Global food and farming futures
نویسنده
چکیده
Food is an essential part of all our lives. Following productivity increases in the Green Revolution, food prices in major world markets have been at a historical low in recent decades. Analysis from the Government Office for Science shows that by 2050, this situation is set to change significantly. The global population will have increased by nearly a third to nine billion, and diets will have changed with increasing affluence, leading to a much increased demand for food. At the same time, the food supply may be threatened as agriculture will have to compete with industry and municipal uses for energy and water. Climate change will also have adverse impacts on production in some areas. The challenge is not only to increase food production, but to do so in a way that is sustainable, reducing our greenhouse gas emissions and preserving biodiversity. In addition, as demonstrated by the 2006–2008 food price spike, we must make the food system more resilient to volatility, both economic and climatic. A further challenge is that of ending hunger; currently around 1 billion people are hungry, and we must work to ensure that this number decreases rather than increases in the future. Meeting these challenges will involve social and political solutions as well as those based on the natural sciences. The need for action is urgent given the time required for investment in research to deliver new technologies to those who need them, and for

متن کاملSpeculation on commodities futures markets and destabilization of global food prices: exploring the connections.
In December 2010, the United Nations Food and Agriculture Organization's Food Price Index surpassed its previous peak of June 2008, and prices remained at this level through September 2011. This pattern is creating justified fears of a renewal or intensification of the global food crisis. This paper reviews arguments and evidence to inform debates on how to regulate commodity futures markets in...
متن کاملRoof Top Farming a Solution to Food Security and Climate Change Adaptation for Cities
Two distinct phenomena shape our planet: more than half of the world’s human population is urbanised (World Watch Institute 2007); and global warming induced climate change is a grave threat. Modern cities, in ecological terms, have become parasitic energy and resource ‘sinks,’ consuming 75% of the world’s resources on only 2% of the global land area (TFPC 1999). In this way cities ‘short-circu...
متن کاملFORESIGHT PROJECT ON GLOBAL FOOD AND FARMING FUTURES The application of science and technology development in shaping current and future aquaculture production systems
Aquaculture development over the past 50 years has been facilitated largely by the application of science and the introduction of new technologies. Although aquaculture is a very diverse sector in products, production systems and business structures, almost every activity has benefited from scientific advances. However, the impact of technological progress is most clearly seen where there has a...
