4th
largest island
population is over
25
million
50
species of lemurs /
15
of which have become
extinct
in 2010, forest covered
22
% of the island
the rainforest
occupies
narrow
belt in the north and then runs down entire
eastern region
lower
forest-lower Monoene slopes of eastern ridge of
highlands
deforestation in the area
heavily forested until
1970
population growth = demand for
food
production and
economic
progress
over
70
% of the population lives in
rural
areas
they rely on
woodland
for fuel, jobs and
food
forest cleared to extend
culturable
land
loss of
3/4
forest due to
deforestation
involves slashing and burning, logging,
wildfires
, land conversion-agriculture and
fuelwood collection
water cycle impacts :
soil erosion
gullies
formed in the
highlands
soil
loss rates is
7x
global average
water cycle impacts : increased run off
sediment
flowed into river
slow
channel
discharge
damages
land for cultivation
water cycle impacts :
soil infiltration
reduced
groundwater availability and
drier
soils
increased
heat
leads to soil sealing impermeable therefore even less
infiltration.
water cycle impacts: less
transpiration
local -
drier
atmosphere
longer than normal dry season (
clouds
less liable to form)
carbon cycle impacts
burning
forest
slashed
leaves
and steams rapidly
decompose
on the surface
carbon removed from
long
term stores
grazing aimals= more
methane
/
20
more
methane
produced than co2

endangers
isolated
and
unique
species
out of 50 species of
lemur
, 15 have become
extinct
in the recent decades
3000 of
madagascars plants
and animals are threatened with
extinction
drier
local atmosphere,
higher temperature
and changes in ocean and wind patterns
REDD PROJECT
reducing emissions from deforestation and forest
degeneration
and conservation and sustaining
development
400,000
hectoares set aside from deforestation and allocateed as
carbon credit schemes
- absorbs 705,558 tonnnes of CO2
guartees
