What technologies could sustainably replace pesticides, without compromising on yield or quality? The Global Food Security (GFS) programme’s David O’Gorman reviews a recent GFS workshop on the topic.
What would happen if we could no longer use pesticides? Well, there would be significant yield losses, food price increases, greater food insecurity and potentially political unrest and instability. There may well be reduced ecological impacts, but with loss of yield would come expansion of agricultural land, with release of GHGs and loss of biodiversity.
We are heavily reliant on pesticides to maximise crop yields and put food on our tables. Even with the use of pesticides, a third of food (PDF) produced for human consumption is lost or wasted – what might the figure be with a dramatic increase in pre-harvest losses following reduced pesticide use?

Many had expected the 1.5°C temperature goal to drop out of the draft text during the fortnight of negotiations. Now, as the dust settles after the landmark agreement, scientists are grappling with the feasibility of meeting this more ambitious target.
But there was one sector that was largely absent from the talks in Paris. It’s something that we rely on everyday, and continuing to ignore it could mean waving goodbye to that 1.5°C goal. It’s food.

Insights from a public food distribution system in Odisha, by Manoj Kumar Pati of the Institute of Public Health, Bengaluru.
Today, India operates one of the largest food safety nets in the world.
To secure food and mitigate hunger and malnutrition for a country of 1.22Bn people – the world’s second largest population – is an immensely complex and challenging job. However, the Government of India’s recent effort to mitigate hunger with the National Food Security Act (NFSA) 2013 is truly commendable, while acknowledging that many more things need to be done and the initiatives have to be self-sustained for a considerable time.

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.

GFS Champion Tim Benton looks to the New Year and considers food waste on national and personal levels (including his own recipes).
I enjoy cooking, so do the kitchen duty when I am at home. And, of course, Christmas is the most intensive cooking festival. I just totted up that I prepared 141 meals, spread over 32 mealtimes. No wonder coming back to work seems restful!
As food waste is such an issue, we worked hard to minimise waste over the period through a concerted effort of planning, inventorying and negotiation over how to eat left overs. As a result, we threw away very little that was avoidable, perhaps though at the expense of over-consumption!

GFS Champion Tim Benton takes a personal look at weight gain and ruminates on what quantifies over consumption.
As many readers of this blog will appreciate, the demand for food is rising globally and many posts on this site tackle the issues associated with increasing production. The demand-side of the equation perhaps gets less attention than it deserves.
Like many people of middle age, I have gained weight in recent years. Yes, I know of many extenuating circumstances (= “excuses”) that have changed my daily energy budget, but the ineluctable truth is that I have piled on the best part of 10 kilos in the last decade.
