Abstract
Intermittent rivers and ephemeral streams (IRES) are now recognized to sup- port specific freshwater biodiversity and ecosystem services and represent approximately half of the global river network, a fraction that is likely to increase in the context of global changes. Despite large research efforts on IRES during the past few decades, there is a need for developing a systemic approach to IRES that considers their hydrological, hydrogeological, hydraulic, ecological, and biogeochemical properties and processes, as well as their inter- actions with human societies. Thus, we assert that the interdisciplinary approach to ecosystem research promoted by critical zone sciences and socio- ecology is relevant. These approaches rely on infrastructure — Critical Zone Observatories (CZO) and Long-Term Socio-Ecological Research (LTSER) platforms — that are representative of the diversity of IRES (e.g., among cli- mates or types of geology. We illustrate this within the French CZO and LTSER, including their diversity as socio-ecosystems, and detail human inter- actions with IRES. These networks are also specialized in the long-term obser- vations required to detect and measure ecosystem responses of IRES to climate and human forcings despite the delay and buffering effects within ecosystems.
The CZO and LTSER platforms also support development of innovative tech- niques and data analysis methods that can improve characterization of IRES, in particular for monitoring flow regimes, groundwater-surface water flow, or water biogeochemistry during rewetting. We provide scientific and methodo- logical perspectives for which this interdisciplinary approach and its associated infrastructure would provide relevant and original insights that would help fill knowledge gaps about IRES.
