Systems approaches for agricultural development


Book Description

The symposium In the next decades, agriculture will have to cope with an ever-increasing demand for food and raw basic materials on the one hand, and with the necessity to use resources without further degrading or exhausting the environment on the other hand, and all this within a dynamic framework of social and economic conditions. Intensification, sustainability, optimizing scarce resources, and climate change are among the key issues. Organized thinking about future farming requires forecasting of consequences of alternative ways to farm and to develop agriculture. The complexity of the problems calls for a systematic approach in which many disciplines are integrated. Systems thinking and systems simulation are therefore indispensable tools for such endeavours. About 150 scientists and senior research leaders participated in the symposium 'Systems Approaches for Agricultural Development' (SAAD) at the Asian Institute of Technology (AIT), Bangkok, Thailand, in December 1991. The symposium had the following objectives: - to review the status of systems research and modeling in agriculture, with special reference to evaluating their efficacy and efficiency in achieving research goals, and to their application in developing countries; - to promote international cooperation in modeling, and increase awareness of systems research and simulation. The symposium consisted of plenary sessions with reviews of major areas in systems approaches in agriculture, plus presentations in two concurrent sessions on technical topics of systems research. Subjects of studies were from tropical and temperate countries.




Agricultural Systems Modeling and Simulation


Book Description

Offers a treatment of modern applications of modelling and simulation in crop, livestock, forage/livestock systems, and field operations. The book discusses methodologies from linear programming and neutral networks, to expert or decision support systems, as well as featuring models, such as SOYGRO, CROPGRO and GOSSYM/COMAX. It includes coverage on evaporation and evapotranspiration, the theory of simulation based on biological processes, and deficit irrigation scheduling.




Resource Allocation Theory Applied to Farm Animal Production


Book Description

This book is about resource allocation matters with the aim to further development thoughts and models on resource allocation applied to livestock production. It contains 18 chapters divided into 4 parts which discuss resources and resource allocation patterns, trade-offs, metabolic constraints to resource allocation and the process of homeorhesis with a special emphasis to homeorhesis during heat stress; the relationship between food intake and resources allocated to body maintenance, growth, reproduction and the immune response; the consequences of high production efficiency in pigs, poultry and dairy cattle and the consequences of improved production by means of biological engineering and options to include resource allocation matters in the breeding objective, animal welfare and in resource allocation modelling.




Whole Grains and Health


Book Description

Whole Grains and Health presents a science-based discussion of whole grains and their expanding role in health and disease. An international collection of authors presents current perspectives on grains, the many opportunities for further research into whole grains and the remarkable growth potential for product development. Coverage includes discussions on the health benefits of a diet rich in whole grains, the functional components of whole grains and the regulatory nuances of labeling grain products. A unique feature is a section devoted to communicating with consumers. Barriers exist which affect consumer acceptance and use of whole-grain foods. Whole Grains and Health addresses those concerns and offers strategies for furthering research, product development and educational outreach.

Charts, tables, and illustrations make the information easy to access and understand. An ideal textbook for graduate and undergraduate courses in agronomy as well as a comprehensive reference for professionals involved in cropping systems research, Cropping Systems: Trends and Advances is a book you’ll refer to again and again. Topics covered in this well-referenced and thoughtfully indexed book include: emerging trends in cropping systems research designing resource-efficient cropping systems soil quality and fertility tillage root dynamics water quality concerns nitrogen use efficiency precision agriculture agricultural biotechnology weed biology and management integrated pest management the important role that cover crops can play key indicators for assessing nitrogen use efficiency in cereal-based agroecosystems the implications of elevated carbon dioxide-induced changes in agroecosystem productivity and a great deal more!




Intensive Agriculture and Sustainability


Book Description

As globalization restructures agriculture and rural communities, the impacts of increasingly industrialized farming make interdisciplinary analyses of the linkages among the social, environmental, and economic aspects of farming ever more vital. This collection analyzes the reasons for the public’s scrutiny of intensive agriculture and the prospects for sustainable farming now that concerns are mounting about food quality, manure runoff, greenhouse gases, extra-label use of antibiotics, pesticide use, and rural conflict. Intensive Agriculture and Sustainability outlines the advantages of Farming Systems Analysis for understanding the implications of modern, intensive agriculture. This book describes some of the major environmental and social problems connected with intensive farming; outlines a framework for analyzing its sustainability; discusses key linkages among the environmental, economic, and social indicators; outlines modelling trade-offs between profitability and environmental sustainability; and then analyzes various farming systems using case studies. The authors conclude that rural conflict and government regulation are likely to continue unless the public joins with farmers to help fund stewardship practices and stabilize farm incomes. This book will appeal to field practitioners, agricultural and environmental policy analysts, geographers, and those scholars and students who are tired of the pervasive production-oriented disciplinary focus that typifies most agricultural research.

Sustainable Intensification in Smallholder Agriculture


Book Description

Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.




Agroforestry in Sustainable Agricultural Systems


Book Description

Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.
