From Forest to Field: How Fire is Transforming the Amazon : Feature Articles They pored over satellite images from the Landsat satellite captured between 1993 and 1995 to see what happened to all the area that was “deforested” in 1992. They decided that cleared areas with nice, straight lines that had sprung up next to pre-existing forest edges were probably intentional clearings for pasture or farmland. But Cochrane and his colleagues also discovered that much of the area labeled as deforested in 1992 was far from forest edges, was irregular in shape, and was already beginning to regrow. These areas, it seemed clear, were probably not the result of intentional deforestation. This distinction between accidental and intentional is important, explains Nepstad, because “it suggests that much of the impoverishment of the Amazon may have nothing to do with people’s plans for the land.” The impacts of fires during the 1997-98 El Niño were dramatic and easily visible in satellite imagery, leading to an overestimate of deforestation for that time period.
Forest Bump - By Charles Kenny Fewer jobs, dwindling savings, piles of public debt -- there's not much reason to be thankful for the global recession. But one small silver lining is that it has slowed the rate at which we're turning the atmosphere into an over-amped electric blanket. There are two things at work here: First, less growth slows the demand for energy. The second reason environmentalists can feel good about a recession is that lower demand for everything -- including wood and agricultural products -- reduces the incentive to chop down trees. Tropical forests are home to about half of all species on Earth. A tool developed by my colleague David Wheeler at the Center for Global Development called FORMA (or Forest Monitoring for Action) allows close tracking and analysis of global deforestation trends. That change was largely thanks to a considerably slowed rate of clearing in Indonesia and Brazil, which between them account for over three quarters of tropical deforestation.

Deforestation The Double Whammy of Deforestation Deforestation by burning, a widespread practice in the world’s tropical rain forests, adversely impacts the trace-gas composition of the atmosphere in two different ways. First, the burning of the tropical forests produces large amounts of carbon dioxide, carbon monoxide, methane, and other trace gases that are products when biomass burns. Second, the tropical forest is an important sink, or repository, for carbon dioxide. Atmospheric carbon dioxide is incorporated into the living biomass via the process of photosynthesis, which in turn produces the oxygen we breathe. The Past Much of the Earth was once covered by trees, but the majority of these were cleared long ago to make way for an ever expanding human population. People have been living in and around tropical rain forests for tens of thousands of years, taking what they needed from the wealth of natural resources available without compromising their environment.
Amazon Destruction Amazon Destruction Since 1978 over 750,000 square kilometers (289,000 square miles) of Amazon rainforest have been destroyed across Brazil, Peru, Colombia, Bolivia, Venezuela, Suriname, Guyana, and French Guiana. Why is Earth's largest rainforest being destroyed? For most of human history, deforestation in the Amazon was primarily the product of subsistence farmers who cut down trees to produce crops for their families and local consumption. The result of this shift is forests in the Amazon were cleared faster than ever before in the late 1970s through the mid 2000s. But that trend began to reverse in Brazil in 2004.

International Deforestation and Climate Change: Statement for the record by US Assistant Administrator for Economic Growth, Agriculture and Trade Foreign Relations Committee United States Senate Mr. Chairman, I appreciate the opportunity to submit a statement for the record on this important topic. Tropical forests are critical to the survival and well-being of people around the world. Unfortunately, tropical forests face a number of threats, including conversion to agriculture, illegal logging, unsustainable extraction of timber and other forest resources, climate change, pollution, and policies that subsidize forest conversion to other uses. To address these concerns and to ensure that forests and biodiversity continue to play an important role in sustainable development, USAID supports programs around the globe that aim to improve the conservation and sustainable management of forests and biodiversity. I would like to highlight for the Committee some of the key U.S. efforts in this area. Activities I would like to highlight include: Mr. Activities in the forest sector address forests and climate change strategically.
Live Science: Deforestation Deforestation is the permanent destruction of forests in order to make the land available for other uses. An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations' Food and Agriculture Organization (FAO). Some other statistics: About half of the world's tropical forests have been cleared (FAO) Forests currently cover about 30 percent of the world’s land mass (National Geographic) Forest loss contributes between 6 percent and 12 percent of annual global carbon dioxide emissions (Nature Geoscience) About 36 football fields worth of trees lost every minute (World Wildlife Fund (WWF)) Deforestation occurs around the world, though tropical rainforests are particularly targeted.

