Sun Han (Chairman of the Political Consultation Conference of Jiangsu Province)  
With the rapid growth of population,there has been a decrease in natural resources such as arable land and water.The population pressure on natural resources for a long time has led to the overuse of natural resources and the deterioration of ecological environment in large areas in China.As a result,agricultural products and farmers'income have decreased. To meet the food demand,we must improve the natural resource utilization efficiency by both exploiting and economizing resources.The major measures must be taken as follows:(1)protect arable land and raise the per unit yield;(2)exploit water areas,mountainous regions,grassland and other natural resources,and expand food sources.In addition,the full development of rural labour resource will also play an important role in developing agricultural production and increasing food supply in China.
