 Techniques monitored The selected monitoring sites represent the main encountered problems in the region namely: water scarcity and rangeland degradation. 
- Water harvesting techniques (jessour and tabias) are used for the improvement of water content of soil and thus evapotranspiration of plants and trees.
 
- Replenishment of groundwater aquifers are ensured through the recharge structures (gabion check dams and recharge wells).
 
- Rangeland degradation is cured using the rangeland resting techniques.

Monitoring activities Meteorology 
- Meteo measurements
 
- Rainfall recording
 
- Outflow at subwatershed level
 
- Piezometric levels
 
 
Repeated measurements 
- Soil moisture gravimetric method,
 
- Leaf resistance using a porometer
 
- Plant cover, species diversity/density,biomass, range production.
 
 
Agronomical activities by stakeholder 
- Dates and type of tillage
 
- harvest and other inputs
 
- Animal practices
 
 
Yield assessment 
- Total yield in kg/ha
 
- General yield  quality or herd/grazing quality assessment
 
- General impression by stakeholders

Preliminary results 
- The implementation of the SLM technologies have been conducted by a close collaboration with all stockholders who worked effectively together from the phase of planning, through the field execution and the finial evaluation of the completed works.
 
- As farmers are already well acquainted with the technologies, the implementation was relatively a smooth exercise.
 
- If the simplification of the monitored parameters  to the farmers is absolutely necessary to gain their implication, the involvement of the developments agents is rather an easier task.
 
- The last year was exceptionally dry (˜ 100 mm). Therefore no major agricultural activities have been carried out.

Main difficulties encountered  
- The highly variable rainfall regime and the slow development of local species, typical of drylands, require more patience from the researchers and the other stakeholders.
 
- Generally, poor farmers are more interested in immediate returns rather than long term benefits.
 
- Very few stakeholders do care about global impacts (off site land degradation, climate change, etc) as their concern about household living priorities.
 
- Parallel large development programs with consistent budgets, undermine the effects of small scale research projects with relatively very limited financial resources.
