Estimation of Damage Assessment and Loss Assessment (DALA)
The methodology developed by the UN Economic Commission for Latin America and the Caribbean (UNECLAC) is used to estimate the effects and
impact of natural hazards. DALA was developed in the 1970s and since then has been strengthened, simplified and customized for application in
different areas of the world. DALA bases the assessment of disaster impacts on the overall economy of the affected country as well as on household
level. This provides a basis for defining the needs for recovery and reconstruction following any disaster.
- The replacement value of totally or partially destroyed physical assets that must be included in the reconstruction program
- Losses in the flows of the economy that arise from the temporary absence of the damaged assets
- The resulting impact on post-disaster economic performance, with special reference to economic growth, the government’s fiscal position and
the balance of payments.
To amplify the scope of the assessment and reduce the cost of conducting parallel needs assessments, DALA is complemented by sector specific
assessment outputs, which provide a more detailed insight into the socioeconomic impact. This combination of assessments is then used to formulate
the recovery and reconstruction needs into a Joint Damage, Loss and Needs Assessment (JDLNA).
A unique aspect of the JDLNA is that it is led by the Government of the affected country and assisted by a multidisciplinary, multi-agency team. The
- Damage, loss and macro-economic impact on the affected economy
- Impacts on livelihoods, incomes, and human development
- Short, medium and long term recovery and reconstruction needs
- Measures for Disaster Risk Management.
In addition to undertaking disaster assessments, upon the requests of governments, ECLAC provides training to national personnel in the use of the
The ultimate goal of the ECLAC assessment methodology is to measure in monetary terms the impact of disasters on the society, economy and
environment of the affected country or region. National accounts are used as a means of valuation, supplemented with procedures for specific
estimates such as environmental damages and the differential impact on women.
Application of this methodology provides affected countries or regions with the means to determine the value of lost estimates and define
reconstruction requirements. It enables the identification of the most affected geographical areas and sectors, together with corresponding
reconstruction priorities. In addition, it provides a way to estimate effects on economic flows, the affected country's capacity to undertake
reconstruction on its own and the extent to which cooperation are needed. Moreover, it can be used to identify the changes to public policy and
development programmes/plans needed to deal with needs arising from the disaster and to avoid undesirable effects in economic performance and
Assessment activities described should be carried out when emergency stage has been completed or is nearing conclusion, so as not to interfere
with those actions and to ensure the availability of the necessary personnel and basic information. They are intended to facilitate the identification of
needs and priorities for the reconstruction stage.
