Download or read book Scenario Studies for the Rural Environment written by Job F.Th. Schoute and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural areas need to fulfil a large variety of functions and to accommodate many activities. The complexity of the problems, limited funds, and the almost irreversible character of some interventions result in a compelling need to evaluate ex ante the effects of alternative solutions for designation of land, for measures to develop infrastructure, and for soil and water management. Scenario studies are undertaken to help manage the complexity, to place bounds on uncertainties, and to create new visions. After an overview of the nature, variety and scope of scenario studies, the book illuminates various European examples and reviews, under the following headings: regional soil and water management; nature development and landscape quality; rural planning and the future of regions.

Download or read book Opportunities use and transfer of systems research methods in agriculture to developing countries written by Goldsworthy and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 1993, ISNAR, in collaboration with International Consortium for Application of Systems Approaches, organized a three-day workshop on systems approaches and modelling for agricultural development. Sponsored by the Dutch Ministry for Development Cooperation, the workshop was attended by participants from 12 national agricultural research systems (NARS), nine international agricul tural research centers (lARCs), and five advanced research organizations (AROs). Although application of systems approaches in agricultural research and resource management is a rather new field, there is already increasing demand for implemen tation of these approaches. This will require a critical mass of specialists in the NARS and IARCs. Before this critical mass can be obtained, however, the experience that has been gained in this area needs to be evaluated, further possibilities need to be explored, and new objectives and targets need to be set. This book, which contains the papers presented at the workshop, assesses the state of the art of systems approaches in agricultural research, resource management, and rural planning. It also gives an impression of the evolution of this interdisciplinary field and its use in national and international research centers. Another, less tangible, outcome of the workshop was its contribution toward strengthening the network of NARS, lARCs, and AROs. It gave participants and organizers a chance to develop contacts, and provided an opportunity to make the first proposals for collaborative programs. Special thanks are due to Peter Goldsworthy and Luc Boerboom for their crucial role in making the workshop a success in this regard.

Download or read book Understanding Options for Agricultural Production written by G.Y. Tsuji and published by Springer Science & Business Media. 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.

This book was released on 1995 with total page 991 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fragile lives in fragile ecosystems: Feeding the world's poor from neglected rice ecosystems was the theme of the 1995 International Rice Research Conference. During the February meeting, participants assessed progress in rice research and identified new research approaches for reducing constraints and improving productivity and sustainability of less favored and fragile rice producing areas - these are the upland, rainfed lowland, and flood-prone ecosystems.
Download or read book Photoassimilate Distribution Plants and Crops Source Sink Relationships written by Zamski and published by Routledge. This book was released on 2017-09-29 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adopting an interdisciplinary approach to the study of photoassimilate partitioning and source-sink relationhips, this work details the major aspects of source-sink physiology and metabolism, the integration of individual components and photoassimilate partitioning, and the whole plant source-sink relationships in 16 agriculturally important crops. The work examines in detail the components of carbon partitioning, such as ecology, photosynthesis, loading, transport and anatomy, and discusses the impact of genetic, environmental and agrotechnical factors on the parts of whole plant source-link physiology.
