Abstract The stability and resilience of the Earth system human well-being are inseparably linked 1–3 , yet their interdependencies generally under-recognized; consequently, they often treated independently 4,5 . Here, we use modelling literature assessment to quantify safe just boundaries (ESBs) for climate, biosphere, water nutrient cycles, aerosols at global subglobal scales. We propose ESBs maintaining (safe ESBs) minimizing exposure significant harm humans from change (a necessary but...
Abstract. Billions of people rely on groundwater as being an accessible source drinking water and for irrigation, especially in times drought. Its importance will likely increase with a changing climate. It is still unclear, however, how climate change impact systems globally and, thus, the availability this vital resource. Groundwater recharge important indicator availability, but it flux that difficult to estimate uncertainties balance accumulate, leading possibly large errors particular...
Abstract. Global water models (GWMs) simulate the terrestrial cycle on global scale and are used to assess impacts of climate change freshwater systems. GWMs developed within different modelling frameworks consider underlying hydrological processes, leading varied model structures. Furthermore, equations describe various processes take forms generally accessible only from individual codes. These factors have hindered a holistic detailed understanding how operate, yet such an is crucial for...
Abstract. The summer of 2018 was an extraordinary season in climatological terms for northern and central Europe, bringing simultaneous, widespread, concurrent heat drought extremes large parts the continent with extensive impacts on agriculture, forests, water supply, socio-economic sector. Here, we present a comprehensive, multi-faceted analysis extreme particular focus Germany. heatwave first affected Scandinavia mid-July shifted towards Europe late July, while Iberia primarily early...
Abstract Safe and just Earth system boundaries (ESBs) for surface water groundwater (blue water) have been defined sustainable management in the Anthropocene. Here we assessed whether minimum human needs could be met with from within individual river basins alone and, where this is not possible, quantified how much would required. Approximately 2.6 billion people live needed because they are already outside ESB or insufficient to meet ESB. 1.4 demand-side transformations required as either...
Abstract Several safe boundaries of critical Earth system processes have already been crossed due to human perturbations; not accounting for their interactions may further narrow the operating space humanity. Using expert knowledge elicitation, we explored among seven variables representing relevant food production, identifying many little in literature. We found that green water and land change affect other strongly, while land, freshwater ocean components biosphere integrity are most...
Abstract Safe and just Earth System Boundaries (ESBs) for surface groundwater (blue water) have been defined sustainable water management in the Anthropocene. We evaluate where minimum human needs can be met within ESB and, this is not possible, identify how much required. 2.6 billion people live catchments needed because they are already outside or insufficient to meet ESB. Approximately 1.4 demand side transformations required as either exceed face a decline recharge cannot A further 1.5...
Environmental life-cycle assessment (LCA) was applied to evaluate three different water systems of the sector in Copenhagen, Denmark, including technologies within supply, facilities recycling and treatment sewer overflow. In these LCA used environmental impacts each processes involved. The overall conclusion that is suitable as a decision support tool it provides holistic evaluation platform considered alternatives categorised impact categories. use this region has limitations since does...
Freshwater is fundamental to Earth system processes, yet its global dynamics are often overlooked in water governance. With half of all terrestrial precipitation originating from land evaporation, the interdependencies atmospheric moisture flows remain underrepresented policies addressing security and climate adaptation. In particular, impacts on supply chains have not been assessed so far. Therefore, we here assess interactions between network with international trade network, which...
Intact land and freshwater ecosystems are a prerequisite for limiting global warming in accordance with the Paris Agreement. However, critical co-dependence of climate mitigation outcomes dynamics tends to be neglected both research policies. Here, we suggest framework systematically quantifying indispensable requirements measures, focused on natural managed terrestrial systems upholding carbon sink. We assert that while huge volumes involved this biospheric service per se, substantial...
Agricultural areas are increasingly experiencing green water stress – i.e. soil moisture limiting crop growth – due to rising demands of an expanding world population as well climate change. While irrigation has the potential mitigate this stress, its effective implementation is often challenged by blue scarcity and lack infrastructure. In study, we apply a newly developed plant physiological index modeled global dynamic vegetation model LPJmL, that accounts for...
The Amazon rainforest, a global biodiversity hotspot and home to over 40 million people—2.2 of whom are Indigenous—plays critical role in the regulation water carbon cycles. However, its unique biocultural diversity is increasingly threatened by climate land-use changes, which could shift vegetation multi-stable forest areas savannah- or grassland-like states. Satellite-based observations, Earth system models, rainfall exclusion experiments provide evidence rainforest's...
Abstract. Numerical models are simplified representations of the real world at a finite level complexity. Global water used to simulate terrestrial part global cycle, and their outputs contribute evaluation important natural societal issues, including availability, flood risk, ecological functioning. Whilst modeling is an area science that has developed over several decades, individual model-specific descriptions exist for some models, there date been no attempt visualize ways work, using...
Abstract Atmospheric moisture flows play a vital role in the hydrological cycle, connecting evaporation sources to precipitation sinks. While high-resolution tracking models provide valuable insights, discrepancies arise comparing tracked atmospheric reanalysis data. Here we reconcile with data by means of Iterative Proportional Fitting applied UTrack dataset (averaged over 2008–2017) aggregated within countries and ocean boundaries. It corrects country-scale up 275% 225% evaporation,...

Abstract The planetary boundaries framework defines a safe operating space for humanity. To date, these have mostly been investigated separately, and it is unclear whether breaching one boundary can lead to the transgression of another. By employing dynamic global vegetation model, we systematically simulate strength direction effects different levels climate change (using output from ten phase 6 Coupled Model Intercomparison Project models CO 2 ranging 350 ppm 1000 ppm). We focus on...
