Over-consumption of food is bad for the planet and unhealthy for humans.
To help feed a growing world population, restore biodiversity and slow climate change, a geologist calls for a moon shot effort to restore healthy soil around the world.
The impact of plant disease may be reduced if people are made aware of the many pathways for plant-killing microbes -- and why preventing their spread matters to us all.
Conventional wisdom says we need industrial agriculture to feed the world. Not so, says geologist David Montgomery: Practices that focus on creating healthy soil can transform agriculture.
South Africa's social grants, which benefit a third of the country's population, are widely celebrated. But these grants fall far short of addressing the country's malnutrition challenge.
New technologies are developing with exponential velocity, breadth and depth. Their systemic impact is likely to be profound.
Urban consumers in Africa are rapidly growing and they are demanding high quality, pesticide free food.
According to widely-cited estimates, world food production must double by 2050 to keep up with population growth. New research challenges this target and calls for balancing growth with conservation.
At a time when poverty and hunger levels are declining around the world, famine is recurring, driven by conflicts and natural disasters. But timely action by governments and aid groups can save lives.
The main source of global warming isn't baking or transport, but fertiliser used to grow wheat.
Reflections on World Wetland Day on how this precious resource can be used sustainably to reduce rural poverty, improve food security and strengthen livelihood in the face of climate change.
Recycling leftovers from supermarkets does not address the roots of food poverty and removes responsibility from the government.
Coastal indigenous peoples consume nearly four times more seafood per capita than the world average and have strong cultural ties to the sea. Global ocean policies should preserve these connections.
Food, water and climate are complex, interconnected systems that when disrupted can cause severe social and political shocks.
Researchers are developing biological tools that can boost crop yields to feed a growing world population without harming human health or the environment.
Rich countries waste a lot of food. Producers and consumers need to rethink eating habits if this problem is to be solved.
Australia's wheat harvest has stalled over the past 26 years, and worsening weather is to blame.
Cassava is a key food source in tropical countries, but yields have been flat for decades. New genetic research is identifying many options for boosting production of this valuable staple crop.
Many people are suspicious of GM crops, but new techniques could massively increase food production.
How can we feed a growing world population while protecting the environment? One key strategy is to improve yields on small farms, which produce much of the food in the world's hungriest countries.
