The global demand for water, energy and food is driven by rapid population increase, urbanization, and climate change and it is estimated to increase by over 50% by 2050, compared with the 2015 level (Ferroukhi et al., 2015).This will pose a huge pressure on existing water, energy and food systems, which have already been constrained due to the competing
The water–energy–food nexus is a complex system where balancing the trade-offs across water, energy, and food sectors is especially difficult in resource-deficient areas. The Yellow River Basin is an area in which water shortages lead to conflicts among water, energy, and food resources. Thus, investigating the evolution state and spatial characteristics of the
Water-Energy Nexus. Review of the recent literature shows that only a few reviews have been carried out so far on WEN [3, 14, 15].Some study focuses on the classification of the method types like profit-cost assessment, physical model, and optimization management approach [], while others focus on a single sector or only one task in an industry.Many of them

Fig. 1 demonstrates that CESNeX responds on both the supply and demand sides by receiving nexus variables from the water and food subsystems and parameters, management, and independent variables. On the supply side, this demonstrates the net head of the reservoir, the flow through the turbine, and the water consumption of thermal power plants.
The energy-water-food nexus was born out of the necessity to balance the various resources of the ecosystem amidst growing uncertainties [5].The concept was first discussed in 2008 at the World Economic Forum in Davos, Switzerland where the interconnections between the energy-water-food nexus was first identified as a key parameter in addressing the global development
Relying on secondary data, the paper argues that while the existing policy initiatives have increased food production to a certain extent, the demand for water and energy has also increased
The food production system, of sustainability governance, from local to global levels, is confronted with the complexity of the diverse set of agricultural, biological, aquaculture, environmental, technological, and socioeconomic problems that needs to be understood and managed, aiming at a sustainable development (Bala et al., 2017).Therefore, it is essential to
The nexus between water, energy, and food has recently evolved as a resource-management concept to deal with this intimately interwoven set of resources, their complex interactions, and the growing and continuously changing internal and external set of influencing factors, including climate change, population growth, habits and lifestyles alternations, and the
Water is necessary for life, food is essential for human survival, and energy is the driving force of socioeconomic development in the modern age (Frappart, 2013, Le and Nguyen, 2019, Xia et al., 2022).These resources are intrinsically connected, and it is necessary to take water, energy and food as a whole, i.e., the water-energy-food (WEF) nexus (Raya-Tapia et
The Water-Energy-Food Nexus has been promoted by a number of prominent and influential global policy actors over the last couple of years. Increasingly, the concept has emerged as a major research, policy and planning instrument to govern and address demand and supply challenges across four main development sectors: water, energy, food and

In Fig. 2, the proposed design starts by treating brackish water using RO membrane separation technology, powered by an on-grid 10-kW photovoltaic solar panel.The permeate (freshwater) from the RO facility is divided into two parts. The first part is directed to an aquaculture fishpond, where the fish effluents are used as irrigation water for
A review of different methods and frameworks of the water-energy-food nexus was done in this article to give a detailed repository of information on existing approaches and advocate the development of a more holistic quantitative nexus method. P. T., Bazilian, M., Davis, R., & Macknick, J. (2014). Planning for Algal Systems: An Energy-Water
With the production of food taking up 30% of our energy consumption and up to 70% of our freshwater bodies [1], we must become more efficient in the production of our food and more so, we must use the produced food wisely. The food-energy-water nexus describes the links between food, water, and energy and how undertakings of each affect the others.
Dr Janez Sušnik, from the IHE Delft Institute for Water Education and NEXOGENESIS Coordinator, guides us through the use of machine learning for improving policy advice in the water-energy-food-ecosystems nexus. Water, energy, and food (WEF) form a coherent interconnected system often referred to as the WEF nexus (Hoff, 2011).
Implications for the Food-Energy-Water Nexus. While impacts varied by plant type, the researchers found that the agrivoltaic systems held promising implications for food production, water savings, and renewable energy production. water-use efficiency was 65% greater and total fruit production doubled in the agrivoltaic system Water savings
