Abstract There is increased awareness that the current food system unsustainable and transformative research, development innovation in agricultural water management (AWM) are needed to transform systems under climate change. We provide an overview of research efforts, challenges, opportunities innovations improve resource sustainability, especially sector. highlight how sustainable AWM central...

Water, energy, and food are important factors affecting people’s lives socio-economic development, their production consumption processes closely related, so it is necessary to do research on input–output efficiency as a whole. The conducive promoting the effective utilization rational allocation of relevant resources in Yangtze River Economic Belt, thereby sustainable development. This study c...

‎‎In this paper‎, ‎we define fuzzy subnexuses over a nexus $N$‎. ‎Define and study the notions of the prime fuzzy subnexuses and the fractions‎‎induced by them‎. ‎Finally‎, ‎we show that if S is a meet‎‎closed subset of the set Fsub(N), ‎of fuzzy subnexuses of a nexus N‎, ‎and‎‎h= ⋀S ϵ S, ‎then the fractions S^-1 N and h^-1 N are isomorphic as meet-semilattices‎.

Energy, water, and food are facing present and future challenges triggered by climate change, population growth, human behavior, and economics. Management strategies for energy, water, and food are possible through policies, technology, and related education. However, the links between resources (energy, water, and food) and impacting factors (population increase, human behavior, economics, and...

Understanding the food-energy-water nexus is necessary to identify risks and inform strategies for nexus governance to support resilient, secure, and sustainable societies. To manage risks and realize efficiencies, we must understand not only how these systems are physically connected but also how they are institutionally linked. It is important to understand how actors who make planning, manag...

A perfect matching in an undirected graph G = (V,E) is a set of vertex disjoint edges from E that include all vertices in V . The perfect matching problem is to decide if G has such a matching. Recently Rothvoß proved the striking result that the Edmonds’ matching polytope has exponential extension complexity. Here we describe a perfect matching polytope that is different from Edmonds’ polytope...

In recent years, water-scarce regions (WSRs) have faced many challenges in order to achieve sustainable economic development. Sustainable development the agricultural sector of WSRs is possible by paying attention water-energy-food nexus (WEFN) concept. WEFN determined using consumption, physical productivity, and productivity criteria water energy resources. According goals resources, it will ...

The 10 Small Island Developing States (SIDS) of the Caribbean in this study have unsustainable water-energy-food Nexus conditions, with stress becoming more acute via climate change, population demographics and increasing tourist demands. Water resources are limited, wastewater treatment is inadequate or missing. Nature-based solutions (NBS), especially constructed wetlands, effective options f...

The goal of the Nexus Event Service is to detect state change in services including the distributed Nexus Location Service. So far only state change on an isolated location service node can be detected. This work presents a model for distributed observation of events tailored to Nexus. With this model state change in a distributed set of location service nodes can be detected.
