valuing the effects of Hydropower Development on watershed ecosystem services case studies in the jiulong river watershed fujian province china
Estuarine Coastal and Shelf Science, 2010Co-Authors: Guihua Wang, Qinhua Fang, Luoping Zhang, Weiqi Chen, Zhenming Chen, Huasheng HongAbstract:Abstract Hydropower Development brings many negative impacts on watershed ecosystems which are not fully integrated into current decision-making largely because in practice few accept the cost and benefit beyond market. In this paper, a framework was proposed to valuate the effects on watershed ecosystem services caused by Hydropower Development. Watershed ecosystem services were classified into four categories of provisioning, regulating, cultural and supporting services; then effects on watershed ecosystem services caused by Hydropower Development were identified to 21 indicators. Thereafter various evaluation techniques including the market value method, opportunity cost approach, project restoration method, travel cost method, and contingent valuation method were determined and the models were developed to valuate these indicators reflecting specific watershed ecosystem services. This approach was applied to three representative Hydropower projects (Daguan, Xizaikou and Tiangong) of Jiulong River Watershed in southeast China. It was concluded that for Hydropower Development: (1) the value ratio of negative impacts to positive benefits ranges from 64.09% to 91.18%, indicating that the negative impacts of Hydropower Development should be critically studied during its environmental administration process; (2) the biodiversity loss and water quality degradation (together accounting for 80–94%) are the major negative impacts on watershed ecosystem services; (3) the average environmental cost per unit of electricity is up to 0.206 Yuan/kW h, which is about three quarters of its on-grid power tariff; and (4) the current water resource fee accounts for only about 4% of its negative impacts value, therefore a new compensatory method by paying for ecosystem services is necessary for sustainable Hydropower Development. These findings provide a clear picture of both positive and negative effects of Hydropower Development for decision-makers in the monetary term, and also provide a basis for further design of environmental instrument such as payment for watershed ecosystem services.

Evaluation of Hydropower Development on river ecosystem services
Ecology and the Environment, 2006Co-Authors: Mo Chuang-rongAbstract:A river provides mankind multifarious ecosystem services.It has great significance to evaluate the effects of Hydropower Development on river ecosystem services.This paper puts forward a method of “flow measurement” to evaluate the value of river ecosystem services,and the Development of Guangdong Heyuan Fengguang Hydro Project is taken as a case of quantitative analysis.Based on the classification of river ecosystem services and according to the actual situations and characteristics of river ecosystem services influenced by Hydropower Development,this paper selects appropriate approaches and parameters to calculate the changes of ecosystem service value caused by Hydropower Development.The results of the case study show that,the positive benefit of Feng-guang Hydro Project on river ecosystem services is 76.76 million yuan per annum,the negative benefit is-38.94 million yuan per annum.In addition,the negative benefit of the hydro project accounts for more than a half of the positive benefit,which makes it clear that the negative effects of the hydro project on river ecosystem services should not be neglected and appropriate ecological compensation measures should be adopted.

Evaluation of Hydropower Development on River Ecosystem Services
2005Co-Authors: Mo Chuang-rongAbstract:The influences of Hydropower Development on rivers ecosystem services are complex and omnifarious. This paper puts forward a method of calculating "flow" to evaluate the value of rivers ecosystem services, and taking the Development of Guangdong Zijin Likou Water Power Station as a case, quantitatively analyzes and evaluates the changes of rivers ecosystem service value after the projects operation.

Environment Management of Hydropower Development: A Case Study
Energies, 2021Co-Authors: Yakun Zhang, Wenzhe Tang, Colin Duffield, Lihai Zhang, Felix Kin Peng HuiAbstract:Environment management is one of the key aspects of Hydropower Development in acquiring sustainable energy. However, there has been limited research demonstrating the overall aspects of environment management of Hydropower Development with support of sound empirical evidence. In present study, the status of environment management in Hydropower Development was comprehensively investigated by conducting a case study based on the data collected from a field survey. The results show that, as environment management is largely subject to legal requirements, the environment management system needs to be established by integrating the legal requirements and needs of project implementation. This could potentially reduce the influence of legal restrictions on Hydropower Development. The main Hydropower project environment management processes include identifying key environmental factors, implementation, monitoring, and performance measurement, which deal with environmental issues such as terrestrial and aquatic ecology protection, wastewater treatment, solid waste disposal, and acoustic-environment protection. Project participants should establish partnering relationships to cooperatively deal with environmental impacts of Hydropower project Development, in which public participation and sufficient resources input into environmental protection are essential for project success. The results of this study provide a sound basis for participants to deal with the key issues of environmental protection such as meeting legal requirements, training for improving environment management process, cost control, and cooperative environment management. The results of this study could help practitioners to tackle the interactions among project delivery, environmental protection, and engagement of local communities in an optimized way with the aim of maximizing effectiveness of the resources of all participants.

Risk management of Hydropower Development in China
Energy, 2013Co-Authors: Wenzhe Tang, Maoshan Qiang, Shuli WangAbstract:There is a rapidly increasing demand for Hydropower in China. However, little research has been conducted to systematically investigate the overall aspects of Hydropower Development risks. With support of the data collected from a fieldwork survey, this study reports the multiple facets of Hydropower Development risks in China as perceived by main project participants. All groups have a common view on the criticality of safety, and the groups also have their own priorities, i.e., resettlement of migrants, incompetence of subcontractors, project delay, inadequate or incorrect design, premature failure of facilities and ecological and environmental impacts are the key risks to clients, whereas quality of work, financial related risks, reputation, and claims and disputes are the main concerns to contractors. A case study of Three Gorges Project further demonstrates that, Hydropower Development risks can be effectively managed by encouraging joint efforts of all participants to achieve the goals on producing renewable energy, reducing emissions of CO2, and providing important social/economical benefits. Future Hydropower Development should emphasize the interactions between project delivery, environmental, and economical processes to reach appropriate trade-offs among involving stakeholders, by adequately considering the inter-relations between project participants' risks as well as Hydropower project's externalities on a broad view.

Study on Capabilities of Hydropower Development Project
Applied Mechanics and Materials, 2012Co-Authors: Jia Ning Wang, Wenzhe Tang, Yong Mei ShenAbstract:The competence model is commonly used for study of an enterprise’s capabilities related to performance in the specific background. However, there is no analysis on capability index system and project performance indicator system of owners as large Hydropower Development enterprises in the former studies on the competence-based organizational capacity. In this paper, the owner’s capability index system related to the performance is put forth by studying the capability factors of a large Hydropower Development enterprise, and verified in our analyses on them. So, the constituent elements of the owner’s capability can be revealed.
