Plants have evolved techniques for protecting themselves from heat and insect attacks – but when both these stresses happen at once, one defense may neutralize the other.
Through genetic detective work, scientists have identified missing links in the tomato’s evolution from a wild blueberry-sized fruit in South America to the larger modern tomato of today.
Nigeria recently approved the world's first GM cowpea, which provides full protection against the pod-borer Maruca, a major problem for this important crop.
New research shows even brief hot spells can damage seed quality.
Most of the maize consumed in Kenya is never even tested for aflatoxin.
Combining and fermenting indigenous African grains can help counter malnutrition on the continent.
Certain wasps and flies which lay their eggs in specific species such as aphids could be a sustainable form of pest control.
Pesticides have become almost essential for agriculture, but their misuse can have negative effects on crops too.
It's unlikely that all species of bees will go extinct anytime soon – but current losses could still have a terrible impact on food supplies and ecosystems.
There are plenty of barriers, but if we really want to we can feed the world on plant protein (largely from legumes).
Indoor plant factories have high energy costs since LEDs replace the sunlight outdoor plants get for free. Scientists found a way to dial back how much light is needed by breaking it into tiny bursts.
As climate change alters temperature and rainfall patterns, yields of some crops are increasing while others decline. The net result: less food, especially where it's most needed.
We don't notice the plant species we're losing, but we won't be able to ignore the effect of their loss on our supply of food and medicine.
Combining and fermenting readily available indigenous African crops can help counter malnutrition on the continent.
Carbon in soil can help with tackling climate change. Maintaining soil quality by supporting farmers through economic incentives and technical approaches is important.
Biodiversity is in crisis. Nowhere is this more serious than among the wild species which our livestock and crops descend from.
Tasting like a smoky sundried tomato, the desert raisin has been a staple for Australian desert communities for thousands of years.
Governments need to think about global ways agricultural policies may affect the stability of the food system as a whole, beyond locally focused efforts to increase resilience in production.
Australian wheat growers need to boost yields to stay competitive in the face of climate change. They could do this by sowing earlier, but need new varieties of wheat to help them do it.
Predictions suggest that Africa will suffer dramatic losses of crops and productive land as the climate warms. Perhaps adopting GM crops designed to tolerate stress can save the continent from famine.
