Abstract

Food, energy, and water (FEW) resources are all basic human needs. With population increase and economic growth, challenges on securing sufficient food, energy, and water to meet human demand are amplifying. A recent sustainable development report indicates that in 2017 there were~700 million people practicing open defecation,~785 million people lacking basic drinking water services,~820 million people undernourished (including 770 million people with severe food insecurity), and~840 million people without access to electricity (https://www.sdgindex.org/reports/sustainable-development-report-2019/). Billions of people are suffering from water and energy insecurity. Specifically, 3 billion people lacked basic handwashing facilities at home in 2017,~3 billion people had no access to clean cooking fuels and technologies in 2017, and~4.8 billion people experienced either human water security or biodiversity threats. Among the 17 Sustainable Development Goals (SDGs) approved by the United Nations in 2015, "zero hunger" (Goal 2), "affordable and clean energy" (Goal 7), and "clean water and sanitation" (Goal 6) are specifically set for food, energy, and water, respectively, while other goals are closely linked to these three resources. Food production and processing sectors are the largest water users and important energy consumers. Quantifying the complicated interdependencies among food, energy, and water is critical to achieve the SDGs (Liu et al., 2018). The FEW nexus has a large impact on human adaptation to various grand challenges, such as climate extremes and change, population growth, and water scarcity. (Fig. 1) Considerable progress has been made on identifying the grand challenges of FEW nexus and developing new approaches to managing limited FEW resources (e.g. Conway et al., 2015, Liu et al., 2017). However, effective implementation of those approaches is limited by insufficient understanding of FEW nexus tradeoffs in the context of science-policy-stakeholder interactions (Liu et al., 2017). The lack of scientific understanding further precludes development of system-level tools for overcoming policy barriers and facilitating stakeholder acceptance (Liu et al., 2018). The assessment of FEW nexus needs to move from a linear "tree" model that emphasizes disciplinary research to a "web" model that addresses interdisciplinary complexity (Liu et al., 2019). Building upon a previous special issue on FEW Nexus (Khanna et al., 2017), this virtual special issue (VSI) calls for contributions that will include data collection, tool development, and management policies for the FEW nexus. The scope includes database development, FEW interactions and modeling at various scales, comparative analysis of FEW challenges and approaches among regions/countries, FEW linkages to climate extremes and change, and practical implications for FEW policies and sustainable development. This VSI aims to catalyze information integration, develop system modeling techniques, and explore management strategies and practices for nexus-based sustainability. The papers in the VSI should fill substantial knowledge gaps in the FEW nexus and provide a roadmap for improving life-cycle management of FEW resources. Submissions that provide innovative insights into FEW research directions are encouraged. Original research articles and review papers are invited to address the following topics: • FEW nexus database development at watershed, city, regional, national , and global scales • FEW nexus case studies at watershed, city, regional, national, and global scales • Modeling and tool development for synthesis/tradeoff analysis, input-output tables, and management software of the FEW nexus • FEW nexus policies for water resources management, agricultural production, energy consumption, adaptation to climate extremes and change, ecosystem services, and greenhouse gas emissions

Food, energy, and water (FEW) resources are all basic human needs.
With population increase and economic growth, challenges on securing
sufficient food, energy, and water to meet human demand are ampli-
fying. A recent sustainable development report indicates that in 2017
there were ~700 million people practicing open defecation, ~785
million people lacking basic drinking water services, ~820 million
people undernourished (including 770 million people with severe food
insecurity), and ~840 million people without access to electricity
(https://www.sdgindex.org/reports/sustainable-development-report-
2019/). Billions of people are suffering from water and energy in-
security. Specifically, 3 billion people lacked basic handwashing facil-
ities at home in 2017, ~3 billion people had no access to clean cooking
fuels and technologies in 2017, and ~4.8 billion people experienced
either human water security or biodiversity threats.
Among the 17 Sustainable Development Goals (SDGs) approved by
the United Nations in 2015, “zero hunger” (Goal 2), “affordable and
clean energy” (Goal 7), and “clean water and sanitation” (Goal 6) are
specifically set for food, energy, and water, respectively, while other
goals are closely linked to these three resources. Food production and
processing sectors are the largest water users and important energy
consumers. Quantifying the complicated interdependencies among
food, energy, and water is critical to achieve the SDGs (Liu et al., 2018).
The FEW nexus has a large impact on human adaptation to various
grand challenges, such as climate extremes and change, population
growth, and water scarcity. (Fig. 1)
Considerable progress has been made on identifying the grand chal-
lenges of FEW nexus and developing new approaches to managing lim-
ited FEW resources (e.g. Conway et al., 2015,Liu et al., 2017). However,
effective implementation of those approaches is limited by insufficient
understanding of FEW nexus tradeoffs in the context of science-policy-
stakeholder interactions (Liu et al., 2017). The lack of scientific under-
standing further precludes development of system-level tools for over-
coming policy barriers and facilitating stakeholder acceptance (Liu et al.,
2018). The assessment of FEW nexus needs to move from a linear “tree”
model that emphasizes disciplinary research to a “web” model that ad-
dresses interdisciplinary complexity (Liu et al., 2019).
Building upon a previous special issue on FEW Nexus (Khanna et al.,
2017), this virtual special issue (VSI) calls for contributions that will
include data collection, tool development, and management policies for
the FEW nexus. The scope includes database development, FEW inter-
actions and modeling at various scales, comparative analysis of FEW
challenges and approaches among regions/countries, FEW linkages to
climate extremes and change, and practical implications for FEW po-
licies and sustainable development. This VSI aims to catalyze in-
formation integration, develop system modeling techniques, and ex-
plore management strategies and practices for nexus-based
sustainability. The papers in the VSI should fill substantial knowledge
gaps in the FEW nexus and provide a roadmap for improving life-cycle
management of FEW resources. Submissions that provide innovative
insights into FEW research directions are encouraged. Original research
articles and review papers are invited to address the following topics:
FEW nexus database development at watershed, city, regional, na-
tional, and global scales
FEW nexus case studies at watershed, city, regional, national, and
global scales
Modeling and tool development for synthesis/tradeoff analysis,
input-output tables, and management software of the FEW nexus
FEW nexus policies for water resources management, agricultural
production, energy consumption, adaptation to climate extremes
and change, ecosystem services, and greenhouse gas emissions
Impacts of supply chain management on the FEW nexus

