Back in Baku
I’ve been travelling so I missed the announcement a couple of days ago on their blog that our friends at CCAFS ((That’s the CGIAR’s research programme on Climate Change, Agriculture & Food Security, do keep up.)) have a new all-singing, all-dancing platform called the Adaptation and Mitigation Knowledge Network. ((No, don’t ask me how it relates to this.)) Which is annoying because the issue of changes in the suitability of the climate for potato cultivation came up in the discussions at the meeting I’m attending here in Baku. And I would quite happily have stolen something else from CCAFS for my presentation. ((Not that it would have been easy. You can’t really share the AMKN maps.)) The conference is called “Diversity, characterization and utilization of plant genetic resources for enhanced resilience to climate change” and it was hosted by the Azerbaijan Genetic Resources Institute with support from a number of CGIAR Centres active in the region and FAO, which provided funding for the project of which the meeting is one of the activities.
There were researchers from pretty much all of the countries of the Central Asia and Caucasus (CAC) region, plus Turkey, Iran, Ukraine and Russia to boot. Many of the presentations brought home to me — and not for the first time — what a tremendously rich part of the world this is for agricultural biodiversity: wild asparagus with stems five meters long; grape varieties sporting bunches almost as long as your arm; strange interspecific wheat hybrids with branched spikes; medicinal plants for every ailment you can think of; wheat landraces phenomenally high in zinc and iron. And that’s just the lunch. Fortunately, the place is also rich in talented researchers busy studying their agrobiodiversity, conserving it, and using it for health, nutrition and food security.
Sure, they have problems. Where do they not? But there seems to be a real commitment to getting the job done, enthusiasm even. I was particularly struck by the relatively close linkages between genebanks and breeding programmes in many of the CAC countries. That you certainly don’t see everywhere. I wonder if it’s a legacy of the VIR system. They could do with more collaboration, coordination and sharing of responsibilities at the regional level, not to mention better integration with the rest of the world. But maybe this meeting will help. Anyway, all the presentations, abstracts and final recommendations will be online soon. I’ll post something when they’re up and you can make up your own minds.
To corridor or not to corridor
The fact that distribution change occurs predominantly through spatially restricted, local population processes suggests that the development of ecological networks may be an effective conservation strategy for plant species in the UK (Lawton et al. 2010). An ecological network comprises sites which collectively contain the diversity and area of habitat needed to support species and which have ecological connections between them. The UK is largely made up of semi-natural habitats shaped by human land use, and so consequently, much of the UK’s wildlife is restricted to small fragmented areas of high habitat quality. These can rarely be restored to large unbroken areas of natural habitat. However, making connections between them through wildlife corridors and smaller ‘stepping stone’ sites is a much more feasible option, which would improve species ability to track environmental change through short-range colonisation (Hilty, Lidicker & Merenlender 2006).
…constraints imposed by climatic variability, limited dispersal and low persistence may mean that even habitat corridors through high-quality habitat may not in themselves make range shifts possible. Additionally, corridors for species that show high uncertainty between climate paths under different GCMs are less likely to be effective.
These are from papers in Journal of Ecology and Ecology Letters published within days of each other, though admittedly one dealing with plant species in Britain the other with amphibians in the USA. So what’s a poor boy to do? Stop thinking there’s one solution for everything, I suppose. And get everything into ex situ just in case.

- Australians justify their investment in IRRI. Now that’s what I call impact!
- Peruvian cuisine takes over the world. But, as Eve points out elsewhere, “We have a thousand kinds of potatoes in Peru, thousands” is not hyperbole.
- Jess scoops the world with a nutrition strategy for the masses.
- Indians need sorghum and millets to keep healthy.
- Ethnobiology: The Book.
- Talking about street food. Hold the mayo.
- Not all pigs are cloven-hoofed. A tetrapod zoologist explains syndactyly.
- Polyculture; is it all Pollyanna? Science will answer.
- A flavour map of British cheeses. You know you need it.
- Foraging for pawpaws. Not those pawpaws.
- Bird areas apps. CWRs next?
Brainfood: Breeding resistance, Pastures, Wheats, Dates, Conservation, Habitats, Old olives, Spinach selection, Maize breeding
- Cytological and Molecular Characterization of Homoeologous Group-1 Chromosomes in Hybrid Derivatives of a Durum Disomic Alien Addition Line. Getting tolerance to Fusarium head blight into durum wheat ain’t easy.
- Sustainable, low-input, warm-season, grass–legume grassland mixtures: mission (nearly) impossible? Apparently really difficult to find native North America legume forage species tolerant of both freezing and high temperatures, but people are looking. Gotta wonder if it’s a problem elsewhere too. Ethiopian highlands?
- Diversity of different farmer and modern wheat varieties cultivated in contrasting organic farming conditions in western Europe and implications for European seed and variety legislation. Strong selection for uniformity (for regulation) is not reflected in uniformity assessed on farm. And farmer varieties were good outside their region of origin.
- Glycaemic index of three Indian rice varieties. All three the same, high, GI. So, “There is an urgent need to study the GI of other commonly consumed rice varieties and to develop rice of a lower GI value”. Er, right.
- Glycemic indices of five varieties of dates in healthy and diabetic subjects. All five the same, low, GI and no difference in diabetics.
- Agricultural expansion and the fate of global conservation priorities. Conservation needs to think about agriculture.
- Which habitats of European importance depend on agricultural practices? 63 of them, mainly through grazing and mowing.
- Centennial olive trees as a reservoir of genetic diversity. Only about 10% of old trees matched current cultivars.
- Phenotypic Changes in Different Spinach Varieties Grown and Selected under Organic Conditions. There were phenotypic changes after just three seasons of selection, in one case resulting in a “new” variety.
- Open-Pollinated vs. Hybrid Maize Cultivars. Hybrids are not the only way to improve maize productivity, apparently.
- Plant breeding for harmony between agriculture and the environment. “Plant breeding can be a powerful tool to bring “harmony” between agriculture and the environment, but partnerships between plant breeders, ecologists, urban planners, and policy makers are needed to make this a reality.” I was just going to ask, why can’t we all just get along.
