Coastal Zone
Wp 09 Regional case study TUNISIA
2Geographic and climatic characteristics
- The tunisian coastline spans 1300 km
- The southern part of the country is a part of
the Sahara -
- No big rivers exist except the Medjerdas
- 75 of the territory suffers from the aridity
- The northwestern part of the country gets between
500 and 1500 mm of precipitation per year - The dry season is too long
- In the south, precipitations dont exceed 150mm
(per year) - Except for the north, all the regions suffer
from the drought

- brackish water
12Problems
13Strategic trends of the tunisian policy
New water resources use has however become more
difficult. (The saturation of the use of such a
resource is expected to happen in 2015). As a
consequence, Tunisia will face a major challenge
the rational exploitation of an increasingly
scarce and expensive natural resource. This
challenge is linked to other constraints and
problems such as food security, unemployment and
regional imbalance.
14Problem of water use in the coastal zone
15Problem of water use in the coastal zone
16Investigation areas
- Tabarka
- Gulf of Hammamet
- Gulf of Gabes
17- Major problems
- Impact of big hydraulic structures on yhe coast
and on the coastal water areas - Water waste in the irrigation process
- Worsening of underground water quality (overuse
of pesticides in agriculture) - Tourism development
- Urban planification
Tabarka
18- Major problems
- Competition between agriculture and tourism as
far as water use is concerned - Overexploitation of underground water and sea
water intrusion - Extraordinary urban expansion
- Coastal disturbance of the coastal dynamics as a
consequence of touristic developments - Waste management
Hammamet
19- Major problems
- Competition between agriculture and tourism as
far as water use is concerned - Overexploitation of underground water and sea
water intrusion - Industrial pollution
- Waste management
Gabes
