Continuously Increasing Urbanization is Dangerous

By 2030, The Area Of Three Million Sq Km May Convert In Cities


In a study assessing the impact on biodiversity due to increasing urbanization, almost three million square kilometers of natural areas will be devastated and transformed into cities by 2030. Its size will be larger than the whole of Britain. Researchers surveyed over 900 studies and claimed this. The study, published in the journal Nature Sustainability, states that by 2030, 120 million people worldwide will be able to move to urban areas. Researchers at Canada’s MC Gill University said,’ This pace of development could create a new city of the size of New York every six weeks.’

Andrew Gonzalez, the co-author of this study and researcher at McGill University, said: “It is important to understand the impact of an increasing urban population on future biodiversity goals, but we need to improve understanding and knowledge.”

Most affected in coastal areas

If we are unable to do so, it may also affect our ability to formulate new and effective urbanization policies. The study suggested that the direct impact of increasing urbanization on biodiversity would be more serious in tropical coastal areas such as China, Brazil and Nigeria, as the level of biodiversity is quite high. In this study, the authors state that scientists are not studying the effects of urban development in the right places. As a result, the picture of increasing urbanization is not clear. He said we need more studies to get a complete and clear picture of the impact of urbanization on our nature. Researchers have argued that the expansion of cities in low-income countries in the Southern Hemisphere has caused the most damage to natural habitats, which is serious and worrying. He said that in order to assess its effects more specifically, the areas surrounding tropical rainforests, such as Brazil, West Africa and some areas of South-East Asia, need to be studied.

The study reported that 72% of the research has been done in high-income countries where urbanization has the highest impact on biodiversity. Researchers claim that the situation in low-income countries may be more serious. Researchers said that only 34% of the 922 studies quantified the indirect effects of urban development on biodiversity. He said that if biodiversity is to be maintained, it will also have to rein in increasing urbanization and population.
