2.1 Short description of the Technology

Definition of the Technology:

Contour planting of olive trees with crops, legumes and vegetables intercropping

2.2 Detailed description of the Technology

Description:

On gentle slopes of the Sehoul municipality, heavy or prolonged rainfall causes runoff and erosion on cultivated lands cleared at the beginning of the 20th century. In the last 10 years, in some plots, land users have started to implement contour plantations separated by intercropping strips with annual crops. Only the immediate tree surroundings involve harvesting and storing rainwater and runoff. No additional water harvesting structure has been built. A fence around the plot prevents livestock from entering.

Purpose of the Technology: The economic objective of the technology is to improve income, because cultivation of cereals only gives low yields (500-600 kg/ha). Olive trees can provide an attractive yield and can be an alternative to crops especially during drought. As the olive tree is considered a revered tree, the technology is also beneficial from a social viewpoint. Environmental objectives include surface protection against erosion as well as the maintenance and improvement of soil fertility.

Establishment / maintenance activities and inputs: To implement the change, a boundary of barbed wire (Chabkka) or cactus to form a natural hedge is installed in order to prevent livestock intrusion. Plantation work includes breaking up the soil, digging holes along the contour and planting the trees. Animal manure and chemical fertilizers are used as inputs. Weeding, pesticide application and manual watering are required regularly to support tree growth. As a drip-irrigation technique, watering cans with perforations are left to drop water continuously until the cans are empty.

Natural / human environment: The plantations are on a fragile substrate of marl underlying Plio-Quaternary and loamy-stony deposits with more than 40 cm of fersialitic and sandy soil on low-angled slopes (<10 %). The climate is Mediterranean with a semi-arid trend. The socio-economic environment is characterised by a medium-density population (10-50 persons/km2) and scattered homesteads. The traditional production system (cultivation of cereals and extensive breeding) is dominant, as well as the use of traditional techniques and practices. Tillage is performed using animal traction.

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

The technology has been implemented by the Development of rainfed agriculture project (Projet de Mise en Valeur Bour, MVB) in Shoul. Later, land users have adopted this technology voluntarily and some of them have even been trained about the technology.

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation
• create beneficial economic impact

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

Land use mixed within the same land unit:

Yes

Comments:

major cash crop: Cereals and legumes cultivation
major food crop: Wheat and barley
olive trees on stripes

Major land use problems (compiler’s opinion): Irregular rainfall and drought, lack of surface water and depth of the groundwater table are major environmental problems. Excessive runoff causes gullying in the event of exceptional heavy rainfall. All fields on slopes are subject to soil loss because of sheet erosion, especially in early autumn, when lands are bare and without a plant cover due to summer grazing. Gully erosion also results from concentrated runoff from bare ground upslope, especially on steep slopes. There is a lack of support from the authorities and agricultural services and insufficient knowledge about water conservation. Technologies for surface water harvesting do not exist.

Future (final) land use (after implementation of SLM Technology): Mixed: Mf: Agroforestry

Type of cropping system and major crops comments: Cultivation system consists of olive trees on stripes and annual intercropping
