Can we fix our failing food systems? Agroecology has answers

Can we fix our failing food systems? Agroecology has answers

  • The U.S. has an industrialized and unsustainable food system that depletes non-renewable resources such as groundwater and soil, and this model has been exported widely around the world, a top agriculture author explains on this episode of the Mongabay Newscast.
  • Two regions where these impacts and depletion are being felt most are in California’s Central Valley and on America’s Great Plains.
  • Consistent overproduction of commodities such as soy, milk and corn under an agribusiness model that pursues constant profits despite a local lack of demand exacerbates the problem, says Johns Hopkins Center for a Livable Future research associate Tom Philpott.
  • An author and former food journalist for Mother Jones and Grist, Philpott joins the podcast to talk about these acute problems and what can be done to reform unsustainable food systems with practices like agroecology.

Overproduction of cash crops, vast monocultures of chemical-dependent grains and massive animal agriculture operations are putting major stress not just on U.S. farmland — where they’re contributing to soil erosion, groundwater depletion and climate change — but these practices are also impacting areas such as the Brazilian Cerrado, where more than half the huge savanna has been converted to soy. Compounding these issues is the fact that roughly a third of all food produced in the U.S. is wasted, a statistic that also bears out globally.

As the 2023 growing season begins in the Northern Hemisphere, author and food journalist Tom Philpott — whose most recent book, “Perilous Bounty: The Looming Collapse of American Farming and How We Can Prevent It,” details these problems — joins the Mongabay Newscast to talk about the most problematic practices, how they permeate the world’s food systems and how techniques like agroecology and agroforestry could change the game and provide a way out.

Agroecology is a sustainable agriculture practice based on Indigenous and traditional methods of growing food that can address most of the aforementioned challenges while slowing the biodiversity crisis, according to the IPCC’s 2022 report. Its methods can increase the nutrient profile of soils, protect it from erosion and provide a more diversified set of crops for farmers to sell.

The question is, why don’t we do it? Philpott, who nowadays dives into these topics as a research associate for the Johns Hopkins Center for a Livable Future, says quarterly profits are the reason the U.S. focuses on the overproduction of cash crops, such as California’s almond farms, which he calls an “ecological catastrophe.” Ultimately, diversifying the crops we produce and incorporating practices such as agroforestry is the most promising solution, he says.

Additionally, addressing the colonial history of U.S. food production is something Philpott says he supports, and sees progress with movements such as LANDBACK and Black Agrarianism.

However, he says policy shifts are also needed and could come via the agricultural reform bills introduced to Congress by U.S. Senator Cory Booker. The passage of these would be steps in the right direction for reforming some of the most unsustainable practices and protecting fragile biodiversity, he says.

“We don’t have to have an agriculture that consumes the very ecologies that make it possible and leads to this catastrophic loss of species that we’re in the middle of right now,” says Philpott.
