When you come from the suburbs to the big city, you can notice that the temperature in the metropolis is slightly higher than outside it. On average, the difference in temperature is 4 degrees. Scientists confirm this phenomenon, explaining it by the fact that there is an acute shortage of green vegetation in densely populated neighborhoods. In addition, stone buildings and asphalt retain heat. People simply suffer from heat, which becomes unbearable. Is it possible to solve this problem?
Google believes that the problem can be solved. At first glance, it looks simple. It is necessary to green urban areas where there are so few trees. But to do it right, you need to know exactly how many trees and where to plant them. “The Corporation of Kindness knows how to solve this problem. Its solution is presented in a new large-scale project Tree Canopy Lab. In its framework, artificial intelligence will be engaged in the analysis of aerial photographs of cities, identifying places that require landscaping. It is important to note that the maps will be dynamic and updatable.
The first city to be “cooled down” by Google will be Los Angeles. The company already has information that at least half of the city’s residents live in neighborhoods where the area occupied by trees is not more than 10% of their total area. Against the background of a general increase in temperature, “waves” of heat in Los Angeles have become not only more intense but also longer. It is planned to carry out “cooling” works in two approaches, which in total will give the expected temperature reduction.
The first is to shade the hottest areas as much as possible with the planting of trees. The second is to plant those tree species that are able to release a lot of moisture into the air in the heat, which also contributes to the temperature reduction. And more recently, Google has started using a new tool that is suitable for mapping. It is called “wood stability assessment” and describes the ratio of woody vegetation to area and population.
