During the year 2010, biophysical surveys were carried out by five implementing institution in different locations shown in the following map:


Results of the surveys were presented, in a formal workshop at NCARE during 15-16 September of 2010, to stakeholders and discussed among experts, local communities, PMU and scientific communities to identify the bolded lines for the community action plan (CAP). Needs of the local communities, particularly livestock owners, were also discussed and debated during the official international workshop on 23rd of September 2010, under the patronage of UNCC and JNFP. The main findings of both workshops were the urgent need to put BRP into action and to implement the CAP of BRP. The immediate needs of local communities were identified as water, forage, and veterinary services for livestock.

 The main biophysical findings of BRP baseline studies can be summarized as following:

  1.         The run-off Hammada and Marab ecosystems, if given the opportunity with proper intervention, have the potential to promote growth and production of the existing vegetation regardless of the prolonged history of destructive grazing and other irrational uses.
  2.       In spite of the good rainfall in 2009/2010, the reported values of vegetation cover were low which reflected the severe degradation of rangelands due to prolonged history of irrational uses (destructive grazing, cultivation, uprooting of woody plants…) and very poor soil seed bank.
  3.        The poor condition of vegetation indicates that natural recovery of degraded rangelands will last for many years before achieving substantial improvements.  Although the “Roadmap” is in favor for the use of the natural recovery approach, the biophysical intervention approach, i.e. plantation of fodder shrubs within micro-catchment water harvesting techniques, seems more appropriate to improve forage productivity within relatively a short time. 
  4.       Frequent mobility of pastoralists with their tents and flocks, seeking for feed and water for their livestock, makes any attempt to protect and manage the designated lands during the initial stage of restoration a difficult task.  Collaboration between local communities and The Royal Department for Environmental Protection (Rangers) is essential for the development of a framework for a sustainable protection of the targeted demonstration sites. Moreover, the construction of stock watering ponds and the proper distribution of these ponds on a geographical area will minimize the livestock and traffic movement and therefore minimize the land degradation.
  5.       The physical and chemical properties of soils indicated that some of the range sites in targeted areas are not suited for cultivation.  Capped and shallow soils of these sites increase the incidence of surface run-off on one hand and reduce water storage capacity on the other hand resulting in low productivity of vegetation biomass.
  6.        The flat range sites with a slope gradient less than 5% are not suitable for the micro-catchment intervention to plant fodder shrubs.  However, there are sizable areas in some demonstration sites and the targeted watersheds suitable for this type of intervention. 
  7.        Poor vegetation cover and low production of biomass were reflected in low values of grazing capacity and thus highlighted the need for many years to improve the capacity of targeted areas.
  8.       Veterinary services are lacking in these sites which adversely affected productivity of communities’ livestock.
