“…En Centro América se elevó por arriba del 90 %, ya que es una tecnología madura y de larga duración, con algunas centrales en operación que tienen más de 100 años[2].Por otra parte, lasáreas de preocupación para los temas ambientales y sociales se relacionan por la falta de medidas de mitigación, indemnizaciones adecuadas, seguimiento y acumulación de impactos. Asimismo, en el desarrollo exitoso de un proyecto hidroeléctrico se debe reconocer la importancia en la atención de los derechos humanos[2]; en ese sentido,[3] consideran como un punto de partida para el desarrollo de la energía hidroeléctrica sustentable, la gestión integrada de recursos hidráulicos enfocados al conocimiento y racionalización del aprovechamiento de los recursos de las cuencas, además de la planeación en su desarrollo a fin de reducir su impacto. Por esta vía, la sustentabilidad hidroeléctrica está formada por tres componentes fundamentales:• La viabilidad a largo plazo del proyecto hidroeléctrico.• La contribución del proyecto al desarrollo sustentable.• La integración de las diferentes perspectivas de la sustentabilidad (ambiental, social, económica, financiera, técnica y gobernanza).INGENIERÍA • VOL.…”

Context: Hydroelectric is a mature and long-lasting technology, but it has presented environmental and social problems. To address these problems, hydroelectric sustainability initiatives have been created for more than two decades. In Mexico, hydroelectric projects present environmental and social problems that cause delays in their construction or delays in their entry into operation. The objective of this study was to define the weightings of the criteria of hydroelectric sustainability through multicriteria decision making methods to a group of experts.Method: Through the combination of the multicriteria Analytical Hierarchical Process and the Programming of Goals the opinion of a group of experts was obtained in the planning of hydroelectric projects.Results: Once the AHP-GP methods were applied to determine the weighting of the hydroelectric sustainability perspectives, it was found that the weights closest to the opinion of all the groups are those issued by the group of governance experts. Conclusions:The results indicate that, when questioning a heterogeneous group of experts, it was observed that significant agreements are presented between the groups, which is noteworthy because they are groups of experts that have different specialties.

“…Sustainable development has a long-standing history, developed by a variety of disciplines. Since the 1972 UN Conference on the Environment, Stockholm, the meaning of "sustainable development" has evolved with emphasis was on "slow down growth and protect the environment" (ecodevelopment) [1]. The term sustainable development was coined for the first time in an international document World Conservation Strategy, published by the International Union for the Conservation of Natural Resources in 1980 [2].…”

“…Commonly known as the Brundtland Report, it defines sustainable development as, "development that meets the needs of the present generation without compromising the ability of the future generation to meet their own needs" [5][6][7][8]. From Stockholm to WCED (1972)(1973)(1974)(1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987), sustainability discussion was mainly by the scientific community and NGOs and defined merely by any economic development conducted without the depletion of natural resources [1]. In 1992 and 2002, the Earth Summit, Rio, and World Summit on Sustainable Development, Johannesburg, were major events that continued the discussions on sustainable development [1,8].…”

Sustainable Hydroelectric Dam Management in the Context of Climate Change: Case of the Taabo Dam in Côte D’Ivoire, West Africa

et al. 2019

Management of hydroelectric dams is an aspect of sustainability that comes with resolving problems locally. The use of global indicators has not been a sustainable solution, thus the need for local indicators. Besides, current sustainability assessment tools lack the integration of climate, making assessments in a climate change context impossible. In this paper, we present management and sustainability assessment in a climate change context using sustainability indicators. We modeled a change in the climate using normal, moderate, and extreme climate conditions defined by Standardized Precipitation Indices (SPI) values. Out of 36 years analyzed, 24 years fall in the near-normal climate regime, and the remaining 12 years in moderate and extreme conditions, making near-normal climate regime the basis for managing the Taabo Dam. The impact of climate, techno-economic, and socio-environmental indicators on sustainability were investigated, and the results were analyzed according to scenarios. Climate adaptation shows higher sustainability indices than techno-economic and socio-environmental scenarios. Probability matrices show high and low values, respectively, for environmental and flooding indicators. Risk matrices, on the other hand, show that even with small probability values, risks still exist, and such small probabilities should not be taken as an absence of risk. The study reveals that sustainability can be improved by integrating climate into existing assessment methods.

“…Energy policymaking, however, is interwoven with social, economic, environmental, technical, and national issues [1][2][3], which represent conflicting demands. Sustainable energy policy integrates the social, economic, environmental and technical issues for a common energy development goal [4,5]. The sustainability of an energy system is, therefore, judged by its ability to meet strict social, economic, environmental, and technical criteria [6,7].…”

Sustainability Assessment of the Bui Hydropower System

et al. 2017

Sustainable hydroelectric projects are judged by their contribution to sustainable development, long-term viability, and ability to integrate sustainability goals. This paper analyses the Bui hydroelectric dam in Ghana vis-à-vis these expectations using sustainability indices. A multi-criteria analysis tool, APIS (Aggregated Preference Indices System), is used to build indices for Bui dam for four hydrologic seasons. An analysis of the indicators used revealed that environmental indicators are weightiest and economic indicators have the least weight. Comparative analysis of the Bui dam project shows 40%, 36%, 18%, and 6% priority for technical, economic, social, and environmental criteria, respectively, during its implementation stages. Per estimation of this work, the general sustainability index of the Bui dam is between 0.4 and 0.6 on a scale of 0 to 1. The impact of seasonal climate change will reduce the index to below 0.5 for three hydrologic seasons. The results show that Bui dam has an average but weak index of sustainability. Multi-criteria analysis offers quality assessment of energy projects, which is valuable for analyzing proposed or existing energy projects. This paper shows the possibility of using multi-criteria analysis approach to assess the sustainability of a hydroelectric dam. The approach offers a quantitative and qualitative assessment of a hydroelectric dam via a suitable choice of indicators.
