Ensuring resilient food systems and sustainable healthy diets for all requires much higher water use, however, water resources are finite, geographically dispersed, volatile under climate change, and required for other vital functions including ecosystems and the services they provide. Good governance for resilient water resources is a necessary precursor to deciding on solutions, sourcing finance, and delivering infrastructure. Six attributes that together provide a foundation for good governance to reduce future water risks to food systems are proposed. These attributes dovetail in their dual focus on incorporating adaptive learning and new knowledge, and adopting the types of governance systems required for water resilient food systems. The attributes are also founded in the need to greater recognise the role natural, healthy ecosystems play in food systems. The attributes are listed below and are grounded in scientific evidence and the diverse collective experience and expertise of stakeholders working across the science-policy interface: Adopting interconnected systems thinking that embraces the complexity of how we produce, distribute, and add value to food including harnessing the experience and expertise of stakeholders s; adopting multi-level inclusive governance and supporting inclusive participation; enabling continual innovation, new knowledge and learning, and information dissemination; incorporating diversity and redundancy for resilience to shocks; ensuring system preparedness to shocks; and planning for the long term. This will require food and water systems to pro-actively work together toward a socially and environmentally just space that considers the water and food needs of people, the ecosystems that underpin our food systems, and broader energy and equity concerns.

Bassel Daher | Bassel Daher | Bassel Daher | Silva Hamie | Konstantinos Pappas | Konstantinos Pappas | Julie Roth
Lebanon faces a mix of underlying political and economic challenges, shocks, and triggering events that threaten the sustainability and resilience of its interconnected resource systems. The complex nature of these pressures begs for a systems approach to better understand the existing interconnections and to support the co-creation of cross-sectoral solutions to address them. This article specifically aims to: 1) conduct a scoping review of the existing literature and current events to identify interconnections between water-, energy-, and food-related challenges as they relate to the underlying conditions and triggering events at play in the context of Lebanon; 2) highlight ways in which the Water-Energy-Food (WEF) Nexus is a useful lens through which to understand and act upon issues at different scales; and 3) identify emergent themes including decentralization and systems thinking and their roles as catalysts toward more resilient resource systems. The examination concludes with two main recommendations: first, to create platforms and opportunities for interactive resource planning and decision making to facilitate systems-thinking for top-down WEF management; and second, to empower decentralized initiatives at the local level to build resilient, bottom-up solutions to WEF challenges.

Holowinski, Piotr | Dawidowicz, Andrzej L. | Typek, Rafal
Chlorogenic acid (CQA), the ester of caffeic acid with quinic acid, has been one of the most studied polyphenols due to its potential biological activity and usefulness in pharmaceutical treatment. We found that in an aqueous solution of each chlorogenic acid isomer, 3-, 4- and 5-CQA, its two complexes with water are formed. In the RP chromatographic system, these CQA-water derivatives differ in retention data from that of their precursors and do not decompose, which indicates their considerable stability. The formation of CQA-water complexes has not been reported yet. Comprehensive NMR research of CQA-water derivatives complexes shows that their significant stability results from the formation of hydrogen bonds between water and CQA isomer – e.g., between water and OH3, OH4 and ester groups of CQA molecule in the case of 5-CQA-water derivative. The existence of CQA-water derivatives in CQA containing food products was in the paper shown. It should be noted that the stable CQA-water complexes may exhibit a different biological activity than CQA. This issue requires separate biomedical research.

Water, energy and food are three essential resources for the socio-economic system, and they are interlinked. The coordination of their internal relations is worth studying. We conduct a coordination evaluation method to assess the water-energy-food nexus (WEF Nexus) in China’s provinces. By combining the coupling model and the coupling coordination model, we measure the comprehensive evaluation index and coupling coordination degree of China’s 30 provinces from 2005 to 2017. First, the results show the provincial comprehensive evaluation index had a slow upward trend. The comprehensive evaluation index of the southern region was higher than that of the north, and the eastern was higher than the west. Second, the coordination degree of WEF Nexus in China’s 30 provinces has reached high level in the horizontal coupling stage, and the overall degree of coupling coordination was on the rise. In 2017, the WEF Nexus coupling coordination degree of most provinces reached 0.700 or more, which was intermediate-coordinated. In the six years, the 30 provinces have experienced five types of coupling coordination degree: near coordinated, barely coordinated, primary coordinated, intermediate-coordinated, and well-coordinated.

