Now published: Disentangling the causal mechanisms that link participation and collaboration to environmental outcomes

By Jens Newig

Many agree that participation and collaboration is relevant, if not indispensable, for environmentally sustainable governance outcomes. Others maintain that public government is best equipped to effectively address environmental problems. In our new paper from the ‘EDGE’ project we try to move the debate forward by looking precisely at the causal mechanisms through which participatory and collaborative forms of governance may improve (or deteriorate) environmental outcomes of public decision-making processes.

The paper is rather analytical in that we disentangle:

  1. different dimensions of participation: Who participates? What decision-making power is delegated to participants? How do participants communicate and interact?
  2. different dimensions of outcomes: Outputs on paper (plans, agreements, policies, etc.) versus the support of outputs and their actual implementation
  3. the different mechanisms through which participation and collaboration likely work towards (or against) environmental outcomes,
  4. different contextual factors such as the capacity of stakeholders, problem complexity or the degree of conflict (we call these ‘conditioning variables’).

This analytical ‘disentangling’, we believe, helps us to identify trade-offs: For example, a collaborative process involving local resource users may lead to a conservation plan with less environmental aspiration as envisaged by a nature-protection agency (because local users do not strictly favour conservation). But at the same time, this plan may be more accepted by local communities and better implementable.


This figure shows an overview of the causal mechanisms we identified, organised in five thematic clusters. Plus signs (+) denote reinforcing relationships, minus signs (–) denote weakening relationships. For example, the top left arrow combines mechanisms M I.1a (positive influence of “opening up” on representation of environmental concerns) and M I.1b (negative influence).

We hope that this framework of causal mechanisms will futher stimulate debate on the functions of participation, and ultimately be useful for guiding empirical research. To this end, we will draw on this framework to organise our empirical findings from the EDGE case survey meta analysis.
