‘He who has bread may have troubles, He who lacks it has only one.’Old Byzantine proverb
Since 1950 the world’s population has almost tripled to 7.7 billion and until recently the relative abundance of food has kept pace, with the poorest benefiting the most. Over the years the so-called Green Revolution, despite …
Plant pests and diseases are significantly reducing yields of five major food crops across the globe, underscoring the critical need to develop new resistant varieties, according to a new study.
Some 137 pathogens and pests cause losses of 10 to 40 percent in the staple crops — wheat, maize (corn), soybeans, …
B4FA Fellow Michael Ssali reports:
Farmers always worry about possible loss of their crops due to pests and crop diseases. It is one of the reasons they keep monitoring their fields to ensure all is going on well. Fighting pests and crop diseases increases the farmers’ production costs and often reduces profits.
It …
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 …
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 …
The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) says it foresees rolling roll out new varieties of drought- and disease-resistant grains to African farmers next year to increase food security in the region. Read …
Mark Lynas writes:
Growing genetically modified insect-resistant corn in the United States has dramatically reduced insecticide use and created a “halo effect” that also benefits farmers raising non-GM and organic crops, new research shows.
This finding, published by University of Maryland researchers in the prestigious peer-reviewed journal Proceedings of the National Academy of Sciences, effectively …
Many Kenyan maize farmers are busy preparing their seed stock for the next planting season. Sowing high quality seeds of stress-tolerant varieties is a cost-effective way for African smallholder farmers to boost their harvests while being resilient to evolving crop pests and diseases as well as an erratic climate. However, even if a …
Why are South Africa and Sudan ahead of every other country on the continent when it comes to biotech? The answer is simple. The nations realized early on that they needed to embrace new technologies to develop faster maturing and better yielding disease-resistant and drought-tolerant crop varieties to counter a …
A new paper published on 8 January in Nature Communications describes a ‘precision-guided sterile insect technique’ that can effectively alter insect genes to control female viability and male fertility. The method could potentially be used to suppress increasing pest populations that threaten agricultural crops and to prevent the transmission of deadly diseases. The controllable, …
