{mosgmap mapid=29|height=350px|zoomtype=small|showmaptype=true}

 

The area is located under sub-humid to semi-arid conditions; it is on the border of a cork oak forest, which means a quite stable environment. But, for many reasons, it is affected by desertification processes:

  • The cork oak forest is in a poor condition, due to overgrazing, wood cutting, forest diseases and climate change impacts on regeneration.
  • The cities' growth and the need for space for activities and transport.
  • The increasing pressure over the natural resources, namely soil and water posed by more intense agriculture systems, which are adopted to answer to the proximity of the Rabal-Salé urban market needs.
  • The soil is a made of a thick sandy leached horizon, which corresponds to old dunes developed in the region during a dry period of the upper Pleistocene; the humid conditions of the Holocene permitted the forest growth and the surface stabilisation; the current retreat of the forest creates again conditions for desertification, with the appearance of local dunes in the places affected.
  • The deficit of water and the competition between agriculture, urbanization and tourism on this resource.

Drivers, policies and laws http://www.desire-his.eu/index.php/en/sehoul-morocco/698-drivers-policies-and-laws- http://www.desire-his.eu/index.php/en/sehoul-morocco/698-drivers-policies-and-laws- The reasons for desertification and land degradation occurring can be environmental (for example due to the climate or soil conditions), economic, due to the actions of people or, most often, due to a combination of factors. The resulting degradation may be temporary or permanent.

 

To help understand this complex picture it can be helpful to think in terms the dominant socio-economic and environmental forces that are driving the process of land degradation. These place pressures on the land which have particular impacts. Human society may have already made responses to those impacts, or may have knowledge about how they could respond. Decisions about which responses to make may also be governed by a range of international, national or local policy regulations and agreements.

 

In the Sehoul study site, the same stakeholder workshop and questionnaires that were used to identify existing and potential response strategies (»Identifying strategies: Stakeholder workshop 1) also discussed and identified these driving forces; pressures; impacts; and the policy and regulation environment. This information was then used to inform the choice of »Field experiments and the scenarios used in »Simulated biophysical impact of remediation strategies and their financial viability.

Desertification risk assessment maps http://www.desire-his.eu/index.php/en/sehoul-morocco/699-desertification-risk-assessment-maps http://www.desire-his.eu/index.php/en/sehoul-morocco/699-desertification-risk-assessment-maps Source: extracted from Karavitis, C. Kosmas, C. et al. (submitted article) An expert system towards assessing desertification risk using indicators. Environmental Management

 

The procedure of calculation of Desertification Risk Index (DRI) in the Sehoul study sites started with the identification of the desertification process. These were found to be:

 

  • water erosion in forests,
  • water erosion in agricultural areas and
  • water erosion in pastures & shrubs.

 

For these processes, the Desertification Risk Assessment Tool needed data to calculate 161 indicators in 11 map units. This is because only the dominant degradation process is evaluated in each map unit; the number of indicators that is needed therefore differs between map units (Table 1). By using the WOCAT database, the required indicators were estimated and used as input to the Assessment Tool. Table 2 shows an example of the desertification risk calculation for Map Unit 3 (agriculture).

 

 

Table 1. Desertification risk calculation per Map Unit

Table 2. Desertification risk calculation for Map Unit 3 (agriculture)

The same procedure was repeated for all the other map units in the Sehoul study site and the DRI values calculated are shown in Table 1 and Map 1.

 

Map 1: Desertification risk index (DRI)

Map 2: Degree of land degradation (as assessed using the WOCAT mapping method)

The DRI map was compared with the WOCAT QM of the same area (Map 2). It was observed that even though the DRI and the WOCAT QM approaches produced maps sharing elements of a common data base, completely different calculation procedures have been applied (the RDI uses equations independently developed from another dataset and WOCAT has its own distinct methodology).  When the two maps are compared, it can be seen that the rate of degradation and the effectiveness of measures correspond closely to the DRI values, with the highest rate of degradation and the lowest measures effectiveness matching up to the highest values of DRI.

