Shenzhen, the first special economic zone of China, has witnessed earth-shaking changes since the late 1980s. In the past 35 years, about 80 km 2 of land has been reclaimed from the sea in Shenzhen. In order to investigate coastal vertical land motions associated with land reclamation, we proposed an elaborated Point Target (PT) based Small Baseline Subset InSAR (SBAS-InSAR) strategy to process an ENVISAT ASAR ascending and descending orbits dataset both acquired from 2007 to 2010. This new strategy can not only select high density PTs but also generate a reliable InSAR measurement with full spatial resolution. The inter-comparison between InSAR-derived deformation velocities from different orbits shows a good self-consistency of the results extracted by the elaborated PT-based SBAS-InSAR strategy. The InSAR measurements show that the reclaimed land is undergoing remarkable coastal subsidence (up to 25 mm/year), especially at the Shenzhen Airport, Bao'an Center, Qianhai Bay and Shenzhen Bay. By analyzing the results together with land reclamation evolution, we conclude that the ground deformation is expected to continue in the near future, which will amplify the regional sea level rise.

“…Although China has made remarkable progress in conserving and restoring coastal wetlands since 2002 (Bi et al, ), there are increasing threats and pressures from population displacement toward coastal areas and rapid coastal development. To establish more resilient coasts and reduce the impact of future hazards and rapid recovery of the system's functionality, it is necessary to evaluate the vulnerability of coastal communities and take structural and nonstructural measures coupled with natural features like coastal wetlands and other potential natural habitats (Silliman et al, ).…”

Worldwide, humans are facing high risks from natural hazards, especially in coastal regions with high population densities. Rising sea levels due to global warming are making coastal communities' infrastructure vulnerable to natural disasters. The present study aims to provide a coupling approach of vulnerability and resilience through restoration and conservation of lost or degraded coastal natural habitats to reclamation under different climate change scenarios. The integrated valuation of ecosystems and tradeoffs model is used to assess the current and future vulnerability of coastal communities. The model employed is based on seven different biogeophysical variables to calculate a natural hazard index and to highlight the criticality of the restoration of natural habitats. The results show that roughly 25% of the coastline and more than 5 million residents are in highly vulnerable coastal areas of mainland China, and these numbers are expected to double by 2100. Our study suggests that restoration and conservation in recently reclaimed areas have the potential to reduce this vulnerability by 45%. Hence, natural habitats have proved to be a great defense against coastal hazards and should be prioritized in coastal planning and development. The findings confirm that natural habitats are critical for coastal resilience and can act as a recovery force of coastal functionality loss. Therefore, we recommend that the Chinese government prioritizes restoration (where possible) and conservation of the remaining habitats for the sake of coastal resilience to prevent natural hazards from escalating into disasters.

“…Penambahan luas lahan melalui kegiatan reklamasi biasanya dilakukan di daerah pesisir dipilih sebagai solusi ruang atas kepadatan dan tingginya aktivitas perkotaan di daratan utama (Peng et al, 2013). Reklamasi pantai telah memperluas pemanfaatan sumber daya dan ruang, serta memberi kontribusi yang signifikan terhadap proses pertumbuhan ekonomi dan urbanisasi di Belanda, Jepang, Korea Selatan, dan China (Bi et al, 2012). Reklamasi juga menyebabkan pemekaran kota menjadi lebih intensif di pesisir sebagai imbas dari fenomena pertumbuhan penduduk yang tinggi, perkembangan ekonomi yang pesat, dan kontrol laut yang tidak memadai .…”

Land is one of limited natural resources. The high requirement of land made technology develop by reclamation method. The purpose of reclamation should be for increasing the benefit of natural resources and community welfare, but in fact the reclamation contribute the environmental problem and social conflict. The aims of this research are analyzing the sustainability of marine and coastal resources in Benoa Bay Reclamation Site based on 4 dimension, there are Environmental, Social, Economic, and Marine Spatial Utilization. This research was conducted quantitative approach by Multidimensional Scaling (MDS) for assessing the sustainability of marine and coastal resources. The result of research shows sustainability value of each dimension in sequence starting from the lowest is Marine Spatial Utilization (44,31%-Less Sustainable), Social (49,79%-Less Sustainable), Environmental (49,88%-Less Sustainable). The overall sustainability value of marine and coastal resource analysis in Benoa Bay reclamation site is 43,15% (Less Sustainable). Further consideration is needed if the reclamation plan is to be implemented in Benoa Bay.
