in strong rainfall pIOD events; an increase and decrease in the frequency of strong-pIOD and moderate-pIOD, respectively, as defined by SST; and an increase in the frequency of early-pIOD events. Palaeo evidence reveals similar increases in the magnitude and frequency of pIOD events underpinned by a similar pattern of mean state change (Last Glacial Maximum, post-1960), reinforcing IOD projections. Sustained international efforts are needed to improve IOD simulations and reduce projection uncertainties. The Indian Ocean Dipole (IOD) exerts strong control on the Indo-Pacific climate. This Review outlines twenty-first-century changes in the IOD, noting robust increases in eastern pole sea surface temperature variability, more frequent strong and early positive IOD events, and less frequent moderate positive IOD events.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"5 8","pages":"588-604"},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864024","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, concerns regarding their potential health and environmental impacts have been raised. In this Review, we assess the opportunities of ENMs in environmental applications versus their potential public and environmental health risks, focusing on water treatment and reuse, and identify strategies for their responsible use. Life-cycle analyses indicate that the highest potential environmental and health impacts of ENMs used in commercial products are associated with production rather than incidental release during use. Typically, the detected or predicted ENM concentrations are 1 to 4 orders of magnitude lower than their respective predicted no-effect concentrations. In addition, ENMs often undergo passivating transformations, such as agglomeration and oxidation, reducing risks after release. Therefore, the environmental and health risks of ENMs are relatively low. However, some point sources under extreme scenarios, such as sewage effluent, can potentially increase localized risks. Adopting green chemistry and immobilization strategies can further limit the release of ENMs, minimizing their potential discharge into the environment. Such strategies to reduce toxicity and exposure enable sustainable application of ENMs, such that the environmental benefits could outweigh the risks if managed properly. Engineered nanomaterials (ENMs) have numerous environmental applications, such as in water treatment and reuse. This Review explores the trade-offs between the risks and benefits of environmental ENMs, and highlights that the environmental and health risks of ENMs are relatively low when used responsibly.","PeriodicalId":18921,"journal":{"name":"Nature Reviews Earth & Environment","volume":"5 8","pages":"572-587"},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782285","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}
