2. SLM技术的说明

2.1 技术简介

技术定义:

Reforestation of the Tugai floodplain ecosystem with reed stands, poplars, djigda, and tamarisk thickets to strengthen the river bank area along the Pyanj river.

2.2 技术的详细说明

说明:

Reforestation works are being carried out in an area of 18.2 km2 in four demarcated zones each measuring 4.55 km2. ACTED and CAREC have entered into labour agreements with household representatives of villages near the riparian area to carry out the plantation of seedlings and bushes. 520 household representatives will plant a variety of 150,000 seedlings and bushes in the floodplain area (prone to flooding).

Reforestation works will help to reinforce the river bank area and protect it against potentially large scale floods. It will also diminish the effect of river bank erosion caused by flood waters. The activity will also protect the natural ecosystem in the target area and provide greater security for both the animal and human habitat. As a secondary purpose the reforestation works will also encourage local communities to be more aware of, and to hopefully motivate them to address some of the serious environmental and socio-economical problems affecting them.

The area was preselected by an expert as an area that was a degraded Tugai floodplain forest ecosystem. The area was assessed to ensure it still maintained a Tugai ecosystem. The extensive area was broken into smaller manageable parts of 3.5 h.a., these areas were then allocated to Jamoats who then further reassigned the responsibility to households. The next step is the development of a planting plan and schedule that includes fruit trees, timber and thickets.

The seedlings are obtained from the National Park area in collaboration with the state forestry department. The households are taught basic planting techniques, and supervised during the planting from November to March. A maintenance plan was established to ensure the upkeep of the ecosystem including watering, composting, and pruning.

The issue was that the Pyanj river was encroaching towards villages and cultivated lands that are essential to the livelihood of the local inhabitants. There is a lack of natural resources and increasing pressure on the available land for subsistence farming.

3. SLM技术的分类

3.1 该技术的主要目的

  • 减少、预防、恢复土地退化
  • 保护生态系统
  • 保持/提高生物多样性

3.2 应用该技术的当前土地利用类型

森林/林地

森林/林地

  • Poor natural Tugai forest ecosystem
产品和服务:
  • 木材
  • 薪材
  • 自然保持/保护
注释:

Major land use problems (compiler’s opinion): The seasonal flooding has resulted in severe river bank and soil erosion that has caused a reduction in the area of cultivated land, which provides an increasing threat to the village settlements. An increasing population is also adding to pressures on the limited land available, so threatening the livelihoods of local farmer households.
Major land use problems (land users’ perception): Local people highlight a lack of income and energy sources that lead them to cut down trees and vegetation for use as fuel and animal feed.
Problems / comments regarding forest use: It is a degraded forest with little economic value.
Future (final) land use (after implementation of SLM Technology): Forests / woodlands: Fp: Plantations, afforestations

6.7 该技术的优点/长处/机会

土地使用者眼中的长处/优势/机会
Land users are happy that their land is protected and that they are being provided with added incentives through food for work and the construction of orchards and nurseries.
编制者或其他关键资源人员认为的长处/优势/机会
The Tugai ecosystem acts as natural mitigation system for large scale flooding in the target area. It does not rely on heavy structural maintenance such as artificial dikes or gabions.
Involves representatives of target communities in the mitigation works. It gives them a sense of ownership towards the activities.

6.8 技术的弱点/缺点/风险及其克服方法

编制者或其他关键资源人员认为的弱点/缺点/风险 如何克服它们?
Mitigation is not an instant and obvious return, so the benefits are less obvious. Land users need to be educated about the environmental and risk mitigation benefits of the project. Practical demonstrations are advisable. Furthermore, as there is no instant benefit it is also advisable to offer land users incentives (e.g. food for work and construction of household orchards and nurseries).
Maintenance of the reforested area requires labour post-reforestation phase (e.g. watering). The use of incentives is advisable to increase motivation to participate.
