Shepherds and their flocks trek through Europe

Evelyn Mathias of the League for Pastoral Peoples and Endogenous Livestock Development just posted an interesting piece on DAD-Net. Unfortunately I was not able to find a web page to link to, so I take the liberty of reproducing the post in full here.

They are good-natured, produce tasty meat, and their wool gets turned into sweaters. Everyone knows so much about sheep. But few people know about the benefits that sheep provide through grazing. As they move from place to place, mobile flocks maintain the ecology, so conserving many threatened plants, animals and insects. The landscapes they create enhance the quality of life for local people and tourists alike.

Grassland that has been extensively grazed in a controlled way is an excellent water filter. It protects the soil from wind and water erosion, stores a huge amount of carbon, and converts carbon dioxide into oxygen in winter when trees no longer have leaves.

But grassland must be maintained through grazing – otherwise it will be overrun with brambles and scrub, which lack many of the advantages of grasses. Mobile flocks of sheep are an important way to conserve these landscapes.

To raise awareness of the advantages of mobile livestock production, Europe’s shepherds have organized a sheep trek across Germany, Belgium and the Netherlands during the summer of 2010. The trek aims to draw attention to the contribution that mobile herding makes.

“Shepherds all over the world face similar problems”, says Günther Czerkus, spokesman for the German shepherds association. “Too much bureaucracy, and an increasing number of restrictions that make it more and more difficult to maintain a mobile herd.”

Shepherds in Europe also find it difficult to market their products. Wool prices are so low that it is not profitable to shear the sheep. And the market for meat is dominated by imports from New Zealand. Czerkus hopes that the trek will encourage consumers to buy home-grown lamb.

The trek will start in Berlin on 5 June and end at the “Green Land Day” (Grünlandtag) in Trier on 16-17 October. The trek will be a kind of a relay walk, with each flock and shepherd covering a certain distance and then handing over to another flock for the next stage. Accompanying vehicles will manage traffic and distribute information materials.

Special events in Paderborn (1 August), Duisburg (21 August), Brussels (16 September) and Trier (17 October) will highlight the contributions of sheep. Other events may be organized through hout the trek. The trek will provide excellent opportunities for school classes to learn about agriculture and ecology in general, and mobile herding in particular.

A similar but smaller trek took place in Belgium in 2008. The webpage from this earlier trek gives an idea of what a trek might look like.

Nairobi’s International Day of Biodiversity in pictures

Taz, who describes himself on his blog as a Kenyan science writer, was at the National Museums of Kenya on the occasion of the International Day for Biodiversity, and he kindly left a comment to that effect on our short post on that subject. His own description of the event includes some great photos. Any other reports, from Nairobi and elsewhere?

LATER: Susan MacMillan of ILRI also has some photos from the Nairobi celebrations on her Facebook page.

100% sure that 75% is incorrect

A familiar number was much bandied about during the otherwise wonderful celebration that has been the just-ended Settimana della Biodiversitá here in Rome. We have lost 75% of the diversity of crops during the past century, we were repeatedly told. So I will take this opportunity to repeat from my part that while for all I know this number may indeed be accurate, we have no evidence to that effect. Nobody has counted up all the tomato heirlooms lost in Italy, all the bean landraces lost in Mexico, all the mango varieties lost in India, all the taro clones lost in Papua New Guinea, divided by the number of those things that there used to be, repeated the feat for all other countries in which these crops are grown, 1 done the whole thing again for all other crops, taken an overall average and come out with 75%. In fact, as we have said here before, that 75% number is probably an extrapolation from one, probably hardly representative, data point. We should recognize this fact, admit that we don’t know how much crop diversity has been lost overall, quote what numbers there are for genetic erosion with circumspection, and go out and get better numbers.

Peking presumably planning to plant potatoes

A short and barely comprehensible article in the People’s Daily Online alerts us to the fact that Beijing is to become a “seed-planting capital in the next few years,” on the back of its “currently reserved over 390,000 national-class germplasm resources, ranking second in the world.” Apart from what that means, I also wonder whether the planned planting programme will include potatoes, whose cultivation in China is apparently plagued by “inadequate germplasm resources for cultivar development, the lack of high quality seed potatoes” and various other problems.
