The concept of vulnerability and risk to environmental disasters, coupled with its geographic or spatial perspective, gives us meaningful and useful insights. In particular, vulnerability and risk mapping assist in spatial analyses towards the formulation of more effective ways to respond in terms of policy and decision-making as well as strategizing adaptation and mitigation at various scales.
The risk maps, in general, aid in identifying areas where further study is both important and urgent. Strengthening of the framework, R = HEV, is needed to more accurately portray actual risk conditions. Techniques may include considering collateral hazards, varied exposed elements, and multiple vulnerability indicators.
Moreover, national-scale mapping reveals trends and themes across categories that may potentially be correlated. Future directions, therefore, can also include comprehensive studies to establish if such correlations do exist, and how these connections influence vulnerability and risk assessment.
Given the findings across categories, it is recommended that the next phase of risk mapping include the following activities:
- Review and reformulate framework for determining risk, (R = H*E*V) and consider:
- possible collateral hazards,
- livelihood as well as lives exposed,
- multiple vulnerabilities, and
- efforts at adaptation, prevention and mitigation that may reduce risk
- Determine the effect of the presence of urban centers, and quantify access to urban centers using maps of location, slope and transportation.
- Create ecological disaster risk maps.
- Establish correlations among the anthropogenic, ecological and disaster risk maps.
- Conduct localized disaster risk mapping in high-priority areas.
