Chicken Farming in Grassland Increases Environmental Sustainability and Economic Efficiency
BACKGROUND Grassland degradation caused by overgrazing poses a threat to both animal husbandry and environmental sustainability in most semi-arid areas especially north China. Although the Chinese Government has made huge efforts to restore degraded grasslands, a considerable attempt has unfortunately failed due to an inadequate consideration of economic benefits to local communities.

متن کاملObject view in spatial system dynamics: a grassland farming example
Spatial system dynamics (SSD) models are typically implemented by linking stock variables to raster grids while the use of object representations of human artefacts such as buildings or ownership has been limited. This limitation is addressed by this article, which demonstrates the use of object representations in SSD. The objects are parcels of land that are attributed to grassland farms. The ...
متن کاملStudying Drought Tolerance in Thymus kotschyanus Accessions for Cultivation in Dryland Farming and Low Efficient Grassland
This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity...
متن کاملComparing intensive, extensified and organic grassland farming in southern Germany by process life cycle assessment
To reduce the environmental burden of agriculture, suitable methods to comprehend and assess the impact on natural resources are needed. One of the methods considered is the life cycle assessment (LCA) method, which was used to assess the environmental impacts of 18 grassland farms in three different farming intensities — intensive, extensified, and organic — in the Allgäu region in southern Ge...
