Other Effects of Deforestation

How Does Deforestation Affect the Economy?

  • Deforestation facilitates the generation of raw material for a wide range of industries. Examples include the agriculture industry, the wood industry, and the construction industry.
  • However, the overexploitation of wood and timber can have a negative impact on the economy. The short-term economic gains made from deforestation are accompanied by reduced long-term productivity.
  • For example, overenthusiastic timber harvesting from a forest area may increase the overall output temporarily, but the declining forest area will eventually cause the harvest to decline. The overall forest output is greatly reduced by such practices.
  • According to some reports, the global GDP may see a 7 % decline by the year 2050 due to deforestation and other factors.
  • Therefore, a sustainable approach to the usage of forest resources is ideal for the economy.

Deforestation and Human Health

  • Deforestation can, directly or indirectly, provide a channel for the propagation of many infectious diseases. Since deforestation is often accompanied by the loss of indigenous species, it is not uncommon for new species to flourish in deforested lands.
  • In Malaysia, the geographic shift of the fruit bat population (as a consequence of deforestation) facilitated the transmission of the Nipah virus. Fruit bats, which are known to be vectors of the disease, lost their natural habitat due to deforestation and started feeding in the orchards surrounding habited areas. Through proximity, the Nipah virus spread from fruit bats to pigs, and then to humans.
  • Increased soil erosion (due to deforestation) can result in the formation of pools of stagnant water. These pools serve as breeding grounds for mosquitoes, which are vectors of several deadly diseases such as malaria and yellow fever. Some theories also suggest that deforestation has contributed to the propagation of the human immunodeficiency virus (HIV) .

How Can Deforestation be Controlled?

Role of Governments and Other Administrative Authorities

The following strategies can be implemented by governments to combat deforestation:

  • Implementation of security measures and strict laws to prevent illegal logging.
  • Increasing the count and range of forests under government protection.
  • Carefully planning the construction of infrastructure (roads, dams, etc.) in order to minimize the loss of forest area.
  • Investing in new technologies in the agricultural industry (such as hydroponics) and helping farmers implement eco-friendly agricultural practices (such as cyclic agriculture) .
  • Optimizing the management of forests by banning inefficient agricultural practices (such as slash-and-burn agriculture) .
  • Facilitating the production and use of wood alternatives to reduce the demand for timber. For example, bamboo can serve as an alternative to wood fuel.
  • Launching new reforestation campaigns to restore deforested lands.
  • Investing in forest plantations – forests planted with high yielding trees can offer 5 – 10 times the output (per hectare) of a natural forest.

Role of Individuals

  • Every human on the planet shares the responsibility of preserving its resources (for other humans, other species, and for future generations) . An individual can contribute to the prevention of deforestation by implementing the 3 R (Reduce, Reuse, and Recycle) principle in their daily lives.
    • Reduce – Reducing the amount of paper consumed by using alternatives wherever possible.
    • Reuse – Avoiding use-and-throw products to prevent wastage.
    • Recycle – Diligently recycling all used wood and paper products.
  • Individuals can also combat deforestation by spreading awareness about its negative consequences and participating in tree-planting campaigns.

Questions

What Are the Key Causes of Deforestation?

Answer:

  • One of the leading causes of deforestation is agriculture and cattle grazing. Forest land is frequently cleared and transformed into agricultural land in order to keep up with the ever-increasing demand for food (which can, in turn, be linked to overpopulation) .
  • The four commodities that are majorly responsible for tropical deforestation include palm oil, timber, soy, and beef. Generation of grazing land for cattle is another leading cause of deforestation.

What is Deforestation and Its Effect?

Answer:

  • Human-driven and natural loss of trees — deforestation — affects wildlife, ecosystems, weather patterns, and even the climate.
  • Climate 101: Deforestation. Forests cover about 30 percent of the planet՚s land mass, but humans are cutting them down, clearing these essential habitats on a massive scale.

What Are the 5 Effects of Deforestation?

Answer:

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
