“…Central and south-eastern Crete, where there is also reduced precipitation, portray critical vulnerability to both drought and desertification. In all these areas, existing information portrays serious drought incidents [20][21][22]24,29,30,36,38,104] and desertification risk [40][41][42]51]. The above comparisons may indicate that there is a strong relationship between vulnerability to drought and desertification as represented by the developed indices, especially, regarding water availability and demand.…”

The degradation of natural resources at an intense rate creates serious problems in the environmental systems particularly with the compounding effects of climatic vagaries and changes. On the one hand, desertification is a crucial universal, mostly an anthropogenic environmental issue affecting soils all over the world. On the other hand, drought is a natural phenomenon in direct association with reduced rainfall in various spatial and temporal frames. Vulnerabilities to drought and desertification are complex processes caused by environmental, ecological, social, economic and anthropogenic factors. Particularly for the Mediterranean semi-arid conditions, where the physical and structural systems are more vulnerable, the abuse and overuse of the natural resources lead to their degradation and ultimately, if the current trends continue, to their marginalization. The scope of the current effort is trying to find any common drivers for the pressures of both processes. Thus, the vulnerabilities to drought and desertification are comparing by using the Standardized Drought Vulnerability Index (SDVI) and the Environmentally Sensitive Areas Index (ESAI). The indices are calculated from October 1983 to September 1996 in Greece. Greece is prone to desertification and it is often experiencing intense droughts, thus it presents an almost ideal case study area. The results may indicate that the most important factor for such procedures is the deficits in water resources, either due to lower than usually expected rainfall or to higher societal water demand.

“…Drought indices in a watershed can be analyzed using the Standard Precipitation Index (SPI) ( McKee, Doesken & Kleist, 1993 ) and Standard Discharge Index (SDI) ( David & Davidová, 2016 ). Discharges can be generated using a rainfall-runoff model called the Mock model, first introduced by FJ Mock to predict potential water availability ( Mock, 1973 ).…”

This study aimed to analyze drought conditions and evaluate irrigation water availability and household water needs in the Krueng Jrue sub-watershed, Aceh Province, Indonesia. The Z-score statistics method was developed to analyze the drought, and the Mock model was used to generate discharges. We performed model validation using linear regression, which produced a coefficient of determination (R2 = 0.90**) and coefficient of regression (r = 0.95**). In general, this area had a normal Z-score for precipitation (ZSP) class with 90 events (75%) and a normal Z-score for a discharge (ZSD) class with 89 events (74.2%). There were 0–11 (0–9.2%) moderate wet, very wet, extreme wet, moderate drought, and severe drought events. The consistency between the ZSP and ZSD indices reached 85.8%, indicating consensus between the meteorological droughts that were analyzed based on rainfall (ZSP) and hydrological droughts analyzed based on water discharge (ZSD). ZSP and ZSD indices showed negative values during the dry season (April to September) and positive values during the rainy season (October to March). There was a surplus of water availability for irrigation and household water needs during the rainy season and a deficit during the dry season. However, water deficits also occurred in certain months during the rainy rendeng planting season, for example, in October 2009, 2013, 2016, and 2017 as well as in February between 2008 to 2011 and from 2014 to 2017. This observation was probably due to the influence of global climate variables that need to be substantiated. This study offers necessary information for farmers, the community, and the local government when anticipating drought phenomenon, organizing the rice planting season, and evaluating water availability in other watersheds.

“…"The meteorological and hydrological drought is a periodic natural hazard and difficult to provide an accurate and universally accepted description of drought due to its changing characteristics and effects across different regions such as rainfall patterns, water availability, human response and resilience etc. Drought happens as a result of several variables acting on multiple time scales and varies with spatial location and temporal season; thus, drought can have impacts on various sectors especially on agriculture and ecosystems" Heim Jr., [1]; Hao and Singh, [2]. Due to its compound nature and extensive occurrence, it is challenging to describe drought and to classify its characteristics.…”

“…Ji and Peters [13] suggested the monthly SPI redirects short-term situations and its used can be associated closely to soil moisture, the three month SPI be responsible for a periodic assessment of precipitation, six and nine month SPI designates medium term movements in rainfall patterns. Although it is quite a recent index, the SPI, RDI, and SDI have been used (Nalbantis and Tsakiris [14]; Ch et al [15]; Tabari et al [16]; Ma et al [17]; Davida and Davidovaa [1] Satpute et al (2016) and Tigkasa et al [18]. The present investigation has been undertake with following objectives (a) to determine the long term trend in meteorological and hydrological drought of selected stations.…”

The meteorological and hydrological drought indices are mostly applying as a tool for observing changes in drought situations. In the present research work, evaluated the performance of two modified meteorological drought indices i.e. modified standardized precipitation index (SPIe) and modified recoinnaissance drought index (RDIe) and hydrological drought indices i.e stream-flow drought index (SDI). The effective precipitation was used instead of precipitation for modification of meteorological drought indices. The assessment of drought trends at multi-temporal such as 1, 3, 6 and 12 months was done by using popular Mann-Kendall test and the probability and return period of occurrence of severe and extreme drought condition of the meteorological and hydrological drought events. Finally results were non-significant trend (either positive or negative) at 95% confidence limit and the 43 years reoccurrence interval of extreme meteorological drought for Latur and Parabhani districts, the 10.75, 21.5 and 14.33 years return period of severe meteorological drought for Latur, Nanded and Parabhani districts. Also, the 18, 18 and 43 years reoccurrence interval of severe hydrological drought for Latur, Nanded and Parabhani districts was calculated.
