Forest Change

TRF – the importance?

http://travel.mongabay.com/pix/peru/aerial-rainforest-Flight_1022_1551.html


• Incredibly rich ecosystems – playing a fundamental role in the basic functioning of the planet

• Home to probably 50% of the world’s species – an extensive library of biological and genetic resources (the genetic bank)

• Helps maintain the climate – regulating atmospheric gases & stabilizing rainfall

• Protection again desertification• Provision of numerous ecological functions


• At least 32 300 ha – disappear every day from Earth

• At least another 32 300 ha – under forest degradation

• Several hundred species – lost to extinction (the vast majority: never been documented by science)

• Threat of global warming / climate change – more carbon is added to the atmosphere• More topsoil is lost to erosion


• According to FAO estimation:- 10.4 million ha of TRF were permanently destroyed each yea

r from 2000 to 2005- For primary forests, annual deforestation rose from 5.41 milli

on ha to 6.26 million ha in the same period- Primary forests are being replaced by less biodiverse plantati

on and secondary forests.- The significant increase in plantation forests, forest cover has

generally been expanding in N. America, Europe and China while diminishing in the tropics.

- The major causes of global deforestation: industrial logging, conversion for agriculture (commercial & subsistence), forest fires (often purposefully set)

Causes of Deforestation

• Clear-cutting for logging and pulpwood • Forest conversion for permanent agriculture (palm oil plantations, so

ybean fields)

• Large-scale shifting cultivation (i.e. slash-and-burn) where forest is not permitted to regenerate due to subsequent clearing

• Forest conversion for permanent pasture • Open pit mining and large-scale mining operations • Clear-cutting for charcoal production • Large roads and infrastructure projects • Wildfires that destroy the forest canopy • Dam construction • Volcanic eruptions • Chemical defoliants • Urban expansion

Causes of Degradation• Most forms of logging for timber harvesting, especially "selective logging" • Small-scale shifting cultivation (i.e. slash-and-burn) • Over-grazing • Small scale mining and associated pollution • Over-harvesting for fuel wood • Fragmentation from small roads • Wildfires that burn leaf litter and small plants but leave canopy trees intact • Over-harvesting of non-wood forest products (medicinal plants, foods, fibers

)

• Over-hunting • Invasive species • Oil pollution • Storm damage • Extreme drought • Air pollution and acid rain

• Nestle fiasco continues: Indonesian oil palm planters threaten boycott too(03/23/2010) Candy and food giant Nestle is finding itself between a rock and a hard place. The online campaign against Nestle continues: today protesters once again posted thousands of negative messages on the company's Facebook page, most demanding that Nestle cut out palm oil linked to deforestation from its products. At the same time, a new problem has cropped up for Nestle: Indonesian oil palm planters are threatening to boycott Nestle products. Proving that the issues surrounding oil palm and deforestation are nothing if not complex: Facebook protestors say they will boycott Nestle if it doesn't cut out all links to Sinar Mas, a company that Greenpeace has linked to deforestation, whereas the Indonesia Palm Oil Growers Association are preparing a boycott if Nestle stops buying from Sinar Mas, according to the Jaka

rta Post.


• A new world?: Social media protest against Nestle may have longstanding ramifications (03/20/2010) The online protest over Nestle's use of palm oil linked to deforestation in Indonesia continues unabated over the weekend. One only needed to check-in on the Nestle's Facebook fan page to see that anger and frustration over the company's palm oil sourcing policies, as well as its attempts to censor a Greenpeace video (and comments online), has sparked a social media protest that is noteworthy for its vehemence, its length, and its bringing to light the issue of palm oil and deforestation to a broader public.


• Scientists: new study does not disprove climate change threat to Amazon(03/19/2010) Recently, Boston University issued a press release on a scientific study regarding the Amazon's resilience to drought. The press release claimed that the study had debunked the Intergovernmental Panel on Climate Change's (IPCC) theory that climate change could turn approximately 40 percent of the Amazon into savanna due to declining rainfall. The story was picked up both by mass media, environmental news sites (including mongabay.com), and climate deniers' blogs. However, nineteen of the world's top Amazonian experts have issued a written response stating that the press release from Boston University was "misleading and inaccurate".


• Indonesia opens protected rainforests to mining and other developments(03/16/2010) Indonesian President Susilo Bambang Yudhoyono has issued new regulations, which will allow underground mining in protected areas, according to the Jakarta Post. The new rules will also allow power plants, renewable energy, and transportation such as toll roads in protected forests.
