South Africa is considered among the top five most mega-diverse countries in the world, boasting almost 10% of the world’s known bird, fish and plant species and over 6% of the world’s mammal and reptile species contained on a land surface of only 1,1 million square kilometres (1% of the Earth’s total land area).
To highlight the crucial role nature’s rich diversity plays in our lives, the United Nations (UN) has declared 2010 the International Year of Biodiversity (IYB-2010).
Tswaing Crater,about 40 km north of Pretoria, is extraordinarily rich in fauna and flora.
According to the UN Secretariat of the Convention on Biological Diversity, biodiversity (the variety of life on Earth), is essential to sustaining the living networks and systems that provide us with health, wealth, food, fuel and the vital services our lives depend upon.
The Convention, of which South Africa is a signatory, covers all ecosystems, species and genetic resources, linking traditional conservation efforts to economic goal of using biological resources sustainably, setting principles for the fair and equitable sharing of the benefits from use of genetic resources, notably for commercial use and covering rapidly expanding field of biotechnology, and addressing technology development and transfer, benefit- sharing and biosafety.
Unfortunately, South Africa’s increased population growth, habitat destruction, overexploitation, pollution and the introduction of invasive alien species are all placing increasing pressure on our natural systems.
This holds particularly true for South Africa’s freshwater ecosystems, with the 2006 South Africa Environment Outlook indicating that 82% of the country’s main river ecosystems are threatened. Continue reading 2010 – The International Year of Biodiversity
