Some new directions, some not so new...

Well, it has been months since I have posted anything on this blog and for the most part it would seem completely dead, but no it is not... Truth be told I have been finishing up classes, passing my qualifying exams for candidacy and working to develop my research program for completion of the PhD.

As some of my later posts indicated I have taken an interest in sustainable agri-food systems, but in many ways I was trying to change some of my interests to fit the literature available to me. However, with my background in IT and the social sciences coupled with my new knowledge in environmental systems it seems appropriate to find a way to integrate all of these elements into some sort of coherent program of research.

With that in mind I began looking for references in the literature on agri-food studies that discuss the role of technology and the internet in particular and their respective influences on the rise of alternative agri-food system projects. This fascinating search revealed one single source and only scant hints at the role of new information and communication technologies for informing civic agriculture.

So to complete the PhD I will be doing 3 empirical research papers with the intent of publishing them in some journals. The first two deal directly with the role that ICTs are playing in supporting the emergence and spread of civic agriculture. The third paper has yet to be approved but I intend to do an ecological footprint analysis on a hypothetical scalability of local agriculture on the Palouse.

The key to this eco-footprint analysis will be the focus on spatial variation with respect to landscape. It is my hypothesis that ecological variations across spatial dimensions will invariably lead to different outcomes with respect to the sustainability of local agri-food systems.

For instance, it cannot all be about GHG emissions and food miles. For instance, biodiversity, water consumption for food production and soil quality all relate to sustainability and therefore should be included!

First Iteration - a system dynamics model of food vs. biomass

I have been doing a lot of research lately and as a result my blog has been relatively sparse on posts. However, this research has enabled me to develop a very crude model of the impact of biomass production for fuel on food yield within a finite space of land.

This model is by no means close to representing the various dimensions needed to make it worthwhile. However, this is my blog and I wanted to post what I'm working on at this moment.

Keep in mind this model does not account for:

• Demand on food due to growing population
• Demand on biofuel (biodiesel specifically)
• Energy requirements for planting and harvesting
• Greenhouse Gas Emissions
• Carbon Taxes (as incentives for adopting biofuel)
• Rate of Land Degradation
• Price Fluctuations in Petrol Markets

Now, these aren't all of the parameters that will be added to the model, but they are some of the most important ones at this stage. The idea is to provide this general model that can be adapted to fit with various farming systems, ie mainstream industrial farming represented as a mono cropping system and alternative multi-cropping systems where there a number of various crops with differing values competing for resources. Each system present different management practices and therefore different energy consumption patterns.

Over the next few months this will represent a central theme on my blog as this is what I'm working on... imagine that!

Anyway, here is the current model structure (I will post the equations in another post but this is hopefully a useful visual):


Here is the output:

The Question....

What is the question? Well, that is a great question! But, I'm thinking more specifically about the question driving my interest in alternative agricultural systems.

Are alternative agricultural systems truly more sustainable in terms of reducing GHG, promoting economic viability of farms, and producing affordable, safe food, than more industrialized (modern) farming systems?

There is a lot of rhetoric being published from those arguing for a "perfecting" of modern agricultural processes, strategies and technologies, just as there others arguing for the alternative. But, when we move past the rhetoric we are still just as confused as before regarding the sustainable path to present and future food security.

Rather than proponents of each side of the debate continuing to ignore the other, it is perhaps time to engage in some serious comparative analysis that incorporate economic, environment and social dimensions. Understanding the complexity of interdisciplinary research, "most" of these studies are glaringly absent from the dialogue. It appears that one dimension supersedes all the others in current studies. It is usually economics, with environment coming in second and social coming in a distant third.

I think this needs to be changed if we are going to start identifying appropriate policies for a sustainable future, especially one where we can eat!
