Co-production of nature’s contributions to people in dry rivers: a case study in Murcia, Spain

Abstract

ABSTRACT Dry rivers are non-perennial rivers with no surface water in their channels except after heavy rainfall or snowmelt. The lack of water flow is often associated with a low provision of Nature’s Contributions to People (NCP) and a poor quality of life. However, recent review studies have found evidence of human communities thriving in dry rivers through the co-production of multiple NCP, although no case studies have yet confirmed this evidence. We assessed the capacity of dry rivers and their associated social systems to provide NCP. We selected three dry rivers with high natural, cultural and landscape values in the most arid part of Murcia (Spain). We interviewed 37 representatives of the most influential social groups in the study area to explore the NCP of dry rivers, their synergies and trade-offs. Four material, three non-material and eight regulating NCP were identified, as well as one unique NCP: access to villages and fields through dry riverbeds. Fifty-two synergies were identified, especially between material and non-material NCP, and eight trade-offs. This wide range of NCP and synergies is a consequence of the co-production processes between dry rivers and the social system. NCP co-production seems to be underpinned by the indigenous and local knowledge acquired by the social system over generations about the management of floodwaters, biodiversity and geodiversity. Incorporating this knowledge into research and governance can help raise awareness of the NCP provided by dry rivers and help develop strategies for mitigating and adapting to global change.
