The Yokohama Green-Up plan

achievement


◆Green space preservation is proceeding 

     Green space policies are generally carried out with long term perspectives. However, the city’s initial 5-year plan (FY 2009-2013) has already shown various impacts on green space conservation.
     In particular, the amount of forest areas designated annually have increased to five times more than previous figures under a green space preservation system utilizing revenue acquired from the Yokohama Green Tax. Furthermore, the city of Yokohama takes measures for the acquisition of land in the case of property succession or other unforeseen situations where green space retention is not possible. During the initial 4 years (FY 2009-2012), the city has purchased 105.9ha of designated forest areas.
     Arranging these frameworks, the city has successfully put a brake on the speed of green space shrinkage.

◆Green space policy and Climate Change 

     The preservation of green space is a critical factor in both climate change mitigation and adaptation sphere. Greenery is endowed with multiple environmental and social functions, such as flood risk reduction, landscape maintenance, biodiversity conservation and the prevention of the heat island effect.
  The images below show the environmental benefits of green space as a mitigating factor of the heat island effect.
  
The average temperature distribution in summer (July-Aug.) is compatible with the distribution of green space within the city.
