The IPBES catalogue of policy support tools and methodologies is an evolving online resource with two main goals. The first goal is to enable decision makers to gain easy access to information on policy support tools and methodologies to better inform and assist the different phases of policy-making and implementation. The second goal is to allow a range of users to provide input to the catalogue and assess the usability of tools and methodologies in their specific contexts, including resources required and types of outputs that can be obtained, thus helping to identify and bridge gaps with respect to available tools and methodologies.
