Full textAbstract:
The connections between universal rights to water supply, energy security, and food supply stand out as a challenge that requires project evaluation models that can capture the complex dynamics and interdependencies of these resources. This study proposes the elaboration of a nexus evaluation model (NEM) for projects related to the water–energy–food nexus (WEFN) from the perspective of sustainability, Industry 4.0, and the Sustainable Development Goals (SDGs). The model considers the three dimensions of sustainability—economic, environmental, and social; the three structuring factors of Industry 4.0—physical, biological, and digital; and the 17 SDGs proposed by the United Nations. A Design Science Research (DSR) approach was adopted in which the design and development of the model, and demonstration and evaluation phases, were supported by a group of experts. The model was applied to three different projects focused on sustainable technological innovation in energy and agriculture, with the results presented in the RGB color scale represented numerically as a number from 0 to 255. The results demonstrated that, in the relationship between nexus and sustainability, the projects presented scores between 162 and 217 for the environmental dimension, between 158 and 202 for the economic dimension and between 170 and 212 for the social dimension. In the nexus and Industry 4.0 relationship, the projects obtained scores ranging from 9 to 94 in the biological factor, from 13 to 141 in the digital factor, and from 13 to 141 in the physical factor. In the nexus and SDG relationship, scores ranged from 214 to 244 for water, from 195 to 255 for energy, and from 30 to 255 for food. These results from the model were consistent with the reality of the projects being evaluated, demonstrating a greater alignment of the projects with the dimensions of sustainability and the SDGs than with the factors of Industry 4.0. The proposal of the model contributes to broaden the understanding of how projects related to the nexus can be evaluated considering multiple contemporary dimensions.

Full textAbstract:
The synergistic regulation of the water–energy–food nexus in irrigation districts is important for promoting the sustainable management of agricultural resources in irrigation districts. In this paper, a new integrated optimization–evaluation modelling framework for the water–energy–food nexus in agricultural irrigation areas is developed. It can measure the synergistic effects of economic, social and environmental multidimensional objectives on the sustainable management of agricultural resources in irrigation areas. The model couples an optimisation module and an evaluation module, combines a multiobjective nonlinear planning model with an opportunity-constrained planning model and uses an entropy-weighted TOPSIS assessment approach to sustainably assess the multidimensional indicators of the water–energy–food nexus in irrigation districts, with full consideration given to the effects of uncertainty in agricultural water and soil resources and social systems. The feasibility of the constructed model is verified through a study of the Jinxi irrigation district. The results show that compared to the actual area, the optimised surface water and groundwater availability increased by 23.5% and 22.7%; the optimised total area increased by 4%, whereas corn decreased by 40%, rice increased by 34.6% and soybean decreased by 33.8%; the energy consumption decreased by 17.6% and the total recycled resources amounted to 8.97 × 109 kg, with a combined net economic benefit of CNY 1.25 × 109 more than the actual current amount. The synergistic development of the water–energy–food nexus (WEFN) in the district is relatively harmonious, suggesting that the district should focus on developing agricultural mechanisation and balancing economic benefits with environmental and ecological protection; furthermore, the model constructed should provide decision-making support for the efficient use of agricultural resources in the irrigation district.

Machine learning for water-energy-food-ecosystems nexus policy 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). The WEF nexus interacts strongly with ecosystems, forming the wider WEFE nexus. Ecosystems provide the ‘base’ of the WEFE nexus, helping ensure the quantity, quality, timing, and accessibility of WEF resources, for example, by providing services including water purification, contributing freshwater provisioning, pollution reduction and control; maintaining healthy landscapes, contributing towards crop growth for food and energy crops; biodiversity providing pollinating insects for crop production and; forest and floodplain ecosystems provide biomass that as act as a global carbon sink and oxygen supply (Bell et al. 2016; Martinez- Hernandez et al. 2017).

