Case Study Peru // Planning locally, impacting globally – How Water and Wastewater Utilities in Peru are Facing Climate Change

This case is part of a case study series, where the Water-Energy-Climate Nexus supports the transition towards a more sustainable and low-carbon urban management. How to ensure water and sanitation services delivery under a climate change context? The climate change mitigation and adaptation plans (PMACC; Planes de Mitigación y Adaptación al Cambio Climático) are tools to address this challenge. PMACC identify main carbon emissions sources and higher climate risks throughout the urban water cycle, along with water utilities’ opportunities to boost a positive change towards climate neutrality and adaptation. Following a standardised methodology and supported by web-based tools, the planning process becomes quicker and generates a report to informing decision-makers. This planning approach enabled some water utilities in Peru to start searching for practical carbon emissions reduction solutions, such as water utilities in Cusco and Ayacucho. The PMACC initiative was developed and implemented collaboratively between WaCCliM (responsible for mitigation) and PROAGUA II.

Publication // The Development of the Water-Energy-Food Nexus as a Framework for Achieving Resource Security: A Review

By Gareth B. Simpson and Graham P. W. Jewitt. This paper presents a study of the evolution of the water-energy-food (WEF) nexus since its rise to prominence in policy and development discourses in 2011. Drawing from an extensive review of published literature, the paper presents various interpretations of the concept while also considering the novelty of the WEF nexus.

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...
