Since the reform and opening up, a large proportion of the Chinese rural labor force has transferred to urban and non-agricultural industries. Rural labor transfer not only changes the allocation of household labor in agricultural and non-agricultural sectors but also affects the utilization of other agricultural production factors. Based on data from 818 households in three counties in northern Jiangsu province, this paper analyzed the impact of labor migration on farmers’ adoption of cultivated land quality protection (CLQP) behaviors. The survey results showed that farmers’ awareness of CLQP was still very weak, and the proportion of farmers adopting measures such as subsoiling, straw application, cover crops and green manures and the complementary use of organic fertilizers was still relatively low. The empirical results showed that perennial out-migration for work can constrain households’ protective inputs into soil conservation, but part-time farming locally can promote households’ inputs. The results also showed that farmer characteristics, farming conditions and external environment also significantly affected the farmers’ adoption of soil conservation practices. According to these conclusions, this paper puts forward the corresponding policy implications. Full article

The purpose of this paper is to investigate the impacts of farmers’ cognition of cultivated land quality protection (CLQP) on their behavioral response to land use practices. To this end, this paper establishes a theoretical framework linking farmers’ cognition (on CLQP status, policies and patterns) to their behavioral response (choices of farming methods, land inputs and agricultural waste disposal methods). A field survey was conducted in suburban areas in Liaoning province, Northeast China. A total of 240 households were selected using stratified random sampling. Results show that: (i) in regards to household cognition on CLQP, although a majority of households agree that CLQP is important and have a strong willingness to protect cultivated land quality, their cognition on the future prospect of CLQP is not optimistic; (ii) with regard to household responses to land use practices, a number of households have realized the importance of crop rotation, however, the use of chemical fertilizers is mostly based on past experience and is often excessive. Besides, the disposal of agricultural waste is inappropriate; (iii) household cognition on CLQP policies is found to be the most powerful factor that could lead to an improvement of CLQP practices. It is thus concluded that the government should help households adopt effective farming methods which are environmentally-friendly and sustainable by enhancing publicity of CLQP policies and strengthening farmers’ confidence in CLQP.
