  1. Deforestation Presented By Team Genius Ariana Woodson, Heng Zhang, Martina Gualtieri, Sandra Flores, Sergio Alvarez, and Alex Bricout

  2. What Is It? • Deforestation is the clearance of naturally occurring forests by logging & burning. • occurs for many reasons: • fuel or as a commodity, • while cleared land is used as pasture for livestock, • plantations of commodities, and settlements. • In many countries, deforestation is an ongoing issue that is causing extinction, changes to climatic conditions, desertification, and displacement of indigenous people. • Among countries with a per capita GDP of at least US$4,600, net deforestation rates have ceased to increase.

  3. Why This Problem? • Natural resources are under increasing pressure, as Terracivians try to balance economic production, resource conservation, and sustainable development • The dense forests of Terracivis have made it a significant exporter of timber • provide habitat for 1,600 species of birds, including 120 endemic species, a number of which are critically endangered • Industries: logging, mining and refining minerals, coal extraction, textiles, fishing, ecotourism

  4. IMPORTANCE OF FORESTS • Multiple benefits to environment, people and animals. -Cool air temperature. -Generation of oxygen. -Sound barrier and reduce light reflection. -Supply higher quality water with less impurity.

  5. Control water level in floods. -Minimization of noise pollution. -Advances in medicine thanks to different herbs and plants. -Place for education and research.

  6. Causes of Deforestation • corruption of government institutions • the inequitable distribution of wealth and power • population growth and overpopulation • urbanization • Globalization is often viewed as another root cause of deforestation • cases in which the impacts of globalization have promoted localized forest recovery. • In 2000 the United Nations Food and Agriculture Organization (FAO) found that "the role of population dynamics in a local setting may vary from decisive to negligible," and that deforestation can result from "a combination of population pressure and stagnating economic, social and technological conditions."

  7. Eviromental Problems • Atmospheric • Deforestation is ongoing and is shaping climate and geography. • Deforestation is a contributor to global warming, and is often cited as one of the major causes of the enhanced greenhouse effect. Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change deforestation, mainly in tropical areas, could account for up to one-third of total anthropogenic carbon dioxide emissions. • Hydrological • Trees extract groundwater through their roots & release into atmosphere • When part of forest is removed trees don’t evaporate away this water and climate becomes dry • Deforestation reduces content of water in soil & groundwater as well as atmospheric moisture

  8. Cont. • Deforestation reduces soil cohesion • erosion, flooding & landslides ensue • Forests enhance the recharge of aquifers in some locales, • forests are a major source of aquifer depletion on most locales. • Soil • Undisturbed forests have very low rate of soil loss, • Approx. 2 metric tons per square kilometer (6 short tons per square mile). • generally increases rates of soil erosion • increasing amount of runoff & reducing protection of soil from tree litter • This can be an advantage in excessively leached tropical rain forest soils • Forestry operations themselves also increase erosion through the development of roads and use of mechanized equipment

  9. Economic Impact • Damage to forests & other aspects of nature could halve living standards for world's poor & reduce global GDP by about 7% by 2050, • a major report concluded at the Convention on Biological Diversity (CBD) meeting in Bonn. • Historically utilization of forest products played key role in human societies • Today, developed countries continue to utilize timber for building houses, and wood pulp for paper

  10. COUNTRIES WITH DEFORESTATION • NIGERIA. -Worst deforestation rate. -CONSEQUENCES: loss of natural systems, extinction of animal species, soil loss and decrease in the number of trees.

  11. BRAZIL. -deforestation caused by constant logging (legal or illegal), cattle ranching, etc. -decrease in the availability of renewable resources (fruits, vegetables…) -destruction of local cultures

  12. CONGO. -causes are building infrastructure, local subsistence activities (mainly agriculture), in addition to commercial logging and mining. -loss of ecosystems, decrease in biodiversity, soil loss and erosion, resources loss…

  13. Congo Brazil Nigeria

  14. Causes of deforestation in the Brazilian Amazon, 2000-2005

  15. Tropical deforestation rates from 2000-2005

  16. Solutions Protect through organizations Greenpeace Convention on International Trade in Endangered Species (CITES) Sustainable logging Balance demands and preservation Plant 10 for every 1 Reduce emissions

  17. Solutions Cont. Controlled farming Manage compaction through confining to narrow strips Reforestation Restock existing forest areas Peace Corps can get volunteers to replant Companies involved in reforestation
