Recognizing culture, and diverse sources of knowledge, can improve assessments
Ecosystem services, the benefits that people obtain from ecosystems, are a powerful lens through which to understand human relationships with environment and design environmental policy. The explicit inclusion of beneficiaries makes values intrinsic ecosystem services; whether or not those monetized, services framework provides way assess trade-offs among alternative scenarios resource use land- seascape change. We provide an overview functions responsible for producing terrestrial...
Achieving sustainable global food security is one of humanity's contemporary challenges. Here we present an analysis identifying key "global leverage points" that offer the best opportunities to improve both and environmental sustainability. We find a relatively small set places actions could provide enough new calories meet basic needs for more than 3 billion people, address many impacts with consequences, focus waste reduction on commodities greatest impact security. These points in system...
Despite broad recognition of the value goods and services provided by nature, existing tools for assessing valuing ecosystem often fall short needs expectations decision makers. Here we address one most important missing components in current toolbox: a comprehensive generalizable framework describing water quality-related services. Water quality is misrepresented as final service. We argue that it actually an contributor to many different services, from recreation human health. present...
The magnitude and pace of global change demand rapid assessment nature its contributions to people. We present a fine-scale modeling current status future scenarios for several contributions: water quality regulation, coastal risk reduction, crop pollination. find that where people's needs are now greatest, nature's ability meet those is declining. Up 5 billion people face higher pollution insufficient pollination nutrition under land use climate change, particularly in Africa South Asia....
Irrigation consumes more water than any other human activity, and thus the challenges of sustainability food security are closely linked. To evaluate how resources used for production, we examined global patterns productivity—food produced (kcal) per unit (l) consumed. We document considerable variability in crop productivity globally, not only across different climatic zones but also within zones. The least productive systems disproportionate freshwater consumers. On precipitation-limited...
Agricultural trade plays an important role in global food security and resource sustainability. Global commodities is worth more than US$520 billion per year, could feed approximately two people, uses about 13% of worldwide cropland pasture, has geographically concentrated irrigation water demands. However, researchers rarely compare these monetary, nutritional, metrics, which limits our ability to holistically evaluate the drivers implications trade. We found that each metric suggests...
We present an improved water-scarcity metric we call water depletion, calculated as the fraction of renewable consumptively used for human activities. employ new data from WaterGAP3 integrated global resources model to illustrate depletion 15,091 watersheds worldwide, constituting 90% total land area. Our analysis illustrates that moderate at annual time scale is better characterized high a monthly and are thus able integrate seasonal dry-year into metric, providing more accurate depiction...
Significance Understanding and tracking nature’s contributions to people provides critical feedback that can improve our ability manage earth systems effectively, equitably, sustainably. Declines in biodiversity ecosystem functions over the past 50 y have decreased of nature contribute quality life. Changes technology adaptation social has partially offset negative impacts environmental change on life, but downward trends still occurred for many categories contributions.
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...
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 Causal effects of biodiversity on ecosystem functions can be estimated using experimental or observational designs — that pose a tradeoff between drawing credible causal inferences from correlations and generalizable inferences. Here, we develop design reduces this revisits the question how plant species diversity affects productivity. Our leverages longitudinal data 43 grasslands in 11 countries approaches borrowed fields outside ecology to draw data. Contrary many prior studies,...
Ecosystem characteristics and processes provide significant value to human health well-being, there is growing interest in quantifying those values. Of particular are water-related ecosystem services the incorporation of their into local regional decision making. This presents multiple challenges opportunities hydrologic-modeling community. To motivate advances water-resources research, we first present three common contexts that draw upon an ecosystem-service framework: scenario analysis,...
Cities around the world are struggling to access additional water supplies support their continued growth because freshwater sources becoming exhausted. Half of all cities with populations greater than 100,000 located in water-scarce basins, and these basins agricultural consumption accounts for more 90% depletions. In this paper we review development histories four major cities: Adelaide, Phoenix, San Antonio Diego. We identify a similar pattern cities, which begins exhaustion local surface...
