Hundreds of 100 questions

Gosh, it’s difficult to keep track of this stuff. There’s been an explosion of “one hundred most important questions facing X” initiatives in the past couple of years. These are the ones I was able to track down, listed in no particular order, but there may be others out there, in which case let us know.

I think the only one we actually blogged about here was the plant science one.

Anyway, I bring all this up because I’ve just heard that Professor Jules Pretty from Essex University is now spearheading an effort to summarize the world’s agricultural challenges down to the top 100 priority questions. Of course, the most interesting thing about these lists will be the intersection among them. Talk about bang for your buck.

Aurochs alive and well

Well, not quite. But some of their DNA is. A paper just out in PLoS ONE has found two mitochondrial DNA haplogroups (the ones labelled R and P in the diagram below) which apparently got into Italian local breeds from “European aurochsen [haplogroup E] as the result of sporadic interbreeding events with domestic herds grazing in the wild.” Some of these breeds are rare and marginalized, though, so even the last remnants of the aurochs might be in danger.

Semi-naked chicks go wild on Crete

“Eeyew. What’s wrong with that chicken?”

We were sitting on the shaded verandah of Nico, a lovely man who, after training as an architect in the US, chucked it all in to live off the grid and as sustainably as possible in a converted hovel in the west of Crete. No electricity, no running water, a wild garden and wilder chickens foraging through it.

Naturally I peered at the chicken, and there it was: naked-necked as I live and breathe.

“Golly, a naked-necked chicken, here on Crete.”

Nico, meanwhile, was answering my friend, and explaining that it was that way naturally and didn’t seem to be any different from the other chickens in his flock.

I waded in with information about the naked-necked chickens of Transylvania and elsewhere, citing the very latest thoughts on the subject, to-whit:

The use of single or combined dominant genes for feather restriction (Na) and feathering structure (F), as well as the sex-linked recessive gene for reduced body size (dw), has been found to be particularly relevant for the tropics (Horst, 1989; Haaren-Kiso et al., 1995). Research into the effects of these genes on economic factors has been undertaken in Malaysia (Khadijah, 1988; Mathur and Horst, 1989). For example, the feather restriction (Na) or Naked Neck gene results in 40 percent less feather coverage overall, with the lower neck appearing almost “naked”. This considerably reduces the need for dietary nutrition to supply protein input for feather production, and protein is a limiting factor in many scavenger feed resource bases. Barua et al., (1998) has reviewed the available information on the performance of indigenous Naked Neck fowl in the hope that it will draw the attention of scientists worldwide to its interesting characteristics and facilitate future research.

I asked Nico whether the naked-necked birds were more efficient egg layers, or suffered less in the heat, but he didn’t know. I said I’d be happy to return to conduct a thorough investigation, but I haven’t had a reply yet.

The photo took some doing too, the birds treating me as an overlarge predator definitely up to no good. Which they should.

Featured: CWRs and protected areas

Our mate Danny weighs in on CWRs and protected areas:

Maybe what is required is a more dynamic approach to CWR conservation… A more holistic approach to increasingly mobile target areas.

And yes, he has some details.

EU Conference on Seed Law

We’ve blogged often about the EU’s seed regulations 1 and we continue to keep a watching-eye on developments. So we were very pleased to receive a report from Isabel Lopez Noriega, a policy specialist at Bioversity International, about a conference on Ensuring Seed Availability in the 21st Century, held in Brussels on 18 March 2009. Doubly pleased, because she agreed that we could post it here. Thanks Isabel.

The EU registration and certification system is built around two basic conditions: first, plant varieties have to be distinct and meet certain level of uniformity and stability (DUS conditions, for distinct, uniform and stable). In addition, the EU legislation requests varieties to show their satisfactory value for cultivation and use (VCU).

Civil society organizations representing small farmers, organic food producers and environmentalists have criticized EU legislation because these basic requirements do not take the needs and practices of small producers and amateurs into consideration and may go against genetic diversity conservation principles in general. Landraces and varieties developed by farmers and others may not meet DUS and VCU requirements. Very often, valuable family populations developed by farmers do not pass the uniformity test due to their heterogeneity. This characteristic offers better resistance to biotic and abiotic stresses, but the strict uniformity rules prevent the variety being sold in the European market. Another common limitation for small farmers wanting to commercialize their varieties’ seeds is that they cannot afford the costs and long procedures required by the registration and certification processes. In addition to limiting the opportunities for farmers to obtain revenues from the varieties they produce, this situation results in less genetic diversity available for farmers in the common European market and may ultimately threaten diversity on farms.

Aware of the fact that the scenario which inspired current legislation has changed and that, nowadays agricultural production faces different problems, the European Commission decided to conduct an external evaluation of the EU legislation on the marketing of seed and plant propagating material in 2008, with the aim of establishing how effective and efficiently the legislation has met its original objectives and identifying its strengths and areas for improvement with regard to potential new challenges affecting this field, including genetic diversity conservation. As part of this exercise, the external evaluators consulted a range of stakeholders and experts through surveys and face-to-face interviews. 2 Approximately 130 people representing different sectors involved in agricultural production attended the conference to discuss the results and recommendations.

When assessing the impacts of EU legislation on different elements of agricultural production, the evaluators asked stakeholders about the effects on the preservation of plant genetic resources in the EU. According to the consultation’s results, most stakeholders consider that the legislation has had a positive impact, although they did not provide any evidence.

It is important to highlight that the evaluators’ methodology had some important limitations that hindered the participation of certain types of users. For example, the questionnaires were available only in English and only on-line (except for those stakeholders who were directly addressed by the evaluators). These limitations made the evaluation tools unfriendly for small farmers in remote areas of Europe. It is also not clear to what extent evaluators consulted research institutes and universities.

The Commission has already announced that the current legislation will experience a profound reform. If the evaluation’s results inspire the reform of the EU seed law, it is difficult to predict whether the need to maintain a healthy level of plant genetic diversity in the market and on farmers’ fields will be taken into consideration by the new legislation and whether this need will be translated into a suitable treatment for highly diverse varieties. Most of the users and producers who participated in the evaluation do not consider that certain objectives closely linked to diversity conservation (such as the protection of the environment, low-input agriculture and farm-saved seeds) should be priorities for the new seed law in Europe. At the same time, they do claim that the new legislation facilitates the availability of a broad range of varieties in the European market. Although these two positions seem to be contradictory, this is not always the case as a greater number of varieties does not automatically mean a greater genetic diversity. Many of the improved varieties of the same crop currently available in the European market do not differ much among themselves at the genetic level. This shows that diversity cannot be measured by the number of varieties alone.

Although small farmers and organic farmers’ organizations make themselves heard in current dialogues and negotiations dealing with seed legislation, their interests are still considered marginal by the European Commission in comparison to those of seed companies and large scale producers, who represent almost the whole volume of the European seed market. This sector does not seem to advocate a radical change in the current legislation. The vast majority upholds seed law in relation to the traditional principles of productivity, quality and transparency and is reluctant to include new objectives such as sustainability. In general terms, they are in favor of maintaining the current registration and certification schemes, but adjusting them according to the type of crops. In both the evaluation’s results and at the conference seed companies and medium and large scale producers clearly stated that they would not like to see further differentiations according to the final use of the seed or the type of users, which would perhaps be the best way to protect small-scale producers’ interests and, consequently, diversity.

As the Commission and the EU member states develop a new seed system for Europe, the impact of such a system on plant genetic erosion must be subjected to serious and profound research. A number of existing studies and the results of the evaluation’s survey may offer some preliminary conclusions, but these need to be validated through in depth analyses.
