The Sustainability Portal

Sustainable tools to meet fundamental human needs.W

Sustainability is expressed as meeting present environmental, social, and economic needs without compromising these factors for future generations A practice cannot be said to be 'sustainable for X years/generations.' The use of any span of time disqualifies the activity. Sustainability is for perpetuity.

Sustainability also means greater efficiency in resource use, ultimately giving benefits to economic growth and overcoming poverty, as well as health and quality of life.

Sustainable design and sustainable development are critical factors to sustainable living. Sustainable design encompasses the development of appropriate technology, which is a staple of sustainable living practices. Sustainable development in turn is the use of these technologies in infrastructure. Sustainable architecture (see Green building) and agriculture are the most common examples of this practice.

Sarah the hardest worker who is always chuggin' away.
CCAT yurt rainwater catchment. The long history of rainwater collection, can be traced (in recorded history) as far back as ancient times some 3,000 years ago (850 BC) if not even farther. The need for water is a basic human essential for maintaining life, without it, no civilization could have prospered. Rainwater collection in ancient Constantinople is one of the last megalithic structures of its kind.

The CCAT Rainwater Catchment Group consists of: Sean Colley, Matt de Young, Jessica Radtkey, Sarah Shimizu, and Tiesha Whittaker. Our project for ENGR 114 was to build a rainwater catchment system around the yurt at CCAT on campus at Humboldt State University. The purpose of the rainwater catchment system is to capture and store rainwater in a large storage drum for use to water plants on the CCAT grounds. Water is a resource that is always present around us but not always in an immediately useful form. Therefore, it is necessary that we use innovative and appropriate techniques to capture and transform the water that we have into a useful form of water for our needs.
