How Ecological Farming Builds Resilience to Climate Change

Last week, I joined a panel at the Global Agribusiness Forum in São Paolo (Brazil) to talk about the impacts of climate change on agriculture and food production.

You might be surprised that Greenpeace was at an agribusiness conference. The room was full of agri-business people, who are not the crowd we normally engage with; they are the crowd we normally challenge with our campaigns. However, I appreciated having the opportunity to be a dissenting voice and to talk about how ecological farming is a more resilient and sustainable model to produce diverse and healthy food in the face of erratic climate patterns.

The model of farming we choose can either make us more vulnerable, or help us both to be more resilient to our changing climate and to reduce greenhouse gas emissions. We cannot afford to endlessly discuss the effects of global climate change on agriculture and do nothing about it. In fact, the impacts of climate change—like massive droughts, typhoons and storms—are already appearing and are consistent with climate change scenario predictions. The time for debate is over. Now is the time to tackle the problem head-on with real solutions.

One approach—the one that many of the Global Agribusiness Forum attendees support—is continuing to expand the chemical-intensive industrial agriculture model. Yet, this model has already shown itself to be fundamentally flawed and unable to address the climate challenges the world is already experiencing. In fact, it firstly requires stable climates and optimal growing conditions for highly specialized seeds to achieve high yields. Second, the model relies on vast areas of monoculture (large scale planting of a single crop), which harm biodiversity. Third, this model is also dependent on expensive chemical products (pesticides and fertilizers), which lead to farmer indebtedness, heavily pollute the environment, damage natural biodiversity and are based on fossil fuels. The fossil fuel dependence, in particular, means that as fossil fuel prices rise, food prices rise, causing increased suffering for the world’s poor people.

A better approach to ensure food production under challenging climatic conditions is ecological farming, a system based on diversity of nature to produce food for all: the diversity of seeds and plants; the diversity of many different crops grown at the same time in the same field; the diversity of insects which pollinate (like bees) or eliminate pests; the diversity of farming systems mixing crops with livestock. The result is a diverse range of food that is healthy for both people and the planet.

A good example of how ecological farming builds resilience to climate change is growing crops with beans, which are protein-rich and flavorful, but also can help play a role in climate adaptation. Scientists from Wageningen University in the Netherlands recently found that beans greatly improve poor soils, increase productivity of maize when grown with them, and respond well to drought. They also have multiple uses for food, animal feed, and soil fertility. These scientists found that growing maize and beans next to each other increased income by 67 percent without the use of any chemical fertilizers and farmers were interested in adopting it.

All eyes are now on emerging economies—Brazil, China and India—who together produce and consume the majority of food on the planet. As the Intergovernmental Panel on Climate Change (IPCC) report, released today, points out, our food system is going to be impacted negatively, especially in these countries. It is very possible that climate change will bring the economic development of these crucial regions to a virtual standstill. However, this is not inevitable.

The solutions of ecological farming exist and can be built upon to create a new food future. And, Brazil has a strong ecological farming movement that has already succeeded in achieving a national policy on agroecology (the science of ecological farming). They can help to lead the way. But, alongside the ecological farming model, Brazil is investing heavily in expanding industrial agriculture. Thus, Brazil currently has two parallel models that can not co-exist together: one based on growing food with the diversity of nature, that is healthy for people and the planet; the other based on chemical-intensive monocultures to grow commodity crops for export that mostly feed animals. However, only by shifting financial resources to support widescale uptake of ecological farming will Brazil show global leadership and become a beacon of modern and innovative agriculture.

Other countries are looking to Brazil to share their experiences, especially those in Africa, a region desperately in need of a system that can not only sufficiently feed people but also face the most dramatic manifestations of climate change. As an African, I can tell you that Africa doesn’t need or want the chemical-intensive industrial agriculture model. What Africa wants is for Brazil to share its successes with ecological farming and show the entire world that ecological farming is indeed the only path to ensure healthy food for people, protect the environment and cope with climate change.

Brutal Outlook for Healthy Wild Horses and Burros: BLM Calls for Shooting 90,000

On Thursday, the National Wild Horse and Burro Advisory Board recklessly voted to approve recommendations that call on the Bureau of Land Management to shoot tens of thousands of healthy wild horses and burros.

