At the end of 2006, I initiated research in a new domain, namely social aspects of nature conservation (human dimension – HD), concerning a wide definition of nature conservation. HD refers to research conducted using the methods taken from social sciences to investigate human attitudes and activities towards nature and determine how they can be applied in natural resource management. The decision to take up this topic, which was a novelty in Poland at that time, arose from my awareness of the need to transform the natural resource management system from a purely traditional system, based on the demand to protect particular elements of nature, into a more modern one that would include public participation and the development of rules to govern this participation in practice. I am particularly interested in the European ecological network Natura 2000, which differs from other national forms of nature conservation, thus causing human-nature conflicts. I pay much attention to the methods of management of these conflicts (e.g. through the participation of various social groups, socio-ecological consultation), social communication methods, as well as the study of attitudes to the environment both in children and adults. Apart from scientific research, I am involved in the popularisation of science and in educational activities, i.e. planning, conducting, and evaluating programmes and information or educational campaigns concerning nature conservation and municipal waste management intended for various types of audience (local governments, national park staff, directorate for environmental protection staff, teachers, school students etc.), and developing educational materials.
