“…Coastal regions are exposed to a wide variety of hazards, such as landscape changes, habitat loss, seawater intrusion, coastal flooding and waterlogging, which are exacerbated by climate change [31,32,33]. Moreover, many marine and coastal projects have been developed to meet human needs [34,35], and the demand for such developments in coastal regions is often met by exploiting natural land (e.g., tidal flats, water, and open spaces), which may considerably reduce the area of ecological land [27]. Importantly, China’s growing economy is increasingly concentrated in coastal regions [36]; thus, the outline of the Jiangsu coastal reclamation development plan (2010–2020) was passed in 2009 [27], and landscapes such as tidal flats, and areas of cordgrass and open seawater are to be used for agriculture and urban development.…”

Detailed analysis of the evolution characteristics of landscape ecological risk is crucial for coastal sustainable management and for understanding the potential environmental impacts of a man-made landform landscapes (MMLL). As a typical open coastal wetland, large-scale human activities (e.g., tidal reclamation, fishery activities, wind farm construction, and port construction) have substantially affected the evolution of the coastal ecological environment. Previous landscape ecological risk assessment studies have documented the effectiveness of assessing the quality of ecological environment processes. However, these studies have either focused on the noncoastal zone, or they have not considered the evolution of the spatial characteristics and ecological risk evolution of the landscape at an optimal scale. Here, we present a landscape ecological risk pattern (LERP) evolution model, based on two successive steps: first, we constructed an optimal scale method with an appropriate extent and grain using multi–temporal Landsat TM/OLI images acquired in the years 2000, 2004, 2008, 2013 and 2017, and then we calculated landscape ecological risk indices. Based on this model, the entire process of the spatiotemporal evolution of ecological risk patterns of the open coastal wetlands in Jiangsu, China, was determined. The principal findings are as follows: (1) The main landscape types in the study area are tidal flats and farmland, and the main features of the landscape evolution are a significant increase in aquafarming and a substantial decrease in the tidal flat area, while the landscape heterogeneity increased; (2) In the past 20 years, the areas of low and relatively low ecological risk in the study region were greatly reduced, while the areas of medium, relatively high, and high ecological risk greatly increased; the areas of high-grade ecological risk areas are mainly around Dongtai and Dafeng; (3) The area of ecological risk from low-grade to high-grade occupied 71.75% of the study area during 2000–2017. During the previous periods (2000–2004 and 2004–2008), the areas of low-grade ecological risk were transformed to areas of middle-grade ecological risk area, while during the later periods (2008–2013 and 2013–2017) there was a substantial increase in the proportion of areas of high-grade ecological risk. Our results complement the official database of coastal landscape planning, and provide important information for assessing the potential effects of MMLL processes on coastal environments.

“…The method is coarse and still requires further improvements in order to allow analysis of results with greater detail. Although some research indicates that the macrozoobenthos communities can benefit from lower-intensity changes [2], the coastal reclamation area will take more than 30 years to recover to its equilibrium [47,73]. The dynamic interactions between the land and ocean make ecosystems of the coastal wetlands more vulnerable than other regions.…”

“…Reclamation occurred around 1950 in the western part of the study area, and most of the marsh wetlands were reclaimed for aquiculture pond and cropland. Notably, the Outline of Jiangsu Coastal Reclamation Development Plan (2010-2020) was released by the State Council of China in 2009, which has greatly accelerated the pace of reclamation in the study area [47]. …”

Abstract:Reclamation is capable of creating abundant land to alleviate the pressure from land shortages in China. Nevertheless, coastal reclamation can lead to severe environmental degradation and landscape fragmentation. It is quite important to monitor land use and cover change (LUCC) in coastal areas, assess coastal wetland change, and predict land use requirements. The siltation of tidal flats will result in the dynamic growth and continuous expansion of coastal areas. Therefore, the process of land change in coastal areas is different from that under the fixed terrestrial boundary condition. Cellular Automata and Multi-Agent System (CA-MAS) models are commonly used to simulate LUCC, and their advantages have been well proven under the fixed boundary condition. In this paper, we propose CA-MAS combined with a shoreline evolution forecast (CA-MAS-SEF) model to simulate the land change in coastal areas. Meanwhile, the newly increased area, because of the dynamic growth of tidal flats, is considered in the simulation process. The simulation results using the improved method are verified, and compared with observed patterns using spatial overlay. In comparison with simulation results that do not consider the expansion of tidal flats, the Kappa coefficient estimated while considering the dynamic growth of tidal flats is improved from 65.9% to 70.5%, which shows that the method presented here can be applied to simulate the LUCC in growing coastal areas.

“…To evaluate the ecological changes appropriate to Jiangsu's coastal wetland, Caiyao Xu et al analyzed ecological security and ecosystem services in the region by using remote sensing and spatial analyses for the period from 1977 to 2014 [4]. They found that the total ecosystem service value decreased significantly from $2.98 billion per year to $2.31 billion per year over the study period due to this transformation from open to built-up land.…”

“…Moreover, it will take 34 years for landscape ecological security and 39 years for ecosystem services to regain their original state of equilibrium. Nonetheless, food production was the only ecosystem service function that consistently increased, mainly because of government policy, implying that government regulation or incentives regarding the transformation and/or utilization of the land could be the best solution for green growth in the region [4].…”

This Special Issue consists of selected papers from the annual international Sustainable Asia Conference (SAC) 2016, held on Jeju Island, South Korea, from 28 June to 2 July 2016. SAC 2016 is one of the leading international conferences for presenting novel and fundamental advances in sustainable development issues for Asia. In this special issue, most of the papers emphasize the importance of sustainable governance in harmonizing economic development with a healthier life, while enhancing the quality of all economic activities. The majority of papers in this special issue also deal with problems of urbanization, because the Northeast Asian countries are experiencing the transformation of their economic structure from quantitatively oriented development to the qualitative, highlighting socioeconomic performance. There has been a vast amount of discussion and many ideas put forward on sustainable development, but as the Marrakech Proclamation of COP 22 concluded in November 2016, it is now time to meet the practical challenges of sustainable development. This special edition will shed light on the action plan against global warming and environmental degradation.
