- Plant domestication versus crop evolution: a conceptual framework for cereals and grain legumes. Only traits showing clear dimorphism between wild and cultivated taxa are really part of Domestication Syndrome. If there’s a continuum, it happened afterwards.
- Reconfiguring Agrobiodiversity in the Amazon Estuary: Market Integration, the Açaí Trade and Smallholders’ Management Practices in Amapá, Brazil. Açaí driving out other crops. Sometimes those underutilized crops should stay that way? Maybe not, as at the same time, homegardens are diversifying.
- Mining germplasm banks for photosynthetic improvement — wheat, rice, potato, legumes and maize. You need maps.
- Do faba bean (Vicia faba L.) accessions from environments with contrasting seasonal moisture availabilities differ in stomatal characteristics and related traits? Yes. Those maps again.
- Can Polish wheat (Triticum polonicum L.) be an interesting gene source for breeding wheat cultivars with increased resistance to Fusarium head blight? What do you think?
- Genetic diversity and classification of Oryza sativa with emphasis on Chinese rice germplasm. Six major groups, not five. We shall see.
- Genetic dissection of drought tolerance in chickpea (Cicer arietinum L.). It could all (or mostly) be down to one genomic region.
- Historical changes in the process of agricultural development in Cuba. I suppose one could say that, in a way, it’s back to the future.
- Developing more productive African agroforestry systems and improving food and nutritional security through tree domestication. Participation, post-production, private-public partnership.
- Market-based mechanisms for biodiversity conservation: a review of existing schemes and an outline for a global mechanism. Need to have a standard unit of measurement, and a mechanism for ensuring a long-term perspective. Can agricultural biodiversity learn from this?
Joining up the dots
Four blog posts from the CGIAR today. Related, as you’ll see, but not connected. Leaving us to join up the dots. Because that’s what we do. You’re welcome, CGIAR.
- From ICRAF, to kick things off, a piece summarizing the editorial accompanying the special edition of the journal Current Opinion in Environmental Sustainability. The message is that the interaction between people and trees, in forests or agroforestry, is complicated and its study requires systemic approaches.
- Funnily enough, over at CIFOR there’s an example of just such a study, looking at the relationship between forest cover and children’s nutrition. Which encountered just the sort of problem alluded to above: “We were unable to figure out from our data whether people living near forests are collecting more nutritious foods from the forest, if they are cultivating them on farms and in agro-forests, or a combination.” Awkward.
- And so we come to the Landscapes for People, Food and Nature Initiative’s post on the use of mapping to look at ecosystem services. Including presumably the sort of ecosystem services the previous two pieces looked at.
- Funny though how it doesn’t mention CIAT’s work on using GIS to look at the level of forest protection actually enjoyed by Colombian forests in that country’s protected are system.
LATER: Ok, ok, the third one is not really from the CGIAR. Read the comment for more.
Brainfood: Tanzanian maize, ITK, Genebank value, Congolese bananas, Amaranth domestication, Ethiopian coffees, Dacryodes diversity, Apple diversity, Breeding pulses, Commons, Beet genetic structure, Restoring landscapes, Indian agrobiodiversity
- Modern maize varieties going local in the semi-arid zone in Tanzania. OPVs from the 80s are creolizing still, and that’s a good thing.
- Traditional Knowledge Systems, International Law and National Challenges: Marginalization or Emancipation? Well, it looks like it’s the former, but should be the latter. ‘Twas ever thus.
- Valuing insurance services emerging from a gene bank: The case of the Greek Gene Bank. Benefits are greater than costs. Phew.
- Banana genotype composition along the Uganda-Democratic Republic of Congo border: a gene pool mix for plantain and highland bananas. You can still find new stuff. And get funding to look for it, clearly.
- Relationships between the Weedy Amaranthus hybridus (Amaranthaceae) and the Grain Amaranths. Multiple domestications? And why not.
- Genetic Diversity Analysis of Some Ethiopian Specialty Coffee (Coffea arabica L.) Germplasm Accessions Based on Morphological Traits. As ever, useful variation was found. We await its arrival in our morning cup.
