Ellis, Sustainable Agriculture in China- Homepage
For more than one thousand years, China's Tai lake region has
sustained remarkably high levels of agricultural productivity.
By analyzing nitrogen cycling in contemporary and traditional
villages of the region, the ecological basis for this long-sustained
productivity is being investigated. Whole-village N budgets are
being developed from data gathered during more than two years
of field work in Wujin and Wuxi counties of Jiangsu Province.
Methods used include: analysis of agricultural materials, experiments
in farmer's fields, household surveys, GIS land-use analysis,
collection of archival data, and consultation with local experts.
Nitrogen cycling indices derived from whole-village N budgets
are being developed to differentiate N-cycling patterns in traditional
and contemporary agroecosystems and to detect relationships between
N-cycling patterns and ecologically-sustainable productivity.
KEYWORDS: Sustainable agriculture, traditional agriculture, agroecology, village scale agroecosystems, wetland rice, agriculture history, nitrogen cycling, nutrient limitation, China.
