Call to Action – BECOME AN ENDORSING ORGANIZATION TODAY

The industrial food system is a major contributor to global greenhouse gas emissions. Industrial agriculture practices, like Concentrated Animal Feeding Operations (CAFOs), large-scale monocultures, overuse and abuse of synthetic fertilizers and pesticides, fossil fuel intensive transportation and storage, all generate significant amounts of Greenhouse Gases (GHGs), not to mention underpin an inequitable and unhealthy food system.

Conversely, small-scale regenerative organic farming not only emits less greenhouse gases than industrial agriculture, including significantly less nitrous oxide and methane as compared to industrial agriculture, but has the potential to counter climate change by successfully sequestering carbon dioxide. Importantly, according to the United Nations Special Rapporteur on the Right to Food, small farmers hold the key to doubling food production while mitigating climate change and alleviating rural poverty. In fact, recent studies by the GRAIN demonstrate small farmers already feed the majority of the world with less than a quarter of all farmland. The Rodale Institute’s White Paper, “Regenerative Organic Agriculture and Climate Change,” states that small farmers and pastoralists could sequester more than 100% of current annual CO2 emissions with a switch to widely available, safe and inexpensive agroecological practices.

However, small-scale farmers and producers unfairly bear the brunt of climate impacts, threatening their communities and livelihoods. The Global South, although emitting only a fraction of all GHGs, disproportionately suffers the impacts of climate change, leading to environmental refugees, widespread hunger and economic injustice. For too long, only those who have been responsible for creating climate change have had a seat at the policy-making table; it is time to ensure those most affected and those most able to create solutions are heard.

While it is critical to continue to support efforts to develop a sensible and far-reaching strategy for renewable energy in both the government and marketplace, it is equally important to address one of the largest emitters of GHG and unjust sectors in the global economy, the industrial agriculture system. Addressing climate change on the farm and food system can not only tackle the challenging task of agriculture generated greenhouse gases, but produce more food with fewer fossil fuels, while building a just and sovereign food system.  Our communities, our economy, and our families demand immediate action.

Emerging Land Use Practices Rapidly Increase Soil Organic Matter

/by

Authors: Megan B. Machmuller, Marc Gerald Kramer, Kevin Taylor Cyle, Nick Hill, Dennis Hancock, Aaron Thompson

ABSTRACT

The loss of organic matter from agricultural lands constrains our ability to sustainably feed a growing population and mitigate the impacts of climate change. Addressing these challenges requires land use activities that accumulate soil carbon (C) while contributing to food production. In a region of extensive soil degradation in the southeastern United States, we evaluated soil C accumulation for 3 years across a 7-year chronosequence of three farms converted to management-intensive grazing. Here we show that these farms accumulated C at 8.0 Mg ha(-1) yr(-1), increasing cation exchange and water holding capacity by 95% and 34%, respectively. Thus, within a decade of management-intensive grazing practices soil C levels returned to those of native forest soils, and likely decreased fertilizer and irrigation demands. Emerging land uses, such as management-intensive grazing, may offer a rare win-win strategy combining profitable food production with rapid improvement of soil quality and short-term climate mitigation through soil C-accumulation.

Soil Carbon: Putting Carbon back where it belongs: In the earth

/by

Tony Lovell will explain the reasoning behind how more green growing plants means more captured carbon dioxide — more water — more production — more biodiversity — more profit. Did you know that a 1% change in soil organic matter across just one-quarter of the world’s land area could sequester 300 billion tonnes of physical CO2. TEDxDubbo focused attention on what we call FACETS — Food, Agriculture, Climate, Energy, Topsoil and Sustainability. These FACETS are actually potent ideas shared by everyday people with an interest in these disciplines. In many of these topics there is an awareness campaign; the aim of bringing our community together united against catastrophic failures in our food-chain, environment and health. It is worth mentioning that we are also indebted to our natural systems for our economic wealth. Failures in Food, Agriculture, Climate, Energy, Topsoil and Sustainability are not just a local issue — they are a global concern.

