Published in: Origin of Relief of Central Poland and Its Anthropogenic Transformation in Łódź University Geographical Research, edited by. E.Kobojek, T.MarszałResults of a few decades of investigations on relief evolution of Central Poland in successive morphogenetic cycles were summed up in the monograph by K. Turkowska (2006) and visualised in the Geomorphological map of the Łódź region at a scale of 1:226 000 published in 2012. Recently, the aforementioned problems were widely discussed during the conference “Czynniki różnicowania rzeźby Niżu Polskiego” (Differentiation factors of the Polish Lowland relief) held in Uniejów in June 2012. Some current studies were presented in the anniversary issue of Acta Geographica Lodziensia (no. 100), which is a platform for the exchange of scientific ideas and opinions for 60 years
