Participatory 3-dimension mapping: A tool for encouraging multi-caste collaboration to climate change adaptation and disaster risk reduction

This article reflects upon the use of participatory 3-dimensional mapping (P3DM) for facilitating the collaboration of different castes in disaster risk reduction (DRR) and climate change adaptation (CCA). Unequal power relationships amongst upper and lower castes has indeed been identified has a major driver of people's vulnerability to natural hazards, including the negative effects of climate change, in Nepal and elsewhere in South Asia. However, this does not prevent the members of all these castes, including the lowest untouchables, to display significant capacities in facing these natural hazards and changes in climate patterns. It is therefore similarly important to harness those capacities and address the unequal power relationships underpinning vulnerability. Achieving these goals requires fostering dialogue amongst upper and lower castes as well as with other stakeholders of DRR and CCA, e.g. scientists, NGOs, government agencies, which often tend to work with a single caste because it is easier. P3DM provides a platform for such a dialogue as it makes the knowledge of every caste tangible and credible to others. This proves essential in both assessing and planning for reducing the risk of disasters and adapting to climate change. This article particularly documents activities conducted in a small village of the Terai plain of Nepal frequently affected by flooding.
