MIT-WPU Study Warns Of Dragonfly Decline In Pune, 27 Species At Risk Amid Urbanization
Pune: A recent study by researchers at MIT World Peace University (MIT-WPU), Pune, has revealed significant changes in dragonfly populations across the city, highlighting the impact of rapid urbanization, water pollution, and climate change. The study, based on historical and contemporary data, found that eight dragonfly species recorded in the past are now absent, suggesting possible local extinctions. However, researchers also documented the addition of 27 new species, likely due to increased awareness and citizen science initiatives.
The study, the first of its kind, examines long-term shifts in dragonfly and damselfly populations in Pune over nearly two centuries. Researchers identified key factors influencing these changes, including land-use modifications and data gaps in historical records. Five endemic species from the Western Ghats were recorded, reinforcing Pune’s ecological importance for Odonata research.
Led by Dr. Pankaj Koparde (Faculty, Department of Environmental Studies, MIT-WPU), along with Arajush Payra (PhD Scholar) and Ameya Deshpande (Alumnus), the study analyzed data collected from 52 locations across Pune district between 2019 and 2022. Historical records dating back to the mid-19th century were reviewed using 25 published articles and citizen science databases. The research has been published in the International Journal of Tropical Insect Science (Springer Nature).
“Dragonflies play a crucial role in urban ecosystems by controlling mosquito and pest populations. Their presence is an important indicator of environmental health,” said Dr. Koparde. The study identified Warje, Vetal Hills, and Pashan Lake as the most species-rich areas within Pune Municipal Corporation (PMC) limits.
Building on these findings, researchers at MIT-WPU are currently investigating the impact of urbanization and water pollution on dragonflies along the Mula River. They are also establishing long-term monitoring projects to track biodiversity changes over time.
“We must prioritize the conservation of urban green spaces, including hills, grasslands, rivers, and lakes. Sustainable development is key to protecting biodiversity amid rapid urban expansion,” said co-researcher Arajush Payra.
This research is part of a larger initiative on dragonfly diversity across the Western Ghats, funded by the Department of Science & Technology (DST), Government of India. The researchers hope their findings will encourage further studies on biodiversity shifts and support conservation efforts in urban ecosystems.
