Motivational crowding effects in payments for ecosystem services: Exploring the role of instrumental and relational values

[摘要] 1. Nature is perceived and valued in many different ways. Often, the types of values that are the most important to people depend on how they cognitively framedesirable human–nature relations. For instance, the value of nature can be seenthrough a utilitarian lens, for example, as providing ecosystem services for humans.Alternatively, it can also be considered valuable for non-instrumental reasons, forexample, for its sacred or spiritual significance.2. In this paper, we use a framed field experiment to test how people belonging to three distinct communities in Colombia (Indigenous, Afro-Colombian andCampesino) respond to different ways of framing payments for ecosystem services (PES) schemes, so as to assess potential motivational crowding effects ofpro-social/intrinsic motivations for forest conservation.3. The experimental results indicate that crowding-in of intrinsic motivations for forest conservation occurred in participants from the Indigenous community whenthe PES scheme was framed in a way that highlighted the relational values of theforest.4. By contrast, motivational crowding-in took place for participants in the framedfield experiment from the Campesino community when the PES scheme wasintroduced in a way that highlighted instrumental values instead.5. Participants from the Afro-Colombian community did not show the evidence ofmotivational crowding under either framing.
