San Francisco – Within hours of former Iowa Gov. Tom Vilsack’s nomination last week as Agriculture secretary, websites were humming with well-documented critiques of his affinity for genetically engineered crops, agribusiness giant Monsanto, heavily polluting factory farms, and other Big Farm interests.

Some critics expressed outrage, others surprise, especially since they had mounted a vigorous, 55,000-plus strong online petition to persuade President-elect Barack Obama to nominate someone more progressive who would promote sustainable food and farming.

The need for sweeping change could not be clearer when it comes to our food: At taxpayer expense, current policy subsidizes large corporate farms and destructive industrial agriculture, which rob the countryside of economic diversity and precious environmental resources, such as water and topsoil.

These same subsidies, and anemic regulatory enforcement, encourage an increasingly monopolized food system, and a “cheap food” policy that lards us with fatty, processed foods – the cost of which is ultimately dear, more than $100 billion annually for obesity and diet-related diseases. Today’s food system also generates a sizable portion of America’s greenhouse gases, and rests on fast-dwindling and volatile oil supplies.

Now is the time for something different – change we can eat.

As Mr. Obama weighs a massive stimulus package, he should include new funding streams that promote sustainable food – to build up alternatives such as farmer’s markets, local “foodshed” programs that promote consumption of local produce, and farm-to-institution projects that encourage schools, hospitals, and other large buyers to purchase local organic foods when possible.

The change we need in food is as urgent as any we face – changes that affect national health, energy security, global warming, and more. Here, then, is a not-so-modest nine-point platform for food reform, some of which could be included in Obama’s stimulus package. Other elements may require a lengthier policy push:

1. New public investments targeting sustainable agriculture, defined as organic, small- to mid-sized, diversified farming.

2. New investments in local/regional food networks and foodsheds – to help build up the connections between farmers and consumers, to open up and expand new markets for organic farmers and those considering the transition; for more farmer’s markets and food stores that feature local produce.

3. A moratorium on agribusiness mergers, and strenuous antitrust provisions and enforcement to protect what little is left of diversity in the food economy.

4. A moratorium on all new genetically modified (GMO) products, and an expansion of existing ones, and appointment of a blue-ribbon panel/commission to assess the impact of GMO foods on our environment and our health.

5. A moratorium on – and gradual phasing out of – concentrated animal feeding operations, aka factory farms, which are among the nation’s top polluters of water and air, and breeders of widespread and virulent bacterial strains.

6. Dramatically expanded regulatory enforcement and staffing in the US Department of Agriculture and the Food and Drug Administration to protect food safety and meat industry labor and environmental practices.

7. Slowing the hazardously fast meatpacking (and poultry) assembly line, to protect workers and consumers.

8. Incentives for small-scale urban, suburban, and rural farming ventures oriented toward diversified local food systems.

9. Bold public investment in a raft of public awareness campaigns that build support, and expand markets and demand, for sustainable alternatives such as urban agriculture and gardening, and reducing fast-food consumption.

Food is a vital cornerstone of both individual life and civil society, and our current system is making us fatter, churning out greenhouse gases, and abusing workers and animals.

With a new administration elected on a “change” agenda, it’s a timely moment to press for the most basic change of all: change in the food that ends up on our plates and in our bodies.
