Definitions
Hazard physical conditions that has the potential for causing damage to life,
health, property or environment
Vulnerability a condition resulting from social, economic, and environmental factors or
processes, which increases the susceptibility of a system to the impact of a
hazard (drought)
Risk a combination of the likelihood of occurrence (HAZARD) and the
magnitude of the unwanted consequences (VULNERABILITY)
Ongoing work
Jianping Yan, 2010
System Vulnerability is the property of an
anthropogenic system that can be defined by the
susceptibility, coping capacity, and resilience of the
system.
Element Vulnerability refers to the degree of potential
physical damage to the target elements at risk, such as
particular crop spiece, water users, forrest biota in
response to a hazard event of a given intensity.
Drought risk assessment
Ongoing work
Sector- based risk assessment
The work is dedicated to a risk
assessment of recognized key
sectors vulnerable to drought in the
participating countries (LT, PL RO):
sector hazard assessment category of impact
Agriculture
(Act. 5.1)
SPI, HTC), PET, PDSI, CWB, EDI, Aridity
Index, NDWI, fAPAR, NDVI, CWSI, LAI
Economic (losses in crops, decline
in relevant food production)
Water
resources
SRI, Flow Index (from FDC), NDWI Social (public safety, health,
conflicts between water users,
reduced quality of life)
Forestry
(Act. 5.2)
Forest fire risk index, temperature,
precipitation, relative humidity, moisture
of forest litter
Environmental (increased
incidence of fires, damage to animal
and plant species)
Drought hazard assessment is based
upon the indicices applicable to the
participating countries (LT, PL RO)
• Selection of drought hazard indicies (region/sector)
• Identification of drought hazard assessment methods,
• Identification of impact and vulnerability estimation methods,
• Integration input information for the need of risk analysis.
Drought hazard and vulnerability assessment
Ongoing work
1. DROUGHT FREQUENCY ANALYSIS
The purpose of the frequency analysis is to determine the frequency and
severity of droughts and graphically represent the spatial distribution of drought
occurrences.
The SPI method is designed to be flexible in terms of drought duration specified by users.
Short time scales (e.g., 3 months) may be important for agricultural practices while long time
scales (e.g., one year or longer) may be vital for water supply management interests.
Maps representing spatial distribution of the probabilty of
occurence and duration drought of different severity .
The resultant frequency data are intended for integration with the
results of the drought vulnerability analysis to identify areas subject to drought risk.
(1) Drought frequency analysis (HAZARD),
(2) Assessment of drought impact on a given area (EXPOSURE),
(3) Vulnerability analysis (ELEMENT VULNERABILITY)
(4) Integration of these components to a form risk maps (RISK)
Risk mapping
Ongoing work
2. GIS-BASED ASSESSMENT OF DROUGHT IMPACT AREAS
Data sources:
The meteorological conditions: precipitation, temperature, wind, slope
exposure, relative humidity, cloud cover, and evaporation and transpiration
data.
The environmental conditions: geology, slope, soil types, vegetation
types and coverage, water resources.
The land use and management data: crop information and farming
practices for crop and livestock, livestock population inventories.
The infrastructure conditions: population settlements and communities,
hotels and tourist zones, dams and storage reservoirs, desalinization and
water treatment plants, waste water treatment facilities, irrigation and
water distribution systems, water catchment systems.
- Identifying & categorizing elements at risk: crop type; forest biota; population, etc.
- Inventory mapping:
– Resolution
and seasonality
– Data format
– Analysis unit
Ongoing work Risk mapping
Developing Vulnerability Functions
for Drought Risk Assessment
- Loss-Intensity Matrix for Drought
- Vulnerability Functions
3. VULNERABILITY ANALYSIS Vulnerability functions are created to calculate
potential damage or loss to a given element at
risk against a specified event intensity.

Jianping Yan, 2010
based onTsakiris et al., 2010
water resources sector:
1) water supply locations;
2) population demographic information;
3) drought hazard map based on SRI
Exmaples of the combination of GIS leyers
regarding the risk assessment for:
agricutural sector:
1) land use;
2) crop type;
3) population demographic information;
4) drought hazard map based on SPI
The risk assessment involves both GIS data-gathering and data creation so as to compile asset layers and analytical layers for a visual presentation of risk.
GIS offers the ability to integrate many different types of data through the use of common geography. Each feature is linked to a position on the graphical image of a map. Layers of data are organized to be studied and to perform statistical or spatial analysis.
GISs allow users to analyze geographic phenomena within areas of interest, thus leading to a better understanding of relationships and to provide a helpful tool in decision-making.
The combination and content of leyers depends on purpose. This analysis include methods to overlay, query, highlight, and select layers that are determined as being critical to the examination of the potential vulnerability of the drought impact sectors. The analysis consisted of deriving new maps of the likely occurrence or magnitude of a particular phenomenon based on the established relationship between the existing maps layers.
Ongoing work Risk mapping 4. INTEGRATION TO FORM OF RISK MAPS
4. INTEGRATION OF THESE COMPONENTS TO FORM OF RISK MAPS
The integrated risk can be represented by a two-dimensional matrix that
classifies risks into three categories (low, moderate, high) based on the combined
effects of their likelihood (HAZARD) and consequence (VULNERABILITY).

Where we search for expertise? • Partner countries? • IDMP CEE countries? • Other projects? • Literature? • Develop new ones?
