Transcript of deforestation
****the current deforestation rate is around 2 percent per year Wildlife sanctuaries Industrialization & Conversion
to human settlement Deforestation the term which
of trees in
forested areas WHAT ARE THE CAUSES????? Logging—both legal and illegal Shifting cultivation(kaingin system) Overgrazing *SOIL EROSION
*DISRUPTION OF THE WATER CYCLE
*LOSS OF BIODIVERSITY
*DROUGHT Sample Effect of Deforestation Typhoon Sendong at CAGAYAN DE ORO Nasa Deforestation Image Spanish arrived in the Philippines in the 16th century scattered coastal areas had been
cleared for agriculture and villages LITTLE HISTORY >>>A few hundred years ago, at least 95 percent of the Philippines was covered by rain forest; only a few patches of open woodland and seasonal forest BUT At the end of more than 300 years of Spanish colonial rule, rain forest still covered about 70 percent of the Philippines. Some islands had been heavily deforested, while others remained nearly untouched. Cebu was so badly deforested; Bohol and Panay had less than half of their original forest much of the highland rain forest remained intact having the highest density of both unique and endangered species in the world, its decline in old-growth forest from 70 percent to seven percent in less than a century is probably the most rapid and severe in the world.......:((((

Philippines Forest Figures (2010) Only about 5 percent of the Philippines land area is under some form of protection. Over the past century, the islands that make up the Philippines have lost nearly three-quarters of their mangrove forests.
The current rate of mangrove deforestation ranges from 2,000 to 3,000 hectares per year.
