The research and dialogue activities are being conducted in eight secondary cities – two cities per country in the region. Cities are selected on the following criteria: clarity of climate related issues, urbanization processes (i.e. cities that are growing/urbanizing), links to regionalization, background of engagement and supporting data, political buy-in from local governments and leaders, replicability and transferability to other locations, and logistical and practical accessibility. This report provides reasons and data to support the selection of Battambang municipality of Battambang province as a case study site in Cambodia. It is premised on the existing scholarship and a field visit to and a consultation workshop with relevant stakeholders in the province by the research team. The sections to follow entail each of the criteria that corroborate the selection of the municipality. 1. Clarity of climate issues Location (Source: ADB’s Great Mekong Subregion (GMS) Corridor Towns Development Project (TA 7644- REG) Figure 1: Location of Battambang town inside Battambang province 4 Battambang is part of the greater natural landscape of the Cardamom region1. The natural habitats of this region form a complex network of interconnected landscapes and watersheds that provide important ecosystem services to the region (Killeen 2012). Sangkae River is one of the key sources of water for the foundation of city development in Battambang. It originates from the range of the Elephant and Cardamom Mountains at an elevation of about 1,391 meter sea level (msl) , flows from the southwest to North across Battambang Town and joins the Stung Mongkol Borey River at Bac Prea village about 40 kilometers downstream from Battambang Town, and the Stung Sreng River at another further 10 kilometers downstream. It then flows into the Tonle Sap Great Lake. The upper Stung Sangker River is the combination of two rivers, namely, the Stung Sangker itself and the Stung Chamlang Kuoy (Cambodia National Mekong Committee-CNMC 2012). At O Dambang, which is located about five kilometers
