The degradation of aquatic habitats has increasingly become one of the most important factors influencing the distribution of freshwater species worldwide. We analysed the occurrence of three crayfish species, Astacus astacus, Austropotamobius torrentium and Orconectes limosus, in relation to habitat degradation status (based on Directive 2000/60/ES), stream morphology, geographical characteristics and land cover. In total, we analysed 6,768 sites within the Czech Republic (Central Europe), of which 6,187 sites lacked crayfish; among the remainder, A. astacus was present in 507 sites, O.

In view of creating in 2015 the Europe Asia economic union (EAEU) and its possible future expansion, there are considered issues of correlation in national and collective food security under conditions of countries integration, as well as basic lines of ensuring such security. The models of agrarian policy in EU and EAEU are compared, stressing that the EAEU statute document envisages the agreed (coordinated), but not uniform agrarian policy. That is the principal difference from EU agrarian policy, which contains uniform economic rules.

This paper assesses the image differencing technique for the Normalized Difference Vegetation Index (NDVI), the second principal component (PC2), and the TM 4 band (TM 4), as well as the post-classification comparison (PCC) in order to analyze the land use/land cover changes in the South-East Transilvania, Romania. The analysis was performed using two frames from Landsat 5 TM satellite images acquired on August 5, 1993 and July 24, 2009. After applying the NDVI, PC2, and TM 4 image differencing techniques, the images obtained were transformed into change/no change maps.

The real tool for achieving of sustainable development is an integrated landscape management. It was defined by Agenda21. It means an integrated approach to planning and to management of landscape resources. In the Slovak Republic the concept of integrated landscape management overcames development on the theoretical-methodological, conceptual and implementational sites. Current is the integrated landscape management defined in the legislation and desired and implemented by several spatial planning processes.

In 2010-2013 in Rostov region the opportunity of forage production intensification based on the application of adapted to the regional soil climatic conditions, highly effective technologies of forage crop cultivation to supply the dairy cattle with farm-produced forages was studied. It was revealed that the optimized dairy cow diet should be as following: hay – 13.4%, silage – 15.8%, root crops – 6.5%, green forages – 33.6%, and formula feeds – 30.7%.

In 2013-2014 field research, during which 56 full-height cuts of 5 soil regions of a subband of moderately droughty steppe and steppe with kolkis of Altai Region were put and analysed, was conducted. In the soil cover structure (SCS) the share of chernozem soils is from 65.8% to 68.0%, with prevalence of ordinary chernozems (40.1-48.0%) over lixivious chernozems (17.5-25.7%). Chernozem and meadow and meadow and chernozem soils takes from 13.4% to 18.3%, and the soil of the salted row - from 2.8% to 8.1%.

Integration of the Russian Federation in the international community, to find the most effective ways to implement the military and land reforms require a comprehensive study. The paper identifies the main problems that hinder the effective implementation of the reform of the conversion, the ways of their solutions, including use of the experience of the advanced countries of the European Union. Identified military objects to be conversion, shown combining them into groups according to various criteria. Proposed a typology of ex-military territories.

Currently, there is a major concern about the future of nutrient loads discharged into the Baltic Sea from Polish rivers because they are main contributors to its eutrophication. To date, no watershed-scale studies have properly addressed this issue. This paper fills this gap by using a scenario-modeling framework applied in the Reda watershed, a small (482� km²) agricultural coastal area in northern Poland. We used the SWAT model to quantify the effects of future climate, land cover, and management changes under multiple scenarios up to the 2050s.

The aim of this article has been to identify and evaluate main factors which influence the agricultural land market in Poland. Statistical data from two institutions, namely the Agricultural Property Agency (APA) and the Central Statistical Office (CSO) as well as the author’s research have been used in the paper. The time horizon of the analysis covers the years 1992-2012. The lower limit was determined by the start of operation of the Agency of Agricultural Property of the State Treasury and the launching of a process of transformation in agriculture state.

Vegetation models are essential tools for projecting large-scale land-cover response to changing climate, which is expected to alter the distribution of biomes and individual species. A large-scale bioclimatic envelope model (RuBCliM) and an individual species based gap model (UVAFME) are used to simulate the Russian forests under current and future climate for two greenhouse gas emissions scenarios. Results for current conditions are compared between models and assessed against two independent maps of Russian forest biomes and dominant tree species.
