By 2050 more than a third of Tucson Arizona's days will have a heat index of 104 degrees or greater if current excessive energy use behavior continues (Climate Central 2016). During the 20th century, the water table of Tucson's aquifer dropped 200' because of excessive water use. (Arizona-Sonora Desert Museum, 2013)
Our communities and buildings so far have not incorporated regenerative sustainability, the sustainable design and construction practices that could help avoid these problems.
Campus Farm Green, a new-home community in Tucson, is working to change that. "The Green" explores a new paradigm for developing regeneratively sustainable homes and neighborhoods that goes beyond reducing harm to the environment to helping to heal the environment. The Green has been designed to generate and return to the grid more electricity than it uses, and capture and return to the ground more water than it buys from the water utility. It does this while providing homes that can be sold for a profit at market prices.
This paper describes the challenges and solutions of the sustainably regenerative design and construction that is at the heart of The Green.

For waste management in Asunción, Paraguay to improve, so too must the rate of public recycling participation. However, due to minimal public waste management infrastructure, it is up to individual citizens and the private sector to develop recycling solutions in the city. One social enterprise called Soluciones Ecológicas (SE) has deployed a system of drop-off recycling stations called ecopuntos, which allow residents to deposit their paper and cardboard, plastic, and aluminum. For SE to maximize the use of its ecopuntos, it must understand the perceived barriers to, and benefits of, their use. To identify these barriers and benefits, a doer on-doer survey based on the behavioral determinants outlined in the Designing for Behavior Change Framework was distributed among Asunción residents. Results showed that perceived self-efficacy, perceived social norms, and perceived positive consequences – as well as age – were influential in shaping ecopunto use. Other determinants such as perceived negative consequences, access, and universal motivators were significant predictors of gender and age. SE and other institutions looking to improve recycling can use these results to design effective behavior change interventions.
