Soil degradation caused by erosion is one of the biggest environmental problems. The Geographic Information System (GIS) QGIS and ArcGIS were used to prepare thematic maps. The average slope resulted in smooth wavy (42.1%), flat (27.8%), and wavy to strong wavy (19.9%) over the entire length of the sub-basin. Erodibility resulted in very high (41%) mainly in sectors with a predominance of Neossolos Quartzarênicos soils, on average (7.1%) in the South and Southwest and low (51.1%) of the area corresponding to the soil of the type Dystrophic Yellow Latosol. The expansion of the agribusiness associated with inadequate soil management in areas susceptible to erosion at BHRG can compromise long-term environmental, social, and economic sustainability. It is important develop suitable agricultural techniques appropriate to the soil to optimize its use and its sustainable production capacity.

The watershed (catchment) approach provides a powerful conceptual model for quantitatively evaluating the structure, function and change within a landscape or region. The values and limitations of this approach are considered in this paper, with particular reference to the Hubbard Brook watershed–ecosystem model. The need for informed long-term (sustained) research is stressed; a haphazard collection of data is rarely valuable. Team-building efforts will be needed increasingly in the future to enhance the success of multidisciplinary teams tackling large and complex environmental problems.

In the article the author scientifically justified the choice of strategic directions of environmental activities in the region, which provide the formation of a real trend of gradual improvement of the environmental situation. The author uses a variety of methodological tools. The tools include methods of analysis, generalization, design, statistical methods. Aggravation of environmental problems requires regionalization of environmental policy, regulation and management of natural resources in the long term. Currently, the need to develop an effective strategy for environmental protection in the region is being actualized. Environmental consequences of economic activity arise and manifest themselves in a particular area. The local nature of anthropogenic impact on the processes of reproduction of natural resources and the state of the environment require the search for ways to effectively solve environmental problems, taking into account the characteristics of natural factors and conditions of the territory. It is necessary to analyze the specifics of the production and spatial structure of the regional production complex. The development of the environmental strategy provides for the definition of the environmental mission of the region and its ecological image of the future. When developing the strategy, priority environmental goals and objectives are selected. These tasks are then detailed in specific environmental programs. Further, the mechanism of their implementation is developed, the analysis and evaluation of the results and consequences of the implementation of programs are carried out. At the same time, the ecological mission of the region and its ecological image of the future are based on the analysis of internal and external factors that affect the formation of the ecological situation in the region. Further opportunities and threats for ensuring ecological safety of development of regional economy and habitat of people are revealed. The authors consider the regional environmental program as the main tool for planning, forecasting and practical implementation of regional environmental policy. The regional environmental programme facilitates the coordination of environmental activities in the region. Regional programs are developed within the framework of long-term forecasting and include strategic interests of Ukraine. The conditions of implementation of the environmental strategy in the region and the problems of creating economic tools to stimulate environmental protection measures, modern legal support of environmental policy are analyzed. The authors identify the features of financing environmental activities in Ukraine and explore innovative aspects of environmental safety of the national economy. The researchers revealed the place of the ecological subsystem in the structure of programs of socio-economic development of the region, analyzed the basic methodological and methodical bases of formation of the strategy of environmental protection in the region. The authors scientifically justified the choice of strategic directions of environmental activities in the region, which provide the formation of a real trend of gradual improvement of the environmental situation. The recommendations on improving the management mechanism of the regional ecological and economic system are substantiated.
