Small Hydropower and Sustainable Development: Current Research and Future Directions

What is it about?

The research conducted a comprehensive bibliometric analysis of small hydropower (SHP) research, reviewing 1108 articles published from 1990 to 2022. The research aimed to provide an overview of global SHP research trends and their connection to the United Nations Sustainable Development Goals (SDGs). By employing scientific mapping and text mining techniques, the study analyzed changes in research topics over time, particularly before and after the SDGs were introduced in 2016. The research identified popular keywords, co-occurrences, and connections within SHP research, uncovering emerging directions and trends. It found that SHP is linked to several SDGs but also noted potential conflicts with SDG 14 concerning water ecosystems. The research concluded with recommendations for improving SHP management to support sustainable development in ecological, economic, and societal contexts.

Why is it important?

This study is important as it highlights the underappreciated role of small hydropower (SHP) within the framework of sustainable development, particularly in relation to the United Nations Sustainable Development Goals (SDGs). By conducting a comprehensive bibliometric analysis of SHP research from 1990 to 2022, the study provides a clearer understanding of the current state and trends in SHP research, emphasizing its potential to support multiple SDGs. This research is crucial for guiding future scholars and policymakers in integrating SHP more effectively into sustainable energy strategies, thereby contributing to global efforts in renewable energy development and environmental conservation. Key Takeaways: 1. SHP and SDGs Connection: The study identifies and explores the complex linkages between SHP and the SDGs, demonstrating that while SHP is not explicitly mentioned, it plays a critical role in achieving renewable energy and greenhouse gas emission reduction targets. 2. Research Trends and Analysis: Through a temporal analysis of 1108 articles, the study reveals evolving research trends in SHP before and after the introduction of the SDGs, highlighting emerging directions and the interdisciplinary nature of SHP research. 3. Environmental Management Challenges: The study underscores the potential conflicts between SHP development and SDG 14 (Life Below Water), calling for improved management practices to mitigate adverse impacts on water ecosystems and promote sustainable SHP practices.