At its meeting in Grand Junction, Colorado, the advisory board recommended that BLM achieve its on-range population goal of 26,715 wild horses and burros while also phasing out the use of long-term holding facilities—both within three years.

‘Geostorm’ Movie and Climate Hacking: Are the Dangers Real?

By Jane A. Flegal and Andrew Maynard

Hollywood's latest disaster flick, "Geostorm," is premised on the idea that humans have figured out how to control the earth's climate. A powerful satellite-based technology allows users to fine-tune the weather, overcoming the ravages of climate change. Everyone, everywhere can quite literally "have a nice day," until—spoiler alert!—things do not go as planned.

Admittedly, the movie is a fantasy set in a deeply unrealistic near-future. But coming on the heels of one of the most extreme hurricane seasons in recent history, it's tempting to imagine a world where we could regulate the weather.

GOP-Controlled Senate Paves Way for Oil Drilling in Alaska's Arctic National Wildlife Refuge

The Senate Republicans' narrow passage of the 2018 budget plan on Thursday opened the door for oil and gas drilling in the Arctic National Wildlife Reserve (ANWR).

But Democratic lawmakers and environmental groups criticized the GOP for sneaking the "backdoor drilling provision" through the budget process. Past proposals to drill in the refuge have consistently failed.

Corporate Fleets Making the Switch to Electric Vehicles

By Gina Coplon-Newfield and Sung-Jae Park

Recently, 10 major transnational corporations launched EV100, a new global initiative to slash emissions by increasing the number of corporate fleet electric vehicles (EV) on the road. EV100 companies, including Ikea, Unilever and HP, are committing to, by 2030, integrate EVs into their owned or leased fleets and install EV charging stations for customers and employees.

The full initial list of companies, many of which operate many thousands of fleet vehicles, includes: Baidu, Deutsche Post DHL Group, Heathrow Airport, HP Inc., IKEA Group, LeasePlan, METRO AG, PG&E, Unilever and Vattenfall. Vattenfall, the Swedish power company that serves most of Europe, intends to meet the campaign's commitments, and then some. "Replacing our whole 3,500 car fleet with EV in the coming five years, working with our customers to deploy charging infrastructure, and building northern Europe's biggest connected charging network, are three examples of actions we are taking to promote a sustainable and climate smarter living for customers and citizens," Magnus Hall, CEO of Vattenfall, said.

Puerto Rico's Revival Depends on Empowering Small-Scale Farmers

Reporting by Saulo Araujo

Houses without roofs and trees without leaves is all the eyes could see in the week following the devastation that Hurricane Maria wrought. The Category 5 storm with 150+ miles per hour winds was the strongest to hit the island in over a century, leaving the entire population without water and power. Weeks later 3 million people are still without electricity.

Up in the mountains, small-scale farmers lost their crops, and their ability to feed their families was abruptly leveled. La Organización Boricuá de Agricultura Ecológica (Boricuá) a grassroots organization of more than 100 families made up of small-scale farmers, farmworkers and organizers across Puerto Rico and the islands of Vieques & Culebra, continues working to communicate with their members in rural areas and to assess the damages. Boricua has made great progress in the last three decades to organize and support farmers, facilitate farmer-to-farmer trainings, and build solidarity nationally and globally. They are helping to fuel agroecology on the island, bringing locally grown, nutritious food to their communities and to market.

New EPA Climate Change Website Doesn't Mention 'Climate Change'

In the Trump administration's ongoing efforts to pretend that climate change doesn't exist, the U.S. Environmental Protection Agency (EPA) has made dramatic changes to a website catered to helping states, local and tribal governments learn about global warming and how prepare and respond to the impacts of our hot new world, according to a new analysis from the watchdog group Environmental Data and Governance Initiative (EDGI).

As you can see in the screenshot above, the website site was previously titled "Climate and Energy Resources for State, Local, and Tribal Governments." Now, it's called, "Energy Resources for State, Local, and Tribal Governments." Fifteen mentions of the term "climate change" were scrubbed from the original main page alone, and the old epa.gov/statelocalclimate URL even redirects to epa.gov/statelocalenergy.
