This planetary boundaries framework update finds that six of the nine are transgressed, suggesting Earth is now well outside safe operating space for humanity. Ocean acidification close to being breached, while aerosol loading regionally exceeds boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased all earlier identified as overstepped. As primary production drives system biosphere functions, human appropriation net proposed a control variable...
Reducing food losses and waste is considered to be one of the most promising measures improve security in coming decades. Food also affect our use resources, such as freshwater, cropland, fertilisers. In this paper we estimate global supply due lost wasted crops, resources used produce them. We quantify potential resource savings that could made by reducing waste. publically available databases conduct study at country level. found around quarter produced (614 kcal/cap/day) within chain...
Abstract Water scarcity is a rapidly growing concern around the globe, but little known about how it has developed over time. This study provides first assessment of continuous sub-national trajectories blue water consumption, renewable freshwater availability, and for entire 20 th century. analysed using fundamental concepts shortage (impacts due to low availability per capita) stress high consumption relative availability) which indicate difficulties in satisfying needs population overuse...
Abstract. Irrigation intensifies land use by increasing crop yield but also impacts water resources. It affects and energy balances consequently the microclimate in irrigated regions. Therefore, knowledge of extent is important for hydrological modelling, global change research, assessments resource management. Information on historical evolution lands limited. The new irrigation data set (HID) provides estimates temporal development area equipped (AEI) between 1900 2005 at 5 arcmin...
Achieving global food security is one of the major challenges coming decades. In order to tackle future we must understand past. This study presents a historical analysis availability, key elements security. By calculating national level dietary energy supply and production for nine time steps during 1965–2005 classify countries based on their self-sufficiency trade. We also look at how diets have changed this period with regard animal calories. Our results show that availability has...
Growing population and water demand have increased pressure on resources in various parts of the globe, including many transboundary river basins. While impacts upstream use downstream availability been analysed these international basins, this has not systematically done at global scale using coherent comparable datasets. In study, we aim to assess change stress due world's Water was first calculated considering only local each sub-basin based country-basin mesh, then compared with...
Abstract Fresh water—the bloodstream of the biosphere—is at center planetary drama Anthropocene. Water fluxes and stores regulate Earth's climate are essential for thriving aquatic terrestrial ecosystems, as well water, food, energy security. But water cycle is also being modified by humans an unprecedented scale rate. A holistic understanding freshwater's role Earth system resilience detection monitoring anthropogenic modifications across scales urgent, yet existing methods frameworks not...
Rapidly increasing international food trade has drastically altered the global system over past decades. Using national scale indicators, we assess two of resilience principles that directly reflect effects on systems – namely, maintaining diversity and redundancy, managing connectivity. We perform our analysis for four nutritional components: dietary energy, proteins, fat, quantity vegetables & fruits key pillars WHO recommendations. Our results indicate that, between 1987 2013, supply...
The planetary boundaries framework proposes quantified guardrails to human modification of global environmental processes that regulate the stability planet and has been considered in sustainability science, governance, corporate management. However, boundary for freshwater use critiqued as a singular measure does not reflect all types interference with complex water cycle Earth System. We suggest will be more scientifically robust useful decision-making frameworks if it is redesigned...
Abstract Human actions compromise the many life-supporting functions provided by freshwater cycle. Yet, scientific understanding of anthropogenic change and its long-term evolution is limited. Here, using a multi-model ensemble global hydrological models, we estimate how, over 145-year industrial period (1861–2005), streamflow soil moisture have deviated from pre-industrial baseline conditions (defined 5th–95th percentiles, at 0.5° grid level monthly timestep 1661–1860). Comparing two...
Water and land resources are under increasing pressure in many parts of the globe. Diet change has been suggested as a measure to contribute adequate food security for growing population. This paper assesses impact diet on blue green water footprints consumption. We first compare consumption current diets with that scenario where dietary guidelines followed. Then, we assess these by applying four scenarios which gradually limit amount protein from animal products 50%, 25%, 12.5% finally 0%...

Ensuring food security requires production and distribution systems function throughout disruptions. Understanding the factors that contribute to global system's ability respond adapt such disruptions (i.e. resilience) is critical for understanding long-term sustainability of human populations. Variable impacts shocks on supply between countries indicate a need national-scale resilience indicators can provide comparisons. However, methods tracking changes in have had limited application...
The insufficiency of water resources to meet the needs food production is a pressing issue that likely increase in importance future. Improved understanding historical developments can provide basis for addressing future challenges. In this study we analyse how hydroclimatic variation, cropland expansion and evolving agricultural practices have influenced potential self-sufficiency within last century. We consider unit (FPU) experienced green–blue (GBW) scarcity if local renewable green (in...
While a growing proportion of global food consumption is obtained through international trade, there an ongoing debate on whether this increased reliance trade benefits or hinders security, and specifically, the ability systems to absorb shocks due local regional losses production. This paper introduces model that simulates short-term response supply shock originating in single country, which partly absorbed decreases domestic reserves consumption, transmitted adjustment flows. By applying...

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. Human actions and climate change have drastically altered river flows across the world, resulting in adverse effects on riverine ecosystems. Environmental (EFs) emerged as a prominent tool for safeguarding ecosystems, but at global scale, assessment of EFs is associated with high uncertainty related to hydrological data EF methods employed. Here, we present novel, in-depth using environmental flow envelopes (EFEs). Sub-basin-specific EFEs are determined approximately 4400...
International trade plays a fundamental role in today's globalized food system, however, trade-related disruptions to national supply have become increasingly prevalent. Although self-sufficiency and the resilience of domestic production are both discussed, they rarely investigated tandem. This hinders our understanding diversity risks supply. In this article we investigate contribution these risks, through compilation comprehensive dataset multi-indicator assessment diversity. Our results...
