“…River distance is regarded as one of the most important variables in evaluating the possible distribution of drought-affected regions. Access to water decreases as one moves away from the river, increasing vulnerability to drought occurrences (Kalura et al, 2021). In order to create the distance from rivers map, the shapefile of the main river (portion of the Greater Zab River) was extracted from the LULC layer utilizing the extraction tool in ArcGIS software in the first step.…”

Drought is among the most severe natural calamities induced by lack of water, having a negative implication on water resources and agriculture in the affected area. Drought types and severity vary by location, so understanding the spatial distribution can aid in developing measures to overcome this natural hazard. In this study, the areas vulnerable to droughts in the Mandawa watershed in the Kurdistan region of Iraq were determined by employing seven associated factors: rainfall, temperature, LULC, surface slope, soil texture, elevation, and distance to rivers. Satellite imagery of Landsat 8 OLI for 2021 was employed to create the Land Use and Land Cover (LULC) and distance to rivers maps. The elevation and surface slope maps have been generated from the Digital Elevation Model at 30 m resolution, soil texture map was extracted from The FAO Digital Soil Map of the World and the inverse distance weighting method was utilized to interpolate the rainfall and temperature throughout the watershed. Analytical Hierarchy Process (AHP) was used to create a pairwise compression matrix to obtain the weight of each parameter. In the Geographic Information System (GIS) environment, the combined impact of affecting factors was utilized to create the area's drought zonation map. The results indicated that only 5.2% and 13.8% of the study area is vulnerable to extreme and severe droughts, respectively. While more than 35% of the watershed is hardly vulnerable to droughts.

“…In general, these three types of droughts are primarily of interest to scientists. A socio-economic drought arises whenever the demand for an economic good exceeds supply significantly as a consequence of meteorological/agricultural/ hydrological droughts (Dumitraşcu et al 2018;Kalura et al 2021). All four types of droughts are interlinked; however, from the operational point of view, the droughts are commonly defined by the indices that are mostly specific to the drought type.…”

“…The concept of 'vulnerability' has been in wide use in water resources or environmental sectors in last few years (Azam et al 2021;Formetta and Feyen 2019;Fuchs and Thaler 2018;Hajra et al 2017;Kalura et al 2021;Sam et al 2017). It basically refers to the inability of a system to withstand a hazardous condition.…”

Drought is amongst the most precarious natural hazards associated with severe repercussions. The characterization of droughts is usually carried out by the sector-specific (meteorological/agricultural/hydrological) indices that are mostly based on hydroclimatic variables. Groundwater is the major source of water supply during drought periods, and the socio-economic factors control the aftermaths of droughts; however, they are often ignored by the sector-specific indices, thereby failing to capture the overall impacts of droughts. This study aims to circumvent this issue by incorporating hydroclimatic, socio-economic and physiographic information to assess the overall drought vulnerability over Narmada River Basin, India, which is an agriculture-dominated basin highly dependent on groundwater resources. A Comprehensive Drought Vulnerability Indicator (CDVI) is proposed that assimilates the information on meteorological fluctuations, depth to groundwater level, slope, distance from river reach, population density, land use/land cover, soil type, and elevation through a geospatial approach. The CDVI showed a remarkable geospatial variation over the basin, with a majority (66.4%) of the area under highly to extremely vulnerable conditions. Out of 35 constituent districts of the basin, 9, 22, and 4 districts exhibited moderate, high, and extreme vulnerability to droughts, respectively. These results urge an immediate attention towards reducing drought vulnerability and enhancing resilience towards drought occurrences. The proposed multi-dimensional approach for drought vulnerability mapping would certainly help policy-makers to proactively plan and manage water resources over the basin, especially to ameliorate the pernicious impacts of droughts.

“…The geographic and temporal extent of drought and the degree of exceptional dryness are referred to as severity. In contrast, drought vulnerability is considered to be the result of numerous human-induced situations and is influenced by land use patterns, population demographics and legislation [43].…”

Modified Hydrological Drought Risk Assessment Based on Spatial and Temporal Approaches

This study was conducted using a modified drought risk assessment in which hydrological data were processed to assess the hazards and risk of hydrological drought in Peninsular Malaysia. Although drought vulnerability and risk assessment are critical components of the drought phenomenon, the lack of a comprehensive integrated drought risk assessment in Malaysia has led to increased socio-economic impacts. The Hydrological Drought Risk Index (HDRI) illustrates the relative importance of hazard and vulnerability assessments in drought risk management for Peninsular Malaysia using the Streamflow Drought Index (SDI). This study presents an integrated drought characteristics-based risk assessment framework to improve hydrological drought risk assessment. The hydrological drought risk assessment was conducted by combining physical hazard and socioeconomic variables across the region. The periods of 1998–1999 and 2017–2018 mark the most critical hydrological droughts. The results also show that the trend of hydrological drought in river basins is towards dry conditions with no change in the foreseeable future. This study proposes a theoretical framework for effective drought risk management that can be used by the government and its stakeholders for sustainable water resource management.
