About Nature-based Solutions 

Nature-based Solutions address societal challenges through actions to protect, sustainably manage, and restore natural and modified ecosystems, benefiting people and nature at the same time.  

They target major challenges like climate change, disaster risk reduction, food and water security, biodiversity loss and human health, and are critical to sustainable development.   

The design, implementation, and evaluation of Nature-based Solutions are supported by the IUCN Global Standard for Nature-based Solutions. The Global Standard helps users shape their solutions and make them truly effective through 8 criteria and 28 indicators, supported by guiding questions.

Our work

IUCN pioneered the concept of Nature-based Solutions 20 years ago, first formulating a formal definition of NbS, then developing a rigorous standard to inform the design, implementation and evaluation of interventions: the IUCN Global Standard for Nature-based Solutions.   


The Global Standard for NbS is accompanied by a guide and an online self-assessment tool


The IUCN NbS Management Hub supports governments to mainstream NbS in national policies and strategic plans and helps communities and non-governmental organisations to improve actions on the ground.  


IUCN’s work on Nature-based Solutions is governed by IUCN’s International Standard Committee and is supported by experts from the IUCN Commission on Ecosystem Management (CEM) and its NbS Thematic Group


The Union offers stakeholders from all sectors the opportunity to learn how to apply Nature-based Solutions in their professional context through a Professional Certificate on NbS. This online course is offered by the IUCN Academy
