Sustaining Terrestrial Biodiversity: The Ecosystem Approach

4 important questions on Sustaining Terrestrial Biodiversity: The Ecosystem Approach

At what rate is deforestation currently happening?

0,3 - 0,8 % per year

if the current rate continues: 40% of world's remaining forests will be gone in two decades.

What are the major primary reasons for deforestation in South America, Southeast Asia and Africa?

South America:  cattle grazing, soy bean production and hardwood lumber
Southeast Asia: palm oil
Africa: small-scale farming and wood for fuel.

What is reconciliation ecology?

establishing viable habitats in places where humans already live.

Intervening, establishing and maintaining new habitats to conserve species diversity in places where people live, work or play. We need to learn how to share with other species some of the spaces we dominate.  

this will involve community-based conservation.

What are the four approaches when scientists try to recover ecosystems?

  1. restoration: returning a degraded habitat to a condition similar as possible to its natural state.
  2. Rehabilitation: turning a degraded ecosystem into a functional ecosystem without trying to restore it to its original condition (vb; mining sites kun je niet in compleet dezelfde staat herstellen)
  3. replacement: replacing old ecosystem with a new type: e.g. a degraded forest can become a tree plantation.
  4. artificial ecosystems: creating artificial wetlands to treat sewage.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
