Environmental impacts of a rice-beef-biogas integrated system in the Mekong Delta, Vietnam evaluated by life cycle assessment.

It is essential to increase the production of foods to meet the increasing future food demand, but this should be done in an environmentally sustainable manner. Integrated crop-livestock systems have been suggested to balance the reduction of environmental impacts and the increase in food production. Here we assessed and compared the environmental impacts of specialized (SPC) and integrated (ITG) rice and beef production systems in the Mekong Delta, Vietnam, using a life-cycle assessment (LCA).

[Dynamics and ecological significance of nitrogen wet-deposition in Taihu Lake region--taking Changshu Agroecological Experiment Station as an example].

Nitrogen wet deposition was monitored for two years (2001.6-2003.5) at the Changshu Ecological Station in Taihu Lake region.
