Indicators may be presented in many ways

A few examples

“Fishing down the foodweb (Pauly)”

We also

log, plough, burn, convert, burn, pollute

and hunt

down ecosystems

Linking biodiversity loss with economic sectors

Change in natural ecosystem extent

Universally applicable 2.

Easy to understand

Fair comparison within & between countries4.

Gradually implementable

(cheap -> exp)

Linkable with economic sectors6.

Coherent with CBD and global assessments

Establishing baselines 8.

Monitoring requires expertise & budget (methods available)
