Abstract
The desert oasis is a wetland agro-ecosystem more and more under pressure. This trend threatens the oasis ecosystem services (ES) and then the wellbeing of the local population. In order to quantify this trend in Middle Draa Valley, South of Morocco, the monetary values for a selection of ES have been estimated. In this chapter, the economic values of 28 provisioning ES in 2014 was examined and next compared with the economic values of 2009. These values were standardized to US$ per hectare per year. The total value of the studied provisioning ES in 2014 was found to be 8658.3 US$/ha/year for the arable area (26000ha) and 150 US$/ha/year for the whole Middle Draa Valley (1500000ha). Comparing these findings with the data of 2009, a slight increase of $1245.7 (in 26000ha) and $21.5 US$/ha/year (the whole area) was detected in the period 2009-2014.
