Rehabilitation of Pasture Land through fencing
approaches

Rehabilitation of Pasture Land through fencing [塔吉克斯坦]

The approach demonstrates the effect and importance of rotational grazing by fencing certain areas of land in pasture areas as well as it demonstrates the rehabilitation process in comparison to the open space which is overgrazed. The approach involves mobilizing communities to observe the rehabilitation process by not grasing in …

2. SLM技术的说明

2.1 技术简介

技术定义:

In a pilot project, degraded pastureland near the settlement of Kasristskali was regenerated by introducing a fencing, mowing and grazing regime that favours the growth of forage plants instead of weeds and, where necessary, reseeding forage plants.

2.2 技术的详细说明

说明:

This showcase is part of the project "Applying Landscape and Sustainable Land Management (L-SLM) for mitigating land degradation and contributing to poverty reduction in rural areas", implemented by the Regional Environmental Center for the Caucasus (REC C).

The implementation site was selected by national experts together with stakeholders from the village. This site is located close to the settlement Kasristskali. It is community pastureland, which was abandoned and not maintained for many years. The site had been dominated by thistles and weeds before the intervention took place and was not suitable for grazing. 30% of the area was previously used to store manure and is rich in nutrients. To reclaim the pastureland for cattle, an area of 6.1 ha was mowed twice and equipped with an electric fence (two lines of electric wire and a solar-powered energizer brand Voss). This was done to regenerate the area so that a grazing regime could be introduced later. An electric fence was chosen because wood is not available in the area and a wire mesh fence would be more expensive. Furthermore, an electric fence is flexibly adjustable, which is essential for a rotational grazing system. It is important to remove the residues after the mowing to reduce the amount of weed seed. The time of mowing should be before the flowering of the most common weed species. An ongoing mowing and grazing regime was set up to favour fodder plants instead of weeds: Since the cows only eat the fodder plants and leave the weeds standing, the weeds have a clear advantage. To counteract this, the weeds are mowed, and fodder plants are sown. Mowing is needed for the first 2 years and after that, it is enough to control the quality of pastureland by a grazing system. For maintenance purposes, the area was cut once in early spring and a second time in summer. The evaluation in September, after the pastureland was recultivated, showed that the northern and eastern parts now have a grass and herb cover suitable for grazing, while the central, western and southern parts are still overgrown by weeds. This is due to the fact that these parts were very rich in nutrients from the very beginning and consisted exclusively of thistles. In order to improve the productivity of the site, it is recommended to cut the vegetation again in autumn, remove the residues, open the soil with a harrow and sow a pasture seed mixture adapted to the climatic conditions in February.

The local community farmers were involved in all activities. They were participated in development of local pasture management plan. The plan was approved by the community members and they are ready to follow the applied methodology and maintain the pastureland after the project completion. The farmers acknowledged the benefit from the proposed methodology and they invested to rehabilitate the additional area (6 ha) of pastureland with their own financial sources.

The 6.1 ha plot which was restored as pastureland with this technology is planned to be used as a paddock for alternating grazing between free-range and the paddock.

4.1 该技术的技术图纸

技术规范(与技术图纸相关):

The area on which the technology is applied is 6.1 ha. The paddock is on community rangeland and managed by the village people. It is located on a slightly north-oriented slope near the village. The area was used to store manure. The high nutrition values led to the enormous growth of weeds, especially thistles.

2. Third mowing and removal of hay September
注释:

The weed population is still very high. These are poisonous or spicy plant species which cannot be controlled by intensive grazing. To reduce the dominance of this weed, it is recommended to mow the entire area of 6.1 ha three times a year. The best time to mow is before the weed blossoms.

In the first two years, the forage harvest will be low, while the costs for erecting the fence and maintenance by mowing will be high. In the long run, unproductive land will be productive again. On the 6 ha, 6 to 12 tons of biomass per year can be expected (depending on rainfall in spring and summer). This is equivalent to 500-1000 USD/year.
