PGR training needs identified

There’s an open access Crop Science Special Issue out under the title: Connecting Agriculture, Public Gardens and Science. Well worth having a look at. There’s great stuff on crop wild relatives, plant awareness, chefs, and trans-situ conservation, just to give you a flavour. There’s also a summary of the symposium that gave rise to the special issue. Our friend Colin Khoury was closely involved.

I’ll just highlight here the paper by Gayle Volk and others on training needs in plant genetic resources conservation. ¹ The authors sent out a survey and analyzed the feedback from 425 respondents by type of institution: academia, NPGS, CGIAR, national genebanks, NGOs and the private sector. There were, fortunately, some topics which a majority across all institutions considered high priority areas for training:

accessing information
crop wild relatives
genotyping
phenotyping
intellectual property and regulatory issues

But there were also some differences.

The respondents from academia were also interested … in prebreeding, which is not surprising because many of these respondents were plant breeders. Respondents from the private sector were also interested … in requests/distributions and prebreeding, and respondents from NGOs were also interested … in collection gap analyses, explorations, germplasm preservation, intellectual property, and regulations. The genebank respondents (NPGS, CGIAR, non-NPGS government) considered germplasm preservation, intellectual property, and general concepts in plant genetic diversity as priority topics. These differences among the institutional types are not surprising due to their different missions.

This all came out of an initiative from the NPGS that started back in early 2018. Training materials of various types are being developed. Will keep you posted.

Nibbles: International genebanks, Ahmed Amri, Genebank management, Nutrition stories, Spice nomenclature, Breeding against waste, Cuneiform tablets, Breadfruit, Ag risk, Giant pineapple, Chiles in Mexico, Solanum jamesii, Seed Week, Kenyan community seedbank, Lost apples

The CGIAR genebanks in the limelight.
My friend Ahmed Amri is a big reason for the success of the above.
The dual role of genebank managers like Ahmed.
Feel-good nutrition stories needed.
Rosemary gets a name change. Not many people hurt.

Hey, it’s Seed Week 2019 in the UK and Ireland!
Something similar in Kenya too, thanks to Bioversity and CCAFS.

A bit more on what happened at GB8

I did suggest a couple of days ago that I’d have more to say about the Eighth Session of the Governing Body of the International Treaty on Plant Genetic Resources for Food and Agriculture. And here it is, over at the work blog.

If you think I got anything wrong, or missed anything out, or you want further details or clarifications, you can leave comments here if you like, and I’ll try to reply, or get others to do so if I can’t.

Staving off the apocalypse

Multiplying the budget of CGIAR, the world’s largest global agricultural innovation network, would be a good start. And, in a time of great disruptions, we ought to prioritize Sustainable Development Goal 2.4, implementing resilient agricultural practices, with a greater focus on smallholder farmers in developing countries.

That’s from a post by Asaf Tzachor, research associate at the cheerfully named Centre for the Study of Existential Risk at the University of Cambridge, cheerfully entitled Down the Hunger Spiral: Pathways to the Disintegration of the Global Food System. Hard to argue with, except for maybe that SDG 2.5 may be even more important than 2.4

And it was soon backed up by a piece in The Economist which had agricultural R&D in the top 3 value-for-money development interventions for Africa, according to the Copenhagen Consensus.

So what’s the hold-up?
