Fertilizer trees boost yields in Africa

2011-10-16T17:35:00Z

Fertilizer trees—which fix nitrogen in the soil—have improved crops yields in five African countries, according to a new study in the International Journal of Agricultural Sustainability. In some cases yields have doubled with the simple addition of nitrogen-soaking trees. The research found that fertilizer trees could play a role in alleviating hunger on the continent while improving environmental conditions.

Five ways to feed billions without trashing the planet

2011-10-13T15:47:00Z

At the end of this month the UN predicts global population will hit 7 billion people, having doubled from 3.5 billion in less than 50 years. Yet even as the Earth hits this new milestone, one billion people do not have enough food; meanwhile the rapid expansion of agriculture is one of the leading causes of global environmental degradation, including greenhouse gas emissions, destruction of forests, marine pollution, mass extinction, water scarcity, and soil degradation. So, how do we feed the human population—which continues to rise and is expected to hit nine billion by 2050—while preserving the multitude of ecosystem services that support global food production? A new study in Nature proposes a five-point plan to this dilemma.

Organic farming can be more profitable in the long-term than conventional agriculture

2011-09-01T19:26:00Z

Organic farming is more profitable and economically secure than conventional farming even over the long-term, according to a new study in Agronomy Journal. Using experimental farm plots, researchers with the University of Minnesota found that organic beat conventional even if organic price premiums (i.e. customers willing to pay more for organic) were to drop as much as 50 percent.

Controversial study finds intensive farming partnered with strict protected areas is best for biodiversity

2011-09-01T17:56:00Z

Given that we have very likely entered an age of mass extinction—and human population continues to rise (not unrelated)—researchers are scrambling to determine the best methods to save the world's suffering species. In the midst of this debate, a new study in Science, which is bound to have detractors, has found that setting aside land for strict protection coupled with intensive farming is the best way to both preserve species and feed a growing human world. However, other researchers say the study is missing the point, both on global hunger and biodiversity.

Growing strawberries organically yields more nutritious fruit and healthier soil

2010-11-08T14:18:00Z

Strawberry plants grown on commercial organic farms yield higher-quality fruit and have healthier soil than those grown conventionally, according to a study published on 1 September in the journal PLoS One. The research suggests that sustainable farming practices can produce nutritious fruit, if farmers manage soil and its beneficial microbes properly. This is among the most comprehensive studies to investigate how conventional and organic farming methods affect both fruit and soil quality.

Farms in the sky, an interview with Dickson Despommier

2010-10-12T16:37:00Z

To solve today's environmental crises—climate change, deforestation, mass extinction, and marine degradation—while feeding a growing population (on its way to 9 billion) will require not only thinking outside the box, but a "new box altogether" according to Dr. Dickson Despommier, author of the new book, The Vertical Farm. Exciting policy-makers and environmentalists, Despommier's bold idea for skyscrapers devoted to agriculture is certainly thinking outside the box.

Could forest conservation payments undermine organic agriculture?

2010-09-07T16:41:00Z

Forest carbon payment programs like the proposed reducing emissions from deforestation and degradation (REDD) mechanism could put pressure on wildlife-friendly farming techniques by increasing the need to intensify agricultural production, warns a paper published this June in Conservation Biology. The paper, written by Jaboury Ghazoul and Lian Pin Koh of ETH Zurich and myself in September 2009, posits that by increasing the opportunity cost of conversion of forest land for agriculture, REDD will potentially constrain the amount of land available to meet growing demand for food. Because organic agriculture and other biodiversity-friendly farming practices generally have lower yields than industrial agriculture, REDD will therefore encourage a shift toward from more productive forms of food production.

Could agroforestry solve the biodiversity crisis and address poverty?, an interview with Shonil Bhagwat

2009-09-24T21:57:00Z

With the world facing a variety of crises: climate change, food shortages, extreme poverty, and biodiversity loss, researchers are looking at ways to address more than one issue at once by revolutionizing sectors of society. One of the ideas is a transformation of agricultural practices from intensive chemical-dependent crops to mixing agriculture and forest, while relying on organic methods. The latter is known as agroforestry or land sharing—balancing the crop yields with biodiversity. Shonil Bhagwat, Director of MSc in Biodiversity, Conservation and Management at the School of Geography and the Environment, Oxford, believes this philosophy could help the world tackle some of its biggest problems.

Sustainable farming is the only way to feed the planet going forward

2009-02-05T16:04:00Z

Embracing more sustainable farming methods is the only way for the world's farmers to grow enough food to meet the demands of a growing population and respond to climate change, the top crop expert with the United Nations Food and Agriculture Organization (FAO) said today.

Food miles are less important to environment than food choices, study concludes

2008-06-02T14:30:39Z

Shoppers concerned about the environment should not place "buying local" at the top of their list of priorities when purchasing food, according to a study published online on April 16 in the journal Environmental Science & Technology. The fuel burned in transporting food items from farm to marketplace creates just a small percentage of the total greenhouse gas emissions associated with the food. Instead, consumers should shift their diets to include more foods that require less energy to produce in the first place.
