The environment is changing quickly and it is ever more burdened in connection with the greater needs of human society. This fact has increased efforts to improve the management of land and natural resources and the necessity to evaluate them. Land valuations become more important as the land consumption increases. Soil needs to be evaluated in the whole context of how its quality is affected and the values it provides. The concept of ecosystem services offers this holistic view. This paper defines ecosystem services (ES), the various linkages between soil properties, their functions and benefits, the assessment of soil quality using indicators and then briefly mentions EU environmental assessment methods and terms used in the context of ES. The article also mentions frameworks with which to assess and evaluate the soil quality that can be divided into two groups. The first group is comprised of a framework of indicators that describe the current state of the soil system assessment for evaluating the quality of the agricultural land. This is based on a detailed measurement of the terrain, a statistical analysis of soil databases or processing the status of specific threats to the soil. The second group is comprised of a framework of indicators focused on changes in the soil quality and applied soil management. These frameworks deal with the productivity of the soil in various systems of farming, compare agricultural systems or discuss the advantages of soil biota as indicators of soil quality in detail. Many of the designs of the soil quality indicators focus on the soil management in the context of a single discipline such as agriculture or water pollution. There are concepts for considering the soil quality in regional planning.

The formation of an economically developed management system for the country's agro-industrial complex cannot be considered only from the point of view of a separate science. Land resources are the source of profit, which is involved in almost all sectors of society. Land preservation and improvement is required to ensure an economic security and competitiveness of each region of the Russian Federation). The dynamics of changes in the areas of Svetloyarsky district of the Volgograd region in the context of municipalities is analyzed. The actual deviation of the area of Privolzhsky rural settlement amounts to 2,3 % of the statistical data. The boundaries and areas of the used plots of arable land in the Raigorod settlement do not coincide with the data of the state cadastral registration, the discrepancy of only one land plot is 422,44 hectares. By implementing GIS-technologies, the data were obtained for 2355 arable land plots, whereof the irrigated land area amounts to 52138 hectares, instead of the potentially possible 19455 hectares, that exceeds the settlement's capabilities by 2,7 times according to the statistical data.

Scientific evaluation of the land is essential in order to understand the suitability for agricultural and non-agricultural purposes and identification of capabilities and constraints of the land for various crops and their cultivation helps in appropriate and sustainable usage. In order to uplift the production, productivity as well as profitability from a farm land, the knowledge regarding various land resources and soil properties become pre-requisites. In this, direction, a land inventorization was carried out using RS and GIS techniques. The prime objective was to carry out land evaluation studies based on land based on land capability classification and suitability of lands for commonly cultivated crops in the region. Soil morphological features, physical, physico-chemical and fertility properties of the land were analysed and the results indicated that the soils are good in inherent properties even with the slight variation in the morphological and physicochemical properties. Land evaluation based on Land Capability Classification (LCC) revealed that, all the blocks fall under Class-IV with some of the limitations like, erosion, texture and low organic carbon content in soils. Suitability of land to the crops indicated that there are limitations with respect to erosion, slope and soil fertility. Based on the obtained results, corrective measures were suggested for all the blocks to reduce the erosion losses improve the soil properties for higher productivity of the cultivated crops. The study concludes that variation in soils in all blocks is due to the close relationship between soils, physiography and climate which are interrelated.

The purpose of this study is to design an interface and an interaction model using user-centered Design approach. The model-built first aim is to assist the development process of a 3-dimensional geographic information system (3D GIS). The second aim is to ensure that the system that is built meets the needs of the user. GIS has been applied in various fields. In the agriculture field, GIS is often used to assist land evaluation and commodity selection. 3D GIS can provide map visualizations that are similar to actual earth topography. This advantage can minimize the user's cognitive load when using the map. Developing 3D GIS requires more complex components than 2D GIS. This study proposes an interface and interaction model for 3D GIS in scope of agricultural commodities selections. This study has five main stages. The first stage is software requirements Analisys. The second stage is data and content analysis. At this stage, data analysis is carried out to then build a data model to manage geocontent. The third stage is User Interface design. At this stage, an interface model is created as guidelines to arrange the 3D map layout. The fourth stage is the development of the interaction model to analysis of potential user actions and feedback of the system. The last stage is prototype development and evaluation. The prototype is evaluated by involving farmers to measure the adequacy of the data. A heuristic evaluation focused on eight statements was carried out. Based on the evaluation process, in general, most users agree with the statements made. It means that the model built meets the needs of the user. This model is expected to make it easier for software developers to build 3D GIS and ensure the farmer’s need in the sistems are meets. It’s hoped that combining visual elements and interaction can increase the usability level of 3D GIS.

