“…2), but many have been displaced into growing urban centers such as Chongqing. Estimates for population displacement from the Three Gorges Dam vary widely, but at least 1 million people have already been relocated (Cernea, 2003;Sleigh, 2006;Li et al, 2007). Recently the Chinese government has suggested that perhaps as many as 4 million will ultimately be relocated, which constitutes a quarter of the population living in the reservoir area (Stone, 2008).…”

“…With some notable exceptions (e.g., Jobin, 1999;Sleigh et al, 2006;Li et al, 2007), research programs and efforts on the Three Gorges Dam and human health exist in disparate spheres, resulting in a fragmented approach to what is essentially a linked human-environment system. Although reductionist approaches are necessary, there also is a need for integrative science to more appropriately inform policy.…”

“…Impoundment and hydrological alterations are expected to increase the range of Oncomelania snails, the host vector for Asian schistosomiasis, and the disease transmission rates (Maszle et al, 1998;Xu et al, 1999bXu et al, , 2000Li et al, 2000;Li et al, 2007;Zheng et al, 2002). The increase in vector habitat, however, may be less of a threat than the increased exposure related to the relocation of thousands of people and their ruminant livestock (Jackson and Sleigh, 2000;Li et al, 2007). Relocation effects include increased human habitation and population density in marginal agrarian environments where people access vector habitats for subsistence activities (fishing, farming, etc.)…”

Toward Holistic Evaluation and Assessment: Linking Ecosystems and Human Well-Being for the Three Gorges Dam

A significant challenge exists in assessing the social and ecological impacts of development projects in a holistic and comprehensive manner. Our objective is to elucidate the linkages between ecological change and human well-being, and its importance in integrated assessment policy for development projects, using the Three Gorges Dam (China) as a case study. A collaborative research initiative was undertaken to review and synthesize published information on the ecological and human health effects of the Three Gorges Dam. Our synthesis suggests that the Three Gorges Dam has altered social-ecological dynamics of human health and ecosystem function in the Yangtze River basin with significant consequences for human well-being. Direct impacts to human well-being were grouped into four primary categories, including: (1) toxicological impacts; (2) shifting infectious disease dynamics; (3) natural hazards; and (4) social health. Social-ecological relationships were altered in complex ways, with both direct and indirect effects, positive and negative interactions, and chronic and acute impacts on human well-being. Our synthesis supports a comprehensive evaluation of development projects via integrated assessments of human and environmental consequences. This is probably best achieved through a coupled social-environmental impact assessment to ensure holistic and comprehensive analyses of expected costs and benefits. The role of research can thereby be to elucidate the linkages between ecosystems and human health to better inform the assessment process. A synthesis of the existing information on the Three Gorges suggests that this is best achieved through institutional collaboration and transdisciplinary integration of expertise.

“…Moreover, schistosomiasis infection is transmitted through humans and other mammalian hosts that contact cercariae released by snails when they are exposed to infested water (Li et al 2007). The Dongting Lake region, which is located in the middle and lower reaches of the Yangtze River, is one of the major and typical lake and marshland areas in China where schistosomiasis is endemic (Yu et al 2002;McManus et al 2011).…”

Schistosomiasis is a severe public health problem in the Dongting Lake region, and its distribution, prevalence, and intensity of infection are particularly sensitive to environmental changes. In this study, the human and bovine schistosomiasis variations in the Dongting Lake region were studied from 1996 to 2010, and the relationships between schistosomiasis and water level were examined. Furthermore, based on these results, the potential effects of the Three Gorges Dam (TGD) on schistosomiasis were investigated. Results showed an increase in human schistosomiasis and in the scope of seriously affected regions, along with a decrease in bovine schistosomiasis. Human schistosomiasis was negatively correlated with water level during wet season (from May to October), particularly the average water level in October. This finding indicated that the decreasing water level may be highly related to the increasing of human schistosomiasis in the Dongting Lake region. Based on this result and the variation of schistosomiasis before and after the construction and operation of TGD, the impoundment of the Three Gorges reservoir is believed to decrease the water level and increase the contact between people and schistosomiasis. Therefore, the TGD, which is operated by regulating water and scheduling water operations, is not good for the control of human schistosomiasis in the Dongting Lake region. Although the extent of the influence of the TGD on schistosomiasis remains unclear, the influence of the TGD on preventing and controlling schistosomiasis should not be ignored.

Spatial and temporal characteristics of 2H and 18O in the basin of Dongting Lake: impact of monsoon precipitation

Two water sampling campaigns were carried out in April and August 2012 to investigate the spatial and temporal characteristics of 2 H and 18 O in the basin of Dongting Lake and to further understand the interactions between precipitation, river water, lake water, and groundwater. Influenced by different monsoons, precipitation, river water, and lake water are enriched in isotopes in April but depleted in August. Stable isotopes of river water and lake water also have great spatial variations. Unlike river and lake water, groundwater has little seasonal isotopic variation, indicating that the transformation between surface water and groundwater is very slow.
