Tipo: Abstract
Droughts have several economic, social and environmental impacts, depending on their intensity and duration. The International Drought Initiative (IDI) Secretariat has been hosted by Regional Centre on Urban Water Management (RCUWM-Tehran) under the auspices of UNESCO since its establishment in 2010. The main objective of this paper is to charting IDI’s drought risk mapping and strategy for coping with droughts considering local conditions. Recognizing risk as a factor of hazard, vulnerability and exposure divided by coping capacity (R = H×V× E/C), drought risk assessment and mapping is one pillar of the proposed strategy. It covers the identification and assessment of risks from droughts and their consequences for the future development scenarios in the target areas. There is also a need for in-depth study hydrological drought. Methods such as multivariate standardized rainfall-runoff index (MSDI) based on copula concept has been utilized for a few basins in the region. Another key element of the strategy is the study on climate change impact. The mitigation and adaptation strategy will focus mainly on drought preparedness indicators/standards and an approach to establish drought resilience communities with respect to socio-economic processes and human activities. More effective and accurate drought monitoring is part of IDI’s coping with drought and is targeted to be achieved by introducing suitable hydrological models for application in arid and semi-arid areas, especially applicable for ungauged or poorly gauged basins. The other elements of IDI’s strategy are as follows: - Surveying the current situation of drought management in different aspects such as: policy making, structural and non-structural plans; - Surveying the plans and measures of international and regional governmental/non-governmental entities involved in drought management; - Demonstration projects to improve drought monitoring through a regional, satellite-supported drought watch system, utilizing advanced geophysical data integrating satellite, radar and ground observations; - Action research on innovative community-managed drought preparedness and disaster risk management practices; - Identification of ‘no-regret’ investments in urban and rural development to accommodate climate change impacts; - Capacity development activities including training programs; and - Diagnostic assessments of executing and implementing organizations in preparation for long-term programs to build capacity and improve governance.
