2. SLM技术的说明

2.1 技术简介

技术定义:

This technology is designed for the high altitude mountains areas, where biomass and growing trees are limited, first because of the harsh climatic conditions and secondly because of the limited arable lands for growing biomass and forests. Thermo insulation is applied in order to keep warmth inside and save using wood and biomass.

2.2 技术的详细说明

说明:

The technology is applied in the mountainous rural areas of Tajikistan, in Rasht, Khatlon and GBAO. In this mountain regions wood and biomass are usually limited because of the harsh climate, risky agricultural zone and limited arable land. In the first decade of the transition period after the collapse of the Soviet Union problems with electricity and therfore the demand for fuel and wood increased. This caused a lot of forest degradation, because people were cutting trees from government owned and community areas for their fuel needs and used animal manure for heating their houses and cooking food. The technology is specifically designed to use low cost materials so that rural households can afford it. The technology consists of material like foil and wood to build frames for some layers to keep in the heat. Depending on the altitude, which is linked to the climate condition, the number of layers is increased where the climate is cold. The layer in between contains air, which prevents outside and inside air to move out/in. The technology was intended for saving up to 30% fuel. The technology includes support of entrepreneurs to make foil available in the market and provides training for local masters and labourers in designing and constructing of the technology. The main benefit is to contribute to biomass savings and forest preservation through reduced use of wood for heating and cooking. Land users are in favour because through this technology they are using less wood and save forest. They also burn less manure and can use it as fertilizers for their land. The technology brings comfort for longer periods of time by keeping heat inside the room. In addition it contribute also to hygine and sanitation, as less fire making prevents smoke emission and therefore keeps the rooms clean. On first sight the technology seems expensive, becasue of the material costs but in the long run when the cost effectiveness is explained land users accepted it.

技术规范(与技术图纸相关):

A wooden frames is installed on the wall to cover the whole area. Foil will be stretched and will be fixed on the wooden frame on the wall. Based on the need number of layers is selected, which depend on the min/max outside temperature. If required according to the climate and wether of the area and based on altitude another frame from wood will be constructed on the foil and then again another layer of foil will be fixed. The scheme show the frame on the wall with thermo-insulation materials attached to it. The distance between two part of the foil should be an average 2-3sm.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险 如何克服它们?
In the short term a big investment is required. Funding mechanisms should be improved to provide access for farmers/rural population to invest in such technology. Some of the incentive mechanisms should be worked out for replicating the mechanism.
Specialized master skills are required to implement the technology. More capacity building for existing local farmers should be organized at the local level for long term sustainability.
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?
By implementing one or two demonstrations at the household level the effect for the purpose of replication and dissemination is very low. Demonstrations should be applied in public places like school or hospitals so everybody can have access and see the impact.
