The essence of the competitiveness of municipalities, regions and countries is, among others, proper space management, which should be carried out with the principles of multi-dimensional development policy. This development policy, which includes social, spatial, economic and environmental aspects, is a guarantee of development, which is characterized by a smart, innovative, sustainable and multifunctional development. Smart development is extremely important in the countryside, struggling with the growing problems not only connected with socio-economic but also environmental issue. A new, multifaceted model of socio-economic development is required in Central Europe's rural areas, shaped by a centrally planned economy, which have now become a training ground for intense transformation processes, and the choice of the right management strategy, definition of mission and vision guarantees competitiveness and prosperity. The aim of this paper is to analyze the spatial transformations of a selected rural municipality in Poland, in the context of the implementation of smart development. The rural municipality of Kleszczow, LAU 2 (Lodzkie Region, NUTS 2) is situated in the area, where the brown coal mine is located. The study focused on the spatial planning and analysis of the land reclamation, with particular emphasis on the creation of new and / or development of additional functions of the analysed municipality. According to the conducted research, the analysed area develops in a multidimensional way (for example: tourism, recreation and education). Implemented projects are also pro environmental, because they lead to the creation of new biologically active areas, the growth of biodiversity, and the development of the so-called "green energy".
