Nexus in Central Asia // WEF Nexus part of the "International Decade for Action - Water for Sustainable Development" Resolution

On 20-22 June 2018, the International High-Level Conference on the International Decade for Action "Water for Sustainable Development 2018-2028" was held in Dushanbe, Tajikistan. The water-energy-food Nexus in the context of water resources management was highlighted in the resolution "International Decade for Action - Water for Sustainable Development, 2018–2028," adopted by the UN General Assembly. The WEF Nexus was one of the main themes of the conference.

The water, energy, food and environment (WEFE) Nexus approach aims to create synergies and trade-offs for different sectors in order to improve water, energy and food security without causing damage to ecosystems. The Nexus approach compels us to think more long-term, providing room for multi-sectoral dialogue and negotiation. It thereby contributes to more robust institutions and coherent policymaking.  

At the high-level conference in Dushanbe, the action panel was organized by FAO, IFAD and IWMI in collaboration with SIWI, UNECE/Water Convention and the Pacific Water Research Centre. Representatives of IWMI, the Ministry of Agriculture of the Republic of Kazakhstan, UNESCO, UNECE, CAREC, Paraguayo de Itaipu Binacional and Earth Forever exchanged opinions on the following questions: 

  1. What are the interdependencies across the water, energy, food and ecosystem sectors at national and transboundary levels? 
  2. What are the knowledge gaps? 
  3. What policies, governance structures and actions are needed and how can the Nexus be integrated into national policies?
  4. What are the technological innovations that address the Nexus?
  5. What is the role of the Nexus in the 2030 Agenda? 

WEFE sectors are strongly interlinked. Actions in one sector commonly affect the other sectors. Water is used for energy production. Conversely, energy is needed for extracting, transporting, distributing and treating water. The production of food requires water and energy and agriculture is by far the largest user of water, accounting for 70% of worldwide water withdrawals. The agri-food sector energy demand is approximately one-third of the world’s total final energy demand.

However, plans are often developed without the consideration of similar initiatives in other sectors. This way of planning and implementation leads to asymmetries and tensions, sometimes even contradictory policies. It also generates additional financial costs, such as when infrastructure fails to address multiple purposes. Furthermore, additional funds are required to cover costs related to social or environmental risk management. A major issue is that investment financing needs for water, agriculture and energy infrastructure are generally considered separately. 

Farkhod Abdurakhmonov, manager of CAREC’s Water Initiatives Support Program, noted CAREC’s activities in mainstreaming the WEF Nexus approach in Central Asia. These efforts are implemented with the support of the European Union and in partnership with the International Union for Conservation of Nature (IUCN). They are largely achieved by intensifying the engagement of stakeholders for the promotion of integrated solutions that embrace water, energy and food security to reach environmentally sustainable economic development in the region.

As a result of the international conference, the final declaration “Promoting Action and Policy Dialogue” was adopted. The declaration stresses the need to manage water resources from source to sea around the water, food, energy and environment Nexus in an integrated and sustainable manner. This includes the promotion of the concept of a circular economy and other relevant resource-efficient solutions. The declaration calls for the prioritisation of water diplomacy and transboundary cooperation in line with the applicable principles of international law by strengthening inter alia the means of information and data exchange and open and inclusive multi-level and intersectoral dialogue in order to foster mutually-beneficial solutions and institutional arrangements.

Modelling and Assessment

Holistic Water-Energy-Food Nexus for Guiding Water Resources Planning // Matagorda County, Texas Case

By Muhammed I. Kulat, Rabi H. Mohtar and Francisco Olivera. The authors developed a holistic framework to provide sustainable scenarios that include feasible infrastructure interventions. The framework focuses on water and associated links with other resources, includes a unique analytic tool for quantifying scenarios, and ultimately produces a sustainability analysis of each scenario. Optimal scenarios are offered that consider site-specific dynamic resource interlinkages. The WEF nexus model...

Pompage Solaire // Investigation de l’impact des installations de pompage solaire sur la consommation d’eau et la situation socio-économique d’un agriculteur dans 3 zones pilotes au Maroc

Cette étude vise à mieux comprendre comment la conversion au pompage solaire peut influencer la consommation d'eau et les conditions socio-économiques d'un agriculteur marocain par rapport aux autres systèmes de pompage d'eau. L'étude s'est appuyée sur une enquête menée auprès de 150 agriculteurs répartis sur les territoires suivants 3 zones distinctes : la zone de Marrakech, la zone de Midelt et la zone de Tata. L'étude a été réalisée par le projet GIZ Sustainable Energy for Food - Powering...

WEF Nexus Research // Engaging Stakeholders in Research to address Water–Energy–Food (WEF) Nexus Challenges

By A. Larkin, C. McLachlan, R. Falconer, I. Soutar, J. Suckling, L. Varga, I. Haltas, A. Druckman, D. Lumbroso, M. Scott, D. Gilmour, R. Ledbetter, S. McGrane, C. Mitchell, D. Yu. This paper reflects on recent progress in stakeholder engagement in nexus-related research. The authors outline four emerging themes within nexus research and consider the value of, and potential challenges for, transdisciplinary research in each. Specifically, the authors examine how transdisciplinary approaches are...
