描述

Planting fruit tree orchards to increase the stability of the steep loess soil slopes.

This technology involved the planting of several varieties of native fruit trees to help stabilise steep loess mountain slopes. Seven species of fruit trees were planted in seven different locations, in two watersheds within the district of Nurobod in Tajikistan. The locations were chosen as a result of a natural disaster workshop that identified the areas most susceptible to landslides.

In consultation with the Institute of Horticulture a fruit tree planting scheme was devised and using project money the identified area was enclosed with a wire perimeter fence. The fruit trees were planted along irrigation contours running at shallow angles parallel to the slope.

Purpose of the Technology: The best locations for planting the fruit trees were decided on via a participatory community workshop on natural disaster risk management.
During the workshop the community identified areas around the village that were considered high risk. A fruit tree planting scheme was implemented in these areas to help stabilise the slopes, reduce surface water run off and top soil erosion, and reduce the risk of landslides. As the trees grew they were intercropped with wheat and espercet.

Establishment / maintenance activities and inputs: Several 'at risk' areas were identifed within these workshops, therefore the project team had to assess the areas for suitability. Two of the main criteria used included the access to water and if there was sufficient depth of top soil to sustain a fruit orchard.
Once the area was decided upon, a Memorandum of Understanding (MoU) was signed with the particular land user. It was made clear to the community that the land was chosen based upon the decisions from the workshop and not because of any form of favouritism towards the land user. The MoU stated that the land user was responsible for the planting and maintenance of the orchards.
The Horticultural Institute devised a planting a scheme based upon the loaction and soil type. The implementation activities occurred in early spring. A continuos wire fence was erected around the area, and the fruit trees were planted at five metre intervals along a dug contour irrigation ditch. One kilo of organic fertiliser was applied to each tree and later in the season they were sprayed with pesticides.

Natural / human environment: Nurobod district is a mountainous area, with large tributaries flowing into the Vasht river. There are mass erosion processes at work, causing gullies and washing away the top soil. The previous civil war, compounded by harsh winters resulted in extensive clearance of the surrounding vegetation for fuel. These areas have became further degraded by over grazing on the remaining grass lands.
The local population suffers from high levels of labour migration of young men to Russia and resulting in a drain of knowledge and able bodied workers. This leaves the remaining families particulary vulnerable in this specific climate.

  • 计算的成本为:
  • 成本计算使用的货币:somoni
  • 汇率(换算为美元):1 美元 = 4.5 somoni
  • 雇用劳工的每日平均工资成本:25.00
影响成本的最重要因素
The main issue was the procurement of the fruit trees from a reliable credible source. Since the start of the project, land users purchased trees from local tree nurseries but the trees were of poor quality and some already had signs of disease. The scarity of natural resources, and the lack of controlled grazing means that wire fencing had to be used, This could only be purchased outside of the district and thus incurred high transport costs.

结论和吸取的教训

长处: 土地使用者的观点
  • It has made efficient use of the land that was previously used for grazing of livestock.
  • I have planted espercet in within the fence line, to improve my fodder production.
  • I learnt how to care for the trees in the training provided.

    How can they be sustained / enhanced? Further ongoing professional support for the land user would be beneficial.
长处: 编制者或其他关键资源人员的观点
  • It helped stabilise the soil and reduce the risk of mudslides.

    How can they be sustained / enhanced? Other identified areas could be planted with trees.
  • It helped to reduce the rates of surface water top soil erosion.

    How can they be sustained / enhanced? The area of land could be extended.
  • The fencing helped protect the technology from grazing livestock.

    How can they be sustained / enhanced? The fruit trees within the fence can be intercropped with perennial grasses or other crops.
  • It provides long term food and potential income for the land user.
弱点/缺点/风险: 土地使用者的观点如何克服
  • There are tree diseases in the district, which may spread to the fruit trees and many locals cannot afford the pesticides required to help prevent these. Pesticides could be provided by larger farms or cooperatives could be set up.
  • The livestock broke through the fence and ate some of the saplings. In some instances double fencing may be requried.
弱点/缺点/风险: 编制者或其他关键资源人员的观点如何克服
  • The areas identified to be stabilised do not always have access to water and therefore the technology is limited. Piped irrigation and drip irrigation techniques could be applied.
  • The land owner does not have any returns on the intial investment for a minimum of three years. Also they will have to pay tax on the land after three years. Some trees will not produce fruits for up to 12yrs. Loans or subsidies could be provided to the land user over this initial period of time.
