The first open event of the GRAD project tok place on the 6th and 7th of December 2019 in Cracow, Poland. It was a seminar and workshop held under the theme „Green roofs as a tool for climate adaptation of urban areas”. They were addressed to the representatives of local self-governments from all over Poland interested in the topic of climate adaptation and development of green infrastructure. During the seminar the participants had the opportunity to get more familiar with the German and Polish climate policies, as well as green roofs’ role in cities’ sustainable development. They also learned more about the Hamburg’s Green Roof Strategy, which will be used as a model for 8 Polish pilot strategies. The initial presentations were followed by a series of good practice examples in the area of city greening. The workshop part was more practical and focused on the key elements that an efficient green roof strategy should contain, as well as what aspects should be consider when developing such a strategy.
