Heat Island Effect in an Industrial Cluster - Identification, Mitigation and Adaptation

The Ib-Valley region of Odisha is a rapidly growing industrial hub with a range of large industries as well as coal mining. The study seeks to assess the heat island effect in this region, which could be attributable to anthropogenic activities. This briefing paper outlines the Heat Island mitigation and adaptation strategies based on the study conducted in this region. Thermal hotspots have been identified using approaches such as remote sensing based Land Surface Temperature (LST) modelling and field survey based ambient temperature and humidity monitoring. It provides a comprehensive strategy for mitigation and adaptation of the heat island effect in the areas of coal mining, industries, agriculture, transport, and urban planning. The sectoral contribution of different sources and sinks to heat islands has been analysed to determine where actions can be targeted. Sector specific measures to reduce the heat island effect over the Ib-valley region in Jharsuguda have been recommended on the basis of analysis of the contribution of each measure to the reduction in heat release. An indicative potential of the impact of each measure along with the cost of implementation were estimated, wherever sufficient data was available. However, the execution of these plans requires investment, commitment and coordination from each sector, community group, and local and state government agencies. To strengthen the institutional mechanism and coordination, the roles and responsibilities of each institution have been worked out and documented.
