As a result of research conducted by the author, there were 120,200 hectares of areas identified in Polish cities that require regeneration, which constitutes a little more than 21% of all invested and urbanized areas. In terms of surface area and frequency of occurrence, the main problem is the one, which concerns old downtown districts. Drab prefabricated towerblock housing estates which, according to many municipal authorities are in a crisis, occupy a much smaller surface area of 14,000 hectares, yet the number of their residents approximates that of the old downtown districts and amounts to ca. 2.1 million people. The conducted research shows that there are 4.4 million people, who live presently in degraded areas and in areas that need to be regenerated. Also 24,000 hectares of post-industrial areas were identified. Other estimates indicate that there may even be twice as much of those post-industrial areas (40,000 hectares) but due to their contained nature and limited accessibility municipal authorities are not always aware of their existence. Based on the estimates of PKP S.A. Railways authorities one can assume that already today ca. 15,000 hectares of post-railway areas might be subjected to regeneration and reuse, including 100 multi-mode railway stations, which are critical for urban development. In 140 Polish cities and towns there were ca. 11,800 hectares of post-military areas identified, the majority of which have already been developed or adapted for urban purposes. Still there remain ca. 4,000 hectares of areas that require specific actions.

Water Use Efficiency and photosynthetic rate of Fallopia aubertii (L. Henry) Holub., Hedera helix L. and Vitis riparia Michx. grown in various exposures in two site variants: Warsaw city centre vs. suburbs wereanalysed. All studied climbers showed similar photosynthetic intensity in both sites. The strongest effect of the exposition was found for F. aubertii, followed by V. riparia, and shade tolerant H. helix. WUE of studied climbers was relatively low, higher in suburbs than in the centre, due to lower adaptation to different sites. TheWUE of the climbers depended on exposure and the highest scores were obtained for sunny southern and western walls, while the lowest in northern ones. Intrinsic water use efficiency of the studied climbers was higher in the city centre than in the suburbs.

In recent years, developing urban areas have affected food abundance and the feeding grounds of birds. The article contains analysis of the Tawny owl’s diet during four years (2006–2009) from different types of the urbanized area: city, town (much smaller than city) and countryside – based on 356 pellets with 726 prey items. The main group of victims was Rodentia, common were also Apodemus agrarius and Apodemus sylvaticus. Other important groups in the diet were: Microtidae (especially species Microtus arvalis) and Aves. As a generalist, Tawny owl fits the diet to the actual resources in a very flexible way. The main goal of the present work was to describe the food composition variability of the Tawny owl along with the degree of urbanization. Percentages of Microtus arvalis, Micromys minutus, Talpa europaea depended on the urbanization level, while Apodemus flavicollis, Insecta and Amphibia were related to the distance to nearest city centre. The study has shown that the diet of the Tawny owl has been changing along the urbanization gradient. It confirms earlier findings on high plasticity of foraging of this species in urbanized landscape.

Living conditions, place of residence and surrounding natural as well as atmospheric environment determine human health status and life expectancy. This article presents the specificity of biothermal conditions as illustrated by the selected cities in Poland, with a particular consideration of unfavourable thermal conditions due to excessively high or low air temperature. The present article is a review. In accordance with the tendencies of climate change, it was found that in the cities in Poland, conditions hazardous to health and life due to excessively high temperature and heat stress as well as very strong heat stress, occur with increasing frequency, particularly in the city centre. Additionally, thermal discomfort which is markedly present in the city centre is aggravated and moved to night-time due to urban heat island. According to numerous studies, the incidence of such situations is less frequent in the coastal zone and in the suburban zones.
