Main aim of this study was to assess the impact of different land uses on some soil properties, soil organic carbon (C) and total nitrogen (N) contents and stock capacities in Kastamonu, Turkey. Mature and young fir stands and adjacent pasture and agriculture sites were used to study the differences in some soil properties and soil organic C and N contents and stock capacities. Mineral soil samples were taken from two soil depths (the upper soil part 0-10 cm and the lower soil part 10-20 cm), and analysed for pH, texture, water holding capacity (WHC), salt, lime, organic matter (OM), P and K concentrations, total soil organic C and total N content, and stock capacities. Results showed that for the soil upper part, the agriculture site had the lowest clay, silt, WHC, pH, P, K and OM, whereas it had the highest sand content. Most of these soil factors were highest in the soil from mature fir stands. As for the lower soil part, there were no clear indications among the land-use types. However, the agriculture site had the highest clay, silt and soil pH, whereas the pasture site showed the lowest clay, silt, P and K contents. The mature and young fir stands always showed the highest mean soil C and N contents and stock capacities either at the upper or the lower soil parts, followed by the pasture and the agriculture sites. However, all soil depth was considered (0-20 cm), mean soil organic C stock capacity was highest for the pasture site (50.2 Mg C ha-1), followed by the young fir site (48.6 Mg C ha-1), the mature fir site (47.4 Mg C ha-1), and the agriculture site (32.3 Mg C ha-1). Mean soil total N stock capacity was highest for the young fir site (5.61 Mg N ha-1), followed by the pasture site (5.09 Mg N ha-1), the mature fir site (4.45 Mg N ha-1), and the agriculture site (3.33 Mg N ha 1).

More and more the external surfaces are beeing percived and designet as an integral part of the building. This skin, a protective mantle defines not only the interior but also the adjoining exterior space. It is visiting card of the building. Today's way of doing architecture should be a vision initiative which includes new ways of thinking about the relationship between construction and the environment, discovering new forms and content, and the assertion that the art of construction is in a new phase which will definitely change the way of our living, always in accordance with the language of nature. In this study we will show examples of how new forms of architectural design imitating nature completely change the old fashioned way of design. Especially Intelligent Façade which is a very efficient form of our impact in nature.

This area, however, will be particularly vulnerable to a predicted temperature increase and precipitation decrease, likely resulting in amplified drought extremes and episodes. Here we present a well-replicated composite tree-ring width chronology of millennial length from Albania, Balkan Peninsula. The Pinus heldreichii Christ dataset contains 302 series from 217 living and dead trees from 3 high-elevation sites, and spans the years 968-2008. Signal strength and growth-climate relationships were investigated using subsets according to location, age class, and growth level, as well as differently detrended chronology versions. Growth comparisons amongst the 3 sites' chronologies, between age classes and between growth-rate groups reveal an overall strong common signal. Growth-climate relationships over the last 100 yr, however, indicate that tree-ring formation does not depend on one single dominant factor, but rather on various combinations of summer precipitation and temperature resulting in temporally varying drought sensitivity. Our results emphasize a mixed and variable climate signal, corresponding with findings from other P. heldreichii sites across the Balkan Peninsula and Southern Italy.

The first regional survey was conducted in five countries: Albania, Bosnia and Herzegovina, Croatia, Macedonia and Serbia, under the scope of the FOPER project. The aim of the study was to identify the most frequent forest related conflicts in terms of types, conflicts attributes, actors, their attitudes and power relations, as well as to investigate more in-depth nature of conflicts and the way how they’ve been managed and how it influenced forest policy development. Materials and Methods: Analytical framework consisted of progressive triangle with three conflict attributes-substance (S), relation (R) and procedure (P) [13] embedded in four conceptsculture (CU), conflicts (CO), conflict management (CM) and policy development (PD) [12]. In total 840 semi-structured interviews were sent to decision makers resulted in response rate of 60%. Results were statistically analyzed by using metho...

The aim of the study was to identify the most pronounced forest related conflicts in south-eastern Europe (Albania, Bosnia and Herzegovina, Croatia, Macedonia and Serbia) at the policy and management levels in terms of types, conflicts dimensions, actors and their attitudes. Data were collected on policy level by semi-structured mail questionnaire with multiplechoice, ranking, and a few open-ended questions and on management level by face-to-face interviews in chosen case study areas. All collected data were assembled in a joint database consisting of 505 questionnaires and 111 interviews from case studies. Results revealed forestry related conflicts with significant differences between countries. The most often mentioned were: forestry vs. nature protection, forestry vs. wood processing industry, forestry vs. grazing and overgrazing, forestry vs. building a...

The high diversity of ecosystems and habitats offers rich habitats for a variety of plants and animals. This diversity is attributable to the country's geographic position as well as geological, hydrological, climatic, soil and relief characteristics. About 36% of the country's territory is covered by vegetation. There are still natural and semi-natural areas, where the degree of human intervention is almost absent or less sensitive. These areas, even preserve their true values of nature, both require special attention and care. For these reasons, Albania as part of the Balkan region as an area of global importance for biodiversit...

There are many thermal springs and wells. Their water has temperatures that reach values of up to 65.5°C. In the paper are presented the temperatures maps at deferent depth, geothermal map, heat flow density map, geothermal zones map and geothermal energy resources map etc. At present, the thermal waters of some springs and wells are used only for health purposes.
