Book Description
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.

Book Description
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, held in Los Baños, 6-8 December 1995, fostered this link between the bio-physical sciences and the social sciences in the choice of keynote papers and oral presentations, a selection of which is included in this book. The book's 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. This book will be of particular interest to all agricultural scientists and planners, as well as students interested in multidisciplinary and holistic approaches for agricultural development.

Book Description
Most books covering the use of computer models in agricultural management systems target only one or two types of models. There are few texts available that cover the subject of systems modeling comprehensively and that deal with various approaches, applications, evaluations, and uses for technology transfer.

Book Description
In the coming decades the world will need to more than double its food and feed production, almost all of the increase being needed in developing countries. This has socioeconomic and biophysical implications. Traditional component and commodity research addresses overly narrow issues at too small a scale. Rural development needs an eco-regional approach that integrates biophysical and socioeconomic work on cropping systems, livestock, the environment, and natural resources. This book contains the papers, response papers and discussion report of a five-day seminar on eco-regional approaches. It assesses the state of the art of systems approaches applied to eco-regional problems, presenting and discussing a number of case studies. Future research needs are discussed, as well as ways to improve collaboration between research institutes. The seminar on which the book is based was organised on behalf of the Directorate General for International Cooperation of the Netherlands Ministry of Foreign Affairs by the Research Institute for Agrobiology and Soil Fertility (AB-DLO), the Wageningen Agricultural University (WAU), and the International Potato Centre (CIP). It was held at the International Service for National Agricultural Research (ISNAR), and was attended by participants from all CGIAR centres, among others.

Book Description
The World Sustainable Development Outlook series has been developed to provide an overview of sustainable development, to discuss why it is important and to provoke forward thinking on the development of a more coherent approach to solving global problems related to sustainability through science and technology. In doing so, a holistic approach is used to critically examine the interrelationship between the natural, governmental, economic and social dimensions of our world and how science and technology can contribute to solutions. This is a truly global source book, which is reflected in the varied national and cultural origins of the contributors, as well as the topics and case studies covered. Each year a different theme will be covered. The theme of World Sustainable Development Outlook 2007 is the different dimensions of knowledge and technology management in the new era of information revolution and how they relate to sustainable development. Rapid innovation in information and communication technologies (ICTs) is clearly reshaping the world we live in. Countries are increasingly judged by whether they are information-rich or information-poor. It is estimated that 30–40% of the world's economic growth and 40–50% of all new jobs will be IT-driven. Education and knowledge are the chief currencies of the modern age, and can also be a strategic resource and a lifeline for sustainable development. Yet, in Africa, millions of people have never made a telephone call. The technological gulf between developed and developing countries (DCs) is likely to widen further with the rapid expansion of the internet and the speedy transition to digitalisation in the West. The impacts on DCs may include an increase in the so-called brain drain and growing dependence on foreign aid of a different kind – knowledge aid. There are fears that knowledge imperialism is already with us. What is clear is that most of the technological innovations in ICTs are Western-designed and fail to address the needs of the most disadvantaged. The interest of industrialised countries in the use of ICTs in DCs has largely been more concerned with the profitability of their own business enterprises than with any broader goals concerning the development of the host countries. DCs face the challenge of either becoming an integral part of the knowledge-based global economy or the very real danger of finding themselves on the wrong side of the digital divide. Successful management in the new millennium requires developing new methods and approaches to meet the challenges and opportunities of this information revolution while at the same time fostering sustainable development. Adopting a holistic approach, this book aims to critically examine the interrelationship between these different issues in order to reach solutions and a consensus for a better future, taking into account a variety of international, institutional and intellectual perspectives. It uses case and country studies in technological innovation and experience so that lessons in effective management of ICTs can be learned from successful initiatives, ideas and innovations.
