Abstract: China's Three Gorges Dam Project (TGP) is the world's largest hydroelectric power project, and as a consequence the reservoir area is at risk of ecological degradation. This study uses net primary productivity (NPP) as an important indicator of the reservoir ecosystem's productivity to estimate the impacts of the TGP in the local resettlement region of the Three Gorges Reservoir Area (TGRA) over the 2000-2010 period. The modeling method is based upon the Carnegie Ames Stanford Approach (CASA) terrestrial carbon model and uses Moderate Resolution Imaging Spectroradiometer (MODIS) remote sensing data for modeling simulation. The results demonstrate that total NPP in the resettlement region decreased by 8.0% (632.8Gg) from 2000 to 2010. The impact of the TGP on NPP is mainly mediated by land-use change brought about by the large-scale inundation of land and subsequent massive resettlement of both rural and urban residents. Nearby resettlement, land inundation, and relocation of old urban centers and affiliated urban dwellers are responsible for 54.3%, 28.0%, and 5.8% respectively of total NPP reduction in the resettlement region over the study period. The major national ecological projects implemented in the TGRA since 1998 have played a key role in offsetting the negative impacts of the TGP on NPP in the region.

Abstract: The total fertility rate of the Chinese population has declined dramatically over the last three decades. Research has substantiated the causal link between particulate matter (PM) and adverse health effects. However, the impact of PM on the birth intentions or fertility behavior of the childbearing population remains understudied. The paper analyzes the impact of PM2.5 concentration (a mixture of extremely small solid particles and liquid droplets found in the air) on the second birth intentions of the Chinese floating population. We used urban migrant population matching data at the prefectural level for the analysis. The unique datasets were derived from the Chinese Floating Population Dynamic Survey in 2014 administered by the National Health Commission, the National Prefecture-level City Matching Data administered by the National Bureau of Statistics of China, and the air pollution index PM2.5 collected by the Green Peace Organization. The results show that PM2.5 concentration has a negative impact on the second birth intentions of the floating population. This impact exhibits marked regional heterogeneity: the desire for a second birth across migrant groups living in south China decreases if PM2.5 concentration goes up, while migrants coming from, and living in, north China show strong intentions to have a second birth despite an increase in PM2.5 concentration in northern cities. The results have direct implications for the Chinese government at various levels to play a vital role in making and implementing environmental policies on the mitigation of smog to effectively safeguard the health of in iduals and communities and potentially raise China’s fertility rate.

Abstract: Natural capital (NC) is crucial to human existence and human well-being. Evaluating ecosystem services on a regional scale has presented tremendous theoretical, methodological and policy challenges. This study addresses the challenges by developing an interdisciplinary methodology, based on expert knowledge, and by focusing on the Yangtze River Delta of China. It evaluates the stock of NC, analyzes the characteristics of, and identifies the key drivers for, spatial and temporal change in NC in the deltaic region from 2000 to 2010. A main contribution is the novel incorporation of remote sensing data that explains the dynamics of the spatio-temporal change in land use and a set of ecosystem service indicators derived from it. The study focuses on key indicators for key ecosystem services related to carbon sequestration, grain production and water supply. The indictors reflect the spatial heterogeneity of NC across erse ecosystems in the region. Each indicator builds on land use configuration and land use composition information derived from 250 m 16-day MODIS and Landsat TM remote sensing data for 2000 and 2010, with adjustment parameters being constructed. The regional evaluation shows an overall degradation of ecosystem services, reducing total NC by 10.4% (or 8.44 billion yuan) in 2000-2010. The spatial distribution of NC exhibits a declining pattern from the south to the north of the delta. At the city level, 15 out of 16 major cities in the region have experienced dramatic loss of NC, and this pattern is significantly correlated with rapid urbanization, population growth and industrialization. Land use/land cover change and deteriorating water quality are dominant factors causing NC depletion, while increased grain productivity and environmental policies help offset the NC losses. Outcomes of this research are useful to policy makers to mitigate the declines in NC through balancing the growth between economy and population.

