Terrestrial and aquatic food production systems share a range of common problems that need solutions. Rachel Norman from the University of Stirling reports.
A mathematical biologist by training, I was very keen to tease out whether we could treat fish and crops as being the same when we come to think about problems in food security.
After some consternation amongst my biological colleagues, there was consensus that aquaculture systems share some common features with both crops and chickens – they both have relatively high stocking densities, for example. They also share common risks, for example disease outbreaks can be devastating in all cases.

The word ‘nexus’ seems to be cropping up everywhere, but what does it mean for food security? Global Food Security Champion Tim Benton explains.
Following Christmas, often an annual festival of demand and excess, maybe January is the time to think about demand-management. At the end of last year, I was involved in a flurry of meetings with the term ’nexus ‘ in the title. Nexus essentially means interconnectedness, or binding together.

What agricultural problems do Africa and Europe have in common? Jenny Wilson from UKCDS examines an ambitious collaborative project.
There’s a really exciting initiative that UKCDS (UK Collaborative on Development Sciences) has been involved in that aims to produce a step-change in the funding, and consequent research, available for EU-Africa scientific collaboration.

Did we really run over our fields at random in 30 ton farming vehicles? Agri-consultant Tim Chamen wants to stop it happening now.
Speak to any experienced garden vegetable grower about the acceptability of running a car over their vegetable plot and I guess they would look at you in horror!
And yet this is what farmers worldwide have done with their machines for many years because of the difficulty of doing otherwise. As the drive for improved production efficiency has risen together with labour costs (PDF, 41pp), farm machines have increased dramatically in size and crucially in weight.

Population growth and more meat-intensive diets require an increase in global protein production. NERC’s Jodie Clarke tucks into the issue.
According to the Food and Agriculture Organization’s (FAO) agricultural outlook for 2015-2030
total world meat production will continue to increase in this period by 1.5% per year while milk production is estimated to increase at 1.3% annually.
How can fish-producing technology scale up to feed more people? GFS science writer Theresa Meacham casts the net wide.
Having just launched the latest GFS Insight about Aquaculture (PDF), I have been thinking a lot about the role that fish have in our food system. For a start, in the UK we sell most of the fish we catch and eat imported fish mostly caught abroad!
Aquaculture production has increased at an average rate of 8.9% since 1970 in the UK. But in fact our industry is tiny compared to Asian production which is 89% of the global total. Some of the drivers behind this growth (despite exquisite taste!) have been the health benefits associated with eating fish and shellfish products, environmental pressures on land and wild fisheries as well as an increasing world population.

How can young agricultural entrepreneurs make the most of the continent’s opportunities? Sir Gordon Conway of Agriculture for Impact reports on the Montpellier Panel’s latest report.
The time has come to debunk a common myth about agriculture. It is not a dead-end profession that requires eternal, back breaking labour on a farm. At least, it does not have to be. With the right investments to support entrepreneurs in agriculture beyond the production stage, in processing, retail, marketing and even business management, profitable careers await Africa’s young population.

If 2014 is truly to be Africa’s Year of Agriculture and Food Security, then Africa’s production potential has to be addressed, says IFA Vice President for Africa Alassane Diallo.
Africa has awoken. Ten of the world’s fastest growing economies are now in Africa, with around one third of our 54 countries seeing annual GDP growth of over 6%.
However, this momentum has not yet spread to all sectors. Cereal crop yields in Africa are only one-third as high as in developing Asia, and only one-tenth as high as the United States. When one in five Africans still goes to bed hungry – how can this sector be ignored?

It’s not enough to sing their praises: let’s work on legal rights, market access, community-based support, and more equitable households say Melinda Fones Sundell and Marion Davis.
If you know anything about agriculture in sub-Saharan Africa, you know that women grow the majority of food crops. In Ghana, for example, women produce 70% of the nation’s food crops, provide 52% of the agricultural labour force, and contribute 95% of the labour for agro-processing activities. Across the region, 62.5% of women work in agriculture, compared with 36.4% globally (report p.57, A8).
Yet women farmers often work under very difficult conditions. Many don’t even control the land on which they grow their families’ food, and their access to fertilizers, tools, equipment and other inputs is also constrained. The UN Food and Agriculture Organization has estimated that if women had access to the same productive resources as men, they could increase their farm yields by 20-30%.

Christmas is traditionally a time of celebrating via food. GFS Champion Tim Benton explores the question of whether we should be more self-sufficient in producing it.
One of the questions asked in Westminster is “should the UK be more self-sufficient in food production?” According to government (PDF) data about 62% of our food is produced in Great Britain.
Last August, 62% of the way through the year, the National Farmers’ Union had a Back British Farming campaign pointing out that were there no international trade our “larder would be bare” from August onwards – definitely a problem for the Christmas feast then – and so growing more food locally would be benefit our food security by increasing self-sufficiency.
