Food growing - the big picture

   This blog promotes sustainable local food production, growing your own, growing for local communities, using local resources without fossil fuel inputs, without relying on political solutions or ideologies. It's meant to contribute to the Transition movement, not because the future of safe, affordable food is assured or doomed but because it's uncertain. Excerpts below introduce only some of the concerns in this area. Much can be done, and much is being done. This blog is not connected to any site or organization, but for a sample of current food efforts on many fronts readers can check http://foodsecurity.org/links.html . We have nothing to sell you (unless you find us at our farmers markets).

   We are fortunate to live in an age of scientific agriculture and technologically advanced food processing. As a result, the American food supply is assured, in all its abundance and endless variety. Because of scientific agriculture and food technology, Americans enjoy the safest, highest quality, most convenient, and—most amazing of all—cheapest food supply of any nation on earth. What is wrong with this picture?
   ... An issue to which the average American eater has given entirely too little attention is that of food security. Our economy, both national and global, is dependent at every point on lavish use of cheap, abundant, easily accessible fossil fuels. Nowhere is this dependence more obvious than in our industrial food systems: Agriculture is heavily dependent on energy-hungry machinery, chemical fertilizers made from natural gas, and pesticides made from petroleum. The excessive processing and packaging of most modern foods are energy and resource intensive. The average bite of food on the American table has been transported 1500 miles from field to fork.
   ...We do not see any goal, challenge, or problem in isolation, but seek to put into place broader patterns in which the same project or effort answers several needs. This article focuses on strategies the homesteader can adopt to achieve greater integration of the various elements in the homestead, leading not only to bountiful harvests of wholesome food, but to emergent synergies, more efficiency, and ever greater diversity and ecological health.


Why Our Food is So Dependent on Oil

"Concentrate on what cannot lie. The evidence..." -- Gil Grissom
   “Eating Oil” was the title of a book which was published in 1978 following the first oil crisis in 1973 (1). The aim of the book was to investigate the extent to which food supply in industrialised countries relied on fossil fuels. In the summer of 2000 the degree of dependence on oil in the UK food system was demonstrated once again when protestors blockaded oil refineries and fuel distribution depots. The fuel crises disrupted the distribution of food and industry leaders warned that their stores would be out of food within days. The lessons of 1973 have not been heeded.
   Today the food system is even more reliant on cheap crude oil. Virtually all of the processes in the modern food system are now dependent upon this finite resource, which is nearing its depletion phase. Moreover, at a time when we should be making massive cuts in the emissions of greenhouse gases into the atmosphere in order to reduce the threat posed by climate change, the food system is lengthening its supply chains and increasing emissions to the point where it is a significant contributor to global warming.
   The organic sector could be leading the development of a sustainable food system. Direct environmental and ecological impacts of agriculture ‘on the farm’ are certainly reduced in organic systems. However, global trade and distribution of organic products fritter away those benefits and undermine its leadership role. Not only is the contemporary food system inherently unsustainable, increasingly, it is damaging the environment.


The Food and Farming Transition

    The only way to avert a food crisis resulting from oil and natural gas price hikes and supply disruptions while also reversing agriculture’s contribution to climate change is to proactively and methodically remove fossil fuels from the food system. The removal of fossil fuels from the food system is inevitable: maintenance of the current system is simply not an option over the long term. Only the amount of time available for the transition process, and the strategies for pursuing it, can be matters for controversy. Given the degree to which the modern food system has become dependent on fossil fuels, many proposals for de-linking food and fuels are likely to appear radical. However, efforts toward this end must be judged not by the degree to which they preserve the status quo, but by their likely ability to solve the fundamental challenge that will face us: the need to feed a global population of 7 billion with a diminishing supply of fuels available to fertilize, plow, and irrigate fields and to harvest and transport crops.
   If this transition is undertaken proactively and intelligently, there could be many side benefits—more careers in farming, more protection for the environment, less soil erosion, a revitalization of rural culture, and more healthful food for everyone. Some of this transformation will inevitably be driven by market forces, led simply by the rising price of fossil fuels. However, without planning the transition may be wrenching and destructive, since market forces acting alone could bankrupt farmers while leaving consumers with few or no options.


