Starch grains and the origins of agriculture

A couple of papers discussed here and here (among other places: the chili pepper story in particular has been getting a lot of media coverage) describe how the minute, species-characteristic starch grains found in micro-crevices on stone tools and cooking utensils recovered from archaelogical sites are being used to study the domestication of crops as varied as maize, cassava and chilies in the Americas. The findings are pushing back the timing of domestication and suggesting that wet lowland areas were more important in the process than previously thought. Jeremy blogs on the chili angle at greater length here. No word on the past of cactus cultivation, at least in these papers, but this piece suggests its future may be troubled.

Brazil to market biodiversity

Under an Environment Ministry initiative in Brazil research groups have selected 775 species to encourage production and hopefully develop major markets. Read about it here:

Five books will be published this year, each dedicated to one of the five major regions of Brazil, containing the knowledge that has been accumulated about these “plants of the future”. Seminars for the business community will be held to spread the word about the potential of these plants, which are ornamental or used to produce foods, beverages, medicines, oils and perfumes.

Award for The Land Institute

Wes Jackson, the pioneer of perennial prairie polyculture, is to receive the 6th Environmental Award from Prescott College in Arizona for the work of The Land Institute, according to a press release. I’ve always had a lot of respect for Jackson and his vision of what agriculture could be, really learning from nature to craft a more sustainable farming system. It’ll be a while before we are “growing granola” in his immortal phrase, but The Land Institute’s experiments on mixtures of four or more species, drawn from different families to make optimal use of resources, are proceeding apace. The Prescott College award is by no means the first Jackson has received, but every bit helps to draw the attention of mainstream research to his ideas. Which is why I’m blogging it, I suppose.

Nuts

I just heard a programme on the BBC World Service in the One Planet series called “Nuts.” It looked at the problems encountered in developing the Brazil nut as a source of income for poor Amazonian farmers. Unfortunately, it appears that some very tight – some would say unreasonably tight – EU regulations about levels of aflavotoxins are preventing exports. There’s part two next week. The website for the One Planet series is here, but this particular programme does not seem to be online yet. I’ll keep looking out for it. Coincidentally, WWF also has a long piece on the Brazil nut out today, which you can find here. International Trade Forum had a piece on Brazil nuts here in 2004.
