Dissertation Biophysical Behavior in Tropical South America

OF DISSERTATION BIOPHYSICAL BEHAVIOR IN TROPICAL SOUTH AMERICA The concentration of CO2 in the atmosphere is rising, in response to human activities such as consumption of fossil fuel, cement production, and land cover change. This increase is mitigated by the fact that currently, approximately one-half of the CO2 of anthropogenic origin does not take up permanent residence in the atmosphere, b...

The Role of Tropical Cyclones in Precipitation Over the Tropical and Subtropical North America

Tropical cyclones (TCs) are essential elements of the hydrological cycle in tropical and subtropical regions. In the present study, the contribution of TCs to seasonal precipitation around the tropical and subtropical North America is examined. When TC activity over the tropical eastern Pacific (TEP) or the Intra Americas Seas (IAS) is below (abovenormal), regional precipitation may be below (a...

Assessment of 21 Century Climate Change Projections in Tropical South America and the Tropical Andes

Governance, agricultural intensification, and land sparing in tropical South America.

In this paper we address two topical questions: How do the quality of governance and agricultural intensification impact on spatial expansion of agriculture? Which aspects of governance are more likely to ensure that agricultural intensification allows sparing land for nature? Using data from the Food and Agriculture Organization, the World Bank, the World Database on Protected Areas, and the Y...