Peasant Agriculture is a True Solution to the Climate Crisis

/by

Climate disruptions this year have again caused widespread hunger, migration and the worsening of living conditions for millions of rural families, especially women and youth. While small farmers around the world continue to produce the food most people eat, glaciers are melting at an alarming rate, species of plants and animals are disappearing daily, islands and nations are being reclaimed by oceans, soils are eroding and forests igniting, and catastrophic events such as hurricanes, tornadoes, earthquakes and tsunamis are becoming commonplace. Meanwhile, the global food system imposed on people by Transnational Corporations (TNCs) is both a total failure and one of the main causes of the human-induced climate crisis – dependent on fossil fuels to produce, transform and transport, it is responsible for an estimated 44 to 57% of all global greenhouse emissions1. Instead of nutritious food for the world’s people, TNCs have produced hunger and obesity, land grabs and rural displacement, and a climate crisis they now hope to cash in on with false solutions sold at the United Nations.

Some twenty years since Rio (’92) and Kyoto (’97), governments have met over and over again for their Conference of the Parties (COP) to the UNFCCC (UN Framework Convention on Climate Change). They have continuously failed to protect and advance people’s most fundamental human rights – including the Right to Food – sending delegation upon delegation to climate talks that prioritize private interests over public welfare. Previous agreements and negotiations have moved from compulsory or binding accords to simple pledges that are not even likely to be kept. At the same time, TNCs have secured the political support of co-opted governments to get their interests inserted as bottom-line strategies into the agreements. Carbon markets, so-called “Clean Development Mechanisms” (CDMs), REDD and REDD+, bioenergy and agrofuels, as well as agribusiness’ proposed “climate-smart agriculture” package, are just a few of the misleading proposals now on the table. Instead of solving the problem, these false solutions only serve to worsen them. Instead of capping emissions, they create artificial markets and opportunities for the grossest of polluters to continue polluting and do little to reduce the effects of climate disruptions. By pushing the interests of capitalism and the privatization of nature, TNCs are putting the lives of ordinary people, small-scale farmers, peasants and indigenous communities – who work with nature to secure our livelihoods – into ever greater jeopardy.

Special Report: Cows Save the World

/by

Author: Allan Savory

I write to offer a constructive way forward in the tragic cultural genocide unfolding in America’s
wonderful western ranching culture that is embedded in the nation’s culture.
I do so knowing the risks of trying to help a lion by operating on a back molar in its jaw.

The recent RANGE article featuring Nevada rancher Cliven Bundy (whose cattle were taken from his southern Nevada range by the BLM backed up by SWAT teams) typifies the western ranching cultural genocide taking place. It is a tragedy based on deeply held myths and assumptions rather than on any known science.

No publication has done more than RANGE, valiantly fighting for fairness and the rights of ranchers in the protracted rancher-federal agency war over western public lands. When decent human beings—including ranchers, environmentalists and government land managers who are doing the best they can—all want healthy land with abundant wildlife, flowing rivers, stable rural families and communities in a healthy thriving nation, solutions and collaboration are needed instead of conflict.

How easy it is to draw our swords and yet how difficult it is to re-sheath them. So let me start with a point that I believe all parties can agree upon: management including policy should be based on science rather than on emotion, belief and assumption. With that in mind, let’s look at the current situation. Because the ultimate form of land degradation is man-made desert, I will use the official jargon and call the process rangeland desertification.

Desertification typically does not occur where precipitation and humidity are fairly well spread throughout the year, as in many coastal areas like Florida and Washington. However, most western rangelands experience long dry periods whether rainfall is high or low and here desertification occurs on both private and public lands. The symptoms of desertification are: increasingly frequent and severe droughts and floods, poverty, social breakdown, mass emigration to cities or across borders, decreasing wildlife, pastoral culture genocide, and violence and conflict. Most of these are being experienced in America today despite the good intentions of both ranchers and policy-makers.

