Editing Tunis (section)

=== Sectors ===
The economic structure of Tunis, as well as that of the country, is overwhelmingly [[tertiary industry]]. The city is the largest financial center in the country hosting the headquarters of 65% of financial companies – while the industrial sectors are gradually declining in importance.<ref name="STRAT"/>  However the secondary industry is still very represented and Tunis hosts 85% of industrial establishments in the four governorates, with a trend towards the spread of specialized industrial zones in the suburbs.

Primary industry such as agriculture, however, is active in specialized agricultural areas in the suburbs, particularly in the wine and olive oil industries. The generally flat terrain and the two main rivers in Tunisia, the [[Medjerda]] to the north and the [[Milian]] to the south, the soils are fertile.<ref>{{harvp|Sebag|1998|p=13}}</ref>  Tunis has several large plains, the most productive are in [[Ariana]] and [[La Soukra]] (north), the plain of [[Manouba]] (west) and the plain of [[Mornag]] (south). In addition, groundwater is easily accessible through the drilling of deep wells, providing water for the different agriculture crops. The soils are heavy and contain limestone in the north but are lighter and sandy containing [[clay]] in the south.<ref>{{harvp|Sebag|1998|p=40}}</ref>  There is much diversification in the municipality of Tunis, with [[Durum]] grown in Manouba, Olives and olive oil in Ariana and Mornag, wine (Mornag), and fruit, vegetable and [[legume]]s are grown in all regions.<ref>{{harvp|Sebag|1998|pp=41–42}}</ref>
