This research paper examines the hydrological impacts of replacing livestock systems (perennial alfalfa pastures) with grain production systems (annual crops) in the subhumid hyperplains of the Pampas in Argentina, finding that grain production increases water-table levels and flooding risks.

This case study describes the 'Pani Chautari' (water forum) process implemented by the Southasia Institute of Advanced Studies (SIAS) between 2016 and 2020 in Dhulikhel, Nepal. The initiative used evidence-informed, multi-stakeholder dialogues to address water scarcity and conflict, bridging the gap between scientific research and local policy-making to enhance urban water governance.

This report presents a Sustainable Asset Valuation (SAVi) assessment of three stormwater infrastructure options in the Paterson Park Precinct of Johannesburg, South Africa: a grey concrete culvert, a nature-based stream renaturalization, and a hybrid solution. Using data from the Copernicus Climate Change Service (C3S), the study compares these options through an integrated cost-benefit analysis (CBA) and climate change scenario analysis over 20- and 40-year horizons. The findings demonstrate that nature-based infrastructure is the most cost-efficient and climate-resilient choice, providing significant co-benefits in flood mitigation and water supply.

This report identifies and delineates Strategic Water Source Areas (SWSAs) for surface water and groundwater across South Africa, Lesotho, and Swaziland. It defines SWSAs as areas providing disproportionate runoff or high groundwater recharge that are nationally important for water security. The study identifies 22 national surface water SWSAs (SWSA-sw) and 37 national groundwater SWSAs (SWSA-gw), analyzing their contribution to urban centers, agriculture, and industry, while assessing threats from land-cover change, mining, and invasive alien plants.

This policy brief from the Stockholm Environment Institute and UNEP argues that traditional measures of 'water productivity' are too narrow because they often focus solely on agricultural output (e.g., 'crop per drop') while ignoring the essential role of landscape ecosystem services. The document advocates for an integrated water resource management (IWRM) approach that balances agricultural needs with the maintenance of natural water storage and ecosystem functions to ensure long-term sustainability and human well-being.

This working paper examines the relationship between urban expansion and the loss of natural infrastructure (blue-green cover) across India's 10 most populated cities between 2000 and 2015. Using remote sensing and satellite imagery, the study highlights how increased paved surfaces lead to reduced groundwater recharge and higher flood risks, recommending an integrated urban blue-green approach to planning to increase resilience.
