Modeled nitrogen deposition rates were particularly elevated for the Coastal Plain. Having more animals than required for optimal production – which is often the case as a larger herd size supports non- production functions of livestocksuch as manure productiondraught, traction and capital storage – goes at the expense of animal-source food output.

At most locations the dry summer period lengthened, exacerbating the greater erosion risk due to lower ANPP. We quantified LWP for various farms in mixed-crop livestock systems and explored the effect of household demographic characteristics and farm assets on LWP using ANOVA and multilevel mixed-effect linear regression.

A Compound growth rate analysis. Significant difference in feed collected, freshwater evapotranspired, livestock outputs and water productivity WP were observed between wealth groups, where wealthier are relatively more advantaged. The distribution of TVW calculated by us and the distribution of actual water resources have remarkable difference, which leads to the increase of water consumption and cost of agricultural production.

Sustainable Livestock ProductionHealth, and Environment in the We found no evidence that the system incorporating a cattle breed popular as a conservation grazer was any better for bird and butterfly species richness than those based on a mainstream breed, yet methane emissions from such a system were predicted to be higher.

As a result, local policies are being implemented to safeguard the. Development in organic farming has been stimulated by farmers and consumers becoming interested in healthy food products and sustainable environment. It is necessary to strengthen food supply by maximizing gatlic resources; improve food distribution system to guarantee a stable food supply and public access; encourage diversified food consumption; and prevent as well as resolve food scarcity.
