Obesity Economics For The Western United States, Mariah D. Ehmke, Tina Willson, Christiane Schroeter, Ann Marie Hart, Roger Coupal
Obesity Economics For The Western United States, Mariah D. Ehmke, Tina Willson, Christiane Schroeter, Ann Marie Hart, Roger Coupal
Agribusiness
The estimated obesity-related health care costs across the Western region in 2008 were $16.2 billion (this is an inflation-adjusted estimate based on the work of Finkelstein, Fiebelkorn, and Wang (2004)). 25 The Western populations, the percentage of obese adults in each state, and the estimated annual obesity-related expenditures by state are summarized in Table 1. The cost estimates include only direct health care expenditures related to obesity. The actual cost of obesity is much higher and includes not only obesity-related illness and disease, but also indirect costs resulting from missed work days and lower worker productivity as well as valued …
Managing Maize Production In Shifting Cultivation Milpa Systems In Yucatan, Through Weed Control And Manure Application, David Parsons, Luis Ramirez-Aviles, Jerome H. Cherney, Quirine M. Ketterings, Robert W. Blake, Charles F. Nicholson
Managing Maize Production In Shifting Cultivation Milpa Systems In Yucatan, Through Weed Control And Manure Application, David Parsons, Luis Ramirez-Aviles, Jerome H. Cherney, Quirine M. Ketterings, Robert W. Blake, Charles F. Nicholson

Milpa cultivation involving cutting an area of forest, burning, and planting crops has existed in the Yucatán Peninsula for more than three millennia. Fallow periods are short and decreasing, leading to a productivity collapse of the system. Technologies that increase yield and maintain plots under cultivation have the potential to decrease the land area needed for family food production, resulting in more mature forests. This study was undertaken to examine the relative importance and potential interactions of declining fertility and increasing weed pressure in reducing maize (Zea mays L.) yields, and to examine the effectiveness of combinations of weed …
Modeling Feedback Between Economic And Biophysical Systems In Smallholder Agriculture In Kenya: The Crops, Livestock And Soils In Smallholder Economic Systems (Classes) Model, Emma C.

We investigate natural resource-based poverty traps using a simulation model of smallholder farms in highland Kenya. Simulation modeling allows for detailed examination of the complex interactions and feedback between farm-household economic decision-making and long-term soil dynamics, which may contribute to persistent poverty among smallholders in this region. We examine the effects of changing initial endowments of land, labour and stocks of on-farm soil organic matter on the long-term welfare of these households. We find that larger farms are better able to cope with both labour shocks and deteriorating natural capital than smaller farms, with smaller farms remaining poor and unable …
Setting Agricultural Science Strategy In Tumultuous Economic Times, Jennifer S. James, Julian M. Alston, Philip G. Pardey
Setting Agricultural Science Strategy In Tumultuous Economic Times, Jennifer S. James, Julian M. Alston, Philip G. Pardey
Agribusiness
The international competitiveness and prosperity of U.S. agriculture depends on steady and rapid productivity growth fueled by public agricultural research and development (R&D). Agricultural science benefits consumers and the environment, not just farmers. Enhanced productivity as a result of agricultural R&D means that consumers have access to a more abundant, cheaper, safer, higher quality, and more diverse and convenient food supply, produced with less stress on natural resources and the environment. From a global perspective, productivity growth allows agricultural production to increase faster than demand; food has become much cheaper over time in spite of a rapidly growing world population …

The Economics Of Agricultural R&D, Julian M. Alston, Philip G. Pardey, Jennifer S. James, Matthew A. Andersen
Agribusiness
Agricultural research has transformed agriculture and in doing so contributed to the transformation of economies. Economic issues arise because agricultural research is subject to various market failures, because the resulting innovations and technological changes have important economic consequences for net income and its distribution, and because the consequences are difficult to discern and attribute. Economists have developed models and measures of the economic consequences of agricultural R&D and related policies in contributions that relate to a very broad literature ranging across production economics, development economics, industrial organization, economic history, welfare economics, political economy, econometrics, and so on. A key general …
Structural Changes In U.S. Agricultural Production And Productivity, Jennifer S. James, Julian M. Alston, Philip G. Pardey, Matthew A. Andersen
Structural Changes In U.S. Agricultural Production And Productivity, Jennifer S. James, Julian M. Alston, Philip G. Pardey, Matthew A. Andersen
Agribusiness
The structure of U.S. agricultural production changed dramatically during the 20th Century. Major technological innovations transformed the relationship between agricultural inputs and outputs, and contributed to rapid increases in agricultural productivity. However, evidence is mounting that suggests we have entered a new era, with substantially lower rates of productivity growth. In this article, we examine trends and spatial patterns in agricultural input use, production of outputs, and productivity. We focus on productivity growth over the period 1949–2002, and find a statistically significant slowdown in productivity growth after 1990.
Economics And Policy Context For The Biological Management Of Soil Fertility (Bmsf) In Ethiopia, Habtamu T. Kassahun, Charles F. Nicholson, Dawit Solomon, Amy S. Collick, Tammo S. Steenhuis
Economics And Policy Context For The Biological Management Of Soil Fertility (Bmsf) In Ethiopia, Habtamu T. Kassahun, Charles F. Nicholson, Dawit Solomon, Amy S. Collick, Tammo S. Steenhuis
Agribusiness
Many developing countries implement programs and policies to increase or maintain soil fertility, with the objectives of increased crop yields and decreased poverty. However, few countries give emphasis to the biological management of soil fertility (BMSF) compared to more traditional approaches. Ethiopia emphasizes the use synthetic fertilizers to increase food security and reduce poverty, with little attention to BMSF. This paper examines the long term fertilizer consumption and agricultural productivity response trend and discusses the potential for BMSF to promote agricultural productivity and reduce poverty in Ethiopia. The paper also discusses the Economics and Policy Context for BMSF for the …
