Received: 28 December 2018; Accepted: 5 March 2019; Published: 8 March 2019 Abstract: Both Southern Italy and Central China feature historic rural settlements characterized by underground constructions with residential and service functions. Many of these areas are currently tackling economic, social and environmental problems, resulting in unemployment, disengagement, depopulation, marginalization or loss of cultural and biological diversity. Both in Europe and in China, policies for rural development address three core areas of intervention: agricultural competitiveness, environmental protection and the promotion of rural amenities through strengthening and diversifying the economic base of rural communities. The challenge is to create innovative pathways for regeneration based on raising awareness to inspire local rural communities to develop alternative actions to reduce poverty while preserving the unique aspects of their local environment and culture. In this view, cultural heritage can be a catalyst for the sustainable growth of the rural community.

  • Violence and Predation, Mainly in the Form of Piracy, Were Two Of
    violence and predation robert j. antony Violence and Predation on the Sino-Vietnamese Maritime Frontier, 1450–1850 iolence and predation, mainly in the form of piracy, were two of V the most persistent and pervasive features of the Sino-Vietnamese maritime frontier between the mid-fifteenth and mid-nineteenth cen- turies.1 In the Gulf of Tonkin, which is the focus of this article, piracy was, in fact, an intrinsic feature of this sea frontier and a dynamic and significant force in the region’s economic, social, and cultural devel- opment. My approach, what scholars call history from the bottom up, places pirates, not the state, at center stage, recognizing their impor- tance and agency as historical actors. My research is based on various types of written history, including Qing archives, the Veritable Records of Vietnam and China, local Chinese gazetteers, and travel accounts; I also bring in my own fieldwork in the gulf region conducted over the past six years. The article is divided into three sections: first, I discuss the geopolitical characteristics of this maritime frontier as a background to our understanding of piracy in the region; second, I consider the socio-cultural aspects of the gulf region, especially the underclass who engaged in clandestine activities as a part of their daily lives; and third, I analyze five specific episodes of piracy in the Gulf of Tonkin. The Gulf of Tonkin (often referred to here simply as the gulf), which is tucked away in the northwestern corner of the South China Sea, borders on Vietnam in the west and China in the north and east.

At present, relevant studies either depend on the use of other auxiliary data (such as field water depths or water column data) or contain too many unknown variables, thus making these studies suitable only for images that contain enough visible wavebands. To solve this problem, a Quasi-Analytical Algorithm (QAA) approach is proposed in this paper for estimating the water depths around Weizhou Island by developing a QAA to estimate the diffuse attenuation coefficients and simplifying the parameterization of the bathymetric model. The approach contains an initialization sub-approach and a novel global adjustment sub-approach. It is not only independent of other auxiliary data but also greatly reduces the number of unknowns.

  • Inventory of Environmental Work in China
    INVENTORY OF ENVIRONMENTAL WORK IN CHINA In this fifth issue of the China Environment Series, the Inventory of Environmental Work in China has been updated and we made extra effort to add many new groups, especially in the Chinese organization section. To better highlight the growing number of U.S. universities and professional associations active in China we have created a separate section. In the past inventories we have gathered information from U.S. government agencies; from this year forward we will be inventorying the work done by other governments as well. This inventory aims to paint a clearer picture of the patterns of aid and investment in environmental protection and energy-efficiency projects in the People’s Republic of China. We highlight a total of 118 organizations and agencies in this inventory and provide information on 359 projects. The five categories of the inventory are listed below: Part I (p. 138): United States Government Activities (15 agencies/organizations, 103 projects) Part II (p. 163): U.S. and International NGO Activities (33 organizations, 91 projects) Part III (p. 190): U.S. Universities and Professional Association Activities (9 institutions, 27 projects) Part IV (p. 196): Chinese and Hong Kong NGO and GONGO Activities (50 organizations, 61 projects) Part V (p. 212): Bilateral Government Activities (11 agencies/organizations, 77 projects) Since we have expanded the inventory, even more people than last year contributed to the creation of this inventory. We are grateful to all of those in U.S. government agencies, international and Chinese nongovernmental organizations, universities, as well as representatives in foreign embassies who generously gave their time to compile and summarize the information their organizations and agencies undertake in China.

We analyze precipitation data from 47 meteorological stations spanning between 1961 and 2012 and NCEP/NCAR reanalysis to understand spatiotemporal variability and change of spring precipitation of South China and their relations to atmospheric circulations. Empirical orthogonal function (EOF) analysis and rotated EOF (REOF) are used to reveal dominant spatial structures of precipitation anomaly and Mann-Kendall testing method to determine the temporal locations of abrupt changes during the analyzed time span. We find that the first spatial mode of the spring precipitation of the South China has a domain uniform structure; the second is dominated by a spatial dipole; and the third contains six variability centers.

The observations reveal that Qiongzhou Strait is an area where opposing tidal waves interact and a source of water transport to the Gulf of Beibu (Gulf of Tonkin), SCS. A year-round westward mean ¯ow with a maximum speed of 10±40 cm s 21 is found in Qiongzhou Strait. This accounts for water transport of 0.2±0.4 Sv and 0.1±0.2 Sv into the Gulf of Beibu in winter±spring and summer±autumn, respectively. The out¯ow from Qiongzhou Strait may cause up to 44% of the gulf water to be refreshed each season, suggesting that it has a signi®cant impact on the seasonal circulation in the Gulf of Beibu.
