Climate Change, Urbanization and the Housing Sector in Karnataka

This study aims to investigate the factors determining household behaviour regarding the adoption of renewable energy and energy efficiency in a small city. The study focuses on the implementation of two schemes: rooftop solar photo voltaic (RTPV) with net metering and the switch to LED lighting under the Domestic Efficient Lighting Programme (DELP). A household survey is being carried out in Ramanagara, a small city in Karnataka with a population of about 95,000.

Preliminary findings reveal significant penetration of solar thermal technology, but very low penetration of RTPV due to regulatory uncertainty, high capital costs, and information barriers among households and government agencies. A concerted campaign to promote LED bulbs is under way but the consequent energy savings are relatively small as they replace compact fluorescent lights. The study aims to better understand household perceptions and biases and how households would respond to different framings of incentives.

This study is supported by the Environmental Management and Policy Research Institute (EMPRI), Department of Forest, Ecology and Environment, Government of Karnataka.

Community-Based Wet-waste Composting in Bangalore, India

Urban solid waste/garbage is a worldwide problem, posing both local public health hazards and contributing to global GHG emissions. As an alternative to conventional centralized, municipality-managed solid waste disposal, many citizen-managed initiatives are also emerging. Through a combination of legislative pressure and citizen initiatives, Bangalore city has emerged as one of the pioneers in community-based garbage composting. Today, there are more than 450 residential complexes are segregating waste at source.

This project aims to study community-based garbage segregation and composting initiatives in Bangalore city in order to identify socio-technical elements that are crucial to the performance of such systems, including their methods of treating wet waste. It also proposes to carry out a desk review of experiences elsewhere, to come up with recommendations for replication and scaling in different contexts. The Bangalore experience can provide valuable insights for other parts of the world that face garbage disposal challenges. Cities of Chengdu, China and Vancouver, Canada have expressed interest in community-based composting systems.
