Abstract
Land, water, and energy resources are coming under unprecedented pressure owing to growing populations, urbanization, industrialization, and changing lifestyles, food habits, and climate. Generally, sectoral approaches are taken to address these challenges that overlook the close linkages between the water, energy and food sectors and resultant cross-sectoral implications. The result is an uncoordinated and unsustainable use of resources that increasingly threatens water, energy, and food securities in many parts of the world. To enhance sustainability in resource use, the use of water-energy-food nexus (WEF) approach has been advocated in recent years. Despite its conceptual appeals, the practical application of this approach in government planning and decision making has remained limited in part due to lack of an appropriate framework to operationalize the concept as a planning and decision-making tool. This paper suggests a framework for operationalizing the nexus concept in planning and decision-making, using South Asia as an example. The framework outlines four steps to evaluate and prioritize nexus issues to improve cross-sectoral planning and coordination using three broad criteria to assess the impact of actions in one sector on another: synergies (co-benefits), trade-offs (externalities), and neutrality. A cross-sectoral coordination body provides the institutional mechanism for ensuring coordination of policy and action. The four steps are: (a) harmonizing policy goals, (b) identifying interactions and critical connections between these sectors in an integrated manner, (c) assessing compatibility of nexus objectives and policy instruments, and (d) screening programs, projects, and investments against nexus goals. The framework is expected to help governments in coordinating the actions of diverse actors across the water, energy and food sectors and designing policies and programs that address trade-offs, while increasing production sustainably, conserving natural resources, and enhancing -water-energy-food nexus outcomes.
Highlights
The combination of increasing population, urbanization, industrialization, changing lifestyles, and consumption patterns is putting pressure on land, water, and energy resources (FAO, 2011; Rasul, 2014; Albrecht et al, 2018; Markantonis et al, 2019; Katz et al, 2020; Liu et al, 2020)
At present, around a billion people do not have access to electricity, and global energy demand is expected to rise by 25% by 2040 (International Energy Agency, 2019) and access to affordable, reliable and modern energy services envisioned in SDG7 will be at risk
How can we move from a sectoral approach to a more integrated approach and develop cross-sectoral strategies? In this paper, we attempt to develop a framework that can provide a basis for developing a common ground for strengthening cross-sectoral coordination in planning and prioritizing activities and for resource allocation and investment, using South Asia as an example
Summary
The combination of increasing population, urbanization, industrialization, changing lifestyles, and consumption patterns is putting pressure on land, water, and energy resources (FAO, 2011; Rasul, 2014; Albrecht et al, 2018; Markantonis et al, 2019; Katz et al, 2020; Liu et al, 2020). While the WEF nexus is becoming increasingly important, the lack of an appropriate framework that can integrate the water, energy and food sectors has been a key challenge in adopting the WEF nexus approach in policy planning and implementation.
