The major theme of this book is environmental preservation by controlling release of undesirable greenhouse gases to realize the sustainable development of animal agriculture. Technology exists for the effective collection of methane generated from anaerobic fermentation of animal effluent and its use as a biomass energy source. Fossil fuel consumption can be reduced and there can be increased use of locally available energy sources. In addition, promoting environmentally-conscious agriculture which does not rely on the chemical fertilizer can be realized by effective use of animal manure and compost products.
Since early times, agriculture has been pivotal to England's economy. This seven-volume, eight-piece set compiled by the economist James E. Thorold Rogers (1823-90), represents the most complete record of produce costs in England between the thirteenth and eighteenth centuries. Drawing on a variety of sources including college archives and the Public Record Office, Rogers documents the fluctuating prices of commodities such as livestock, wheat, hay, wool, textiles and labour in a time of great economic change, when the growing economy of the early middle ages was shaken by famine and the Black Death, and then gradually recovered towards the Agrarian Revolution. Published between 1866 and 1902 (Volume 7 having been edited by Rogers' son and published after his death), the whole work provides the statistical basis for research into English agrarian history, and essays which help to interpret the raw data.
Interactions between agriculture, climate and patterns of land use are complex. Major changes in agriculture, and land use patterns are foreseen in the next couple of decades in response to shifts in climate, greenhouse gas management initiatives, population growth and other forces. The book explores key interactions between changes in agriculture, patterns of land use and efforts to reduce greenhouse emissions from agriculture. The volume is based on inter-disciplinary science and policy interactions, exploring the way land use may aid in addressing or be affected by the onset of climate change and alterations in food demand. Future forces shaping land use decisions are examined, and its sensitivity to climate change is highlighted. Patterns of land use and the agricultural role in climate change mitigation are explored. Also, policy and social responses to the new perspectives on future land use patterns are identified. The perspective of the book is beyond the year 2015.