Carbon Sequestration in Agricultural Soils

/by

The purpose of this report is to improve the knowledge base for facilitating investments in land management technologies that sequester soil organic carbon. While there are many studies on soil carbon sequestration, there is no single unifying volume that synthesizes knowledge on the impact of different land management practices on soil carbon sequestration rates across the world. A meta-analysis was carried out to provide soil carbon sequestration rates in Africa, Asia, and Latin America. This is one important element in decision-making for sustainable agricultural intensification, agro-ecosystems resilience, and comprehensive assessments of greenhouse mitigation potentials of Sustainable Land Management (SLM) practices. Furthermore, the ecosystem simulation modeling technique was used to predict future carbon storage in global cropland soils. Last, marginal abatement cost curves and trade-off graphs were used to assess the cost-effectiveness of the technologies in carbon sequestration. The remainder of the report is organized as follows. Chapter two provides a brief review of soil organic carbon dynamics and the methods for soil carbon assessment. The chapter concludes with brief information on carbon assessment in The World Bank’s sustainable land management projects portfolio. Chapter three reports the increase in soil carbon for selected sustainable land management practices in Africa, Asia, and Latin America. Chapter four reports the estimates from ecosystem simulation, while chapter five concludes with the benefits and costs of adopting carbon sequestering practices and a discussion of policy options to support climate smart agriculture in developing countries. The report will provide a broad perspective to natural resource managers and other professionals involved in scaling up Climate-Smart Agriculture (CSA).

Wake Up Before It Is Too Late: Make Agriculture Truly Sustainable Now for Food Security in a Changing Climate

/by

Developing and developed countries alike need a paradigm shift in agricultural development: from a “green revolution” to a “truly ecological intensification” approach. This implies a rapid and significant shift from conventional, monoculture-based and high external-input-dependent industrial production towards mosaics of sustainable, regenerative production systems that also considerably improve the productivity of small-scale farmers. We need to see a move from a linear to a holistic approach in agricultural management, which recognizes that a farmer is not only a producer of agricultural goods, but also a manager of an agro-ecological system that provides quite a number of public goods and services (e.g. water, soil, landscape, energy, biodiversity, and recreation) UNCTAD’s Trade and Environment Review 2013 (TER13) contends.

TER13 highlights that the required transformation is much more profound than simply tweaking the existing industrial agricultural system. Rather, what is called for is a better understanding of the multi-functionality of agriculture, its pivotal importance for pro-poor rural development and the significant role it can play in dealing with resource scarcities and in mitigating and adapting to climate change. However, the sheer scale at which modified production methods would have to be adopted, the significant governance issues, the power asymmetries’ problems in food input and output markets as well as the current trade rules for agriculture pose considerable challenges.

TER13, entitled Wake up Before it is Too Late: Make Agriculture Truly Sustainable Now for Food Security in a Changing Climate was released on 18 September 2013. More than 60 international experts have contributed their views to a comprehensive analysis of the challenges and the most suitable strategic approaches for dealing holistically with the inter-related problems of hunger and poverty, rural livelihoods, social and gender inequity, poor health and nutrition, and climate change and environmental sustainability – one of the most interesting and challenging subjects of present development discourse.

Agricultural development, the report underlines, is at a true crossroads. By way of illustration, food prices in the period 2011 to mid-2013 were almost 80% higher than for the period 2003-2008. Global fertilizer use increased by 8 times in the past 40 years, although global cereal production has scarcely doubled at the same time. The growth rates of agricultural productivity have recently declined from 2% to below 1% per annum. The two global environmental limits that have already been crossed (nitrogen contamination of soils and waters and biodiversity loss) were caused by agriculture. GHG emissions from agriculture are not only the single biggest source of global warming in the South, besides the transport sector, they are also the most dynamic. The scale of foreign land acquisitions (often also termed land grabbing) dwarfs the level of Official Development Assistance, the former being 5-10 times higher in value than the latter in recent years.

