CSR and the environment: business supply chain partnerships in Hong Kong and PRDR, China

CORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 5 2009
Dennis K. K. Cheung
Abstract Cross-border relocation of the production lines of Hong Kong companies to the Pearl River Delta Region (PRDR) of China relocates the pollution source geographically. In contextualizing corporate social responsibility (CSR), more and better collaborations on environmental management between Hong-Kong-based companies and their supply chains within Hong Kong and the PRDR are needed. Using a qualitative approach, this research identifies and examines nine concerned business supply chain partnership cases. Stakeholders perceived that partnership is a good tool for improving corporate environmental management. However, although it has become more active since 2002, partnership is not yet popular. More time and support are needed to develop it. Businesses should take further steps to benefit themselves and the environment. Based on the first-hand experiences and opinions of interviewees, this paper analyzes and presents recent partnership activities; their drivers and barriers; factors in their successes; and the possible roles of government and business associations in fostering partnership development.

Local Capitalisms, Local Citizenship and Translocality: Rescaling from Below in the Pearl River Delta Region, China

INTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 2 2007
ALAN SMART
Abstract Chinese economic reforms have profoundly changed the scale at which things get done. Much of the existing literature on scale has concentrated on the politics of rescaling from above. Less has been written about rescaling initiatives from below, the focus of this study. It distinguishes three important localisms. Local capitalisms treats capitalism as subordinate to local social and political processes that provide crucial conditions of existence. Local citizenship sees processes of entitlement and exclusion as accomplished locally rather than through national frameworks. Translocality describes the ways in which claims are made on the loyalties of those possessing capital but residing elsewhere and the promotion of the place through image-building and physical/social infrastructural enhancements. These three distinct localisms overlap and interact in a variety of ways to shape a new social and spatial order in post-reform China. A detailed study of the practices of localism in the Dongguan city-region reveals the ways in which the emergence of capitalism has been dependent on pre-existing social connections and based on villages and townships. The entitlements of citizenship are polarized between the local hukou population and the migrant workers irrespective of the national definition of social safety net and regardless of the physical presence of the individuals. Résumé En Chine, les réformes économiques ont profondément modifié l'échelon auquel les choses se font. Les publications traitant de cet aspect se consacrent en général aux politiques de redimensionnement venues des instances supérieures, et abordent plus rarement les initiatives venues d'en bas, objets de cette étude. Cette dernière distingue trois localismes importants: les capitalismes locaux, le capitalisme apparaissant subordonné aux processus sociaux et politiques locaux qui déterminent les conditions d'existence; la citoyenneté locale pour qui les processus d'habilitation et d'exclusion s'effectuent au plan local et non en fonction de cadres nationaux; la translocalité qui décrit comment est sollicitée la loyauté de ceux qui possèdent le capital mais résident ailleurs, et comment des projets de création d'image et d'infrastructure matérielle ou sociale dynamisent la promotion du lieu. Ces trois localismes se chevauchent et interagissent diversement, façonnant un nouvel ordre social et spatial dans la Chine de l'après-réforme. Une étude détaillée du localisme pratiqué dans la ville de Dongguan fait apparaître les modalités d'un capitalisme émergent, dépendant des liens sociaux existants et basé sur des villages ou municipalités. L'accès à la citoyenneté définit un clivage entre la population locale ayant son hukou et les travailleurs migrants, indépendamment de la notion nationale de filet de protection sociale ou de la présence physique des individus.

Distribution of polycyclic aromatic hydrocarbons in particle-size separates and density fractions of typical agricultural soils in the Yangtze River Delta, east China

EUROPEAN JOURNAL OF SOIL SCIENCE, Issue 6 2008
J. Z. Ni
Summary Soil organic matter can be divided into different organic carbon (C) pools with different turnover rates. The organic pollutants in soils associated with these organic C pools may have different bioavailability and environmental risks during the decomposition of soil organic matter. We studied the distribution patterns of 15 USEPA priority polycyclic aromatic hydrocarbons (PAHs) in different particle-size separates (clay, fine silt, coarse silt, fine sand and coarse sand) and density fractions (light and heavy fractions) of nine agricultural topsoils (0,20 cm depth) from a contaminated area in the Yangtze River Delta region of east China. There was a decreasing trend in PAH concentration in particle-size separates with decreasing particle size. However, the different particle-size separates had similar PAH composition. The concentration of PAHs in the light fraction ranged from 13 037 to 107 299 ,g kg,1, far higher than in the heavy fraction, which ranged from 222 to 298 ,g kg,1. Although the light fraction accounted for only 0.4,2.3% of the soils, it was associated with 31.5,69.5% of soil PAHs. The organic matter in coarse silt had the strongest capacity for enrichment with PAHs. Combining the distributions of PAHs and the turnover rates of organic matter in different soil fractions, the environmental risks of PAH-polluted soils may be due mainly to the PAHs associated with sand and the light fraction.

Effects of urbanization on the land sea breeze circulation over the Pearl River Delta region in winter

INTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 7 2010

Abstract In this study, the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Model (MM5) was used to investigate the effects of urbanization on land,sea breezes (LSBs) in the Pearl River Delta (PRD) region, which is a rapidly developing area located in southern China. LSBs in the 2003/2004 winter were simulated utilizing an approach in which the NCEP Final Analysis data averaged in the 2003/2004 winter is used as initial and lateral boundary conditions for the model. The simulated surface winds are shown to be capable of reproducing the basic features and diurnal variation of the LSBs. Sensitivity experiments with changes in land uses were performed with this model. Results of these experiments show that urbanization in the PRD region can have significant effects on the patterns of the LSBs and circulation in the region. In particular, it has been shown that the urbanization of Shenzhen (a major city located in the eastern coast of the PRD and neighbouring to the north of Hong Kong) may significantly enhance the sea breeze to the west of Hong Kong in the early afternoon. This may enhance the low-level convergence in Hong Kong and may worsen the air pollution problem there. On the other hand, the effects of urbanization in the western coast of the PRD region are relatively local and LSBs on the eastern PRD are generally not affected.

Inbreeding from isonymy and repeated pairs of surnames in the Ebro Delta region (Tarragona, Spain)

AMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 6 2006
Mireia Esparza
The aim of the study was to evaluate the levels of inbreeding calculated from isonymy with its random (Fr) and nonrandom (Fn) components, and repeated pairs of surnames (RP2) and their random component (RP2r) in the Ebro River Delta region (Tarragona, Spain). This region is made up of four parishes, and data correspond to the period 1939,1995. The global results are on the same levels as observed in other studies, but the values obtained in 3 of 4 parishes are relatively high. The Fn global value is higher than Fr, as opposed to what happens in each parish, so there is a clear Wahlund effect of subdivision of the region into parishes. Among the parishes there is a clear differentiation for Amposta, with values much lower than for the rest, due to the behavior of this population, i.e., a high immigration rate. Am. J. Hum.
