transportation in the urbanization sector is described as an "embodied" energy incorporated
in the manufacturing life cycle of the building materials.
The energy EF (EF_c) of the wilaya of Tipaza exceeds that of Algiers in two sectors, namely the
food sector, probably due to the important agricultural production in the wilaya of Tipaza, as
well as the water production sector, which could be associated with either greater production
or data availability.
The "Material" component, which ranks second in total EF contribution, is considerably more
important in the wilaya of Tipaza (49%) due to the large fisheries, crop, and livestock
production in the wilaya.
The last component, "EF_built," represents less than 1% of the total EF in both wilayas. This is
mainly due to the EF study model that assigns a low yield factor to this unproductive land,
although it is defined as a transformation of fertile surfaces. Second, due to a lack of data
describing these infrastructures, not all infrastructures have been included (e.g., public
facilities in the urbanization sector).
4.4. Demand for bioproductive areas
4.4.1. Estimation of biocapacity associated with the demand for surface
The assessment of the available bioproductive lands for the establishment and development
of the different activities and the absorption of the CO2 emissions that they generate in the
study area was based on local data. Indeed, the collected statistics describe the physical extent
of the lands used in each sector, namely cultivated surfaces (agricultural production),
grasslands (livestock), fishing areas (marine fishing and aquaculture area), forest surfaces
(wood production and CO2 sequestration area), and infrastructure area (dwelling and
individual houses projects) using the yield and equivalence factors of each type of land use
(Appendix 2).
The cartography of the fishing surfaces and the extent of land occupied infrastructures
provided input data to estimate the fishing, and the infrastructure BC, respectively. The figures
and define the fishing surfaces of the wilaya of Algiers and Tipaza. Similar to the figures
describing land use (figures 14, 15), th fishing grounds biocapacity has been estimated based,
first on a delimitation of the fishing zones of both wilays (figures 20, 21).