How to Fight Deforestation With Your Fork Can going meatless once a week change the course of our rainforests? Let’s look at what, why and how. Today, the raising of livestock uses 30 percent of the Earth’s total land surface. We simply can’t afford to lose our rainforests. Simple truth: As the world population explodes and the demand for meat grows, more and more rainforest will be destroyed. Why? Peggy Neu, president of the Monday campaigns, reminds us that Meatless Monday has its roots in World War I and II, when Americans were asked to help conserve key staples to aid the war effort.

Deforestation – World Socialist Movement You can't assume that because something is forbidden, it isn't going to happen.(1) These were the words of President Candoso of Brasil after the announcement of record high levels of deforestation in the Amazon, up 34% since 1991. The history of international attempts to prevent the destruction of forests supports these words. Deforestation rates The world's forests are important for many reasons—from regulating climate to providing a habitat for the majority of species on earth. There are two types of forest—temperate and tropical. Yet the global rate of tropical forest destruction is increasing. Only a very small proportion of the world's tropical forests are managed sustainably, so as to ensure that trees are not felled at a rate exceeding the capacity of the forest to grow back. Causes It is clear from the very fact that deforestation has taken place on such a huge scale that ecological sustainability has not been given priority. Attempted Solutions: International Agreements However,
Deforestation A deforested area Deforestation is when forests are lost and not replanted. Sometimes deforestation happens when people change the land into farms, ranches and cities. A lot of deforestation is from removal of all the trees from a forest for wood or fuel. The opposite of deforestation is afforestation. Cause of deforestation[change | edit source] Deforestation is the removal of trees for requirements of growing population. Forests have the following functions:- regulation of the water cycleproduction of soilprovide habitat for animalsprovide most of our oxygenmaintain the oxygen and carbon dioxide balance in the atmosphereregulation of temperatureprevent soil erosion There are many reasons for deforestation like logging where people cut down trees for money because they have to feed their families Forests are often planted to protect against natural disasters. Trees are also important for storing carbon. Other websites[change | edit source]
Cheetos in crosshairs of deforestation controversy - Mar. 30, 2016 SumOfUs, an online consumer advocacy group, launched a campaign against Cheetos saying that its palm oil policy doesn't go far enough to ensure that it is deforestation-free. Palm oil has been a problematic ingredient, because it is often obtained by clearing rainforests, according to the World Wildlife Federation. That has threatened the habitats of many endangered species, including elephants, orangutans, rhinoceroses and tigers. Cheetos maker Frito-Lay, a subsidiary of PepsiCo (PEP), has committed to using sustainable palm oil that is grown on plantations -- not in rainforests. But that pledge doesn't take full effect until 2020. Yet SumOfUs has called PepsiCo's commitment "weak," criticizing Pepsi for its lack of enforcement. "PepsiCo's palm oil policy is a step in the right direction, but it doesn't really do enough to prevent deforestation," said Katherine Tu, campaign leader at SumOfUS. A spokeswoman for Pepsi denied that IndoFood was excluded from its palm oil pledge.
Saving the Amazon: Winning the war on deforestation 2 January 2012Last updated at 00:55 By Justin Rowlatt BBC News, Amazonia For years, the story told about the Amazon has been one of destruction - the world's largest rainforest, a region of amazing biodiversity, key to the fight against climate change, being remorselessly felled. But that is no longer the whole truth. The Environment Agency special ops team gathered in a sultry town right on the southern edge of the Amazon. These aren't bureaucrats with crumpled suits and clipboards. These officers are, as I was to discover, soldiers on the front line in what Brazil regards as a war - a war to protect the Amazon rainforest. I'd been invited along on one of the agency's routine raids in the jungle. On a map pinned to the wall, three commanders were working out strategies and logistics, just like a military operation. "Are the loggers likely to be armed?" "Don't worry about guns," said the lead officer, Evandro Selva. Nothing serious? River turtles hatch and then head off to 'nursery' Hope
