There is little evidence of weather-related impacts on conflict risk or prevalence, but the region is under-studied in general . Climate stressors may have contributed in part to local-level conflicts in Bangladesh and Nepal  and intensified water use conflict in peri- urban areas . In the future there is the potential for climate change to stretch the effectiveness of transboundary water agreements by raising regional geopolitical tensions  or to generate water use conflicts between hydropower and irrigation within countries . Climate change may have an impact on conflict by affecting food security . There may be greater military involvement in humanitarian response to cyclones, flooding and to other impacts of climate change that might contribute to increased instability .
