Is agriculture an ecosystem?

Given the amount of land occupied by farmers and farming, you might be forgiven for thinking that ecologists would at least pay it more than lip service. But no. A press release from Brown University in the US announces the establishment of the first secretariat for the International Long Term Ecological Research (ILTER) network. It explains the vital importance of long term studies in ecology, to determine trends that may well be invisible over shorter periods. And it explains the various ways in which ecosystems change over time. But does it mention agriculture or changes in agricultural biodiversity? Of course not.

Legume to remove nitrogen

Soybean field I’m still trying to get my head round this one. USDA scientists are developing a soybean variety (which they stress is not genetically modified) bred to remove nitrogen from the land.

The variety does not develop nodules, the little bumps on the root that house nitrogen-fixing bacteria. Now those nitrogen-fixing bacteria are one of the best reasons to plant legumes, because they boost soil fertility. Why would you want a legume that did not? So that animal producers could use it to solve their waste problem. I expect it makes sense in the hyper-specialized world that the USDA serves but, as I said, I’m having a little trouble with the idea.

Oil palms and diversity

It is an article of faith that intensive monocultures of genetically uniform plants are bad for biodiversity, wild and agricultural. So news that Malaysia is putting some money into a “Palm Oil Wildlife Conservation Fund to promote ideas and proposals to enhance biodiversity linked to palm oil production worldwide” is welcome. The fund will seek to promote sustainable practices and to make more use of the production of palm oil plantations, in addition to boosting biodiversity in and around plantations. There’s also talk of using palm oil to produce biofuels, a hot topic at the CGIAR Annual General Meeting.

Google Earth

I’ll be posting later this week about the importance of geo-tagging biodiversity, but for now I just wanted to point out that Google Earth Blog, an independent forum for the discussion of the things you can do with Google Earth, has a section on the environment. Many of the things Frank Taylor posts on under this tag will be relevant to the study and conservation of biodiversity. And here’s a great Google Earth application I’ve recently come across, though from another source. The Malaria Atlas Project is pulling together data on the global distribution of the malaria parasites as a prelude to modelling their spatial limits.

Green Revolution did not bypass Africa; it failed

Grain, an international NGO that “promotes the sustainable management and use of agricultural biodiversity” has issued a somewhat jaundiced review of the recent anouncement by the Bill and Melinda Gates Foundation and the Rockefeller Foundation of a new Alliance for a Green Revolution in Africa. Grain insists that the first Green Revolution did not bypass Africa: “It failed. It was unpopular and ineffective.”  The NGO goes on to say that on the evidence available, the new effort will fail for the same reasons, because the approach it adopts is unchanged.

What do you think? Do African farmers need new technology, such as improved varieties and fertilisers? Or are there other approaches that will help societies there to develop and feed themselves more effectively?