Abstract. Sustainable management of the water–energy–food (WEF) nexus remains an urgent challenge, as interactions between WEF and human sensitivity and reservoir operation in the water system are typically neglected. This study proposes a new approach for modeling the WEF nexus by incorporating human sensitivity and reservoir operation into the system. The co-evolution behaviors of the nexus across water, energy, food, and society (WEFS) were simulated using the system dynamic model. Reservoir operation was simulated to determine the water supply for energy and food systems by the Interactive River–Aquifer Simulation water resources allocation model. Shortage rates for water, energy, and food resulting from the simulations were used to qualify their impacts on the WEFS nexus through environmental awareness in society. Human sensitivity indicated by environmental awareness can then adjust the co-evolution behaviors of the WEFS nexus through feedback loops. The proposed approach was applied to the mid–lower reaches of the Hanjiang River basin in China as a case study. Results indicate that environmental awareness shows the potential to capture human sensitivity to shortages from water, energy, and food systems. Parameters related to boundary conditions and critical values can dominate environmental awareness feedback to regulate socioeconomic expansion to maintain the integrated system from constant resource shortages. The annual average energy shortage rate thereby decreased from 17.16 % to 5.80 % by taking environmental awareness feedback, which contributes to the sustainability of the WEFS nexus. Rational water resources allocation can ensure water supply through reservoir operation. The annual average water shortage rate decreased from 15.89 % to 7.20 % as water resources allocation was considered. Threats from water shortage on the concordant development of the WEFS nexus are significantly alleviated, particularly for the area with a limited regulating capacity for the water project. Therefore, this study contributes to the understanding of interactions across the WEFS systems and helps in improving the efficiency of resource management.

Full textAbstract:
Water, energy and food (WEF) security are key indicators of sustainable development. Realization of sustainable development goals (SDGs) by countries is achieved through a water-energy-food-ecosystem nexus framework. Climate change is a threat to food, energy and water security in the Horn of Africa. The main aim of this review is to assess the status and prospects of WEF nexus as it relates to SDGs in the horn of Africa. The countries considered were Ethiopia, Eritrea, Somalia and Djibouti. The review indicated that the four countries have a challenge in achieving SDGs 2, 6 and 7. Djibouti had the highest (50.9) WEF index in the region followed by Ethiopia and Somalia at 47.5 and 36.8, respectively while Eritrea had the lowest WEF index of 35.8. The energy sub-index was the best performer in the region with an average index of 56 while water and food sub-indices were the worst at 36. Political instability, insecurity, inadequate infrastructure, weak institutional and legal framework are some of the challenges facing WEF and sustainable development in the region. Climate change adaptation measures should be incorporated into the water, energy, food and ecosystem (WEFE) nexus using an integrated approach. Modelling WEFE requires integration of models and should also focus on interactions among the sub-systems.

The objective of this study is to describe a target water–energy–food (WEF) nexus domain world including causal linkages and trade-off relationships between WEF resources and their stakeholders, and to develop a WEF nexus system map as an interdisciplinary tool used for understanding the subsequent complexity of WEF nexus systems. An ontology engineering method, which is a qualitative method, was applied for the replicability of the WEF nexus domain ontology and the map, because ontology engineering is a method of semantic web development for enhancing the compatibility of qualitative descriptions logically or objectively. The WEF nexus system map has three underlying concepts: (1) systems thinking, (2) holistic thinking, and (3) an integrated approach at an operational level, according to the hypothesis that the chains of changes in linkages between water, energy, and food resources holistically and systemically affect the WEF nexus system, including natural and social systems, both temporally and spatially. This study is significant because it allows us to (1) develop the WEF nexus domain ontology database, including defining the concepts and sub-concepts of trade-offs relating to WEF for the replicability of this study; (2) integrate the qualitative ontology method and quantitative network analysis method to identify key concepts serving as linkage hubs in the WEF nexus domain ontology; and (3) visualize human–nature interactions such as linkages between water, energy, and food resources and their stakeholders in social and natural systems. This paper also discusses future challenges in the application of the map for a science–policy–society interface.

