Despite the looming land scarcity suited for agricultural expansion, farmland abandonment is widespread globally. The recultivation of some abandoned farmlands could unlock untapped potential. Yet, little known about determinants recultivation. To better understand behavioral intentions farmers regarding lands, we concentrated on Buryat Republic in Russia, where and with different ethnicities c...

In most habitats in temperate zones, Carabidae show clear intra-annual changes abundance and species composition. the spring, we studied beetle fauna 5 different biotopes differing degree of overgrowth birch forest over a period three years. According to years research, 10,528 specimens (64 from 6 subfamilies) were collected. Twelve beetles found all biotopes. The highest numbers obtained 12-15...

Growing biomass feedstocks from marginal lands is becoming an increasingly attractive choice for producing biofuel as an alternative energy to fossil fuels. Here, we used a biogeochemical model at ecosystem scale to estimate crop productivity and greenhouse gas (GHG) emissions from bioenergy crops grown on marginal lands in the United States. Two broadly tested cellulosic crops, switchgrass, an...

The Deckers Creek watershed in northern West Virginia (USA), containing a land area of 166 km2 (63 mi2), has a long history of industrial development and attendant environmental abuses from both land and water pollution practices. The water in Deckers Creek was sampled in 1974 at 29 locations along the main stem and resampled in 1999-2000 to determine water quality changes over this 25-year per...

Understanding effects of land-use changes driven by the implementation of the "Grain for Green" project and the corresponding changes in soil organic carbon (SOC) storage is important in evaluating the environmental benefits of this ecological restoration project. The goals of this study were to quantify the current soil organic carbon density (SOCD) in different land-use types [cultivated land...

increased soil dryness of hillsides and lands around the gully causes the aggravation of the gully erosion which leads to the desertion of the environment. soil moisture contents are various in different soil depths, gully positions, and in various land uses. these are fundamental for ecosystem sustainability in arid and semi-arid area. therefore, understanding the behavior of soil moisture in ...

Large areas of tropical forests have been converted to agricultural land and subsequently abandoned. If restoration can occur on these abandoned lands, it offers great potential for biodiversity recovery, carbon sequestration, and enhanced ecosystem services. To understand the interaction between different forms of anthropogenic degradation and restoration strategies we examined biomass accumul...
