Finding solutions to the complex problems of grassland rehabilitation and improvement in household incomes for the herders dependent upon livestock production from grasslands requires the development of integrated modelling tools to identify the more likely solutions that can then be tested over time on farms. This paper outlines a dynamic bioeconomic model designed to analyse the main options available to improve grasslands and income from livestock on low-productivity grasslands in northern China. The model requires basic information obtained from farm surveys to structure the livestock production system and uses general relationships between livestock consumption of grasslands and grassland productivity, plus functions that simulate erosion and soil fertility loss due to wind, to estimate longer term productivity and financial returns. Initial simulations show the benefits of managing grazing pressures to higher levels of herbage mass than would be current practice on farms.
