“…In weak sustainability [29], resources are not the only focus of sustainable development, the human factor affects sustainable development either directly or indirectly because the population is the principle component in the sustainable development system and the continuum in production and consumption [30]. Since the security in water, energy, and food is interwoven with human, economic, and environmental sustainability [31,32], there is strong interdependence between the WEF-Nexus and the population system, economic system, and environmental system (Figure 1). …”

An explanation and quantification of the water-energy-food nexus (WEF-Nexus) is important to advance our understanding of regional resource management, which is presently in its infant stage. Evaluation of the current states, interconnections, and trends of WEF-Nexus, in cities, has largely been ignored due to quantification hurdles and the lack of available data. Based on the interaction of WEF-Nexus with population system, economic system, and environmental system, this paper builds the input output index system at the city level. Using the input output index system, we evaluate the WEF-Nexus input-output efficiency with the data envelopment analysis (DEA) model. We regard the decision making unit as a "black box", to explore the states and trends of WEF-Nexus. In the empirical study based on data from China, we compare the input-output efficiency of WEF-Nexus in 30 provinces across China, from 2005 to 2014, to better understand their statues and trends of the input-output efficiency holistically. Together with the Malmquist index, factors leading to regional differences in the fluctuation of input-output efficiency are explored. Finally, we conclude that the DEA model indicates the regional consumption of WEF resources in the horizontal dimension and the trends in vertical dimension, together with the Malmquist index, to explain the variations for proposing specific implications.

“…Discussions are under way to improve existing governance and policy systems by adopting the WEF nexus. The improvement of existing governance includes a broad involvement and collaboration of planners and policymakers (financial, institutional, technical, and intellectual sectors) to build a responsible and supportive governance at local, national, and supranational level (Bhaduri et al, 2015). On the policy side, Gain et al (2015) suggested the integration of the existing policies of each sector, rather than creating a new exclusive policy.…”

“…Hence, it requires the participation of stakeholders to conduct international collaboration. Finally, the nexus governance should have a continuous innovation, political support, constant monitoring, and transparent governance principles to achieve sustainable development and reduce competition or conflicts (Bhaduri et al, 2015).…”

Water, energy, and food nexus: review of global implementation and simulation model development

2017

Water, energy, and food (WEF) have complex interconnections. Water is required to produce energy, while energy is needed for water extraction, treatment, and distribution. The food sector requires water and energy to produce food products, while fertilizer and pesticide from farmland have a negative impact on water quality; however, biomass is a potential alternative energy source. Understanding these interconnections will help determine the developmental framework that connects all of the elements. Some global regions have implemented a variety of sustainable management concepts to manage the natural resources, however, mainly for an individual resource. Furthermore, various computer models have been developed to estimate the interdependency of each resource and to quantify future requirements of WEF; the limitations of current models have opened opportunities for development through the addition of components and features such as feedback analysis, optimization, and visualization. We reviewed the literature to determine the present state of the WEF nexus, especially its global implementation and simulation model. We concluded that the involvement of stakeholders, integration of policies, and development of a nexus simulation model are required for successful implementation of the WEF nexus, which is an emerging issue for a sustainable resources' management.

“…For example, they illustrate the water flows needed to irrigate land and the energy flows required for the production of ethanol. Alternatively, papers focus on the social side of the equation and discuss for instance how institutional coordination can help to establish a nexus between WEF (see e.g., Scott et al 2011;Harvey 2014;Foran 2015;Bhaduri et al 2015;Gain et al 2015;Halbe et al 2015;Biggs et al 2015;Smajgl et al 2016;Boas et al 2016). Very few articles or literature strands examine both material and social dimensions when understanding or assessing the nexus of WEF.…”

“…In the quest of the nexus, there are many hurdles and complexities related to policy and decisionmaking to overcome. These may concern limitations resulting from administrative boundaries (city, regional or national scale); the scale of the management of WEF (municipal, regional or national) (Bhaduri et al 2015;Biggs et al 2015;Weitz et al 2017); and disarticulation in the policy and decision-making (Gain et al 2015). Actors in the quest of making the nexus thus constantly have to coframe sustainability related goals, co-define problems, or contest perceptions with regard to effective policy making or even what a nexus governance of WEF is like.…”

The nexus between water, energy and food in cities: towards conceptualizing socio-material interconnections

Sustainable use and supply of natural resources dedicated to feeding urban life are becoming increasingly complex in a time of rapid urbanization and climate change. Sustainable governance of Water-Energy-Food (WEF) requires innovative and cross-sectorial systems of provisioning. However, practitioners have often treated WEF as separate domains, while ignoring their interconnectedness. What is missing is an 'Urban Nexus' perspective, which assumes that environmental flows of WEF interact and relate to one another in achieving urban sustainable development. This paper contributes to theorizing the urban nexus and to understand its emergence and governance from a more socio-material perspective. It offers a conceptual framework that helps to shed light on the social and material flows shaping connections between the sectors of WEF, and the actors facilitating these connections. The paper suggests that switchers and programmers link and configure the socio-material flows of WEF facilitating the emergence of nexus governance networks and nexus programs. In doing so, the paper provides three examples of cities to test the conceptual framework by analyzing their main challenges and examples around the nexus. It demonstrates that material and social dimensions of WEF might not play an equal role in steering synergies or trade-offs-either material or social flows and their agents can be central in facilitating a nexus or in preventing it to take shape. The paper argues that material-focused methodologies need to be complemented with a social flows analysis that pays attention to the daily practice, policies, ideologies, networks or any kind of sociocultural meaning shaping WEF provisioning.
