In the last years the agricultural areas in Poland have been under great alterations caused by external production requirements. The food demand and farm products. prices decreased which became an important turn in comparison with the previous political period of almost unrestricted demand and high prices for farm products. That phase, very beneficial for farms. development had negative impact on ecosystem, which nowadays may be observed in environment. Among others they caused water eutrophisation and decrease of landscape values. Changes in prices and demand for products also influenced the socio-economic situation. The food overproduction and in consequence the decrease of farmers. income and employment or later on an exclusion of vast areas from agricultural production may be observed in the whole country. The situation caused the need for employment of the surplus of the human sources and new management of all agricultural land. It is the alternative crops that create the greatest opportunities for implementation of these free sources. They enable a faster flow of financial funds compared to, for example forestation; moreover they can be a source of new products for local industry development. Those features are attributed to poplar plants, planted since long by farmers in Italy, France, Belgium and Great Britain. The aim of this research is to localise, with the use of GIS tools, the potential areas for such plants. The assumptions are obligatory within the European PAMUCEAF Programme and are associated with the localisation of potential plantations on the agricultural grounds and with the requirements of rules in sustainable development. Environmental data of geomorphological, climatological, soil and hydrological information were processed into environmental characteristics that became compared with the poplars. requirements in terms of water supply, soil conditions, drought resistance, risk of frost etc. It was also arranged the information of the location of population, works and so, for delimitation of the areas where poplars could be implemented in varied strength and associated with the environmental, economical and sociological restrictions. The first stage of the research eliminated the areas improper for poplars. planting. The second one excluded the forest and designated areas from those of eligible environmental conditions. In the third stage the key areas for suggested poplar plantations were delimitated. Further on, they were divided into separates, in which the economical and social issues e.g. the lack of local market separated from the development centres or high unemployment rate, became recognised as the main aspects of introducing poplars. The main results of the research are the maps of Poland presenting the areas with the most appropriate physical conditions for poplar plantations. These are the areas in northeast part of the country as well as in the south central ones. The advantages water conditions as well as relatively low frost pisk were the most important factors that decided of the delimitation. In some areas, mostly in northern part, the frost resistant clones should be considered the Polish research conducted since the 70. indicated either the native or northamerican ones. The suggestions associated with the implementation of crops in terms of socio-economical requirements reveal that wood as well as agricultural landscape improvement effects could be gained in the areas close to big city areas as well as in the villages with a high social potential rate.
