Last of the Amazon - National Geographic Magazine - 0 views

  • Brazil’s dilemma: Allow widespread—and profitable—destruction of the rain forest to continue, or intensify conservation efforts.
  • The market forces of globalization are invading the Amazon, hastening the demise of the forest and thwarting its most committed stewards.
  • n the past three decades, hundreds of people have died in land wars; countless others endure fear and uncertainty, their lives threatened by those who profit from the theft of timber and land. In this Wild West frontier of guns, chain saws, and bulldozers, government agents are often corrupt and ineffective—or ill-equipped and outmatched. Now, industrial-scale soybean producers are joining loggers and cattle ranchers in the land grab, speeding up destruction and further fragmenting the great Brazilian wilderness.

  • All of it starts with a road. Except
  • nearly every road in the Amazon is unauthorized. There are more than 105,000 miles of these roads, most made illegally by loggers to reach mahogany and other hardwoods for the lucrative export market.
  • In Brazil, the events set in motion by logging are almost always more destructive than the logging itself.
  • squatters, speculators, ranchers, farmers, and, invariably, hired gunmen.
  • . Land thievery is committed through corruption, strong-arm tactics, and fraudulent titles and is so widespread that Brazilians have a name for it: grilagem,
  • landless squatters moved in from adjacent lots, working plots whose ownership the government failed to resolve. That has fueled a bloody showdown pitting the powerful absentee elites who raze forest for agribusiness against family farmers who clear small patches for crops but still depend on intact forest around them for survival.
  • The first model was implanted during the military dictatorship, based on timber extraction and cattle. It’s predatory because it causes death, it’s not renewable, and it devastates the forest.” The alternative model, preached by Stang, is what Pontes calls social environmentalism. The first concentrates wealth, the second calls for its dispersion in small-scale agroforestry collectives.
  • Stang saw human rights and environmental conservation in the Amazon as inextricably intertwined
  • To Maggi, deforestation is an overblown issue, a “phobia” that plagues people who can’t grasp the enormity of the Amazon. “All of Europe could fit inside the Amazon,” he says, “and we’d still have room for two Englands.”
  • “Look around,” he said, “you won’t find a single scrap of plastic here.” Motioning to a barnlike structure that stored herbicides and pesticides, he said, “We keep all our agrotoxins properly ventilated until use.” In a steady rain, our vehicle fishtailing in the mud, we approached a denuded gully straddling a narrow stream; a closer look revealed hundreds of saplings. “When we bought this property,” Maggi said, “this riverbank was totally stripped. Now we’re regenerating the area.”
  • The land here is very poor. If you don’t take the right corrective measures, you couldn’t produce anything. It’s not true that soy degrades the soil. On the contrary, it puts into the soil what naturally isn’t there. Afterward, you can grow anything you want.” R
  • searchers agree that proper management of soy fields can increase soil productivity. But in reality, no one knows for sure how long the thin, highly acidic Amazon soils can be propped up, raising the possibility of an eventual two-headed catastrophe:
  • shiny new silos belonging to ADM, Bunge, and Cargill—all American multinationals.
  • azilians are not the only people profiting from soybeans. Along the 500-mile paved stretch of BR-16
  • between Cuiabá and Guarantã do Norte, there are no fewer than five John Deere dealerships. And at harvest time, fleets of the trademark green-and-yellow combines rumble across the fields flanking the highway, pouring rivers of golden soy into open-bed trucks bound f
  • The new district adds to an expanded mosaic of parks, reserves, and conservation units that, together with indigenous territories, forms the bulwark of defense against the expansion of the frontier in the central Amazon. These measures may be paying off. Deforestation rates fell more than 30 percent in 2005, and preliminary numbers for 2006 are also down. Indian lands in the Xingu watershed are proving an especially effective barrier. There, militant Kayapó and Panará warriors armed with clubs and shotguns patrol their borders using satellite images furnished by international NGOs to pinpoint illegal clearing. As Stephan Schwartzman puts it: “Where Indian land begins is where deforestation ends.” But Brazil’s measures to protect the Amazon must be weighed ag
  • These include plans to build seven dams on the environmentally sensitive Xingu and Madeira Rivers,
  • he dams will power aluminum smelters, and shipping channels will facilitate river transport of exports to Chinese markets.
  • s well as roads, power lines, oil and gas pipelines, and large-scale mining and industrial projects.
  • The dams will also flood millions of acres of forest, releasing methane and other greenhouse gases, destroying biodiversity, and forcing indigenous communities to flee ancestral lands.
  • Water cycling
  • carbon sequestering
  • maintenance of an unmatched panoply of life.
  • It’s far more profitable to cut it down for grazing and farming than to leave it standing. “Tropical deforestation is a classic example of market failure,”
  • “It’s urgent to find mechanisms to compensate forest peoples, and their governments, for the ecosystem services their forests provide.”
  • Last summer, Cargill and Brazil’s other big soy traders agreed to a two-year moratorium on buying soy grown on newly deforested land in the Amazon. The agreement is sending a signal to soy producers that the environmental impact of their operations is increasingly important in the world marketplace.

The Brussels attack is giving way to a terrible isolationist sentiment. - 0 views

  • nstead of calling for solidarity against a common threat, a spokesman for the anti-European U.K. Independence Party declared that the open borders of Europe “are a threat to our security,” even though the U.K. is not part of Europe’s Schengen border treaty.  A columnist for the Daily Telegraph declared Brussels the “jihadist capital of Europe,” and mocked those who call for staying in the EU on the grounds of safety. Meanwhile, American news organizations fell over themselves to get instant reactions from Donald Trump, who had just told the Washington Post that he didn’t see the point of NATO, which “is costing us a fortune.” He didn’t disappoint: “[W]e have to be very careful and very vigilant as to who we allow in this country.”

