Front: An artistic impression of a 2-lane highway -a ribbon of asphalt stretching across a pristine terrain, towards a brighter future, enabling access to many without disturbance to any. Back: In the absence of highways, vehicular movement still goes on, causing severe long term degradation of vast swathes of land. Film-strip: The storyline between the two situations -social isolation, ecological values, traditional livelihoods, intergenerational equity, and the role of remote sensing, GIS and an understanding of scale in facilitating the right balance between them -is what this thesis is about.
