The study uses the Weather Research and Forecasting Model to simulate the impact of basin-wide agricultural expansion in the La Plata River basin. It finds divergent regional climate responses: the northern region experiences decreased temperatures and precipitation due to increased albedo and moisture advection, while the southern region sees increased temperatures and precipitation due to decreased albedo and altered moisture flux convergence. These changes also influence precipitation patterns over the South Atlantic Ocean.

The report examines how agricultural expansion and the proliferation of decentralized water storage, such as 'atajados' (artificial ponds), are altering the hydrologic balance in Bolivia's Chiquitano dry forest. Using remote sensing and field verification, researchers identified significant volumes of unmapped surface water storage and increasing groundwater extraction, which may reduce baseflows and threaten downstream ecosystems. The document argues that current hydrologic models lack this decentralized data and recommends improved regulation and monitoring of water use to support long-term planning.

The report examines seven transboundary river basins—Congo, Okavango, Red, La Plata, Danube, Mekong, and Jordan—to evaluate how ecosystem services (ES) are integrated into Integrated Water Resources Management (IWRM). It finds that while IWRM planning is common, actual implementation is weak and often focuses on traditional services like hydropower and navigation, neglecting critical ES such as carbon sequestration and flood regulation. The authors argue that moving toward an ES-based 'benefit-sharing' model, supported by economic instruments like Payments for Ecosystem Services (PES), can overcome political, institutional, and financial barriers to sustainable transboundary water management.

The document details the application of MODIS satellite imagery and automated algorithms to track land use dynamics in the La Plata River Basin. It focuses on the transition of agricultural frontiers—from deforestation to intensification—and the use of remote sensing to estimate evapotranspiration and water balance. A case study in Mato Grosso demonstrates how these tools can map the expansion of soybean and sugarcane, the adoption of double-cropping systems, and the resulting impacts on natural biomes like the Cerrado and Amazon forest.