  • Every terrorist attack on U.K. soil in recent memory was carried out by British (or Irish) citizens and not foreigners; nuclear deterrence requires allies and coordinated responses; barbed wire cannot stop a cyberattack. The small-minded, short-sighted isolationists ignore reason and logic, instead substituting panic and fear.
  • Of course there are reasons for this change: German Chancellor Angela Merkel’s disastrous decision to apparently “invite” Syrian immigrants into Europe last summer has left many Europeans feeling queasy and out of control.
  • The only way to fight jihadism is through our existing military, economic, and political alliances
  • And the only way to ensure that we have international support in the future, when a tragedy takes place on our soil—and it will—is to offer our support for a tragedy unfolding on allied soil right now.

Admit it: we can't measure our ecological footprint | New Scientist - 0 views

  • “when humanity exhausted nature’s budget for the year” and began “drawing down local resource stocks and accumulating carbon dioxide in the atmosphere”. This year it was on 20 August, the earliest date yet.
  • “so misleading as to preclude their use in any serious science or policy context,” it says in a paper in PLoS Biology.
  • The footprint analysis does not really measure our overuse of the planet’s resources at all. If anything, it underestimates it.
  • ...5 more annotations...
  • It does this by measuring the productive land and sea area available – cropland and pasture, forests and fishing grounds – and matching that against the demands placed on them. This biological accountancy system concludes that planet Earth has a biocapacity of 12 billion hectares, and a human demand equivalent to 18 billion hectares. Hence the 1.5 Earths figure. Our footprint is 50 per cent too big.
  • I had assumed that the analysis assessed the damaging environmental consequences of how we use the land – things like soil erosion and the overuse of water reserves. But no. It only measures land area.
  • “Local ecosystem abuse is a significant problem [but] to make reliable adjustments would require data sets that do not exist,” he writes. Or, as he told me: “Our current accounts cannot include soil erosion. Hence cropland use equals cropland availability.”
  • It uses UN statistics to compare the timber we harvest against annual growth. The conclusion is that, while we are deforesting some areas, growth elsewhere more than makes up for the loss. This is reflected in a surplus in the accounts.
  • If the calculation is to be believed, while some fish stocks are being over-exploited, a greater number are under-exploited and overall fish biomass is increasing. That’s another surplus

  • eorge W. Bush was installed as President soon afterwards, and announced that he was pulling the US out of the deal altogether. Since the US is the source of a quarter of emissions of greenhouse gases that was a big blow, but the other nations decided to carry on and they finally reached agreement in Marrakech in November 2001.

  • qualify for carbon credits by planting forests that soaked up CO2.
  • It was finally agreed that countries will be able to claim some carbon credits for planting forests in developing countries. And they will also be able to allow countries to claim credit for activities such as soil conservation, which will allow more carbon to be soaked up in soils.
  • carbon trading
  • But the fear is that some countries may find themselves with spare credits to sell just because their economies have slowed down, which would undermine the whole purpose of the protocol.

  • But sceptics still see hot-air trading as a Trojan Horse for undermining the protocol.
  • lean Development Mechanism. This allows industrialised countries to claim credit for various activities in developing countries. It could become a major engine for getting clean energy technologies into poorer countries, so heading them off the dirty path to industrialisation that the rich nations took.

  • he protocol allows industrialised countries to plant “carbon sink” forests in the tropics, for instance, where they will grow faster. They can also invest in clean energy technologies in the developing world, and claim carbon credits for doing so.

  • Cutting emissions by 60 per cent is a suggested figure.
  • The Kyoto Protocol was drawn up with the long term as the primary focus. In essence, the protocol assumes that what we really need to worry about is the climate in a century’s time, not today.
  • CO2 sticks around for about a century. Methane, the second most important greenhouse gas, generally lasts in the atmosphere for about a decade. But while it’s there it is many times more potent.
  • This “hundred-year rule” has the effect of downgrading the importance of methane, and giving only small credit to countries that try to cut methane emissions.
  • the protocol gives a country that reduces its methane emissions by a tonne 20 times as much credit as for reducing CO2 emissions by a tonne.
  • Cows can be given less gas-inducing feed. Leaks in gas pipelines can be plugged. And so on.
  • Technically, we are going to have to find many more ways of producing energy without burning fossil fuels – the so-called carbon-free economy. Politically, we are going to have to find a way of doing so which doesn’t affect the growing economies of the developing nations, whose responsibility for the build-up of greenhouse gases so far has been minimal. Some people think this will require moving towards equal pollution rights for every citizen on the planet, a policy endorsed by Britain’s Royal Commission on Environmental Pollution earlier this year.

'Surprise' Palu tsunami clue found on seafloor - BBC News - 0 views

  • he quake occurred on what is called a strike-slip fault, where the ground on one side of a rupture moves horizontally past the ground on the other side. It is not a configuration normally associated with very large tsunamis.
  • When we overlap the bathymetric data from before and after, we can see that almost all of the area of the seafloor inside the bay subsides. And from this data, we can also observe [the movement] to the north. So, actually, we have a vertical and a horizontal displacement,

  • Palu witnessed a lot of liquefaction, where the structure of soils in the city was seen to collapse, to become fluidised and flow even on very low gradients.
  • That basically leaves no time for warnings. That's very different from Japan (in 2011) where there was an eternity of time - more than 30 minutes everywhere until the first person was killed by the tsunami. That's the challenge for these local tsunamis: people have to self-evacuate."
