The project establishes a Nitrogen, Society, and Environment Network (Nnet) to study the impacts of human activity on the nitrogen cycle across various Latin American ecosystems. It integrates empirical measurements of biological nitrogen fixation, atmospheric deposition, and fertilizer use with regional modeling to inform policy and environmental management.

The project aims to create a regional understanding of the nitrogen cycle in Latin America by measuring biological nitrogen fixation, atmospheric deposition, and the impacts of land-use changes. Initial findings include high nitrogen pollution in Venezuelan rivers, low biological nitrogen fixation in Chilean forests affected by copper mining, and the influence of urban and industrial areas on NOx concentrations in São Paulo. The initiative seeks to provide guidelines for policymakers to manage nitrogen and minimize environmental degradation.

The project assesses the effects of land use and cover changes on the La Plata Basin's hydroclimate, specifically focusing on the intensity and length of floods and droughts, as well as soil moisture, infiltration, and runoff. Using 1980-2005 datasets and a Weather Research and Forecast (WRF) modeling system, the research tests various land cover scenarios and introduces Ecosystem Functional Types (EFTs) to replace time-fixed land cover types in regional models.
