2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
CONSTRUCTION OF FENCES TO KEEP WILD BOAR OFF PASTURE LAND
2.2 Detailed description of the Technology
Description:
ẗhe regulations implemented by the Pollino national park to protect the wild fauna have led to large numbers of wild boar in the local area. Numbers of wild boar have also increased because of breeding with non-native species (a Hungarian strain) on the part of hunting associations. Numbers have increased so much that currently these animals have even reached rural areas destined for pasture, livestock farming and cultivation. To protect crops and pastures more fences have been built. Typically these fences are constructed out of pales made from local wood and galvanised iron netting.
Purpose of the Technology: Protection of pasture land and cropland
Establishment / maintenance activities and inputs: The construction of fences requires an initial investment in order to buy the wooden pales and iron netting. Generally the pales come from local woods, often from the farm itself, and are felled and prepared by local farmers who also usually construct the fences themselves. The height of the fences ranges from 1m to 1.20
Natural / human environment: Production methods are characterised by a medium level of mechanisation (only the most demanding operations are carried out using mechanical means), the production system is essentially mixed, a small part is destined for personal consumption whilst the bulk of production is destined for local markets. The property is predominantly privately owned but also includes some public land, especially in the case of pasture land. Most farms in the area are livestock farms whilst the agricultural component is destined exclusively for private consumption. The area is partially included in two bordered national parks, i.e. Pollino national park and val d’agri national park. This peculiar situation creates a very natural environment allowing the presence of many wild species.

2.7 Introduction of the Technology
Specify how the Technology was introduced:
- through land users' innovation
3. Classification of the SLM Technology
3.2 Current land use type(s) where the Technology is applied
Cropland
- Annual cropping
Grazing land
Extensive grazing land:
- Semi-nomadism/ pastoralism
- Ranching
Main animal species and products:
Main animal species ranching: Sheep/Goats/Cow
Comments:
Major land use problems (compiler’s opinion): The wild boar tend to dig into the ground in search of food and, in doing so, leave soil open to processes of erosion and permanently degrade grass cover.
Major land use problems (land users’ perception): Severe damage to grass cover and crops
Semi-nomadism / pastoralism: Shepherds use the area for summer grazing and move downhill in winter
Mixed: (eg agro-pastoralism, silvo-pastoralism): A reduced number of farmers cultivate their field for fodder and pastures
Grazingland comments: Sheep and goats are the most valuable livestock
Type of grazing system comments: Sheep and goats are the most valuable livestock

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view | How can they be overcome? |
---|---|
The only disadvantage is the high initial cost of building fences which is, however, partly mitigated by the possibility to use the fences also as boundary marker dividing one property from another. |
