The document describes the use of a WEAP model and a 36-year remote sensing dataset (1984–2020) to analyze bofedales wetlands in Bolivia's Katari watershed. It identifies that while glacier retreat in the Cordillera Real is evident, bofedales currently show a greening trend potentially due to increased meltwater and higher temperatures, though long-term decline is expected as aquifer recharge drops. The study also notes that human activities, including overgrazing and mining-related groundwater extraction, are deteriorating wetland health.

The study establishes a nutrient mass balance for Pelican Lake, Manitoba, finding that the lake acts as a net sink for phosphorus and a net source of nitrogen. External nutrient loads are strongly linked to surface hydrology and agricultural land use, with internal recycling from sediments contributing significantly to phosphorus levels. The findings suggest that remediation should focus on high-agricultural sub-catchments and the regulation of the Pembina River inlet dam.

The document examines how increasing the Degree of Regulation (DOR) through hydropower dams in the Magdalena River Basin affects the Mompos Depression. While current regulation is low, the addition of 30 planned projects could increase the DOR from 5% to 30%, significantly altering seasonal and low flows critical for biodiversity. The analysis finds that these dams would not protect against extreme floods, as safety releases during peak flows are necessary, and that reducing lateral connectivity via levees could increase peak flows downstream in cities like Barranquilla.

The report identifies significant climate risks in the Yaque del Sur watershed, where high exposure to hurricanes, floods, and droughts intersects with high poverty and low adaptive capacity. Modelling suggests that by 2050, the annual water deficit could reach 519 million m3, threatening key crops like maize and tomatoes. While the Dominican Republic has established disaster risk and climate change frameworks, the report finds a lack of coordination between these structures and deficiencies in data sharing. Recommended priority actions include shifting to drought-resilient crops (sorghum and mangoes), increasing irrigation efficiency from 20% to 45%, and implementing payment for ecosystem services to promote reforestation in the upper watershed.

The report uses the Soil Water Assessment Tool (SWAT) and a lumped groundwater model to evaluate the Jaldhaka watershed's current hydrology and the effects of shifting land use or increasing groundwater pumping. It finds that while both a deforestation scenario and an electrification scenario increase rice production, deforestation significantly raises flood risks. Electrification increases productivity but may lead to groundwater depletion of up to 8 meters in downstream areas under a 100% adoption scenario, though this may be partially offset by induced recharge from perennial rivers.
