This book was released on 2013-03-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

Available in PDF, EPUB and Kindle. Book excerpt: The use of simulation models is a necessity and also an aid in the decision-making process in sustainable agricultural systems. Organizing the experimental knowledge of crop production systems without the book keeping and deductive methods of mathematics is very difficult. This book aims to guide readers in the process by which the properties of th

Download or read book Applications of Systems Approaches at the Field Level written by M.J. Kropff and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems approaches for agricultural development are needed to determine rational strategies for the role of agriculture in national development. Mathematical models and computer simulation provide objective tools for applying science to determine and evaluate options for resource management at field, farm and regional scales. However, these tools would not be fully utilizable without incorporating social and economic dimensions into their application. The second international symposium, Systems Approaches for Agricultural Development (SAAD), held in Los Baños, 6-8 December 1995, fostered this link between the biophysical sciences and the social sciences in the selection of keynote papers and oral presentations, a selection of which are included in these books. The contents further reflect how systems approaches have definitely moved beyond the research mode into the application mode. The large number and high quality of interdisciplinary research projects reported from different parts of the globe, to determine land use options that will meet multiple goals and yet sustain natural resource bases, is a key indicator of this `coming of age'. At the farm level, where trade-off decisions between processes and products (commodities) feature strongly, much progress is also evident in the development of systems-based tools for decision making. At the field level optimization of resource use and minimizing environmental effects has become of major concern for which systems approaches are indispensable. The books, of which Volume I deals with regional and farm studies level and Volume II with field level studies, will be of particular interest to all agricultural scientists and planners, as well as students interested in multidisciplinary and holistic approaches to agricultural development.

Book excerpt: A Global Warming Forum: Scientific, Economic, and Legal Overview provides an integrated, thematic approach to major critical aspects of the problem presented by global warming. Scientific issues; economics; natural resource management concerns; and legal, educational, and policy considerations are discussed within the context of arriving at solutions to global warming problems. Data and information is derived from diverse geographic locations, especially in the case history chapters requiring the use of integrated interdisciplinary methods. Graphs and tables are used extensively throughout the text to illustrate key concepts. A Global Warming Forum: Scientific, Economic, and Legal Overview is an excellent survey for researchers in all areas of geoscience and climate assessment, including geochemistry, oceanography, climatology, and resource management.

Available in PDF, EPUB and Kindle. Book excerpt: Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.

Download or read book Handbook of Agricultural Meteorology written by John F. Griffiths and published by . This book was released on 1994 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural meteorology is concerned with the interactions between atmospheric/hydrological factors and agriculture, which in its widest sense includes animal husbandry, forestry, and horticulture. This volume is an up-to-date handbook and guide to this important field. After discussion of the fundamental aspects of the atmospheric, edaphic, and biotic components of the ecosystem, the methods of measuring the important variables are reviewed, with both direct and remote sensing and managing the data taken into account. Discussion of the various agricultural aspects follow, including hydrologic facets, reviews of optimum conditions for temperate and tropical crops as well as livestock, the relationship of pests and diseases to weather, and the role of the atmosphere in forest production. The final section explains weather services for agriculture, how to plan farm management in the light of weather information, the use of crop models, and how to modify existing climate. Economic implications are dealt with in relation to the futures market while the last chapter considers food security on many time and size scales to assist in long-term planning.

Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.
