To what extent can rooftop gardens and flower meadows in cities increase the biodiversity of natural ecosystems in cities?

Given the ongoing climate change, including global warming, air pollution, limited areas of urban parks and other green spaces, gardens, flower meadows established on the roofs of buildings in cities can significantly increase the areas of urban green space. When urban green areas are significantly expanded, the biodiversity of natural ecosystems in cities can also increase significantly. In addition, additional green areas can have a positive impact on the air quality of cities. Air quality is not only a question of pollution levels, but also humidity levels and summer temperatures. Additional green spaces can play an important role in the rest and recuperation of residents, which can translate into improved health for people living in the city. Additional green areas, including gardens and flower meadows, also mean more foraging areas for insects, including pollinating insects, whose numbers are rapidly declining due to the over-chemicalisation of agriculture. Besides, additional green areas in cities can increase the level of sustainability in terms of sustainable development, green building and environmentally and climatically sustainable urban agglomerations.

In view of the above, I would like to address the following question to the esteemed community of scientists and researchers:

To what extent can gardens and flower meadows established on the roofs of buildings in cities increase the biodiversity of natural ecosystems in cities?

What is your opinion on this topic?
