6.2 Tropical Deforestation

Engage: what is deforestation?

Step 1: Go to the ArcGIS Online map, Tropical Deforestation, and explore the map.

  • What are the squares and patches within Brazil?

Step 2: Click the left yellow marker to display a pop-up window. Click the image in the window.

  • Describe the image that you see and what the colors represent.
  • What is the relationship between the original green image and the red image?

Explore: how has tropical forest cover changed over time?

Step 3: With the Details pane visible, click the button, Contents.

Step 4: Click the checkbox to the left of the layer name, Forest Loss (by year).

  • What generalizations can be made about the forest loss by year from 2001-2014?

Explain: what are some causes and effects of deforestation?

  • What are some possible causes of deforestation?
  • What are some possible effects of deforestation?
  • Using the evidence provided from the map layer, what is a possible outcome – positive or negative – of increased deforestation?

Elaborate: where is deforestation most severe today?

Step 5: Click the check-boxes (on and off) to the left of the three layers named, Rondonia Fragmentation, Brazil Satellite Image 2000, 2004, or 2008.

​Step 6: Record notes of the patterns that you observe from the satellite images over time.

  • What are some possible causes of these patterns?
  • What are some possible methods of deforestation? What evidence can you gather from the satellite images?
  • How much land has been consumed by deforestation? Using the 2008 Rondonia image, measure a rough estimate of the deforested area. ​

Evaluate: Why should we care about the loss of tropical forests?

  • What are some ecological advantages provided by established, mature tropical forests?

Step 7: Click the check-box to the left of the layer name, Biomes.

Step 8: Click the check-box to the left of the layer name, Biodiversity Hotspots.

  • Describe the locations that you feel demonstrate the most significant number of species over a given region.
  • What are some possible benefits of biodiversity?