Eating Fossil Fuels

   -- Human beings (like all other animals) draw their energy from the food they eat. Until the last century, all of the food energy available on this planet was derived from the sun through photosynthesis. Either you ate plants or you ate animals that fed on plants, but the energy in your food was ultimately derived from the sun...
   Solar energy is a renewable resource limited only by the inflow rate from the sun to the earth. Fossil fuels, on the other hand, are a stock-type resource that can be exploited at a nearly limitless rate. However, on a human timescale, fossil fuels are nonrenewable. They represent a planetary energy deposit which we can draw from at any rate we wish, but which will eventually be exhausted without renewal. The Green Revolution tapped into this energy deposit and used it to increase agricultural production...
   In a very real sense, we are literally eating fossil fuels. However, due to the laws of thermodynamics, there is not a direct correspondence between energy inflow and outflow in agriculture. Along the way, there is a marked energy loss. Between 1945 and 1994, energy input to agriculture increased 4-fold while crop yields only increased 3-fold.11 Since then, energy input has continued to increase without a corresponding increase in crop yield. We have reached the point of marginal returns. Yet, due to soil degradation, increased demands of pest management and increasing energy costs for irrigation (all of which is examined below), modern agriculture must continue increasing its energy expenditures simply to maintain current crop yields. The Green Revolution is becoming bankrupt. ..
   Quite plainly, as fossil fuel production begins to decline within the next decade, there will be less energy available for the production of food... Modern intensive agriculture is unsustainable.
   ...Given that the current U.S. population is in excess of 292 million, 40 that would mean a reduction of 92 million. To achieve a sustainable economy and avert disaster, the United States must reduce its population by at least one-third. The black plague during the 14th Century claimed approximately one-third of the European population (and more than half of the Asian and Indian populations), plunging the continent into a darkness from which it took them nearly two centuries to emerge.41
   None of this research considers the impact of declining fossil fuel production. The authors of all of these studies believe that the mentioned agricultural crisis will only begin to impact us after 2020, and will not become critical until 2050. The current peaking of global oil production (and subsequent decline of production), along with the peak of North American natural gas production will very likely precipitate this agricultural crisis much sooner than expected. Quite possibly, a U.S. population reduction of one-third will not be effective for sustainability; the necessary reduction might be in excess of one-half. And, for sustainability, global population will have to be reduced from the current 6.32 billion people42 to 2 billion-a reduction of 68% or over two-thirds. The end of this decade could see spiraling food prices without relief. And the coming decade could see massive starvation on a global level such as never experienced before by the human race.


Successful relocalization means that you stop growing...

   As relocalization efforts blossom globally, the discussions within local volunteer groups range from how to develop local food movements, alternative energy and conservation measures to climate change activities and the establishment of local currencies. Certainly such efforts reflect the need for these groups to maintain positive energies and attitudes by proactively engaging in project oriented activities that result in some visible outcome and are a building block for a positive future. Less common, although an underlying current in the foundational framework of most organizers and initiators, is the understanding that growth as we know it in all forms must cease.


The Future Of Food (1 of 2)
By Andrew Curry 14 February, 2011
http://www.countercurrents.org/curry140211.htm
   The recent UK Government Foresight report on the future of the global food and farming system can’t be faulted for a lack of ambition. It takes on the whole of the global food system, and looks out to 2050. Much of what it says is valuable (and the supporting papers look to be a useful research resource), and this is to be expected, given the calibre of the advisers the project was able to draw on. But there are some telling gaps, and these largely come from a lack of decent futures work in the report.


How Expensive Is Food, Really?
By Sharon Astyk 14 February, 2011

   This is a lightly revised and updated version of a piece that ran at ye olde blogge and at Grist, but it seems just as pertinent now as it did in 2007 when I wrote it. At the time, some people doubted that the boom we were seeing in biofuel production, which was pushing up grain prices, would be followed by any kind of a bust. Farmers were predicting many, many good years - but we all know what happened. Farm incomes dropped by more than 20% during the recession. Just another reminder that busts are part of the boom and bust cycle, no matter how little we like to admit it. There is no doubt whatsoever that rising food costs are hurting people all over the world. More than half of the world's population spends 50% of their income or more on food, and the massive rise in staple prices threatens to increase famine rates drastically. Many people have already pointed out the intersections between the changes going on across North Africa and the Middle East and the current food crisis, and with all of us having spent more time in food crisis than out of it in the last three years, that seems to be an emerging norm.
