We can save individual species — but can we save entire ecosystems?

The 1973 Endangered Species Act has rescued numerous individual species from extinction in the United States — think Rocky Mountain wolves or Florida crocodiles, for instance. But as the climate changes and humans continue to modify the landscape in a frenzy of plows, pastures and pavement, single species are not the only things in need of protection from extinction. Entire ecosystems — biological communities created through millions of years of evolutionary interactions between organisms — are at risk as well. Saving single species alone will not restore the intricate tapestry of relationships that shape ecosystems. To protect the habitat that supports those species and preserve services we humans rely on, from cleansing water for our cities and homes to buffering impacts of climate change, we need to save not just species, but also ecosystems, from extinction.

The concept of ecosystem extinction has been recognized for some time in the scientific literature, but is just now beginning to gain widespread application in land management. In fact, the International Union for Conservation of Nature — source of the Red List of Threatened Species, our planet’s premier “high alert” when species start going down the tubes — is developing a red list of endangered ecosystems, similar to its threatened species list.

Thanks largely to agriculture, tallgrass prairie has been reduced by 99 percent.

Among those most threatened are grasslands. Historically, these ecosystems served as valuable habitat for a spectrum of species and provided humans with natural plant- and animal-based foods, as well as wide-open spaces valued for aesthetics and recreation. Today the IUCN calls them “the most altered biome on the planet.” Tallgrass prairie, for example, once covered a Texas-sized swath of North America. From the Canadian Great Plains to the Oklahoman Panhandle, tallgrass prairie supported a diverse array of native plants, pollinating insects and large animals, from grizzlies to bison and elk. Thanks largely to agriculture, tallgrass prairie has been reduced by 99 percent down to a few slivers of road margins and sandy hills throughout the Midwest, now totaling an area smaller than Rhode Island.

Food at COP21: Three new initiatives spotlight food insecurity, soils, waste

It’s become a catch-22 of our times: the global food system is both a villain and a victim of climate change. Agriculture accounts for almost a quarter of global greenhouse gas emissions, and yet floods, drought, and the planet’s increasing climatic variability play with the fate of our food. Continuing on the current climate trajectory will mean a future of profound food insecurity, especially for developing nations.

This week, these concerns have been prominent on the agenda at the COP21 climate talks in Paris. For the first time at a COP conference, agriculture had its own dedicated focus-day, held on Tuesday by the Lima-Paris Action Agenda (LPAA), a partnership established between France and Peru to showcase and strengthen on-the-ground climate action in 2015 and beyond. “For years, agriculture, food systems, including oceans, including forests, have been knocking hard at the door—and now there’s movement starting,” said David Nabarro, former special representative of food security and nutrition for the United Nations, at the LPAA agriculture press briefing on Tuesday afternoon.

That door should have been yanked open a long time ago, considering that our food systems are due to bear so much of the brunt of climate change. But there are strong signs of progress. The world needs creative solutions if we are to reduce agricultural impact and feed everyone on the planet (an estimated nine billion by 2050)—and some of the best have recently been aired at the talks.

Here are three that caught my eye: each places our global food system squarely on the climate table.

Keeping soil carbon on lockdown

The planet’s soils naturally hold vast quantities of carbon—two to three times more carbon than the air. Releasing it through unsuitable, soil-degrading agricultural techniques will contribute to climate change and also reduce soil health—but, if we keep more carbon locked in the soil, it has the power to both mitigate climate change and increase agricultural productivity.

On Tuesday as part of the Lima-Paris Action Agenda, hundreds of partners joined to launch ‘4/1000’, an initiative designed to increase the storage of carbon in the earth: “If we were to increase the amount of carbon in the soil by just 0.4% then we would compensate entirely for the increase of carbon in the atmosphere—just to show how huge the potential is,” says Frank Rijsberman, CEO of the CGIAR Consortium of International Agricultural Centers, one of the partners contributing to the initiative. As part of 4/1000 the CGIAR itself is proposing a $225 million project that aims to increase carbon storage by promoting better farming techniques in developing world agriculture. Methods like agroforestry and reduced soil tillage could keep carbon enclosed in the soil, leading to a 20 percent boost in yields, and in theory offsetting greenhouse gas emissions by 15 percent. The benefits will be three-pronged, says Rijsberman: “We will mitigate greenhouse gas emissions; adapt agriculture to climate change and thus improve food security; and improve ecosystem functioning.”

Soils for food security and the climate

/by

Thanks to plants and living organisms, soils contain two to three times more carbon than the atmosphere.  Carbon-rich soil organic matter is essential: it retains the water, nitrogen and phosphorus that are indispensable to agriculture. But alternating phases of drought and intense rainfall accentuate erosive phenomena.  In the long term, almost 30 million hectares of arable land could be lost every ten years.

The solution: carbon storage

If the carbon stocks in the top 40 centimetres of soil could be increased by 4 per 1000 each year, this could theoretically help to stop the current rise in the quantity of CO2 in the atmosphere, on condition that deforestation is halted.

