Large-scale soy farming in Brazil pushes ranchers into the Amazon rainforest Rhett A. Butler, mongabay.com April 28, 2010 The research, which looked at soy and cattle dynamics in the southern Amazon stats of Mato Grosso and Pará, supports the claim that soy is an important indirect driver of deforestation in the world's largest rainforest. The authors — including Elizabeth Barona, Navin Ramankutty, Glenn Hyman and Oliver Coomes — analyzed annual census data on deforestation, crop harvest area, livestock population, and pasture area between 2000 and 2006 from municipalities in the Brazilian Legal Amazon. Their analysis found that deforestation shifted 39 km to the northeast during the period, while pasture shifted 87 km to the northwest, from northeastern Mato Grosso to southwestern Para, and soybeans moved 82 km to the northeast, from southern to northeastern Mato Grosso. The researchers also noted that soybean expansion was accompanied by a decline in pasture area in many municipalities in Mato Grosso, lending support to the argument that "decreases in pasture in Mato Grosso owing to soybean expansion may have been compensated by increases in pasture elsewhere in northern Mato Grosso, Para and Rondônia causing some deforestation indirectly, i.e., 'displacement deforestation.'"
The authors say future research should "examine more closely how interlinkages between land area, prices, and policies influence the relationship between soy and deforestation, in order to make a conclusive case for 'displacement deforestation.'" Soy in the Amazon Soy production in the Amazon exploded in the early 1990s following the development of a new variety of soybean suitable to the soils and climate of the region. Most expansion occurred in the cerrado, a wooded grassland ecosystem, and the transition forests in the southern fringes in the Amazon basin, especially in states of Mato Grosso and Pará — direct conversion of rainforests for soy has been relatively limited. Instead, the impact of soy on rainforests — as suggested by the Environmental Research Letters study — is generally seen to be indirect. Soy expansion has driven up land prices, created impetus for infrastructure improvements that promote forest clearing, and displaced cattle ranchers to frontier areas, spurring deforestation.
Nevertheless soy growers, crushers, and traders have taken steps to reduce the environmental impact of their crop in the Amazon biome. After a damaging Greenpeace campaign in 2006, leading players in the industry agreed to a moratorium on soy grown on newly deforested lands. Analysis last year showed that growers are mostly abiding by the ban: only 12 of 630 sample areas (1,389 of 157,896 hectares) deforested since July 2006 — the date the moratorium took effect — were planted with soy.

(02/08/2010) Business-as-usual agricultural expansion to meet biofuel production targets for 2020 will take a heavy toll on Brazil's Amazon rainforest in coming years, undermining the potential emissions savings of transitioning from fossil fuels to biofuels, warns a new paper published in the Proceedings of the National Academy of Sciences (PNAS). The research suggests that intensification of cattle ranching, combined with efforts to promote high-yielding oil crops like oil palm could lessen forecast greenhouse gas emissions from indirect land use in the region.
Concerns over deforestation may drive new approach to cattle ranching in the Amazon 
(09/08/2009) While you're browsing the mall for running shoes, the Amazon rainforest is probably the farthest thing from your mind. Perhaps it shouldn't be. The globalization of commodity supply chains has created links between consumer products and distant ecosystems like the Amazon. Shoes sold in downtown Manhattan may have been assembled in Vietnam using leather supplied from a Brazilian processor that subcontracted to a rancher in the Amazon. But while demand for these products is currently driving environmental degradation, this connection may also hold the key to slowing the destruction of Earth's largest rainforest.
Brazil could triple agricultural output without touching the Amazon rainforest 
(04/15/2009) Brazil could triple its agricultural without the needing to clear additional rainforest in the Amazon Basin, Roberto Mangabeira Unger, Brazil's Minister of Strategic Affairs, told Bloomberg in an interview. The argument that Brazil can expand its agricultural production without harming the Amazon is a mantra among Brazilian officials. The country has vast tracts of pasture and agricultural land that are being underutilized or have been abandoned, but rapidly appreciating land prices, coupled with poor governance and inconsistent enforcement of environmental laws, means that it is often more profitable to clear new forest land than to rehabilitate pasture.
Rainforest soy moratorium shows success in the Brazilian Amazon 
(04/15/2009) An industry-led moratorium on soy plantings on recently deforested rainforest land continues to show success in the Brazilian Amazon, reports a study released Tuesday by environmental groups and Abiove, the soy industry group that formed the initiative and represents about 90 percent of Brazil's soy crush. The satellite-based study showed that only 12 of 630 sample areas (1,389 of 157,896 hectares) deforested since July 2006 — the date the moratorium took effect — were planted with soy.
Brazil: 'Soy King', Environment Minister strike deal on Amazon deforestation (04/02/2009) Meeting at the Katoomba payments-for-ecosystem-services conference in Cuiaba, Brazil, Carlos Minc, Brazil's Environment Minister, and Blairo Maggi, Governor of the State of Mato Grosso and the world's largest individual soy grower, put aside their ideological differences and agreed to grant a temporary reprieve for ranchers and farmers in the Amazonian state, allowing them up to four years to reforest their holdings to bring them up to legal code. Under Brazilian law landowners in the "legal Amazon" are required to maintain 80 percent forest cover on their holdings, but in practice, the regulation is widely ignored.
