This edition of Hydrolink brings to you a taste of different Nature based Solutions employed for water management from around the world, ranging from examples in upstream catchments and streams, large rivers, urban areas, and coastal zones. It is written by members of the IAHR NbS Working Group which was established at the 39th IAHR Congress in Granada (Spain) in 2022 which is rapidly growing and gaining momentum, with presence not only during the World Congresses, but also in other IAHR conferences such as the RiverFlow 2024 conference in Liverpool and the ISEH 2024 in Aberdeen. In all of these events we aim to bring together people with a shared passion to improve water management in a sustainable way, working with nature rather than against it.
This edition comprises of six articles, five of which focus on their use in wetland, riverine and coastal settings, and illustrate their potential effectiveness to provide flood and drought resilience to communities while providing a plethora of other environmental and societal benefits. The examples given in these articles show that care needs to be given to good monitoring and modelling for a sound understanding of the functioning of these measures under a wide variety of hydro-meteorological events. An essential ingredient of what makes a scheme successful is the involvement of all stakeholders in its co-design and adoption. The sixth and final article  focuses on the role and benefits of community involvement in a scheme in South-West Uganda for managing drought and providing food security in agricultural production. One thing we, as a community of researchers and practicing engineers can further improve on is a wider more integrated assessment of all types of proposed measures, both green and grey, on their impact on co-benefits such as biodiversity, water quality, socio-economic aspects, and human well-being.
