Mayor of Surabaya, Tri Rismaharini hoped that this congress can cope with the city problems. Around 800 participants attend the Congress from 50 cities in various countries in Asia Pacific and several UCLG member countries outside Asia Pacific.When speaking at the UCLG Asia Pacific congress on Wednesday (12/9), Mayor Tri Rismaharini stated that the temperature of the city dropped to 2 degrees Celsius from the range of 34 to 36 degrees Celsius.

She also said that every year, the Surabaya City Government builds 10 to 20 parks, two urban forests, and 10 to 15 sports fields. Her side is also working on the construction of the first Mangrove Botanical Gardens in Indonesia. Surabaya also continues to revitalize the river. So, this makes the temperature drop.
