In Uzbekistan, more than half of population lives in rural area, their well-being depends on quality of land and water resources availability. Quality of land is determined by ameliorative indicators: ground water depth level, ground water salt amount and salinity of soil. These factors do not appear naturally but rather due to the human activity. Inefficient irrigation and excessive consumption of irrigation water on irrigated land in Boyavut District of Syrdarya region of Uzbekistan within several decades have led to a salinization of soil. The primary objective of this article is determination of the level of salinity of soil for modelling spatial distribution of soil salinity throughout an irrigated land by using GIS technology. This technology is focused on automation of development and creation of ameliorative maps, while totally eliminating manual operations. Nowadays, ameliorative expedition specialists still create cadastral map using tracing paper over the marginal areas within irrigated lands based on their ameliorative conditions and by selecting from the three thematic maps and then selecting the poorest conditions of ameliorative indicators. The suggested technology is designed for professionals of cadastral subdivisions of regional ameliorative expeditions, who use the GIS-based software, such as ArcView 3.2. or ArcGIS 10x; their duties include creating of thematic maps based on salinity levels of irrigated lands. Exact coordinates of collection sites of soils samples (collected in 2018-2019) were determined using GPS. The Inverse Distance Weighting (IDW) interpolation method was applied to use that data to create ameliorative maps categorized by the salinity levels (non-saline, slightly saline, saline area and highly saline areas). Those maps were then analysed to develop procedures on how to improve ameliorative conditions of irrigated areas.

The article analyzes the existing procedure for entering information on the boundaries of zones with special conditions for the use of territories in the Unified State Register of Real Estate using the example of flooding zones. The basic regulatory documents governing the procedure and procedure for establishing flood zones are identified, in which gaps are identified in the requirements for the content of the work to determine the boundaries of such zones and assess their accuracy. In this connection, it is proposed to use the algorithm developed by the authors to determine the boundaries of the zones of underflooding development based on the analysis of the hydrographic network and digital terrain model using GIS technologies. This methodology is aimed at an operational assessment of the conditions of built-up and built-up territories, which allows to reduce the financial costs of conducting expensive engineering surveys, the need of which remains to clarify the results of computer mapping in the most critical areas. The norms of accuracy of determining the boundaries of flood zones are proposed, which will correspond to the accuracy of determining the boundaries of the lands of the water fund. In order to test the developed algorithm, we chose the territory of the Ob-Tomsk interfluve, for which zoning was carried out according to the depth of groundwater and the territories of moderate and severe flooding were identified for the purpose of further more detailed study.

The land suitability supply the decision-making for the planning and design and rational distribution, and prevent the unreasonable use of land. In order to evaluate the land suitability of cotton, the research which makes use of ArcGIS establishes the common model including the partition of evaluation unit, the selection of evaluation factors, the determination of the weight, and form a fast, simple and practical evaluation process. The results illustrate that 61 percent of the study area are suitable for the cotton’s growth; the content of salt is the main limit factor of the cotton’s growth.

Based on the application of the Revised Universal Soil Loss Equation (RUSLE) and modern GIS technology (ArcGis 10.2.2.), the article presents a method for calculating the erosion potential of the relief (LS) of the Duruji river basin (north-eastern part of Georgia). The most erosion-hazardous areas have been identified, which is approximately 75.1% of the total area of ​​the Duruji river basin. It has been established that special attention should be paid to a detailed study of the identified erosional areas of the Duruji river basin, taking into account all the influencing factors on soil erosion for the successful design of erosion control measures.

This study is aimed at designing an algorithm to analyze the effects of climate on crops. Two different crops named sorghum and sesame were selected as a case study in Doka area in Sudan because this area receives good amount of rain suitable for the production of the selected crops, so GIS technology was used to determine the vegetation map of the study area. The idea applied was to select a sample of data for a period of ten years and determine the productivity of the crop in this period and then the production values of these years were arranged from the highest value of productivity to the lowest value and then determined the highest value of productivity in these years and note to the values of the climate effects (the best climatic conditions led to high productivity) which led to predicate and determine the crop productivity based on climate affected values, cultivated area (CA) ,Harvested Area (HA) , Damage Area (DA) and the area affected by Evapotranspiration Negatively (AEVN), so the results which have been accessed are that the algorithm can calculate crop yield with high accuracy because it depends on all climatic elements that affect crop growth, so all meteorological organizations in the world can use this algorithm principle to assess crop yields and Accurate assessment of production.

Perairan Pulau Poteran merupakan salah satu wilayah yang berlokasi di Kabupaten Sumenep, Jawa Timur. Budidaya rumput laut di Pulau Poteran terdapat beberapa kendala dalam pengembangannya, yaitu dari sarana prasarana perikanan yang kurang memadai, keterbatasan pemahaman sumber daya manusia, modal, kelembagaan serta penentuan lokasi budidaya rumput laut. Penggunaan teknologi Sistem Informasi Geografis (SIG) di bidang kelautan dapat memberikan gagasan yang baru dalam kesesuaian lahan untuk budidaya rumput laut. Tujuan dilakukan penelitian ini adalah menganalisa lahan yang berpotensi untuk budidaya rumput laut di perairan Pulau Poteran dan mengetahui luas lahan yang efektif untuk pengembangan budidaya rumput laut di perairan Pulau Poteran. Metode penelitian yang digunakan adalah metode eksploratif dengan pendekatan analisa kuantitatif untuk mengetahui tingkatan dan luasan kesesuaian lahan budidaya rumput laut di perairan Pulau Poteran. Hasil penelitian menunjukkan bahwa luas untuk kategori sangat sesuai (S1) sebesar 7.335,59 ha, sedangkan untuk kategori sesuai (S2) memiliki luas sebesar 17.990,11 ha dan kategori tidak sesuai (S3) memiliki luas sebesar 24.665,28 ha. Luas lahan yang efektif untuk pengembangan budidaya rumput laut di perairan Pulau Poteran sebesar 4.401,35 ha (60% dari luas sangat sesuai) dengan jumlah rakit yang dioperasikan sebesar 785.955 unit dengan ukuran rakit 7 x 8 m. The territorial waters of Poteran Island are one of the areas located in Sumenep Regency, East Java. There are some problems in seaweed cultivation of Poteran Island, which are facilities, fishery infrastructure, limited human resources, financial, and institutional and the determination of the location of seaweed cultivation. The use of Geographic Information System (GIS) technology in the marine field can give new idea in land suitability for seaweed cultivation. The purpose of this research is to analyze the potential for seaweed cultivation in the waters of Poteran Island and know the effective land area for the development of seaweed cultivation in the waters of Poteran Island. The research method used is an exploratory method with a quantitative analysis approach to determine the level and extent of the suitability of seaweed cultivation in Poteran island waters. The results showed that the area for the very suitable category (S1) amounted to 7,335.59 hectare, while the corresponding category (S2) has an area of 17,990.11 hectare and the unsuitable category (S3) has an area of 24,665.28 hectare. Effective land area for the development of seaweed cultivation in the territorial waters of Poteran Island amounted to 4,401.35 hectare (60% of the area is very suitable) with the number of rafts operated by 785,955 units with a raft size of 7 x 8 m.
