Smorgasbord: take what you need

Like a perfectly assembled buffet, everyone should be able to find something nourishing in Fidel Castro’s latest essay: Where Have All the Bees Gone? And Other Reflections on the Internationalization of Genocide ((Actually, I don’t know whether that is the title he gave it himself, but it’ll do)). Ranging across more topics than you can shake a stick at, he says a couple of things that I happen to agree need saying. Like criticising the modern mania for biofuels: it’s a sick joke in developed countries. As The Economist said two weeks ago, “It is not often that this newspaper finds itself in agreement with Fidel Castro, Cuba’s tottering Communist dictator. But …” ((In fairness, they were commenting on an earlier essay by Castro, but one that contained the same points))

(Disparities between Cuba’s infant mortality rate and medical services and those of the United States are not the subject of this blog.)

Then there are the bees. Here’s Fidel:

Scientists are entertaining all kinds of hypotheses, including the theory that a pesticide may have caused the bees’ neurological damage and altered their sense of orientation. Others lay the blame on the drought and even mobile phone waves, but, what’s certain is that no one knows exactly what has unleashed this syndrome.

There’s enough trickiness around without going into the mobile phone argument. I’d be happy to be proved wrong on this, but for now I’m not even prepared to link to the many, many outpourings on the subject. Let’s just say that mobile phones are the least of Cuba’s worries, with the lowest penetration of any country in South America.

Indian potato chips

Indian potato growers are turning to a new, low-sugar variety of potato because it is better for making chips (crisps if you’re British), for which there is rapidly increasing demand. Would be interesting to monitor the effect on “local” varieties, no?

Local and exotic crops in Africa

The long dry spell throughout much of February and March, caused by an unexpected El Nino that kept the main rain belt to the north of Zimbabwe, will cause serious hardship in significant areas of the country.

That’s not the only thing, of course, but an article from the Harare Herald ((Posted at allAfrica.com)) makes a plea for farmers to grow local indigenous grains such as “sorghum, mhunga and rapoko” rather than watch maize “wilt and die four years out of five”.

It is a wonderful article, making lots of good points. That food-for-work programmes should be accompanied by intensive training on growing small grains, so that those who need it most can become self-reliant in food and maybe even sell a bit for income. That modern machinery makes preparation much easier, and it isn’t expensive. That an advertising campaign could make a virtue of sadza ((Zimbabwean porridge?)) the way grandmothers made it. That there are benefits for urban consumers too. And finally, “Variety is wonderful. But we should not be rejecting indigenous grains simply because they are not “modern” or “Western”. We should be using them as well”.

I wonder whether anyone is listening?

The Ethiopian Herald, meanwhile, says green gram is becoming the crop of choice in Southern Wollo zone. A legume, green gram (Vigna radiata, maybe most familiar in the West as mung bean) improves soil fertility, ripens more rapidly and doubles or even triples incomes. One farmer is quoted as having replaced his teff crop with green gram, but if everybody does that, who is going to supply the teff flour for njera?

First study of global pollinator value

Back in October 2006 the Royal Society published an online version of a comprehensive study that was the first attempt to put a global value on pollinators. It attracted some attention back then, at The Worsted Witch, who got it from Science Daily. We missed it at the time ((Probably because the whole site was pretty new)), but as the paper version has just been published, that’s enough reason to revisit it ((Thanks to Michael Kubisch for sending the information below and the link)).

Very briefly, the article shows that 87 of the leading 115 crops depend to varying degrees on animal pollination. These 87 crops represent 35% of the world’s food production. While a few food plants are pollinated by birds or bats, the most important pollinators are, of course, honeybees, domesticated and wild. This is particularly troublesome in light of the various threats to the domesticated bee. The authors conclude that agricultural intensification jeopardizes wild bee populations and plead for more research into landscape management practices that would enhance wild bee viability.

Interestingly, I couldn’t find an actual cash value for pollination services in the article, but maybe I didn’t look hard enough.
