Global Population Growth and Urbanization 9. This global milestone will have a pronounced urban penchant. These sprawling metropolitan areas will be features in the emerging economies of Asia, Latin America and Africa, with China, India and Nigeria projected to have the highest rates of growth.
It will also be a significant factor in magnifying the impacts of global warming, according to the Sierra Club of the United Nations Population Fund. Right now, global growth is using about 1. This projection underscores the necessity for new approaches and innovative technologies that dramatically reduce or even reverse the effects of CO2 emissions to mitigate the upward trajectory of population growth.
New Technology Delivers Sustainable Building Materials The urbanization of the planet over the coming decades will exert intense pressure on the agility and responsiveness of industry to innovate. The building materials and construction industries must adapt new practices to meet the increased demand for materials to build the housing and transportation infrastructure needed to support the anticipated increase in city dwellers, while reducing CO2 emissions in a resource-constrained environment.
Concrete, the supply chain sibling of cement, is the second most utilized resource after water. Over ten billion tons of concrete are being produced each year.
With increased urbanization, this annual rate is projected to grow to up to 29 billion tons. With Solidia Technologies, the building materials and construction industries have the opportunity to benefit from new, sustainable and profitable technology.Global urbanization map showing the percentage of urbanization per country in Guangzhou, a city of million people, is one of the 8 adjacent metropolises located in the largest single agglomeration on earth, ringing the Pearl River Delta of China.
Mumbai is the most populous city in India, and the eighth most populous city in the world, with a total metropolitan area population of. By , the world’s urban population is predicted to exceed 6 billion.
2 An estimated 70% of the global population will live in cities, demanding 80% of total energy by 3 Rapid population growth and urbanization will have a dramatic effect on the increased demand for jobs, housing, energy, clean water, food, transportation.
This rapid urbanization coupled with population growth is changing the landscape of human settlement, posing significant risks on living conditions, the environment, and development.
Water and sanitation: The total of number of people living in cities without safe water and adequate sanitation has continually increased because infrastructure.
Today, 55% of the world's population lives in urban areas, a proportion that is expected to increase to 68% by Projections show that urbanization, the gradual shift in residence of the human. Human population entered the 20th century with billion people and left the century with billion.
The growth of the last years appears explosive on the historical timeline. The overall effects of this growth on living standards, resource use, and the environment will continue to . Projections show that urbanization, the gradual shift in residence of the human population from rural to urban areas, combined with the overall .
