This learning module shows how gender equity and social inclusion (GESI) considerations can be identified and integrated in programmes and initiatives in the Water-Energy-Food Environment (WEFE) Nexus. Intentionally focusing on gender and social inclusion in designing, implementing and monitoring Water-Energy-Food Environment initiatives is critical to ensure that these initiatives benefit and do not harm women and other marginalised groups and communities. At the end of this module, learners will be able to: (1) Explain the importance of gender equity and social inclusion for achieving sustainable development outcomes in the WEFE Nexus, (2) Describe common gender and social inclusion challenges and issues that WEFE projects face, (3) Describe the main steps for better addressing gender and social inclusion considerations. This module is intended for a broad audience that is working on, or interested in, cross-sectoral issues around sustainable use of water, energy, food and ecosystems, including decision-makers in public and private sectors as well as from civil society, practitioners and project implementers, graduate students and researchers, and donors

Aside from the many services that soil provides, it also stores water and makes it available to crops, which is critical for food security. However, the necessity of further studies for overcoming the existing gap in relation to the role of soil in the water, energy, and food nexus system has been preoccupying the experts and specialists around the world for some time. In this sense, the balance between many key ecosystem components based on the Soil, water, energy, and food (SWEF) nexus framework is one of the key characteristics of holistic and accommodative watershed management systems. To the best of our knowledge, the watershed scale is used as a planning unit for the first time in the current study to construct a conceptual model for adaptive management of optimum land-use/cover allocation using SWEF. The method was then used for the Shazand Watershed, Iran. Numerous metrics, such as soil erosion, soil organic carbon (SOC), water and energy use, mass efficiency, and economic efficiency, were investigated. Finally, a compound indicator was used to generate the SWEF nexus index (SWEFNI) for various land-uses/crops for the node year 2014. SWFENI ranged from 0.19 (worst) for rangeland to 0.78 (best) for almond plantations, according to the findings. The study's present approach may be tested worldwide.

This research paper addresses the need for an adaptable theoretical framework in the context of sustainable land governance for Water–Energy–Food (WEF) systems, bridging the gap between international guidelines and contextual realities. The novel framework is useful to effectively tackle the intricate challenges of rural and peri-urban revitalisation in the Global South by providing a holistic approach that considers the multi-dimensional interactions of land with water, energy, and food systems. The proposed framework encompasses three main objectives: (1) a top-down approach involving policy review and legal framework analysis to contextualise and inform the decision-making process; (2) a bottom-up approach based on case studies, enabling ground-level insights, stakeholder identification, and participatory mapping to empower rural and peri-urban communities; (3) a geospatial approach utilizing GIS and spatial analysis to study the implications of land within WEF systems. Drawing on mixed methods, including a literature review, a policy review, interviews, surveys, focus group discussions, and participatory action research grounded on case studies, this research emphasises the need to integrate both top-down and bottom-up approaches for comprehensive sustainable land governance. Over the course of 2018 to 2023, 22 master’s theses were supervised, each addressing the framework’s research objectives in 14 countries in Africa, Asia, the Middle East, and Latin America. Sixteen capacity building workshops in 11 countries engaged 851 participants, fostering knowledge exchange; 6 participatory action research (PAR) projects involved the installation of projects to advance food sovereignty in small communities in the Global South, following needs assessments. We showcase in this paper the PAR successfully implemented in Gitaraga, Rwanda, to validate the practical application of the proposed framework. The methodology has been useful for determining transversality, sustainability, inclusivity, adaptability, evidence-based decision-making, and policy integration as the core principles of sustainable land governance for WEF systems. The research contributes valuable insights to inform future interventions and policies that promote rural and peri-urban revitalization while addressing the ever-evolving challenges of WEF systems in the Global South.

While water-energy-food (WEF) Nexus is one of the most important, and widely investigated, environmental topics of our time, previous stock taking efforts possess notable limitations, namely (i) their focus is restricted to research articles, and (ii) there is less focus on nexus permutations that begin with energy and food. This paper assembled more than 900 documents and systematically categorized them according to more than 10 key parameters (e.g. scale, methods, limitations), to characterize approaches, achieved outcomes and presence of variables likely to support on-the-ground change. Our results reveal that WEF Nexus activities are often driven by the water sector, undertaken at global and national scale and authored by experts from diverse backgrounds. Among the utilized methods, modelling and review (i.e. systematic) are the most common. While climate change and governance are routinely considered in WEF Nexus documents, gender, stakeholders and capacity are not. These findings highlight areas for improvement in the design of WEF Nexus initiatives.

For our empirical research, the 2012 implementation of China's National Agricultural Water-Saving Outline serves as a quasi-experiment. In addition, one of the main regions in China for grain production is the Yellow River Basin. Based on this, we utilize a Difference-in-Difference (DID) empirical technique to assess the impact of the agricultural water-saving policy on food security using data from prefectures in China's Yellow River Basin from 2000 to 2020. According to the estimated results, grain production has greatly increased as a result of the agricultural water-saving policy. This conclusion still holds when other water-related policies are considered. The agricultural water-saving policy may enhance other input factors in grain production by assuring water demand, which is one possible mechanism of the influence. The empirical results show that the policy indeed increases the water productivity in agricultural production, which will ensure the effective water utilization in agricultural production, and the grain sown area, which is the most important production factor in agriculture. In heterogeneity analysis, the impact of the policy on food security is the largest in the lower reach, followed by the middle reach and the smallest in the upper reach in the Yellow River Basin. HIGHLIGHTS A Difference-in-Difference (DID) technique is employed to estimate the impact of the agricultural water-saving policy on grain yield in China.; The agricultural water-saving policy increases grain yield, thus improving food security in China.; The possible reason for the increase in grain yield is the increased agricultural water productivity as well as the grain sown area in China.;

