Agricultural System Models in Field Research and Technology Transfer

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. Agricultural System Models in Field Research and Technology Transfer fills this need. It presents the latest advances in the use of various computer models in agricultural management systems. This authoritative reference provides guidance on the use of models in field research, decision support, precision farming, and technology transfer to farmers and ranchers. Derived from an international symposium co-sponsored by the American Society of Agronomy, the Soil Science Society of America, and the USDA's Agricultural Research Service, it analyzes current system model applications for the modeling of natural resources, crop production, grazing lands, and animal production systems. Leading international agricultural system scientists present their experiences and provide guidance on how models can be used to enhance the quality of field research, transfer of research information and technology to farmers and ranchers, and decision support for agricultural management. They provide an expert review of the existing problems and possible solutions to improve future applications. In addition, Agricultural System Models in Field Research and Technology Transfer explores the possible use of an international modular computer framework to improve current modeling procedures in an effort to develop problem-specific models in the future.

Book Description

Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that is accumulated on the epidermal tissues in rice. These effects are expressed most clearly under high-density cultivation systems with heavy applications of nitrogen. Si is therefore recognized now as an ''agronomically essential element'' in Japan.

Book Description

Knowledge intensiveness has featured prominently in most strategies to promote agricultural development. In the past strengthened research systems may have increased the supply of new knowledge and technologies, but that has not necessarily translated into enhanced agricultural growth. Knowledge converts into products and services through an innovation system -- a network of organizations, enterprises and individuals focusing on bringing new knowledge into economic use, together with the institutions and policies that enable a well-functioning network. This book assesses the usefulness of the innovation systems concept in guiding investments to support knowledge intensive, sustainable agricultural development for developing countries and its collaborators.

Book Description

Despite the vast number of books and reports on tropical deforestation, there's confusion about the causes of forest loss and forest poverty, and the effectiveness of policy responses. At Loggerheads seeks to describe ways to reconcile pressures for agricultural expansion in the tropics with the urgent needs for both forest conservation and poverty alleviation. It diagnoses the causes and impacts of forest loss and the reasons for the association of forests and poverty. It looks at how policies - modulated by local conditions - act simultaneously on deforestation and poverty, creating tradeoffs or complementarities, depending on the situation. The report brings to the surface problems that impede adoption of favourable policies, describing institutional and technological innovations that might help overcome these impediments.

Whose Names Are Unknown: A Novel

ASIN: 0292714459

Book Description

The 1930s exodus of "Okies" dispossessed by repeated droughts and failed crop prices was a relatively brief interlude in the history of migrant agricultural labor. Yet it attracted wide attention through the publication of John Steinbeck's The Grapes of Wrath (1939) and the images of Farm Security Administration photographers such as Dorothea Lange and Arthur Rothstein. Ironically, their work risked sublimating the subjects—real people and actual experience—into aesthetic artifacts, icons of suffering, deprivation, and despair. Working for the Farm Security Administration in California's migrant labor camps in 1938-39, Sanora Babb, a young journalist and short story writer, together with her sister Dorothy, a gifted amateur photographer, entered the intimacy of the dispossessed farmers' lives as insiders, evidenced in the immediacy and accuracy of their writings and photos. Born in Oklahoma and raised on a dryland farm, the Babb sisters had unparalleled access to the day-by-day harsh reality of field labor and family life.

This book presents a vivid, firsthand account of the Dust Bowl refugees, the migrant labor camps, and the growth of labor activism among Anglo and Mexican farm workers in California's agricultural valleys linked by the "Dirty Plate Trail" (Highway 99). It draws upon the detailed field notes that Sanora Babb wrote while in the camps, as well as on published articles and short stories about the migrant workers and an excerpt from her Dust Bowl novel, Whose Names Are Unknown. Like Sanora's writing, Dorothy's photos reveal an unmediated, personal encounter with the migrants, portraying the social and emotional realities of their actual living and working conditions, together with their efforts to organize and to seek temporary recreation. An authority in working-class literature and history, volume editor Douglas Wixson places the Babb sisters' work in relevant historical and social-political contexts, examining their role in reconfiguring the Dust Bowl exodus as a site of memory in the national consciousness.

