Profs. Paul Johnston and Laurence Gill from the Department of Civil, Structural and Environmental Engineering to speak at COP26 event - the UNEP Peatlands Pavilion at COP26

10 November 2021

Profs. Paul Johnston and Laurence Gill from the Department of Civil, Structural and Environmental Engineering are speaking at a COP26 event - the UNEP Peatlands Pavilion at COP26 - Wednesday November 10th. 

They will be talking about the role of ecohydrology in peat forming wetland systems in relation to understanding the unique biodiversity of such ecosystems as well as being able to uptake and store atmospheric carbon.

The event has been convened by a group of peatland researchers and practitioners across Ireland (led by Natural Sciences in TCD) and will present key messages from the Peatlands Gathering 2021, that was held Oct 7-9th. See highlights here

Paul Johnston and Laurence Gill have spent many years researching the ecohydrology of different wetland ecosystems in Ireland such as raised bogs, fens and turloughs, investigating the link between hydrology and biodiversity and also its regulation of different greenhouse gas emissions and uptake to quantify how much carbon sequestration is achieved by these ecosystems under different conditions. Much of Ireland’s raised bogs in the Midlands have been industrially harvested over the last few decades, meaning that there are very few bogs remaining in pristine condition. The government has recently provided significant funding to Bord na Mona to embark on an ambitious plan to rewet these degraded areas in order to regenerate the areas back to heathy raised bog ecosystems again which will start to take up carbon. Knowledge of the ecohydrological dynamics for such wetlands is therefore essential if the planned restoration back to healthy growing bogs is to be successful.
