RS/GIS TECHNIQUES FOR EARLY RECOVERY

Early Recovery

By definition early recovery means: to take decisions and actions after a disaster with a view to restoring or improving the pre-disaster living conditions of the stricken community, while encouraging and facilitating necessary adjustments to reduce disaster risk.

In practice, this involves the following.

Recognizing gaps between response and recovery.Emergency relief does not address the underlying causes that resulted in

the disaster, nor does it automatically stimulate rapid recovery. In a number of situations response may even exacerbate the underlying causes of vulnerability.

A gap between the ending of humanitarian assistance and the initiation of reconstruction programming in which affected people are usually left without support for recovery

Rebuilding the conditions of risk which existed before the disaster, thus preparing the ground for future disasters and possibly contributing to increase the country's debt levels with large reconstruction loans.

Isolated and uncoordinated interventions, leading to a duplication of efforts in some areas, gaps in others and again a failure to factor in risk reduction considerations.

Rapid and visible solutions to restore normalcy, frequently at the cost of more sustainable and durable solutions that truly address the root causes of the disaster.

Supporting the development of a recovery framework as early as possible following the disaster (e.g., through information gathering, expanded consultation on relief/response priorities and decision making).

Early Recovery (cont’d)

Economic impact: Damages and losses

Damages refer to the value of affected assets (stock) like physical assets or infrastructure, final goods, raw materials, equipment and other properties. They would occur at the time of the disaster or shortly after the disaster and estimated in terms of physical units of assets that may be totally or partially destroyed

Losses refer to the value of foregone income (flows) that were affected such as production declines, reduced incomes and increased expenditures over a time period until the economy and assets are recovered.

Estimating households in the flood damaged areas The spatial resolution of the pixels in the SPOT imagery is 2. 5 meters . Villages

show up on 5 meter imagery & are identified

These villages can be listed, counted and sampled, either with high resolution (0.6 meters) imagery or on the ground to count households. Damage can be assessed if the households are being counted with interviewers.

The sampling would be greatly improved if it can be completed using a stratified design within the agricultural zones and the village selection for interviewers should be probability proportional to size (PPS) based on some size variable related to the number of households (HHs)
