- Nutrition and culture in professional football: A mixed method approach. Footballers need a more diverse diet. Well, kinda. I just wanted to get this paper in here because wouldn’t it be cool if we could get Lionel Messi to talk about agrobiodiversity-rich diets?
- Diversity analysis using ISSR markers for resistance to shoot pests in sorghum. There may be a diversity of resistance mechanisms.
- Domestication of Alpine blue-sow-thistle (Cicerbita alpina (L.) Wallr.): six year trial results. I know. Why would you want to, right? Takes all sorts to make a diverse diet, I guess. Maybe we can get Lionel Messi to eat it?
- Improving representativeness of genebank collections through species distribution models, gap analysis and ecogeographical maps. Fancy GIS-based prioritization results in more, better germplasm collecting. Nice to have the data.
- Evolutionary Plant Breeding in Cereals—Into a New Era. Martin Wolfe and colleagues lay it on the line; why it is a good idea, and what the obstacles are.
- Genetic interactions influence host preference and performance in a plant-insect system. Aphids and barleys have genetic preferences for one another.
- Pasture area and landscape heterogeneity are key determinants of bird diversity in intensively managed farmland. As in the northern hemisphere, so too in Argentina.
- Tree diversity and conservation value of Ngovayang’s lowland forests, Cameroon. Both high, and I’m betting some economically important trees are among them.

From little acorns (and other tree seeds) mighty oaks (and other trees) grow
Astute followers of the Commenters to our blog will know that James Nguma, an enterprising Kenyan, is looking for scientific names for some trees his group is interested in. 1 James’ comment comes at an opportune moment. Scidev.net summarizes an article by researchers at the World Agroforestry Centre to the effect that African farmers deserve certified tree seed. 2 Why? “To help farmers know what trees they are planting so that they can make informed decisions”, according to the lead researcher. Also today, Eldis Agriculture drew attention to a 2007 report, also from the World Agroforestry Centre, that presented results from a survey of tree-nursery farmers in Malawi. And the point of this post is to ask what the people who wish to plant trees, like James Nguma and Luigi’s MIL, actually want?
My suspicion, although I have carried out neither the desk studies nor the on-site interviews to confirm this, is that they want sturdy saplings of locally sourced provenance that will grow away well and that are adapted to local conditions. Cheaply. How will certified seed serve their needs? And how can nursery owners be helped to supply them with what they need?
A third paper — Innovation in input supply systems in smallholder agroforestry: seed sources, supply chains and support systems — actually supplies answers. But it also sounds a cautionary note:
Lessons from the evolution of smallholder crop seed delivery systems can be applied to tree germplasm supply and indicate that a commercial, decentralised model holds most promise for sustainability. However, current emphasis in agroforestry on government and NGO models of delivery hinder the development of this approach.
The paper is Open Access, so you can read the whole thing and see whether you agree that neither of the two “centralized” models, Government and NGO, is actually the best way to get good quality tree seedlings into the hands of farmers who want to plant them.

World Food Day deconstructed
Lately we’ve done a fair bit of pointing you to other blog posts that have something worthwhile to say on topics of interest here. You may call this laziness. We call it content curation. And in that spirit I offer you one person’s take on World Food Day, which unfolded yesterday here in Rome and which continues all week with a diversity of talking shops. I’m not going to comment on the commentator, except raise a question about his description of FAO as
[T]he single entity that we rely on the most to inform us about the state of cultivators, what they’re growing in our world, and who isn’t getting enough of those crops as food.
Is it? Really? I’m too deep in to know whether this is a genuine reflection of how people see FAO, and would welcome enlightenment.
