  • This article explores the land-cover effects of state-sponsored modernization efforts in the semiarid Godwar region of Rajasthan, India. Using household production information and the discourse of state planners, the research explores the land
  • covers that result from agricultural intensification, biodiversity preservation and resource conservation. Through these efforts, state planners have attempted to partition those land uses seen as social from those seen as natural and enforce a modernist
  • purification of land covers. Despite these efforts, hybride and impure land covers have proliferated across the landscape. The results of analysis is that our landscapes have never been modern.

  • The AA. report on a field experiment studying the effects of different densities of roughness elements on sediment transport and foredune profile development. Reed stems are planted as a surrogate for vegetation at the frontal side of the foredune
  • . Plots are covered with a regular pattern of bundles of reed stems, in 3 different densities. Profiles through the plots are monitored over a period of one year. The aim of the experiment is to study profile development for several vegetation densities
