1The Effects of Urbanization on Developing Countries How does urbanization affect pollution, deforestation and biodiversity loss on natural ecosystems in developing countries – such as Brazil and China?Elyse BoelensLeonardo Caion-DemaestriKatherine Carlton
2MethodsLooked 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:PollutionDeforestationBiodiversity Loss
3What are we modeling? Cumulative Carbon Dioxide emissions. Cumulative Sulfur Dioxide emissions.Protected Land.Percent of Deforestation and Total Forest Area.Number of Threatened Species – Birds and Mammals.Gross Domestic Income and Percentage Use by Sector.Gross Domestic Income per Capita.Urban Population and its Percentage Growth by 2030.
11China Pollution Issues Heavy reliance on coal74% of China’s energy consumptionSulfur dioxide pollution2/3 of all Asia’s emmissionsAcid Rain in 40% of countryMore nitrogen dioxideIncrease in amount of carsPolluted drinking waterHuman and animal waste

15China Deforestation Issues One of the most environmentally unsound nations in the world.Major deforestation due to production of commercial lumber.Slash-and-burn agriculture.Lack of government action.
16Brazil Deforestation Issues Nearly 750,000 km2 of forest have been destroyed.1/3 of deforestation can be linked to “shifted” cultivators.Deforestation attributed to land clearing for commercial and speculative interests.
17China vs. Brazil : Deforestation 125,000ha cut down for railroads, highways, and high voltage lines.47,000ha burned down in forest fires.Lack of effective family planning program.Large cleared areas used for cattle feeding.Deforestation for investment purposes.Use of tax incentives that favor pastureland over natural forest.
19China Biodiversity Loss Issues 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.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.
20Brazil 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.Alien species are greatly affecting the native species.
21China vs. Brazil : Biodiversity Loss Half of China is uninhabited so the population lives within 7% of world’s arable land.Loss of habitat is greatly affected by:TimberAgricultureFuel woodInfrastructureHydropower developmentBrazil is home to precious Amazon basin.Invasive alien species take overIn central Brazil there is a dry forest home to many bird species.Taken over for coal production
23Societal Implications of China’s Pollution 40% of China grapples with issues of acid rain.700 million Chinese drink contaminated water.
24Societal Implications of Brazil’s Pollution Growth in the amount of nitrogen dioxideWorld 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 fiveIncrease in amount of hydroelectric plants1980’s: Created the Brazilian Movement of Dam Affected People to demand fair compensation and active involvement in the decision making process
26Societal 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.”Focus on profit-making while overstepping villager’s rights and interests.Bare hillsides will worsen natural disasters and engender a new form of poverty.
27Societal Implications of Brazil’s Deforestation Risk of quality of life.Gamble with stability of climate and local weather (Lack of humidity and rainfall).Threaten the existence of species.Undermine valuable services provided by biological diversity.Increase erosion, floods, drought, water pollution.Lack of fisheries protection and pollination.
29Societal Implications of China’s Biodiversity Loss Cities within China will grow to completely take over the biodiversity.Complete reliance on international institutions for money to protect biodiversity.Affect region’s lifestyle.The cost of the effects together with the related problems that can arise (like disease, and other illness, or rebuilding and so on) is much more costly than the maintenance and sustainable development practices that could be used instead.
30Societal Implications of Brazil’s Biodiversity Loss With urbanization, small villages around the Amazon basin are going to suffer due to lack of food sources and increase of endangered species.External reliance of different organizations to aid with loss of particular species.Exports of soybeans and coffee will exponentially decrease if trends continue.
32Possible Solution for China’s Pollution Branches in place to monitor pollution.State Environmental Protection CommissionNational People’s CongressEnvironment and Resources Protection CommissionEnvironmental Protection Agency350 Cities conduct routine air quality monitoring.Decline in Sulfur Dioxide.Closure of small, inefficient plantsControlling use of coalNeed to better monitor water quality and create standards.
33Possible Solutions for Brazil’s Pollution Address transportation issues.Mass transportationAlternative fuels1999, restricted days on which people droveRenewable energy use.31% of energy comes from hydroelectric plants13% from renewable sourcesLargest producer and consumer of ethanol from sugar cane
35Possible Solutions for China’s Deforestation Law enforcement of only selective logging.Increase large-scale protection forests and nature reserves. Particularly of non-active management land (15% of China’s territory).Redirect economy away from virgin forests.Emphasize the development of institutions to significantly reduce property right protection costs for forest management.Increase taxes on timber production.
36Possible Solutions for Brazil’s Deforestation Teach others about the importance of the environment.Restore damaged ecosystems by planting trees on land where forests have been cut down.Encourage people to live in a sustainable manner.Increase national parks to protect rainforests and wildlife.Support companies that operate in ways that minimize damage to the environment.Develop new conservation policy built on sustainable development.
38Possible Solutions for China’s Biodiversity Loss Currently Global Environment Fund and World Bank support creation of 1,551 national reserves.Plans are a start but not enough compared to the high growth rate.Slowing rate of biodiversity loss helps animals adjust and adapt to the earth’s changes because of the urbanization.
39Possible Solutions for Brazil’s Biodiversity Loss Continue with current plans to make new national parks and expand national forests.Regulate size and materials used for infrastructure.Increase awareness of current problems and future consequences it will have on society.
40ConclusionOur 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.If current conditions continue, these countries’ hopes of becoming developed will not be obtainable due to their repercussions on their natural ecosystems.
41Take Home MessageThere 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.
