Second, is creating or capitalising on a conducive environment for change. This means taking advantage of 'triggers', such as crisis situations, political regime change or water-related treaties, to push forward reform.

This can be achieved through coalition-building and long-term advocacy, in which researchers have a key role to play — the influence of climatologists in convincing the public of the need to combat climate change is just one example of how researchers can garner public support. Countering resistance also has a key role and for this, it is important to identify people who stand to benefit from the status quo.

The fourth stage is negotiating the content of reforms and building a 'change package' that outlines reformulated policies. The authors highlight that when crafting such a package it is important to take a step-by-step approach that focuses first on urgent reforms with high potential for immediate impacts.

The final stage is about monitoring and evaluating to ensure that new policies are implemented and making an impact. This requires setting clear responsibilities, gaining political and resource commitments, and ensuring grassroots participation.
