Research papers presented at the International
Forestry Environment Symposium held recently organized by
Department of Forestry and Environmental Science, University of
Sri Jayewardenepura, Sri Lanka, highlighted many new channels of
economic development some of which are listed below.
Usually rubber plantations are used for
extraction of latex; but it has high carbon trading potential.
Based on estimated models, high carbon content such as 47MT was
achieved from rubber trees at the age of 23 years, which yields
carbon benefits of 77,000 per hectare. .
Heavea rubber can be used for reducing
greenhouse effect in several ways. Naturally producing latex in
Heavea rubber trees absorb CO2 from the atmosphere. Due to the
increasing number of seedlings to be planted per hectare, all
the rubber growing countries can increase CO2 absorption. This
would help to earn money for rubber growing countries under
Rubber wood is used as firewood and chemically
treated rubber wood can be used in furniture industry, reducing
felling of forest tress. Rubber seed oil, after chemical
modification is a proven replacement for diesel to be used for
motor vehicles, reducing use of fossil fuels.
Japan Jabara a problematic aquatic weed in Sri
Lanka has received scientific attention for Biological Control,
as safe application of Herbicides is not possible. Scientists at
University of Sri Jayewardenepura discovered that dry leaf
powder of Gandapana trees could effectively be used for
controlling the weed.
There is no specific drug or vaccine for the
treatment or prevention from the dengue and chikunguina in the
country. Therefore, controlling the vector is the best strategy
for dengue control. A mosquito species scientifically named as
Toxorhynchites splendens has been identified as a predator
insect that can be used to control dengue and chikunguina
mosquito larvae Aedes albopictus. This predator insect does not
feed on blood and cannot act as vectors of the diseases.
A huge extent of forests in Sri Lanka has been
fragmented and therefore animals have to live in the pereiphery
and not inside the forests. The conditions inside a forest are
different to the conditions on the edges of it. A remarkable
disparity was discovered, in the abundance of the endemic and
non-endemic small mammals between inside forests and forest