Full textAbstract:
This paper aims to analyze the scientific evolution and research trends concerning the water–energy–food (WEF) nexus, as well as its development within scientific databases. To achieve this, a bibliometric analysis has been conducted using publications sourced from Scopus and Web of science databases. This study examined key aspects such as primary journals, prominent authors, affiliated institutions, countries of origin, subject areas, and notable keywords. Furthermore, there is a dedicated section that delves into research and innovation gaps within publications related to the WEF nexus. Results reveal that research on the WEF nexus has experienced exponential growth over the past decade, with the majority of publications emerging between 2017 and 2023. The United States leads in this field, with engineering and environmental science being the predominant research categories, with Spain and Italy being the prominent countries in Europe. The WEF nexus concept in the agriculture sector is notably underdeveloped, particularly in its ties with the Sustainable Development Goals and the science–policy–society interface. The study stresses the importance of integrating health considerations into the WEF Nexus to understand the interconnections and their implications on public health, thereby enriching the Nexus approach with a critical dimension of human well-being. This situation underscores the urgent need to create a nexus community that bridges science and practice, and to incorporate this specialized discipline into university curricula.

With the possibility of the Water-Energy-Food (WEF) Nexus since a long time back, overlooked interlinkages between WEF are getting the chance to be indisputable. Nonetheless, agriculture is responsible for quite a bit of fresh water over-use. Food production further effects the water and energy sectors through degradation of land, changes in overflow, disturbance of groundwater release, water quality, accessibility of water and land for different purposes. The responsibilities of this unparalleled issue include particular parts of the organization around the Nexus. While a couple of papers try to conceptualize the Nexus-Governance, this phenomenal report gives a rich combination of work for further WEF-Nexus ponders and integrative methodologies.

Full textAbstract:
Notwithstanding the dispersed nature of the water, energy and food (WEF) nexus scholarship in the African continent, its strategic importance to the African agenda has gained widespread attention in research and planning circles. In this regard, the bibliometric science mapping and content analysis of the WEF nexus scientific publication trends, the conceptual, intellectual and social structures, as well as the inherent paradigmatic shifts in the WEF nexus body of knowledge in the African continent have been undertaken, using the nexus body of literature accessed from the Web of Science and Scopus core collection databases. The review results confirmed that, whilst the WEF nexus scholarship has expanded since 2013, there is also evidence of growth in the conceptual, intellectual and social structures of the WEF nexus in the African continent. These shifts have resulted in the emergence of hot topics (subfields) including modelling and optimization, climate variability and change, environmental ecosystem services sustainability, and sustainable development and livelihoods. The review further determined that these structures have evolved along two main perspectives of WEF nexus research development, i.e., the interdisciplinary and transdisciplinary domains. In support of the interpretation of the visual analytics of the intellectual structure and changing patterns of the WEF nexus research, the shifts in positivist, interpretivist and pragmatic paradigmatic perspectives (these are underpinned by the ontology, epistemology, and methodology and methods) are considered when explaining WEF nexus research shifts: (a) From the unconnected silo paradigms that focus on water, energy and food (security concerns) to interconnected (and sometimes interdependent or nested) linkages or systems incorporating environmental, social-economic and political drivers (also viewed as subfields) in a bid to holistically support the Sustainable Development Goals (SDGs) across the African continent; and (b) in the evaluation of the WEF nexus scholarship based on novel analytical approaches. We contend that whilst the theories of science change underpin this apparent expansion, the macro-economic theory will find use in explaining how the WEF nexus research agenda is negotiated and the Integrative Environmental Governance (IEG) is the duly suited governance theory to bridge the inherent disconnect between WEF nexus output and governance processes uncovered in the literature. Overall, operational challenges and opportunities of the WEF nexus abound, transitioning the WEF nexus research to practice in Africa, motivating the need to take advantage of the scholar–practitioner research underpinnings, as contemplated in the transdisciplinary research approach, which is characterised by the dual quest for new knowledge and considerations of use. Yet, there is need for more coordinated and collaborative research to achieve impact and transition from WEF nexus thinking to WEF nexus practice.

