The assessment materials of pollution features of agro-ecosystems of Ukrainian Polissya in the remote period after the accident are described in the article. It is shown that the main factors of influence on the flow of 137Cs from soil of contaminated agricultural land during a distant period do not differ from the previous period factors. It was found that current levels of 137Cs specific activity in soils of agrocenosis almost two and more times less than in the natural plant phytocenosis. The depth of massive infiltration of 137Cs in soils of arable land is much greater than in virgin soils, and almost completely determined by the process of root transfer and working capacity of the reservoir, which varies in the area of research from 10 cm to 30 cm. Despite the significant pollution of soil, the level of contamination of agricultural production is relatively low and does not exceed the permissible levels of radionuclides (DR-2006). Thus the highest rate of 137Cs transfer is noticed from soil to products of natural lands (0.06–0.66) and depends n the season and type of land.

The quality and safety of beekeeping products depends primarily on the ecological condition of natural nectar-pollinating lands. It is known that nectar-pollinating lands after the accident at the Chernobyl nuclear power plant were radioactively contaminated, which led to the accumulation of radionuclides in nectar, as well as in the product of its processing by bees - copper, in some cases above acceptable levels of cesium-137 16 nKi / kg (TAL - 91). This level of cesium-137 concentration was characteristic of honey produced by bees directly in the conditions of the northern Polissya of Ukraine within the Narodytsky, Ovruchsky and Polissya districts of the Zhytomyr region. In these areas of nectar-pollinating lands, in soils of which the specific activity of cesium-137 ranged from 1 Ki / km2 to 5 Ki / km2, levels were observed in honey that exceeded TAL - 91. It has been proved that the migration of cesium-137 into honey depends on the level of contamination of honey lands and the botanical origin of honey plants. The lowest content of radiocaesium immediately after the Chernobyl accident was found in dandelion and linden honey, and the highest - from legumes and honeysuckle of forest plantations, such as buckthorn, raspberry, ivan tea. A relatively high content of radiocaesium was found in honey produced by bees from thyme and heather, even in areas where the content of cesium-137 was higher than 1 Ki / km2. As a result of the research, it was found that the production of honey from winter oilseed rape and sunflower in terms of nectar-pollinating agricultural land returned to agricultural production after 34 years after the Chernobyl accident with a specific activity of cesium-137 in soil up to 2.47 Ki / km2 is safe. The specific activity of cesium-137 in such pollution was lower than TAL-2006 in honey produced by bees from winter rape and sunflower, respectively 11 times and 8.2 times. In honey produced by bees from the nectar of winter rape, there was a lower concentration of cesium-137 in 1.14 times compared to sunflower honey.

The article is devoted to substantiating the prospects for increasing the marginal volumes of agricultural production for export in the next four years. Two scenarios of such production are considered: 1) expansion and 2) intensification of the use of land resources. As part of the development of the first scenario, an analysis of the distribution of unused agricultural land, including arable land, by federal districts was carried out. Also, based on the forecast of the introduction of additional annual volumes of acreage in the subjects of the Federation, the calculation of additional volumes of agricultural production, which can be expected in the next four years, was carried out. The analysis of data on the increase in the yield of export-oriented crops over the past five years has been carried out, in the framework of the second scenario, the calculation of the projected additional yield due to the intensification of agriculture is presented. The results of the study indicate that the intensification of agriculture will have the greatest impact on the growth of production and export of agricultural products in the near future.

The paper analyses relationship between pine (Pinus sylvestris L.) biomass and the specific activity of an artificial radio‐isotope 137Cs in wood. The specific activity of 137Cs was measured in the segments of pine (Pinus sylvestris L.) annual rings. The biomass of segments and the density of wood were estimated experimentally. It is determined that relationship between pine (Pinus sylvestris L.) biomass and pine age is not linear. In the variation of biomass are time when biomass grows slowly (25–55 pine age or 1959–1990 m. period). The specific activity of 137Cs in pine annual rings depends on the rapidity of biomass growth. The specific activity of 137Cs varied from 0,3 ± 0,1 to 13,4 ± 2,7 Bq/kg when the biomass grew rapidly and its average value was 4,3±1,1 Bq/kg. When the biomass grew slowly, the specific activity of 137Cs varied from 1,8 ± 0,7 to 20,6 ± 5,3 Bq/kg, and its average value was 9,6 ± 2,6 Bq/kg. Global pollution after nuclear explosions, pollution after the Chernobyl Nuclear Power Plant accident and uptake of 137Cs from roots had an influence on the specific activity of 137Cs in pine annual rings.

Main Factors

Agricultural production in the Caribbean is being threatened by many factors such as decreasing availability of arable land, climate change effects such as increased incidences of flooding and drought, labour shortages, and competition from importers. However, one of the most important threats to agricultural production is the often under-recognised and under-reported area of farm theft (referred to as praedial larceny in the Caribbean). It involves the theft of agricultural produce (crops, livestock and fisheries) and farm equipment. One of the main reasons why this threat is so important is that theft of this type is very hard to prove. If indeed perpetrators are caught, and prosecuted successfully, the penalty is practically negligible. This paper examines the current status of farm theft in the Caribbean region, explores some of the main factors influencing farm theft, reviews some of the strategies attempted in the Caribbean and other places around the world and makes several suggestions to create a more secure food region. While the discussion calls on food producers to take several best practice actions to mitigate losses to praedial larceny, it emphasises that the primary responsibility is with government-led actions in the areas of modernised policies, updated laws and enhanced enforcement efforts.

