Social-ecological enabling conditions for payments for ecosystem services

The concept of “enabling conditions” centers on conditions that facilitate approaches to addressing social and ecological challenges. Although multiple fields have independently addressed the concept of enabling conditions, the literature lacks a shared understanding or integration of concepts. We propose a more synthesized understanding of enabling conditions beyond disciplinary boundaries by focusing on the enabling conditions that influence the implementation of a range of environmental policies termed payments for ecosystem services (PES). Through an analysis of key literature from different disciplinary perspectives, we examined how researchers and practitioners refer to and identify enabling conditions within the context of PES. Through our synthesis, we identified 24 distinct enabling conditions organized within 4 broad themes: biophysical, economic, governance, and social-cultural conditions. We found that the literature coalesces around certain enabling conditions, such as strong ecosystem science and existing institutions, regardless of disciplinary background or journal audience. We also observed key differences in how authors perceive the direction of influence for property type, program objectives, and number of actors. Additionally, we noted an emphasis on the importance of the contextual nature of many enabling conditions that may cause certain conditions to have a disproportionate impact on successful implementation in some circumstances. Unraveling the relative importance of specific enabling conditions in diverse contexts remains a research frontier. Ultimately, no single disciplinary perspective is likely to provide all necessary insights for PES creation, and given the intertwined nature of enabling conditions, practitioners need to consider insights from multiple dimensions. Our work suggests opportunities to better connect diverse conversations through integration of concepts, a common vocabulary, and a synthetic framework.

Ecosystem Services Valuation as an Opportunity for Inquiry Learning

ABSTRACT Teaching ecosystem services provides an ideal opportunity to use inquiry-based learning to help students make connections between ecological, geological, and social systems. The idea of ecosystem services, or the benefits nature provides to society, has emerged as a key concept in a host of environmental fields and is just beginning to gain attention within the geosciences. Although the concept has the potential to positively affect policy decisions by quantifying the economic value of ecosystem services, it has been criticized for commodifying nature and having limited engagement with geoscience perspectives. To teach ecosystem services to the next generation of geoscientists, we developed two variations of an inquiry-based learning exercise in which students used the ecosystem services approach to assign a monetary value to eight different ecosystem services generated by four ecosystems. One version of the exercise had students make these valuations in the field, whereas one was completed solely in the classroom. In both cases, the students scored significantly better on a postexercise assessment, demonstrated a deeper understanding of the ecosystem services approach, and reported that the exercise was preferable to a traditional lecture. Our data and observations also suggest that this exercise offers a great deal of flexibility and can be used in many learning environments. Geoscientists should be especially interested in integrating the concept of ecosystem services into their courses so that the next generation of geoscientists is well positioned to contribute to the interdisciplinary field of ecosystem services.
