Historical State

The tropical savanna of Brazil, also known as the Cerrado, is the largest savanna in South America, covering over 20% of Brazil (WWF, 2013).  It is believed to have existed before South America and South Africa became two separate continents.  It is home to 1,600 species of animals and 10,000 species of plants (5,000 of which are endemic) (WWF, 2013).  Throughout the region, one can find animals such as jaguars, maned wolves, giant anteaters, giant armadillos, and marsh deer living amongst birds such as red-legged seriemas and Spix’s macaws (WWF, 2013).  Most of the plants survive both the wet and dry seasons and are well adapted to fire.  The Cerrado is so diverse that it has earned a spot on Conservation International’s “Top 25 Biodiversity Hotspots” list.  It is home to 5% of life on earth (WWF, 2011).

Before the modernization of Brazilian life, the Cerrado area was used very little by humans, mainly just for subsistence agriculture.  It was first colonized in the 1800s by explorers searching for gold and treasures.  The explorers settled down and became colonists, eventually setting up mainly cattle ranches.  Because of the high levels of aluminum found within the soil, the Cerrado contains soil that is relatively toxic.  The region was so irrelevant to Brazil that before the modernization happened in the 1950-60s, the Cerrado was known as the “wasteland” of Brazil.  As the modernization came about, scientists were encouraged to transform the Cerrado into an agricultural state - a feat that was accomplished by using large quantities of fertilizer, limestone, and water (Wolford, 2008).

Current Human Impacts



The Farming Impact on the Cerrado
(http://www.economist.com/node/16886442)
Before the 1960s, the Cerrado was not regarded as a valuable region, and was thus ignored for the most part.  Around this time, however, Brazil started building its new capital city, Brasilia. (AgBrazil, 2006).  The construction of Brasilia drew attention to the biodiversity hotspot.  Soon, large agricultural companies began raising livestock in the Cerrado.  In the 1970s, the Cerrado gained more unwanted attention when scientific developments led to more effective ways to grow crops in the somewhat difficult soil. Agriculture became a huge part of life within the Cerrado; large plantations started appearing in the area (AgBrazil, 2006).  Today, this widespread use of the land for agriculture has resulted annual emissions of 250 million tons of CO2 (WWF, 2011). As scientists managed to develop seeds better adapted for the tropical savannah climate, production skyrocketed - Brazil currently produces large amounts of soybeans.

According to the WWF, the Cerrado is the second most threatened area in Brazil (WWF, 2013).  A large part of this problem is due to agriculture.  The area has been developed, often using practices of monoculture, where farmers have soy plantations, cattle ranches, and burn sites for charcoal.  Unfortunately, the government of Brazil has done little to protect the region, and has even encouraged development.  Less than 3% of the land is under the protection of the law (WWF, 2013).  In addition, the biodiversity of the region is being depleted.  Currently, a mere 20% of the Cerrado’s vegetation remains (WWF, 2013).
The original vegetation of the tropical savanna is adapted to natural fires.  Currently, however, human-induced fire is often used to clear the land in the Cerrado to make it reusable for agriculture.  This burning creates “new growth,” which is used to feed cattle (WWF, 2010).  According to José Felipe Ribeiro, a Cerrado researcher, these unnatural fires allow non-native vegetation to spread: the wind blows the nutrients of these plants and replaces the nutrients of the native plants that were destroyed because of the fires. (WWF, 2010).

Future Prospects

Because the Cerrado is so heavily impacted by agricultural activities and urbanization, it is unlikely that the ecosystem can be maintained. The biodiversity within the Cerrado is rapidly being damaged as a result of current human impact.  Without government intervention, it appears as though it will only get worse.
According to a study by Wendy Jepson, “estimates of Cerrado vegetation loss speculate that modern agro-pastoral expansion has converted up to 80% of the savanna and that the pace of change is increasing” (Jepson, 2013).  Based on this study, it appears that this ecosystem will disappear altogether unless there is an intervention of sorts in the current practices being carried out on the land.

Although the Cerrado’s deforestation has been unnoticed for several decades, several organizations have begun to try and fix the problem through various methods. These same organizations have also been trying to get the Brazilian government involved in the problem with the Cerrado. Although only the slightest fraction of the land is protected by the government, this number is currently on the rise and hopefully in the future the government will protect a majority, if not all of the endangered land. Environmentalists and scientists have also suggested the cultivation of alternative crops that are able to better utilize the natural resources available in the Cerrado; this will hopefully minimize the negative human impact. Though unlikely, the preservation of the Cerrado is still feasible - a fact that the authorities should realize and work for (Wolford, 2008).



What Can Be Done...

The government of Brazil along with other international organizations such as the United Nations must work together in order to restore the Cerrado to its original state.  For example, the WWF is in the process of protecting what they refer to as “one of the world’s biological ‘hotspots.’”  To do so, they should continue to promote ecotourism.  This way, attention will be drawn to the region while it is simultaneously being preserved.  In addition, Brazil needs to become more active in the “Round Table on Responsible Soy,” which will help the nation develop more sustainable methods for the production of soy (WWF, 2013).  Other international organizations need to become more involved too by helping with the “Chapada dos Veadeiros National Park,” which is located in the center of Brazil (WWF, 2013).  The park’s territory should slowly be expanded in order to protect more of the Cerrado.
Furthermore, organizations such as the World Bank and the Climate Investment Funds must expand their efforts to assist residents of the Cerrado in the development of more sustainable working techniques.  Together, the two groups have already pledged $6.5 million (World Bank, 2013) to fund environmentally friendly activities.  In order to ensure that sustainable activities are continued, more organizations need to contribute not only their funds, but also their expertise; locals must be taught how to make a living without permanently damaging the Cerrado.
The government of Brazil also needs to work in conjunction with international organizations to create a set of stricter laws that will preserve what is left of the Cerrado, as well as begin to refurbish the land that has been destroyed.  If the Brazilian government continues to disregard the region, it will soon be taken over by large agricultural companies that will not work sustainably.
People who are not directly involved with the Cerrado can also help preserve the region by taking care to eat sustainably.  Agricultural demand is fueling the non-environmentally friendly methods of agriculture.  If the consumer were to put pressure on farmers to grow crops more sustainably by only purchasing certain goods, it is likely that the Cerrado will slowly return to the healthy biodiversity hotspot that it once was.

The data from the table above makes it clear how seriously the Cerrado is being threatened.  For instance, of the 438,910 km2 remaining, a mere 111,051 km2 is being protected.  In addition, the plant and animal species that are endemic to the are are being threatened.

Patterns of deforestation in the Cerrado also emphasize the danger that region faces.  From the chart above, it is clear that deforestation in the area has rapidly increased between 2002 and 2008.  If this destruction of the Cerrado continues at this pace, it is likely that the entire land will soon disappear.

Agricultural Production in Brazil (2009)
(http://www.abc.org.br/article.php3?id_article=778)
The chart shows the amount of agricultural production Brazil contributed to the world in 2009.  Brazil is within the top 5 exporting countries for each of the crops listed, meaning that agriculture has become a large part of the country’s income, and therefore its impact on the land has increased.
