      Irrigation Systems

      Design, Planning and Construction

      by Adrian Laycock

      Of all the confrontations man has engineered with nature, irrigation systems have had the most widespread and far-reaching impact on the natural environment. Over a quarter of a billion hectares of the planet are irrigated and entire countries depend on irrigation for their survival and existence. Considering the importance of irrigation schemes, it is unfortunate that until recently the technology and principles of design applied to their construction has hardly changed in 4,000 years. Modern thinking on irrigation engineering has benefited from a cross-fertilization of ideas from many other fields including social sciences, control theory, political economics and agriculture. However, these influences have been largely ignored by irrigation engineers.Drawing on almost 40 years of experience of irrigation in the developing world, Laycock introduces new ideas on the design of irrigation systems and combines important issues from the disciplines of social conflict, management, and political thinking.

      Soil Biodiversity in Amazonian and Other Brazilian Ecosystems

      by Edited by Fattima M S Moreira, Jose O Siqueira, Lijbert Brussaard

      The loss of biological diversity has become an increased concern over recent years and is now enshrined in international conventions. Most biodiversity in fact occurs in the soil. Soil organisms (especially bacteria, fungi and soil invertebrates) play a major role in the formation of soil structure and are primary agents of decomposition and are drivers of nutrient cycling, and hence agricultural production.This book reviews soil biodiversity in one of the key biodiversity hotspots of the world, i.e. the Amazon and nearby regions of Brazil. It covers both the tropical savannah and rain forests . The work reported is based on a project "Conservation and Sustainable Management of Below-Ground Biodiversity", executed by TSBF-CIAT with co-financing from the Global Environment Facility (GEF) and implementation support from the United Nations Environment Programme (UNEP). The book represents a major contribution to the literature and will interest those in biodiversity conservation, soil scienceand ecology and biodiversity conservation.

      Nitrate, Agriculture and the Environment

      by Tom Addiscott

      There is widespread public concern about the effects of nitrate derived from farming on water quality and public health. But research on nitrate during the past decade has revealed wide discrepancies between public perceptions and reality. The main problems from nitrate are ecological changes in coastal and estuarine waters and nitrous oxide in the atmosphere. This gas, largely derived from nitrate, is a threat to the ozone layer in the stratosphere and is also a greenhouse gas. This book builds on Farming, Fertilizers and the Nitrate Problem (CABI, 1991) by Addiscott, Whitmore and Powlson but has been restructured to take account of new developments and to bring out more clearly the role of politicians and economists in the 'nitrate problem'.

      Environmental Impacts of Sugar Production

      by Oliver Cheesman

      Pressure from conservationists and increasing regulation, means that environmental considerations are increasingly important for the sugar industry. This book examines the environmental impacts of the sugar industry in relation to the cultivation of sugar crops (cane and beet) and the processing of the raw materials that they yield. These include soil erosion, loss of natural habits leading to a reduction in biodiversity, excessive water consumption, water and air pollution, and runoff and leaching of nutrients. Whilst some of these impacts are essentially generic impacts of agriculture, others, such as those relating to irrigation, are more specific to the cultivation of sugar crops. The book also investigates the utilization of waste materials from sugar production, and explores methods of reducing the environmental impacts of sugar production and processing.
