Sustainable Farming

The BBC News website has an excellent feature on the upcoming resource crunch. The main story gives an overview:

...the warning from John Beddington, the UK government's chief scientific adviser, of a possible crisis in 2030. Specifically, he points to research indicating that by 2030 "a whole series of events come together":

• The world's population will rise by 33%
• Demand for food will increase by 50%
• Demand for water will increase by 30%
• Demand for energy will increase by 50%

He foresees each problem combining to create a "perfect storm" in which the whole is bigger, and more serious, than the sum of its parts.

As far as I can see, that's doesn't include the impact of the lost environmental services due to natural resource degradation and climate change. Considering these aspects, I think we'll face serious crises sooner, especially in the high-population density developing world.

There are accompanying articles with video on the three big aspects of the problem:

• Mega Cities and population growth (Delhi and Mumbai)
  
• Growing demand for resource (China)
• Deteriorating natural resources (Water shortages in California)
  

as well as on possible solutions:

• The changes in life style required
  
• The role of science
• The new agricultural trends and the case for more GM food
  

We have of course survived the previous Malthusian predictions, but this time it might be different:

Since the late 1980s, we have been in overshoot - the Ecological Footprint has exceeded the Earth’s biocapacity - by about 25%. Effectively, the Earth’s regenerative capacity can no longer keep up with demand – people are turning resources into waste faster than nature can turn waste back into resources.

The June issue of National Geographic* has a special report on the future of the global food system -

In an era of tightening supplies and rising prices, our hot and hungry world could face a perpetual food crisis.

The article is an excellent review of the previous "Green Revolution", its positive and negative consequences**, and the enormous challenges we face finding a better future for humans and other species through the twin challenges of global warming and population growth:

...is a reprise of the green revolution—with the traditional package of synthetic fertilizers, pesticides, and irrigation, supercharged by genetically engineered seeds—really the answer to the world's food crisis? Last year a massive study called the "International Assessment of Agricultural Knowledge, Science and Technology for Development" concluded that the immense production increases brought about by science and technology in the past 30 years have failed to improve food access for many of the world's poor. The six-year study, initiated by the World Bank and the UN's Food and Agriculture Organization and involving some 400 agricultural experts from around the globe, called for a paradigm shift in agriculture toward more sustainable and ecologically friendly practices that would benefit the world's 900 million small farmers, not just agribusiness.***
...
And so a shift has already begun to small, underfunded projects scattered across Africa and Asia. Some call it agroecology, others sustainable agriculture, but the underlying idea is revolutionary: that we must stop focusing on simply maximizing grain yields at any cost and consider the environmental and social impacts of food production. Vandana Shiva is a nuclear physicist turned agroecologist who is India's harshest critic of the green revolution. "I call it monocultures of the mind," she says. "They just look at yields of wheat and rice, but overall the food basket is going down. There were 250 kinds of crops in Punjab before the green revolution." Shiva argues that small-scale, biologically diverse farms can produce more food with fewer petroleum-based inputs. Her research has shown that using compost instead of natural-gas-derived fertilizer increases organic matter in the soil, sequestering carbon and holding moisture—two key advantages for farmers facing climate change. "If you are talking about solving the food crisis, these are the methods you need," adds Shiva.

Attention Conservation Notice:
A rapid education about life, consciousness, and society, as well as a thorough discussion of the problems we face in corporate institutions, globalization, and food and resource supply. This book has something for everyone, and everything for someone. Recommended.

Overview:
Written by Fritjof Capra, (The Tao of Physics, The Turning Point, etc.), and published first in 2002, The Hidden Connections is a very thorough and convincing overview of the change we need to create in this world if we want humanity to survive and thrive for the next thousand years.

Part one is a rapid (and fairly dense) information download about the processes and evolution of life, cognition and consciousness, and sociology, especially with respect to the patterns and processes common to these three levels of organization. Capra then wants to apply the understanding of these patterns and processes in part two to solve problems facing big corporations, global capitalism, and biotechnology.

