The Courage to Embrace Radical Choices in the Face of the Climate and Food Crisis
One of the worst droughts in living memory continues to threaten East and Southern African countries, brought on by the recent El Nino event. More than 40 million people across the continent are projected to be food insecure until early 2017, as maize harvests wither and millions of livestock perish from lack of water and food.
One of the worst droughts in living memory continues to threaten East and Southern African countries, brought on by the recent El Nino event. More than 40 million people across the continent are projected to be food insecure until early 2017, as maize harvests wither and millions of livestock perish from lack of water and food.
Scientists expect more frequent and more intense droughts in a changing climate. As temperatures rise, soil moisture levels are depleted more quickly. As rainfall patterns change, farmers experience less frequent and/or more intense rains, leading to reduced or failed harvests. The current El Nino impacts give us a glimpse of the future under climate change, with greater variability in yields and greater vulnerability of food systems.
Regrettably, action on climate change has been too slow. Though countries have committed in the recently concluded Paris climate agreement to keep warming below a 2degC increase above pre-industrial global average temperatures, and to attempt to stay below 1.5degC of warming, the voluntary actions currently being taken by governments under that agreement put us on track globally for 3 or 3.5degC of warming. According to climate scientist Kevin Anderson of the Tyndall Center for Climate Change Research, that magnitude of temperature rise is "incompatible with an organized global community, is likely to be beyond 'adaptation', is devastating to the majority of ecosystems, and has a high probability of not being stable." For example, climate model predictions with that level of warming indicate long-term droughts and desertification settling in across most of Southern Africa.
"Nothing less than a fundamental transformation is required."
We ignore the urgency of climate action at our peril. While much of our attention on climate impacts is focused on hurricanes, cyclones, and the damage of storm surges, the creeping desiccation of many productive areas around the world poses grave risks to stable, let alone increasing, food production. The breadth and severity of impacts from the current El Nino are a realistic indication of what the future holds if we do not manage to quickly transition our economies away from fossil-fuel-based energy sources.
Action in the agriculture sector is also essential. Two strategies in particular are key.
First, we must decrease agriculture's contribution to the climate problem. Roughly 13% of global emissions come directly from agricultural production, in particular through industrial meat production and consumption and the production and use of synthetic mineral nitrogen fertilizers.
Beef and dairy are particularly problematic. Scientists have estimated that if we reduce meat consumption in the global North to the world's average--about 35 kg/year/person--we could cut in half the greenhouse emissions coming from the livestock sector.
If we switch from synthetic nitrogen sources--which require very high temperatures as well as natural gas as feedstock in their production, which alone contributes 1% of total global emissions annually--to organic sources of nitrogen fertilizer, we can further dramatically reduce emissions from the agriculture sector.
The other essential strategy is to build resilience in our farming systems. One way to do this is by paying attention to the health of our soils. By deliberately building soils with natural fertility-enhancing technologies--including manure, compost, and cover cropping--we can increase their fertility at the same time we increase their water-holding capacity. Soils can withstand longer dry periods and can absorb more rainwater in extreme precipitation events. For example farmers in Zambia, working with the Kasisi Agricultural Training Center, were able to increase their yields and soil moisture using agroecological practices, which led to an overall increase in household food security.
Another essential element of a resilience-building strategy is seed and crop diversity. By increasing the diversity in their fields, farmers create a buffer against variable weather and the changing climate. One year might be drier and the next wetter. Growing a range of crops, and different varieties of their staple crops, helps them continue to produce food even as conditions change. But to keep pace with changing climates, farmers not only need seeds, they need knowledge of successful climate adaptation practices, and networks to share knowledge and seeds. The Farmer-Scientist Partnership for Development--MASIPAG in its Philippine acronym --is a shining example of such a network: joining tens of thousands of farmers across the Philippines, working together with scientists, to share both knowledge and seeds better adapted to changing climatic conditions.
These low-cost agricultural technologies--of improved soil and water management and farmer-to-farmer networking and seed sharing--are elements of an agroecological approach to crop production, and will be essential components of our efforts to continue to produce food in the face of climate change.
The theme for this year's World Food Day is "Climate is changing. Food and agriculture must too." That fact is more than obvious. But we must critically ask the question: "But how?" Tinkering around the edges, engineering small tweaks in how we produce and consume food will not suffice. Nothing less than a fundamental transformation is required.
Urgent. It's never been this bad.
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission from the outset was simple. To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It’s never been this bad out there. And it’s never been this hard to keep us going. At the very moment Common Dreams is most needed and doing some of its best and most important work, the threats we face are intensifying. Right now, with just three days to go in our Spring Campaign, we're falling short of our make-or-break goal. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Can you make a gift right now to make sure Common Dreams not only survives but thrives? There is no backup plan or rainy day fund. There is only you. —Craig Brown, Co-founder |
