Without water, the land has no value"
Arid and semi-arid lands develop when climatic conditions create water limitations and the water lost through evaporation exceeds the water gained from precipitation. Severe water limitations and climatic extremes make these arid and semi-arid regions very dependent on careful and conservative water management. Traditional practices that use only gravity to distribute water in these environments have been used for thousands of years, but have been little studied and are under-appreciated. These gravity-based canal systems are known as acequia (Spanish) and secondary and lateral ditches are called laterales, linderos, sangrias, or venitas. The head gates that divide and control water flow are called compuertas. The workers who build and maintain these systems are known as acequieros. Acequias are called séquia (Catalan), acéquia (Portugese) and saia (Sicilian). The common name acequia is from the Arabic as-saqiya, meaning water conduit.

Adapted from the Yemeni-Sabean language, predating the Arab arrival. In Yemen these irrigation systems are now called ma'aayeen. In Oman they are falaj, in Arabic literally 'to divide.' For thousands of years acequias have relied on the force of gravity for the collection, conduction, distribution, recollection, and discharge of water in farming systems. This sophisticated community-based irrigation was brought to Spain by farm families arriving from the Arabian Peninsula (Yemen, Oman, Syria and Egypt).1 The antecedents also included the irrigation practices used in other arid regions of the Roman Empire.2 The acequias were adopted and refined in southern Spain, particularly Andalusia, Castilla, and Valencia during the Moorish occupation3 and brought to the Americas in the 1500s. The key factors are gravity flow and community management. Many acequias are still in use around the world including the United States (particularly in Colorado,

Steve and I did a book on Sustainable Agriculture for California together and I spent so much time in the library many people assumed I worked there. This training and experience highlighted the value of data bases and the importance of training students to use them more effectively. I have used the following assignment in most classes for the last ten years, modified to suit the topic and the changes in technology. It has become increasingly important as students fall prey to the Google/Yahoo search strategy. This often leads to very weak sources of information. The power of the data bases now available to students for free is astonishing and I try to impress upon them the importance of becoming an effective researcher. This is new for most students we get (both domestic and international), because they have not been taught good research habits, critical thinking, and effective research paper writing. The good news is they are as smart as ever and pick this up pretty quickly. Most manage to bring research papers up from an average of 60/100 at the first draft to high 80s or even 90s by the third or fourth draft. This paper includes a typical research assignment and the paper grading criteria for the research paper.

This helps students understand the foundations and principles of passive solar architecture and sustainable building. Test data collected by students can provide clear lessons on the options that provide improved comfort, more healthful conditions and increase productivity while improving management of energy and materials. The goal of this workshop is to help students develop a better understanding of the practice of passive solar architecture and testing design options using data loggers and statistics.

Building components are often tested in a very artificial environment instead of the chaotic multi-directional movement experienced in a real earthquake. These simplified tests are very expensive, running into the tens or hundreds of thousands of dollars. The recently completed test facility at the University of California, San Diego cost $10 million dollars. Testing on this innovative facility will be very expensive, but will provide new insight and understanding. This cost is far out of reach of universities and engineering test labs in most countries where seismic risks are high or extremely high. New methods for low cost testing of earthquake proofing for non-scalable materials such as adobe, straw clay, straw bales, and stone are also urgently needed. Improved testing for infrastructure is also needed. The mobile test sysem described here may offer an alternative at low cost.

Developing true cost accounting is essential. Growing interest and work in this field is inspiring and will make a difference. Even rudimentary calculations of the external costs and benefits will help lead to change. Transactions between consumers, companies, organizations and communities will be more sustainable and lead to a more positive future. This is particularly important for energy. Many side effects, like nitrogen pollution, are very serious problems -- currently rarely counted. Climate change is noted but rarely fully costed.

The olla (buried clay pot or pitcher) method of irrigation is one of the most efficient systems known and is ideal for gardeners and small farmers and can be used in a patio container. I first learned about it in a Chinese agricultural text from 2000 years ago. Olla irrigation uses a buried, unglazed clay pot 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. Remarkable reduction in water use (90%) has been achieved with concurrent yield increases.

Many time scales begin with the Stone Age, which led to the Bronze, Iron, Steel, and Plastic ages as innovations and improvements in refining, smelting, manufacturing and science made these materials available at reasonable prices. In the 1980's the Composite Age began, represented at its extremes by the Stealth bomber and the sun powered Solar Challenger. A composite material combines two or more materials that work together to improve overall performance of the material. Innovative developments and market forces now herald the beginning of the Ecocomposite Age using biological fibers and natural or synthetic matrix materials (Bainbridge, 2001). Ecocomposites can be very strong and selections can be made for ultimate strength, elastic modulus, fracture resistance or impact resistance. Ecocomposites are also more environmentally friendly and less hazardous to human health. The ideal ecocomposite material will be made of all natural materials that are non-toxic and biodegradable and renewable. The term ecocomposite is also used for materials that are made of natural materials and recycled materials, or made entirely of recycled materials.

Facing very high costs for imported charcoal they developed innovative building designs that utilized the sun for heating and microclimate resources for cooling. The importance of the sun led to the development of the first solar cities and solar rights. Passive solar design was also included in many other traditional buildings systems, from China to India, the tropics to northern climes. But these lessons were forgotten in the dark Ages and more recently, the fossil fool age.

The energy crises of 1973 and 1979 triggered Federal and private investment in solar design, including passive solar systems. Up to this point the elements of passive solar architecture had emerged as orientation, south facing windows, solar control to limit overheating in summer, and ventilation. Using these alone it was possible to reduce building energy use dramatically but more could be done if this was seen as a systems problem where cooling was equally important.

Passive solar design strategies can improve the comfort and performance of buildings in any climate. In many areas these buildings can be built a cost equal to conventional buildings. Passive solar design can provide comfort and security from the low deserts of Arizona and California to the icy winters of Alaska. These buildings save money for owners and improve security, and also reduce peak power demand. The energy and financial savings over the lifetime of these naturally heated and cooled buildings can help improve the outlook for California and for the world by reducing greenhouse gas emissions and providing security in an ever more vulnerable world

A mother well starts the qanat and then an underground canal set at a minimal pitch carries the water for many kilometers until it comes to the surface and is used. The qanats also provide cool air for buildings and energy to turn small grain mills. Thousands of qanats are still in use around the world.

Water seeps from the groundwater through the porous rock and subsoil into the well during dry times. When the pool level rises during the rainy season water from the well helps recharge the groundwater. Stepwells are most common in arid or semi-arid regions where the rainfall varies dramatically by season and year and the depth to groundwater rises and falls. They allow users to get water close to home at any time. As the water level declines it is clear to users that conservation is needed.

Special interest groups have spent millions of dollars to confuse these issues when concerns are raised. Billions of dollars are made by ignoring health and environmental impacts and the disasters that lead to costly public spending. Many of these problems will persist for generations yet unborn. True cost accounting is needed and will be essential in crafting a more sustainable future.
