Abstract:
To meet the increasing global demand for food that is predicted over the coming decades it will be necessary to increase productivity and to do this in a way that is sustainable and efficient in its use of resources. Productivity is currently determined by the intrinsic genetic potential of the domestic plants and animals on which mankind is dependent as well as by components of the biophysical environment (temperature, water availability and quality, soil fertility, parasites, pathogens, weeds) from which terrestrial or aquatic food production is derived. Within certain limits, it is possible to manipulate plant and animal genotypes, the production environment, and the inevitable interaction between these factors, to relax constraints on productivity and potential output. Looking to the future, increased scientific understanding will undoubtedly permit this manipulation to be achieved more effectively, thus enabling the scale of production to be elevated predictably while reducing reliance on non-renewable inputs and limiting the use of more forest, grassland, wetland or coastal margin. The present paper introduces a collection of reviews that were commissioned as part of the UK's Government Office of Science Foresight Project on Global Food and Farming Futures which reports early in 2011. The reviews explore opportunities for advances in science and technology to impact in coming decades on the sustainable productivity of terrestrial and aquatic food production systems. Collectively, they describe many of the approaches currently being considered to define, remove or relax the different genetic or environmental constraints limiting sustainable food production. These include: potential impacts of climate change on aquatic systems, the application of biotechnology, genetics and the development of systems to improve livestock, fish and crop production; approaches to the management of parasites and pathogens; weed control in crops; management of soil fertility; approaches to countering problems of water shortage; reducing post-harvest wastage; the role of advanced engineering and the potential for increasing food production in urban environments.
