Book Description
In this book we assemble a range of evidence from a range of sources with a view to developing an improved understanding of recent trends in agricultural productivity around the world. The fundamental purpose is to better understand the nature of the long-term growth in the supply of food and its principal determinants. We pursue this purpose from two perspectives. One is from a general interest in the world food situation in the long run. The other is from an interest in the implications of U.S. and global productivity patterns for U.S. agriculture.

Book Description
Throughout much of its history, the United States was predominantly a rural society. The need to provide sustenance resulted in many people settling in areas where food could be raised for their families. Over the past century, however, a quiet shift from a rural to an urban society occurred, such that by 1920, for the first time, more members of our society lived in urban regions than in rural ones. This was made possible by changing agricultural practices. No longer must individuals raise their own food, and the number of person-hours and acreage required to produce food has steadily been decreasing because of technological advances, according to Roundtable member James Merchant of the University of Iowa. The Institute of Medicine's Roundtable on Environmental Health Science, Research, and Medicine held a regional workshop at the University of Iowa on November 29 and 30, 2004, to look at rural environmental health issues. Iowa, with its expanse of rural land area, growing agribusiness, aging population, and increasing immigrant population, provided an opportunity to explore environmental health in a region of the country that is not as densely populated. As many workshop participants agreed, the shifting agricultural practices as the country progresses from family operations to large-scale corporate farms will have impacts on environmental health. This report describes and summarizes the participants' presentations to the Roundtable members and the discussions that the members had with the presenters and participants at the workshop.

Book Description
At the center of what was once the tallgrass prairie, Iowa has stood out for clearing the land and becoming one of the most productive agricultural states in the nation. But its success is challenged by multiple issues including but not limited to a decline in union representation of meatpacking workers; lack of demographic diversity; the advent of job-replacing mechanization; growing income inequality; negative contributions to and effects of climate change and environmental hazards. To become green, fair, and prosperous, Connerly argues that Iowa must reckon with its past and the fact that its farm economy continues to pollute waterways, while remaining utterly unprepared for climate change. Iowa must recognize ways in which it can bolster its residents’ standard of living and move away from its demographic tradition of whiteness. For development to be sustainable, society must balance it with environmental protection and social justice. Connerly provides a crucial roadmap for how Iowans can move forward and achieve this balance.

Book Description
Agricultural Productivity: Measurement and Sources of Growth addresses measurement issues and techniques in agricultural productivity analysis, applying those techniques to recently published data sets for American agriculture. The data sets are used to estimate and explain state level productivity and efficiency differences, and to test different approaches to productivity measurement. The rise in agricultural productivity is the single most important source of economic growth in the U.S. farm sector, and the rate of productivity growth is estimated to be higher in agriculture than in the non-farm sector. It is important to understand productivity sources and to measure its growth properly, including the effects of environmental externalities. Both the methods and the data can be accessed by economists at the state level to conduct analyses for their own states. In a sense, although not explicitly, the book provides a guide to using the productivity data available on the website of the U.S. Department of Agriculture/Economic Research Service. It should be of interest to a broad spectrum of professionals in academia, the government, and the private sector.

Book Description
"An Introduction to Iowa's Environmental Problems is an edited volume with 17 contributors besides Connie Mutel herself-all Iowa authors who are scientific experts in the field. Geared toward course adoption in Iowa and Midwest classrooms, it will fill a need for a comprehensive, but accessible and brief overview of the environmental issues Iowa faces, and what we can do about them. Specifically, the volume breaks down the issues surrounding Iowa's land and soils, water, atmosphere, and loss of biological diversity. Teachers lack a go-to resource for explaining this topic to their students, and many Iowans remain unaware of the environmental impacts of farming. And with the new administration's focus on environmental concerns, including climate change, the timing is right to change that. At this point, Iowa can choose a route toward becoming an agricultural factory that disregards nature's sustainability and resilience, or we can steer toward a saner future that recognizes and honors our soils, climate, water, and native species. With this book, Mutel will help guide future Iowa leaders toward the latter"--

Book Description
Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

Book Description
The Atlas of Iowa examines the state's geography, demographics, agriculture, and political/cultural patterns. Drawing upon archival materials and synthesizing little-known secondary sources, the authors of this thematic atlas have pulled together a comprehensive map series that depicts Iowa's complex, unique story of challenging human-environmental interaction.

Book Description
'Action is needed to fight poverty by sustaining the environment and the use of natural resources. Land Quality, Agricultural Productivity, and Food Security explores a range of factors driving food security. The book offers an assessment to link quality of the available land resources with productivity of land and the ability to ensure food security. It offers a mixture of broad-scale assessments across the globe, with detailed case studies, deepening our understanding of economics and decision-making mechanisms. It is recommended to researchers, as well as actors in the private and public domain, who are keen to improve their understanding of the appropriate actions that ensure food security in the decade to come.' - Floor Brouwer, Agricultural Economics Research Institute (LEI), The Hague, The Netherlands Land quality and land degradation affect agricultural productivity and food security, but quantifying these relationships has been difficult. Data are extremely limited and outcomes are sensitive to the choices that farmers make. The contributors to this book - including soil scientists, geographers, and economists - analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: * the extent to which differences in land quality generate differences in agricultural productivity across countries * how farmers' responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and * whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.