Focusing on the material conditions of everyday existence among the Dust Bowl refugees, the words and images of these two perceptive young women clearly show that, contrary to stereotype, the "Okies" were a widely diverse people, including not only Steinbeck's sharecropper "Joads" but also literate, independent farmers who, in the democracy of the FSA camps, found effective ways to rebuild lives and create communities.

The Great Migration to California in 1930s.......2007-06-22

For fifty-eight days in the summer of 1934, temperatures in the High Plains exceeded 100 degrees, with almost no rain. In the Texas Panhandle near Dalhart, as well as in other High Plains states, a black blizzard of dust turned day into night. The wind raged endlessly, blowing the Texas top soil into Oklahoma, where it mixed with the red Oklahoma soil, and blew into Arkansas and Kansas and Colorado. It destroyed car engines, choked cattle to death, buried houses under mountains of sand. People got sick with respiratory illnesses, "dust pneumonia" they called it. Traffic stopped. Schools and businesses closed. Ruined farms were abandoned.

Those that made it through 1934, did not survive in 1936 when the dust storms returned, this time accompanied by a plague of grasshoppers that devoured their dryland crops. It was the middle of the Great Depression, and those people already living on the edge fell off the precipice.

"On the Dirty Plate Trail" is about the Great Migration that ensued as a result of the Dust Bowl. The title refers to Highway 99, which took the refugees from peas in California's Imperial Valley to cotton in the San Joaquin Valley to peaches and prunes in the Sacramento Valley as farmers without farms suddenly became migrant workers. They were called Okies no matter which state they hailed from, and they were exploited by labor contractors, abused by locals, and blamed by society for their own troubles. They lived in squatters camps, or shacks rented to them by the farm bosses, or if they were lucky, in tent cities provided by the Farm Security Administration. Conditions were often deplorable, and many died of disease, in childbirth or by accident.

In 1929, the Babb sisters, Sanora and Dorothy, had come to California from Kansas. It was because of their farmer's daughters background that they were accepted as insiders by the refugees. While visiting the camps, Sanora made "field notes" intended for use in the Dust Bowl novel she was writing, and Dorothy snapped pictures with her camera.

Years later, Dorothy's well-documented photographs were found in a brown paper sack and given by relatives to Douglas Wixson, who matched the photographs with Sanora's field notes to create this stunning volume. The photographs alone are worth the price. These candid images unveil the migrant story of hunger and misery, laughter and music, mud and squalor, pride and picket lines.

"Migration is as old as humankind and as recent as today," says Douglas Wixson, noting in his Preface that as he finished the final draft of this book, refugees from Hurricane Katrina were pouring from flood-stricken New Orleans and other devastated cities on the Gulf Coast, "like shifting currents of water ... separate, little noticed, yet indispensable to our economy."

Book Description

As in many other sectors, in agribusiness major changes are taking place. On the demand side, consumers are changing lifestyles, eating and shopping habits, and increasingly are demanding more accommodation of these needs in the supermarket. With regard to the supply: the traditional distribution channel dominators - manufacturers of branded consumer products - are trying hard to defend their positions against retailers, who gather and use information about the consumer to streamline their enterprises and strengthen their ties with the consumer. The agricultural producers, meanwhile, face increased regulations with regard to food additives, pesticides, and herbicides. Pressures rise as their business becomes more specialized and capital-intensive than that of their predecessors. Finally, the larger political climate is not so favorable to agriculture, which now has to compete in the global market without significant government support. This title describes and interprets changes in the domain of agriculture and food. The contributors develop the theme of taking an interdisciplinary approach to coping with these changes, using concepts and methods developed in general marketing, which are adapted so as to apply to the particular characteristics of the food and agriculture sector. This book is published to honor the distinguished career of Professor Mathew T.G. Meulenberg from Wageningen Agricultural University, on the occasion of his retirement in September 1996. As a scientist, teacher, and advisor to the agribusiness and the government, Professor Meulenberg has made an important contribution to the development of marketing, inside and outside the domain of agriculture.
