Distinguishing Land Change From Natural Variability And Uncertainty In Central Mexico With Modis Evi, Trmm Precipitation, And Modis Lst Data, Zachary Christman, John Rogan, J. Ronald Eastman, B. L. Turner Ii

Zachary Christman

Precipitation and temperature enact variable influences on vegetation, impacting the type and condition of land cover, as well as the assessment of change over broad landscapes. Separating the influence of vegetative variability independent and discrete land cover change remains a major challenge to landscape change assessments. The heterogeneous Lerma-Chapala-Santiago watershed of central Mexico exemplifies both natural and anthropogenic forces enacting variability and change on the landscape. This study employed a time series of Enhanced Vegetation Index (EVI) composites from the Moderate Resolution Imaging Spectoradiometer (MODIS) for 2001–2007 and per-pixel multiple linear regressions in order to model changes in EVI as …

Greener And Safer: Some Potential Choices For Interior Materials For Buildings Undergoing Construction Or Renovation, Nellie J. Brown

Nellie J. Brown, MS., C.I.H.

Executive Summary

What is good for the environment is not automatically safer for workers, but it should be possible to make choices to that are both “greener” and “safer”.

This guide aims to help you to be “greener and safer” by planning ahead – prevention through design by making good choices of materials. Sometimes choices are interconnected and may have multiple benefits. USCDC/NIOSH has piloted a program, in collaboration with OSHA, AIHA, and many others, called “prevention through design” (PtD). The concept of PtD can be defined as: Addressing occupational safety and health needs in the design process to prevent …