Cette étude présente une méthodologie générique multi-acteurs et multi-niveaux pour la gestion des systèmes nexus eau-énergie-alimentation. Les systèmes nexus eau-énergie-alimentation sont des systèmes où l’eau, l’énergie et l’alimentation interagissent et présentent des synergies et des compromis à différentes échelles spatiales et temporelles. Leur gestion est menée par des décideurs provenant de secteurs divers, qui interviennent à des niveaux de décision variés. Ces systèmes sont complexes et le niveau opérationnel ne peut être négligé pour concevoir des stratégies de gestion adéquates.Ce travail présente la première méthodologie destinée aux systèmes nexus eau-énergie-alimentation, qui combine des simulations opérationnelles et intégrées de systèmes multi-agents avec des méthodes d’aide à la décision stratégique. Les simulations à échelles opérationnelles alimentent des outils d’aide à la décision stratégique. La méthodologie a été appliquée à des problèmes d'utilisation des terres à l’échelle de la parcelle agricole. Pour chaque territoire étudié, le nombre de combinaisons possibles d'allocations de stratégies d'utilisation des terres aux parcelles est égal au nombre de stratégies d'utilisation des terres considérées pour chaque parcelle, exponentiel le nombre de parcelles du territoire. Des méthodes d’aide à la décision multicritères basées sur des simulations Monte Carlo ont été conçues afin de pouvoir trouver des solutions de gestion pour des grands territoires (plus de 1000 parcelles) pour lesquels plus de deux stratégies d’utilisation des terres sont considérées sur chaque parcelle. Une méthode d'optimisation multi-objectif a été conçue pour produire des scénarios d'utilisation des terres optimisés à l’échelle du territoire.La méthodologie a été appliquée à un territoire agricole d'environ 800 km² et 15224 parcelles situé en aval du bassin versant de l’Aveyron en France. Le bassin versant subit du stress hydrique et se trouve dans l'une des régions les plus ensoleillées de France. La production d'énergie renouvelable sur des terres agricoles apparaît comme un moyen de répondre aux objectifs nationaux de production d'énergie renouvelable et de progresser vers des systèmes et des régions agricoles durables. L'installation d'unités de production d'énergie renouvelable sur des terres agricoles confrontées au stress hydrique est une parfaite illustration d'un système nexus eau-énergie-alimentation pour lequel une approche holistique est requise. Les fonctionnalités de la plateforme multi-agents MAELIA (modélisation des systèmes socio-agro-écologiques pour l'évaluation intégrée des paysages), développée par des chercheurs français pour simuler des systèmes agro-hydrologiques complexes, ont été étendues et MAELIA a été utilisée pour simuler la dynamique des systèmes nexus eau-énergie-alimentation au niveau opérationnel. Trois méthodes qui combinent la procédure d’analyse hiérarchique (méthode de prise de décision multicritères) avec des simulations Monte Carlo ont été conçues. La première se base sur des indicateurs à l’échelle de la parcelle pour émettre des décisions locales ; elle sélectionne des stratégies d'utilisation des terres qui optimisent des indicateurs au niveau de la parcelle. Les deux autres méthodes basent leurs prises de décisions sur des indicateurs régionaux. La première identifie le meilleur scénario régional d'utilisation des terres parmi un ensemble de scénarios connus et la deuxième explore l’espace combinatoire des allocations de stratégies d'utilisation des terres à l’échelle de la parcelle et sélectionne une combinaison qui optimise les critères au niveau régional. Une méthode d'optimisation multi-objectif basée sur la programmation linéaire en nombres entiers mixtes (MILP) et la programmation par objectifs a été développée avec le logiciel IBM ILOG CPLEX pour produire des scénarios optimisés à l’échelle régionale, qui allouent des stratégies d’utilisation des terres à l’échelle de la parcelleThis study presents a generic multi-actor multi-level methodology to optimize the management of water-energy-food nexus systems. Water-energy-food nexus systems are systems where water, energy and food resources interact and present synergies and trade-offs at varied spatial and temporal scales and whose management is impacted by cross sector decision-makers and stakeholders that take action at varied decision levels. Water-energy-food nexus systems are complex and dynamic systems for which the operational level cannot be overlooked to design adequate management strategies.The novelty of this methodology lies in it being the first one to combine spatial operational multi-agent based integrated simulations of complete water-energy-food nexus systems with strategic multi-criteria decision-making methods and multi-objective optimization. The framework simulates nexus systems at temporal and spatial operational scales to derive strategic spatial allocations of resources. The framework is used to allocate land-use alternatives to parcels for agricultural territories. The number of possible combinations of land-use allocations to parcels equals the number of possible parcel land-use allocations explored for each parcel exponential the number of parcels in the territory considered. Multi-criteria decision-making methods based on exploratory Monte Carlo simulations have been designed to provide decision support for large territories (more than 1000 parcels) for which more than two land-use allocation alternatives are compared for each parcel. A multi-objective optimization method has been designed to produce optimized regional level land-use scenarios. The multi-objective optimization method is limited computationally and can face convergence issues when the number of possible combinations of land-use allocations to parcel explodes.The methodology has been applied to an agricultural watershed of approximately 800 km2 and 15224 parcels situated downstream the French Aveyron River. The watershed experiences water stress and is located in one of France’s sunniest regions. Renewable energy production in agricultural land appears as a means to meet national renewable energy production targets and to move towards autonomous sustainable agricultural systems and regions. The installation of renewable energy generation units in agricultural land facing water stress is a perfect illustration of a complex water-energy-food system for which a holistic approach is required. MAELIA (modelling of socio-agro-ecological systems for landscape integrated assessment), a multi-agent based platform developed by French researches to simulate complex agro-hydrological systems, has been extended and used to simulate dynamics of water-energy-food nexus systems at operational level. Three strategic multi-criteria decision-making methods that combine Monte Carlo simulations with the Analytic Hierarchy Process method have been designed. The first one is local; it selects land-use alternatives that optimize multi-sector parcel level indicators. The other two are regional; decisions are based on regional indicators. The first regional decision-making method identifies the best uniform land-use regional scenario from those known and the second regional decision-making method explores the possible combinations of land-use allocations to parcels and selects the one that optimizes multi-sector criteria at regional level. A multi-objective optimization method that combines MILP (Mixed Integer Linear Programming) and goal programming has been implemented with IBM’s ILOG CPLEX optimization studio to find parcel level land-use allocations that optimize regional multi-sector criteria

