2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

This technology consists of (a) ploughing the soil, (b) sowing the plants usually vetch or oat or in combination in November and (c) grazing the growing plants during spring. The main purpose of this technology is to increase the produced palatable biomass in a grazing land in which the biomass production is very low under natural conditions.

2.2 Detailed description of the Technology

Description:

The technology is applied on semi-arid areas of Asteroussia Mountains of Crete used as grazing land with an annual rainfall between 501-750 mm. These areas are usually highly degraded, characterized by steep mountainous slopes (31-60%). This technology was mainly found in shallow (depth: 21-50 cm), moderately fine textured soils which moderate concentrations of soil organic matter (1-3%). The stock breeders in the region use a special regime for transferring livestock grazing rights from the communities to individuals. Nowadays the off farm income of breeders is between 10-50% of their total income.

Looking back, in the early 1950s to the 1980s the Asteroussia Mountains were a livestock-specialized area. Livestock production was based on controlled summer grazing in the mountains and overwintering in the lowlands. After the early 1960s, the area increasingly felt the impact of agricultural mechanization and - by consequence - excessive under-occupied rural labor force, which led to disproportionate out-migration from the area. In areas where limited natural capital was already fully utilized, such as in Asteroussia Mountains, further growth through increasing flocks was only possible by importing fodder. In a parallel, increasing intensification of agriculture in the nearby Messara plain limited the opportunities for the tradition of transhumance. Throughout the mid-1980s–2010s the economy remained livestock-dominated but the population decline continued. However, the presence of foreign migrants offering cheap labor from the early 1990s onwards contributed to keep many farms active.

Coming back to the technology, it consists of: (a) clearing natural vegetation, usually perennial shrubs accompanied with annual plants including mainly grasses, (b) sowing of high value palatable plant species for animals such as oat, vetch, etc. during winter, (c) allowing plants to grow adequately, and (d) grazing by the animals mainly during spring for a period of about one month, and (e) keeping the land bare until next wet cultivation period starts. The purpose is to increase the available biomass for the grazing animals in areas of low productivity of natural vegetation suitable for them. The major activities consists of clearing the land, plowing usually by a bulldoze type tractor, sowing the seeds and adding appropriate fertilizers. However, the establishment of this technology may face problems in clearing natural vegetation, if the existing Greek institutional framework does not allow doing it. Land degradation and desertification are very frequent processes in semi-arid areas and both processes have been enhanced in the last decades by climatic variations and human activities. The EU-funded research project DESIRE in Eastern and Western Europe, Latin America, Africa and Asia have identified soil erosion, forest fires, and overgrazing among the most important causes of land degradation. The main benefit of this technology therefore is the increase in the amount of high quality palatable biomass for the grazing animals in degraded lands. Land users like this technology, if the number of animals is high, as without the technology they face problems of feeding them. However, such an action increases the cost of animal production such as milk. In addition, soil erosion problems are expected since land remains bare for some period of the year especially after sowing the plants.

Comments and further specifications on biodiversity:

The most important land cover types are schlerophyllous vegetation, transitional woodland-shrubs and sparsely vegetated areas covering the 88% of the total area. The rest of the area is covered by agricultural crops, mainly olive trees and cereals. The dominant woody plant species in the area include Olea sylvestris, Olea Europa, Salix alba (along watercourses), Pyrus amygdaliformis, Prunus webbii, Thymus capitatus, Salvia triloba, Flomis lanata, Flomis fruticosa, Sarcopoterium spinosum, Calicotome vilosa, Scilla maritime, Asfodelus aestivus, Euphorbia characias. Overgrazing coupled with frequent fires shaped the vegetation pattern in the area determining the predominance of the less palatable fire-tolerant plant species. The above-mentioned state of biodiversity existed before clearing the land even in degraded areas.
