Cambios en la partición de flujos de agua en el Chaco Árido al reemplazar bosques por pasturas
A study in San Luis, Argentina, comparing native dry forests and pastures found that replacing forests with pastures reduces direct precipitation interception and increases surface runoff and potential soil-level evaporation. These changes suggest a reduction in transpirable precipitation and a higher risk of water erosion.

Mining and Human Rights Violations in Argentina
The statement details the impact of the extractive-export mining model in Argentina, highlighting the systematic suppression of community resistance through police violence and the criminalization of protest. It asserts that mega-mining projects violate constitutional rights to water and a healthy environment, while citing specific instances of arrests and raids in provinces such as Catamarca, La Rioja, and Tucumán.

Land use change in the Rio de la Plata Basin: linking biophysical and human factors to predict trends, assess impacts, and support viable land use strategies for the future
The project investigates the trade-offs between agricultural expansion and ecosystem services in the Rio de la Plata Basin, finding that crop expansion has significantly reduced soil carbon and that certain afforestation efforts have negatively impacted regional hydrology and water yield.

Crop water relations, bioenergy options and ecosystem services in the La Plata Basin
The report examines the ecohydrological impacts of agricultural expansion in the La Plata Basin. In the Pampas, it identifies optimal groundwater depths for corn, soybean, and wheat, and suggests that replacing pastures with annual crops increases flooding risk. In the Chaco-Espinal region, agricultural conversion has led to deep groundwater recharge, salt mobilization, and the emergence of 'new rivers'. In Paraguay, deforestation of the Atlantic Forest increased river water yield from 40% to nearly 70% of rainfall inputs. The report also argues that harvesting biomass from fire-prone dry forests for bioelectricity is more carbon-efficient than soybean biodiesel, which causes significant emissions due to land-use change.
