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 has become a major constraint to socio‐economic development and threat livelihood in increasing parts of the world. Since late 1980s, water research attracted much political public attention. We here review variety indicators that have been developed capture different characteristics scarcity. Population, availability, use are key elements these indicators. Most progress made last few decades on quantification availability by applying spatially explicit models....
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 An increasing amount of high-resolution global spatial data are available, and used for various assessments. However, key economic human development indicators still mainly provided only at national level, downscaled by users gridded analyses. Instead, it would be beneficial to adopt sub-national administrative units where supplemented necessary. To this end, we present gap-filled multiannual datasets in form Gross Domestic Product (GDP) Human Development Index (HDI). provide a...
In this letter we analyse the temporal development of physical population-driven water scarcity, i.e. shortage, over period 0 AD to 2005 AD. This was done using population data derived from HYDE dataset, and resource availability based on WaterGAP model results for 1961–90. Changes in historical resources were simulated with STREAM model, forced by climate output ECBilt–CLIO–VECODE model. The crowding index, Falkenmark stress indicator, used identify shortage 284 sub-basins. Although our...
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...
Abstract. Global agricultural production is heavily sustained by irrigation, but irrigation system efficiencies are often surprisingly low. However, our knowledge of mostly confined to rough indicative estimates for countries or regions that do not account spatiotemporal heterogeneity due climate and other biophysical dependencies. To allow refined global water use, saving productivity potentials constrained processes also non-trivial downstream effects, we incorporated a process-based...
Traditionally, people have inhabited places with ready access to fresh water. Today, over 50% of the global population lives in urban areas, and water can be directed via tens kilometres pipelines. Still, however, a large part world's is directly dependent on natural freshwater sources. So how are related location bodies today? We present high-resolution analysis close present-day populations live surface freshwater. aim increase understanding relationship between places, distance bodies,...
Abstract. The transboundary Mekong River is facing two ongoing changes that are expected to significantly impact its hydrology and the characteristics of exceptional flood pulse. rapid economic development riparian countries has led massive plans for hydropower construction, projected climate change alter monsoon patterns increase temperature in basin. aim this study assess cumulative these factors on within next 20–30 yr. We downscaled output five general circulation models (GCMs) were...
Significance El Niño Southern Oscillation (ENSO) affects hydrological processes around the globe. However, little is known about its influence on socioeconomic impacts of flooding (i.e., flood risk). We present, to our knowledge, first global assessment ENSO’s risk in terms economic damage and exposed population gross domestic product. show that reliable anomalies exist during ENSO years basins spanning almost half Earth’s surface. These results are significant for flood-risk management....
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...
ABSTRACT The human influence on the global hydrological cycle is now dominant force behind changes in water resources across world and regulating resilience of Earth system. rise pressures freshwater par with other anthropogenic system (from climate to ecosystem change), which has prompted science suggest that humanity entered a new geological epoch, Anthropocene. This paper focuses critical role for social‐ecological systems scales, by avoiding major regime shifts away from stable...
Abstract The Tonle Sap Lake of Cambodia is the largest freshwater body Southeast Asia, forming an important part Mekong River system. lake has extremely productive ecosystem and operates as a natural floodwater reservoir for lower Basin, offering flood protection assuring dry season flow to Delta. In light accelerating pace water resources development within Basin anticipation potentially significant hydrological impacts, it critical understand overall hydrologic regime Lake. We present here...
