Coupling coordination analysis of rural production-living-ecological space in the Beijing-Tianjin-Hebei region

Understanding the impacts of urban expansion on ecosystem services (ESs) is important for sustainable development on regional and global scales. However, due to the uncertainty of future socioeconomic development and the complexity of urban expansion, assessing the impacts of future urban expansion on ESs remains challenging. In this study, we simulated the urban expansion in the Beijing-Tianjin-Hebei (BTH) urban agglomeration in China from 2013 to 2040, and assessed its potential impacts on ESs based on the Shared Socioeconomic Pathways (SSPs) and the Land Use Scenario Dynamics-urban (LUSD-urban) model. We found that urban land in the BTH urban agglomeration is expected to increase from 7605.25 km 2 in 2013 to 9401.75–11,936.00 km 2 in 2040. With continuing urban expansion, food production (FP), carbon storage (CS), water retention (WR), and air purification (AP) will decrease by 1.34–3.16%, 0.68–1.60%, 0.80–1.89%, and 0.37–0.87%, respectively. The conversion of cropland to urban land will be the main cause of ES losses. During 2013–2040, the losses of ESs caused by this conversion will account for 83.66–97.11% of the total losses in the whole region. Furthermore, the ES losses can cause considerable negative impacts on human well-being. The loss of FP will be equivalent to the food requirement of 3.68–8.61% of the total population in 2040, and the loss of CS will be 2.55–6.01% of the total standard coal consumption in 2013. To ensure sustainable development in the region, we suggest that effective policies and regulations should be implemented to protect cropland with high ES values from urban expansion.

How do population decline, urban sprawl and industrial transformation impact land use change in rural residential areas? A comparative regional analysis at the peri-urban interface

Sustainable production and consumption in the rural regions remains a barely tried yet important issue for contributing to rural sustainability these days. In particular, the sustainable livelihood of rural farmers has not been fully investigated for those in rural areas with high agricultural pollution emissions and a poor ecological quality of agricultural production in China. Also affected are farmers with a low living standard and output, or suffer from social inequity. The sustainable livelihood security (SLS) index therefore provides a useful means of identifying the existence of the conditions necessary for sustainable livelihood or sustainable development. Using the fuzzy comprehensive method, this paper aims to assess the level of sustainable livelihood security of China’s provincial farmers and its three components of ecological security, economic efficiency and social equity. A SLS index is established and the entropy weight method used to determine the weight of the indices and analyze spatial distribution. The results indicate that the sustainable livelihood security index and its components vary between provincial regions, with the western provinces being most adversely affected, sustainable livelihood, economic efficiency and social equity being the least secure (or relatively insecure) in the western provinces while economic efficiency is most secure (or relatively secure) in the eastern and middle provinces, and social equity most secure in the eastern provinces. Concluding remarks suggest policies designed to improve the sustainable livelihood security of farmers according to local regional circumstances.
