It may be a bit of a stretch for this blog, but I liked a recent Christian Science Monitor article on the increasing use of native plants – at the expense of exotics – for landscaping in some parts of the US. The authors credit more awareness of climate change, and in particular worries about excessive water use in ever more drought-prone areas, for this shift in attitudes.
Welsh pony in trouble?
A long article in icWales, the self-described “national website of Wales,” details the predicament of the local pony breed. Once an important part of everyday rural life – and indeed industrial life, due to their use in coal mines – more recently a children’s trekking pony, there is now limited demand for the breed. Wild herds have thus declined dramatically, no doubt resulting in genetic erosion. Does it matter? A resounding yes echoes around the hills.
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.
More sorghum for Zimbabwe
A press release from the Netherlands Organisation for Scientific Research is creating tiny ripples in the blogosphere because it suggests that fertilizer, rather than water, is what poor farmers in semi-arid regions of Zimbabwe need to improve their crops. That’s certainly one conclusion from the research of Dr Bongani Ncube, who successfully defended her doctoral dissertation 10 days ago. (Congratulations, Bongani.) More important, I think, is the demonstration that almost regardless of water, sorghum crops benefit enormously from a preceding grain legume. There’s an interaction with rainfall to be sure. In a dry year, cowpea yields more than groundnut or bambara groundnut, but sorghum is always better after a nitrogen-fixing legume. That’s not to say that farmers shouldn’t make use of a little artificial fertilizer if they can afford it. But a better strategy might be to grow a variety of grain legumes, to buffer any possible effects of rainfall, and then plant sorghum, using agricultural biodiversity instead of cash to increase the harvest.
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?
