Improving Spatio-Temporal Benefit Transfers For Pest Control By Generalist Predators In Cotton In The Southwestern Us, Ruscena Wiederholt, Kenneth J. Bagstad, Gary F. Mccracken, Jay E. Diffendorfer, John B. Loomis, Darius J. Semmens, Amy L. Russell, Chris Sansone, Kelsie Lasharr, Paul Cryan, Claudia Reynoso, Rodrigo A. Medellin, Laura Lopez-Hoffman

Amy L. Russell

Given rapid changes in agricultural practice, it is critical to understand how alterations in ecological, technological, and economic conditions over time and space impact ecosystem services in agroecosystems. Here, we present a benefit transfer approach to quantify cotton pest-control services provided by a generalist predator, the Mexican free-tailed bat (Tadarida brasiliensis mexicana), in the southwestern United States. We show that pest-control estimates derived using (1) a compound spatial-temporal model - which incorporates spatial and temporal variability in crop pest-control service values - are likely to exhibit less error than those derived using (2) a simple-spatial model (i.e., a model that …


Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers Jul 2016

Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers

William Edwards

A combine harvester econometric simulation model was developed with the goal of matching the combine forward speed to the maximum harvested net income per acre. The model considers the machinery management costs of owning a combine and platform header for harvesting wheat. A statistical Design of Experiment (DOE) was used to evaluate the model using tri-level variables; the medium values constituted the model base case. Of the 27 input variables, the optimum speed was significantly influenced by the crop area, G/MOG ratio, grain unit price, field yield, field efficiency, grain moisture content, probability of a working day in the post-optimum …

Site Assessment For Environmental Restoration, David A. Bainbridge Jan 2013

Site Assessment For Environmental Restoration, David A. Bainbridge

David A Bainbridge

Restoring degraded desert ecosystems is challenging but it can be done. The first key step is understanding the site history and understanding the disturbance and current site conditions. With this information the appropriate steps can be taken to improve the site ecosystem function and structure.

Rebound In Us Productive Sectors, Harry D. Saunders Jun 2011

Rebound In Us Productive Sectors, Harry D. Saunders

Harry D. Saunders

This presentation describes rebound measurements in the US economy, the dominance of "embedded energy" (production-side energy use), and the economic costs of polices to mitigate rebound effects.


An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders Apr 2011

An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders

Harry D. Saunders

This paper introduces a new decomposition of energy consumption to reveal the effects of consumer income levels on energy use. It concludes that the great bulk of energy consumption in the US is embedded in goods and services purchased by consumers and that this component of energy demand is growing more rapidly than direct use of energy by households owing to the preferences of high-income consumers. Significantly, this embedded component of energy demand has historically experienced large rebound magnitudes. The analysis also concludes that energy consumption is driven by more than just income level, with the lowest-income consumers using more …


Buried Clay Pot Irrigation, David A. Bainbridge Jan 2011

Buried Clay Pot Irrigation, David A. Bainbridge

Mother Earth "Speaks": Change Yourself, Change The World, Use The Archetypal Energy "Harmony" As A Guide, Carroy U. Ferguson Jun 2010

Mother Earth "Speaks": Change Yourself, Change The World, Use The Archetypal Energy "Harmony" As A Guide, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

In relation to the Cosmos, we all, as human beings, live on this tiny planet we call Earth, a planet that supports and sustains life, as we know it. There are many different kinds of people, plants, and animals functioning in harmony with soil, air, and water--all linked to one another in a complex web of life to form one Earth community. Unfortunately, we often take this miracle and ecosystem of life for granted. When, however, we take the ecosystem of life too much for granted, Mother Earth "speaks," reflecting imbalances and dis-harmonies. When Mother Earth "speaks," her message is …


Alternative "More Efficient" Irrigation Systems, David A. Bainbridge Jan 2010

Alternative "More Efficient" Irrigation Systems, David A. Bainbridge

True Cost Accounting For A Post-Autistic Economy, David A. Bainbridge Jan 2007

True Cost Accounting For A Post-Autistic Economy, David A. Bainbridge

David A Bainbridge

True cost accounting includes all environmental and social costs. If these are neglected the market fails. The critical link between ecosystem and humanity and the price of goods has been ignored at our peril.


Adding Ecological Considerations To Environmental Accounting, David A. Bainbridge Oct 2006

Adding Ecological Considerations To Environmental Accounting, David A. Bainbridge

David A Bainbridge

Environmental accounting has often neglected ecological costs. These are essential to complete a true cost accounting. Ecological costs are often very large and long term and if they are ignored the costs/benefits of projects are incorrectly calculated.


Acorn Use As Food, David A. Bainbridge Jan 2006

Acorn Use As Food, David A. Bainbridge

David A Bainbridge

The acorns from oaks (Quercus) and tan oaks (Lithocarpus) have been used as food for many thousands of years. They occur in the archaeological record of the early town sites in the Zagros Mountains, at Catal Hüyük (6000 BC), and oak trees were carefully inventoried by the Assyrians during the reign of Sargon II. In Europe, Asia, North Africa, the Mid-East, and North America, acorns were once a staple food. They are still a commercial food crop in several countries. Acorns are still harvested and used in several areas of the United States, most notably Southern Arizona and California. There …

Houses Of Straw, David A. Bainbridge

David A Bainbridge

Straw bale building offers high performance at a low cost. Bale building, developed on the grasslands of Nebraska at turn of the last century, has been rediscovered. High insulation values and high interior thermal mass make straw bales a good choice for passive solar design.

Self Reliant Agriculture For Arid Lands, David A. Bainbridge

David A Bainbridge

More than a billion people face the challenge of supporting themselves in the world's arid lands. Much can be improved by refining and adopting the best traditional practices and crops from around the world. The lessons learned can also help develop new and improved agronomic practices and crops.


Revegetating Desert Plant Communities, David A. Bainbridge Jan 1999

Revegetating Desert Plant Communities, David A. Bainbridge

David A Bainbridge

Desert revegetation is possible but not easy. Careful attention to plant production (root:shoot), site prep, planting, irrigation and aftercare can lead to good survival even under extreme desert conditions. Cost per survivor is a critical consideration.


Soil Pitting For Revegetation, David A. Bainbridge Jan 1999

Soil Pitting For Revegetation, David A. Bainbridge

Planning For Energy Conservation, David A. Bainbridge Jan 1976

Planning For Energy Conservation, David A. Bainbridge

David A Bainbridge

City planning can provide multiple benefits by considering energy conservation, solar orientation and local resource harvesting. Narrower streets reduce construction costs, reduce urban heat island impacts and are safer. Above ground drainage reduces costs and returns rainwater to groundwater.