Part two, however, is mainly a review of the state of thing in these three arenas, the important current events, and what other people have thought and written about these. While link between parts one and two is somewhat tenuous, (both in terms of the application of the patterns to solving the global problems as well as in the writing style) the chapters in part two themselves link together very well, and explore the very important issues of global finance, and the inequality it has generated, as well as agricultural biotechnology, which is endangering biodiversity and sustainability of farming world over.

All in all, the book is an excellent overview of some of the major problems we face in the world today, and how we can solve them. Be sure to read it.

We hear over and over again that industrial agriculture is the only way to feed the growing global population and end world hunger. What's the truth?

There is no shortage of food:

...enough food is grown worldwide to provide 4.3 pounds of food per person per day, which would include two and a half pounds of grain, beans, and nuts, a pound of fruits and vegetables, and nearly another pound of meat, milk, and eggs.

Why do 800 million people go hungry every day?

Industrial system has ... [forced] subsistence peasants off the land, so that it can be used for growing high priced export crops. ... the new 'landless' then flock to the newly industrialized cities where they quickly become a class of urban poor ... Their access to food is solely by purchase. Very often, they simply do not have enough money to buy food, so they starve.

Global corporations favor luxury, high-profit items:

As export crops and livestock use up available land, small farmers are forced to use marginal, less fertile lands. Staple food production for local use plummets, and hunger increases. ... during industrial agriculture's prime years (1970-90) the number of hungry people in every country except China actually increased by more than 11 percent.

What's the solution?

We need a major shift in efforts to feed the world, where the focus is on supporting local agriculture, where people live close to (or on) land, grow food to feed their own communities, and use ecologically sustainable techniques. In other words, hunger can only be solved by an agricultural system that promotes food independence.

Learning a lot of things and connecting with some very good like minded people at the PDC. Here's something I found out a few days ago:

The Environmental Food Crisis: The Environment's Role in Averting Future Food Crises was released by the United Nations Environment Programme in February 2009. A short summary is in this press release, the whole report is available for download here (15 MB pdf).

Some highlights:

The natural environment comprises the entire basis for food production through water, nutrients, soils, climate, weather and insects for pollination and controlling infestations. Land degradation, urban expansion and conversion of crops and cropland for non-food production, such as biofuels, may reduce the required cropland by 8–20% by 2050, if not compensated for in other ways.
...
Food prices may increase 30 to 50 per cent within decades, forcing those living in extreme poverty to spend 90 per cent of their income on food.
...
Over 80% of all endangered birds and mammals are threatened by unsustainable land use and agricultural expansion.

The report recommends seven strategies to tackle this crisis:

1. Regulate food prices and provide safety nets for the impoverished;
2. Promote environmentally sustainable higher-generation biofuels that does not compete for cropland and water resources;
3. Reallocate cereals used in animal feed to human consumption by developing alternative feeds based on new technology, waste and discards;
4. Support small-scale farmers by a global fund for micro-finance in developing diversified and resilient ecoagriculture and intercropping systems;
5. Increase trade and market access by improving infrastructure, reducing trade barriers, enhancing government subsidies and safety nets, as well as reducing armed conflict and corruption;
6. Limit global warming; and,
7. Raise awareness of the pressures of increasing population growth and consumption patterns on ecosystems.

D V Sridharan is one of modern India's heroes. A retired merchant navy officer, Mr. Sridharan started the website GoodNewsIndia.com in 2000, reporting on numerous grass roots efforts in India. Having covered a wide variety of philanthropic projects, he came to this interesting realization:

My stories were about two broad types. One set of projects was conceived from the beginning to become self-sustaining, which I shall call SS-projects. Holistic land based, environmentally sound projects were of this type. The other type usually served a humanitarian need and required steady inflow of funds. As they seemed to constantly fight a fire instead of ever able to douse it, I shall call them fire fighting or FF-projects. Orphanages, special education centres and gender issues are typical FF-projects.
...
...SS-projects were almost always rooted in caring for resources like water and soil. FF-projects were invariably funded by foreign donors; the corollary being, Indians are not very forthcoming in supporting charitable initiatives. Several of the FF-projects became addicted to seeking money and became notoriously unprofessional in terms of accounting for the funds received and the manner of their use.

