Integrated Management Approaches vs. Nexus Approaches // Learning from Integrated Management Approaches to Implement the Nexus

By Mario Roidt and Tamara Avellán. This paper assesses the intended goals and features of three Integrated Management Approaches: Integrated Natural Resources Management (INRM), Integrated Water Resources Management (IWRM) and Integrated Solid Waste Management (ISWM) as well as the two Nexus Approaches Water-Energy-Food (WEF) Nexus and Water-Soil-Waste (WSW) Nexus. It further looks at how target systems and their integration are viewed within each of the Integrated Management Approaches. From this the authors assess commonalities and some lessons-learned for the Nexus.

In the 1990s, the emergence of Integrated Management Approaches to water, land and waste established a widely accepted understanding on integration of environmental systems. Nexus Approaches try to often build on these. This paper assesses i) the intended goals and features of three Integrated Management Approaches (Integrated Natural Resources Management - INRM, Integrated Water Resources Management - IWRM and Integrated Solid Waste Management ISWM) and two Nexus Approaches (Water-Energy-Food (WEF) Nexus and Water-Soil-Waste (WSW) Nexus), and ii) how target systems and their integration are viewed in each of the Integrated Management Approaches. From this we assess commonalities and some lessons-learned for the Nexus. The method is based on a systematic literature review and a document analysis. From 1652 articles 52 peer reviewed papers were analysed.

The results show that in terms of goals the Nexus Approaches are very similar to Integrated Management Approaches with the addition of clearly wanting to address governance and policy aspects e.g. in the WEF Nexus. Nexus Approaches try to move away from a single-resource centric view (e.g. WSW Nexus) and intend to go beyond resources towards sectors (e.g. WEF Nexus).

It cannot be confirmed, that integration is clearly addressed in the analysed Integrated Management Approaches and what integration means is hardly defined. To provide some clarity for Nexus Approaches the authors propose a concept to describe integration by using “categories of integration” and the term “aspect” which includes systems, sub systems and other aspects alike.

Publication // A 40-year review of food–energy–water nexus literature and its application to the urban scale

By Newell, J. P., Goldstein, B., & Foster, A. (2019). What research exists to date on the FEW nexus? How have scholars conceptualized these interactions at the urban scale? What are some promising approaches? Where are the research gaps? To answer these questions, this paper conducts a quantitative review of the academic literature on the FEW nexus (1399 publications) over more than four decades (1973–2017), followed by in-depth analysis of the most influential papers using an evaluation matrix...

Policy Brief // Introducing Societal Metabolism Analysis via ‘MuSIASEM'

By Kerry A. Waylen, Kirsty L. Blackstock, Keith B. Matthews, Mario Giampietro. This paper introduces the Societal Metabolism Analysis, which is at the heart of the MAGIC project. It offers a way to characterise patterns of consumption and production associated with the metabolic patterns of different systems, thus enabling analysts to look across sectors and scales. It was developed by "MAGIC Nexus", a project by the European Union's Horizon2020 research and innovation program.