In today’s intrinsically connected world, the Water–Food–Energy–Climate Nexus (WFEC Nexus) concept provides a starting point for informed and transparent decision-making based on the trade-offs and synergies between different sectors, including aquatic ecosystems, food security, energy production, and climate neutrality. The WFEC Nexus approach is particularly applicable in regions requiring transboundary water management, such as Central Asia. Unfortunately, this region with unevenly distributed water resources—consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan—is characterized by data scarcity, which limits informed decision-making. However, open-source geodata is becoming increasingly available. This paper aims to fill Central Asia’s WFEC Nexus data gap by providing an overview of key data. We collected geodata through an integrated survey of stakeholders and researchers, stakeholder consultation, and literature screening. Sixty unique datasets were identified, belonging to one of six thematic categories: (1) climate, (2) hydrology, (3) geography and topography, (4) geomorphology, (5) ecology, and (6) anthropogenic uses. For each dataset, a succinct description, including a link to the online source, is provided. We also provide possible applications of using the presented datasets, demonstrating how they can assist in conducting various studies linked to the WFEC Nexus in Central Asia and worldwide.

Despite evidence of women’s roles and expertise in the management of water, energy, food, and the environment (WEFE), the WEFE literature is almost silent on gender issues. In the context of climate change, achieving more inclusive management of natural resources is vital; yet women continue to be underrepresented as professionals in WEFE sectors, and largely absent in leadership positions. Using Nepal as a case study, this paper explores the enduring barriers to their exclusion, and entry points for greater equity among professionals in these sectors. To do so, we draw on key informant interviews with 34 male and 31 women professionals from government, civil society, non-governmental organizations and consultants, as well as a roundtable discussion with 20 women professionals specifically focused on gender barriers in these sectors in Nepal. Drawing on Gaventa (2006)’s power cube, this paper examines how power dynamics within and between the public and the private spheres create a web of barriers that conflate to sideline women professionals. While women have reached the “closed space” as defined by Gaventa (i.e., are recruited to professional positions in WEFE sectors), different sources of “hidden” and “invisible” power at play in the public and private spheres continue to limit their participation, influence and decision-making. We argue that the continued marginalization of women professionals calls for a focus on understanding the power and intersectionality dynamics that sustain exclusion. This focus is critical for the development of strategies to increase the voice and leadership of women professionals in WEFE decision-making.

Water is central for a variety of livelihoods, development, economic growth, and food production. It is also very important in the large deltas of South and Southeast Asia. Yet, water is turning into a scare resource and global climate change is making its availability more unpredictable. Commercial interests and infrastructure development are also competing for water resources, sometimes at the expense of local smallholders. This report, which is a desk study combined with stakeholder interviews, aims to map out the issues and the previously unknown challenges to efficient water and land management for poverty alleviation and food security. It also serves as a basis for an empirical case study on the same topic. The report illuminates the political economy of land-water resources in the floodplains around the Tonle Sap Lake which constitutes the upper part of the Mekong River Delta and shares seasonal fluctuations and livelihood patterns. The report identifies key challenges for land-water integrity and multi-functionality in food security, nutrition and income impacts for different local producers. The versatile delta landscape and its livelihoods are a complex ecosystem; the driving factors include seasonal water flow variations, the construction of upper Mekong dams, climate change, and the minimal regulations of local resource governance. This evidently makes the governance challenge both immense and urgent. This report maps out opportunities from national to local levels for promoting more systematic, productive and inclusive land-water management. The roles of formal and informal actors within political spaces, their influence on policy and practice, and opportunities to influence these actors are of particular interest. In pursuing the above, the report applies a political economy approach, where the role of the state, its policies and resource allocation are in focus. This also includes the presence of politically and commercially vested interests and how civil society is involved in the general strife for food security and poverty alleviation. The political economy approach constitutes a holistic analysis of how a society is governed and who possesses and utilises which power in order to pursue their interests. At the core of the political economy approach is therefore the illumination of power (and powerlessness) through analysis of actors or a group of actors and their particular interests. The empirical realms in this report focus on contemporary resource management, its institutions and actors.

Forest resources are an important foundation for human survival and development, and their utilization and management are of great significance for sustainable development. Forests are important ecosystems that provide essential ecological services for human survival and development. Based on the Gaussian model, this article evaluates the grain and water resources in forest areas to explore the efficiency of forest resource utilization. By collecting and processing sample data from the forest areas of the Yangtze River Basin from October to December 2021, the food and water resources of the forest areas under different vegetation types and soil moisture content were obtained. The results indicate that the total amount of grain resources varies among different sample areas. The maximum weight is 6,000 kg and the minimum weight is 3,500 kg. The total amount of water resources varies among different sample areas, ranging from 600 to 2,000 m3. HIGHLIGHT As an essential part of the ecosystem, forest resources have an important impact on human survival and development.; Based on the Gaussian model, this article evaluates food and water resources in forest areas and discusses the efficiency of forest resource utilization.; This article collected and processed sample data from forest areas in the Yangtze River Basin to obtain food and water resources in forest areas with different vegetation types and soil moisture contents.
