increasing water shortage and inadequate science

technology and education are restrictive factors for sustainable development of the agricultural environment in Dongchnagfu County.The principles of eco-agriculture provide powerful means to abate damage to and sustain agricultural and environmental systems.These principles are to adjust measures to local conditions

to establish a cyclical and regenerative economy and to recognise the economic

social and ecological benefits of change. Elements of ecoagricultural construction include reforming farmland environments

water-farmland-forest relationships

farmland fertility and farmland structure. These changes are considered with development models for greenhouse/climate change actions

methane generation
