The UNESCO Lima office, through an agreement with the National Institute of Culture of Peru, is providing technical assistance for the development of heritage site management plans for the Pachacamac archeological complex and the Lines and Geoglyphs of Nasca and Pampas de Jumana. Such assistance requires the expertise of international specialists. The main objective of the work plans is to optimize material and human resources, thereby establishing priorities for halting site deterioration, reviving building and land use techniques, and raising community awareness about the historical and cultural meaning and importance of both sites.
