Agricultural Biodiversity Weblog
Agrobiodiversity is crops, livestock, foodways, microbes, pollinators, wild relatives …
Dave Wood muses on the successional stage of crop progenitors and the origins of agriculture:
…if early crops were directly derived from massive pure stands of wild relatives, then such crops have an ecological heritage of stability. If so, we can now stop worrying about stability based on diversity in agro-ecosystems and start worrying about just what factors once determined the obvious stability of climax vegetation of crop relatives of our major cereals.
Two stories of collaborative crop improvement — past, present and future — and the genebanks that underpin it to end the week with.
From an IRRI press release out today on IRRI’s collaboration with the Philippines:
Filipino farmers have adopted more than 75 IRRI-bred high-yielding rice varieties since 1960, have greatly improved their fertilizer and pest management strategies, and are implementing water-saving technologies.
It is telling that a particular point is made of the Filipino material in the IRRI genebank.
…in the International Rice Genebank housed at IRRI, 4,670 rice samples from the Philippines are conserved, including 4,070 traditional varieties, 485 modern varieties, and 115 wild relatives — all are available to share with Filipino farmers and scientists.
And from USDA’s Agricultural Research magazine, Feb. 2010 edition:
Of 1,768 heirloom wheats submitted since 2005, only 78 (or 4.4 percent) showed resistance to Ug99 at the Njoro site. Still, the prescreening led to identification of more Ug99-resistant wheat accessions than would’ve been achieved from sending randomly selected accessions for testing, says Bonman. This is evidenced by the fact that 7 percent of wheat lines resistant to U.S. races showed rust resistance in Kenya, yet only 1 percent of randomly selected accessions did.
I’ll be travelling for the next couple of weeks and blogging may be sparse.
I haven’t seen official figures on production or acreage — I’m not even sure if they exist — but if internet buzz and celebrity hype is anything to go by we’ve clearly been going through a revolution in vegetable gardening during the past couple of years. Well, would you believe a resurgence of interest? Schools are certainly interested. Michelle Obama is, famously, interested. The next step will no doubt be the digging of tilapia ponds on the White House lawn.
Just today there were pieces on this from the US and the UK. But what I would really be interested to know is to what extent all these “new” gardeners, including the First Lady, are using heirloom seeds. Is there demand for them? And if so, is it being met by supply?
The Royal Horticultural Society has put out a call for heirloom vegetable seeds in Wales. Is it because it fears for their continued existence, or because enough seed is not available to meet sky-rocketing requests?
Seeds discovered through the scheme will be redistributed through local seed-swaps and also through the Heritage Seed Library run by Garden Organic in Coventry.
Given the recent news about the “official” national vegetables genebank in the UK, one does have to be thankful for things like the Heritage Seed Library, and its American cousin Native Seed Search. Maybe Michelle can be persuaded to Adopt-a-Crop.
Is it me or has there been a lot on the tubes about aquaponics lately? There was the thing about growing cucumbers and fish in the badlands of Alberta. And that other thing about shivering tilapia in a backyard Thunderdome in the middle of snow-bound rural Connecticut. Classes in the subject at the New Vista High School. A youtube channel. And a blog, natch. Maybe it’s time to dust off those utopian visions of urban fish farms vertically integrated with up-market sushi restaurants.
Public funding for extension services and agricultural research that improves productivity and yield had to increase rather than relying upon genetically modified organisms.
From the head of UNDP? What kind of a crazy mixed-up world are we living in?
