“…Drought is a climatic phenomenon that endangers tropical countries every year by the impacts of global warming which causes extreme climate [1] changes from year to year [2], [3]. Drought is one of the most complex and poorly understood disasters that has the greatest impact on humans and usually affects large areas [4].…”

Drought causes crop failure in the agricultural sector and a limited supply of clean water. Land damage due to drought in Lamongan has reached ±12,000 ha in the last decade. The lack of information regarding drought disaster mitigation resulted in quite large losses in several agricultural sectors. The purpose of this study is to develop a decision support system (DSS) that can provide information regarding the identification of drought-prone areas. The fuzzy analytical hierarchy process (FAHP) method is implemented with four criteria: rainfall intensity, slope, soil type, and distance to the river. FAHP is good for processing the weighting of several criteria and categories to produce good choices. Results, the tests carried out there were 20 sub-districts prone to drought, with an accuracy rate of the FAHP method of 85%. The average value of respondent satisfaction averaged 97.2%. DSS application can provide the status of areas prone to drought. For future studies, the temperature and evapotranspiration parameters can be added, to provide better results.

“…However, these effects can be divided into two groups, direct and indirect. In societies whose economy is based on agriculture, the direct effects of drought appear in the form of reduced food production due to reduced cultivation and crop yields (Dariusz et al, 2021; Das et al, 2021). The impacts of drought and dryness on the environment in the study area can include consequences such as damage to animal species, including hydrological effects, including damage to plant communities, effects on air quality (soil and pollution), landscape quality and vision (vegetation and dust), infrastructure and welfare facilities and loss of life, including increase water and wind erosion, reducing soil quality, severe soil erosion due to unbalanced distribution of precipitation and irregularity in the ecological cycle and climatic conditions (Fooladi et al, 2021; Javadinejad et al, 2021; Rezaei, 2021).…”

The consequences of climate change, primarily due to natural and human factors, have caused many problems in the last decade that have affected different sections of society. One of the most important consequences is the occurrence of natural atmospheric—climatic disasters (drought). One of these regions is Iran in the Middle East, which has been suffering from this drought in the last decade. This investigation aims to evaluate and monitor drought and its impacts on environment changes in Iran. To conduct this research, the TERRA satellite data and the MODIS sensor were used over a 21‐year period, and the Normalised Differential Vegetation Index and Palmer Drought Severity Index Indicators were used to monitor drought and to estimate the soil moisture by the Soil Moisture Calculation satellite. Finally, to estimate the amount of precipitation and evapotranspiration, cumulative precipitation and real evapotranspiration, actual evaporation and transpiration were used. Findings showed that in the investigation region, the severity and frequency of drought have increased in recent years. Soil moisture has also decreased, indicating the inverse relationship between drought intensity and soil surface moisture, meaning that as the intensity of drought increases, the amount of soil surface moisture decreases. However, in the investigation region during the study course, the accumulation of rain showed a direct relationship with evaporation and transpiration. The highest monthly drought intensity of Palmer was 5.65% in May 2000. Also, the highest amount of wet year in November 2018 is 3.6%. The highest amount of rainfall was 61.25 mm in October 2018. Based on the results obtained in this research, drought has occurred in the investigation region in recent years, the intensity of which in the south, eastern and centre half of the country, especially the provinces of south Khorasan, Semnan, Hormozgan, Sistan and Baluchestan, Khuzestan and Ilam more it has been more than other provinces. To manage and control drought in the investigation region, in the various sectors affected by drought (agriculture, environment, surface water resources, forests, pastures and watershed management and natural ecosystems) strategies and plans in the short term, medium‐term and long‐term in line with natural and human factors and climate change to be adopted.
