A four-minute documentary video on evolutionary plant breeding, a technique that can help farmers develop plant varieties that thrive in local conditions. In the video, Italian plant geneticist Salvatore Ceccarelli explains how the technique could help farmers around the world respond to problems posed by climate change and gain autonomy. Over …
Food security for all is a cornerstone of the United Nations 2030 Agenda, which recognizes that global sustainable development can only be achieved if hunger and all forms of malnutrition are eradicated (Sustainable Development Goal number 2). Nevertheless, the international community must be aware that food security does not only …
Genetically engineered (GE) crops producing insecticidal proteins from Bacillus thuringiensis (Bt) (mainly Cry proteins) have become a major control tactic for a number of key lepidopteran and coleopteran pests, mainly in maize, cotton, and soybean. As with any management tactic, there is concern that using GE crops might cause adverse effects on …
On a bleak, brown hill here, David Ellis examines a test plot of potato plants and shakes his head. “They’re dead, dead, dead,” he says. Pests and lack of rain have laid waste to all 17 varieties that researchers had planted.
It is a worrying sign for Ellis, the now-retired director …
An international team of researchers, including scientists affiliated with the USDA, have genetically modified cassava to contain much higher levels of iron and zinc than the non-transgenic variety. They used two genes from thale cress (Arabidopsis thaliana), a pathetic looking plant that happens to be one of the most studied …
Biodiversity along the food chain helps to maintain the air we breathe and the water we drink. Yet today, the world’s biodiversity is undergoing a crisis not seen since the extinction of the dinosaurs.
In just the past year, several studies show we are losing insects along the food chain at an alarming …
Climatic change has made issue of food insecurity more critical and serious in developing countries. According to Food and Agriculture Organization (FAO) of United Nations about 815 million people out of the 7.6 billion people in the world were suffering from chronic undernourishment in 2016. Most of these people belonged …
The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.
More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of …
Until very recently if you wanted to create, say, a drought-resistant corn plant, your options were extremely limited. You could opt for selective breeding, try bombarding seeds with radiation in the hope of inducing a favourable change, or else opt to insert a snippet of DNA from another organism entirely.
But …
