- First Law of Geography valid after all.
- Multiple domestication of the horse in China.
- The Atlantic has a weird food map. What does it mean? Answers on a postcard, please.
- IITA tells farmers about its core collections, among other things.
- Bhutan and Thailand collaborate on agrobiodiversity conservation.
- Details of Tom Wagner’s European Tour. He’s the amateur breeders’ breeder.
- Tomatoes thrive on urine diet. Not a piss-take.
Conclusion: the First Law of Geography applies to diversity between fields, to contintental scale diversity, but not to the intermediate level, where market locations, ethnicity, etc. tend to have more influence than just the distance farmers have to travel.
But I would guess Tobler is still right if we measure distance in terms of travel time, etc.