Full textAbstract:
Controversy in transboundary rivers usually arises due to a lack of inclusive agreement and cooperation between the basin countries. Originating from Ethiopia, the Blue Nile River contributes most of the Nile River water making it vital for water, energy, and food security at downstream Sudan and Egypt. In 2011, the Ethiopian government announced the construction of the Grand Ethiopian Renaissance Dam (GERD) along the Blue Nile 40 km away from the Sudanese borders. The dam will be the biggest in Africa and seventh-largest in the world producing 6,000 Megawatts of electricity with a reservoir volume of 74 billion cubic meters. Great concerns were raised on the impact of this megaproject for downstream countries due to the expected changes in water quantity and quality. Different studies were published regarding the potential impacts of this dam on the Eastern Nile countries. However, these studies have usually focused on one aspect of the impact (e.g. hydropower, agricultural projects, water use) despite the connection that exists between these sectors. This research aims to investigate the impact the GERD operation will have on Sudan in terms of WEF security and sustainability. The study uses the WEF security nexus framework that addresses the interconnectedness between these sectors instead of treating them in silos. A sustainability assessment is also carried out to analyze the impact of the dam operation on the environmental, social and economic areas in Sudan. The study first looked into the current state of Sudan’s WEF security nexus and highlighted the vulnerabilities that exist within these sectors. Then an analysis of the GERD operation was carried out and the results showed that water regulation and sediment reduction will reflect positively on Sudan as it will enable for expansion in agricultural projects, increase hydropower production, and provide flood control. Some negative impacts, however, are to be expected especially during the impounding phase from water level reduction and change in river characteristic which will greatly affect the environment and society downstream. The safety of the dam was found to be the biggest threat to Sudan’s security, as the case of dam failure will have catastrophic consequences for the country. The study concluded that an increase in cooperation between the Eastern Nile countries will decrease the downstream negative impacts of the GERD and increase its overall benefits ultimately leading to sustainability, peace, and welfare for these countries. Sudan also needs to take measures in accommodating the new flowing conditions including reoperation of the Sudanese dams and mitigation strategies for the potential negative impacts.

