“…French expatriates, followed by Moroccan city dwellers, began to occupy the better and flatter areas for commercial cereal production, while the traditionally agro-pastoralist local population was forced to give up cultivation of the good-quality land on gentle slopes and cultivate the steeper slopes on its margins, instead. Population growth and contracts between local farmers and investors from the cities led to an increase in the number of sheep and goats, which added pressure on the natural resources of cultivated land as well as forest and shrubland 16 .…”

“…Land users generally preferred options that would not drastically change their current practices of cereal cropping and grazing. The final choice, therefore, included SLM technologies to improve grazing and cropland, namely plantation of fodder shrubs ( Atriplex halimus ) for gully rehabilitation on grazing slopes, permanent grass strips between annual cropping, and a combination of crop residues and minimum tillage 19 . The field experimentation of the latter is the example discussed in this paper.…”

“…Data gathered during the participatory process consisted of workshop reports 19 , 20 ; semi-structured interviews with ten stakeholders conducted in order to analyze the overall three-part methodology (as described in Schwilch et al 18 ); numerous conversations with farmers, technicians and researchers during field visits and meetings at administrative offices; participatory observation during stakeholder workshops and field trials; DESIRE project documents (posters at meetings, annual reports, etc. ); and WOCAT questionnaires filled in after trial implementation.…”

“…The improved cover on the fenced plots at the end of the dry season proved important in protecting the soil against the first rains in October-December, which are usually heavy and intense 16 . This observation is supported by the above soil moisture data.…”

In Sehoul, Morocco, the use of marginal land for agriculture became a necessity for the local population due to increased poverty and the occupation of the best land by new owners. Desertification poses an additional threat to agricultural production on marginal slopes, which are often stony and degraded. In a participatory process embedded in the EU DESIRE research project, potential sustainable land management measures were selected to address land degradation and desertification. Promising experiences with no-tillage practices elsewhere in Morocco had motivated the Moroccan government to promote conservation agriculture throughout the country. This combination of crop rotation, minimal soil disturbance and soil cover maintenance, however, had not yet been tested on sloping degraded land. Field trials of grazing enclosure combined with no or minimum tillage were conducted on the plots of two farmers, and trial results were analyzed based on stakeholders’ criteria. Results suggest that increased soil cover with barley residues improved rainwater use efficiency and yields only slightly, although soil water was generally enhanced. Soil moisture measurements revealed that no-tillage was favorable mainly at soil depths of 5 cm and in connection with low-rainfall events (<20 mm); under these circumstances, moisture content was generally higher under no-tillage than under conventional tillage. Moreover, stakeholder discussion confirmed that farmers in Sehoul remain primarily interested in animal husbandry and are reluctant to change the current grazing system. Implementation of conservation agriculture is thus challenged both by the degraded, sloping and stony nature of the land, and by the socio-economic circumstances in Sehoul.

“…Human activities can reinforce soil degradation through practices like overgrazing, intensification of agriculture, deforestation, urbanisation, etc. (Mahé et al 2013; Laouina et al 2010). These anthropic activities cause disturbances in the environment, which promotes erosion and degradation of the natural environment (Roose et al 1993).…”

Sidi Mohamed Ben Abdellah dam watershed is one of the most vulnerable areas of the risk of soil degradation due to its wide exposure, lithological heterogeneity and varying climatic factors. In this sense, the qualitative study of the spatial-temporal evaluation of ground-level occupancy from satellite visualisation data (acquired by the Landsat TM 5 and Landsat TM 8) device derives a land-use map that shows the areas at risk of degradation after the integration of a combination of multiple factors into a GIS geographic information system (climate, terrain, pedology, vegetation cover and human intervention (anti-erosive practice); The results require adaptive vision to better control the phenomenon, to reduce its severity in areas at high risk of soil degradation.
