As armyworms return to devastate crops in Africa, Lancaster University’s Professor Ken Wilson reports on renewed efforts to bring a sustainable solution.
As we roll into 2017, my thoughts cast back to a whirlwind visit I made to Zambia at about the same time of year four years ago.
I witnessed a major outbreak of African armyworm caterpillars destroying the vital maize crops of local smallholder farmers and causing a country-wide food security crisis. As you can see in the video below, I met with the then Vice President of Zambia, Dr Guy Scott, and told him of our ongoing research, funded (PDF) by Global Food Security programme partners BBSRC and the UK’s Department for International Development (DfID) aimed at developing a locally-produced biological pesticide against this devastating plant pest.

Insect farms could recover the true value of wasted organic nutrients, improve local food security and assist in environmental protection, says Keiran Olivares Whitaker of Entocycle.
Agriculture is probably the single most damaging human activity for the planet. Natural resources are already stretched, and to feed the future growing population and meet the demographic shifts in diet, extreme environmental damage will occur.
The optimum direction would be for the global population to shift to a more plant-based diet. The trajectory however is for 70% increase (PDF) in fish and meat consumption by 2050. But around 70% of agricultural land and 70% of fresh water use is already designated to produce feed for animals (PDF), and a recent report from The Economist has highlighted nearly 100% of fish stocks are now under pressure, to varying degrees of severity.

In an audio slideshow special, food writer and consultant Geoff Tansey wonders what will happen to the ancient rice terraces of the Far East.
Will China build on its long-term sustainable farming systems, such as these famous rice terraces in Yunnan, or abandon them?
That’s the question I’ve found myself pondering about since my most recent visit to China.
As you can see in these pictures, for many visitors to China it’s the gleaming new city centres, glitzy shopping malls and swathes of high-rise apartments that seem to grow faster than their crops that impress.

At the launch of a new report on food security and climate change, the British Consulate in Chicago’s Jack Westwood is optimistic.
Having previously worked in a laboratory trying to find solutions to prevent and control the spread of crop disease, food security issues are often on my mind. However, being a scientist often means focusing on a very specific problem, so when the Chicago Council on Global Affairs (CCGA), an independent think-tank committed to educating the public and influencing policy debate, launched its latest report ‘Advancing Global Food Security in the Face of Changing Climate’ on May 22 in Washington DC, it put my previous work into sharp relief.

A natural virus could control devastating pest outbreaks and improve food security for thousands of farmers. In a special video diary, Ken Wilson reports on a long weekend in Zambia.
“We have arranged for you to meet the Vice President at 10am on Sunday. Is this OK?”. That was it, my trip to Zambia was definitely on and I had just a few hours to prepare for my field visit and meet one of the country’s top politicians who was leading their efforts to manage a food security crisis.
But as you can see in the video below (which you can also watch on YouTube, or in a shorter 03:50 video feature), this visit turned out to be rather different from the rest.