Full textAbstract:
It is undeniable that activities and events within the water, energy, and food (WEF) security nexus are inextricably linked and their relationships numerous and substantial. Complexity increases when factors governing the daily lives of humanity namely social, technology advancement, environment, economic, and policies (STEEP) adds upon the difficulty in addressing the relationships. It is thus paramount to address the problems from a holistic and systematic approach to maximise benefits as well as to minimize the negative impacts upon one another. However, there exists little to zero means of measuring their performance, whether qualitatively or quantitatively, within the context of a nexus. Moreover, minimal understanding exists regarding the relationships between the WEF securities in Malaysia, an emerging economy rich in natural resources, which envisions to be a developed nation. This research sought to establish a measurement system for the WEF security nexus in Malaysia within the context of resource security wellbeing, sectoral balance, and sustainable development using a System Dynamics (SD) approach. This entailed an extensive literature review and qualitative interview with key stakeholders from the industrial sectors. The front end of the SD process is concerned with obtaining important and relevant information from literature and interviews, which are then used to construct causal loop diagrams (CLD). The back end of the SD is concerned with converting the CLDs into a stock and flow diagram (SFD), which provides a platform for quantitative simulation of different well-designed scenarios. Key findings from this research can be highlighted; these include: renewables are necessary for the long-term energy plan of Malaysia, nuclear power is necessary to keep electricity tariff low, water tariff of supply and services are severely low, increasing self-sufficiency level (SSL) of Malaysia’s staple food is important, under-utilised crops are efficient in meeting nutrient requirements, and cash crops imposed systemic stresses upon the water sector more than the energy sector. Consequently, recommendations for policy makers are suggested accordingly to achieve a reasonable proportion of RE penetration, providing education on nuclear benefits, centralising and streamlining water governance, socio-economic improvement of water economics, increase SSL of staple food, embark upon widespread adoption of local under-utilized crops, and controlling land use of non-food crops. The outcome of this research forms a vital and novel contribution to knowledge, when it is a pioneering work to address the WEF security nexus for Malaysia; especially in considering their securities for the country as a system rather than unaffected individual entities. This work will contribute towards spearheading the awareness and, hopefully, trigger further and more in-depth work in transdisciplinary resource and technology management. As a pioneering effort, this research has nonetheless provided the foundation and the fundamental understanding to an integrative and inclusive cross-sectoral national resource backbone - The WEF security nexus measurement system of Malaysia.

