Two adult oak tree groups in northern Serbia, differing in degree of decline, were studied. Measurements of pre-dawn water potential (PWP), nutrient status and radial growth were performed and compared with similar sites in Slovenia. In spite of favourable water conditions and sufficiently high groundwater table, values of PWP between groups were statistically significant, with lower values in the degraded group. Growth and nutrient analysis confirmed differences between the groups, while values of PWP did not indicate water stress.

Satellite data use is finding global applications because they provide repeated cover, broad information, high electromagnetic spectral resolution, and software-hardware compatibilities. This study aims to evaluate of the Landsat TM data capabilities in land-use mapping of Bazoft River basin (Chahar Mahale Bakhtiary Province). Six spectral bands of the Landsate TM were employed to produce land-use map of the Region. The date of image acquisition was May 5th, 1998. Performance of the geometric correction completed with RMSE= 1.008 pixels. Various image enhacement methods (e.g.

Advanced biofuels such as cellulosic ethanol are of great interest for their potential to supply a significant portion of U.S. fuel needs plus advantages over corn grain-based ethanol. The sustainability of agriculture-based advanced biofuels depends on how farmers would respond in providing biomass feedstock, yet economic behavior by farmers has been under recognized by the science community. Focusing on markets and policy incentives, this research shows that farmers are unlikely to convert current grain cropland to grow a dedicated cellulosic biomass crop such as switchgrass.

The current state was studied and main trends of land use development under the influence of changing climate and anthropogenous influence were revealed. The spatial structure, direction and features of regional development of agricultural production in new market conditions of Russia and Kazakhstan was estimated. Creation of agroforestal complexes which have to become a necessary component when forming the profitable country farms located discretely in primordially treeless territories and applying resource-saving technologies was offered for its optimization.

The planning approach to prevailing small hydropower is still to be established. The varying characteristics of hydropower products such as type, color and shape may affect regional landscape characteristics. The objective of this study is to recognize the impact of potential landscape change by prevailing small hydropower in hilly and mountainous regions that are advantaged in water resources and natural landscape. The study areas were the Minamioguni Town and Itsuki Village in Kumamoto Prefecture.

Integrated water resources management is a combination of managing blue and green water resources. Often the main focus is on the blue water resources, as information on spatially distributed evaporative water use is not as readily available as the link to river flows. Physically based, spatially distributed models are often used to generate this kind of information. These models require enormous amounts of data, which can result in equifinality, making them less suitable for scenario analyses.