Abstract: While accepting that the migration–development nexus is best understood from a transnational perspective, recent studies analyse this nexus in a partial way rather than holistically. We review the literature, then attempt an enriched account of the complex and rapidly evolving relationship between diaspora and development in China – a country undergoing profound demographic, economic and social changes. Using in‐depth interviews with a variety of key informants or stakeholders and a transnationally oriented framework, we analyse features across three core policy dimensions that incorporate both international and domestic dynamics: citizenship, top talent recruitment and soft power. Our findings contribute to the literature on Chinese‐state‐diaspora relations. They show that China's approach to its diaspora policy and development, practice and outcomes reaches with powerful new effects across national borders. The transnational–relational perspective gives an optimal paradigm for researchers and policymakers to understand changing strengths and complexities in interactions (contestation, conflict, negotiation, cooperation) between multi‐scalar and multi‐dimensional linkages, and to form diaspora policy and engagement programmes responsive to unprecedented global political, economic and social disruption.

Abstract: Data on diasporas are incomplete, inaccurate, and beset by definitional fluidity as the concept itself evolves. Despite their significant role in homeland development, members of a diaspora population are typically passed over in origin countries’ censuses, and policies and planning rely instead on statistics generated in destination countries. To analyse the data available from destination countries, this article deploys two coordinated concepts—diaspora and transnationalism. We construct a demographic and socio‐economic profile of the Chinese diaspora population in Australia spanning 2000–2016. That work is based on the 2016 Australian Census and on Migrants Integrated Dataset (ACMID) and 2016 Australian Census and Temporary Entrants Integrated Dataset (ACTEID) micro‐files sourced from the Australian Bureau of Statistics. The profile is disaggregated by permanent or temporary residency status, visa, and citizenship, stratified by geographic distribution, and compared with that of Australia’s overall migrant population. Nuanced understandings of the size, composition, distribution, and socio‐economic integration into the destination lays a baseline necessary for policymakers and agencies in the countries of origin as they work toward more targeted diaspora engagement practices. Those understandings also inform retention strategies in Australia concerning diaspora groups that can enhance economic and social inclusion.

Abstract: Spatial and temporal change in soil erosion in the Three Gorges Reservoir area since the water storage of the reservoir began filling to 135 m in 2003 is poorly understood. Using a modified soil erosion model, this study quantifies and analyses change in the extent and intensity of soil erosion in the region from 2000 to 2008. MODIS-NDVI remote sensing data (with 250 m spatial resolution) are used in the modelling and analysis of the study. The total amount, area, and intensity of soil erosion in the reservoir region presented a declining trend from 2000 to 2008. Yet there was an anomaly in the trend, in which extreme soil erosion occurred in 2003 and lasted until 2005. The average volume of soil erosion per year decreased by 4.10 × 106 t and the mean area of land experiencing soil erosion reduced by 1129.6 km2 from the pre-storage period (2000–02) to post-storage period II (2006–08). Land suffering soil erosion at high, very high, and severe levels mainly comprises forest and cropland on slopes with gradients ≥15° and is largely distributed in the eastern and south-western sections of the reservoir area. Land experiencing soil erosion at slight or moderate levels mainly involves cropland and forest on slopes with gradients ≥10° in the central section of the reservoir area. The impact of the Three Gorges Project on soil erosion since 2000 has been mainly mediated through three mechanisms: near-resettlement of rural and urban people increased frequency and severity of geological hazards induced by rising storage of the reservoir and implementation of ecological projects in the region. Through the former two mechanisms, soil erosion in the affected communities has been exacerbated, while the ongoing ecological projects appear to offset both the extent and intensity of soil erosion in the reservoir region. Other important factors influencing soil erosion include urban reconstruction and expansion, varying intensity of precipitation, and soil degradation.

Abstract: Livelihood recovery is a top priority to sustain resettled communities. The purpose of this paper is to assess livelihood vulnerability of those displaced and resettled in the aftermath of the 2008 Wenchuan earthquake, China, based on a newly constructed locational adjustable framework. The study takes two resettlement villages in Sichuan Province as case study areas. Face-to-face surveys using a structured questionnaire and semi-structured in-depth interviews were conducted to collect primary data in 2012-2013. The findings show that distant resettlement of people post the Wenchuan earthquake has resulted in an increased livelihood vulnerability within resettlers and that they face more hazards post-resettlement when compared to host residents in the resettlement areas. The indicators considered for the livelihood vulnerability index (LVI) are only a subset that represents typical factors applicable in the context of rural settings of China. The LVI may vary if more indicators are incorporated or coefficients obtained using different methods. Highlights should be placed on livelihood assets and hazards to livelihood of the displaced people. During the transition period there is a pressing need for greater efforts to enhance migrants’ employment skills and assist them to restore viable livelihood activities. This paper constructs a locational adjustable framework for analyzing and assessing livelihood vulnerability of disaster-induced resettlers from three aspects: livelihood hazards, livelihood assets and coping strategies.
