Possibilities and requirements for introducing agri-environment measures in land consolidation projects in China, evidence from ecosystem services and farmers' attitudes

The reductions of ecosystem services (ES) initiated by land consolidation towards intensive agriculture has been recognized inmany parts of the world. Land consolidation in China is experiencing a transformation towards sustainability, which may be promoted by learning the experience of Europe to introduce agri-environment measures (AEM). This paper focused on the typical engineering works of land consolidation projects (LCP) to discuss the requirements and possibilities of introducing AEM in LCP in China. Evidence was sought through the ES changes and farmers' attitudes. Based on a database collected from the literature, the changes of ES under LCP across China were evaluated. Household interviews were conducted to identify farmers' perception of ES changes under LCP and their preference of AEM in LCP. In consisted with our expectation, our study demonstrated the negative impacts of LCP on the environment, that the present agricultural-focused LCP in China have typically generated increases in the arable land but decreases in non-crop habitats, and extensively caused growths in food supply ES but reductions in biodiversity maintenance ES. This tendency would threaten the provision of multiple ES and the ultimate sustainability of agriculture. It reflected the urgent requirements of environment integration in LCP in China, for which AEM are efficient instruments. Our results further illustrated the high possibilities of introducing AEM in LCP based on the evidence that the AEM welcomed by the majority of farmers involved all the engineering works, although the farmers selected AEM mainly due to their pursuit of aesthetic instead of biodiversity consideration. To promote land consolidation in China towards sustainability, it is essential to integrate ES into the goals of land use policy, set up the quantitative parameter controlling for noncrop habitats, and introduce AEM in LCP guidelines.
