Within the network, the present side project is carried out by Leibniz University Hannover, Institute of Botany together with the research centre l3S by a) advancing the further development of the platform and thus contributing to a better understanding and applicability of NbS in the various stakeholder contexts and b) participating in the collection of high-quality data. 

The Constructed Wetlands Knowledge Platform (CWKP), the main outcome of this project, will be a holistic web tool developed with the help of stakeholders. Stakeholders include communities, wastewater producing businesses, farmers, fishermen, sellers of agricultural products, cooperatives, consumers, etc. The platform can thus systematically summarize information on CWs that has been compiled with great expertise and is therefore relevant for decision-making. It is planned to link this globally unique complex source of information with the ongoing monitoring and reporting efforts of SDG6 custody organizations such as UN-Habitat and WHO for SGD 6.3.1 - Wastewater Treatment.

As a by-product of the participatory character of the project, the consortium partners also expect that the benefits of NbS and the high effectiveness of CWs for sustainable wastewater treatment can be communicated more widely and knowledge-based to more actors*, thus increasing the willingness to implement such projects. The guidelines, documentation and information materials made available on CWetlands can also make a significant contribution to raising awareness of NbS and its potential, thereby contributing to a more sustainable future, especially for the people living in CELAC cities.
