Rivers, water, nature, people. Sometimes other stuff.
(14/n) Local action to restore of #rivers, #lakes & #wetlands is critically important for lots of reasons.
But unless we start to redirect the underlying policy & business drivers of ecosystem degradation, we won't bend the curve of global freshwater biodiversity loss.

(12/n) That community is often insular & narrowly focused on biophysical sciences (ecology, hydrology, geomorphology).
Freshwater scientists should engage far more with social sciences to generate understanding of policy-business-ecosystem links & to map future pathways.

(10/n) If conservationists are to influence these drivers, they need to make the case for bending the curve in terms that chime with the priorities of policymakers & business leaders in these sectors.
Our paper describes those priorities, and potential implications for freshwater biodiversity.

(9/n) We drew on our collective experience in research, policy & conservation practice to suggest key policy/business sectors for freshwater biodiversity.
We particularly focused on #water resource management, #agriculture & #food, #energy, & inland #fisheries.

(8/8) Kudos to lead author Lauren Kuehne (some of whose slides I've used in this🧵), instigator Chris Dickens, & co-contributors (and big brains) @oldenfish.bsky.social, Bernhard Lehner @mcgillgeography.bsky.social, Gordon O'Brien & Nishadi Eriyagama .👏👏👏👏👏👏

(6/8) We identified data & technical priorities, and pointed to opportunities to advance global river health monitoring such that an adequate monitoring framework could be in place and implemented by 2030, with the potential for substantial enhancement by 2050.

(5/8) Using these insights, we developed a comprehensive set of scalable indicators that can support “top-down” global surveillance of #rivers & also facilitate standardised “bottom-up” local monitoring efforts.
These included Biological, Water Quality, Physical Habitat & Hydrological indicators.

(4/8) We also reviewed emerging approaches such as remote sensing, citizen science, improved modelling & AI.
These present huge opportunities to improve policy-relevant river health monitoring at multiple scales... if they are well-co-ordinated.

(3/8) But in recent years, development of large (eg. national) scale river health monitoring frameworks has accelerated.
We distilled lessons from frameworks in 🇳🇿, 🇺🇸, 🇿🇦, 🇨🇳, the 🇪🇺 & 🇦🇺, plus specific initiatives such as the Freshwater Health Index.

(2/8) Freshwater systems like #rivers are vital for people & nature but have been under-represented in agreements like the SDGs & UN Convention on Biological Diversity.
One reason for this is the lack of oven-ready, global-scale indicators of river health. Govts won't set targets they can't track.

Here's another version of the same thing, from this book on #drought risk management: unesdoc.unesco.org/ark:/48223/p... (and originally from the Nebraska Drought Monitoring Centre)

To which I'd add Simon Winchester's "River at the Centre of the World" - a fascinating account of the central role of the Yangtze River in Chinese history. Written just as China was opening up, and as the Three Gorges Dam was moving from drawing board to massive concrete reality.

I have a new favourite scientific name for a species: Umma gumma, aka the Robust Sparklewing*.
A species of #dragonfly found and named after the 1969 album by #PinkFloyd.
*The common name is pretty good too.
