Approximately 70 percent of the contiguous United States is in private lands with half of this total in row crop or rangelands. Audubon California’s Landowner Stewardship Program engages with farmers and ranchers on conservation and restoration projects in a manner compatible with existing agricultural operations. To assess the success of these efforts, Audubon, University of California, Davis,...

this study aimed to determine the effect of land use changes from rangeland to horti-agricultural lands on the most important qualitative characteristics of soil such as total soil carbon and particulate organic matter, in salavatabad region, sanandaj. in the present study, one rangeland, two cultivated pea lands, two cultivated wheat lands and two gardens were selected in growth season in the ...

The high cost of transportation fuels and the environmental risks associated with acquiring and using nonrenewable energy sources have created a demand for developing renewable bioenergy crops. Switchgrass ( L.), a warm-season perennial grass, is a promising feedstock due to its high biomass production under a wide range of growing conditions and its satisfactory forage quality and chemical com...

In Mediterranean environment intensive agricultural activities are often practiced in steep slopes, where sometimes climatic, geomorphologic and land use factors (e.g. the high rainfall intensity, the scarce vegetal coverage, especially on the occasion of the early rainfalls, the low organic matter content of soils, etc.) worsen the impacts of soil erosion. In such contexts agriculture may play...

Background & objectives: Irrigation water quality is a critical aspect of agricultural production especially in terms of human health and the environmental aspects. The aim of this study was to estimate the level of surface runoff and groundwater pollution used in the production of agricultural products in the south of Tehran. Methods: Sampling points included 14 points of surface water collec...

Abstract Background In the climate change context, nature-based solution (NBS) is considered one of effective tools to increase resilience socio-ecological system. The concept coincides with government’s attempts afforestation and reforestation programs that have been going on for 60 years in Bangladesh. This study, therefore, envisaged understanding how NBS (mangrove reforestation) works promo...

Grassland bird species have experienced substantial declines in North America. These declines have been largely attributed to habitat loss and degradation, especially from agricultural practices and intensification (the habitat-availability hypothesis). A recent analysis of North American Breeding Bird Survey (BBS) "grassland breeding" bird trends reported the surprising conclusion that insecti...
