Cocaine Production Increases Destruction Of Colombia’s Rainforests

31.01.2011
Scientists from Stony Brook University are reporting new evidence that cultivating coca bushes, the source of cocaine, is speeding up destruction of rainforests in Colombia and threatening the region’s “hotspots” of plant and animal diversity. The findings, which they say underscore the need for establishing larger protected areas to help preserve biodiversity, appear in ACS’ journal Environmental Science & Technology.

Dr. Liliana M. Dávalos, professor in the Department of Ecology and Evolution at Stony Brook, and her colleagues note that the pace of deforestation in Colombia has accelerated over the past 20 years, even as population growth has slowed and the economy has shifted from agriculture to other revenue sources. This increase in deforestation overlaps with an increase in the cultivation of coca for cocaine production, and the country accounted for 75 per cent of the world’s coca in 2000.

Earlier reports found that direct deforestation from coca was surprisingly small, with as little as 150 km2 of forests replaced by coca each year by 2005. Since rainforests contain about 10 percent of the world’s plant and animal species — some of which become the basis of new medicines — deforestation represents a serious threat to global biodiversity. With studies suggesting that coca cultivation contributes indirectly to deforestation, the scientists set out to further document this impact.

Their analysis of data from 2002-2007 on the effects of coca cultivation on deforestation of rainforests in Colombia identified several factors that boosted the likelihood that rainforests would be destroyed. In southern Colombia, a forest close to newly developed coca farms, for instance, was likely to be cut, as was land in areas where much of the farmland was devoted to coca.

This is the first time the indirect impact on deforestation from cultivation destined for the global cocaine market has been quantified across South America’s biodiversity hotpots.

The Stony Brook University scientists also showed that designating protected areas, regions that are set-aside for special protection for environmental reasons, reduced forest destruction in coca-growing areas. Establishing larger protected areas in the region could help control deforestation and preserve biodiversity, the report suggests.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
