In 2050, the Paris Agreement will be 34 years old, Google will be 52, the National Park Service will be 134, the tractor will be 158, the United States will be 274, and hopefully we’ll all be celebrating being well along the way to a cooler future. While it may seem like a lot of time, there’s a lot of work ahead of us.
That’s why leaders around the world have been working in the aftermath of the Paris Agreement to develop strategies to reduce net global warming emissions to established goals by mid-century (2050). As it turns out, an important part of this work has to do with boosting food, farms, and farmers—and that’s what I’ll talk about. However, if you’d like to learn about other solutions, check out the posts by my colleagues on biofuels, forests, and the energy sector.
There is growing awareness of the value of the so-called “land carbon sink”. What is this all about? Well, plants and soils store carbon, keeping it out of the atmosphere. The more carbon can be “sequestered” into leaves, roots, stems tree trunks, and soils each year, the bigger the carbon “sink” and the smaller the climate change problem. Currently, about 762 million Mt CO2e worth of carbon are stored in plants and soils in the US. This is significant—enough to offset 11% of emissions— but insufficient given the magnitude of the climate change problem. Not only that, but since storing more carbon in lands also means building and protecting healthier soils, an investment in soil health simply makes sense. Luckily, the USDA already has a plan to help farms and forests sequester or offset an extra 120 million Mt CO2e/y (by 2025). This plan is a step in the right direction, but we can do better.

When it comes to climate change, the problem and the solution may be one and the same.
This week in Marrakesh, government leaders will meet for the last leg of the UN Climate Change Summit (COP 22) and it is clear we are at a critical moment in our history. Man-made changes to the climate threaten humanity’s security on Earth. Though we are taking steps globally to reduce emissions from industry, transportation and heat production, another source accounts for 24 percent of total global greenhouse gas emissions, according to the EPA.
That problem is farming.
Agriculture is the largest-single contributor to the climate crisis. The UN’s 2013 Trade and Environment Review points to agriculture as responsible for 43-57 percent of human-generated greenhouse gas emissions. The current degenerative farming system results in the loss of 50-75 percent of cultivated soils’ original carbon content. By destroying soil nutrients through the overuse of chemical fertilizers and pesticides, conventional agriculture jeopardizes food security and nutrition, and reduces ecosystems’ resiliency to flood and drought by removing the protective buffer provided by soil’s organic carbon.
Industrial agriculture is additionally responsible for large-scale degradation through factory farming, waste lagoons, antibiotics and growth hormones, GMOs, monocultures, and prolific use of chemical pesticides and fertilizers. But there is a biological process for reversing this damage and providing climate stabilization that’s tried and tested, available for widespread dissemination now, costs little and is locally adaptable.
That solution is farming.

Carbon dioxide is bad—it causes global warming. Carbon dioxide is political—U.S. democrats want regulations to reduce emissions into the atmosphere and republicans, led by president-elect Donald Trump, want to scrap such rules. But William McDonough says all that is wrong. “Carbon is not the enemy,” he said in a keynote speech at the recent SXSW Eco conference. The same phrase headlines his new commentary published today in Nature. “It is we who have made carbon toxic,” he writes. “In the right place, carbon is a resource and a tool.”
McDonough, founder of William McDonough + Partners, is a world-renowned architect, designer and urban planner. He has spearheaded several design movements—reflected in titles of his bestselling books such as Cradle to Cradle, and The Upcycle—as well as the idea of a circular economy. They all champion smarter ways to design products, buildings and communities to use resources more sustainably, generate less waste and create positive impacts rather than just minimize negative ones.
His latest point is that citizens and their politicians have to change the conversation about carbon. Climate change, he maintains, is a design failure, a breakdown in the natural carbon cycle caused by humans. By rethinking how we design things, especially cities, we can restore the natural carbon cycle and exploit it for human gain, creating positive environmental impacts rather than harm.
He claims that the focus of carbon regulation is also out of whack. “Striving for less pollution means we will do less bad,” he noted at SXSW Eco. “Instead we should ask, what can we do that creates more good?”

The role organic agriculture can play in fighting climate change effects and in boosting food security was the main theme of a debate held in the COP22 Green Zone by the federation of Moroccan organic agriculture professionals (known by its French acronym FIMABIO.)
Speaking on this occasion, Andre Leu, President of the International Federation of Organic Agriculture Movements (IFOAM), underscored that organic agriculture can reverse climate change.
He highlighted the global momentum towards adopting organic agriculture to counter climate change, notably through the “4 for 1000” initiative, which aims to increase the amount of organic matter in soil by 4 per thousand (0.4%) each year, which would be enough to compensate for all global greenhouse gases emitted due to human behavior.
Organic agriculture practices are conducive to the global efforts to reduce greenhouse gas emissions before the point of no return, he said.

