Lessons from the Nuestro Rio app: Reflections on exploring local perspectives on water quality in the Peruvian Andes

Scientific research around water security and water quality in the Peruvian Andes often excludes local perspective and knowledge, yet local water users not only directly depend on local water sources, but are also sensitive to changes in water availability, quality, and ecosystems over time. Increasing community involvement and representation is essential for improved understanding and more holistic, sustainable water resource management, however more participatory approaches with local communities often have a myriad of logistical and project constraints. Through a small GCRF funded pilot study, as part of an interdisciplinary and international research team we created and rolled out a smartphone photo elicitation app, “Nuestro Rio”, as a novel tool to gather insights into local perceptions of water quality in the Rio Santa basin, Peruivan Andes (2020-2022). Here we consider the ability of technological approaches such as our Nuestro Rio app to help address some key issues and improve research outcomes to the benefit of the research team and local communities, whilst reflecting on the challenges experienced. Sharing the lessons learnt from pilot projects like Nuestro Rio can help contribute to the growing dialogue on citizen science and participatory approaches, whilst also providing support and guidance for those currently planning or exploring similar research tools and projects.
