Ann Tutwiler, DG of Bioversity, on why we have to solve a quadratic equation of food security now. But is it 7,000 edible plant species, or 12,000? h/t Nancy Castaldo
Go to page 9 for a cool infographic on nutrition which kinda illustrates that. But really, what a palaver to find it. Which actually I did via Twitter.
Quadratic? More like non-linear para-differential equations. Or one of those weird things out of chaos theory.
You can bet ICRAF think one solution to that equation involves the domestication of fruit trees.
Is Golden Rice another solution? There’s a debate later tonight that might help you decide.
And while we’re dealing with gene jockeys, apparently RNAi is the Next Big Thing.
Community, ecosystems, poverty reduction; urban agriculture can do it all. And Dyno Keating, DG of AVRDC, would probably agree.
And here’s a big PDF from the Centre for Indian Knowledge Systems to show you exactly how. Who needs equations?
Fed up with maths? Cacao, bean to bar, in photos.

A paean to diverse diets is just what we all need.
And another one, from the MIT Technology Review of all places.
Menawhile, there’s only one reference to dietary diversity in the World Bank’s investment framework for nutrition.
Maybe you have to quantify that diversity before you can save it? Now where have I heard that before?
Meanwhile, Europe reports on biodiversity-friendly farming practices. Does that include the biodiversity of the actual crops? Perhaps surprisingly, yes!
You want biodiversity-friendly farming practices? Talk to Indigenous people. The Committee on World Food Security (CFS) has launched an e-consultation on “Preserving, strengthening and promoting Indigenous Peoples’ food and knowledge systems and traditional practices for sustainable food systems.”
There’s diversity in asparagus too.
Genebanks can help with those biodiversity-friendly practices, diverse diets and rops and Indigenous practices.
Even big international genebanks.
Even the Svalbard Global Seed Vault.
But some are in trouble.
Though others are coming back.
