In the foreseeable future, our cities will grow in number and size, and so will the problem’s they’re faced with. A review recently published in Future Cities and environment describe’s the exciting innovation’s already being introduced in cities (to cope with these problems) as well as those which could become reality in the near future.
The development will not only have positive but also negative effects. Problems that are already visible today – like land and food shortages, heavy traffic loads, urban global warming and air pollution to name a few will worsen in the future.
By 2050, 66% of the world’s population will live in urban areas and our cities will increase both in number and size, according to the U.N. Report.
- Shortage of land by increasing population.
- Shortage of food.
- Global warming
- Buying a house next to impossible.
- People spend more time traveling and by traveling, we mean from home to work and back.
- The country becomes more plastic less natural
- Water scarcity
- Other problems in the context of crimes like robberies, rapes, murder’s will takes place by 2050.
Will Our Cities be Pollution Free?
Let us talk about that but I don’t think so ……
Air pollution is one of the most important factors that can affect the quality of citizens life in the urban environment. Consequently, monitoring air pollution is currently a critical issue that needs to be addressed for enhancing the well being of citizens. Today there is an increasing concern of citizens and city administration on air pollution because of its possible significant impact on human health.
By 2050 pollution of any type (air, water, soil pollution) will increase at a higher level and unable to bear. Today world cities negatively affected by pollution that significantly deteriorates the quality of life of dweller’s. Air quality can vary over time across different areas of the city and it is also influenced by different factor’s such as weather conditions (e.g. humidity, temperature and atmospheric pressure, human activities (e.g. traffic flows, people’s mobility) provided services and the presence of points of interest in urban areas.
With the evolution of mobile communication protocol and sensing technologies, innovative sensor’s have been developed to monitor a wide range of pollutants, thus evaluating air quality.
The toxins in the air are invisible, they continue to choke us each day. Nearly 95,00 people die each year in London because they are exposed to the toxic gas nitrogen dioxide (NO2).
According to a study by King’s College London, the situation around the world from New York to Delhi to Beijing is no better.
The key problem is the commercial and residential building sector’s output, which accounts for 39% of annual CO2 emissions in the U.S. According to a report transport sector generates 33% of CO2 emission.
Some of the polluted cities of the world are as follows.
What will they become in 2050 if they are not taken into consideration? Out of the 10 largest polluted cities, 9 are in India.

Pollution Prevention for Future
Environment sustainability implies meeting our current needs without jeopardizing the right and ability of future generation to meet their’s
- To reduce the production of waste’s and use of toxic materials, to prevent soil water and air pollution.
- To conserve and reuse resources as feasible.
With increasing population pollution has become a great concern. With the comprehensive pollution programmes for its prevention, most of the pollution can be reduced.
Best way to deal with pollution is to prevent it from being created in the first place. Understanding how waste is produced and how it can be minimized.
Fundamental ideas of prevention rather than fixing problems are essential for efficient viable manufacturing, providing services and addressing many environmental problems.
Our responsibility is to utilize our knowledge to take actions that are protective of human health and the environment.
Reducing short-lived climate pollutants for climate change mitigation.
