The purpose of the control is to realize an orderly land use, so that the function of space in an area is in accordance with the planning done by the government, especially local government. Batu city development which has been very rapid, it is known that the conversion of agricultural land in Batu City continues to increase. As mentioned above, Batu City Government has made various efforts to implement controls to maintain food security and maintaining agricultural land is relatively limited given the urgency of the general plan and detailed plans, that the consideration of the importance of regional spatial dimension is the key issue in regional development, especially in addressing the issue of land use conversion.

The development of urbanisation is linked to qualitative and quantitative changes in the landscape and its components aimed at strengthening economic, administrative and cultural-social functions, which are associated with ever-increasing pressures on ecosystems and their individual components. These pressures are subject to various factors—socio-economic, political, environ-mental, etc. In this paper, we present an evaluation of the environmental impacts of the development of urbanisation in Slovakia. Independent Slovakia belongs to the young European states. The communist period lasted from 1948 to 1989. The character of landscape, the quality of the environment and also the degree of anthropisation of territory were dependent on a centrally managed economy. Urbanisation changes began to manifest themselves rapidly after 2000, when the economy was transformed and Slovakia was preparing to join the European Union (Slovakia joined the European Union in 2004). The transformation from central planning into a market economy was the basis of the changes, which was conditioned following strong pressure of investors on the landscape, the construction of technological parks, shopping and logistics centres and transport infrastructure and the construction of residential complexes. According to the European Environment Agency’s study on urban sprawl between the mid-1950s and the end of the 1990s, industry, commercial and transport services have grown at a significant rate and the residential areas at a moderate rate in Slovakia. On the other hand, Slovakia has areas where urbanisation has the opposite trend. Rural settlements are abandoned as well as large areas of agricultural land. The character of land use has fundamentally changed over the past 20 years. These changes not only have a spatial dimension but are associated with the emergence of various environmental problems. The paper deals with the impacts of anthropisation and industrialisation of Slovakia after 2000. The anthropisation process in Slovakia was determined through data processed in GIS and also through the statistical data representing land use. Based on the ecological significance of land use elements, the degree of anthropisation in Slovakiawas calculated.

In the Kaliningrad region there are about 70 % of all polder lands in Russia. On these lands with high potential fertility, it is advisable to intensive agriculture. The area for the average moisture year is an area with excessive moisture, which indicates the need to maintain the rate of drainage on agricultural land. Many different factors play a role in ensuring the drainage rate, one of which is pumping stations and pumping equipment installed on them. An important parameter in the use of pump-power equipment is energy consumption, since in this industry it is a considerable expense item. Improving the energy efficiency of pumping stations on polders is a pressing issue today. At the majority of polder pumping stations, domestic power pumping equipment is installed with excess power and head of 4–8 meters, and a new one is selected based on the maximum possible head in a given place. In the Kaliningrad region, the energy efficiency of polder pumping equipment has never been analyzed. In this paper, a statistical processing of the geodesic pressure of water at the polder pumping stations of the Slavsk region for 2000–2002 was carried out. On the basis of these data and data on the hydraulic characteristics of pressure pipelines, the calculated water pressures were determined for the rational selection of pumping equipment. The calculation of the economic efficiency of pumps with optimal power compared with pumps of excess capacity. The results of the study can serve as a justification for the transition to the pumping equipment with less power and pressure, which will lead to a decrease in the cost of money for electricity.

Global climatic changes, technogenic pollution by pollutants, violations of technologies of exploitation of reclaimed land lead to a decrease in fertility and soil degradation of agricultural land. Adverse weather conditions, resulting in a lack of adequate flood water, and economic difficulties in agriculture make it difficult to fill the deficit of organic matter and macronutrients in reclaimed alluvial soils. The monitoring of agrochemical properties of alluvial meadow medium-loamy soil of the stationary site (reclaimed lands of JSC «Moskovskoye» of Ryazan region), located in the floodplain of the Oka river, conducted by the Meshchersky branch of Vniigim, showed the presence and intensification of degradation changes in the soil. Thus, comparing the agrochemical indicators in the layer 0–20 cm, carried out in 1995, with the indicators of 2019, it should be noted a decrease in soil fertility. The decrease in soil quality was expressed in a decrease in the amount of mobile phosphorus by 37.6 %, mobile potassium by 53.3 %. Also, during this time there was a decrease in organic matter by 9.1 %, and an increase in soil acidity was 0.6 pH. As a result of such changes, soils lose ecological stability and become more vulnerable to adverse weather and negative anthropogenic impacts. In such a situation, advanced agricultural techniques should be actively used to obtain guaranteed, environmentally safe crop yields and restore the fertility of degraded reclaimed soils. In this regard, there is a need to develop innovative methods of fertility restoration of degraded alluvial soils in reclaimed lands using multi-component organic-mineral ameliorants. Meshchersky branch performs research work in addressing this issue.
