Jonathan Tonkin @jdtonkin.bsky.social · 05/10/2026“Rather than treating rivers as systems that must be tightly controlled or returned to a fixed historical state, the research highlights the need to anticipate change, manage adaptively, and work with natural river processes to improve both flood resilience and ecosystem health.” 041

Jonathan Tonkin @jdtonkin.bsky.social · 22/09/2026The 7 forms of resilience (from ecology, applied to parenting): 1. Spatial diversity — more than one place to belong 2. Network diversity — more than one person to rely on 3. Resource diversity — more than one way to meet basic needs 4. Functional redundancy — more than one way to solve a problem 121

Jonathan Tonkin @jdtonkin.bsky.social · 16/09/2026Great thread! I think the Fry example highlights the importance of reading widely to generate or ‘spot’ good ideas. To me, very little is truly new. Most is repackaging of old ideas in new ways — evolution. Novel ideas are often just taking two distinct things and bringing them together. 120
