Floods, Droughts and Farming on the Plains of Argentina and Paraguay, Pampas and Chaco Regions

The Pampas in Argentina and Chaco in Paraguay constitute one of South America's most important global grain suppliers. The rapid expansion of crops over pastures (Pampas) and forests (Chaco), combined with climate change and an extremely flat topography, make these regions vulnerable to unpredictable hydrological shifts. In Chaco, drought is the primary short-term concern, whereas in Pampas, the predominant risks are flooding and soil salinization. Given the importance of agriculture in the two areas, vulnerability to climate change events poses an urgent challenge to both rural and national economies.

This grant will enable a team of scientists from the two countries to explore the reciprocal links between climate change, land use, farming decisions, and surface and groundwater hydrology at scales ranging from the small plot to the river basin. Researchers will apply a mix of methods, including remote sensing, field observation, hydrological and agricultural modeling, farmer interviews and participatory data gathering involving farmers. Then, they will design and test land use planning tools at the most local level of government (county), the level at which different stakeholder interests are best mediated. The project will also serve as a training ground for several graduate students from the two countries. Other outputs will include peer-reviewed publications, policy briefs and bulletins for farmer associations.
