Global Change and Food Production

Global change and food and forest production: future scientific challenges

Production of food and forest products will need to increase to meet the world’s projected demand. This challenge can be met by either extensification or intensification but, with little new land available for agriculture in many regions of rapid population growth, intensification will be pre-eminent. Global, average cereal yields will need to rise from the current 2.9 to 4.2 Mg ha−1 by 2025. T...

CLIMATE CHANGE AND FOOD PRODUCTION by Tim Curtin (Australia) CLIMATE CHANGE AND FOOD PRODUCTION

The availability of atmospheric carbon dioxide is the sine qua non for all plant growth and thence for all marine and terrestrial life forms. The purpose of this paper is to show that proposed reductions in anthropogenic emissions of carbon dioxide (CO2) to below the level of observed annual incremental biospheric absorption of those emissions would reduce the growth of the basic feedstock of a...

Food and forestry: global change and global challenges

Agricultural and forestry production have a well established dependence on climate. There is, therefore, growing concern about the potentially wide-ranging impacts that climate change would have on these key industries as the nature and extent of anticipated changes become more evident. “Global Change” however encompasses far more than change in climate alone. It also includes changes in climat...
