Dilmah, in collaboration with the University of Peradeniya, has been partnering for several years with the South Asian Nitrogen Hub (SANH) on a groundbreaking study examining the impact of ammonia on tropical forest ecosystems. This research sheds light on how nitrogen pollution affects biodiversity and ecosystem health, making it a breakthrough regional study in Sri Lanka and South Asia. Filling a major gap in scientific knowledge and data availability, this project has provided the first ever research-quality ammonia monitoring and meteorological data from our region.
More details about the progress of this study can be gleaned from the research team who will present insights and key findings on October 3rd, 2024, from 2.30pm to 5.00 pm at the upcoming event “Lichens: Natural Air Quality Sensors,” at the Genesis: Dilmah Centre for A Sustainable Future in Maligawatte.
Lichens, known for their sensitivity to air pollutants, have been used in the project as bioindicators (species with the ability to measure the quality of the environment) to track nitrogen levels. The event aims to showcase how these organisms help us understand the broader implications of nitrogen pollution on tropical forests and its potential long-term impact on environmental sustainability.
Renowned Sri Lankan lichenologist, Dr. Gothami Weerakoon, curator at the Natural History Museum in London, will present her findings on the use of lichens as bioindicators. Dilmah has previously worked with her on a Dilmah publication “Fascinating Lichens of Sri Lanka”. This event will also feature insights from the larger regional study led by Prof. Mark Sutton, and from the Sri Lanka-focused research headed by Prof. S.P. Nissanka of the University of Peradeniya. The audience will further hear from Dr Ajinkya Deshpande environmental ecologist from UKCEH with a background in climate change effects, forest ecology, pollution effects and air quality monitoring who will attempt to bring to life the project’s impact in numbers.
