Abstract. Intensive agricultural land use across Europe has altered nitrogen (N) budget of catchments substantially, causing widespread N pollution of freshwater. Although the N cycle in forests has changed due to increased N deposition, most forest soil waters in Europe have low nitrate concentrations. The protective function of forests on water quality has led to increasing interest in the planting of new forests on arable land as a measure to protect valuable or sensitive freshwater resources. The paper illustrates the effects of afforestation on water and N cycling using the Integrated Nitrogen Catchment (INCA) model. The model was calibrated on the Horndrup catchment in the eastern part of Jutland, Denmark, which is dominated by agricultural land use but also covered by 18% of forest land. The dynamics of nitrate concentrations in the stream water were simulated successfully by INCA over a three-year period. The simulation of the dynamics of nitrate concentrations in the soil water is closely linked to the simulation of the hydrological dynamics and especially to the rainfall. The best fit was achieved for both arable and forest land during the wettest year of the study period. The model was then used to simulate the effect of afforestation of a catchment dominated by agriculture on N fluxes with seepage and runoff. Scenarios of whole catchment conversion to forest were run, based on observations of evapotranspiration and N deposition from other Danish sites. The simulated conversion to mature forest reduced runoff by 30–45% and reduced the nitrate concentrations in the soil water by 50–70%. The simulated effect of afforestation on N leaching was an almost direct reflection of the change in the N input: substantial changes in the plant demand and soil N dynamics over the afforestation period were not simulated. To simulate the N dynamics over longer time-scales, appropriate for the study of afforestation, it is suggested that the INCA model be run with transient scenarios and linked to more detailed plant and soil models.

We examined the use of stream baseflow water quality as a representative measure of mean ground water quality in the Tomorrow-Waupaca Watershed in central Wisconsin and the relationship between agricultural land use and watershed water quality. From 1997 to 1999, 38 stream sites were sampled for nitrate during winter and summer baseflow conditions. Some sites have been sampled during winter baseflow conditions since 1994. The land area contributing ground water to each stream sampling site was delineated, resulting in 38 sub-basins. In addition, over 3500 test results from private wells in the watershed were compiled and mapped using a Geographic Information System (GIS). Nitrate concentrations in stream baseflow and well waters were found to have strong positive correlation in the sub-basins of second order or higher. This indicates that stream baseflow may be valid for monitoring mean ground water quality in watersheds predominantly fed by ground water, where much of the stream nitrate is believed to originate from ground water. Analysis of seasonal variation in the stream data showed that winter nitrate concentrations were higher than summer concentrations, implying that winter stream monitoring may be more critical for the assessment of overall ground water quality in the watershed. We also found that, as the amount of agricultural land increased in each sub-basin, average nitrate concentrations in the well and stream waters also increased, suggesting a connection between agricultural land use and nitrate contamination of water resources in the watershed.

The aim of the work was the landscape analysis of agricultural geographical landscapes in the Altai Territory and elaboration of measures aimed at the rational use of agricultural lands. Environmental and landscape (landscape) approach became the main method of scientific research used in the analysis of modern agricultural landscapes. The cartographic method, using GIS-technologies, made it possible to digitize the obtained materials. Synthesized maps of agro-ecological, natural and other zoning of territories are based on topographic, soil, geobotanical and other thematic maps made during land surveying during the field survey. Retrospective analysis, induction and deduction methods,analysis and synthesis, as well as the abstract-logic method were also used in the work. Our main result was the analysis of land use territory for agricultural enterprise in municipal district of Altai Krai. Exploration of lands indicates a pronounced plant-growing specialization of JSC “Pobeda” with a developed animal breeding direction. Limiting factors affecting the rational use of land are natural and climatic conditions, terrain,unsystematic anthropogenic activity and, as a result, the development of erosion processes. The degree of eroded and deflated arable land is more than 50%, hay and pasture lands are also very unstable. Landscapes have been typified, based on which eleven types of land have been identified and their geomorphological description has been carried out. The first five types of land can be used for agricultural production with limitations compensated by crop technology and erosion control measures, the sixth and seventh types require grassing and, in some cases,conservation, the eighth and ninth types can be partially used for pasture and area valorization; the remaining two are not suitable for agricultural use but should be potentially used for planting and forest management. As a result of the presented transformation of agricultural lands, the structure of cultivated areas has changed. The area of arable land decreased by 877 ha, and of pastures by 365 ha,while the area under hayfields, fallow lands, and forest lands increased by 295, 191, and 875 ha respectively. Low-productive lands were withdrawn from agriculture. We suggested that the sustainability of agricultural land use was mainly caused by the reduction of anthropogenic load and increase in ecological equilibrium of the territory.