By 2006 Mr. Sridharan decided that he needed to do more than just report on good efforts. This resulted in the beginning of project pointReturn to regenerate a "waste-land" and establish a self reliant community on it. He soon started posting regular updates about the logistics of pointReturn. The whole saga is definitely worth reading for anyone who is considering landscape restoration projects.

Along with describing the logistics, Mr. Sridharan continues to write insightful observations and commentary, for example in the articles India, browning, Gandhigram, an interlude, and A spell of inaction.

From 'A spell of inaction':

Deep in its collective heart, India’s political establishment believes rapid industrialisation is the goal to aim for; that an open door trade and investment policy in every economic activity is the way to get there; that income inequalities will be evened out by prosperity trickling down; that the numerous special economic zones created, -often on agricultural lands- will generate jobs and sustained properity; that India in the long run must come to have no more than 5% of its population in agriculture and that until that ideal balance comes about the only thing to do is to manage the inevitable social churning. Policy makers’ further tenets are that unending supply of industrial grade power must be assured for high standards of living; that such a living will create demand for products and services to keep the economy growing; that rising world trade will make all products available everywhere; that all food can be grown by mechanisation and engineered crops or freely imported from global markets;that the environmental costs of modern production processes are inevitable, over estimated and in any case, can be ‘fixed’ with the surpluses that a booming economy will produce.
...
The urban world is formally well informed about inflation, climate change, stock and commodity exchanges,the nation’s budget, recession etc but it can escape the negative effects of these in the shorter term because of the cash in its pockets. Rural India on the other hand, has no formal knowledge of these but directly experiences them- consequences of unseasonal rains and rising costs of farm inputs for instance hit them almost immediately. The remaining question is whether rural India can survive these in the longer term. The answer would be yes, for it is closer to the neglected earth. But the yes is a qualified one. The malign neglect of farming must stop, convictions must grow that natural farming -as against chemical farming- can be profitable.

P. Sainath has been a clear and rational voice for India's rural poor, farmers, and lower cast population, . He was awarded the Ramon Magsaysay Award (considered Asia's Nobel Prize) for Journalism in 2007 (as well as many other awards). His numerous articles (including a series of articles on farmer's suicides) provide an illuminating and sobering overview of issues including small and medium farming, inequities in global trade, government corruption and inaction, etc.

For a quick overview of the issues he has covered, read this interview conducted after he won the Magsaysay award:

...
Q: One hears a lot of people arguing that small and medium farms are simply unviable in the global agricultural scenario. Do you agree? Is there really a model that can work for the small farmer in India, or are we going to see family farms go the way they did in the US?

A: First off, I think they're wrong to question viability in such simplistic terms. If you consciously develop something, and nurture it, then it becomes viable. What we have is a situation where agriculture in India is being made unviable by imposition. Is American agriculture really viable? You have a situation where cotton crop worth 3.9 billion dollars receives 4.7 billion in subsidies. The Europeans are throwing billions of euros worth of crops into the sea. Whose farming is really unviable? In reality, developed world farming is hugely wasteful, not to forget destructive of soils. And yet, the question is asked if Third World farming, especially small and medium farms, can last in the long run.
...

We need to move away from environmentally and socially destructive industrial agriculture, and the only way to do that is to nurture high output small agriculture by reducing the high input costs and the market distorting subsidies in the developed world.

Eliminating small farmers' dependence on big-industry inputs, including on all fertilizers, pesticides and machines will prove to be the critical issue of the next few decades.