The Impact

The subject of the study presented in this article is the economic relations arising due to the progress of the urbanization that leads to changes in agricultural production. For a long time in Russia a reduction of agricultural land, arable land and crops takes place. One reason for this is the global progress of urbanization. Changes in agricultural land use occur across the country however this process is uneven in different regions. Among all regions Moscow and Moscow region significantly stand out. The study showed that in the more urbanized regions of the country reduction of the agricultural land and changes in agricultural land use are greater than in less urbanized ones.

The paper studies the issue of the use of disposed agricultural land through the example of LLC “Alliance-agro in Sengileevsky district of the Ulyanovsk region. The authors consider the grounds for cultural and technical work and provide the results of a survey of unused arable land on the farm. A technology for the development of disposed agricultural land is proposed. Everyone knows that agricultural land is of particular importance as a means of agricultural production and is the second largest category of land in the unified land fund of the Russian Federation in terms of area, which includes the best and fertile lands making up the heritage of the country. Despite the fact that the schemes for the use of agricultural land are developed, many questions of a theoretical, methodological and applied nature need to be improved, since this is associated with incessant changes in the legal and organizational systems of land use. As a result of irrational use of land, degradation, littering, overgrowing with trees and shrubs of agricultural areas occurs. These processes lead to the fact that fertile lands are withdrawn from circulation. Our research is aimed to solve the problems in the field of the improvement of the cadastral registration of lands, the process of the organization of rational land use, as well as the most effective use of unused lands overgrown with trees and shrubs. The solution to this problem will help the rational transformation of the agricultural land use system and increase in their efficiency. Moreover it will help to solve the problem of the involvement of unused land in agricultural production and increase the efficiency of cadastral registration of agricultural land. As a result of the land clearing proposed by the authors, the sites of this object will be put into agricultural circulation, where any zoned agricultural crop can be grown from the first year of development in case of a favorable water-air regime in the root layer and complex agrochemical cultivation.

The Impact

The features of formation radiation situation in agricultural production in the areas contaminated by the Chernobyl accident were considered. On the basis of the summarized post-accident experience, assessment was made of the effectiveness of countermeasures to reduce the level of radioactive contamination of agricultural products. The current problems and scientific challenges to support agricultural production in the area of radioactive contamination in the remote period after the accident were formulated. It is shown that the use of modern technology and employing profitable agricultural production is the best way of rehabilitation contaminated areas. Natural processes of rehabilitation will not help to normalize the radiation situation theretore carrying out countermeasures in contaminated areas is vital. The developed technologies are the most effective which make it possible to carry out targeted countermeasures in individual households and small arrays. Monitoring the distribution of radioactive pollution, behavior of radionuclides in the related environment and forecast of their migration allows developing and implementing the most reasonable management decisions to improve the radioecological situation.

The main purpose of the article is to assess the share of agriculture in the national economy of Russia and the designation of the main factors determining the development of agriculture in this country. The importance of agriculture in the Russian economy is relatively small, which is a characteristic feature of developed economies (about 4% of GDP). However, agriculture represents a significant share in the structure of the employed – 9.2%. The use of agriculture as a food self-sufficiency has become essential after imposing embargo on imported products. Russia as a country has a large area of land. The surface of the used agricultural land after the fall in the 90s has stabilised at the level of 800 thous. km2. At the same time intensified agricultural production has resulted in increase of performance and larger crops. A significant potential of the land, as well as a progressive technological movement is an opportunity for the development of agriculture in Russia.

Effects Of Land Use

The study analyzes the possibilities of using cost estimates of ecosystem services to assess the effects of transformations in land use. The consequences of transformations were assessed by comparing the value of basic ecosystem services for different patterns of the land use structure, taking into account the fact that the volume of ecosystem services provided is limited by the ecosystem sustainability limits. To estimate ecosystem services, the methodology developed by the author was used. It is based on the indicators of agricultural land productivity and their value terms. The assessment was carried out for the Zarinsky district of Altai Krai, located at the junction of the West Siberian and Altai-Sayan physicogeographical countries. The study has revealed that the greatest value of basic ecosystem services in the region with agricultural specialization can be achieved by optimizing the agricultural load – reducing the share of arable land and increasing the share of forage land in the total area. It is proposed to implement this by involving plots of fallow lands in circulation: some of the plots are proposed to be used for reforestation, while others – for haying and grazing. This will balance the need to maximize agricultural production, while not reducing the sustainability of the ecosystems.

Study Objective

Agricultural land is an important natural resource and forms the basis for food production. Global and local socio-economic and environmental changes are often the driving forces of changes in land cover and land use. Land abandonment in rural areas is one of the processes observed in Europe today and usually leads to increased afforestation. The intensity of this process in Central Europe is linked to the political and economic changes that took place at the end of the 20th century. The study objective was to identify the natural and socio-economic factors of this process in Lublin Province—a major region of agricultural production in Poland. From 1990 to 2018, over 130,000 ha were excluded from agricultural use, which represents 7% of the arable land in 1990. Land abandonment showed considerable spatial differences when comparing different counties: its magnitude ranged from 4% to 13% of the county area. At the same time, due to the specific type of land use in the province (small farm holdings divided into several fields), the intensity of land abandonment was underestimated when based on overview data (CORINE). It was observed that the intensity of this process was correlated with the natural conditions (topography, soils) for agricultural production and the socio-economic characteristics (area of arable land, forest cover changes, farm size) of the counties as well as the absorption of Common Agricultural Policy funds.
