With global warming, the contradiction between supply and demand of water resources is increasingly prominent in arid areas. Enhancing resource management an important way to alleviate shortage ecological improve ecosystem services river basins. However, previous studies have rarely conducted comprehensive function zoning using two aspects: category (quantity) strength change (quality), based on changes services. In this regard, scientific problems need be solved:(1) quantifying temporal spatial (2) conducting terms quantity quality. To answer these questions, we took upper middle reaches Tarim River Basin China as study area. According eco-environmental characteristics basins, measured four key indices: carbon storage (CAS), evapotranspiration (ET), temperature vegetation dryness index (TVDI) groundwater depth (GWD). We used related model quantitatively analyze distribution indicators aggregation increases decreases. Reclassify tool ArcGIS 10.5 classify areas with more than zones high-quantity zones. factor analysis, combined Quantile, divide service quality into high-quality low-quality Considering services, divided important, general, sensitive fragile Based results during 2000–2018, restoration was determined. correlation analysis basic drivers indicators.

The Water Energy Food nexus is a powerful topic in agricultural systems to elucidate threats biodiversity conservation and culture. This paper aimed recapitulate thinking research, focusing on social-ecological transitions of agriculture management within the Water-Energy-Food nexus. We developed systematic review bibliometric analysis derived from 529 documents Scopus database. ToS method identified total 81 relevant information sample (529) categorised into roots (10), trunks (9) leaves (62). situates types, focus, highlights regarding prevalent thematic research areas such as "Food Nexus", "Environmental Flows", "Sustainability", "Transitions", "Governance". Our results suggest that future should focus "Water-Energy-Food-Biodiversity" propose transdisciplinary approach state sustainability at landscape level.

The Water–Energy–Food Nexus in European Countries: A Review and Future Perspectives

Sustainability, Journal Year: 2023, Volume and Issue: 15(6), P. 4960 - 4960

Published: March 10, 2023

The interaction between water, energy, and food as the water–energy–food (WEF) nexus has drawn much attention recently to solve upcoming uncertainty in security. aim of this study is investigate status WEF European countries. It indicated that largest studies (among 27 countries) have been conducted Spain Italy. confirmed there a large number water-stressed countries while are few on water-abundant (Slovakia Luxembourg). Based existing research, majority focused energy production. highlighted most were water quantity aspects (rarely related quality aspects) energy; however, other resources including land, climate, ecosystem, soil, environment received little attention. migration people result climate change not considered. Moreover, lack common standard frameworks for assessment. Therefore, we suggest approach produce cross-sectoral holistic evaluation (quantity quality)–energy–food–land–climate (WqEFLC) takes into consideration circular economy.

Insights on Water and Climate Change in the Greater Horn of Africa: Connecting Virtual Water and Water-Energy-Food-Biodiversity-Health Nexus

Sustainability, Journal Year: 2021, Volume and Issue: 13(11), P. 6483 - 6483

Water is the key limiting factor in socioeconomic and ecological development, but it adversely affected by climate change. The novel virtual water (VW) concept water, energy, food, biodiversity, human health (WEFBH) nexus approach are powerful tools to assess sustainability of a region through lens Climate change-related challenges complex intertwined. This paper analyzed significant WEFBH sectors using multicriteria decision-making (MCDM) analytic hierarchy process (AHP) model. AHP model demonstrated quantitative relationships among indicators Greater Horn Africa countries. Besides, net VW imports footprints major staple crops were assessed. composite indices varied from 0.10 0.14. footprint increasing period period. results also revealed that most countries study area facing domains unsustainability due weak planning or improper management strategies. strong policy constancy sector vital for dissociating high-water consumption crop production, environmental, system.

The SDGs, Ecosystem Services and Cities: A Network Analysis of Current Research Innovation for Implementing Urban Sustainability

Sustainability, Journal Year: 2021, Volume and Issue: 13(24), P. 14057 - 14057

Ecosystem services are essential for cities and key factors in achieving many of the Sustainable Development Goals (SDGs). Such best delivered through green infrastructure, which works resourceful, multifunctional, synergistic, environmentally sensitive ways to deliver ecosystem provide alternative cleaner pathways delivery multiple urban services. It is unclear if current research supports necessary linkages between services, cities, infrastructure order achieve SDGs. To answer this question, we conducted a systematic review analysing 3392 studies on SDGs from WoS database. The contents 66 those with relevance were reviewed depth. We applied network-analytic methods map relationships different knowledge clusters (1) across time, (2) disciplines, (3) relation cities. results our analysis show that have developed stronger networks 2010–2018, but has not been sustained. Further, whilst now occupies central place literature, only shows tentative links both green-infrastructure research. literature remains peripheral challenge sustainable transitions. conclude when it comes SDGs, articles typically consider independently infrastructure. suggests generally considered as conventional infrastructures. address serious shortcoming, recommend transdisciplinary approaches link 2030 global sustainability agenda.

Abstract In 2018, Albrecht et al., published a comprehensive review of water‐energy‐food nexus literature, coming to five main criticisms in research based on their perception the state‐of‐the‐art. The central conclusions that together with consideration more recent initiatives form basis for this critical review. current state research, and particular modeling is examined updated reflect advances, correct some misperceptions, put enterprise into context larger epistemological issues. are: considerable growing diversity studies necessarily precludes one‐size‐fits‐all approach, indeed it has never been an objective develop “grand unified theory or model.” A lack “fundamental equations” between many parameters hinders full quantification all linkages, though data‐driven, stochastic, agent‐based approaches offer useful avenues further development. use qualitative social science methods rapidly gaining traction, especially when blended quantitative modeling. Great progress made attempting break disciplinary siloes, considering integrated assessment models system dynamics models. paper concludes reflections how date could inform new initiatives, such as Sustainable Urban Nexus Project, future work generally. These are summarized follows: Integration ecosystem services relationships should be priority near‐future efforts. Social techniques efforts, local stakeholder engagement, success impact recommendations. Policy‐relevant recommendations starting developed. Greater focus, involvement, will policy studies.

Water, energy, and food are all essential components of human societies. Collectively, their respective resource systems interconnected in what is called the “nexus”. There growing consensus that a holistic understanding interdependencies trade-offs between these sectors other related critical to solving many global challenges they present. While nexus research has grown exponentially since 2011, there no unified, overarching approach, implementation concepts remains hampered by lack clear case studies. Here, we present results collaborative thought exercise involving 75 scientists summarize them into 10 key recommendations covering: most issues today, emerging themes, where future efforts should be directed. We conclude community practice promote open communication among researchers, maintain share standardized datasets, develop applied studies will facilitate transparent comparisons models encourage adoption approaches practice.
