This blog summaries a presentation delivered by Practical Action at an international conference titled ‘New Points of Departure in Transitioning Disaster Reduction and Sustainability Challenges’. The presentation delivered innovative research examining how effective early warning systems are for women and other marginalised gender groups in Nepal and Peru. The blog argues that often, community surveys which are conducted during a research project often miss the voices and the perspectives of marginalised gender groups. To combat this, Practical Action piloted a new approach titled the ‘Missing Voices Approach’ which included talking to specialist community-based organisations who worked with and were trusted by marginalised communities. Interviews were also conducted over the phone as opposed to visiting people’s houses and drawing unwanted attention. The new approach resulted in a much more nuanced understanding on different gendered experiences in the context of floods and early warning systems.
