RESULTS AND DISCUSSION
3.Results and Discussion
3.1. Anthropogenic pressures assessment using satellite imagery
In order to assess the anthropogenic pressures at each studied site, the method suggested
by Lopez Y Royo et al. (2009) was applied and interpreted according to Garcia Marin (2013).
We applied two variants for land use estimation:
3.1.1. Lopez Y Royo et al. (2009): Land use only in the coastline (0.25km 2 )
The results obtained from this approach reveal that (03) sites are faced to low pressure
while the other sites are subject to moderate anthropogenic pressures.
The sites (CH), (AK) and (DLS) are under a low pressure, due to low urbanization over
the coastline, the natural aspect is most common in (CH) and agriculture is common in (AK)
and (DLS).
The sites (LP), (AB) and (PP) are under moderate pressure due to heavy urbanization
along the coastline.
Sites (BR) and (BSM) are under moderate pressure due to the agriculture along the
coastline.
3.1.2. Lopez Y Royo et al. (2009) and, adjusted in this study: land use over the 10km
The results obtained from this approach reveal that (02) sites (CH and DLS) are faced
with low pressure and the other sites are subject to moderate anthropogenic pressures.
The site (CH) is classified as low pressure. The land use is essentially natural, Oued Nador
is less than 10 km away and the Hadjout industrial zone is more than 10 km away, which is
considered moderate pressure. The fishing port of Tipaza exerts little pressure.
The site (DLS) is under low pressure, despite the proximity of the Oued Brika and the
Dellys fishing port, which exert little pressure on the station. Land use is mainly agricultural,
there is no industrial zone and no artificial structures on the site.
The site (AK) is under moderate pressure according to the Lopez Y Royo et al. (2009)
classification. The land use is mainly agricultural. As the site (CH) Oued Nador is less than
10km away and the industrial zone Hadjout is more than 10km away, this is considered as
moderate pressure. The fishing port of Tipaza exerts low pressure.
