Learning from Samtengang Lake
September 25, 2025:One of the highlights of my academic work this semester was taking a group of both national and international students to Samtengang Lake in Nyisho Gewog, Wangdue Phodrang, for a field training on watershed classification and lake revival assessment. Samtengang Lake, once a thriving freshwater body, is now showing signs of ecological stress and drying, making it an ideal site to bridge classroom theory with real-world conservation challenges.
During the field visit, I guided the students through Bhutan’s watershed classification guidelines, allowing them to assess the condition of the watershed and the lake itself. The day’s activities included visual assessments of watershed indicators such as erosion, vegetation, and land use, alongside water quality testing for parameters like pH, turbidity, and salinity. Students also observed pollution sources and mapped the hydrological connections between the watershed and the lake system. These exercises gave them a first-hand understanding of how ecological health is measured, documented, and interpreted in Bhutan’s context.
For me, Samtengang Lake was not just a field site; it was a living classroom where future ecologists and environmental managers could practice critical thinking, teamwork, and problem-solving. Watching them piece together observations, data, and recommendations gave me confidence that these young minds are ready to take on the responsibility of conserving Bhutan’s watersheds and freshwater systems.
A Special Session with Youths on Freshwater Ecology
September 12, 2025: Last week, I had the incredible opportunity to train 38 student Eco-ambassadors and Focal Teachers from nine schools falling along the Pachhu river, ranging from primary to higher secondary levels. What made this experience even more memorable was the participation of five inspiring students from Wangsel Institute for the Deaf – proving once again that conservation knows no barriers.
These young Eco-ambassadors were given hands-on training on freshwater ecology and conservation, exploring our rivers, spring management, water sources, fish diversity, and the importance of protecting aquatic life. Their energy, curiosity, and enthusiasm deeply inspired me.
The past weeks have been truly special. Within just span of a month, I had the chance to engage with both ends of the spectrum: from young schoolchildren taking their first steps in leadership to Members of Parliaments shaping national policy. It is a humbling reminder that environmental stewardship must begin early, while also being anchored in wise policymaking.
I would like to extend my heartfelt thanks to the Principal of Drukgyel Central School for initiating this remarkable program, and to the focal teachers from all nine schools along the Pachu for their dedication. Gratitude to BES for organizing this jointly. Most importantly, I am grateful to the students, the true change-makers who remind us why we do what we do.
This journey has reaffirmed my belief that by nurturing awareness from classrooms to policy halls, we can create a stronger, more conscious society ready to care for our rivers and ecosystems. I look forward to continuing this journey with schools and communities to strengthen our bond with nature.
Policy Presentation for Cleaner Rivers in Bhutan to the Hon'ble Members of Parliament
August 26, 2025: I had the privilege of presenting our findings on freshwater ecology and aquatic health in the Wangchhu river, as part of the Plastic Free Rivers and Seas for South Asia (PLEASE) initiative. This collaborative effort between theCollege of Natural Resources, Royal University of Bhutan and the Bhutan Ecological Society aimed to assess the impact of pollution—especially plastic waste—on river ecosystems in Thimphu.
It was an honor to share this work with the Hon'ble Members of Parliament National Assembly of Bhutan whose engagement and support are deeply appreciated. We are especially grateful to the Bhutan Ecological Society for funding and facilitating this important project.
Project Summary: Freshwater Ecology and Aquatic Assessments in Thimphu
Scope: 12 streams in Thimphu assessed during pre- and post-monsoon seasons (2024).
Focus: Macroinvertebrate biodiversity, water quality, and microplastic pollution.
Key Findings:
1. Over 9,700 macroinvertebrates sampled; diversity dropped post-monsoon due to flash floods.
2. Pollution-tolerant species like Chironomus and Tubifex dominated in heavily polluted sites.
3. Microplastics (fibers, films, fragments, pellets) were found across all sites.
4. Water quality varied significantly.
Recommendations:
1. Strengthen waste management policies.
2. Engage communities in river clean-up and monitoring.
3. Restore habitats and promote sustainable water practices.
"Be the change—carry your own bag, skip the plastic, and protect our rivers and streams."
Every semester, I have the privilege of teaching Mountain Aquatics to students from the U.S. who visit Bhutan through the School for Field Studies (SFS) program at the College of Natural Resources. My course delves into the freshwater ecosystems of mountain environments, combining theoretical foundations with hands-on fieldwork in nearby rivers. It’s always inspiring to see these curious and talented students quickly grasp complex ecological concepts—often within just a few hours—thanks to their keen interest and strong learning abilities. Over the past six batches, this collaboration has been an enriching exchange of knowledge, and I look forward to seeing it continue for years to come!
Visit to the Central Europe to explore projects and collaboration
Wonderful memories from my recent trip to Slovakia, where I had the privilege of being hosted by Constantine the Philosopher University. I extend my heartfelt gratitude to the university for inviting me to deliver a lecture, engage in meaningful meetings, and explore opportunities for future research collaborations. My time there was filled with enriching experiences and unforgettable moments. I deeply appreciate the efforts of the esteemed professors from the Faculty of Natural Sciences and Informatics (Dean, Head of Department Prof. Henrich, Prof. Veronika, Prof. Hresko, Prof. Grabiel, Prof. Peter, Prof. Vera and Prof. Lucia) who graciously guided me through their impressive research facilities, shared their innovative work, and introduced me to the cultural heritage and rich traditions of Slovakia. So many castles in just one country! Every moment was truly well spent, and I am grateful for the warm hospitality and knowledge exchange that made this trip so special. Looking forward to nurturing these connections and exploring exciting possibilities ahead!
Freshwater Wonders of Slovakia
During my enriching visit to Slovakia, I was fascinated by the country’s abundant freshwater resources—from pristine mountain streams to vast river systems. Witnessing the melting snow trickling down from the Tatra Mountains, feeding into Slovakia’s freshwater networks, was a reminder of nature’s seamless hydrological cycle.
Slovakia is home to over 180 natural lakes, 13,000 km of rivers, and numerous reservoirs, making it a freshwater-rich nation. I had the opportunity to learn about the Váh River, the longest in the country (403 km), which plays a crucial role in hydroelectric power and water management. Exploring Blanka Stanovica, a heritage site, further deepened my understanding of how water has shaped the country’s landscapes, settlements, and cultural traditions.
I also gained insights into Slovakia’s glacial lakes and karst springs, which serve as critical freshwater reservoirs supporting biodiversity. The integration of sustainable water management practices, hydropower development, and conservation efforts in Slovakia offers valuable lessons for freshwater governance worldwide.
A truly inspiring trip, blending science, culture, and the marvels of freshwater ecosystems!
