The amount of waste produced by this urban population and to be landfilled is estimated at 20,600 T/year in 2014, which justifies implementing of a new controlled landfill in the study area, respecting all socio-environmental standards. This population currently totals 309,000 inhabitants and will reach 393,000 by 2032 whether the region’s socio-economic development projects are implemented. The urban population lives essentially in the areas of the cities and urban centers of Tarmigte, Amerzgane, Kourkoda, Tachakouchte, Timjijte, Anzal, Tabourahte, Ait Ben Haddou, Timdline, Telouet, Ighrem Nougdal, Agouim, Tidili, Skoura, Toundoute, Iminoulaoune, and Ghessate et Idelsane. Waste management in the study area is performed in a very crude and conventional form, except in the city of Ouarzazate, and does not take into account the improvement of the standard of living and work of the workers and rag pickers and does not take into consideration the approach to environmental protection in which Morocco has been engaged. Efficient waste management systems that can provide reliable services are needed to confront the increasing amounts of solid waste, as many current systems fail to satisfy the needs. This expansion of urban growth endangers sustainable urbanization and has resulted in many challenges. Effective management of municipal solid waste (MSW) is a major challenge for local authorities and planners due to the rapid industrialization, population increase and land scarcity. Solid waste management is a matter of great international concern from an environmental, morphological, and socio-economic viewpoint. These sites are located very close to the province’s waste hubs, which helps reduce the cost of transporting waste to the new landfill. In the field, five sites have been provisionally selected, but only sites D and B have been given higher priority because of their geographical location, large surface area, geological imperviousness, zero risks, better soil quality, distance from any protection zone, any water point or hydrographic network, and their accessibility by provincial roads. The rasters of all the criteria were prepared, processed, and overlaid in the GIS environment by assigning each parameter its weight according to its importance. Eleven criteria were selected, including distance to protected areas, wind direction, subsurface geology, lineament density, distance to surface water (river systems and dams), soil quality, distance to roads, elevation, and slope. For these reasons, this study was conducted to identify appropriate landfill sites and waste transfer centers using geographic information systems (GIS) and remote sensing coupled with multi-criteria evaluation techniques such as AHP. Indeed, this landfill is considered to be located in the wrong place according to the results of our study it does not meet all the main socio-environmental criteria. Over time, urban extensions tend to move towards the site of the landfill following the development plans of the city, which influences the environmental life and health of the new population. Moreover, in 2009, a controlled landfill was established near the city of Ouarzazate. The most typical landfills are located in small villages that resemble illegal dumps or dark areas close to the inhabitants. Currently, more than 42% of the total population does not have access to a controlled landfill that meets all the socio-environmental criteria defined by Law 28-00 and its implementing regulations. The province of Ouarzazate has a population of 10,744 and is divided into 17 communes (15 rural communes and 2 urban communes), the majority of which have a population of less than 2000 people.