Quantifying and analysing water trade-offs in the water-energy-food nexus: The case of Ghana Полный текст
2022

Water, Energy and Food (WEF) are inextricably linked, and the Water-Energy-Food nexus (WEF nexus) provides a comprehensive framework for addressing the complex and intricate interconnections in the development of these invaluable resources. Quantifying the interconnections among energy, water, and food sectors is a preliminary step to integrated WEF systems modelling, which will further contribute to robust WEF security management. However, the use of the WEF nexus concepts and approaches to systematically evaluate WEF interlinkages and support the development of socially and politically relevant resource policies in Ghana has been limited. This study sets the pace in the development of WEF nexus research in Ghana to facilitate policy and decision-making in the WEF sectors in the country. The study aimed at quantifying the existing water trade-offs in the WEF nexus and also modelling the trade-offs, considering basic development scenarios. The water intensities of food production and energy generation in Ghana were found to be 990 m3/tonne and 2.05 m3/kWh, respectively. Scenario analysis was done to project future annual water requirements for food production, energy generation as well as socio-domestic WEF demands based on two possible development scenarios. The analysis predicts that with business as usual, the annual water requirements for food production and energy generation as well as domestic sustenance in Ghana would increase by 34% in 2030. However, technological advancements and innovation in the energy and food sectors could reduce annual water requirements by over 26% even when 100% access to electricity is achieved nationwide.

Water rights trading is an important way to solve the problem of water shortage by market mechanism. The allocation of water rights among ecological water, energy water, and grain planting water are the basis of the regional water rights trade. In this paper, the concept of coordinated development of water&ndash:ecology&ndash:energy&ndash:food is proposed. We build a water rights allocation model with fairness, efficiency, and coordinated development as the goal, to achieve water security for various industries. Taking Yinchuan city as an example, the results showed that compared with the current water rights the water rights of life increased by 1.07%, the water rights of ecology increased by 1.85%, the water rights of energy industry decreased by 1.09%, the water rights of food planting decreased by 3.27%, the water rights of other agriculture increased by 0.83%, and the water rights of the general industry increased by 0.65%. After the allocation of water rights, the cooperativity of water&ndash:ecology&ndash:energy&ndash:food increased by 7.56%, and the total value of water resources in various industries increased by 2.31 ×: 108 CNY. A new water rights allocation model is developed in this paper, which can provide a reference for the allocation of water rights among regional industries.

GARCIA HERRERO Laura | GIBIN Davide | DAMIANI Mattia | SANYE MENGUAL Esther | SALA Serenella
Food consumption is responsible for most global water consumption and associated environmental consequences. Therefore, quantifying and monitoring the water footprint (WF) of food consumption patterns is relevant to support policymaking toward sustainable diets. Although multiple WF approaches are available, such as Water Footprint Assessment (WFA) and the model AWARE (Available Water Remaining) for supply chains analysis, the latest is considered the reference after following an international consultation process. This research aims to develop a comparative methodological approach between the volumetric blue water footprint assessment (WFA), a pressure method, and the scarcity-weighted WF AWARE model as an impact method to evaluate the WF of EU27 food consumption. Due to limited blue WFA data availability, two scopes were considered: an “aligned scope” (cradle to farm gate) comparing both methods and a “full supply chain scope” (cradle to grave) only possible with AWARE. In the aligned scope, almonds and cashew have the largest pressure and impact in both methods (per kg of product). EU food consumption has a WF pressure under an “aligned scope” of ≈54 m3/capita/year and an impact of ≈3525 m3 eq/capita/year. When considering the "full supply chain", WF impact due to EU food consumption increases by 30% (compared with the "aligned scope"). Integration of WFA data within the LCA inventory could be explored when WFA data also covers indirect WF of background processes and other supply chain stages. | JRC.D.3 - Land Resources and Supply Chain Assessments
