The document examines the relationship between soil microorganisms and plants, focusing on arbuscular mycorrhizal fungi (AMF). It argues that land-use and climate changes affect these microorganisms, which in turn impacts plant nutrition and agricultural yields. Findings indicate that AMF diversity and symbiotic capacity can decline during warm and dry seasons, potentially leading to a loss of the symbiotic relationship. In the páramos region, this research has been applied to create biofertilizers that increase potato growth in Bolivia and Ecuador.

The report evaluates floating treatment wetlands (FTWs) as a nature-based solution for eutrophication in shallow lakes. Through primary research at the IISD-Experimental Lakes Area (IISD-ELA) and a case study of Pelican Lake, Manitoba, the study demonstrates that FTWs—particularly those using cattails—effectively sequester phosphorus and nitrogen. While plant biomass contributes to nutrient removal, the report emphasizes that the microbial biofilm on roots provides up to 80% of the total treatment. For Pelican Lake, the study estimates that 5% surface coverage could reduce total phosphorus levels by 10% to 50%, though FTWs must be combined with watershed-level strategies to meet provincial water quality standards.

The research evaluates how numeric assertions and an 'estimation and reveal' technique influence the American public's perception of scientific agreement on human-caused climate change, finding both methods effective across different political ideologies.

Floating Treatment Wetlands (FTWs) are artificial platforms that enable aquatic plants to grow in deep water, utilizing a combination of plant uptake and microbial biofilms to remove pollutants. Research by the International Institute for Sustainable Development (IISD) demonstrates that FTWs can significantly reduce phosphorus levels, remove certain pharmaceuticals and herbicides, and potentially mitigate oil spills. The system is applicable to various freshwater environments, including lakes, stormwater ponds, and wastewater lagoons.

Researchers from the University of Cape Town developed insulated nest boxes to protect southern yellow-billed hornbills in the Kalahari Desert from extreme heat. The project found that insulated boxes significantly reduced nest temperatures, leading to higher fledging rates and healthier nestlings and females compared to uninsulated boxes.
