Chicken tractors
The name "chicken tractor" is somewhat misleading, since no conventional motorized devices are used. A chicken tractor is little more than an open-bottom cage for chickens, which is light enough to be moved on the ground from location to another.

The chickens live in the chicken tractor and scratch, eat, and defecate on the ground surface. This process turns over the shallow surface, hence the 'tractor' reference. As the surface is sufficiently worked by the chickens, the tractor is moved to another space, repeating the process. The consumption of plants, seeds, and insects reduces plant growth and insect population, and the defecation nourishes the soil. Conventional chicken houses produce a volume of chicken waste with very high Nitrate concentration, which will burn many plants if used directly and therefore must be composted. The chicken tractor eliminates these handling and processing needs.

A chicken tractor will work on any flat surface with a substrate that supports plants and insects. Its main benefits are that it is a means of having free-range chickens and its attended benefits, but with better control/protection of the chickens. Moving it around permits more localized vegetation management, and keeps chickens out of gardens. Read more...

Kiva's straw bale greenhouse
An alternative or natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or renewable resources, as well as those that, while recycled or salvaged, produce healthy living environments and maintain indoor air quality. Natural building tends to rely on human labor, more than technology. As Michael G. Smith observes, it depends on "local ecology, geology and climate; on the character of the particular building site, and on the needs and personalities of the builders and users."

The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort, health or aesthetics. To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. The use of rapidly renewable materials is increasingly a focus. In addition to relying on natural building materials, the emphasis on the architectural design is heightened. The orientation of a building, the utilization of local climate and site conditions, the emphasis on natural ventilation through design, fundamentally lessen operational costs and positively impact the environmental. Building compactly and minimizing the ecological footprint is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse.
