Agricultural Sustainability in the Food Bowl of the North China Plain

Abstract

The North China Plain (NCP) is the food bowl of the country. To feed the growing population, farmers in the area have been using the land very intensively with high inputs to increase food production. The sustainability of such farming practices has attracted the attention of scholars, planners and decision makers. This study analyses the economic and environmental sustainability of the major cropping systems in the NCP, based on selected site-specific indicators. The information necessary for this study was obtained in 2001 through a survey of 270 farm households from four villages in Ningjin county, soil sample analysis, chemical tests for nitrate concentration in groundwater and crop plants, field observations and discussions with key informants, as well as official reports and publications. The findings of the analysis revealed that all cropping systems in the study area were economically sustainable. However, such achievements have been made at a cost to the environment, degradation of natural resources and risk to human health. If these costs are taken into consideration, all cropping systems in the study area cannot be considered sustainable. The study stresses that farming practices that are economically sustainable should not be promoted at the cost of degrading production resources. There is a need for a policy shift from the promotion of agricultural production to sustainable agricultural production. Several policy measures have been outlined for the promotion of sustainable cropping systems in the NCP.
