The first is how to adequately define topographicst ructure morphol- ogically or hydrologically, and the second is how to design algorithms for the defined topographic structure.

Conceptualizing Rural Development in the World Today Since the start of the Industrial Revolution and colonial times, agricultural change has been driven by the pull towards cities; the emergence of new livelihoods; and, in some cases, by famine, war and landlessness resulting from population growth, civil conflict, land consolidation by legal and illegal means; and, of course, by opening of agricultural lands in forests, wetlands or other natural areas.
