African farmers want GMO seeds to help weather climate change

March 18th, 2019 / Genetic Literacy Project, US

It’s an old proverb in these lands that since man has learned to shoot without missing, birds have learned to fly without perching — and the same is true with farmers in Sub-Saharan Africa (SSA).

As climate change becomes more of a reality, bringing uneven seasons, longer droughts and heavy rains …

Using genetic engineering to turn annual crops into perennials could bolster global food production

March 18th, 2019 / Genetic Literacy Project, US

The last several decades have witnessed a remarkable increase in crop yields — doubling major grain crops since the 1950s. But a significant part of the world still suffers from malnutrition, and these gains in grains and other crops probably won’t be enough to feed a growing global population.

These facts …

How genetic engineering can help Africa cope with climate change by tweaking crops, animals

March 3rd, 2019 / Genetic Literacy Project, US

Climate change will have a dramatic impact on agricultural production in Africa.  Over the last century, temperatures across the continent increased by around 0.5 degrees Centigrade. If this trend continues as expected, extreme heat waves and droughts are likely to become more common. Climate estimates suggest that there could be an …

Why do we need to keep breeding new crop varieties?

February 26th, 2019 / Sustainable, Secure Food Blog

Global warming and changes in the amount – and location – of water, are key factors in the need to continue crop breeding programs. In addition, there are many diseases that affect crop yield and quality. We need to continue breeding new disease resistant crop varieties to ensure a healthy, …

New crop loss study underscores urgent need for resistant varieties

February 25th, 2019 / Alliance for Science, US

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, …

Growing threat to food from decline in biodiversity

February 25th, 2019 / BBC, UK

The plants, animals, and micro-organisms that are the bedrock of food production are in decline, according to a UN study.

If these critical species are lost, the report says, it “places the future of our food system under severe threat”.

The study says that land-use changes, pollution, and climate change are all …

Seeking the new potato

February 14th, 2019 / Science, US

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 …

Environment in multiple crises – report

February 12th, 2019 / BBC, UK

Politicians and policymakers have failed to grasp the gravity of the environmental crisis facing the Earth, a report claims.

The think-tank IPPR says human impacts have reached a critical stage and threaten to destabilise society and the global economy.

Scientists warn of a potentially deadly combination of factors.

These include climate change, mass …

Researchers develop disease-resistant climate-smart grains to help eradicate poverty in Africa

January 29th, 2019 / Bakeryandsnacks.com

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 …

To predict droughts, don’t look at the skies. Look in the soil… from space

January 29th, 2019 / The Conversation

Scientists and governments alike have been looking for ways to measure drought in a way that relates more closely to its impacts. Any farmer or gardener can tell you that you don’t need much rain, but you do need it at the right time. This is where the soil becomes …
