“…Willis et al (2016) focused on measures of availability and accessibility of FEW resources to produce subindices for each resource that were then aggregated to a FEW index for countries globally. Other work has used a variety of techniques to explore parts of the FEW nexus such as global virtual water networks and life cycle analyses (e.g., Feng et al, 2014;Konar et al, 2011;Yuan et al, 2018) but have not stressed relationships with governance.

“…Both of these approaches overlooked governance factors, and the resources were siloed such that cross-sectoral influences (e.g., influence of water withdrawals and crop production on electricity consumed) were not considered. Other work has used a variety of techniques to explore parts of the FEW nexus such as global virtual water networks and life cycle analyses (e.g., Feng et al, 2014;Konar et al, 2011;Yuan et al, 2018) but have not stressed relationships with governance. Consistent inclusion of governance will be especially important given the potential for and consequences of the conflicts generated by scarcity of resources (Märker et al, 2018).…”

Prominent Influence of Socioeconomic and Governance Factors on the Food‐Energy‐Water Nexus in sub‐Saharan Africa

2019

Food, energy, and water (FEW) are primary resources required for human populations and ecosystems. Availability of the raw resources is essential, but equally important are the services that deliver resources to human populations, such as adequate access to safe drinking water, electricity, and sufficient food. Any failures in either resource availability or FEW resources-related services will have an impact on human health. The ability of countries to intervene and overcome the challenges in the FEW domain depends on governance, education, and economic capacities. We distinguish between FEW resources, FEW services, and FEW health outcomes to develop an analysis framework for evaluating interrelationships among these critical resources. The framework is applied using a data-driven approach for sub-Saharan African countries, a region with notable FEW insecurity challenges. The data-driven approach using a cross-validated stepwise regression analysis indicates that limited governance and socioeconomic capacity in sub-Saharan African countries, rather than lack of the primary resources, more significantly impact access to FEW services and associated health outcomes. The proposed framework helps develop a cohesive approach for evaluating FEW metrics and could be applied to other regions of the world to continue improving our understanding of the FEW nexus.

“…The LCA was one of the nexus theme tools most addressed by researchers because of its three resource functions [49,74,77,94,169]. This tool allows the identification and evaluation of all inputs that make up a life cycle of a process or product to assist in the evaluation of transfers between them, and it allows quantification of the environmental impacts correlated to the system under analysis.…”

A Literature Review to Propose a Systematic Procedure to Develop “Nexus Thinking” Considering the Water–Energy–Food Nexus

et al. 2019

There is a growing interest in the literature on the theme of the water–energy–food nexus, as there is growing recognition that sectors that share natural resources have interdependent and interconnected systems. Despite the widespread popularity of nexus thinking, it still lacks standardized procedures and methodologies to assist in its development. Therefore, this paper proposes, from a literature review, a systematic procedure to assist in the development of management models based on nexus thinking. To this end, 304 papers were analyzed using the following criteria: nexus concept, type of approach, geographic scale, elements in the nexus system, application context, and types of assessment methods and tools. The results of the review served as the basis for determining the procedure, which consisted of four steps: (a) understanding nexus thinking, (b) identification of composing variables, (c) evaluation (diagnosis and prognosis), and (d) decision-making. In addition to the standardization of these steps, the main information used to compose the procedure was organized and synthesized with a mind map.

“…As the number of elements and as nexus users commenced to unpack the nexus concept, this elegant simplicity began to reveal its intrinsic complexities leading to the proliferation of tens of unique nexus topological frameworks (ex. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]).…”

“…We reviewed a wide range of unique nexus topological frameworks (ex. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]) and identified four essential framework ingredients: (1) an organizing principle, (2) a protocol for component-component interactions, (3) modifying factors (endogenous or exogenous) that influence system interactions, and (4) a directory of system components. All current frameworks had one or more of those ingredients, but none (to our interpretation) contained all four.…”

An Organizing Principle for the Water-Energy-Food Nexus

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 dynamic prices of water, energy, and food. While an intriguing concept, the global research community is yet to identify a unifying conceptual and mathematical framework capable of adapting to integrate gathered knowledge and ensuring inclusivity by accounting for all significant interactions and feedbacks (including natural processes and anthropogenic inputs) within all nexus domains. We present an organizing roadmap for a conceptual and mathematical representation of the nexus. Our hope is that this representation will organize the nexus research and formalize a way for a generalizable framework that can be used to advance our understanding of those complex interactions, with hope that such an approach will lead to a more resilient future with sustained resources for the future generations.
