Joel Lönnqvist's main research interest is related to green infrastructure and its role for managing urban storm water. Joel has a background as a biologist specialized in limnology and has earlier been working with the landscape effects on water plant diversity.
An important part of the current work is to evaluate and to optimize the function of green roofs in cold climates. The function in this case is regarding the storm water management, water quality and plant survival. In the future this function can come to be extended into ecosystem responses to urbanization and the recreating of natural habitats and wildlife corridors in urban areas.
More than function, green roofs may as well come to be evaluated regarding long term use, maintenance measures and possible energy savings. With his research Joel wishes to contribute to overcoming the challenges that arise due to rapid urbanization and minimize the loss of ecosystem functions.
