Assuming genebanks

Most crop geneticists agree that enrichment of the cultivated gene pool will be necessary to meet the challenges that lie ahead. However, to fully capitalize on the extensive reservoir of favorable alleles within wild germplasm, many advances are still needed. These include increasing our understanding of the molecular basis for key traits, expanding the phenotyping and genotyping of germplasm collections, improving our molecular understanding of recombination in order to enhance rates of introgression of alien chromosome regions, and developing new breeding strategies that permit introgression of multiple traits. Recent progress has shown that each of these challenges is tractable and within reach if some of the basic problems limiting the application of new technologies can be tackled.

That’s from Breeding Technologies to Increase Crop Production in a Changing World, part of the recent Science special feature on food security. Sure, the challenges of use are tractable. But what if those germplasm collections are inadequate in their coverage, accessibility, management or funding? As ever, genebanks are pretty much taken for granted in these sorts of discussions.

Getting breeders to focus

Really, who’d be a breeder. Everybody’s telling you what to do all the time. There are those famous “climate-ready” varieties everybody says they need. Plus on top of that, every single-issue lobby group is also making its own demands for tailor-made varieties. The organic or conservation agriculture crowd want varieties adapted to those conditions. People who think the future is mixed crop-livestock farming want dual-purpose varieties. And so on. What’s the poor plant breeder to do?

Well, she might read a new paper in Food Security for a start. Waddington et al. have identified the top ten production constraints for six major staples in 13 farming systems in sub-Saharan Africa, South Asia and East Asia and the Pacific, based on a survey of over 600 experts. They call their paper “Getting the focus right.”

The survey found significant yield gaps for smallholder farms, which were largest for sorghum, cowpea and chickpea, and large in the marginal, drier systems, particularly in Sub-Saharan Africa. All categories of production constraint—abiotic, biotic, management and socio-economic—were important contributors to yield gaps. A great diversity of specific constraints was reported for the crops in the different systems. The specific production constraints that were most severe and widespread for wheat and rice involved the deficiency, high cost and poor management of N fertilizer, soil fertility depletion, inadequate water management and drought stress. Weeds, soil degradation and drought were the most severe constraints for sorghum. Various insect pests and diseases and the high cost of their control were the major constraints for the legumes. Marketing and finance problems, and some specific biotic constraints, were the main concerns for cassava. The diversity of these important production constraints offer the agricultural research and development community an array of opportunities for solutions.

Some of these opportunities will have to do with improved agronomic practices, no doubt. But that will still leave a lot of work for breeders, in particular in the CGIAR system, for whose Generation Challenge Programme the work described in the paper was done. It will be interesting to see to what extent the varieties they develop over the coming years address the challenges identified in this paper. But by the time the next cycle of assessment of improvement programmes comes around, the constraints will have changed. Who’d be a breeder.

Speaking truth to Slow Food

ResearchBlogging.orgSlow Food is against standardization, right? Slow Food is for diversity, right? Well, sort of. That is certainly the rhetoric, but a paper by Ariane Lotti in Agriculture and Human Values 1 suggests that the practice can be rather different.

Lotti, who’s something of an insider, analyzes one of Slow Food’s projects in detail and comes to the conclusion that the organization is not as “alternative” as it claims, or believes itself to be. How can it be, when its imposition of production standards mimics the food system it purports to undermine? How can it be, when its taste education efforts can exclude “not-so-good-tasting foods…, potentially eliminating a part of the agrobiodiversity and associated processes that Slow Food is trying to save”?

Too harsh? A paragraph from the conclusion is worth quoting at length.

It may seem as if I am expecting Slow Food to do the impossible and protect agrobiodiversity while not engaging the structures of the conventional system, not creating a market for its exceptional products, and not trying to convince people of the importance of taste in the food decisions they make. Rather, I have tried to do something the organization has so far ignored; I have tried to take a critical look at the ways in which Slow Food attempts to achieve its mission and the effects of its activities. This is lacking in Slow Food and other alternative agriculture organizations, perhaps because a critique is often assumed to be a threat to a movement’s fragile existence. Without a critical examination of an organization’s activities, however, unintended and potentially negative effects are overlooked.

And of how many similar — and not so similar — organizations could something similar be said! Lotti longs for a middle way — no Cartesian dualist she.

…the binary of fast food and slow food ignores how the two extremes are related within the same agriculture system. This relation, in the case of the Slow Food organization, does not lead to a combination of the two to create what Mintz (2006, p. 10; emphasis in original) refers to as “food at moderate speeds”; that is, foods with the availability of fast foods and the characteristics of slow foods.

To truly fulfill its potential Slow Food needs to stop thinking of itself as somehow apart from — above — the conventional food system. Referring to the Basque pig keeper who was the subject of her analysis, Lotti points out that…

Pedro is not just a producer of Slow Food Presidium pigs and meats; he is a protector of global diversity and genetic resources. The industrial pig farmers, when they find themselves in a genetic corner with only conventionally-bred pigs to work with, turn to farmers like Pedro. The industrial pig is tasteless, and when the participants of the National Swine Improvement Federation Conference decide that they want to provide consumers with a “positive taste experience,” they go to farmers like Pedro, who raise non-industrial pigs, to look for taste (Johnson 2006, p. 54).

Closer attention to context and a critical, reflexive look at its efforts will “help the organization engage, address, and challenge more effectively the structures that undermine the continued production of the diverse catalogue of breeds and varieties with which it works.”

Will Slow Food slow down for a moment and listen?