and improved FEW production efficiencies

Food-energy-water (FEW) systems are increasingly vulnerable to natural hazards and climate change risks, yet humans depend on these systems for their daily needs, wellbeing, and survival. We investigate how adaptations related to food, energy, and water vulnerabilities are occurring and what the global community can learn about the interactions across these adaptations. We conducted a global analysis of a dataset derived from scientific literature to present the first large scale assessment (n=1,204) of evidence-based FEW-related climate adaptations. We found that the most frequently reported adaptation to FEW vulnerabilities by continent occurred in Africa (n=495) and Asia (n=492). Adaptations targeting food security are more robustly documented than those relevant to water and energy security, suggesting a greater global demand to address food security. Determining statistically significant associations, we found a network of connections between variables characterizing FEW-related adaptations and showed interconnectedness between a variety of natural hazards, exposures, sectors, actors, cross-cutting topics and geographic locations. Connectivity was found between the vulnerabilities food security, water, community sustainability and response to sea-level rise across cities, settlements, & key infrastructure sectors. Additionally, generalized linear regression models revealed potential synergies and tradeoffs among FEW adaptations, such as a necessity to synergistically adapt systems to protect food and water security and tradeoffs when simultaneously addressing exposures to consumption & production versus poverty. Results from qualitative thematic coding showcased that adaptations documented as targeting multiple exposures are still limited in considering interconnectivity of systems or applying a nexus approach in their response. These results suggest that adopting a nexus approach to future FEW-related adaptations can have profound benefits in the management of scarce resources and with financial constraints.

The purpose of this study is to explain the determinants of the process of investing in renewable energy sources (RES) from the perspective of enterprises, with particular emphasis on the strength of their orientation on such strategic issues as sustainable development, orientation towards innovation, as well as the level of maturity of their partnership with the client. The research method was carried out on a sample of 157 industrial enterprises in the food industry. The research process was conducted with the consideration of making these decisions dependent on the strength of companies’ commitment to several strategic issues: sustainable development, innovation orientation, and the maturity of their partnership with the customer. The results of the data analysis collected during the quantitative research show a strong correlation between the level of openness of the organization of the IR 4.0 era to RES and (a) orientation towards sustainable development, (b) orientation towards intelligence, and (c) maturity of strategic partnering with customers.

Concerns about the water–energy–food (WEF) nexus have motivated many discussions regarding new approaches for managing water, energy and food resources. Despite the progress in recent years, there remain many challenges in scientific research on the WEF nexus, while implementation as a management tool is just beginning. The scientific challenges are primarily related to data, information and knowledge gaps in our understanding of the WEF inter-linkages. Our ability to untangle the WEF nexus is also limited by the lack of systematic tools that could address all the trade-offs involved in the nexus. Future research needs to strengthen the pool of information. It is also important to develop integrated software platforms and tools for systematic analysis of the WEF nexus. The experience made in integrated water resources management in the hydrological community, especially in the frame of Panta Rhei, is particularly well suited to take a lead in these advances.

In southern Africa, the connections between climate and the water–energy–food nexus are strong. Physical and socioeconomic exposure to climate is high in many areas and in crucial economic sectors. Spatial interdependence is also high, driven, for example, by the regional extent of many climate anomalies and river basins and aquifers that span national boundaries. There is now strong evidence of the effects of individual climate anomalies, but associations between national rainfall and gross domestic product and crop production remain relatively weak. The majority of climate models project decreases in annual precipitation for southern Africa, typically by as much as 20% by the 2080s. Impact models suggest these changes would propagate into reduced water availability and crop yields. Recognition of spatial and sectoral interdependencies should inform policies, institutions and investments for enhancing water, energy and food security. Three key political and economic instruments could be strengthened for this purpose: the Southern African Development Community, the Southern African Power Pool and trade of agricultural products amounting to significant transfers of embedded water.

In order to address sustainability challenges, we posit that knowledge generation needs to move rapidly from a disciplinary linear ‘tree’ model to an interdisciplinary ‘web’ model. We show how such a shift is useful by looking at case studies in the context of water management.
