The Đorđevačka (Davidovačka, Vrtogoška) River is a left tributary of the Južna Morava River, into which it flows at approximately 5 km north-east from Bujanovac. The paper presents the results of a study of change of intensity of erosion processes in 1953, 1970 and 2011. The erosion process intensity in 1953 and 1970 was established on the basis of available erosion maps, whereas in 2011 it was determined by means of satellite images and field mapping.

Urbanization is a major threat on biodiversity due to the direct destruction of natural and semi-natural habitats and to the indirect impacts caused by urban areas beyond their limits. In this study, we proposed a methodological framework to assess the potential impacts of current and future urbanization on high diversity sites and their associated species across the entire French Mediterranean region. Using a 100 m grid cell, we adapted a land-use change (LUC) model to project future urbanization over a 20 years period.

Land use change has become increasingly acknowledged as an important issue in terms of understanding the processes of global change. Hence, land use decision-making by smallholder communities in developing countries become a vital part of the broader comprehension of environmental and social change that are related to the change processes at the global scale. A wide range of analytical and conceptual frameworks has been developed to facilitate and sharpen such analyses, ranging from very theoretical to directly operational approaches.

Grassland degradation has been caused by overgrazing in Inner Mongolia. Previous studies revealed the effect of grazing pressure on the vegetation and soil. However, that of different land use types (i.e., grazing and mowing) has not been fully understood, though land use has been dramatically changed from grazing to mowing after land contract system was introduced in 1996. The objective of this study, therefore, was to evaluate that effect on the vegetation and soil.

In the Republic of Lithuania the average land productivity score is about 41.8. However, in separate elderates it ranges from 30.5 to 55.1. As a result, it determines different intensity of using agricultural farming lands. Research object - agricultural farming lands in rural municipalities of the republic of Lithuania. Aim of the research – identify the intensity of using Lithuanian agricultural farming lands for agriculture.

“Substantial downzoning” is defined as the exercise of police power to significantly reduce the legally permitted density on undeveloped land in a community. This contentious practice is typically challenged by those who perceive the action to limit their market opportunities (e.g., farmers and developers), their sympathizers, and others who prefer the status quo.

Weed problems continue to be an obstacle in plant protection and in natural areas, causing high costs of control and asking for adequate prevention measures. New weed problems in any given area (risk area) may arise from three basic sources: by introduction and naturalization of new weedy plant species, by increasing spread of weedy taxa that are already present in the risk area, and by the evolution of new weedy taxa in the risk area.

In the scope of the European Union water initiative for developing countries, the research programme RIVERTWIN (A Regional Model for Integrated Water Management in Twinned River Basins) was initiated for three river basins, Neckar in Germany, Ouémé in Benin Republic and Chirchik in Uzbekistan. Our contribution to development of the model at regional level was the establishment of a Soil and Land Resources Information System for the Ouémé basin (SLISYS-Ouémé). The objective of the SLISYS was to provide information about soil, climate and land use in the Ouémé basin.

The Greenhouse Gases from Agriculture Simulation Model (GreenAgSiM) presented in this paper aims to quantify emissions from agricultural activity on a global scale. The model takes emissions into account that are directly attributable to agricultural production, such as enteric fermentation (methane), manure management (methane and nitrous oxide), and agricultural soil management (nitrous oxide). Furthermore, carbon stock differences from land-use change (carbon dioxide) induced by agriculture are included in the model.

The influence of different vegetation covers of the set-aside land on the volumetric water content (VWC) and its variations during the day in upper soil layers (5 and 15 cm) was observed using the TDR method in 15 min intervals from May to August in 2002 and 2003. A spontaneous fallow was established in autumn 2001 and plots with artificial revegetation sowed with the mixture of Dactylis polygama and Trifolium repens in spring 2002. The experimental plots were mulched twice during the vegetation period. VWC was registered in the same time also on bare ground.
