As water funds and other watershed investment programs expand around the world, there is growing interest in designing equitable programs that provide both upstream and downstream benefits. While research demonstrates that diverse values underlie upstream participation, existing communication and outreach materials from nonâgovernmental organizations (NGOs), governments, development banks, and others tend to highlight the goals of downstream actors (e.g., improving water supply for cities), with little attention to upstream perspectives. We present a case study in response to this gap, where we collaborated with a water fund and a river users association in Colombia to coâproduce a website entitled âPutting Suppliers on the Mapâ in which interviews and photography illuminate the perspectives of upstream participants and the intermediary organization. The website offers multiple lessons for communication and environmental education in water funds by shifting focus to the motivations of upstream participants, including trustâbuilding among upstream and downstream participants via intermediary actors, and informing downstream water users of the essential role of these processes for program success. Analyzing the website testimonials, we show that the vast majority of participants were motivated not only by overlapping instrumental and relational values associated with conservation, but also by a variety of personal and community goals. We found that the largest barrier to participation over time was the need to build trust between the water fund and rural communities and to align water fund goals with participants' motivations. By making visible the motivations and challenges of upstream actors, the website reverses the standard direction of environmental education (in which highâlevel actors or downstream groups educate upstream residents). Inâsoâdoing, the website aims to help downstream actors envision more productive and equitable ways of interacting with upstream participants.
