Flood risk management under climate change: a hydro-economic perspective

摘要: Most developing countries, like Nepal, are expected to experience the greatest impact of climate change (CC) sooner and on a greater magnitude than other developed countries. Increase in frequency extreme rainfall events is likely increase risk flooding rivers. The West Rapti River basin one most flood prone also dynamic economically important basins Nepal. This study elicits willingness pay (WTP) from local people reduce risks possible floods due CC. WTP for mitigation different hazard zones scenarios were determined using referendum method face questionnaire survey. From total 720 households across all zones, stratified randomly selected sample 210 was surveyed. included range socio-economic backgrounds. average varied by zone within each zone, CC-induced scenarios. respondents highest critical followed moderate low zones. Similarly, increased with increasing magnitudes variation indicate levels perceived severity. Moreover, introduction concept ‘man-day’ or ‘labour-day’ research novel applicable methodological approach, particularly South Asian region. findings this useful policy implications design participatory management plans river basin.
