Available georeferenced environmental layers are facilitating new insights into global assets and their vulnerability to anthropogenic inputs. Geographically gridded data of agricultural pesticides crucial assess human ecosystem exposure potential recognised toxicants. However, inventories often sparse over time by region, mostly report aggregated classes active ingredients, generally fragmented across local or government authorities, thus hampering an integrated analysis pesticide risk....
Degraded plastic debris has been found in nearly all waters within and nearby urban developments as well the open oceans. Natural removal of suspended microplastics (MPs) by deposition is often limited their excess buoyancy relative to water, but this can change with attachment biological matter. The extent which attached ballast affects MP dynamics still not characterised. Here, we experimentally demonstrate using a novel OMCEC (Optical Measurement CEll colonisation) system that fraction...
In modern agriculture, pesticides are used in combinations to protect crops. The co-existence of multiple soil can threaten the biodiversity that maintains ecosystem services, hence further posing a long-term risk on food security. Here, we introduce an assessment global contamination by residue pesticide mixtures nine cropping systems using fully mechanistic, spatially explicit, and time-resolved model at 0.5° × spatial resolution (approximately 55 km equator) fed with georeferenced...
Abstract CROPGRIDS is a comprehensive global geo-referenced dataset providing area information for 173 crops the year 2020, at resolution of 0.05° (about 5.6 km equator). It represents major update Monfreda et al . (2008) (hereafter MRF), most widely used geospatial previously available, covering 175 with reference 2000 10 spatial resolution. builds on originally provided in MRF and expands it using 27 selected published gridded datasets, subnational data 52 countries obtained from National...
Abstract Many countries have implemented policies to reduce the use of chemical inputs in agriculture. However, these face many obstacles that limit their effectiveness. The purpose this paper is review main challenges associated with reducing agriculture and propose potential solutions. Our analysis, based on a literature linking agronomy economics, shows several agronomic options proven effective or mitigating negative impacts. We argue organization agri-food system itself major barrier...
Anthropogenic activities have substantially enhanced the loadings of reactive nitrogen (Nr) in Earth system since pre-industrial times
There is an urgent need to reduce the environmental risk of pesticide pollution worldwide. We here explore national leverage points, using a novel dataset 21.4 million georeferenced grid cells and spatial regression discontinuity design. Our analysis lets us separate how much cross-country differences in are caused by countries' agricultural systems policies explained other factors, such as between countries for example (e.g. pest pressures). estimate that third global policies. The main...
Abstract Since the 1940s, pesticide-intensive crop protection has sustained food security but also caused pervasive impacts on biodiversity, environmental integrity and human health. Here, we employ a systematic literature review to structurally analyze pest management science in 65 developing countries. Within corpus of 3,407 publications, find that taxonomic coverage is skewed towards subset 48 herbivores. Simplified contexts are commonplace: 48% studies performed within laboratory...
Trifluralin is a widely used dinitroaniline herbicide, which can persist in the environment and has substantial ecotoxicity, especially to aquatic organisms. very insoluble water (0.22 mg/L at 20 °C) highly volatile (vapor pressure of 6.7 mPa °C); these physicochemical properties determine large part its environmental fate, includes rapid loss from soils if surface-applied, strong binding soil organic matter, negligible leaching into water. The trifluralin structure contains tertiary amino...
Abstract Pesticides are well-recognised pollutants that threaten biodiversity and ecosystem functioning. Here we quantify the environmental footprints of pesticide use for 82 countries territories eight broad regions using top-down multi-region input-output analysis. Pesticide expressed as hazard loads body weight (bw) non-target organisms required to absorb residues without experiencing adverse effects. We show world’s consumption in 2015 resulted 2 Gt-bw footprints. Of these, 32% traded...
Abstract. Despite recent advancements in cloud processing and modelling the increasing availability of high spectral- temporal- resolution satellite imagery, mapping spatial distribution crop types remains a challenging task. Here, we present CROPGRIDS – comprehensive global, geo-referenced dataset providing information on areas for 173 crops circa year 2020, at 0.05° (~5.55 km equator). It represents major update Monfreda et al. (2008) dataset, most widely used geospatial previously...
Abstract As core constituents of healthy diets, fruits are often cultivated in temporally stable and structurally complex ecosystems that harbor high levels biodiversity. However, high-intensity orchard management can lessen the human environmental health benefits fruticulture. In present article, we argue increased emphasis on biological control could contribute to preventative fruit pests, weeds, diseases, resulting pesticide phasedown. Carefully calibrated increase provision ecosystem...
Reducing environmental pressure from food systems is critical to limiting degradation and the risk of irreversibly destabilizing Earth system, but an integrated framework that sets out safe operating space for lacking. We assess current state across all Planetary Boundaries and propose Food System Boundaries, which are specific shares Planetary Boundaries delineating limits systems. Our findings reaffirm single largest driver Boundary transgressions, dominating at least...
Soil contamination by metals and metalloids (metal[loid]s) is a global issue with significant risks to human health, ecosystems, food security. Accurate risk assessment depends on understanding metal(loid) mobility, which dictates bioavailability environmental impact. Here we show theory-guided machine learning model that predicts soil fractionation across the globe. Our identifies total content organic carbon as primary drivers of mobility. We find 37% world's land at medium-to-high...
Abstract Wetlands play a key role in regulating global greenhouse gas (GHG) emissions but anthropogenic impacts on nutrients may severely alter this balance. Recent assessments indicate that almost 22% of the wetland area be affected by agricultural runoff. In work, we developed and applied dynamic mechanistic reaction network model soil organic matter linking carbon (C), nitrogen (N), sulfur (S) cycles at 0.5° × spatial resolution across globe. The was used to estimate GHG nutrient...
