Monitoring of conservation technologies and approaches

Author: Mohamed Ouessar, Institut des Régions Arides, Tunisia

 

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.
