Rising food prices threaten on-farm biodiversity

Back in the 1990s the European Union, concerned about over-production of poor-quality cereals, introduced set-aside. Farmers were required to not grow food on a percentage of their land, currently 8%, and were paid to do so. The result was an increase in biodiversity; wildflowers, insects, birds, that sort of thing. Now, with rising food prices, there’s a proposal to reduce the area of set-aside to 0%, and conservationists are unhappy.

This is an old argument. Grow more food more intensively and you spare some “wild” habitat. I suppose the question is, how long will high food prices last? Until rain returns to Australia? Or until the world wakes up from its ethanol binge?

Biofuels backlash

Despite the lack of recent posts on the topic, I haven’t lost interest in biofuels and the food vs fuel dimension of that tussle. But there has been so much blather out there that it has been hard to make any sense of it. Focus is needed, and that’s something we find it hard to do as we flit from topic to diverse topic. Fortunately, others are less easily distracted.

The Low-input High Diversity Biofuels blog — which seems to be based at Oklahoma State University in the US, is one such. As the name suggests, it is not exactly enamoured of the alternative High Input Low Diversity approach. Several recent postings give more details. There’s one pointing out that HILD may yet gain traction: “Despite the documented social and environmental costs of biofuels, the vested agricultural interests are politically too strong. The momentum for biofuels is far too great.” Others address the recent OECD report on biofuels, making biodiversity preservation part of biofuels policy and so on. One to watch.

Use monoculture to pay for diversity

Palm oil plantations destroy the biodiversity of the forests they replace. But high-falutin’ ideas of paying farmers not to plant oil palms are doomed to failure for two reasons. First, as developing countries rush to point out, Europe and America destroyed their own forests to power their development, so who are they to ask developing countries to forego similar development? Secondly, palm oil is so profitable that very little else is likely to appeal to farmers. Lian Pin Koh and David Wilcove have a nifty idea in a recent Nature. Conservationists should invest in small palm oil plantations and use the profits to buy — and protect — rainforest.

Koh and Wilcove say that a typical mature oil-palm plantation in Malaysia makes an annual net profit of roughly $2,000 per hectare. Existing oil palm-cultivated land sells for about $12,500 per hectare, so the capital investment could be recovered in just 6 years. Thereafter, the profits from a 5,000-hectare oil palm plantation would be about $10 million, which could buy 1,800 hectares of forest each year. The forest would be set aside as private nature reserves. Furthermore, new and more sustainable palm plantations could then be established on degraded land, which is feasible, but currently not as cheap as chopping down forest.

Sounds to me like a plan.
