The Faculty of Architecture at the University of Hong Kong recently published the world's first study on the greenspace exposure levels, revealing disparities in greenspace coverage and exposure levels across over a thousand cities worldwide. The study scientifically measures the opportunities for residents in different regions to interact with greenspaces. Despite Hong Kong and Singapore having greenspace coverage rates of 70% and 84% respectively, the exposure levels are only 35% and 55%. According to data from the Planning Department, around 65% of Hong Kong's land is covered by forests, shrubs, and grasslands, including parts of country parks or nature reserves. The government has been promoting urban greening for many years to develop a greener environment in Hong Kong. In 2010, the Greening, Landscape, and Tree Management Section was established under the Works Branch of Development Bureau to coordinate various departments in establishing multi-level greening, landscaping, and tree management strategies. How effective have these efforts been?