A fundamental change in societal values and economic structures is required to address increasing pressures on ecosystems and natural resources. Transition research has developed in the last decades to analyze the co-dynamics of technological, institutional, social and economic elements in the provision of key functions such as energy, water and food supply. This doctoral dissertation provides conceptual and methodological contributions to the pro-active governance of sustainability transitions. Three research gaps are identified that are addressed in this dissertation. First, a comprehensive conceptualization of learning in sustainability transitions is currently missing that comprises learning at multiple societal levels (ranging from individuals to policy-actors). Learning concepts are often not explicitly discussed in transition research even though learning is considered as fundamental for innovation processes, niche formation and development as well as breakthrough and diffusion of innovations. Second, methods for the analysis and design of transition governance processes are lacking that specify case-specific intervention points and roles of actors in the implementation of innovations. Third, participatory modeling approaches are only applied to a limited extent in transition research despite a high potential for supporting communication and learning.
The conceptualization of multi-level learning developed in this doctoral research conceptualizes learning at different societal levels as specific learning contexts ranging from individual and group contexts to organizational and policy contexts. The conceptual framework further differentiates between learning processes, intensity, objects, outcomes, subjects and factors, allowing for a more detailed analysis of learning within and across learning contexts. Thus, learning contexts can be linked by processes that involve actors from different learning contexts (e.g., community groups and policy-makers), as well as exchanges of physical aspects, institutions and knowledge (in the form of ‘learning factors’). This research has also provided a classification of model uses in transition research that supports a purposeful discussion of the opportunities of modeling and promising future research directions.
The methodology developed in this doctoral research aims at the analysis and design of transition governance processes by specifying the various opportunities to contribute to sustainability transitions through purposeful action at different societal levels, as well as related roles of stakeholders in implementing such processes of change. The methodology combines different streams of previous research: 1) a participatory modeling approach to identify problem perceptions, case-specific sustainability innovations as well as related implementation barriers, drivers and responsibilities; 2) a systematic review to identify supportive and impeding learning factors from the general literature that can complement case-specific factors; and 3) a method for the analysis and design of case-specific transition governance processes. Three case studies in Canada (topic: sustainable food systems), Cyprus (water-energy-food nexus) and Germany (sustainable heating supply) have been selected to test and iteratively develop the methodology described above.
The results for each case study reveal that there are learning objects (i.e., learning requirements) in all learning contexts, which underscores the importance of multi-level learning in sustainability transitions, ranging from the individual to the group, organizational and policy levels. Actors have various opportunities to actively facilitate societal transformations towards sustainable development either directly through actions at their particular societal levels (i.e., context-internal learning) or indirectly through actions that influence learning at other societal levels. In fact, most of the learning factors require cooperation across learning contexts during the implementation process. The comparing of learning factors across case studies underline the importance of several factor categories, such as ‘physical a ‘disturbance or crisis’, ‘information and knowledge’. Of the 206 factors identified by stakeholders, 40 factors are case-specific and not contained in the general, review-based factor list. This underscores the value of participatory research, as general, top-down analyses might have overlooked these case-specific factors.
The methodology presented in this dissertation allows for the identification and analysis of case-specific intervention points for sustainability transitions at multiple societal levels. The methodology furthermore permits the analysis of interplay between individual, group, organizational and policy actions, which is a first step towards their coordination. The focus on sustainability innovations links the broad topic of sustainability transitions to a set of opportunities for practical interventions and overcoming their implementation barriers. The methodology presented allows for the analysis and design of these interlinkages between learning contexts. While the methodology cannot provide any ‘silver bullets’ for inducing sustainability transitions, it is flexible enough to identify an appropriate abstraction level for analyzing and designing transition governance processes. The methodology developed in this doctoral research also provides several contributions for the development of participatory modeling methods in transition research. Thus, the participatory method supports an integrated analysis of barriers and drivers of sustainability innovations, and allows application in practice and education.
The concepts and methods developed in this research project allow for reflection on transition governance processes from a systemic viewpoint. Experiences in the case studies underline the applicability of the concepts and methods developed for the analysis of case-specific transition governance processes. Despite substantial differences in the geographic location, culture and topics addressed, all case studies include promising sustainability innovations and the engagement of multiple actors in their implementation. The diversity and multitude of initiatives in the case study regions provides an optimistic outlook on future opportunities for large-scale sustainability transitions.

Full textAbstract:
The water-energy-food (WEF) nexus is the subject of much research focusing on different aspects, a wide range of issues, and development of a variety of models and tools. This study takes a different approach by developing a holistic framework that concentrates on the spatial elements of continuity and change associated with WEF transition on national, regional, and international scale. The study also investigates the interconnected challenges that could affect these resources and the actions and polices that should be taken on different geographical scales to address these challenges. The results can help practitioners and policy makers gain a clearer understanding of the state of the knowledge when performing WEF nexus assessments at different geographical scales.

Full textAbstract:
The issue of energy self-sufficiency is currently crucial. The concept of energy selfsufficiency is closely related to the concept of energy security; yet, there are many definitions for the term energy security. The essence of all of them is for a country to secure enough energy resources to cover its needs. If a country can secure these resources on its own without depending on imports from other countries, one refers to energy self-sufficiency. Energy self-sufficiency can be achieved in a number of ways such as reducing energy demand, improving fuel efficiency, securing physical infrastructure networks, increasing storage capacity, or increasing the use of renewable energy sources. Fundamental forms of energy self-sufficiency are external self-sufficiency, internal selfsufficiency, and energy consumption; overall, energy self-sufficiency consists of four components: availability; affordability; energy and economic efficiency; and environmental stewardship. Low energy self-sufficiency has a significant economic and social impact, which is reflected in a country's balance of payments and employment, it can lead to economic crises and price instability. Lack of access to reliable and affordable energy can result in food insecurity; health problems; limited access to education, social and economic development. The linkages between energy, food self-sufficiency, and self-sufficiency of water resources are considered in terms of the so-called WEF Nexus (Water-Energy-Food Nexus) that focuses on the interconnectedness of water, energy and food systems to promote sustainable development and address global climate change. Based on the application of scientific methods in relation to the investigation of energy self-sufficiency (the �E� Matrix in the framework of the WEF Nexus) on the background of quantitative & qualitative sustainable development and CSR trends, the main aim of our paper is to assess energy self-sufficiency in the context of the WEF nexus as well as in the light of the United Nations 2030 Agenda Sustainable Development Goals (SDGs) in order to formulate opportunities arising from the European Union Recovery and Resilience Plans. When documenting quantitative & qualitative sustainable development trends in the context of the WEF Nexus, our paper addressed the United Nations 2030 Agenda (alias �SDG diplomacy�) as well as the NextGenerationEU Agenda (alias �Green Deal diplomacy�).

