The circular economics of revitalization process of concentrated water runoff paths and retention reservoirs

Popis výsledku v původním jazyce

The problem of erosion and degrading soil in an agricultural landscape is very significant. It is most evident in the areas of the concentrated water runoff paths, particularly on the parts of the land blocks, where they are extremely exposed to the form of erosion furrows, through which the water flushes the arable topsoil from the surface. As an effective agri-environmental and climate defence tool, the grassing of these concentrated water runoff paths on arable soil. During this period of climate change, the intensity of heavy rains increases, which causes extreme erosion events. At the same time, it causes unacceptable soil loss from neighbouring land and burdens grassy tracks of concentrated water runoff paths with sediment. This reduces subsequent functionality of concentrated water runoff paths because of a violation of grassland compatibility. The absence of grass in these critical places during repeated torrential rains promotes erosion and subsequent degradation of the soil, as the water drains on it faster than on a properly grassed area. In order to achieve the desired functionality of the measure, for instance, the anti-erosion function, the grassland must be maintained at a reasonable condition, height, and must be above all continuously free from sediment deposits from previous erosion events. For this reason, it is necessary to remove colluvim and accumulated sediment from grassland after erosion events by revitalizing the grassland. Purpose: The main objective of the paper is to propose a solution to diversification of economic activities - production of different commodities, soil protection, sustainable management and by-products with possible economic effects. Part of the research is the product development from soil sediment, like organic matter demanded by agricultural operations for subsequent recultivation including related economic analysisi of the whole process). Methodology: Authors analyzed the Rural Development Program and related indicators from the period 2016-2020 and at the same time a literature review of selected demonstration objects. Authors also analyzed the procedure with selected techniques, technologies and agricultural mechanization. We found that no procedure has been yet established for this kind of revitalization, no technique or technology has been developer that would allow the required maintenance operations of these agri-environmental measures and landscape elements. Standard agricultural machinery and mechanization are not functional and suitable. It is necessary to address the problem, which will contribute to the development of the circular economy in this sector and the utilization of erosive sediment. Findings: With suitable machinery and appropriate technology, we would be able to remove the eroded sediment and then re-use it for next possible usage in agricultural sector. However, the current type of machinery that is available today is not apt to take on such a complex task of processing the colluvision taken from the concentrated water runoff paths and retention reservoirs.
