Abstract Water availability is a major factor constraining humanity's ability to meet the future food and energy needs of growing increasingly affluent human population. plays an important role in production energy, including renewable sources extraction unconventional fossil fuels that are expected become players security. The emergent competition for water between systems recognized concept “food‐energy‐water nexus.” nexus made even more complex by globalization agriculture rapid growth...
We advance the notion of agricultural economic water scarcity to identify where irrigation expansion may increase food production.
Significance Water’s ability to generate value in irrigated agriculture remains poorly quantified at the global scale. The valuation of irrigation water is an important piece information not only for agribusiness investors interested acquisition land and entitlements but also farmers rural communities that are negotiating with such investors. To make informed decision about or relinquishment rights investments infrastructure there a need better understanding generated by using methods rely...
Abstract Meeting the increasing global demand for agricultural products without depleting limited resources of planet is a major challenge that humanity facing. Most studies on food security do not make projections past year 2050, just as climate change and are expected to intensify. Moreover, account water sustainability limits irrigation expansion presently rainfed areas. Here we perform an integrated assessment considers range factors affecting future production throughout 21st century....
Water is a major factor limiting crop production in many regions around the world. Irrigation can greatly enhance yields, but local availability and timing of freshwater resources constrains ability humanity to increase food production. Innovations irrigation infrastructure have allowed utilize previously inaccessible water resources, enhancing withdrawals for agriculture while increasing pressure on environmental flows other human uses. While substantial additional will be required support...
Climate change is expected to affect crop production worldwide, particularly in rain-fed agricultural regions. It still unknown how irrigation water needs will a warmer planet and where freshwater be locally available expand without depleting resources. Here, we identify the cropping systems that hold greatest potential for investment expansion because likely suffice demand. Using projections of renewable availability demand under warming scenarios, target regions may sustain climate change....
Abstract The increasing global demand for farmland products is placing unprecedented pressure on the agricultural system and its water resources. Many regions of world, that are affected by a chronic scarcity relative to their population, strongly depend import commodities associated embodied (or virtual ) water. globalization through trade (VWT) leading displacement use disconnection between human populations resources they rely on. Despite recognized importance these phenomena in reshaping...
Abstract Recent studies have highlighted the reliance of global food production on unsustainable irrigation practices, which deplete freshwater stocks and environmental flows, consequently impair aquatic ecosystems. Unsustainable is driven by domestic international demand for agricultural products. Research consequences trade has often concentrated displacement pollution land use, while effect water sustainability drying over-depleted watercourses seldom been recognized quantified. Here we...
The European technical potential for biogenic carbon dioxide removal is assessed considering seven different BECCS configurations that do not require purpose-grown bio-energy plantations.
Low-carbon hydrogen is an essential element in the transition to net-zero emissions by 2050. Hydrogen production from biomass a promising bio-energy with carbon capture and storage (BECCS) scheme that could produce low-carbon generate dioxide removal (CDR) envisioned be required offset hard-to-abate emissions. Here, we design BECCS supply chain for quantify, at high spatial resolution, technical potential CDR Europe. We consider sustainable feedstocks have minimal impacts on food security...
Abstract Irrigated agriculture accounts for ∼90% of anthropogenic freshwater consumption, is deployed on 22% cultivated land, and provides 40% global food production. Expanding irrigation onto currently underperforming rainfed croplands crucial to meet future demand without further agricultural expansion associated encroachment natural ecosystems. Establishing also a potential climate adaptation solution alleviate heat- water-stress crops reduce variability extremes. Despite being one the...
Agriculture is fundamental to all three pillars of sustainability, environment, society, and economy. However, the definition sustainable agriculture capacities measure it remain elusive. Independent transparent measurements national sustainability are needed gauge progress, encourage accountability, inform policy. Here, we developed a Sustainable Matrix (SAM) quantify performance indicators in investigate trade-offs synergies based on historical data for most countries world. The results...
The chemical industry is responsible for about 5% of global CO2 emissions and key to achieving net-zero targets. Decarbonizing this industry, nevertheless, faces particular challenges given the widespread use carbon-rich raw materials, need high-temperature heat, complex value chains. Multiple technology routes are now available producing chemicals with based on biomass, recycling, carbon capture, utilization, storage. However, extent which these viable respect local availability energy...
Proposals for achieving net-zero emissions by 2050 include scaling-up electrolytic hydrogen production, however, this poses technical, economic, and environmental challenges. One such challenge is policymakers to ensure a sustainable future the environment including freshwater land resources while facilitating low-carbon production using renewable wind solar energy. We establish country-by-country reference scenario demand in compare it with water availability. Our analysis highlights...
Abstract Irrigation is a land management practice with major environmental impacts. However, global energy consumption and carbon emissions resulting from irrigation remain unknown. We assess the worldwide associated irrigation, while also measuring potential reductions achievable through adoption of efficient low-carbon practices. Currently, contributes 216 million metric tons CO 2 consumes 1896 petajoules annually, representing 15% greenhouse gas utilized in agricultural operations....
Abstract Hydrogen will play a key role in decarbonizing economies. Here, we quantify the costs and environmental impacts of possible large-scale hydrogen economies, using four prospective demand scenarios for 2050 ranging from 111–614 megatonne H 2 year −1 . Our findings confirm that renewable (solar photovoltaic wind) electrolytic production generates at least 50–90% fewer greenhouse gas emissions than fossil-fuel-based counterparts without carbon capture storage. However, could still...
Hydropower and irrigation are essential for achieving human development objectives climate mitigation adaptation. These sectors depend on the same grey infrastructure, such as dammed reservoirs, which has created negative socio-ecological externalities sectoral conflicts in past. Yet, future needs infrastructure both their interdependencies remain unclear. We address this gap by applying data-fusion machine-learning approaches provide a comprehensive global overview new dataset that...
Abstract The current centralized configuration of the ammonia industry makes production nitrogen fertilizers susceptible to volatility fossil fuel prices and involves complex supply chains with long-distance transport costs.
