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...

Global Warming and the Future of

This article briefly outlines the cause of global warming, its trends and consequences as indicated by the International Panel on Climate Change. Sea-level rise is one consequence of particular concern to Pacific island states. It also reviews the views of economists about connections between economic growth and global warming. Whereas the majority of economists did not foresee a conflict betwe...

Mechanisms driving change: altered species interactions and ecosystem function through global warming.

1. We review the mechanisms behind ecosystem functions, the processes that facilitate energy transfer along food webs, and the major processes that allow the cycling of carbon, oxygen and nitrogen, and use case studies to show how these have already been, and will continue to be, altered by global warming. 2. Increased temperatures will affect the interactions between heterotrophs and autotroph...

Land use pattern, forest migration, and global warming

Range limits of many plant species are expected to shift dramatically if climatic warming, driven by the release of greenhouse gases, occurs in the next century. The ability of species to migrate in response to the range shifts has been questioned, especially in the context of extensive habitat fragmentation which occurs in modem-day landscapes. Simulation models are presented which incorporate...

An ecosystem context for global gross forest cover loss estimates.

F undamental questions remain about the contributions of forests to the global carbon cycle and how these are affected by natural and anthropogenic drivers. Deforestation, the human-induced conversion of forests to non-forest land, currently accounts for an estimated 12% of anthropogenic carbon emissions (1). The future response of forests to global climate change could result in substantial po...
