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.

Delivering more sustainable food and farming has to start with reconnecting people with where their food comes from and how it is produced, says LEAF’s Annabel Shackleton.
With 81.5% of the UK population (PDF) living in urban areas, our connection with the natural world, farming and the value of our food is increasingly being lost.
With this in mind, how do we make long lasting and meaningful changes to the way people think about and engage with their food? How do we embed health as a value when we make food choices? And how can we link consumer knowledge and demands to deliver more sustainable food and farming?

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.

Can we tap into ecological defences to better protect crops? The University of Sheffield’s Will Buswell reports.
Crop pathogens are a substantial drain on world food production. Annually, an estimated 20% of global yields are lost to disease, but this figure belies far greater losses for specific food systems and the people whose stable existence is dependent upon them, particularly in developing countries.
For instance, rice is the staple crop for over half of the world’s population, yet almost 40% of yield is lost to disease each year.

What innovations really have the potential to transform the food-producing landscape? Head of the Global Food Security programme Riaz Bhunnoo takes a whistle-stop tour.
In just a 35 year period the Earth is being tasked with producing more food than it has in the last 2000 years combined. We either need to find very clever ways of sustainably producing more on the same area of land, or we need to demand less. In reality we need to do both, and cutting-edge technologies will have a key role to play.

Employing exotic animals and plants can help the fight against hunger and power economic development. UJAT’s Mike Mitchell reports.
Is there more that can be done with so-called ‘invasive’ species?
The introduction of ‘alien’ or ‘non-native’ species varies greatly around the world and through history. From stowaway rodents on cargo ships rodents, seeds or pollen clung to clothing or deliberately introduced as with Japanese knotweed, to pets released to unexpectedly thrive in the wild like lionfish, they are usually considered pests or weeds in their new homes.

A new network helps researchers get their hands dirty. The Soil Association’s Tom MacMillan explains how you can get involved.
What would agricultural R&D look like if farmers were in charge?
I’ve written for this blog before about the Duchy Future Farming Programme, which recognises and supports innovation by farmers. With three years of ‘field labs’ under our belts, involving more than 750 farmers and looking into 35 topics, we’ve just launched its next phase – a network called Innovative Farmers.

An expert group gathers to discuss this elemental problem. The John Innes Centre’s Allan Downie reports on problems and progress.
What is the nitrogen crisis? It is clear that we have introduced major global shifts in production and use of reactive nitrogen without really knowing what happens to the ammonia and nitrogen oxides released to the environment.
The production of nitrogen fertiliser and combustion of fossil fuels doubles the amount of reactive N entering the nitrogen cycle annually.

Training female farmers to get the best from their land can reap benefits. IFDC’s former president Amit Roy makes the case for fertilisers and other innovations.
By 2030, the agriculture and agribusiness sector in Africa is predicted to become a US $1 trillion industry. Farming has long been hailed as the engine of the African economy, and over the next 15 years it is going to need a jump-start if it is to feed the rocketing population, particularly in urban areas. Many factors will fuel this growth, but fertilizer is going to be critical.
Currently, 65 percent of land in Africa is degraded and lacking in the essential nutrients crops need to grow. Yet much of the world’s remaining arable land is in Africa. Replenishing undernourished soils is a unique opportunity for African agricultural growth.

Peter Gregory from the University of Reading and Richard McDowell, Principal Scientist at AgResearch, introduce the new GFS-coordinated TempAg network.
The International Sustainable Temperate Agriculture (TempAg) Network was launched in April 2015 as an international research network that aims to deliver sustainable agricultural systems in temperate regions of the world. After four years of preparatory work, we are delighted that our international research programme is now underway and linking scientists in the temperate regions of the world.
