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.","ai_generated":true,"unit":"sei-001140#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Agricultural expansion and urban development in the Chiquitano dry forest are driving significant land use changes, including increased deforestation.
