This book reports on the results of experiments to assess the effects of global climate change on the agricultural production of crops and livestock. It covers issues such as the CO2 fertilization effect, the adverse effects of elevated levels of UV-B radiation and ozone on plant growth and productivity, and on livestock. Combined effects are also studied, including changing CO2, temperature, and UV-B radiation and O3 simultaneously on crop growth. The concluding chapters give an idea of the overall global picture in terms of the effects already discussed. Changes in the world hydrological cycle, the regional availability of water resources, changes in soil conditions and the impact of this on food production, as well as modelling techniques, are all examined.