- Genetic diversity of Dacryodes buettneri (Engl.) H.J. Lam (Burseraceae), a timber tree in Central Africa. There is some. It could be important, yada yada.
- Malus sieversii: A Diverse Central Asian Apple Species in the USDA-ARS National Plant Germplasm System. The infra-specific taxa may not hold up.
- Exploiting Genomic Resources for Efficient Conservation and Use of Chickpea, Groundnut, and Pigeonpea Collections for Crop Improvement. It’s so close, these guys can taste it. When will we?
- Is genetic information a commons? Maybe it should be.
- Genetic structure and gene flow in Beta vulgaris subspecies maritima along the Atlantic coast of France. The latitudinal cline that wasn’t.
- Restoration of degraded agricultural terraces: Rebuilding landscape structure and process. Restoration is not enough, you need continuous management thereafter. Probably applies to the agricultural biodiversity too, when you think about it.
- Agro-biodiversity in rice–wheat-based agroecosystems of eastern Uttar Pradesh, India: implications for conservation and sustainable management. Resource-poor farmers are better at agrobiodiversity conservation than rich ones. ‘Twas ever thus.
Nibbles: Rice show, Central Asian forests, Research archives, Opium, Data stuff, Indian seeds, Ag expansion
- Rice symposium wows Hong Kong.
- Fruits and nuts of Kyrgyzstan.
- Rothamstead’s archives look totally cool.
- One does wonder whether Afghanistan could learn something from Colorado.
- When did continued collaboration become news, CIAT?
- Cherokee continue to save seeds.
- Agricultural expansion a continuing a bad thing for nature.
Brainfood: Diversity in restoration, Niche model validation, Dutch diets, Markets in conservation, Genomics for stress, Protected agroecosystems, Cocksfoot diversity, Tree breeding, Organic in India, Coconut origins, Dope diversity
- Application of genetic diversity–ecosystem function research to ecological restoration. Cultivars vs local populations vs genetic diversity approaches in restoration reviewed. More research needed, natch, but genetic diversity should not be dismissed out of hand in a bid for rapid establishment or long-term persistence, as it may well be best for ecosystem functioning.
- Application of consensus theory to formalize expert evaluations of plant species distribution models. Given arm-twisting, experts like models.
- Exploring dietary guidelines based on ecological and nutritional values: A comparison of six dietary patterns. The Dutch should eat less meat. No word on beer.
- Market-based mechanisms for biodiversity conservation: a review of existing schemes and an outline for a global mechanism. You can’t monetize what you can’t measure.
- Genomic resources for breeding crops with enhanced abiotic stress tolerance. You still need the phenotyping.
- Perceptual distinctiveness in Native American maize (Zea mays L.) landraces has practical implications. Kernel colour diversity is a marker for other, more interesting, kinds of diversity.
- Can agro-ecosystems efficiently complement protected area networks? Yes, but only in combination with expansion of protected natural habitats. For birds in Israel, that is.
- Indicators for genetic and phenotypic diversity of Dactylis glomerata in Swiss permanent grassland. Management alters both genotype and phenotype.
- A ‘Reality Check’ in the Management of Tree Breeding Programmes. Have come far, but still a ways to go, in particular with regard to the balance between DNA-based vs conventional breeding and genetic gain vs genetic preservation.
- Yield and Economic Performance of Organic and Conventional Cotton-Based Farming Systems — Results from a Field Trial in India. Organic soybean may be a viable long-term option. Cotton and wheat, jury still out. But early days yet, these rotation trials take a long time to get going.
- Long-distance dispersal of the coconut palm by migration within the coral atoll ecosystem. Hugh Harries, one of the authors, in a recent email to us: “Recent reviews have blown dust from old reports of pre-Colombian coconuts in Panama and demonstrated how the rate of germination distinguishes the naturally selected wild coconut from the domestically selected sort. This review formulates a hypothesis which could identify a previously unconsidered route along which the primordial coconut might travel between the South American and Indian tectonic plates without being indigenous on either.” That is, atoll-hopping.
- Differentiation between fiber and drug types of hemp (Cannabis sativa L.) from a collection of wild and domesticated accessions. Must have been fun doing the evaluation.
