Historic Food Production Shocks: Quantifying the Extremes
Understanding global food production trends is vital for ensuring food security and to allow the world to develop appropriate policies to manage the food system. Over the past few years, there has been an increasing attention on the global food system, particularly after the extreme shocks seen in food prices after 2007. Several papers and working groups have explored the links between food pro...
متن کاملLand as a constraint on food production.
The purpose of this paper is to consider the extent to which the area and quality of land limit the level of food production in the UK. As the population and its disposable income have increased so has the land area devoted to non-agricultural activities. In addition, the area of tree planting has been enlarged to replace the depleted reserves of forest. Simultaneously a great deal of research,...
متن کاملDeveloping a Seamless Sdi Model across the Land-sea Interface
A more integrated and holistic approach to management of spatial information relating to coastal and marine environments is needed and this can be facilitated by the creation of a Spatial Data Infrastructure (SDI) on a seamless platform. There is a growing and urgent need to create a seamless SDI model that bridges the gap between the terrestrial and marine environments, creating a spatially en...
متن کاملSeamless Platform to Facilitate Administration across Land-Sea Interface
As the interface between marine and land environments, coasts have diverse and ever increasing conflicting pressures and demands requiring effective administration and management which is underpinned by the need for access to spatial information. Spatial data is recognised as a critical resource to underpin effective and sustainable management and administration. Spatial Data Infrastructures (S...
متن کاملHuman impacts on fisheries across the land-sea interface.
A long-held paradigm is that estuaries are important to the welfare of estuarine-dependent coastal fisheries, providing spawning areas, suitable salinity gradients for development, protection from predators, and food. Many publications link the beneficial nature of estuaries with fisheries production and decry human activities that modify habitat, and therefore potentially decrease fisheries pr...
