A major new report spells out what science can, and can’t do to help provide nutritious food for all.
As readers of this blog will know, “Feeding the Planet” or ‘food security’ is hugely important. Food production involves more land, water and people than other areas of human endeavour. Access to food determines health and influences national security and patterns of human movement.
The breadth of the challenge
Research is hugely important for ensuring food security, but the challenges – and the research needs – are not simply about how to produce more food. The report groups the key research needs into seven inter-related themes, each of which is important for developing a sustainable agri-foodsystem. ( see figure 1).
In a sense, food security is a ‘meta-challenge’ as it seeks to provide sufficient safe, nutritious, food for a healthy life for all involves coping with climate change, competition for land and water and issues around trade, equity and access.
Research is necessary but not sufficient
Whilst research has a central role in creating new knowledge to tackle the challenges, it is part of the process not the whole. There is a virtuous cycle that strategic research should contribute to. First, a ‘look ahead’ horizon-scanning exercise should help set the research agenda. Research should then create the opportunities for social and technological innovation, which ultimately should lead to social and economic change. But in the meantime, as the world has changed, so perhaps have the key research questions, requiring a new round of horizon-scanning (see figure 2).
Each of these steps is important: research needs to create knowledge that can be used for innovations to address important questions of the time. Equally, innovations can rarely emerge without relying on fundamental research ‘upstream’ – understanding insect physiology is needed to develop pesticides, for example. In our time of austerity, where innovation is needed for economic growth, protecting the fundamental research budget is especially important, but especially at such times fundamental research can be seen as a luxury.
The challenges in figure 1 are so diverse and extensive, it is impossible for any one nation to address each fully within an affordable research base. This fundamental constraint then needs to drive two further considerations: how can different countries work together, through coordination and alignment, and therefore achieve the global outcomes we need?
By coordinating strategy and research prioritising, it is possible to identify common priorities, such as an aim to increase the efficiency of nutrient usage in agriculture. These common priorities can be addressed by creating joint or aligned research efforts to maximise the value of any research investment, and to ensure the money is spent fruitfully, irrespective of artificial geographic, institutional and disciplinary boundaries. The added value of alignment can arise by sharing ideas, sharing data or infrastructure. For example, the Global Food Security (GFS) programme is playing a role in leading an OECD-sponsored project ‘TempAg’ with an aim of linking researchers, research infrastructure and data across the temperate world to share ideas, approaches and allow much greater replication than a single country can provide.
Revving against the limits
Research clearly plays a central role in providing the raw material for innovation leading to social and economic change. However the institutional infrastructure to connect the researchers to the societal challenges on one side, and research knowledge to users on the other, also really matters. Research is of less value if the ‘wrong questions’ are answered, or research is not made full use of; so funders should fully coordinate fully along the innovation pathway to set the agenda and get research into use. This is something we are learning well in the UK, with the Agri-Tech strategy and GFS partner InnovateUK filling important roles connecting ‘upstream research’ and ‘downstream use’.
Our GFS programme is held up internationally as an exemplar of within-country coordination and alignment; we bring diverse public institutions together to complement, coordinate and align at many levels. GFS’s systems analyses not only shape the thinking of the GFS partners, but, as the Expo document indicates, are shaping the agenda more broadly. The challenge remains that complex systems often need to be divided into manageable chunks. But dividing creates divisions, and divisions create barriers. Interdisciplinary and transdisciplinary work is needed more than ever to cross such boundaries; and coordination between institutions here and across the world is needed to ensure each of us contributes our piece of the jigsaw to the global big picture.
