Southeast Anatolia Region, where Turkey's summer-winter differences were experienced as a region, was preferred in this study. Daily precipitation and daily temperature data for the 1950-2019 period were provided for analysis. However, due to data deficiencies, Adiyaman, Batman and Kilis stations were worked in the 1959-2019 period and Sirnak station in the 2000-2019 period. All data have been tested for homogeneity. According to the parameters used in this study, comparisons were made between the indices. It is divided into 4 according to the parameters used. Although the parameter used is the same, each index has drawn different results due to time differences. Dry results were obtained across the entire station from the methodology of the EDI (as used daily rainfall data). In addition, due to the low precipitation in the index, dry results were obtained in the RAI. Normal results were obtained with other precipitation-based drought indices. According to EDDI results, the driest month is April. During the 12-month seasonal period, only 5 months have passed in the form of no drought. According to SPEI and RDI values, normal results were achieved at all stations. Moderately and severely dry conditions sometimes occur, extremely dry have rarely been seen. RDI has been identified to have a more drought duration than SPEI. According to PCI and HTC (based on precipitation and temperature), EDI and RAI results (precipitation-based), the region is dominated by drought. When viewed on a station-by-station basis, drought has been observed at stations in the borders.

“…Similarly, Prăvălie [63] confirmed a pronounced alteration in the bioclimate over a longer five-decadal period in southern Oltenia, where after 1980, the dominance of the semi-arid conditions is more evident. Long-term trends of the IDM in the study of Vlăduţ and Licurici [64] resulted in the nonstatistically significant tendency of bioclimatic change over the entire Oltenia region between 1961 and 2015. Lungu et al [65] highlighted Dobrudja's (south-western Romania) warmer and drier bioclimatic trend based on the computation of the index from the recorded climate data between 1965 and 2005.…”

Projecting Bioclimatic Change over the South-Eastern European Agricultural and Natural Areas via Ultrahigh-Resolution Analysis of the de Martonne Index

The changing climate is closely related to changes in the bioclimate. This research deals with the present bioclimate and its projected evolution over the entirety of the natural and agricultural lands of south-eastern Europe and individual countries (Bulgaria, Greece, Kosovo, N. Macedonia, Romania, and Serbia). For this purpose, an ultrahigh spatial resolution of the de Martonne bioclimatic index pattern was elaborated and analysed for the first time. The survey is performed over the reference period (1981–2010) and future time frames (2011–2040; 2041–2070; 2071–2100) under SSP370 and SSP585 emission scenarios. On a territorial level, both natural and agricultural areas appear as highly impacted by the future changes of bioclimate; the highest xerothermic trend is expected to influence the latter areas, mostly in 2071–2100 and under the higher emission scenario. The natural areas will face an expansion in the semidry class from 0.9% (of the total area) during the reference period to 5.6% during 2071–2100 under the RCP8.5 scenario as the dominant extremely humid class falls from 53.5% to 32.9% for the same periods and scenario. On the other hand, agricultural areas will face a more intense xerothermic alteration going from 4.9% to 17.7% for the semidry class and from 41.1% to 23.5% for the dominant very humid class for the same periods and scenario. This study presents the spatial statistics per country for the selected scenarios and periods to provide information for stakeholders. This study’s results highlight the necessity for intensifying adaptation plans and actions aiming at the feasibility of agricultural practices and the conservation of natural areas.

“…Many previous studies have used aridity indices in different regions, as they measure the degree to which a region's climate lacks effective and life-promoting moisture [7]. Spatial and temporal variations of several indices were analyzed for Bahrain [8], Bangladesh [9], Turkey [10][11][12][13], Greece [7], Romania [14][15][16][17], Ethiopia [18,19], Iran [20][21][22], Pakistan [23], IP [24][25][26], Iraq [27,28], Extremadura in southwestern Spain [29], Serbia [30][31][32], India [33,34], the Middle East and North Africa [35], Calabria in Southern Italy [36], and southeastern Europe [37]. However, these studies were conducted over historical periods and do not project potential shifts under future climate change scenarios.…”

The assessment of aridity conditions is a key factor for water management and the implementation of mitigation and adaptation policies in agroforestry systems. Towards this aim, three aridity indices were computed for the Iberian Peninsula (IP): the De Martonne Index (DMI), the Pinna Combinative Index (PCI), and the Erinç Aridity Index (EAI). These three indices were first computed for the baseline period 1961‒1990, using gridded observational data (E-OBS), and subsequently, for the periods 2011‒2040 (short range) and 2041‒2070 (medium range), using an ensemble of six regional climate model (RCM) experiments generated by the EURO-CORDEX project. Two representative concentration pathways (RCPs) were analyzed, an intermediate anthropogenic radiative forcing scenario (RCP4.5) and a fossil-intensive emission scenario (RCP8.5). Overall, the three indices disclose a strengthening of aridity and dry conditions in central and southern Iberia until 2070, mainly under RCP8.5. Strong (weak) statistically significant correlations were found between these indices and the total mean precipitation (mean temperature) along with projected significant decreasing (increasing) trends for precipitation (temperature). The prevalence of years with arid conditions (above 70% for 2041‒2070 under both RCPs) are projected to have major impacts in some regions, such as southern Portugal, Extremadura, Castilla-La Mancha, Comunidad de Madrid, Andalucía, Región de Murcia, Comunidad Valenciana, and certain regions within the Aragón province. The projected increase in both the intensity and persistence of aridity conditions in a broader southern half of Iberia will exacerbate the exposure and vulnerability of this region to climate change, while the risk of multi-level desertification should be thoroughly integrated into regional and national water management and planning.
