- Genetic diversity of Brassica oleracea var. capitata gene bank accessions assessed by AFLP. Czech genebank; subgroups reflected place of origin.
- Optimizing the cropping mix in North Darfur State, Sudan. A study of Umkdada district. “…the results of the model were different from the real practices of the farmers.” Oh dear. To improve the fit, schoolboys should work in the fields more. And crops should fetch more. The dismal science indeed.
- Climate-driven simulation of global crop sowing dates. Ok, this model works. You can predict sowing dates under rainfed conditions for various annual crops from climatic conditions. Not entirely sure why you would want to, though.
- Exploring some of the myths of land use change: Can rural to urban migration drive declines in biodiversity? Yes, counter-intuitively, at least in the forests of Mexico’s southwestern highlands. More from Conservation Magazine.
- Pollination services in the UK: How important are honeybees? Quite a bit, but maybe not as much as previously thought. It’s the wild bees, stupid!
- Genetic diversity and symbiotic effectiveness of rhizobia isolated from root nodules of Phaseolus vulgaris L. grown in soils of Iran. It is high, and it varies, respectively.
- Interspecific hybridization of fig (Ficus carica L.) and Ficus erecta Thunb., a source of Ceratocystis canker resistance. It’s a breakthrough!
- Exploring the diversity of urban and peri-urban agricultural systems in Sudano-Sahelian West Africa: An attempt towards a regional typology. There are 6 types. Not 5; not 7. On this one, the journey is more interesting than the destination.
- Variability of wild olives (Olea europaea subsp. europaea var. sylvestris) analyzed by agro-morphological traits and SSR markers. There’s a lot of variabzzzzzzzzzz…
- Hemp in ancient rope and fabric from the Christmas Cave in Israel: Talmudic background and DNA sequence identification. Mainly flax, but some hemp, from both Roman and Chalcolithic periods. But can you smoke it?
- Modelling the distribution of domestic ducks in Monsoon Asia. Low resolution data, plus fancy modelling, can be used to get pretty good high resolution predictions.
- Gene flow between wheat and wild relatives: empirical evidence from Aegilops geniculata, Ae. neglecta and Ae. triuncialis. It happens, a lot.
- Toward food system sustainability through school food system change: Think&EatGreen@School and the making of a community-university research alliance. Food citizenship?
- Simulation of winter wheat yield and its variability in different climates of Europe: A comparison of eight crop growth models. Big differences among models, so best thing to do is to use the mean of all of them.
- The potential of plant viruses to promote genotypic diversity via genotype × environment interactions. The negative effect of White Clover Mosaic Virus (WCMV) infection on performance differs from white clover genotype to genotypes, which means differential selection, which means negative frequency-dependent selection in host populations, which means diversity. Via.
- Amplifying the benefits of agroecology by using the right cultivars. Why should we summarize, when an author has already done so?
Keeping bees in Hong Kong
I can’t resist sharing this wonderful video about a guy I found, well, inspirational is the only way I can describe him. And believe me, I don’t often use that word, at least about people. Clicking on the photo will take you to Vimeo. Thanks, Grist.
Nibbles: Spatial data, poverty, Livestock diseases, Romania, Cultural diversity, Iraqi marshes, Citizen science , Biohappiness, Beer!
- The CGIAR spatial crowd get it together? Not holding my breath.
- So tell me about that biodiversity-poverty link. Well, more research is, ahem, needed. Wet, for want of a better word.
- All the different kinds of “spots” for livestock diseases. How did they cope with the poor data? And have the various hotspots and coldspots been considered in drawing up the new research priorities for livestock?
- UNDP stumps up $4 million to plan biodiversity management in Romania. Including agrobiodiversity? Not holding my breath.
- A socio-economic impact analysis of cultural diversity in cities does not consider agriculture at all. There’s a PhD there for someone.
- IUCN’s plans for the Iraqi marshes. Thesiger unavailable for comment.
- If it can be done with amphibians, why the hell can’t it be done with agricultural biodiversity?
- Biojoy swamps Bioversity as Biohappiness book is launched.
- Yeah but was there any of this? And if not, why not? Via NWFP-Digest-L.

- Stop Press: Britain’s orchards neglected. Prince Charles to be called in to help?
- Eating the wild, in San Francisco and San Diego.
- IFAD on what African farmers need: infrastructure, insurance, investment. Apparently.

George Orwell and Food Security
George Orwell’s diaries are being posted to the web day by day, and we’ve noted some of his concerns about food and its production before. Seventy years ago, he had this to say about the value of food in times of crisis:
Sowed while at Wallington 40 or 50 lb. of potatoes, which might give 200 or 600 lbs. according to the season, etc. It would be queer – I hope it won’t be so, but it quite well may – if when this autumn comes those potatoes seem a more important achievement than all the articles, broadcasts, etc. I shall have done this year.
That he was even thinking such thoughts is interesting. Three days later he was musing about the conflict between “useless” animals and people over limited resources:
There are said to be still 2,000 racehorses in England, each of which will be eating 10-15 lb. of grain a day. I.e. these brutes are devouring every day the equivalent of the bread ration of a division of troops.
What did happen to racehorses during the war?
