Handloom weaving is a vital source of livelihoods and cultural heritage in Sri Lanka. This report examines the impacts of rising temperatures and heat stress on Sri Lanka’s handloom sector, with a focus on Maruthamunai in the Eastern Province, Sri Lanka. It combines workplace surveys, field observations, and WBGT analysis to document the ways in which extreme heat affects weavers’ health, productivity, and income security.

The findings highlight structural vulnerabilities such as limited ventilation, high energy costs, and an ageing workforce, which heighten the sector’s exposure to climate risks. The report also outlines a set of adaptation measures, from improved cooling and ventilation to occupational safety, microfinance, and policy support to strengthen resilience, protect livelihoods, and sustain the continuation of traditional weaving practices.
