Vanuatu field collections survive cyclone

A smidgen of good news from the Pacific island country of Vanuatu, recently hit so cruelly by Cyclone Pam. This just in ¹ from Roger Malapa, who’s in charge of the various field genebanks at the Vanuatu Agricultural Research and Technical Centre (VARTC) on the beautiful island of Santo, which was apparently less badly affected than others.

Minor damage to the banana collection but overall, everything is fine at VARTC and Santo. Yes there is enough material in the multiplication plots, mainly the root crops. I have just selected an early maturing variety on February: two-month harvest. We are harvesting our cassava now so cuttings can be prepared.

SPC’s Centre for Pacific Crops and Trees (CePaCT) does hold duplicates of some of these collections in vitro. But you can never have enough safety duplication in the Pacific.

Here’s what a bit of the root and tuber crop collection at VARTC looked like a few years ago when I last visited.

A book worth waiting for

With our own hands

An old friend, Frederik van Oudenhoven, and his friend and colleague Jamila Haider, are deep in the proofs of what looks to be a wonderful book. With Our Own Hands “tells, for the first time, the cultural and agricultural history of the Afghan and Tajik Pamirs, one of the world’s least known and most isolated civilisations”. Should be a great read, with stunning photographs to accompany the local recipes, essays, stories and poetry. Better yet, generous donors are allowing 1800 copies to travel back to the Pamirs to be given to communities, schools, cooks and libraries.

If you’re interested, you should pre-order. Details here.

Does Plant Species Richness Guarantee the Resilience of Local Medical Systems? A Perspective from Utilitarian Redundancy. It depends on how knowledge is distributed.
COLD1 Confers Chilling Tolerance in Rice. From a wild relative.
Searching for the Oldest Baobab of Madagascar: Radiocarbon Investigation of Large Adansonia rubrostipa Trees. 1,600 years seems to be the record.
Genetic resources of cultivated plants as the basis for Russia’s food and environmental security. VIR needs Roubles 425 million a year ($14.3 million).
Using archaeogenomic and computational approaches to unravel the history of local adaptation in crops. Models say that adaptation to higher latitudes was rapid, simple (few genes) and unstable.
Combining conservative and variable markers to infer the evolutionary history of Prunus subgen. Amygdalus s.l. under domestication. Almonds and peaches were domesticated on either side of the Central Asian Massif from different sections of the genus that had been there for 5 million years.
Conservation implications of the mating system of the Pampa Hermosa landrace of peach palm analyzed with microsatellite markers. Bactris effective population size in genebanks is too small.
Global effects of land use on local terrestrial biodiversity. Within-sample total terrestrial species diversity down by 13.6% globally. About the same for crop wild relatives?
Exploiting genetic diversity from landraces in wheat breeding for adaptation to climate change. It would be a good idea.
Household Agrobiodiversity Management on Amazonian Dark Earths, Oxisols, and Floodplain Soils on the Lower Madeira River, Brazil. Age of household head, size of household and area of land under cultivation predict amount of agricultural biodiversity managed.

Monitoring plant diseases

I think we may have blogged about ProMED before, but I don’t feel at all guilty about another shout-out. I have no idea to what extent the whole thing is automated, but if there’s anything in the press about a disease — of plants, livestock or humans — it gets a little write up on the website, and a dot on the map. And you can sign up for email alerts or subscribe to an RSS feed, or indeed to their Twitter feed or Facebook page if that’s your vice. I sometimes dream of doing something similar for all kinds of threats to agrobiodiversity.

And while we’re on the subject, just a reminder that there’s a new new app for Pacific pests and pathogens, courtesy of those nice people at Pestnet.

Nibbles: Local earthworm, Public-private, Cassava double, Food prices, Amazonian rubber, Mongolian ag, Pacific roots, Potato CWR, Ugandan plantain, Galician brassicas, Contesting agronomy, Silver bullet

Lamb ham: an easter tradition we can all get behind.
Indian researchers market a new earthworm. Not to bring you down or anything.
PPP are the new black. It says here.
Cassava gets Big Data treatment. That’s kinda biotechnology too. But then you have to commercialize the stuff, right?
“Food price shocks are both a determinant and effect of conflict.”
Recognizing the “rubber soldiers”.
Chinese experts tell Mongolians how to be more resilient to climate change. I hope it works out for them.
New potato and sweet potato varieties for the Pacific come to CePaCT.
Any of those potato varieties benefit from wild relatives?
New plantain variety for Uganda.
Galician genebank gets old brassicas. National genebank unavailable for comment. Actually, national genebank unavailable.
“We can see the blinkered promotion and systematic ‘bigging-up’ of individual agricultural technologies, and their real or imagined impacts, as a direct result of the uncritical acceptance of the language of ‘impact at scale’.”
