One of the primary objectives of this project is to promote the widespread adoption of nature-based solutions (NbS)  for water treatment in the Philippines, Sri Lanka, and Vietnam. By doing so, we aim not only to provide valuable insights to various stakeholders regarding the current state of these treatment systems but also to underscore the importance of replication and encourage their implementation and further collaborations. Furthermore, this initiative can serve as a powerful tool for enlightening decision-makers about the existing status of NbS and garnering their support for the replication process.

To facilitate easy identification of NbS structures, our project has devised two distinct approaches utilizing Google Maps (Fig.1 ) and Geographic Information System (GIS) (Fig.2). These approaches enable stakeholders to swiftly pinpoint the precise locations of NbS installations with relevant information, such as implementing agency or owner, date the project was established, description of the project, and design parameters or performance as measured by effluent quality. Detailed methodologies for these approaches are elucidated in Chapter 2 of the project’s guidebook (Velasco et al. in press). The generated maps come in both static and dynamic formats, allowing for the convenience of printouts and interactive use, respectively.
