Analysis of deforestation patterns in the central Menabe, Madagascar, between 1973 and 2010
Abstract
The central Menabe
region still holds the largest remnant of dry forest in western
Madagascar. These forests are home to high floral and faunal diversity
including a number of local and regional endemics. The forests of the
central Menabe have been classified as conservation hotspots. However,
pressure on these forests is strong and deforestation continues on a
large scale. To quantify recent forest loss, we used a series of
satellite images (1973–2010) for estimating annual deforestation rates.
The overall rate was 0.67 %, but it accelerated during certain periods
to over 1.5 % with a maximum of 2.55 % per year between 2008 and 2010.
Not all areas within the forest block of the central Menabe are affected
similarly. Areas surrounding existing clearings show the highest losses
of largely undisturbed forest. If deforestation continues at the same
rate as during the last years, 50 % of the 1973 forest cover will be
gone within the next 11–37 years.
