The interface between agriculture and ecology in the Pantanal: a delicate balance
Written by: Molly Murphy, John Pritchett, Justin Cavitt, Wagner Ioshida
The Pantanal, an alluvial plain in southwestern Brazil bordered by the countries of Bolivia and Paraguay, is the home to a plant and animal community paralleled in its richness and diversity only by the African savannah. The region is also home to an extensive cattle herd, numbering approximately 3 million head. Pantanerios (people native to the Pantanal) have been grazing cattle in this region for generations, with the help of a breed of horse specially bred for the purpose of moving cattle long distances through the often boggy, flooded terrain.
Cattle agriculture is one of the main economic activities in the Pantanal. Cattle are often herded very long distances as they move to non-flooded areas.
Fishing is another major economic activity in the Pantanal. The rivers contain abundant fish and the environment must be protected to ensure continuing survival and high yields.

Although the Pantaneiros live in harmony with the ecosystem of the Pantanal, the need for economic development is clear. However, the generation of the resources necessary to bring basic services such as schooling and medical care to the people on the rural fazendas (farms) also brings the potential of ecological damage to the region. Development around the perimeter of the Pantanal has already begun to change the character of the land.
The Pantanal occupies a geological basin, which is a part of the course of the Rio Paraguai, and lends itself to the collection of runoff waters from surrounding areas. The cyclical flooding and recession of the waters concentrates not only diverse fauna, but also potentially harmful chemicals generated in farming and mining pursuits. Agriculture has changed the course of rivers feeding into the Pantanal; the long-term effects of these diversions (such as erosion) have yet to be determined.

Humans have been a part of the Pantanal ecosystem for many generations, and are reliant upon its abundance for their livelihoods. The Pantaneiro recognizes that the health of the ecosystem is crucial for the maintenance of his livestock, and his way of life. However, the voice of this rural minority may be in direct conflict with governmental and corporate interests. Decisions pertaining to development in the Pantanal will need to be made very carefully, with consideration of the needs of both humans, and the ecosystem upon which they thrive.
