The understanding of vulnerability both at the household and individual level, as well as the sectoral and community level, was enriched by the research on social vulnerability and gender under the project entitled “Building Capacity to Adapt to Climate Change in Southeast Asia.” The study was conducted in the province of Laguna in the Philippines with the aim of identifying who are vulnerable, and analyzing why they are vulnerable, and how they adapt to the risks of climate change and climatic hazards. The gender perspective in the research process was given emphasis. The study looked into how climate change-induced hazards affected men and women differentially, how they cope with these hazards, and in what household adaptation measures do women play important roles. Findings discussed in this publication came from data generated from a number of methods, including a barangay-level survey, focus group discussions, key informant interviews, and cases from in-depth interviews.
