This paper aims to model risk assessment due to the natural hazards and public policy in North East India by considering key natural hazards including floods, earthquakes, landslides, wildfires and soil piping. The effectiveness of existing public policies for disaster-affected areas in the region were evaluated. The influencing parameters of policy formulation were topography, demography, vulnerability and human behaviour. Currently, public policy frameworks were formulated primarily based on social, economic, socio-economic and socio-environmental aspects. However, there is a significant gap in integrating scientific, socio-economic and scientific-economic considerations. In addition, a risk in Northeast India is the impact of human-wildlife conflict, which is recognized as an indirect risk factor in policy development. Key risk elements include the extent of flood-affected areas and regional population data. On the other hand, risk indicators encompass economic decline, loss of life and reduced domestic production. Effective disaster mitigation policies must incorporate scientific solutions including disaster risk mapping, impact forecasting, early warning systems and preparedness measures. The role of disaster risk reduction managers is also redefined to enhance their effectiveness. The proposed disaster risk reduction strategies align well with international case studies, ensuring a comprehensive and globally relevant approach.

摘要

This paper aims to model risk assessment due to the natural hazards and public policy in North East India by considering key natural hazards including floods, earthquakes, landslides, wildfires and soil piping. The effectiveness of existing public policies for disaster-affected areas in the region were evaluated. The influencing parameters of policy formulation were topography, demography, vulnerability and human behaviour. Currently, public policy frameworks were formulated primarily based on social, economic, socio-economic and socio-environmental aspects. However, there is a significant gap in integrating scientific, socio-economic and scientific-economic considerations. In addition, a risk in Northeast India is the impact of human-wildlife conflict, which is recognized as an indirect risk factor in policy development. Key risk elements include the extent of flood-affected areas and regional population data. On the other hand, risk indicators encompass economic decline, loss of life and reduced domestic production. Effective disaster mitigation policies must incorporate scientific solutions including disaster risk mapping, impact forecasting, early warning systems and preparedness measures. The role of disaster risk reduction managers is also redefined to enhance their effectiveness. The proposed disaster risk reduction strategies align well with international case studies, ensuring a comprehensive and globally relevant approach.
