Scope and Intensity of Land-Use Modification Across Arizona (October 2017)

GIS dataset that depicts intensity and spatial distribution of prior human modification on non-tribal Arizona lands. Based on inspection of 2010 aerial imagery and reference datasets, prior human modification estimated within one square mile hexagons in following categories: 0%, 1-5%, 5-25%, 25-50, and >50%. Dataset can be used to inform conservation and infrastructure planning.

A Place for Human Modification and Intactness Data in Regional Mitigation (October 2017)

This report describes a human modification dataset for non-tribal lands in Arizona that can be used for conservation and infrastructure planning processes. The report describes methodology used to develop dataset, summarizes intensity and spatial distribution of prior human modification across the state, presents a case study for use in regional mitigation planning of an infrastructure project, and compares dataset to other models of landscape intactness. Dataset is available for download on this website.

Sustainable Water Management in the Southwestern United States: Reality or Rhetoric? (July 2010)

Published in PLoS ONE, this study used four scenarios to explore the potential effects of alternative growth and water management strategies on river flows. Under the base population projection, we found that rivers in seven of the 18 study watersheds could be dewatered due to municipal demand. Our approach provides a low-cost method to identify where alternative water and growth management strategies may have the most impact, and demonstrates that such strategies can maintain a continued water supply for both people and the environment.
