China is a maritime power. However, as its economy develops rapidly, China lacks freshwater resources. The water resources per capita are low in China and are less than a quarter of the global mean value. The development and utilization of desalination, a new unconventional water resource in coastal areas, has gradually attracted the attention of the central and local governments. This paper introduces three aspects of the comprehensive utilization of seawater in China, including the desalination of seawater, the direct use of seawater, and the use of seawater as a chemical resource. Based on the recent status (2017) of comprehensive seawater utilization in China, the prospects for optimizing the utilization of seawater resources are presented. Furthermore, the restrictive factors and potential countermeasures for the increased use of seawater desalination are investigated. Several recommendations are presented, specifically, improving the laws, using regulations and standards related to desalination, strengthening the policies that support enterprises that use desalination, gradually improving the localization rate of key technologies and equipment, and devoting additional attention to the problems associated with brine processing. Seawater is expected to become an important supplemental source of water in coastal areas of China, and the resources needed for its use will be developed as a strategic and influential industry.

China has adopted a transfer-based fiscal decentralisation scheme since the mid-1990s. In the 1994 tax sharing reform, the central government significantly raised its share of government revenue vis-à-vis local governments by taking most of the newly created value-added tax on manufacturing. One aim for the adoption of the transfer-based fiscal scheme was to channel more funds to less developed regions and rural areas, and to alleviate growing interregional inequality and urban–rural income disparity. In 2002 and 2003 the Chinese central government further grabbed 50% and 60%, respectively, of the income taxes previously assigned only to local governments while providing more fiscal transfers to the country’s poor regions and the countryside. Utilising the 2002–2003 change in China’s central–local tax sharing regime as an exogenous policy shock, we employ a Simulated Instrumental Variable approach to causally evaluate the effects of the policy shock on growth, interregional inequality and urban–rural disparity. We find the lower local tax share dis-incentivised local governments and led to lower growth. Although higher central transfers helped to reduce interregional inequalities in per capita GDP and per capita income, the equalising effects were only present for urban incomes. We argue that transfer-based decentralisation without bottom-up accountability was detrimental to economic growth and had limited impact on income redistribution.

As the third-largest SO2 emitter in the world, China is facing mounting domestic and external pressure to tackle the increasingly serious SO2 pollution. Figuring out the convergence and persistence of sulfur dioxide (SO2) emissions matters much for environmental policymakers in China. This study mainly utilizes the Fourier quantile unit root test to survey the convergence of the SO2 emissions per capita in 74 cities of China during the period of December 2014 to June 2019, by conducting five traditional unit root tests and a quantile root unit test as a comparative analysis. The empirical results indicate that the SO2 emissions per capita in 72 out of 74 cities in China are convergent in the sample period. The results also suggest that the unit root behavior of the SO2 emissions per capita in these cities is asymmetrically persistent at different quantiles. For the cities with the convergent SO2 emissions, the government should consider the asymmetric mean-reverting pattern of SO2 emissions when implementing environmental protection policies at different stages. For Hefei and Nanjing, the local governments need to enact stricter environmental protection policies to control the emission of sulfur dioxide.

