“…Large hydropower plants, typically more than 10 GW, with a reservoir have advantages associated with their multi-functional uses, including energy production, employment opportunities, effective water handling and control, as well as stabilization of the electric network due to its versatile operating condition. In contrast to small hydropower, which is generally constructed for local development, decentralized energy generation, and investment opportunities in distant regions [51]. Malaysia is enriched with the goodness of water supplies with a total of 200 rivers in the country.…”

The aim of this study is to investigate the impact of the construction industry on the environment in Malaysia and propose strategies for mitigating its adverse effects through the adoption of sustainable building techniques. The study recognizes the importance of a healthy ecosystem in promoting health conditions, improving living standards, and ensuring a sustainable future for the nation. However, the recent population expansion has placed increased pressure on Malaysia's building industry and infrastructure, resulting in environmental degradation caused by the construction sector. To address this issue, the study examines the overall framework of ecological management implemented in Malaysia's construction industry. It evaluates key aspects of construction management, including the formulation and implementation of environmental policies, the involvement of stakeholders in decision-making processes, and the effective management of construction waste. Additionally, the study conducts a comprehensive assessment of specific regulations and guidelines pertaining to construction waste, water contamination, and air pollution, all of which are prevalent issues in Malaysia's construction activities. Furthermore, the study highlights the benefits of using green materials in construction to minimize environmental impact and enhance overall quality of life. It explores the implementation of green technologies in Malaysia, considering their advantages and disadvantages within the local context. By doing so, the study aims to provide insights into the challenges faced in the widespread adoption of green technologies, taking into account the perspectives of the government, economy, society, and available resources. Ultimately, the study emphasizes the need for collaboration among all stakeholders to address environmental damage effectively. It stresses the importance of an inclusive approach, ensuring that no one is left behind in the efforts to rectify the situation and prevent further deterioration of the environment. By taking proactive measures and implementing sustainable building techniques, it is hoped that the construction industry in Malaysia can contribute to a greener and more sustainable future for the nation.

“…The increasing human impacts on freshwater ecosystems have degraded and fragmented aquatic habitats (Baras & Lucas, 2001; Dudgeon et al, 2006; Grill et al, 2019), resulting in a steep decline in fish populations worldwide (Maitland, 1995; WWF, 2022). Still, riverine fish continuously face growing threats from various stressors (Ahmed et al, 2022; Dudgeon et al, 2006; Reid et al, 2019), including climate change, excessive water pollution, and further development of hydropower as part of expanding renewable energies (e.g., EU Renewable Energy Directive 2018/2001; Quaranta et al, 2022). Even though hydropower is widely regarded as being ‘green’, sustainable, and environmentally friendly (Alfredsen et al, 2022; IHA, 2022; Singh & Singal, 2017), this renewable energy source constitutes a key stressor to fish populations (Parasiewicz et al, 1998; Schmutz et al, 2015, 2023; van Treeck et al, 2022).…”

Unnatural changes in river flow patterns resulting from peak‐operating hydropower plants adversely impact freshwater ecosystems. In particular, the rapid dewatering of shoreline habitats during artificial flow down‐ramping puts early fish life stages at a high risk of becoming stranded if they fail to follow receding water levels in time. While extensive research has been conducted on the effects of hydropeaking on salmonid species, there is limited knowledge on the diverse cyprinid family, particularly on vulnerable early life stages. Hence, this study aims to compare the larval stranding of two cyprinid species, the common barbel (Barbus barbus L.) and common nase (Chondrostoma nasus L.), in response to bank dewatering. We conducted larvae experiments in near‐natural mesocosms, simulating single flow down‐ramping events with varying down‐ramping rates (0.3–1.8 cm·min−1) during the day and at night to quantify stranding rates, also including water temperature and fish development. Our results reveal distinct diurnal patterns for both species, with higher stranding rates during the night than during the day in all experimental scenarios. The data also show higher stranding rates at faster down‐ramping, with interaction effects between down‐ramping rates and time of day. The stranding rates between the two species are similar across most of the scenarios. Scenarios with colder water temperatures show that nase larvae tend to strand more frequently than with warmer temperatures. In conclusion, the study results contribute to the ongoing discourse on hydropeaking mitigation by providing new perspectives on flow‐reduction effects on early cyprinid life stages. Mitigation measures should prioritize the periods during early larval development and factor in prevailing water temperatures. Lowering down‐ramping rates, especially during nighttime, will help minimizing negative impacts on aquatic ecosystems, particularly when combining flow rules and habitat restoration measures.

“…1). Hydropeaking is widely discussed in the context of climate change and the rise of renewables to integrate energy production and demand in the power grid [5,6], and to increase flexibility in the energy system [7,8]. However, the ecological impacts of hydropeaking, including reduction of species abundance [9] and biomass [10,11], lowered primary production [12], and altered assemblages of river fauna and flora [13][14][15], are of great concern [16][17][18].…”
