Land sharing or sparing?

That is one of the questions addressed by a paper in Journal of Applied Ecology which looks at the ecogeographic distribution of organic farming in the UK. “Land sparing” means excluding land from intensive agriculture to protect biodiversity. “Land sharing” is a contrasting strategy which would make all agricultural land better for biodiversity. The study recommends

…continuing to use intensive agriculture to meet our food production targets, but using organic farms in suitable areas to provide islands of biodiversity, as well as a smaller amount of food.

So the vote is for land sparing. Ok, fair enough. What gets me, though, is that, as usual, it is only the effect of agriculture on the surrounding wild biodiversity that is being considered. What about the biodiversity that is an integral part of the agricultural system itself? Doesn’t agrobiodiversity count for something in all this?

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.
