Abstract
The innovative method of assessment of the motorway impact on agricultural land presented in this study allows to estimate all losses related to the directions of this impact. The basis for the determination of losses is the analysis of land use variability and bonitation classes as well as the location of access roads to the land along the axis of the planned motorway. The applied measure of the motorway's impact on agricultural land is the change in land value, at which determination only the diversity of its suitability for agricultural production is taken into account. The developed method of determining the impact of the motorway on agricultural land was presented on the example of the A4 motorway section between the villages Jasień and Bobrowniki Małe. The existing motorway section was evaluated and then the obtained data were compared with the results obtained for the alternative version of the motorway running on the same section.
Highlights
The simplified method of assessing the motorway's impact on agricultural land was used to conduct the research in this article
To carry out the analysis properly, additional information is needed on the variability of soil quality on the motorway route, the location of roads and motorway overpasses, areas of agricultural land for which access is associated with crossing the motorway lane and parameters of the lay-out of plots cut by the motorway
The simplified method of motorway impact assessment presented in this study takes into account all the most important directions of the motorway's impact on agricultural land and presents this impact in measurable and com-parable units
Summary
The simplified method of assessing the motorway's impact on agricultural land was used to conduct the research in this article This method is useful during initial motorway route design [2]. This method takes into account only the general assumptions concerning the motorway parameters: the axis of the motorway, the width of the road and the occurrence of protective green belts. The loss of land taken over for the construction of a road lane, decrease in the production capacity of land located near the motorway, deterioration in the number of farms cut by the motorway axis The value of these plots is the measure of the multidirectional impact of the motorway, at which determination only their production usefulness was taken into account. The calculation procedure related to the motorway impact determination has been automated using the developed computer program, which facilitates its application [3]
