  Climate Change and Wildfire Impacts in Southwest Forests and Woodlands (Climate Change and Variability in Southwest Ecosystems Series)

  Crimmins, Michael; Garfin, Gregg; Natural Resources & the Environment, School of (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2006-11)

  Southwest forests are complex systems that are influenced by climate variability. Wildfires naturally occur in these forests and woodlands, but with an increasing population, land management decisions are becoming more difficult. This publication is a result of discussions from the "Workshop on Climate Variability and Ecosystem Impacts" that was sponsored by UA Cooperative Extension in February 2005. It provides a summary of the current situation, a summary of climate change science for land management, and a brief description of suggested future research in climate science as it relates to forests and woodlands.

  Insects, Diseases, and Abiotic Disorders in Southwest Forests and Woodlands (Climate Change and Variability in Southwest Ecosystems Series)

  DeGomez, Tom; Garfin, Gregg; Natural Resources & the Environment, School of (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2006-08)

  Recent events in the forests of the Southwest have prompted scientists to consider the role of climate variability in insect and disease cycles. Over 70 million pine trees along with millions of other conifers died in 2002-03. Average temperature increases of 3°C enabled the MPB at those high elevations to achieve univoltine (having one generation per year) reproduction leading to previously unheard of outbreaks in white bark pine at high elevation sites in Idaho.Aspen defoliation in Arizona and New Mexico averaged ~ 20,375 acres from 1990 to 1997. A series of events has contributed to the decline of aspen since 1997.

  Sustainable Residential Development in the Southwest

  Donovan, Brian; College of Architecture, Planning and Landscape Architecture; Keith, Ladd; Iuliano, Joey (The University of Arizona, 2014-05-09)

  The goal of this study is to address the issues of sustainable residential housing in the United States, more specifically Tucson and the arid climate of the southwest. Until recent years the lack of awareness for sustainable practices has not damaged society, but currently, mankind’s impacts on the planet are unprecedented. As we progress into the future, acknowledgment of this problem needs to be addressed with innovation and solutions to secure a guaranteed healthy future for humanity, the species that humanity coexists with, and planet Earth. This study examines the principles of development that best produce sustainability and addresses building form and material use, solar orientation and shading, and land-use efficiency and governmental policy. These aspects of development are examined in detail by contrasting a typical University of Arizona rental development and a development that was constructed with sustainable consciousness for Tucson’s local population. Sustainable residential development is an issue that must begin on large scale with government policy and lawmakers, and end with individual home residencies and educated personal environmental decisions. The study found that, while there are many different aspects of sustainable development that are influenced by countless variables, a sense of cooperation among all phases of construction is the most effective way to guarantee a smooth transition into a more sustainable future.
