2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Crops rotation: cereals / fodder legumes (lupin), with a biennial crop rotation

2.2 Detailed description of the Technology

Description:

Farming is the main activity of the Sehoul population. In the past, it was based on subsistence cultivation and especially on extensive breeding outside the farm. The cultivation practice mostly applied was barley monoculture. Nowadays, crop rotation is more and more diversified (use of other cereal species and mainly legumes). Because of land degradation on forest pasture, farmers increasingly use their farm land for fodder or legume production such as oats and lupin. White lupins were introduced in the region during the colonial era (1912-1956), through individual initiatives with no external support. The advantages of lupin cultivation are its ability to grow on poor and stony soils and, like other leguminous crops, it does not need nitrogen fertilizers because of its ability to fix nitrogen from the air, which reduces the costs. Additionally, lupin does not require much water (a minimum of 350 mm per year is sufficient). Considering the importance of pastoral activity in the production system of the Sehoul district, this technology meets the expectations of the population as follows. Firstly, there is improvement of fodder production. Lupin is a leguminous crop which can be eaten by ruminants either as green fodder or as grain. Secondly, there is soil improvement through a better structure, an increased soil organic matter content and better nitrogen retention that can be used for the next cultivation. Thirdly, there is a better soil cover because lupin is an invasive plant with efficient roots for finding nutrients, which allows its cultivation on poor soils.
The lupin cultivation technique consists of the following: spreading the seed in October-November, and possibly until mid-December. Early sowing shows good yields, because cold temperatures cause early blossoming. For white lupin, sowing density is about 100 kg/ha. Ploughing (20-25 cm deep ploughing is sufficient) to bury the seed is performed with a swing plough and two mules on slopes, and with a metallic plough or a tractor on plains. No weeding or fertilization activities are required because of the lupin's good nitrogen fixation capacity. However, an additional second or third ploughing can improve the harvest, but is often constrained by a lack of means. A first grazing is allowed in March but afterwards it is left so that it can recover again. Harvesting is done manually with sickles in August and residues are grazed again. Seed production is 8-10 quintals/ha, biomass is 3000 kg/ha.
This technology is applied on plateau margins with steep slopes, where traditional small-scale land use includes predominantly winter crop cultivations (wheat and barley) and secondary spring food cultivations (broad beans, chickpea, maize). On the plateau, bigger and better maintained farms perform irrigated cultivation with ground water. The cork oak forests are coveted as pasture land and firewood source and therefore they are regarded as important for their free natural fodder resources. Pasture land (except forests) covers a small area (12% of the Sehoul area) because of land appropriation and cultivation. Only the collective and the fallow lands are now used as pasture lands and generally show important and alarming degradation processes.

biological degradation

  • Bq: quantity/ biomass decline
Comments:

Main type of degradation addressed: Bq: quantity / biomass decline

Secondary types of degradation addressed: Cn: fertility decline and reduced organic matter content

Main causes of degradation: deforestation / removal of natural vegetation (incl. forest fires) (Total clearing activities causes soil degradation problems), other natural causes (avalanches, volcanic eruptions, mud flows, highly susceptible natural resources, extreme topography, etc.) specify (soil fragility because of the very thin topsoil surface layer and the low organic matter content), poverty / wealth

Secondary causes of degradation: crop management (annual, perennial, tree/shrub) (Crop monoculture, which replaced the forest, cannot provide the necessary soil cover. The inadequate fertility management has also led to a decrease in the organic matter), overgrazing (After the reduction of pasture lands because of the cultivation area extension, the animal pressure has increased and pasture activities were reduced.), population pressure, education, access to knowledge and support services

negative

Long-term returns:

positive

How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:

neutral/ balanced

Long-term returns:

slightly positive

Comments:

Rotation benefits can only appear in the long-term, after the amortization of implementation expenses.

6.5 Adoption of the Technology

Of all those who have adopted the Technology, how many have did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 90-100%
Comments:

100% of land user families have adopted the Technology without any external material support

40 land user families have adopted the Technology without any external material support

There is no trend towards spontaneous adoption of the Technology

Comments on adoption trend: This technology is in decline because of the use of fertilizers which allow a crop/crop rotation and because of the increased seeds prices. As for food leguminous plants, this cultivation requires the mobilization of the family labour, nowadays not available taking into account the factor of emigration.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Better soil fertility management

How can they be sustained / enhanced? Make demonstrations for the benefit of the population
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Maintenance of the soil fertility

How can they be sustained / enhanced? Encourage the crop rotation by subsidy of the administration
Low-cost technology

How can they be sustained / enhanced? Make demonstrations for the benefit of the population
Technology not very demanding in SWC knowledge

How can they be sustained / enhanced? Technical support to use the technology better

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Reduce the use of crop rotation and move the animals away from the exploited land occupied by cultivations throughout the year. Replace legumes by fodder crop on the open-field
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
Erosion risks for the spring cultivations (maize), because the soil is bare during a high rainfall period. Introduce a catch crop cultivation before the legumes or maize cultivation in order to cover the soil during the heavy rains. Mulching can also be done.
Very demanding in family and animals workforce Mechanization
