Estimation of the influence of motorway construction on the changes of agricultural land usefulness was carried out using simplified method elaborated by the author. It is based on the analysis of the course of the motorway axis and on the use of essential parameters such as width of the total land requirement, plots layout, or the arrangement of the roads and viaducts. Also other features of the land were taken into consideration. They inform about the agricultural usefulness of the land and may be used by determination of consequences of such investment realisation. Analysis was performed on a road section in the vicinity of Łódź. The road runs across seven villages in two communes - Stryków and Nowosolna. The sec-tion length is equal 7.145 km. The road section under consideration is divided in two parts depending on the commune in which is situated. The motorway runs for the most part through the arable land of the average class. It crosses 21 roads. 5 of them will be equipped with viaducts. The average distance between roads will be increased four times. Profit-making value will be reduced on the area of 300.92 hectars. ...
An innovative method developed for estimating the highway impact on agricultural land allows determining all losses associated with the directions of this interaction. The basis for determining losses is the analysis of variability of land use and quality classes and the deployment of access roads to the land along the axis of the planned highway. Adopted measure of the multidirection impact of the highway on agricultural land is a specified amount of change in the value of land, at which determination only the diversity of the land suitability for agricultural production is taken into account. The developed method for estimating the highway impact on agricultural land is presented on the example of the designed section of the A4 motorway between Rzeszow and Tarnow with about 79 km of length. These are the areas located in the Podkarpackie Voivodship. The construction of one kilometer of the analysed section of the highway will cause the reduction of the agricultural land value amounting on average about 1,500 of cereal units. Taking land for the highway construction and its negative impact covers about 70% of the total loss of value of agricultural land. The remaining 30% loss of value of the land is associated ...
