2.1 Short description of the Technology

Definition of the Technology:

Thistles invaded massively into village pasture land at 1800m elevation in the Caucasus. By cutting the thistles with a motor-cutter the cover of thistles have been reduced.

2.2 Detailed description of the Technology

Description:

The technology was applied in flat sub-alpine pasture land at an elevation of about 1800 m in the village of Shenako in the Tusheti Protected Landscape, Georgia. Precipitation is 750-900mm and mean annual temperature is 2-4°C. Thistles (Cirsium sp.) were invading especially in those sections of the pasture that are rich in nutrients and have medium soil water content. This site conditions can be found mainly at the valley bottom.
There are no big machines available in this mountain villages. So the removal was done by motor-cutters. In this particular case STIHL petrol brush cutters were used with a 3 blade bush knife.
The removal of the thistles, which were covering up to 20% of the pasture land will increase the productivity of valuable fodder grass and herbs. The thistles are growing up to 1m height and taking up significant amount of nutrients from the soil and are shading other grass and herbs in their neighborhood. Because of their spices they are not eaten by cows or sheep, while the grazing pressure is increasing on the remaining grass and herb species. This leads to positive selection of thistles and a permanent increase of the thistles number and biomass in comparison to the high quality fodder plants.
The thistles have been cut in mid-June/beginning of July just at the begin of blossom. At this stage, the thistles mobilized most of the nutrients from their root system and spent them in leaf and blossom biomass. By cutting the thistles at this time, the highest impact on the nutrient balance can be reached and no new seeds will be produced in this year. It was observed, that the thistles have been eaten by the livestock when it was cut and dried up.
The motor brush cutter increases significantly the speed of cutting the thistles compared to hand scythe. The thistle has a powerful root system and is re-sprouting from the roots within the same summer. So it is important to repeat the cutting 2-3 times a year and to continue several years until the amount of thistles is permanently reduced.
The reduction of thistles will give more space, nutrients and moisture to other fodder plants and increase the productivity of the pasture land.
The challenge is the coordination of the work load within the users of the community pasture land. It needs a (written) agreement to share the workload for pasture maintenance between the families according to their number of livestock.

Comments (type of project, etc.):

The weed control was funded and applied within a GEF Projected coordinated by REC Caucasus ("Applying Landscape and Sustainable Land Management (L-SLM) for mitigating land degradation and contributing to poverty reduction in rural areas"). It can be assumed, that there have been community based regulation on pasture maintenance before the Soviet period, but this regulations have not been re-established after this period.

• rainfed

3.5 SLM group to which the Technology belongs

• pastoralism and grazing land management

3.6 SLM measures comprising the Technology

management measures

• M5: Control/ change of species composition

Comments:

The technology aims to reduce the amount of thistles in the species composition of the pasture.

3.7 Main types of land degradation addressed by the Technology

biological degradation

• Bs: quality and species composition/ diversity decline

Comments:

The degradation of the pastures is driven by the spreading of thistles. This process leads to a reduction of plant-diversity (shading) and fodder production.

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:

• reduce land degradation

Comments:

Cutting thistles is an measure for weed-control and reduces the risk of overgrazing be increasing the available area and amount of fodder plants.

6.1 On-site impacts the Technology has shown

Socio-economic impacts

Production

Specify assessment of on-site impacts (measurements):

The impact of the weed control on the productivity will increase when the vitality of thistles will be further reduced by frequently repetition of cutting.

6.2 Off-site impacts the Technology has shown

Specify assessment of off-site impacts (measurements):

The dissemination of thistles seeds in the surrounding areas is reduced, when thistles are cut before blossom.

6.3 Exposure and sensitivity of the Technology to gradual climate change and climate-related extremes/ disasters (as perceived by land users)

Comments:

These sites at the valley bottom have high soil moisture content and did not show significant impact of climate change in the last decade.

6.4 Cost-benefit analysis

How do the benefits compare with the establishment costs (from land users’ perspective)?

How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?

Comments:

The productivity of the pastureland is 2-3t/ha per year. The removal of thistles can lead on the long term to an increase of fodder by 20% (400-600kg/ha per year). This is equivalent to 15-20 hay-bales a 3 USD (total 45-60 USD/ha and year). The amount of time for cutting the thistles and the needed patrol will decrease when during the next years so a positive balance between investment and return is expected.

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?

• 0-10%

Comments:

It will take 2-3 years to show the full success of the measure. It needs a to negotiate new regulations on village level to agree on how to share the workload for pasture maintenance between the households according to the number of cattle.
