impacts of deforestation Flashcards
forests contain 80% of all of the land-dwelling species on earth.
the number of species on the planet continue to decline, partially due to deforestation, over the past few hundred years humans have increased the extinction rates by as much a 100 times.
forests filter and regulate run-off, thus improving water quality. fresh water comes from forested watersheds. also protect against floods.
water quality is declining, and flood frequency and magnitude is increasing, as a consequence of forest cover loss.
forests influence climate by providing a source of atmospheric moisture, shade and shelter from wind.
forest modulate land atmosphere fluxes of heat energy and water, so their loss can have a local warming and drying effect.
forest tourism = positive effect on poorest households (eg employment opportunities)
the ecotourism market has grown three times faster than the tourism industry as a whole, earning over 60 billion.
deforestation causes a decrease in ecotourism and therefore decreases employment opportunities, meaning low SES do not experience the positive effects on their livelihood.
over 41 million people are employed in the informal forestry sector.
includes commercial collection of fuelwood + production of charcoal.
the practice of illegal logging may take place, further increasing the rates and magnitude of deforestation.
about 350 million people live inside or near forests worldwide + are largely dependant to varying degrees on these areas for their livelihood .
a loss of forests means that those depending on it for their timber, food, fuel, jobs and shelter experience the effects heavily.
around 1 billion people depend substantially on forests for their nutritional needs + food security.
including many in extreme poverty.
(fruits, nuts, leaves, honey, livestock)
a loss of forests increases rates on malnutrition and food insecurity, especially in poor communities who rely on forests for their livelihood.
about 60 million indigenous people are wholly dependant on forests, including a number of hunter-gatherer societies + farmer communities
maintain spiritual connection with their land.
loss of forestry mead s loss of animal species that make up the basis of hunters diet. agricultural communities may also struggle to farm.
