WaCClim Case Study // Water-Energy-Climate Nexus in Peru

Peru is particularly vulnerable to the impacts of climate change. A low-lying coastal area, with vast arid and semi-arid lands, much of Peru is liable to floods, droughts and desertification. 72% of the total number of national emergencies are due to hydro-meteorological threats.

Already struggling to secure a reliable supply to meet user’s demand, more frequent and severe natural disasters pose an increasing burden on water utilities in Peru. Huge differences in altitudes require enormous amounts of energy to distribute the water and lead to high energy costs.

Huge differences in altitudes require enormous amounts of energy to distribute the water and lead to high energy costs.

Droughts, intense rainfall or mudslides also affect drinking water and wastewater services, impacting the availability and quality of water, or damaging the utilities’ infrastructure. At the same time, providing drinking water to the population and treating wastewater are energy-intensive processes, and thus forming a significant part of a utility’s overall costs.

WaCCliM in Peru

The WaCCliM project in Peru cooperates with the General Directorate for Environmental Affairs under the Ministry of Housing, Construction and Sanitation, which is responsible for environmental policy in the water and sanitation sector including both mitigation and adaptation to climate change.

WaCCliM pilot utility of Cusco, SEDACUSCO, is already pioneering the way towards sustainable, low-carbon, urban water management.

About WaCClim

The water sector is increasingly being impacted by climate change. It also contributes more than 5 percent of global carbon emissions from its energy consumption, direct emissions of greenhouse gases such as methane and nitrous oxide from wastewater systems, and water heating from end users. Water loss in distribution networks and higher than necessary energy consumption are contributing factors.

WaCCliM (the Water and Wastewater Companies for Climate Change) is working with pilot water utilities in four countries, developing a road map to guide them towards energy and carbon neutrality.

Project // Improving Security and Climate Resilience in a fragile Context through the Water-Energy and Food Security Nexus (Frexus)

The Frexus project fosters cross-sectoral and integrated approaches in resource management, within local communities in Mali, Niger and Chad that are faced with the consequences of resource scarcity and climate change. The vicious cycle of resource scarcity, competition, conflict and instability currently challenging many communities, can be turned into a virtuous cycle of resilience, sustainable resources management, cooperation and security. Frexus (Nexus in Fragile contexts) aims at providing...

Pocket Flyer // Water, Energy and Food for All A Nexus Approach

The 2017 BMZ Water Strategy, with its six intersectoral strategies, is a binding basis for German Development Cooperation and integrates cross-sectoral thinking for economically sustainable, integrated and climatefriendly development. The Water, Agriculture and Energy Nexus is one of six intersectoral strategies, highlighting the need to achieve water, energy and food security for well-being.

Publication // What-If: An Open-Source Decision Support Tool for Water Infrastructure Investment Planning within the Water–Energy–Food–Climate Nexus

By Raphaël Payet-Burin, Mikkel Kromann, Silvio Pereira-Cardenal, Kenneth Marc Strzepek and Peter Bauer-Gottwein. This paper presents a new open-source hydro-economic optimization model, incorporating in a holistic framework, representations of the water, agriculture, and power systems. The model represents the joint development of Nexus related infrastructure and policies and evaluates their economic impact, as well as the risks linked to uncertainties in future climate and socio-economic...
