Bridlington, Whitby, and other English coastal towns have long depended on the North Sea fishery for food and income.2 But global warming is affecting plankton and changing the marine food chain, compounding the pressures of overfishing.3 The resulting disruption of the ecosystem could damage the fishing industry and hurt North Sea coastal communities from the United Kingdom to Scandinavia.

The scope of this chapter, with a focus on food crops, pastures and livestock, industrial crops and biofuels, forestry (commercial forests), aquaculture and fisheries, and small - holder and subsistence agriculturalists and artisanal fishers, is to: examine current climate sensitivities / vulnerabilities; consider future trends in climate, global and regional food security, forestry and fisheries production; review key future impacts of climate change in food crops pasture and livestock production, industrial crops and biofuels, forestry, fisheries, and small - holder and subsistence agriculture; assess the effectiveness of adaptation in offsetting damages and identify adaptation options, including planned adaptation to climate change; examine the social and economic costs of climate change in those sectors; and, explore the implications of responding to climate change for sustainable development.
