Today some of the problems faced by both China and India are almost same but the approach to solve them are different. Air pollution is one of the greatest problems faced by major cities in both the countries which is the direct result of population explotion, urbanisation and unprecedented growth in industries and vehicular traffic. But unlike India which is running after odd-even numbered cars to tackle the problem, China is planning “ventilation corridors” to prevent the kind of smog seen in downtown areas.

Beijing Meteorological Service has put forward a proposal to build 17 “ventilation corridors” to save itself from pollution problem. These corridors are planned as a network of parks, rivers, highways, bridges and low buildings, which together allow air to travel more freely. One of the objectives of this proposal is to prevent the expansion of Beijing’s heat island which is already 1,175 square kilometers, involving about 80 percent of the six downtown districts. In the heat island the temperature is significantly warmer than surrounding rural areas because of materials like concrete and asphalt, as well as other things related to human activity.

Temperature within heat island is 3 degrees higher on average than in the surrounding countryside. Development of ventilation corridor will help the wind blowing from the north to disperse airborne pollutants in central Tongzhou by improving circulation. The Beijing city government is relocating to new offices in the east-side Tongzhou district as a part of strategy to decongest the crowded areas. It is believed that free movement of air aided by ventilation corridor will help to bring down the temperature and also reduce the problem of smog in the city.