Introduction

The north west of Morocco has areas with extensive gullying of the agricultural lands. High pressure agriculture and overgrazing, combined with occasional heavy rainfall, causes severe land degradation. An additional problem is sedimentation in the drink water reservoirs downstream. For farmers in the area, annual crops for food production and livestock for immediate income is vital. The area characterized by a strong variation in seasonal rainfall from year to year. Ploughing is done at the first rains after September and with sufficient rainfall there will be a moderate harvest in February (mostly Wheat and Barley). If the crop fails it is used for fodder. For farmers in the area, annual rainfed crops for food production and livestock for immediate income is vital. There are no additional water sources and water conservation measures could help in this situation.

 

Desertification indices
The first area is abandoned and has heavy gully incision but analysis with high resolution remote sensing of gully change actually sows that the current erosion is not so high. This is well reflected in the erosion risk index of 2.92 (moderate risk). Vegetation cover is annual herbs and grasses. Water stress is seen as no risk (1.29) and there is a low risk of over grazing (2.38). The technique of gully stabilization with planting of Atriplex bushes and fencing cannot be tested directly but the added effect of an increase in cover and biomass can be simulated, while there is an assumed moderately effective capturing of runoff. Implementing this leads to a water erosion risk of 2.49 (low risk). Overgrazing reduces to low risk (1.62).

 

The second technique is minimum tillage on a rainfed cereal producing field on stony shallow soils. The slope angle is the same (20%). Under unmitigated circumstances the water erosion risk is moderate (2.78), a low overgrazing risk (2.38) and no water stress risk (1.29). Applying minimum tillage slightly lowers the erosion risk (still moderate: 2.56) and lowers also the water stress (1.17) and overgrazing risk (2.12).

Cereals on steep slopes, unmitigated Cereals, minimum tillage

 

Conclusions
The desertification risk assessment tool correctly classifies the risk levels of water erosion and overgrazing, but seems to underestimate the water stress risk (farmers have a difficult time gaining sufficient yield from rainfed agriculture in the area). The results are in line with the experimental results. Also when implementing the techniques the results are adequate although less pronounced than the experimental results. The techniques have to be translated to a change in primary variables first for this to happen (e.g. fencing means an increase in cover).

Identifying strategies: Stakeholder Workshop 1 http://www.desire-his.eu/index.php/en/sehoul-morocco/165-stakeholder-workshop-1-marmora-morocco http://www.desire-his.eu/index.php/en/sehoul-morocco/165-stakeholder-workshop-1-marmora-morocco A report on the results of the workshop "Land degradation and desertification - existing and potential prevention and mitigation strategies" held in Sehoul, Morocco from 19-21 June 2007

 

Field work and workshops on "existing and potential mitigation strategies against land degradation" were conducted with the objectives of sharing experience on current and potential problems and solutions regarding land degradation and desertification.

 

The aims are:

  • to identify existing and new strategies to prevent or mitigate land degradation and desertification.
  • to select a set of these identified strategies for further evaluation and documentation with the WOCAT methodology
  • to experiment with these strategies in some fields and make a follow-up with some required techniques of measurement.

 

The overall objective is to be able, after some years of experimentation to propose successful strategies for extension and improvement. The field work programmed is the monitoring of these techniques and approaches in order to determine their efficiency, both in terms of land degradation mitigation, social benefits and farm yield increase.

 

Main problems of degradation in the region

1. Inside the forest, the poor social situation of the population explains the rapid retreat and clearing of the vegetation cover, the non-regeneration of cork oak and the multiplication of poor species.

2. In the pastures, located on steep slopes, over-grazing leads to the degradation of the vegetation cover to the reduction of palatable species and to the development of rills and gullies.

3. In the cultivated area, the problems are more related to techniques of land use that are not adapted to the climate, to the weak soils and to the slope gradients

a. The decrease of soil moisture (due to the delayed and reduced precipitation in autumn or the early dryness in spring) leads to a reduction in the grain yield and in the biomass and represents an important factor of crisis both for agriculture and livestock.

b. The concentration, in some years, of extreme events with heavy rain during autumn on land which is still completely bare, produce very important runoff and soil erosion

 

c. The decrease of the piezometric level, due to over- exploitation of wells and to the increase of runoff in the fields.

 

Potential strategies

Some new techniques introduced during the last decades of the 20th centruy by some farmers were identified by the stakeholders who participated in the field interviews and the workshop, as potential strategies for a water and soil conservation approach.

 

Cork Oak Forests

Assisted cork oak plantation as a strategy for the sustainability of the forest.
