Recently, industrialization, urbanization and population growth are recognized as the most pervasive socioeconomic drivers contributing to land use/cover change on a global scale. However, the transition to irrigated agriculture, which has been initiated for the last 40 years in the Harran Plain, which is a semi-arid region where dry farming has been practiced for years, has brought along some socioeconomic driving forces. In this context, this study adopted two categorical approaches. The first is excessive-irrigated areas, danger of salinization, lack of drainage systems, unplanned urbanization, deterioration in groundwater quality, increasing population and migration. The second is the gradual rise of groundwater level triggered by excessive and unconscious irrigation. The implications caused by this rise are discussed in this study. Besides, in this study, the impact of these two categories was determined by the analysis of land use/cover changes. Our study utilized remote sensing and geographical information system to define and predict land use and land cover changes in the GAP area of southeastern in Türkiye. We found that in a 40-year period (from 1990 to 2020), a semi-arid Harran Plain has lost 12.33% of its steppe areas and 29.93% of dry agricultural areas. In addition, 33.44% from irrigated agricultural areas, 3.34% from forest areas and 5.48% from residential areas have gained. The results indicated that despite the decrease in dry agriculture and steppe, the increase in irrigated agricultural production, build-up area and woodland is the major driving forces contributing to land use-change in the Harran Plain. The study will contribute to the development of sustainable urban land use planning decisions and to predict possible future changes in the growth patterns in the plain.

Timely and accurate detection of land use/land cover (LULC) change is important for the macro and micro level sustainable development of any region. For this purpose, geospatial techniques are the best tool for change analysis as they supply timely, cheaper, precise and up to date information. This paper examines the spatial temporal change trend in LULC in the case of Central Haryana. Landsat 2, 3, 5, 7 and 8 images for the years 1975–2020 for pre and post monsoon periods were analyzed for the study. Radiometric correction was performed to derive better information. ArcGIS 10.2 and ENVI 5.3 are used for thematic layout and thematic change preparation. An unsupervised classification using ERDAS IMAGINE 2015 has also been done to classify study area in eight classes. The year 1975 is considered as the base year for change detection analysis. Results showed an increasing trend for the land use classes of built up, water body, and agricultural land without waterlogging in the pre and post monsoon periods between 1975 and 2020. Remaining land use classes of agriculture with waterlogging, open waterlogged area, vegetation and fallow land/sand dunes decreased during the same period. Increased human activities have changed the LULC in the region and have had a great impact on its sustainable regional development.
