INTRODUCTION

Climate change is one of the primary concerns of humanity

today (Lasco et al. 2002).

The World’s forest is shrinking by 0.38% and converted to

other land uses every year.

In fact, according to FAO (2003), 23,260 km2 of forests are

destroyed per year in Southeast Asia. Problems leading to

poverty rise are even exacerbated by human-aggravated

natural disasters.

Plantations intended, not for timber but, for other purposes

such as fruits and seed sources, and other non-timber

products (one of which is latex production) have valuable role

in relation to climate change.

Similar with the forests, plantations can be sources and sinks

of carbon. Its non-use value, carbon sequestration for

instance, sometimes outweighs natural forests.

Much of the carbon sequestration, according to Lasco and

Pulhin (2003), is attributed to the existence of tree plantations

with a sequestration rate of up to 15 t ha-1 yr-1