The Impact

This study examines the impact of agricultural land use change into a petroleum mining area to farmers’ socioeconomic conditions around petroleum mining project area in Gayam District of Kabupaten Bojonegoro. The analyses used a mix method, using both quantitative and qualitative approaches. The quantitative approach is used to determine the impact of agricultural land use change on the social and economic aspects with the respondent farmers were supported with a scoring method to determine the condition of socioeconomic vulnerability of farmers, while the qualitative approach carried out through in-depth interviews to some informants who have been affected by the project. The results shows that the presence of the petroleum mining industry has not had a positive impact yet on the farmers’ socioeconomic conditions. By the 700 hectares of agricultural land conversion, the agricultural production capacity of the area tends to decrease, including by the decreasing of the productivity of some agricultural land in a radius of 500 m from the fenceof the mining area as they are affected by the fence’s spotlight. The farmers' income also tends to decrease because of the decreasing of their working hours as the big loss of agricultural land in the area. As a result, many farmers should work outside of the area to search replacement of the arable land. These situations lead to a moderate condition of social and economic vulnerability for the farmers, especially for those who still have sufficient assets to meet the needs of their economic.

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.

Cultivation Practice

Due to low groundwater recharge rates and intensive agricultural land use, elevated nitrate concentrations in groundwater are measured in Lower Franconia, Bavaria (Germany). Analysis of cultivation practice in this region showed that crops with high nitrogen-surplus were cultivated to a significant extent. By the example of a catchment area where drinking water is extracted, an approach for a change in agricultural land use was tested. Fields were classified according to soil quality and the type of sub-soil. Measures like conversion of arable land into grassland or changes in type of crop that is grown, were adjusted to the local (field) conditions. Thus nitrogen surplus could be reduced to half by the extensification of one third of the agricultural land. Due to the classification system, the measures are realised in the most cost-effective way as well.

The article is devoted to the formation of the institutional environment of ecologically safe agricultural land use through the model of harmonization of ecological and economic interests of the subjects of agricultural land use. The structure of agricultural land use is based on criteria, the content of which represents both economic and environmental interests of society. For example, the landowner (land user) is interested in converting his land into the most economically attractive - arable land, which reflects his private economic interests, and on the other - society is interested in maintaining the optimal state of agricultural landscapes, which in turn provides the optimal ratio of destabilizing, stabilizing and stabilizing reflecting the public environmental interests [7]. Usually such differentiation of interests of subjects of agrarian land use causes situations of impossibility to agree them voluntarily. Therefore, there is an urgent problem in effective regulatory policy in the field of land use, in particular through the formation of the institutional environment of environmentally friendly agricultural land use through the model of harmonization of environmental and economic interests of agricultural land users. In the article, it is clarified that the institutional model of harmonization of ecological and economic interests of subjects of agrarian land use provides for the introduction of tools to eliminate the conflict of ecological and economic interests, which includes a number of tools, levers and techniques, in particular: -adaptation paradigm; formation of ecological consciousness of land users, ecological morality and ethics; development of the organizational and economic mechanism of formation of ecologically safe agrarian land tenures and land uses optimum through a combination of market and state levers of influence; regulatory and legal support of ecological safety of agricultural land use; optimization of the organizational structure of land use management. Keywords. Institutional environment, institutions, ecologically safe agricultural land use, land relations, economic development, ecology.
