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

Located in one of the regions most vulnerable to the impact of global warming, Thailand has established policies, action plans and climate change mitigation and adaptation strategies over the last several years. In the Paris Agreement, Thailand has ambitiously committed to reduce its greenhouse gas emissions by 20% compared to projected business-as-usual (BAU) level compared to 2005 levels, with the option to increase its contribution to greenhouse gas reduction up to 25% by 2030.

Water pollution is a major environmental concern in Thailand. One of the main reasons is the unmanaged discharge of untreated domestic wastewater directly into water bodies resulting in the deterioration of water sources and significant GHG emissions. A growing population along with urbanization, industrial and agricultural expansion lead to an increased demand for water and wastewater services. At the same time climate change resulting in more frequent floods and droughts exacerbate the management of urban water services.

WaCCliM in Thailand

Recognising the importance of climate change mitigation in the wastewater sector beyond the municipal level, the WaCCliM project is working with the Ministry of Natural Resources and Environment (MNRE) and the Wastewater Management Authority (WMA) to improve the carbon balance of the pilot utility of Chiang Mai.

Three follower utilities in Hat Yai, Sansuk and Krabi municipalities, have started their journey towards climate mitigation in 2017.

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.

Peace and conflict

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...

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...
