This paper presents the assumptions and the preliminary results of the project entitled"Extension of the system for man-agement of post-mining areas in the Silesian province-OPI TPP 2.0".The overall objective of the project is to develop and implement a new e-service in the form of an open-access information system on post-mining areas in the Silesia Voivodeship.The range of information and tools planned to be made available is dedicated to assessing the possibilities and potential for economic and social reuse of these areas.The basic and extremely important stage of the project was to identify and collect data on post-industrial sites located in the Silesia Province.The information contained in this article illustrates the activities that were carried out in the initial phase of the project in which unmanned aerial vehicles(UAV)were used to identify and acquire information on brownfields(including post-mining sites)entered into the developed common database.The article assesses the possibility of using drones in an enterprise of such a large scale and also points out the advantages of using this method.The article describes the methodology and scope of work related to the acquisition of data that can be collected using unmanned aerial vehicle(UAV)covering surface infrastructure and land use of brownfields,allowing for the identification of negative phenomena on their site as well as monitoring of naturally occurring processes.Based on fieldworks experience and the results of numerous analyses carried out for different types of brownfields(e.***.post-mining areas,former transport bases,settling ponds,etc.),paper presents the advantages and benefits of drones(UAN)over other data sources used to monitor changes in an area.The article is based on the results of an inventory of over 600 brownfields located in Upper Silesia region(Silesia Voivodeship,Poland).

The world population will grow up to 9.8 billion by 2050.The intensification in urban growth will occur on all continents and in all sizes of cities,especially in developing countries,experiencing a greater rising in urban agglomerations of 300,000 to 500,000 people,those of 500,000 to 1 million and those of 1 to 5 million,by 2035.In this way,the demand of soil to host human activities(land take)will increase,mainly affecting soils with greater agricultural potential close to cities,at the same time as the need for food will increase.Land rehabilitation can contribute to human food security,to enhance ecosystem services and,if made by waste Technosols,those are viable as substrate for urban agroforestry systems.Although the references for brownfield reclamation for urban agriculture,adding constructed Technosols and de-sealed soils can recover its ecosystem functions even food supply services and would be the solution in urban areas.
