2.1 Short description of the Technology

Definition of the Technology:

Rehabilitation of a gullied slope and gully control, by plantation of Atriplex halimus fodder shrubs.

2.2 Detailed description of the Technology

Description:

The experimental plot, with a size of 5000m², corresponds to an old fallow field and strongly gullied slope. The gullies are parallel and start around the middle of the slope. They extend by retreat of the gully heads upslope. Each gully is 2 to 4 m large and 1 to 2 m deep and up to 120 m long. Downslope, the gullies lose their depth and deposit fans composed of material eroded upstream, before they join the channel of Hannanet, which has the tendency to incise its bed (more than 4 m deep) inside colluvial deposits made of sand, clay and beds of pebbles. The plot was planted with shrubs of Atriplex halimus, and enclosed with a fence since April 2009. Planting was organised in strips 6 m apart, with the objective of stabilizing the gullies and restoring biodiversity. Planting density is about 760 shrubs/ha, with a rate of success of about 89.5%. Owing to late plantation in spring it was irrigated every 20 days during the summer months. It is planned to open it again to grazing 2.5 years after its plantation.

Purpose of the Technology: The objective of the fencing to prevent encroachment of animals is to improve the vegetation cover through reduction of loss through grazing and reduced compaction of the soil. This improves biodiversity and also provides richer and more varied grass fodder in addition to the fodder from the shrubs. The improved cover density retains water in the soil and reduces runoff. The aim is to reduce the catchment area of the gullies, and the amount of water collected in order to progressively diminish the gullies.

Establishment / maintenance activities and inputs: Several phases were undertaken in the establishment of this experimental plot: The plants were obtained from a nursery in the Beni Mellal region (from the Forest authority). The second activity was the preparation of holes (760 holes of 40x40x40cm) and the establishment of a wire fence around the plot, in order to ensure no grazing during the first 2 years. After planting the shrubs, irrigation was necessary for the first few months during the dry season.

Natural / human environment: The climate is semi-arid with around 450 mm of rain annually. The topography consists of a plateau, incised by channels, with short tributaries extending into the Grou valley. The slope angle is between 10 and 50 %. The soils on the slope are often not developed. The thick colluvium, which is made of erodible reddish sand and clay, explains the depth and width of the gullies. The economy relies on a system based on cereals and grazing. The income of this system is low because of the extensive character and the reduction of yield due to degradation. Many changes are occurring, such as changes in land cover and in emigration, land abandonment and increased links to urban activities.

2.6 Date of implementation

If precise year is not known, indicate approximate date:

• less than 10 years ago (recently)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• during experiments/ research
• through projects/ external interventions

Comments (type of project, etc.):

The technology was introduced as an experiment, in the context of a research project which started 5 years ago; it was recommended by the local stakeholders during participatory process. The experiment tries to confirm the ability to plantation of fodder shrubs in a fenced plot to increase biomass and biodiversity and reduce the erosion process of gullying.

3.2 Current land use type(s) where the Technology is applied

Land use mixed within the same land unit:

Yes

Specify mixed land use (crops/ grazing/ trees):

• Agro-pastoralism (incl. integrated crop-livestock)

Comments:

Major land use problems (compiler’s opinion): Retreat and degradation of the vegetation cover, degradation of soil quality, development of signs of water erosion, namely rills and on some slopes gullies with rapid extension. Progressive expansion of abandoned lands not recolonized by vegetation, which create patches of desertified land in the area.

Major land use problems (land users’ perception): Decrease in yield, decrease in the availability of water and of its level in wells.

Semi-nomadism / pastoralism: Small movements to the nearby forest

Forest products and services: fuelwood, grazing / browsing, other forest products / uses (honey, medical, etc.)

Future (final) land use (after implementation of SLM Technology): Grazing land: Gi: Intensive grazing/ fodder production

Livestock density: 25-50 LU /km2

3.6 SLM measures comprising the Technology

Comments:

Main measures: vegetative measures

Secondary measures: management measures

Type of vegetative measures: aligned: -contour

3.7 Main types of land degradation addressed by the Technology

Comments:

Main type of degradation addressed: Wg: gully erosion / gullying

Main causes of degradation: overgrazing (The animal pressure increased recently, due to association between the local inhabitants and investors from the city), disturbance of water cycle (infiltration / runoff) (The overgrazing on degraded soils leads to decrease of permebility and then less infiltration to the water table), other human induced causes (specify) (The degraded lands are abandoned and this leads to the continuous extension and more deep incisions of gullies), change of seasonal rainfall (The irregularity of rain is a factor of degradation), Heavy / extreme rainfall (intensity/amounts) (The intensity of rain can be a major factor of impact on the soils), land tenure (the extensive grazing is based on the principle of free displacement of flocks), poverty / wealth (The social level of population explains the need to over-exploitation of natural resources), education, access to knowledge and support services (Lack of conscience), attractiveness of cities (The proximity of cities explains the attirance of those spaces on the population (opportunities for jobs))

Secondary causes of degradation: soil management (The cereal use during years degraded the soils which became poor with a weak yield and fragile against processes of erosion), deforestation / removal of natural vegetation (incl. forest fires) (The clearing of forest was flollowed by a crop use which doesn't offer to the soils the same protection and doesn't feed them with organic matter), droughts (The dry years have an occurrence of 1/2 and can be a factor of abandon of lands), population pressure (This factor is not very important in this area because the trend is for a stability of the population)