Regenerative Organic Agriculture and Climate Change: A Down to Earth Solution to Global Warming

/by

We are at the most critical moment in the history of our species, as man-made changes to the climate threaten humanity’s security on Earth. But there is a technology for massive planetary geo-engineering that is tried and tested and available for widespread dissemination right now. It costs little and is adaptable to local contexts the world over. It can be rolled out tomorrow providing multiple benefits beyond climate stabilization.

The solution is farming.

Simply put, we could sequester more than 100% of current annual CO2 emissions with a switch to widely available and inexpensive organic management practices, which we term “regenerative organic agriculture.”

Climate Change, Healthy Soils, and Holistic Grazing… A Restoration Story

/by

Author: Savory Institute

Summary

Regenerating the health and productivity of our soils is critical for ensuring the Earth’s climate remains conducive to not only human life but other species as well. Moreover, we need to take direct action so that we have enough water and food to sustain a growing population of people. Livestock, properly managed, have a critical role to play in achieving these goals.

Reducing fossil fuel emissions is essential for curtailing the acidification of our oceans and for reversing the rapidly increasing concentrations of carbon dioxide (CO2) and other greenhouse gases in the atmosphere. But it is just as critical that we greatly reduce the CO2 emissions tied to modern agricultural practices. In addition, there are still many billions of tons of CO2 in the atmosphere that need to be drawn down to Earth and safely stored if we are to maintain a livable climate for life on Earth.

The most obvious place to store this “legacy load” of CO2 is in our soils, where soil organisms convert it into organic matter, or soil organic carbon. The world’s soils, however, are unable to store the vast amounts of carbon they once did; scientists estimate our soils have lost up to 80 to 537 billion tons of carbon and that land misuse accounts for 30% of the carbon emissions entering the atmosphere.

Efforts to limit emissions from fossil fuel Combustion alone are incapable of stabilizing levels of carbon dioxide in the atmosphere.

Here we will shed light on the process of atmospheric carbon capture and storage that has developed in the natural world over millions of years, has minimal possibility for unintended consequences, and has myriad benefits for the health of lands worldwide as well as all dependent on them.

The quantity of carbon stored in soils is directly related to the diversity and health of soil life. Bacteria, fungi and other soil life convert carbon that plants have extracted from the atmosphere through photosynthesis into organic matter. When soils are healthy, soil life is healthy and more carbon is converted and stored.

The Solution Under Our Feet: How Regenerative Organic Agriculture Can Save the Planet

/by

Author: John W. Roulac

Many of us are now choosing to eat holistically grown foods. We want:

  • more nutrition from our food.
  • to avoid toxic pesticides and GMOs.
  • to create safer conditions for farmers and rural communities.
  • to protect the water, air and soil from contamination by toxic agrochemicals.

While these reasons are important, one critical issue is missing from today’s conversation about food. The concept is simple, yet virtually unknown. The solution to our global food and environmental crisis is literally under our feet.

If you take away only one thing from this article, I want it to be this quote from esteemed soil scientist Dr. Rattan Lal at Ohio State University:

NutivaLalCarbonQuote_1

Through the past hundred years, we’ve steadily increased our rate of digging up and burning carbon-rich matter for fuel. This is disturbing the oceanic ecosystem in profound ways that include reducing the plankton that feeds whales and provides oxygen for humans. And we’re not just talking about the extinction of whales. As I’ll detail in this article, even Maine lobsters could become a relic of the past.

We’ve severely disrupted the balance in the “carbon triad” by clearing rainforests, degrading farmland, denuding pasturelands, and burning coal and oil. The carbon triad? Yes; think of the three main carbon sinks: the atmosphere, the oceans and the humus-sphere. While I’m sure you’re familiar with the first two, you might not know about the latter carbon sink. Humus is the organic component of soil. (Gardeners create it as compost.) The humus-sphere is made up of the stable, long-lasting remnants of decaying organic material, essential to the Earth’s soil fertility and our ability to grow nutrient-rich crops.