Land evaluation is imperative for its efficient use in agriculture. Therefore, this study aimed at assessing the suitability of a region in West El-Minia for cultivating some of the major crops using the geographical information system (GIS). The results focus on allocating space for cultivating sugar beet and utilizing the free period of sugar beet in other crops. This exploitation helps to maintain the quality of the land and increase its fertility by using crop rotation with integrated agricultural management. A machine learning technique was implemented using the random forest algorithm (RF) to predict soil suitability classes for sugar beet using geomorphology, terrain attribute and remote sensing data. Fifteen major crops were evaluated using a suitability multicriteria approach in GIS environment for crop rotation decisions. Soil parameters were determined (soil depth, pH, texture, CaCO3, drainage, ECe, and slope) to characterize the land units for soil suitability. Soils of the area were found to be Entisols; Typic Torrifluvents, Typic Torripsamments and Typic Torriorthents and Aridsols; Typic Haplocacids, Calcic Haplosalids and Sodic Haplocalcids. Overall, the studied area was classified into four suitability classes: high “S1”, moderate “S2”, marginal “S3”, and not suitable “N”. The area of each suitability class changed depending on the crop tested. The highest two crops that occupied S1 class were barley with 471.5 ha (representing 6.8% of the total study area) and alfalfa with 157.4 ha (2.3%). In addition, barley, sugar beet, and sorghum occupied the highest areas in S2 class with 6415.3 ha (92.5%), 6111.3 ha (88.11%) and 6111.3 ha (88.1%), respectively. Regarding the S3 class, three different crops (sesame, green pepper, and maize) were the most highly represented by 6151.8 ha (88.7%), 6126.3 ha (88.3%), and 6116.7 ha (88.2%), respectively. In the end, potato and beans occupied the highest areas in N class with 6916.9 ha (99.7%) and 6853.5 ha (98.8%), respectively. The results revealed that the integration of GIS and soil suitability system consists of an appropriate approach for the evaluation of suitable crop rotations for optimized land use planning and to prevent soil degradation. The study recommends using crop rotation, as it contributes to soil sustainability and the control of plant pests and diseases, where the succession of agricultural crops on a scientific basis aims at maintaining the balance of nutrients and fertilizers in the soil.

Abstract Aornakan I and Kuta Tinggi villages are villages located in Pak-pak Bharat Regency, North Sumatra Province. Currently, the villagers are planting Uncaria gambir and Coffea arabica. This study aimed to evaluate land for cofffe plantations on land overgrown with gambier in Pak-pak Bharat Regency. Sampling was carried out purposively on land overgrown with gambier plants in Aornakan I Village, Pargetteng-getteng Sengkut Sub-district and Kuta Tinggi Village, Salak Sub-district, Pakpak Bharat Regency. The evaluation of land suitability for coffee uses the matching method, namely by analysing laboratory data and data measured in the field with the characteristics of the land for cofffe. The results showed that the land evaluation for Coffea arabica was marginally suitable (S3) with the limiting factor was the root zone media (rc) in terms of soil texture.

Objective: Evaluate perinatal and neonatal outcomes comparing a water birth to regular childbirth in low-risk women. File and methods: Retrospective analysis of a set of childbirths that took place over a given period of time in the hospital and health center of Havířov. We compared a set of low-risk women that had given a water birth to a selected control group of low-risk women that had given regular childbirth. We evaluated statistical comparability, as well as perinatal and neonatal outcomes in both sets. Results: From 1. 1. 2020 to 28. 2. 2021, 1,083 women gave birth in the delivery department of Havířov hospital; from this set 122 were water births (11.3%). In our study, we only included 101 water deliveries (we designed our study to monitor low-risk births in order to be able to statistically correlate our fi ndings; 21 water deliveries were excluded from our study due to perinatal risk factors – gestational diabetes and induced deliveries). We selected 60 low-risk women for our control group. Both sets of women were compared and we ruled out any statistically signifi cant diff erences in age, education, body mass index, number of births given, gestation week at time of labor, number of smokers, premature rupture of membranes, women with previous history of one cesarean section, becoming pregnant by in vitro fertilization, presence of streptokoka skupiny B, and fetal weight. Water birth does not aff ect the Apgar score, neonatal adaptation to extra-uterine life, umbilical blood pH decrease, complications of infection, need of intensive care, and neonatal mortality. In the water birth set, we found increased occurrence of non-infectious conjunctivitis, treatable by regular eye drops without antibio tics. We have not observed the eff ect of water birth on duration of the fi rst and second stage of labor, total amount of uterotonics used, blood loss determined by the obstetrician, and uterine hypotonia. In the water birth group, we observed a prolonged third stage of delivery, lesser need for pharmacological stimulation (augmentation) of labor, notably lower use of analgesics, lower occurrence of birth injuries, shorter in-patient time, and more frequent bonding. Conclusions: We discovered that water birth does not increase the risk for mother and neonate in low-risk women. Despite initial concerns, our outcomes and mother satisfaction have clearly shown that water births are not only a temporary whim, but probably a new integral part of our obstetric care. Key words: water birth – analgesia with water – childbirth – perinatal and neonatal outcomes
