1 The Effects of Urbanization on Developing Countries Elyse Boelens Leonardo Caion-Demaestri Katherine Carlton How does urbanization affect pollution, deforestation and biodiversity loss on natural ecosystems in developing countries – such as Brazil and China?

2 Methods Looked at the effects of urbanization on different stages of developing countries (Brazil and China). Looked at the effects of urbanization on different stages of developing countries (Brazil and China). Arc GIS maps, Scientific Journals, Group discussions, and Personal Experience were used to display the impacts of urbanization on: Arc GIS maps, Scientific Journals, Group discussions, and Personal Experience were used to display the impacts of urbanization on: –Pollution –Deforestation –Biodiversity Loss

10 Current Problems : Pollution

11 China Pollution Issues Heavy reliance on coal Heavy reliance on coal –74% of China’s energy consumption Sulfur dioxide pollution Sulfur dioxide pollution –2/3 of all Asia’s emmissions –Acid Rain in 40% of country More nitrogen dioxide More nitrogen dioxide –Increase in amount of cars Polluted drinking water Polluted drinking water –Human and animal waste

12 Brazil Pollution Issues Loss of Rainforest Loss of Rainforest –Releases sequestered carbon dioxide Transportation Pollution Transportation Pollution –Sao Paulo increase Petroleum Consumption Petroleum Consumption –51% of energy consumption Hydroelectricity Hydroelectricity –Flooded ecosystems –Displaced Indigenous people 1.htm

13 China vs. Brazil : Pollution Industry Industry –Reliance on coal Transportation Transportation –Increase in cars, nitrogen dioxide Acid Rain Acid Rain –Sulfur Dioxide Water Pollution Water Pollution –Unfit for drinking Transportation Transportation –Dramatic Increase in cars, nitrogen dioxide Deforestation Deforestation Petroleum Consumption Petroleum Consumption Hydroelectricity Hydroelectricity –Flooding –Displacement

18 Current Problems : Biodiversity Loss

19 China Biodiversity Loss Issues Habitat Loss affects 86% of threatened mammals and 86% of threatened birds. Habitat Loss affects 86% of threatened mammals and 86% of threatened birds. Panda’s only source of food – bamboo - is only growing within 500 and 3100 meters. Panda’s only source of food – bamboo - is only growing within 500 and 3100 meters. Area of great biodiversity are the areas where people are taking over. Area of great biodiversity are the areas where people are taking over. Has over 10% of world’s plant and terrestrial vertebrate species, but 1 / 5 are now endangered. Has over 10% of world’s plant and terrestrial vertebrate species, but 1 / 5 are now endangered.

20 Brazil Biodiversity Loss Issues Study shows that only 18% of vegetation survive when 12 km away from a road or city and only 5.9% survive when within 1 km of road or city.

21 China vs. Brazil : Biodiversity Loss Half of China is uninhabited so the population lives within 7% of world’s arable land. Half of China is uninhabited so the population lives within 7% of world’s arable land. Loss of habitat is greatly affected by: Loss of habitat is greatly affected by: –Timber –Agriculture –Fuel wood –Infrastructure –Hydropower development Brazil is home to precious Amazon basin. Brazil is home to precious Amazon basin. –Invasive alien species take over In central Brazil there is a dry forest home to many bird species. In central Brazil there is a dry forest home to many bird species. –Taken over for coal production

22 Societal Implications : Pollution

23 Societal Implications of China’s Pollution 40% of China grapples with issues of acid rain. 40% of China grapples with issues of acid rain. 700 million Chinese drink contaminated water. 700 million Chinese drink contaminated water.

24 Societal Implications of Brazil’s Pollution Growth in the amount of nitrogen dioxide Growth in the amount of nitrogen dioxide –World Health Organization believes it to be the cause of the 30% increase in the amount of deaths from respiratory illness in children under the age of five Increase in amount of hydroelectric plants Increase in amount of hydroelectric plants –1980’s: Created the Brazilian Movement of Dam Affected People to demand fair compensation and active involvement in the decision making process

25 Societal Implications : Deforestation

26 Societal Implications of China’s Deforestation Tree clearing as an outgrowth of poverty. Farmers gradually intruded nearby forests to gather fuel wood and “shake off poverty.” Tree clearing as an outgrowth of poverty.

40 Conclusion Our ArcGIS graphs, along with scientific data show that there is an increase in the negative environmental impacts (pollution, deforestation rates, and biodiversity losses) related to urbanization growth. Our ArcGIS graphs, along with scientific data show that there is an increase in the negative environmental impacts (pollution, deforestation rates, and biodiversity losses) related to urbanization growth. Although the reasons for such growth differed, the results were similar. Although the reasons for such growth differed, the results were similar. If current conditions continue, these countries’ hopes of becoming developed will not be obtainable due to their repercussions on their natural ecosystems.

41 Take Home Message There needs to be a clear shift in today’s mindset and economy towards a focus on the long-term effects each decision has on the environment we belong. There needs to be a clear shift in today’s mindset and economy towards a focus on the long-term effects each decision has on the environment we belong. Create realistic goals that society can put forth and start being the change we want to see in the world.
