The Brazilian Pantanal is a 138,000 km2 tropical seasonal wetland located in the center of South America bordering Bolivia and Paraguay. The Pantanal contains approximately 1100 cattle ranches, 3 million cattle, 49,000 horses and a unique diversity of wildlife. Cattle ranching is the most important economic activity in the Pantanal. This study explores the(More)
Regional economic indicators and incentives for agricultural landowners in the Brazilian Pantanal were explored in order to understand better the observed increases in deforestation for the implantation of cultivated pastures to assist in the extensive management of beef cattle. About 95% of Pantanal lands are privately owned and about 80% are used as(More)

The financial impact of the first outbreak of Trypanosoma vivax in the Brazilian Pantanal wetland is estimated. Results are extended to include outbreaks in the Bolivian lowlands providing a notion of the potential influence of the disease and an analytical basis. More than 11 million head of cattle, valued at more than US$3 billion are found in the(More)
The last decade witnessed a manifest shift in the microprocessor industry towards chip designs that promote parallel computing. Until recently the privilege of a select group of large research centers, Teraflop computing is becoming a commodity owing to inexpensive GPU cards and multi to many-core x86 processors. This paradigm shift towards large scale(More)
The economic valuation of coral reefs ecosystem services is currently seen as a promising approach to demonstrate the benefits of sustainable management of coral ecosystems to policymakers and to provide useful information for improved decisions. Most coral reefs economic studies have been conducted in the United States, Southeast Asia and the Caribbean,(More)
Computer spreadsheets were developed to evaluate greenhouse gas (GHG) emissions from U.S. beef and dairy livestock systems from nine locations. Of the beef systems the cow-calf herd emitted the most and feedlot cattle the least methane (CH4) and nitrous oxide (N2O) per unit product. Carbon dioxide (CO2) emissions per unit product were the least for the(More)
1. Participatory research methodologies incorporating local knowledge are important to the success of ecological research and the sustainable management of natural systems. However, methods of this type are not commonly employed in the natural sciences. 2. We adopted a scienti®cally rigorous ethnographic research methodology to incorporate local knowledge(More)
In Costanza et al.’s famous Nature paper [Costanza, R., d’Arge, R, de Groot, R, Farber, S., Grasso, M., Hannon, B., et al. The value of the world’s ecosystem services and natural capital. Nature 15 (387), 253–260.] a value for the world’s ecosystem services is posited as a point of departure for further discussion. These calculations were re-estimated and(More)
This contribution discusses a multi-physics simulation engine, called Chrono, that relies heavily on parallel computing. Chrono aims at simulating the dynamics of systems containing rigid bodies, flexible (compliant) bodies, and fluid-rigid body interaction. To this end, it relies on five modules: equation formulation (modeling), equation solution(More)
