News on WADIS-MAR activities

In these last months several actions were carried out within WADIS-MAR project for gradually achieving the results of each projected activity:

Activity 1 - Project Management and coordination

Activity 1.2 – Administrative and financial setting up and arrangement
Launching of some tender procurement in Algeria

Activity 2 – Integrated Water and Agricultural Management (IWAM) System design

A 2.1 – Existing data collection and geodatabase realization

3D reconstruction of Tunisian geological surfaces
This activity started at the beginning of  2013 for the intervention site of Tunisia and it is in progress.  These are the steps already carried out: examination of stratigraphic logs for the study area and implementation of geographic, geological, hydro-geological and chemical informations within geo-database; digitalization of geological chart and location of stratigraphic logs; chronostratigraphic interpretation of geological data; constructing of geological cross sections for building the tri-dimension model of Trias surface in order to identify the lower Triassic aquifer geometry.

Land Use/Land Cover (LULC) classification of Algeria site
Land cover classes were obtained throughout the interpretation of remote sensed data, in particular Landsat satellite image from June 2011, corroborating other available spatial data with agricultural calendars, statistics and bibliographical data used for a major precision of class assignment. The methodological and classification approach was the one proposed by CORINE land cover, which allowed us to delineate a land cover legend and interpretation keys and variables, adapted to the local context.
We have proceeded to the establishment of validation points/training areas in order to have a basic validation of the ground – truth data, aiming for a further multi – temporal analysis of the land cover distribution, given the availability of remotely sensed data such as Landsat 5, 7 and 8, allowing the achievement of an optimal level of knowledge of the territory and providing the methodological foundation for project monitoring activities. 

A 2.2 – Field data survey
In September 2013 a technical monitoring visit in Medenine was carried out at the following sites which have been selected for the pilot agronomic demonstration activities: Bedoui (Délégation Sidi Makhlouf), Megarine (Délégation Médenine Nord), Ksar el Hallouf (Délégation Beni Kheddache), Chaabet El Anze (Délégation Beni Kheddache).
Other selected sites where to install the artificial aquifer recharge intervention have been visited: Oued Ennageb / Koutine and wadi Arniane

A2.3 – Public Participatory GIS - PPGIS
On 13th and 14th June  2013 two PPGIS workshops were held in Médenine (Tunisie) involving farmers of three selected Oum Zessar sub-catchments (Chaabet El Anaz – upstream, Loudayette – middle-stream, Oued Moussa – downstream areas) that are actually practicing rainfed farming systems as well as farmers from three irrigated sites (Bedoui, Megarine and Ksar el Hallouf) where WADIS-MAR agronomic activities are being carrying out.
Aims of the workshops were:

  • to share experiences between farmers that use different farming management systems;
  • to update the action plan matrix for each sub-catchment (with a better definition of numbers of water harvesting systems to implement, time, costs, etc.);
  • to select three representative farmers (for the upstream, middle-stream and downstream areas) with whom to implement additional demonstration agronomic activities focused on the improvement of the water supplementary irrigation management for olive trees in summer.

A2.4 – Final design
Some proposals for the artificial groundwater recharge in Tunisia and Algeria sites have been developed. They should be discussed with with partners in next technical missions for evaluation of costs, feasibility, etc..

Activity 3 - IWAM System construction

A 3.3 - Realization and rehabilitation of existing irrigation infrastructures and A 3.4 - Implementation of best agricultural practices
Implementation of agronomic interventions for water harvesting techniques, soil erosion control, cropping diversification and water saving strategies started in the identified four sites in Tunisia:

  • 2 december 2013: steering committee meeting at tunis (tunisia);
  • December 2013: agriculture field mission at biskra (algeria);
  • december 2013: equipment purchasing (algeria)
