Sharing and genebanks

Gathuru Mburu, coordinator of the African Biodiversity Network in Nairobi, gets interviewed by IPS about AGRA and all that. He ((I think he’s a he, but I’m not entirely certain.)) says a lot of sensible, though not particularly new, things about the Green Revolution approach to African agricultural development.

What we need to do in Africa is to promote ecological farming, promote farmer varieties of seeds and even support or pass laws that support local farmers and their indigenous plant breeding innovation.

True, if perhaps not the whole truth.

And in India, there are so many people who have realised that the way to save the population of India is not going chemical, but going back to the natural ways, the ecological farming systems. And they are reclaiming, they are recuperating the seeds and the culture around the seeds and they are bringing them back [into use] and they are sharing.

We have to bring back that culture. It’s not just the seeds but the culture around the seeds. It’s the value of sharing — in the corporate world, there is no sharing, but in Africa in our own indigenous cultures, seeds were not sold, they were shared.

Interesting that about sharing. Though I think that particular culture is alive and well in Africa. I wonder if he would extend it to the international level. Or maybe there are limits to sharing? But let’s explore further the bit about recuperating.

At the moment, what is happening in Asia is that farmers are actually going back, retracing what they have lost in terms of biodiversity. And it is an uphill task because the knowledge of managing that biodiversity is gone. Because the elders who have that knowledge are no longer there. The people who are farming today have grown up with monocultures; there are very few people who can take farmers back in Asia, back to where they came from before the Green Revolution.

An uphill task. Recuperating seeds is not an easy thing. They have to look for them, sometimes they may have to even buy the original seeds from the few people who still have the original varieties. And all this is happening because they lost their indigenous seeds to the Green Revolution, which favours monocultures of improved seeds only.

Well, what about genebanks? Recuperating seeds is what they’re there for. People may need to look no further than Muguga, where the Genebank of Kenya is located, to get back the seeds they lost. Or something like them anyway. Assuming they were shared with the genebank in the first place.

Movable feasts

There’s no doubt that climate change poses a huge challenge for in situ conservation of species — including crop wild relatives — in protected areas. I mean, what is one to do, move the park around to follow the species as it tracks the climate? Well, that’s exactly the type of thing that marine biologists are now contemplating for Marine Protected Areas (MPA):

Maybe they’re bigger, … or spaced like stepping stones so species can hopscotch to higher latitudes. Perhaps they’re not tied to a geographic location at all, but follow conditions scientists know are important.

We saw in earlier posts that assisted migration could be another approach. A couple of things are for certain. If protected areas are aimed at individuals species, as opposed to the landscape or ecosystem, we’re going to have to rethink how we define and manage them. And ex situ conservation will be an increasingly important complement to them.

“We set aside parts of the world as if it’s going to be static,” says [Dee] Boersma, at the University of Washington, Seattle. “But the one thing that’s constant is change.”

Meta-analyzing ecological agriculture

Meta-analyze the meta-analyses on ecological agriculture and this — at least according to Lim Li Ching, a researcher at Third World Network — is what you get:

It is clear that ecological agriculture is productive and has the potential to meet food security needs, particularly in the African context. The International Assessment of Agricultural Knowledge, Science and Technology for Development concurs that an increase and strengthening of agricultural knowledge, science and technology toward agroecological sciences will contribute to addressing environmental issues while maintaining and increasing productivity (IAASTD, 2008). Moreover, ecological agricultural approaches allow farmers to improve local food production with low-cost, readily available technologies and inputs, without causing environmental damage.

Miguel Altieri thinks that small farms is where the most ecological and sustainable agriculture is predominantly taking place, and that we need to support that. He repeatedly mentions that they are havens of agrobiodiversity, but he doesn’t mention another meta-analysis that shows that small farms are diverse farms.

LATER: From Brazil, “how family farmers may have benefited benefit from the implication of large retail chains in the organic sector and how an economically and ecologically outstanding agriculture may arise from these circumstances.”

Inter situs conservation unveiled

Following our recent exchange of views on assisted migration, Prof. Vernon Heywood has alerted me to the fact that the latest issue of BGjournal (Vol. 6, No. 1, January 2009) is devoted to ecological restoration.

Amongst the many interesting articles is one on inter situ [sic] conservation which is an issue related to assisted migration. It deals with reintroduction of species to locations outside the current range but within the recent past range of the species unlike assisted migration which deals with the introduction of species (or communities) to areas not at present within their ‘native’ ranges. Both are forms of human-aided translocation of species. On a pedantic note, the correct term for the former should be inter situs not inter situ. I suppose that assisted migration could be viewed as anticipated or predictive inter situs conservation but I would not advocate using such terms.

Another article (by Dixon & Sharrock) in the same issue is on botanic gardens and restoration and includes a Box on the potential and problems of assisted migration.

Perhaps the biggest problem with assisted migration is that while we have various bioclimatic models for predicting species’ distributions under different climates we are not really able to incorporate habitat availability or predict it independently of niche models. We need to know what the habitat and species assemblage (“ecosystem”) are likely to be in the future that we are planning to introduce species into!

It’s not online on the BCGI website yet, but it soon will be.