Sepuluh tahun yang lalu putusan Mahkamah Konstitusi Nomor 3/PUU-VIII/2010 telah menegaskan bahwa  bahwa pemberian hak pengusahaan perairan pesisir (HP3) oleh pemerintah kepada pihak swasta bertentangan dengan konstitusi, terutama dengan Pasal 33 ayat (4) UUD 1945. Pembentuk undang-undang kemudian merespon putusan tersebut dengan merevisi UU Nomor 27 Tahun 2007 menjadi Undang-Undang Nomor 1 Tahun 2014 tentang Perubahan Atas Undang-Undang Nomor 27 Tahun 2007 tentang Pengelolaan Wilayah Pesisir dan Pulau-Pulau Kecil. Revisi tersebut telah mengubah Rezim HP3 dari UU 27/2007 menjadi rezim perizinan dalam UU 1/2014. Sayangnya, perubahan tersebut justru menimbulkan berbagai persoalan mulai dari konflik antara undang-undang serta peraturan dibawah undang-undang yang pada akhirnya sangat berpotensi merugikan hak-hak konstitusional masyarakat pesisir pantai. Penelitian ini memfokuskan pada aspek yuridis maupun sosiologis terkait perlindungan hak-hak konstitusional masyarakat pesisir pantai setelah Putusan Mahkamah Konstitusi Nomor 3/PUU-VIII/2010. Penelitian ini secara mendalam membahas mengenai tindaklanjut putusan MK a quo oleh pembentuk undang-undang, pemerintah pusat hingga pemerintah daerah dan stakeholder serta pemenuhan hak-hak konstitusional masyarakat pesisir pantai. Penelitian ini merupakan penelitian hukum normatif dengan cara meneliti Putusan MK Nomor 3/PUU-VIII/2010. Pembahasan secara deskriptif digunakan untuk memahami politik hukum pengelolaan wilayah pesisir sebagai upaya memenuhi hak-hak konstitusional masyarakat pesisir pantai. Disamping itu, Pengelolaan wilayah pesisir secara terpadu yang merupakan proses yang dinamis, multidisiplin, dan berulang untuk mempromosikan pengelolaan kawasan pesisir yang berkelanjutan. Termasuk seluruh siklus pengumpulan informasi, perencanaan, pengambilan keputusan, manajemen dan pemantauan implementasi. Ten years ago, the Constitutional Court Decision Number 3/PUU-VIII/2010 confirmed that the granting of concession rights for coastal waters (after this: HP3) by the government to private parties was contrary against the constitution, especially Article 33 paragraph (4) of the 1945 Constitution. Legislators then respond to the decision to revise Law No. 27 of 2007 as Law No. 1 of 2014 on the Amendment of Law No. 27 of 2007 on the Management of Coastal Areas and Small Islands. The revision has changed the HP3 regime from Law 27/2007 to the licensing regime in Law 1/2014. Unfortunately, these changes would lead to various juridical problems ranging from conflict between the laws and regulations under legislation that ultimately is potentially detrimental to the constitutional rights of coastal communities. This research focuses on juridical and sociological aspects related to the coastal communities protection of constitutional rights after the Constitutional Court Decision Number 3/PUU-VIII/2010. This research in-depth discusses the follow-up of the Constitutional Court decision a quo by legislators, central government, local governments, stakeholders, and the fulfilment of the constitutional rights of coastal communities. This research is normative legal research by examining the Constitutional Court decision Number 3/PUU-VIII/2010. The descriptive discussion used to understand coastal zone management law's politics to fulfil the constitutional rights of coastal communities. Besides, integrated coastal zone management (Integrated Coastal Zone Management) is a dynamic process, multidisciplinary, and repeated to promote sustainable coastal areas' sustainable management. It includes the whole cycle of information collection, planning, decision-making, management, and implementation monitoring.

Coastal areas play a crucial role in maintaining the ecological balance of ecosystems and developing the social and economic wellbeing of the countries bordering it. However, the pressure on both terrestrial and marine resources, the use of oceans as a wastes deposit, the growth of population and the increasing of urbanization and human activities in coastal areas are all causes for marine and coastal degradation. The present situation constitutes a significant danger in many places. As an example, the pollution of the coastal waters in the Mediterranean has increased in recent years. Industrialization, tourism and ports activities along the coastline of the Mediterranean are the main sources of many pollutants that have effects on human’s health and environment. So that, it is very important to examine seawater quality in order to protect the marine and coastal areas from degradation. Hence, comes the need to consider a physicochemical and bacteriological study to evaluate the quality of Tangier coastal seawater using the Water Quality Index (WQI). A campaign of 25 sampling points was conducted and the results of the WQI calculation have highlighted the Tangier water was between medium and bad.

Abstract Amendments to Law no. 27 of 2007 became Law no. 1 of 2014 concerning the Management of Coastal Areas and Small Islands has an impact on the coastal and marine spatial planning process in every region, including Bangka Belitung. This planning process requires stakeholder collaboration to carry out broader cross-sectoral coordination. Apart from being composed of more than 80% of the water area, the struggle for access and conflicts over the use of marine space also take place in a vertical and horizontal level. The dilemma of authority between levels of government and law enforcement authorities, as well as between local governments, communities, and state corporations, is a form of hierarchical conflict. Conflicts between governments at the street bureaucracy (Village) level and their citizens, or friction between pro and contra groups against marine mining are examples of horizontal conflicts. The complexity of this problem has demanded the government to be presented in a more powerful and most decisive position in the management of the coastal and marine areas of Bangka Belitung so that it does not drag on. Therefore, the government needs to formulate comprehensive resource optimization options in the coastal and marine zones. This study aims to map how a collaborative approach in coastal and marine spatial planning through Regional Regulation (Perda) Number 3 of 2020 concerning the Zoning Plan for Coastal Areas and Small Islands of the Bangka Belitung Islands Province. At least 3 dominant actors are involved and collaborate, namely the government, fishermen, and investors.
