SUB-TOPIC:  BUSH BURNING AND DEFORESTATION

Sub-Topic 1: PRACTICES THAT INFLUENCE BUSH BURNING

Bush burning is the clearing of vegetation by setting it on fire. The reason for bush burning may be for social, economic or agricultural purpose. Practices that can influence bush burning include:

Forest Fire

In this picture a fire rages through Yellowstone National Park in the United States. There are three kinds of forest fires: one that burns a layer of the forest floor only, one that burns surface litter and forest undergrowth, and one that advances through the tops of trees. All three fires can occur at the same time

  1. Building and construction of houses, schools, hospitals, market places, roads, e.t.c.
  2. Some culture see bush burning as a way of celebrating festivals
  3. Hunting of animals in the bush for commercial purposes
  4. The need to remove excessive vegetative cover on farmland before tillage
  5. Some farmers set bush on fire because they see it as a way of disinfecting and destroying pests, disease-causing organisms and weed seeds
  6. The act of setting bush on fire is to encourage fresh growth of green grass for livestock

Practice House Fire

Fire requires heat, oxygen, and fuel to ignite and spread. Here, firefighters practice extinguishing a house fire. While fire is an essential part of our lives—providing heat for warmth, cooking, and certain industrial processes—uncontrolled fire can be a destructive force. In the United States, a structure fire occurs every 55 seconds.
