- Perennial fodder crops to the rescue.
- Cool bird flu maps. GIS to the rescue.
- Persistent malnutrition? We know how to fix it. That’s the tragedy. Meanwhile, let’s consult the e-atlas.
- Cassava and potato to the rescue.
- Orange+purple sweet potatoes to the rescue.
Spatial datasets in the limelight
Two papers describing interesting spatial datasets appeared in my feed reader today. One looks at global landuse change over the past 12,000 years. Here’s the historical course of cropland expansion; there’s a similar set of maps for pastures:
The other paper concentrates on Europe, mapping out the intensity and type of farming, the idea being that not all “cropland” is the same:
In both cases you should be able to get a bigger image by clicking on it. I guess if we’re ever going to be able to investigate the link between agrobiodiversity and livelihoods on a global scale, ((Or even just agrobiodiversity and human population density.)) as people are doing with biodiversity and ecosystem services with poverty, we’re going to have to start with such datasets, enriched with diversity, including genetic diversity, data (or proxies).
How to bring in that diversity data? There are some ideas out there. But there’s a long way to go before we have a global picture of the current spatial distribution of crop diversity.

- Maize boffins move on to RNA. Hard row to hoe.
- The coolness of hybrids. No, not the cars. Includes crop wild relatives.
- Bioversity makes the case that cacao is charismatic. Hard row to hoe.
- IITA tries to crowdsource banana production data. Hard row to hoe. BTW, why not include variety information? Well, maybe they will.
- Jatropha rebooted?
- The history of barley water. Surprisingly weird.
- Cory Bradshaw’s presentation on the global erosion of ecosystem services. A quick look reveals little on that often overlooked service: the provision of diversity for agriculture.
- The importance of coca in Andean culture.
- Chinese medicinal herbs doing just fine in North Carolina.
- FAO hunger report parsed by The Guardian.
Nibbles: Kew, Diversity, Allanblackia and Acacia, Pulses, GIS, Poverty, Early morning flowering, Agrobiodiversity and climate change, Breeding, Genebanks, Perenniality, Blogs, AGRA, Potato diversity, Witchweed, Mexican potatoes, Salvia, Old Sicilian chestnut, Tropical maize
- Guardian has whole piece on the importance on Kew’s collections without once mentioning Millennium Seed Bank. Anyway, the Paris herbarium is not so bad either, though they are no match for the Kew press machine.
- Hybridization is good for plant diversity. Well, yeah. What am I missing here? Oh and here’s more about things that maintain variation, and more still. You see what I did there?
- Allanblackia is the next big thing in agroforestry. Which probably means its name will soon be changed.
- Conclave meets to discuss
election of next Popepulse productivity. - Videos from Africa GIS week.
- Meeting to review 10 years of research on chronic poverty. Must have been deeply depressing.
- Helping rice to keep its cool. A crop wild relatives story.
- “The Ministry of Science and Technology should emphasize the need to undertake research programmes on unexplored and underutilized crops as these could constitute the genetic base for genes for improved nutritional quality of foods.” In India, that is.
- “We need to mine that diversity to provide genetic material in an adapted background more readily to be used by plant breeders.” From CIMMYT. How many times have I heard that? Here’s my problem: who will do it?
- That IRIN feature from a few days ago recycled with a new pic. Which is of a genebank not included in the list in the text. The person shown is my friend Dr Jean Hanson, recently retired head of the ILRI genebank.
- DIY perennial cereals.
- “Biodiversity scientists and agricultural scientists have tended to approach their interests in very different ways. I think there’s a lot we can learn from each other.” Wait, what?
- Another best biodiversity blogs list. Ahem.
- A “very clear action plan” for a ‘Green Revolution’ in Africa emerges from AGRA meeting. You will however look in vain for the details on the scidev.net piece.
- The last Inka treasure. Yep, the potato.
- Boffins find anti-Striga gene. No, not really, settle down.
- Rachel Laudan is really rude about Mexican potatoes.
- Cur moriatur homo cui salvia crescit in horto? Good question.
- Finding the 100-Horse Chestnut.
- Getting to grips with photoperiod sensitivity in maize.

- Climate change ain’t going to be good for cattle.
- But will be fabulous for breeders of drought-resistant maize.
- A fifth of Africa’s freshwater plants and animals threatened. How many of these are important to local people’s nutrition and health? A lot, I bet.
- Just a couple guys, modeling the spread of maize genetic diversity in the Americas.
- Uganda turns to wild relatives for new rice varieties.
- Toward Sustainable Agricultural Systems in the 21st Century recognizes importance of agrobiodiversity. Good to know.
