  • Field works between Jeffara Zone and Dahar Zone, including: Geology field Trip; data collection (structural geological data and a hydrogeological data); Collection of data for new geological interpretation
  • Second learning event of CADWAGO project (June 2014). The Tunisian part of the SWIM - Wadis Mar project (www.wadismar.eu) has become one of the case studies of the Cadwago project (www.cadwago.net). Cadwago (Climate change adaptation and water governance - reconciling food security, renewable energy and the provision of multiple ecosystem services) aims to improve water governance by developing a more robust knowledge base and enhancing capacity to adapt to climate change.
  • Field work (Oum Zessar area): a- Land Cover Ground-truth; b- Secondary data collection (i.e. socio-economical data); c- Adjustment of interpretation keys; d- Areas affected by salinity: ground observation and e- In situ spectral measurements
  • Acquisition of remotely sensed data intended for the preparation of maps of the evolution over time of land cover (land degradation and desertification phenomena in arid and semi – arid areas throughout Remote Sensing techniques based on the soil salinity severity identification, mapping and dynamics analysis methods as well as the comparison of remote spectral signatures from satellite images with direct spectral  measurements of salt –affected areas)
  • Collection of salty soils samples for hyperspectral remote sensing analysis
  • Finalization  of the artificial aquifer recharge intervention design (including the final costs estimation, the materials selection). This will be done in collaboration with CRDA
  • Proposal for the artificial groundwater recharge for the Trias aquifer in the Oum Zessar watershed and selection of intervention areas. The artificial recharge system so defined, includes recharge basins, vadose-zone wells, also called dry wells and recharge wells with recharge chambers
  • Preparation of a tentative hydrogeological and agricultural intervention plan. 3 micro-catchments of Oum Zessour watershed have been defined for intervention: Chaabet El Anaz site (up-stream area), Loudayette site (mid-stream area), Oued Moussa site (Down-stream area).
  • A Public Participatory GIS (PPGIS) workshop in Medenine involving beneficiary farmers of the identified micro-catchments and other stakeholders (representatives of local authorities, researchers, professionals, representative of civil society, NGO)
  • Preparation of a tentative hydrogeological and agricultural intervention plan. 3 micro-catchments of Oum Zessour watershed have been defined for intervention: Chaabet El Anaz site (up-stream area), Loudayette site (mid-stream area), Oued Moussa site (Down-stream area)
