Land use/Land cover change (LUCC) is one of the important reasons for the change of ecosystem services (ESs).Due to the uncertainty of future development policies and the complexity of LUCC, assessing the impact of future urban sprawl on ecosystem services remains challenging. We simulated the effect of urban land-use change on ESs on the basis of different functional scenarios, which is of important value to urban land-use planning and ESs protection. In our study, we designed three scenarios: Production function priority scenario (PFP scenario)?Living function priority scenario (LFP scenario)?Ecological function priority scenario (EFP Scenario). And we used the GeoSOS-FLUS software to realize visualization. Based on invest model, we evaluated five types of ESs: carbon storage, warter yield, habitat quality, water purification and soil conservation. Research showed that from 2000 to 2015, carbon storage, habitat quality and water production in Nanjing decreased significantly, soil conservation increased slightly, and the performance of the two indicators for water purification was not consistent. From different scenarios, carbon storage and habitat quality were the highest in EFP scenario, water yield was the highest in PFP scenario and soil conservation was the highest in LFP scenario. We analyzed the trade-offs among various ESs, found that the change of land-use types in cities does not fundamentally change the trade-offs among various ESs. We believed that the determination of the main function of LUCC was the first condition to judge the applicability of scenario, and the scenario simulation which integrated the main function of the city could provide more references for the related research.

China’s ecological compensation (EC) is based on the property rights structure of public ownership of natural resources, which should be based on the spatial planning, which is defined by local government as the boundary of property right management and the distribution of development power. This study combined spatial planning and ecosystem service value (ESV) accounting to design a decision-making framework of EC, which includes “Subject choice, Value accounting, Priority evaluation, Policy supply”. We selected 32 counties (districts) in the Yangtze River Delta region as the research object with the consideration of spatial planning and expert advice, and found that the implementation of EC slowed down the urbanization process and promoted the increase of ecological space. We conducted an accounting and sensitivity analysis on the spatial and temporal changes of ESV in the region from 2000 to 2019, and finally determined the amount and priority of accepting EC. The research results show that the ESV in the study area shows a general trend of increasing and then decreasing in time, and a spatial pattern of high in the south and low in the north and high in the east and low in the west. Forestland and water area are the main providers of ESV in the study area. The sensitivity coefficients of each type of ESV do not change much in each period, but the coefficients between the types have large differences. The total amount of EC in the Yangtze River Delta ecological barrier (YRDEB) is RMB 38,098.11 billion, and Shitai County is the area with the highest priority for compensation. We believe that this decision-making framework has the potential to be applied to the implementation of EC in other regions of China. At the same time, it can also be used to enrich the international views on EC research.

As in many other parts of the world, Australian agriculture is facing increasing challenges resulting from domestic and global economic, political, social and cultural changes. Added to these challenges are the uncertainties caused by climatic variations. The Australian way of handling some of these major challenges is highlighted in this chapter. Increasingly uncertain world markets and volatile weather conditions (especially severe floods and droughts) are two major complications that make farming in Australia most challenging. The ways in which these two challenges are handled are presented. The chapter also discusses how biosecurity threats, farm succession, labour and skills shortage, strong public demand for environmental protection, and the urban-rural divide are being addressed.
