Citizens AND HYdrology (CANDHY): on the application of a transdisciplinary framework for assessing citizen science projects addressing hydrological challenges

Abstract

<p>Earth and water monitoring and observation systems provide open geo data to scientists and professionals supporting distributed knowledge of major hydromet dynamics and extremes. Mobile technologies, at the same time, are empowering citizens who are nowadays informed and involved in volunteering actions designed and implemented to make our communities more safe and sustainable. Citizen science, as a consequence, is gaining momentum empowering the general public, from the “pleasure of doing science” to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water-related challenges. This work illustrates a conceptual transdisciplinary assessment model that was designed with the goal of standardizing the use of citizen science for advancing hydrology. This work was promoted by the Citizens AND HYdrology (CANDHY) Working Group established by the International Association of Hydrological Sciences (IAHS), and that is composed by a diverse group of hydrological, computer and social science experts. A community paper (Nardi et al., in press) presented the conceptualization of this transdisciplinary framework by identifying the shared constituents, interfaces and interlinkages between hydrological sciences and other academic and non-academic disciplines. Particular emphasis was given to the integration of human sensing and behavioural mechanisms into citizen science programs addressing hydrological problems. The proposed CANDHY transdisciplinary framework is here further tested and applied to assess some selected citizen science programs to understand the knowledge gaps and opportunities arising from ongoing citizen science programs. This comparative assessment shows some interesting preliminary results demonstrating the capacity of the proposed framework in homogenizing and accumulating knowledge from the collaboration of diverse participatory programs addressing similar or complementary hydrological challenges.</p><p> </p><p>Nardi F. et al., in press.
