- Abstract
The Earth Observations (EO) products in risk assessment find their vitality by virtue of capturing both dynamism as well as complex linkages of the residual risk to terrain, climatic, ecosystem and socio-economic factors. These products however are yet to harness fully and thus to operationalize at larger scale. Often, risk assessment, based on coarse resolution EO data, gives the impression of uniform hazard and vulnerability patterns over wide areas. As risk becomes more complex, it increasingly becomes difficult to assess both the characteristics of hazard events and potential losses. Risk analysis is normally restricted to the physical aspects of vulnerability and there are unresolved methodological problems in designing and implementing applications based on high resolution EO data, which could take into account the climatic, ecological and socio-economic aspects of vulnerability. With increasing the resolution, complexity of the models representing risk also grows. The large number of variables required differentiating complex risk patterns, and the difficulties and uncertainties in modeling the interactions and relationships between the different variables make the development of high-resolution risk models a difficult undertaking. The absence of conceptual and spatial models capable of representing the social, economic and cultural dimensions of vulnerability is another problem. Many aspects of vulnerability are difficult to quantify. The development of advanced models is still at the frontier of geo-spatial research, with the result that there are still no tried and tested procedures available for building climatic, ecological and social vulnerability aspects into risk information systems. Considering the urgent needs to have EO based risk assessment methodology which could form the basis of implementing risk reduction practices in perennial multi-hazard prone areas, the present paper illustrates an operational strategy in support of developing the crop insurance products. The effort is focused on reducing administrative and operational costs of crop insurance. It is also important to highlight that the proposed methodology takes into account the multi-dimensional vulnerability factors, besides analyzing the contemporary issues with regards to relevant EO applications, GIS and spatial modeling.
