Natural System
• Natural system, which is containing
biosystem, is the source of BIODIVERSITY.
• Biosystem and biodiversity are sources for bio-resources.
Biosystem/Biodiversity Bio-Resources
Biodiversity
“Variety of different species, genetic variability among individuals within each species, variety of ecosystems and functions such as energy and
matter cycling needed for the survival of species and biological communities.”
1. Genetic Diversity
• They are all
cabbages (Brassica oleracea) but they're not the same
because their genes are different.
2. Species Diversity
• For example, both are junglefowls (Gallus), yet they belong to the different species.
Ecosystem Diversity
• Prairies, ponds, coral reefs and tropical rain forests are all
ecosystems. Each one is different, with its own set of
species living in it.

Biosystem/Biodiversity Bio-Resources
Resources Natural Capital
“Anything obtained from the environment to meet human needs and wants.”
Biosystem
The ultimate source for renewable natural
resources.
There will not be sufficient fresh air, fresh water, fertile soil
and biodiversity if the function of Biosystem is degraded.

Preservation & Conservation of Bio-Resources
• Preservation means we do not use the
resources
• Conservation means we use the resources in a careful and thoughtful way
– Management and
sustainable use of the natural environment and natural resources for
ethical reasons and the benefit of humanity

Traditional Knowledge on Bio-Resources:
Energy
• In 1999 some 1.75 billion m3 of wood was extracted for fuel wood and conversion to charcoal ± 90% of which has been produced &
consumed in developing countries.
• 11% of the world energy consumption mainly from fuel wood.
• 19% of China's primary energy consumption comes from biomass, the figure for India being 42% & ± 35% for developing countries

Timber still the commercially most important economic product for most forests. The value of world trade in
industrial wood products is around $140 billion
annually.
