It is all too easy to concentrate on the bad news out of Africa, so for a change on Biodiversity Day I’d like to point to three feel-good stories about how Africans are using biodiversity to make better lives for themselves. Via Timbuktu Chronicles come pieces on traditional medicine in Mali and local leafy greens in Kenya and Tanzania. And there’s also a World Vision report out today on how farmers in Tanzania are turning to an unusual crop.
New kids on the blog
The International Food Policy Research Institute seems to have a blog: blog world hunger. It started a while ago, by the look of things, but has lately shaken itself, rubbed the sleep from its eyes, and started wandering about the room. Alas, it needs a tweak or two. I tried to leave a comment and no matter how fast I typed it insisted my message had timed out as a result of inactivity. Maybe you’ll have better luck. There’s an ongoing discussion of agriculture and shifting climates, which seems appropriate today.
Growing grains
Blogger Mustard Plaster has decided to delve into the magic of growing cereal grains with hull-less oats and hull-less barley. She complains that there isn’t much advice on gardening books, and she’s right. As one who has been there and done that, I can recommend only one book: “Small-Scale Grain Raising” by Gene Logsdon. And to tell the truth, even that is not much use for the gardener, although it is a fun read. Freshly ground, home grown cereals; that would take a lot of beating at breakfast time.
Happy International Day for Biodiversity
Yup, it’s the day we wait for each year. The day that the Secretariat of the Convention on Biological Diversity (CBD) has set aside to celebrate. And this year, it’s all about Biodiversity and Climate Change. Yay! We learn that an increase of only 2.5 degrees C will mean “50 million more people facing hunger” and that “conserving certain species such as mangroves and drought resistant crops can reduce the disastrous impacts of climate change effects such as flooding and famine”.
If you were looking for more on biodiversity and agriculture, look no further. Our friend Andy Jarvis, along with colleagues Annie Lane and Robert Hijmans, has published a paper looking at how climate change will affect the survival of crop wild relatives in three species: peanut, cowpea and potato. There’s a press release here (and coverage in Reuters). Bottom line: things don’t look good.
Climate change affects agriculture from at least two directions. It will require diversity as a sources of traits to cope with the effects, by breeding new varieties. And yet it threatens that very diversity with extinction, especially when, like the peanut, you can move your seeds less than a metre each year in search of more suitable growing conditions.
Two solutions present themselves, which is a nice symmetry. Try to ensure that natural conservation efforts in parks and the like are designed with wild relatives in mind, giving slow-coaches like the peanut a helping hand if necessary. And collect more samples of agricultural biodiversity from the wild and from farmers’ fields to store in genebanks. Alas, this latter option has become more and more difficult as countries increasingly fear the rip-off tactics of bio-pirates. And who’s to blame for that? Step forward the CBD.
It’s an ironic world, eh?
Fermenting revolution
Sandor Katz wrote a classic book a few years back about the history and practice of fermentation as a technique for preparing, enhancing and preserving food. Catch an interview with him at Grist. Let’s not forget that agricultural biodiversity includes that pesky microflora.
