Lecture 9 - Expansion of Oil Palm Flashcards
What was the increase in oil palm area between 1999-2008?
56% increase in area
What was the Mha expansion of oil palm between 2001-2011?
5.5 Mha expansion
What is the ‘deforestation capital’
SE Asia - Indonesia
What was most oil palm expansion at the expense of?
Most expansion at cost of primary and selectively logged tropical forest.
What’s the future demand for palm oil?
+60m tons
Does oil palm drive loss of C
yes
What does science say about oil palm expansion?
It releases C -_-
What t/ha of C does a dry dipterocarp forest ‘reduce’?
-163 t/ha
What t/ha of C does a peatswamp forest ‘reduce’?
-1450/tha
How long does C reduction take to surpass dry dipterocarp forest C storage?
75-90yrs
How long does C reduction take to surpass peatswmap forest C storage?
600 yrs
How does Palm Oil affect species loss?
It increases it massively
What is functional diversity?
FD quantifies the range and abundance of functional roles played by species within a community.
Functional roles = functional niches
What is functional richness?
The volume of a functional trait space occupied by a set of species.
What does FD/FRic = Ecosystem services mean
It means the provision of a natural resource or process that is valued by humankind
What does oil palm do to functional richness?
SEVERELY REDUCES IT
What did Edwards et al find about Ibis?
Caused loss of bark cleaners and arrival of water-related species.
What did Edwards find out about dung beetles?
An absence of rollers, less diet generalist species while more small species.
