“…At the same time, there is a global will to shift the energy generation dependence from fossil fuels to renewable energy sources such as solar, wind, and hydropower [2][3][4]. This is in line with the current global move to fight climate change by promoting the energy production through low-carbon combustion-free energy sources (LCCF) [5]. The utilization of LCCF energy sources has seen continuous growth, at least within the 21st century and is projected to grow further in the coming years [6].…”

An investigation is conducted on the Francis turbine’s cavitation characteristics and its influence on system hydraulic stability using two experimental methods, namely the flow visualization and acoustic emission methods. The investigated turbine is of Francis type with a 15-blade runner and has a specific speed of 202 rpm and a rated head of 30 m. Having tested the machine under a wide range of cavitation conditions, the gap cavitation is the earliest to develop as the cavitation coefficient gradually decreases and has no obvious effect on the machine’s external performance characteristics. The airfoil cavitation follows and causes the increase and decrease in machine flow rate and head, respectively, showing its drag reduction effect, where, at the same time, the pressure pulsation amplitude gets to its peak value. There is also the formation of constant cavitation zones and the involvement of an unsteady surge close to the wall of the draft tube’s cone. Pushing the cavitation coefficient to even lower values, there is the formation of an annular cavitation zone, accompanied by a sharp drop in cone pressure pulsation amplitudes while the former drag reduction effect disappears. The trend of noise is basically the same as that of pressure fluctuation, which confirms its trustworthiness when it comes to cavitation occurrence detection within Francis turbines.

“…Such approach has been narrowly related to energy efficiency, energy sovereignty and security, energy matrix diversification, and the reduction of oil dependency and hence greenhouse gas emissions (MEER 2012). Nonetheless, the link between hydropower generation, reservoir' greenhouse gases emissions, climate change, ecosystem services, biodiversity, human wellbeing, socio-ecological conflicts and environmental sustainability has been ultimately overlooked for the sake of sustainable development and economic growth (Fearnside 2014;Hess and Fenrich 2017;Briones-Hidrovo, Uche, and Martínez-gracia 2021;Gasparatos et al 2017;Mendieta-Vicuña and Esparcia 2022). It should bear in mind that BAU-HPO has been aligned with regulations of the United Nations Framework Convention on Climate Change, the Kyoto Protocol's Clean Development Mechanism (CDM), according to which carbon credit is granted to hydropower projects (Fearnside 2013;MEER 2012;Fearnside 2015b).…”

Hydropower policy in Ecuador: An analysis from environmental perspective and recommendations for future policymaking.Renewable energies are vital to tackle climate change and reduce environmental issues. In this sense, hydropower plays a key role. Broadly speaking, hydropower is perceived as a climate ally and considered environmentally sustainable.However, its development is still controversial due to the well-known environmental and ecological impacts that put its environmental sustainability in question. In this sense, this study aims to analyze and discuss hydropower development and policy in Ecuador from an environmental perspective. The analysis addresses the research question of to what extent the business-as-usual hydropower policy is compatible and consistent with national environmental sustainability and Buen Vivir (Good Living) goals. For such purpose, the analysis is conducted by applying a proposed conceptual framework composed of critical elements such as Buen Vivir principles, rights of nature and the evidence on the environmental sustainability of hydropower. The analysis highlights the main environmental drawbacks of the BAU-HP policy and finds that the current development and policy of hydropower is ultimately detrimental to achieving national environmental sustainability and Buen Vivir. Moreover, it easily infringes the Rights of Nature and conflicts with the conservation of ecosystems and biodiversity. Following the findings, several environmental sustainabilityoriented recommendations are suggested for future hydropower policymaking.

“…Since 2018, West Java Provincial Government has also arranged a plan to revitalize Situ Rawa Kalong as a tourism area. Situ Rawa Kalong, one of the water resources also has a significant role in reducing the climate crisis, and achieving environmental sustainability [3]. For reaching sustainability, the water quality and biophysical conditions of Situ Rawa Kalong are the main components that have been analyzed.…”

Having a role as the water resource, situ water quality and biophysical conditions are the main components that reach the basis of sustainability analysis. This study aims to analyze the water quality and biophysical conditions of the Situ Rawa Kalong area as the basis for achieving sustainable management. The description of existing and potential conditions uses descriptive qualitative methods and scoring to measure the factors of water quality, lake quality, and tourism suitability. The literature study used secondary data from The Sanitation and Environmental Office of Depok City in the form of the Situ Rawa Kalong water quality data 2016-2020 and other sources. A field survey was conducted by measuring, mapping with GIS, and documenting. It concerns such data on vegetation, fauna, hydrology, morphology, climate, carrying capacity, topography, facilities, and infrastructure. The result is that Situ Rawa Kalong has limitations in determining the type of recreation. It is a non-contact and a view recreation. The types of tourism are meant for boating, fishing, and scenery recreation. The general biophysical condition of Situ Rawa Kalong is disturbed. As a potential water resource and tourism in Depok, Situ Rawa Kalong must be managed sustainability.
