Towards the Constructed Wetlands Knowledge Platform for sustainable development

Publishable summary: 

80% of all wastewater worldwide is released untreated into the environment, leading to deteriorating water quality. Achieving universal access to sanitation while improving water quality by halving the proportion of untreated wastewater and increasing its safe reuse are targets 6.2 and 6.3 of the Sustainable Development Goals (SDGs). Constructed Wetlands (CWs), a Nature-based Solution (NbS), can contribute to these targets. Currently, there is little knowledge about the contribution of CWs to the global amount of treated wastewater. UNUFLORES has initiated the process of establishing a global Constructed Wetlands Knowledge Platform (CWKP). As a first step, a user requirements analysis was carried out through a twostep expert survey distributed globally through social media and target networks. This allowed defining key parameters, information and functions to be implemented in the platform. From this, a preset data infrastructure, highlighting about 70 CWs parameters, was derived and implemented in a pilot level GIS based platform In collaboration with CentroGeo.
