At present, it is a trend to show these unique features by emphasizing local traditions or recreating historical ones that are often forgotten a long time ago. Return to the former land use forms means the need for changes deliberately made and stimulated by regional policy. Regional policy means in that case both consent to the allocation of land for vine plantations, as well as the involvement of resources for assistance in these projects. Our analysis of historical documents indicated that the cities such as Zielona Góra, Gubin, Krosno, Sulechów and Świebodzin were in the past known European viticulture centres. In the past only in Zielona Gora locality thousands of hectares were designated to wine production. For the whole region, it was many times larger. The contemporary land use form described in the paper is strongly supported by the Marshal's Office of the Lubusz Voivodship (regional authority) as local ones (district offices, commune offices, local councils) as well. The area of vine plantations is growing year by year. The policy of the region supports its further growth. Up to date, following the strengthening the position of regions in Europe, their wine-making history is recognized, new production vineyards are created, and campaigns are launched to encourage vineyards and tasting local wines visits. Our study of regional economic trends revealed that oenological tourism has perceived as an important element of the economic development of historical wine-making regions and former vineyards. Museums, thematic parks, tourist routes and even wine spa are established. These activities are perfectly fit with agricultural tourism, creating an important group of the wine tourism and support interesting, individual forms and characteristics of regional culture. Based on the experiences of the Lubusz voivodship (Poland) a conceptual framework [...]

Engineering students are educated to act as initiators and performers of activities that change space. The purpose of this study is to answer question regarding how the engineering students recognize problems related to shaping the landscape. In the years 2012–2015, surveys were conducted in a group of 274 students of the University in their final year of environmental engineering and civil engineering studies, in order to find the main characteristics related to the problem. Students tended to assess the landscape in a manner determined by their education in natural science—emphasizing the division between the well-shaped natural landscape and the malformed anthropogenic one. There were differences between the groups of students—civil engineering students noticed the qualities of architectural objects and shaped green...

It is also problematic because of the necessity to manage the ash that is generated in the process. The combustion of biomass pellets is optimum when their moisture is 6–8%. The calorific value of pellets made from straw and willow wood (4:1) was 17.3–20.1 MJ∙kg−1. There were serious problems with burning this material caused by the accumulation and melting of bottom ash on the grate, which damaged the furnace. These problems with optimizing the biomass combustion process resulted in increased CO emissions into the atmosphere. It was shown that pelletization could also be used to consolidate the ash generated during the combustion process, which would eliminate secondary dust during transport to the utilization site. For this purpose, it was suggested to add binding substances such as bentonite and bran. The analysis showed that an optimum material for pelletization should contain, on average, 880 g of ash, 120 g of bentonite, 108 g o...

The combustion of biomass poses the problem of the use of ash produced in the process. There are fluctuations in the properties of energetic biomass, which results in high variability of ash obtained by combustion, especially in terms of specific conductivity (EC) (8.1–9.7 mS·cm−1), the total content of components and their bioavailability. The combustion of biomass leads to large fluctuations in the total content of carbon in the ash (13.6%–28.6%). In this way, waste material with very different biological properties and cation exchange capacity is obtained. Ash from the combustion of biomass is an alkalizing material, rich in Ca, K and Mg carbonates (4.5%). The high average bioavailability of Pb (87.4%), Cd (63.1%) and Zn (46.9%) present in the ash is an environmental problem. The mobility of these heavy metals was reduced by half by the addition of bentonite during ...

Because of social resistance to burning crop plants, mixtures and pellets made from or including waste materials are a good alternative. The mixtures analyzed, prepared from wood and municipal waste, were characterized for their calorific values, 7.4–18.2 MJ·kg−1. A result, over 15 MJ·kg−1 was obtained for 47% of the quantities of mixtures being composed. It has been demonstrated that wood shavings and sewage sludge have a stabilizing effect on the durability of pellets. The emissions of acidic anhydrides into the atmosphere from the combustion of pellets from waste biomass were lower for NO, NO2, NOx and H2S than emissions from the combustion of willow pellets. Obtained emission results suggest the need to further optimize the combustion process parameters.

The history of Zielona Góra as an urban area began probably in the 13th century. By the end of the 18th century, it was a typical small town (8 000 inhabitants), based on agriculture and craft. Intensive industrialization processes took place in the 19th and early 20th century. The main factories in the city were connected with food processing, textiles and metal industry. The present state of urban soils is a result of di§erent human activities: agricultural, urban and industrial.
