As the blog enters its 7th year, it is time for the annual review of how well it is meeting its aims of:
- sharing concepts, methods and other tools for tackling complex societal and environmental problems and acting as a repository of those tools
- being a global vehicle for exchange, discussion and network building to strengthen use of those tools.
All the trends are in the right direction, providing impetus to keep expanding the base of contributors and coverage of key topics. If you have developed a relevant tool or use an existing tool in a new way, I would love to hear from you. Comments on blog posts are always valuable. And, of course, feedback and suggestions are welcome.
This is the last blog post for 2021.
