The oldest and most common dig against organic agriculture is that it cannot feed the world’s citizens; this, however, is a supposition, not a fact. And industrial agriculture isn’t working perfectly, either: the global food price index is at a record high, and our agricultural system is wreaking havoc with the health not only of humans but of the earth. There are around a billion undernourished people; we can also thank the current system for the billion who are overweight or obese.

Nitrogen pollution from farms, vehicles, industry and waste treatment is costing the EU up to £280bn 320bn euros a year, a report says.

The study by 200 European experts says reactive nitrogen contributes to air pollution, fuels climate change and is estimated to shorten the life of the average resident by six months.

Livestock farming is one of the biggest causes of nitrogen pollution, it adds

Food: Six Things to Feel Good About

The great American writer, thinker and farmer Wendell Berry recently said, “You can’t be a critic by simply being a griper . . . One has also to . . . search out the examples of good work.”

I’ve griped for weeks, and no doubt I’ll get back to it, but there are bright spots on our food landscape, hopeful trends, even movements, of which we can be proud. Here are six examples.

1)  Not just awareness, but power | Everyone talks about food policy, but as advocates of change become more politically potent we’re finally seeing more done about it.

2) Moving beyond greenwashing | Michelle Obama’s recent alliance with Wal-Mart made even more headlines than the retailer’s plan to re-regionalize its food distribution network, which is if anything more significant.

3) Real food is spreading | There are now more than 6,000 farmers markets nationwide — about a 250 percent increase since 1994 (significant: there are half as many as there are domestic McDonald’s), and 900 of them are open during the winter.

4) We’re not just buying, we’re growing | Urban agriculture is on the rise. If you’re smirking, let me remind you that in 1943, 20 million households (three-fifths of the population at that point) grew more than 40 percent of all the vegetables we ate.

5)  Farming is becoming hip | The number of farms is at last increasing, although it’s no secret that farmers are an endangered species: the average age of the principal operator on farms in the United States is 57.

6)  The edible school lunch | The school lunch may have more potential positive influences than anything else, and we’re beginning to see it realized.

Interesting article on social group dynamics using a non-linear dynamics model. The interesting thing is can the para,meters be managed to prevent small groups fading away.  Is there a critical mass?

Nonlinear dynamics is invoked to explain a wide range of physical phenomena in which a number of factors play a part.

One of the team, Daniel Abrams of Northwestern University, put forth a similar model in 2003 to put a numerical basis behind the decline of lesser-spoken world languages.

At its heart is the competition between speakers of different languages, and the “utility” of speaking one instead of another.

“The idea is pretty simple,” said Richard Wiener of the Research Corporation for Science Advancement.

“It posits that social groups that have more members are going to be more attractive to join, and it posits that social groups have a social status or utility,” he told BBC News.

the Association of Applied Biologists

To be held at SAC, Edinburgh, UK
2-4 June 2009

The aim of this conference is to explore and identify effective methodologies, modelling and measuring techniques to analyse integrated systems. These systems are, by their very nature, complex and many interacting factors determine their development. It is now widely recognised across the scientific community and policymakers that issues such as climate change, biofuels and food security, impacts of agriculture on the environment, animal health and welfare, and agricultural policy and regulations are best addressed through an integrated systems approach. This timely and topical conference is being organised jointly by the Association of Applied Biologists, the British Society for Animal Science and the Agricultural Economics Society to discuss this rapidly developing area and share insights into how problems can be resolved. Conference participants will consider how recent research can enhance our understanding of how changes in the biophysical, economic and social environment are likely to impact on agricultural production and ecosystem services, and the wider implications for society.

The conference will consist of keynote addresses, offered papers and poster presentations and workshops that will focus on exploring the way forward.

The key themes for the conference are:

• Tools of the trade, for example integration of biophysical and economic modelling, investigation of scale, linking static and dynamic models, sensitivity and uncertainty analysis, data collection and availability, quality assurance.

• Lessons to be learnt, for example, case studies, building blocks of the system, linkages, application of models.

• The way forward, for example identification of strengths and weaknesses, deciding when integrated methodologies are appropriate.

Papers and posters from the conference will be reproduced in a volume of Aspects of Applied Biology, which will be available to delegates at the conference. Full papers will be encouraged to be submitted for publication in Annals of Applied Biology. Please send your offer to the AAB office (Email to anna@aab.org.uk; Fax +44 (0)1789 470234). Alternatively, you can submit an offer online, giving the title of the paper, authors, affiliations and a short synopsis of your paper. Click on ABSTRACTS in the left hand column, then click on the conference title. You can register your email and, after being sent a password, can upload your offer. Please indicate whether your offer is for a platform presentation or a poster.

Special Interest Group on Agriculture and Natural Resources Call for Abstracts

Frank Parkinson Room, University of Reading, 2nd April 2009

Making better decisions for the management or governance of the agricultural and related natural resource industries

We invite contributions to this meeting of broadly relevant works.

There is no restriction on techniques or class of problem solved, but the work will be of an applied nature, and that may involve a considerably innovative approach.

To raise the profile of these contributions, abstracts they will be published in the Journal of Agricultural Science, subject to editorial review. They must be of completed or near completed work and prepared in the correct style (see Journal of Agricultural Science, Cambridge generally, but a similar preprint of proceedings is available http://hdl.handle.net/1826/2471). An abstract should be 350- 400 words of text and may, in addition, contain some equations, and at least one reference, for example to a more detailed presentation of the author’s work. Microsoft Word is preferred.

Those wishing to contribute should send an abstract to:
D L Sandars (Agriculture and Natural Resources’ Meeting) Natural Resources Management Centre, Building 42a, School of Applied Science, Cranfield University Cranfield, Bedfordshire, MK43 0AL

E-mail: daniel.sandars@cranfield.ac.uk

Fax: +44 (0) 1234 752971

by Monday, 2nd March 2009.

Each talk will be of 15 minutes duration, followed by 5 minutes discussion. We will endeavour to select a balanced programme of contributions from those offered. This event is timed to exploiting synergies with the Agricultural Research Modeller’s meeting in London (contact Les Crompton, University of Reading, l.a.crompton@reading.ac.uk) the following day. If you have to travel a distance why not stay a night and do both?

Depending on numbers we may recommend that the talks form part of the latter event in London rather than the proposed standalone event in Reading.