The methods: 5 ways to develop soil management and agroecology

  1. Avoid leaving the soil bare in order to limit carbon losses
  2. Restore degraded crops, grasslands and forests
  3. Plant trees and legumes which fix atmospheric nitrogen in the soil
  4. Feed the soil with manure and composts
  5. Conserve and collect water at the feet of plants to favour plant growth

Applied to the surface horizon of the world’s soils, or a stock of around 860 billion tonnes of carbon, the 4‰ target would result in the annual storage of 3.4 billion tonnes of soil carbon, thus counterbalancing the rise in atmospheric CO2. This measure would be extended beyond agricultural soils to most soils and their uses, including forests.

570 million farms in the world and more than 3 billion people living in rural areas could implement these practices.

The cost for crops, 20 to 40 USD per tonne of CO2. For grasslands and forests, 50 or 80 USD per tonne of CO2. Carbon would continue to accumulate in soils for twenty to thirty years after the introduction of good practices, if they are sustained.

On World Soil Day, OCA, IFOAM Laud French Government’s Initiative to Address Climate Change via Carbon Sequestration in Organic Soil

December 5 marks end of International Year of the Soils, beginning of work to replace degenerative industrial ag with organic regenerative strategies that can reverse global warming

PARIS – As the International Year of the Soils officially ended on December 5, World Soil Day, Organic Consumers Association (OCA) and IFOAM Organics International (IFOAM) praised the French Government’s 4 per 1000 Initiative as the most important climate strategy to come out of the COP21 Paris Climate Talks.

“This is the most exciting news to come out of COP21,” said Andre Leu, president of IFOAM Organics International. “By launching this Initiative, the French Government has validated the work of scientists and farmers and ranchers who have demonstrated the power of organic regenerative agriculture to restore the soil’s natural ability to draw down and sequester carbon.

“It is imperative that world the decarbonizes the atmosphere from 400 ppm to far less than 350 ppm to stop catastrophic climate change. The combination of renewable energy to stop further emissions and drawing down excess CO2 into the soil is most achievable way to do this and it is readily available to us now.”

“What better way to celebrate World Soil Day than to recognize that healthy soil is our most available, most promising solution to global warming,” said Ronnie Cummins, OCA’s international director. “As we celebrate this important Initiative and also mark the end of the International Year of the Soils, we look forward to what is arguably the most important work our organizations and our governments face—reversing global warming before it’s too late.”

OCA and IFOAM Organics International are among the 100 partners who were signed on at the launch of the “4 per 1000” Initiative. Partners include developed and developing states, international organizations, private foundations, international funds, NGOs and farmers’ organizations.

The partners have agreed to reinforce their actions on appropriate soil management, recognizing the importance of soil health for the transition towards productive, highly resilient agriculture.

The “4/1000 Initiative: Soils for Food Security and Climate” aims to protect and increase carbon stocks in soils.  According to the French Agriculture Ministry, a 0.4-percent annual growth rate in soil carbon content would make it possible to stop the present increase in atmospheric CO2 and achieve the long-term objective of limiting the average global temperature increase to the 1.5°C to 2°C threshold beyond which the Intergovernmental Panel on Climate Change (IPCC) says would lead to a climate disaster.

The initiative consists of a voluntary action plan under the Lima-Paris Action Agenda (LPAA), backed by an ambitious research program.

The United Nations officially declared 2015 the International Year of the Soils, beginning on December 5, 2014, and ending on World Soil Day, December 5, 2015. The official closure took place at FAO headquarters on December 4.

IFOAM – Organics International is the worldwide umbrella organization for the organic agriculture movement, which represents close to 800 member organizations  in about 125 countries.

The Organic Consumers Association (OCA) is an online and grassroots non-profit 501(c)(3) public interest organization representing 2 million U.S. consumers campaigning for health, justice, and sustainability. The Organic Consumers Fund is a 501(c)4 allied organization of the Organic Consumers Association, focused on grassroots lobbying and legislative action.

IFOAM – Organics International has joined the “4 per 1000” Initiative (link is external), which aims to improve the organic matter content and promote carbon sequestration in soils through the application of agricultural practices adapted to local situations both economically, environmentally and socially, such as agro-ecology, agroforestry, conservation agriculture and landscape management.

The official launch of the initiative took place 01 December 2015 at the COP21 Climate Conference with keynote speeches given by Tabaré  Aguerre,  Minister for livestock, Agriculture and Fisheries of Uruguay as well as Christian Schmidt, Minister for Food and Agriculture of Germany.

Both José Graziano Da Silva, Director-general of FAO and Stéphane  Le Foll, Minister for Agriculture, Food Processing Industry and Forestry of France agreed that farmers need more access to knowledge in order to farm successfully with better soil management practices.

Commenting on the event, Gábor Figeczky, Advocacy Manager at IFOAM – Organics International was pleased to note that Agroecology is at the heart of the “4 per 1000” Initiative. Read more about the initiative.