Rosie Burroughs is worried about the pines. Each time she drives from her family’s dairy to their pack station in the Minarets, she notices more and more dead trees, the lush green landscape withering into a brown, twiggy boneyard. The Forest Service tells her the pines have been wiped out by a beetle that would normally die off in the cold season, but because the winters have been so mild, the beetle has proliferated, meaning devastation for the trees.
This is disconcerting not only for the forest, but also because the snow melt in the Sierra Nevada Mountains is a major source of California’s water. An ecological imbalance in the Sierras could portend disaster for the entire state.
Burroughs has noticed other changes too, at her family’s farms and at her neighbors’. Warm winters are confusing the plants, which bud and bloom out of season. Farmers who purchase water face skyrocketing prices. Others neighbors have had their water cut off before their crops could ripen.
For the agriculture industry, the effects of climate change have become undeniable, especially in the drought-prone state of California. Farmers, whose livelihoods are utterly dependent upon the cycles of nature, are on the front lines of the battle, taking the first and hardest blows. So while others may anxiously await for yet undiscovered technologies to thwart climate change, organic farmers are already adapting. Better yet, they are creating solutions that we can use immediately.

COP21, the global climate conference in Paris last year, resulted in an agreement on cutting atmospheric carbon. Now, COP22, which starts today in Marrakech, Morocco, will focus on how the world will adapt to climate change and mitigate its effects, especially in developing countries. The meeting is expected to have a greater focus on agriculture, and specifically on Africa.
In Paris, agricultural solutions—notably soil’s role as a carbon sink—entered global climate discussions. The chief vehicle was the French-led 4-per-1,000 Initiative, a pledge to increase carbon stocks in agricultural soils by 0.4 percent a year, a rate that proponents said would stem the rise of atmospheric carbon. The objective, says the French Ministry of Agriculture, “is to show that agriculture is part of the solution. It aims to increase organic carbon storage in soils, with a goal of improving food security and mitigating and adapting to climate change.”
Four-per-1,000 has more than 170 signatories, including 32 countries. The U.S. has not publicly supported it, instead aligning with the Global Alliance for Climate-Smart Agriculture, which is more oriented toward industry and includes biotechnology as one approach.
A new initiative, Adaption of African Agriculture (AAA), would place agriculture at the heart of climate talks. At a September meeting, a coalition of 27 African nations adopted the “Marrakesh Declaration,” which calls attention to the continent’s vulnerability to climate irregularities—such as the drought that has left 30 million southern Africans food insecure—and the risks borne by smallholder farmers.

Experts have forecast that a quarter of the carbon found in soil in France could be lost to the atmosphere during the next 100 years. This could lead to soil becoming a net source of carbon dioxide to the atmosphere. At present soil is considered to absorb carbon dioxide and this partially counters the impact of human-made climate change.
The pace and nature of predicted changes in climate over the next century will make the soil less able to store carbon, while business-as-usual land use change has limited capacity to counteract this trend, experts from the University of Exeter, INRA and CERFACS in France and University of Leuven in Belgium say in the journal Scientific Reports.
If, as predicted, soils lose a significant amount of their carbon this will endanger their ability to produce food and store water and this could lead to increased soil erosion and flood damage.

Recent reports from the Intergovernmental Panel on Climate Change (IPCC) suggest that even if substantial reductions in anthropogenic carbon emissions are achieved in the near future, efforts to sequester previously emitted carbon will be necessary to ensure safe levels of atmospheric carbon and to mitigate climate change (Smith et al. 2014). Research on sequestration has focused primarily on Carbon Capture and Storage (CCS) and reforestation with less attention to the role of soils as carbon sinks. Recent news reports of melting glaciers and ice sheets coupled with a decade of record-breaking heat underscores the importance of aggressive exploration of all possible sequestration strategies.
Soils have the potential to sequester carbon from the atmosphere with proper management. Based on global estimates of historic carbon stocks and projections of rising emissions, soil’s usefulness as a carbon sink and drawdown solution appear essential (Lal, 2004, 2008). Since over one third of arable land is in agriculture globally (World Bank, 2015a), finding ways to increase soil carbon in agricultural systems will be a major component of using soils as a sink. A number of agricultural management strategies appear to sequester soil carbon by increasing carbon inputs to the soil and enhancing various soil processes that protect carbon from microbial turnover. Uncertainties about the extent and permanence of carbon sequestration in these systems do still remain, but existing evidence is sufficient to warrant a greater global focus on agricultural soils as a potential climate stability wedge and drawdown solution. Furthermore, the ancillary benefits of increasing soil carbon, including improvements to soil structure, fertility, and water-holding capacity, outweigh potential costs. In this paper, we’ll discuss the basics of soil carbon, how it can be sequestered, management strategies that appear to show promise, and the debate about the potential of agricultural soils to be a climate stability wedge.

Prince Charles urged governments, individuals and businesses to take greater care of the world’s soils as part of an initiative aimed at keeping carbon locked in soil, rather than escaping into the atmosphere and causing global warming.
The “4 per 1000” project is a pledge to reduce the amount of carbon leaked from soils by 0.4% a year, which would be enough to halt the rise of carbon dioxide levels in the air. Nearly 180 countries have signed up to the initiative that was set up by the French government as part of its efforts to make the Paris agreement on climate change, signed last year, a success.
At a ceremony this week to celebrate the initiative, the prince said that the preservation of farmland, forests and soils were of “absolutely critical importance – for, in my experience, the fertility and health of the soil is at the heart of everything”. Drawing on his own work as an organic farmer, he contrasted organic methods with the “previously conventional” farming systems which he called “toxic”.
The 4 per 1000 initiative does not require farmers to adopt organic methods, but does encourage more attention to farming techniques, which are currently contributing to the erosion of soils around the world.