Full textAbstract:
Water is one of the basic necessities of life. However, water crises have become more frequent around the world as billions of people continue to suffer from a lack of access to clean water, sanitation and hygiene. Water is a limited resource that has been in growing demand � with the world's population increasing and water-intensive economic development continuing, infrastructure of many countries is not fit to meet accelerating demand. With climate change and its variability fluctuations in rainfall and extreme temperatures occur, causing shorter rain seasons and longer dry periods � making water and its availability more unpredictable. These changes have a serious impact on lives and livelihoods. Water is essential in all sectors for the production of food, energy, goods, and services. Over the past century, global water consumption has increased at more than twice the rate of population growth. Many water sources are drying up, more polluted, or both. The European Environment Agency (EEA) defines water stress as a situation where there is not enough water of sufficient quality to meet the needs of the people and of the environment. Lack of water is a relative term, the amount of water that is physically available changes as supply and demand change. Water scarcity intensifies when demand increases and/or when water supply is affected by declining quantity or quality. Water, energy and food security are key to sustainable long-term economic development and human well-being. The water, energy and food nexus focuses on decision-making in the complex linkages between systems that produce, supply and use goods and resources. The purpose of assessing such linkages is to identify untapped potential of synergies, such as in the case of water- and energy-related measures and the consequent impact of coordinated measures in contrast to uncoordinated measures. Based on the application of scientific methods in relation to the investigation of sustainability in water resources (the �W� Matrix in the framework of the Water- Energy-Food (WEF) Nexus) on the background of quantitative & qualitative sustainable development and CSR trends, the main aim of our paper is to assess sustainability in water resources in the context of the WEF nexus as well as in the light of the United Nations 2030 Agenda Sustainable Development Goals (SDGs) in order to formulate opportunities arising from the European Union Recovery and Resilience Plans. When documenting quantitative & qualitative sustainable development trends in the context of the WEF Nexus, our paper addressed the United Nations 2030 Agenda (alias �SDG diplomacy�) as well as the NextGenerationEU Agenda (alias �Green Deal diplomacy�).

Full textAbstract:
This paper examines the water–energy–food (WEF) nexus in a humanitarian context, with a specific focus on water, sanitation and hygiene (WASH). It highlights the complex and non-linear interactions that WASH has with other areas of the WEF nexus. In doing so, it blends the social dimensions (access, safety, consumption, and use) with the WEF resource dimensions (availability and resource sustainability), including a further emphasis on sanitation as a key, but often ignored, element of the WEF nexus. Drawing on the case of the Rohingya refugee camps in Bangladesh, we examine how household-level access to WASH shapes and is shaped by use, access, and availability of energy and food, and finally their effects on host–refugee interactions. We find that there are implicit and explicit links between WASH and WEF. Moreover, any small intervention in any of the WEF areas has positive knock-on effects on the other resources, especially in enhancing resource access and use. We conclude that bottom-up perspectives on these interlinkages with active participation from both host and refugee households are required to understand the implicit and explicit connections across WASH and the WEF nexus in humanitarian contexts. We also argue that sanitation is a key element of the WEF nexus and should not be ignored within the predominant resource-centric framing of the WEF.

This discussion paper contributes to the broader discourse on the nexus between Water, Energy and Food (WEF) in parts of Syria where Oxfam works. It explores the main causes behind the deterioration of the WEF sectors and the impact they have on households across Syria. The paper also focuses on aspects that directly impact and limit Oxfam's work inside Syria, in the delivery and implementation of Water, Sanitation and Hygiene; Livelihoods; Food Security and Protection interventions. Addressing the WEF Nexus in Syria is key in delivering more effective and sustainable interventions; and helping Syrians restore their lives.
