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.


Container Plants For Desert Restoration, David A. Bainbridge Jan 2013

Container Plants For Desert Restoration, David A. Bainbridge

David A Bainbridge

Container planting is essential for most desert restoration work because direct seeding is rarely successful. The containers best suited for desert planting are often taller (deeper) to facilitate root development. Fertilizer management, inoculation, irrigation and pruning can be used to maximize root growth with minimal shoot development.


Buried Clay Pipe Irrigation, David A. Bainbridge Dec 2012

Buried Clay Pipe Irrigation, David A. Bainbridge

David A Bainbridge

The buried clay pipe method of irrigation is one of the most efficient systems known and is ideal for gardeners and small farmers. Buried clay pipe irrigation uses a buried, unglazed clay pipe filled with water to provide controlled irrigation to plants as the water seeps out through the clay wall at a rate that is influenced by the plant's water use. It has been used for more than one hundred years.This auto-regulation leads to very high efficiency--considerably better than drip irrigation and many times better than conventional surface irrigation. This also reduces weeds, increases yields, and can speed maturity …


Wick Irrigation, David A. Bainbridge Jan 2012

Wick Irrigation, David A. Bainbridge

David A Bainbridge

Super Efficient Irrigation With Buried Clay Pots, David A. Bainbridge

David A Bainbridge

Buried clay pot irrigation was first described in an agricultural extension bulletin in China more than 2000 years ago. The clay pot provides demand responsive irrigation at very high efficiency. Clay pot irrigation can be 5-10 times more efficient than conventional irrigation. It is being used more widely in Asia, Africa, Latin American and the US.


Porous Capsule Irrigation, David A. Bainbridge Dec 2011

Porous Capsule Irrigation, David A. Bainbridge

David A Bainbridge

Porous capsule irrigation is a modern adaptation of buried clay pot irrigation. Research in Brazil and Mexico has demonstrated its value in improving water use efficiency. Porous capsules are more easily integrated in an irrigation network than buried clay pots.


Buried Clay Pot Irrigation, David A. Bainbridge Jan 2011

Buried Clay Pot Irrigation, David A. Bainbridge

David A Bainbridge

Buried clay pot irrigation was first described in Chinese texts from more than 2000 years ago. It uses a porous clay pot to provide demand responsive irrigation. Efficiency is often 3-10 times conventional surface irrigation.

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 …

Ecocomposite Materials, David A. Bainbridge Jan 2001

Ecocomposite Materials, David A. Bainbridge

David A Bainbridge

If we are wise we can make a transition to the Age of Ecocomposites with virtually no pollution. Ecocomposite materials are those made with natural fibers and resins and can be produced in sustainable agro-industrial ecosystems. These materials can reused, recycled or returned to nature by grinding, composting, biological breakdown, or benign solvents. Historical use and recent rediscovery of these materials has suggested the many advantages (and challenges) using these materials offer to designers and engineers.
