Book Description
This paper outlines crop improvement, strategic agronomy, and natural resource management research concerns central to CIMMYT¦s mission and which models can help address. Authors also discuss related issues, including model documentation and data management. Although CIMMYT has little comparative advantage in model development per se, the center has much to contribute to others' development and refinement efforts, to the availability of quality data, and to the promotion of models and training in their use, and active participation in these areas will ultimately result in better models for CIMMYT's own aims.

Book Description
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.

Book Description
Recent advances in gene technology, plant transformation, and the growing knowledge of DNA sequences of plants as well as of their most important parasites and symbionts offer many interesting prospects for the breeding of new crop varieties. This was not only recognized by the major seed companies, but also by the governments of developing countries and by worldwide foundations supporting their agriculture. The know-how gained by the seed companies on crops important for the agricultural industry in developed countries could easily be provided for free to the international and national organizations dedicated to development of crops important in the third world. Results obtained worldwide become easily available to everybody through the scientific literature. Likewise, agricultural research in, e.g., the USA or Europe profits from the natural plant gene pool available in the third world. All this definitely provides for the possibility of fast change, new prosperity and security of food supply in the whole world, if properly applied. The fast development also asks for ethical and sociopolitical considerations, whereby not doing the right can be as much a mistake as doing the wrong.

Book Description
In The Globalization of Wheat, Marci R. Baranski explores Norman Borlaug’s complicated legacy as godfather of the Green Revolution. Winner of the Nobel Peace Prize in 1970 for his role in fighting global hunger, Borlaug, an American agricultural scientist and plant breeder who worked for the Rockefeller Foundation, left a legacy that divides opinions even today. His high-yielding dwarf wheat varieties, known as miracle seeds, effectively doubled and tripled crop yields across the globe, from Kenya to India and Argentina to Mexico due to their wide adaptation. But these modern seeds also required expensive chemical fertilizers and irrigation, both of which were only available to wealthier farmers. Baranski argues that Borlaug’s new technologies ultimately privileged wealthier farmers, despite assurances to politicians that these new crops would thrive in diverse geographies and benefit all farmers. As large-scale monocultures replaced traditional farming practices, these changes were codified into the Indian wheat research system, thus limiting attention to traditional practices and marginal environments. In the shadow of this legacy, and in the face of accelerating climate change, Baranski brings new light to Borlaug’s role in a controversial concept in agricultural science.

Book Description
The perceived limits to producing food for a growing global population have been a source of debate and preoccupation for ages. Both experts and the public have been vigilant when regarding the world food situation and outlook. The global agricultural vision has recently moved from eliminating hunger and poverty to a new focus on food security, nutritional security, climate change and economic opportunity. The overall approach can be classified into four strands: food for peace, food for growth, food for the planet, and food for health. This book discusses global agricultural revolutions and visions both in general and from regional, continental and national perspectives, with a particular focus on the World Trade Organization and markets. It will serve as inspiration for historians, practitioners and policy-makers in the field of global agriculture in determining a roadmap for global leaders in years to come.

Book Description
Model studies focus experimental investigations to improve our understanding and performance of systems. Concentrating on crop modelling, this book provides an introduction to the concepts of crop development, growth, and yield, with step-by-step outlines to each topic, suggested exercises and simple equations. A valuable text for students and researchers of crop development alike, this book is written in five parts that allow the reader to develop a solid foundation and coverage of production models including water- and nitrogen-limited systems.

Book Description
As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world's population. This study assesses how serious the danger to food security might be and suggests some steps policymakers can take to remedy the situation.Using various modeling techniques, the authors project 15 different future scenarios for food security through 2050. Each scenario involves an alternative combination of potential population and income growth and climate change. The authors also examine the specific test case of a hypothetical extended drought in South Asia, to demonstrate the possible effects of increased climate variability on a particular world region. They conclude that the negative effects of climate change on food security can be counteracted by broad-based economic growthparticularly improved agricultural productivityand robust international trade in agricultural products to offset regional shortages. In pursuit of these goals, policymakers should increase public investment in land, water, and nutrient use and maintain relatively free international trade. This inquiry into the future of food security should be of use to policymakers and others concerned with the impact of climate change on international development.

Book Description
This publication presents a GIS-based approach for revising the definitions of global maize production environments, called “mega-environments” (MEs), used by CIMMYT and its partners. A cluster analysis was performed on climate data, representing a four-month growing season, for key maize producing locations. Assuming rainfed production, the onset of the growing season was determined based on the month when the ratio of precipitation over potential evapotranspiration exceeds 0.5. Diagnostic criteria for mapping MEs were based on cluster analysis results and expert knowledge. The resulting maps can be used to select appropriate target environments for maize germplasm and trials, as well as in priority setting and site selection for global maize breeding programs.
