Agroecology Getting to the Root Causes of Climate Change

Food has not been the focus of climate change discussions as much as it should have been. (…)  We can still act and it won’t be too late”   Barack Obama, 26 May 2017.[1]

Of course, Barack Obama can speak more freely now that he’s not in the White House with the agribusiness lobby breathing down his neck. But he is right in that the climate–food connection has been largely absent from the climate discussions – at least in the official circles. This issue of Farming Matters focuses on this connection. It shows how the industrial food system is a main culprit when it comes to the climate crisis, and illustrates how agroecology and food sovereignty offer solutions by addressing the root causes of this crisis – political, social and environmental.

The latest studies calculate that the global food system – from farm to fork – is responsible for at least one third of all greenhouse gas emissions, a figure that seems to increase with the release of each new report. [2] GRAIN puts the figure closer to 50%, and stresses that it is the industrial food system which is mostly responsible for this. [3] Besides not feeding the people with enough healthy, culturally appropriate and sustainably produced food, the industrial food system is also leading us down the path of a global environmental crisis, of a scale and impact that humanity has never faced before.

Agriculture is supposed to be about turning the energy provided by the sun into food and fibre. But the corporate-driven global food system mostly relies on fossil energy: for chemical fertilizers and pesticides, mechanisation of the farm, pumping water for irrigation, etc.

Deforestation driven by ever expanding commodity crop plantations, soil erosion driven by unsustainable practices, transport, processing and freezing of food produced in places far away from where it is consumed, and the tremendous energy waste in the increasingly centralised corporate retail and supermarket systems aggravate the problem. Each of these emit huge amounts of greenhouse gases into the atmosphere.

Despite the obvious connection between the industrial food system and the climate crisis, and the obvious potential that agroecology and food sovereignty offer to turn the tide, these links are nowhere to be seen in any of the governmental climate negotiations. Instead, government officials seem to be betting on financial carbon markets and other corporate-driven ‘solutions’ that get us in deeper trouble. As Michel Pimbert explains, these false solutions include ‘Climate-smart Agriculture’ initiatives which merely conform to the dominant industrial food and farming system and are working against a truly transformative agroecology . REDD+, carbon markets and biofuel policies are additional examples of false solutions that work against agroecology and food sovereignty. In another article, GRAIN shows how industrial meat and dairy production is encouraging over consumption of meat with a disastrous impact on the climate and human health.

It doesn’t need to be this way. A radical shift towards food sovereignty would go a long way in solving the climate crisis: agroecological practices would massively build back organic matter (carbon) into the soils and largely eliminate the need for chemical fertilizers, and a focus on local markets and fresh produce would reduce the need for long distance transport, freezing and processing. Agrarian reforms aimed at supporting small scale food producers rather than promoting plantation farming would give back the land to those who produce food rather than those who produce commodities and help stop deforestation in the process.

Nurturing the soil, cooling the planet

The food–climate intersection is rooted in the earth. The expansion of unsustainable agricultural practices over the past century has led to the destruction of between 30-75% of the organic matter in soils on arable lands, and 50% of the organic matter on pastures and prairies. This massive loss of organic matter is responsible for a large part of the current CO2 excess in the earth’s atmosphere. But the good news is that the CO2 that we have sent into the atmosphere can be put back into the soil simply by restoring and supporting the practices that small farmers have been engaging in for generations. This has the potential to capture more than two thirds of the current excess CO2 in the atmosphere. [4]
