Although this cause-and-effect finding seems fairly straightforward, the issue of deforestation in the Amazon is more complex and more devastating than previously believed, said Marcelus Caldas, an assistant professor of geography at Kansas State University.
Caldas and his colleagues at the University of Texas at Austin and Michigan State University published their findings in a recent issue of the environmental science journal, Environmental Research Letters. Their study, "Statistical confirmation of indirect land use change in the Brazilian Amazon," looks at how mechanized agriculture in Brazil affects the country's forest in the Amazon, which is the second largest forest in the world.
Using data from 2003-2008, the team statistically linked the loss of forest area as the indirect effect of changing pastureland into space for soybean and biofuel crops in counties bordering the Amazon. Caldas, who grew up in Brazil, said this finding wasn't too surprising as most Brazilians are aware of the issue. What is shocking, however, is how much of an effect this is having on forests, he said.
"Between 2003-2008 soy production expanded in Brazil by 39,000 square kilometers," Caldas said. "Of this 39,000 square kilometers, our study shows that reducing soybean production by 10 percent in these pasture areas could decrease deforestation in heavily forested counties of the Brazilian Amazon by almost 26,000 square kilometers -- or 40 percent."
Caldas said he hopes this link between crops and deforestation will motivate Brazil's environmental policymakers to develop more dynamic agricultural regulations to slow deforestation.
Although the numbers and data back this connection, the notion that deforestation will cease completely is unlikely because of other complexities like money and livestock. Demand for Brazil's crops is high and there's a desire to produce more for buyers.

Preparing for the Geography Bee
The Geography Bee, more properly known as the National Geographic Bee, begins at the local level and winners work their way to the final competition in Washington D.C.
The Geography Bee begins in schools with students from fourth through eighth grade across the United States in December and January. Each school Geography Bee champion takes a written test upon winning the Bee in their school. One hundred school winners from each state proceed to the State Level Finals in April, based on their scores on a written test scored by the National Geographic Society.
The Geography Bee winner in each state and territory proceeds to the National Geographic Bee in Washington D.C. for a two-day competition in May. On the first day, the 55 state and territory (District of Columbia, the Virgin Islands, Puerto Rico, the Pacific Territories, and the overseas U.S. Department of Defense schools) winners are narrowed to a field of ten finalists. The ten finalists compete on day two and the winner is announced and wins a college scholarship.
What follows are my tips and techniques to help you prepare for the National Geographic Bee (formerly called the National Geography Bee but since the National Geographic Society is the organizer, they decided to change the name).
* Start with a world map, globe, and atlas and become very familiar with the continents, countries, states and provinces, islands, and major physical features of our planet.
* Use Outline Maps of the world and continents to test yourself on this information. Knowing the relative location of countries, islands, major water bodies, and major physical features is very important for the Bee. Be sure to also have a good understanding of where the major lines of latitude and longitude lie.
* Take as many practice quizzes as possible. My site offers an archive of hundreds of multiple-choice Geography Quizzes that will definitely help. National Geographic offers a daily GeoBee Quiz online. There are additional online quizzes in my Test Your Knowledge collection of resources. Be sure to use an atlas to look up or understand the questions that you've missed.
* Prepare flash cards or use some other technique to memorize the capitals of the countries of the world and the capitals of the fifty United States.
* Memorize these Basic Earth Facts, the Highest, Lowest, and Deepest points around the world, and study other geographic superlatives.
* Read the newspaper, news magazines, and subscribe to my free Geography Newsletter and Geography 101 Email Course to learn about geography and to stay up-to-date with major news events happening around the world. Some Bee questions come from the geography of current events and these events are usually those that occur in the latter portion of the year before the Bee. Look up any unfamiliar place names you encounter in an atlas.
* Knowing principal languages, currencies, religions, and former country names is definitely a bonus. It's most important at state and national levels. This information is best obtained from the CIA World Factbook.
* Become familiar with the terms and concepts of Physical Geography. If you can review the glossary and key concepts of physical geography from a college-level physical geography textbook, do so!
In the 1999 state finals, there was a difficult round devoted to exotic species but each question's answer was the choice between two places so having a good geographical knowledge would have been the easiest way to win the round. My book, The Geography Bee Complete Preparation Handbook: 1,001 Questions & Answers to Help You Win Again and Again!, is a helpful resource for those preparing for the Bee at the school, state, or national levels.
