1.5 参考关于SLM方法（使用WOCAT记录的SLM方法）的调查问卷

2.1 技术简介

技术定义:

A soil and water conservation channel is an excavated trench along the contour with tie bands after an interval to trap water and soil which are being washed down the slopes by a downpour

2.2 技术的详细说明

说明:

The technology is applied in already existing degraded farmlands, which are individually owned. An average farm size is less than half an acre.

A typical soil and water conservation channel is a trench 1m wide, 1m deep and with tie bands (1m wide to avoid flow of water along the trench) at intervals of 10m along the contour. The excavated soil is used piled up into an earth bund next to the trench at lower side and stabilized by planting hedge rows of "Starria grass" to avoid erosion.

This technology reduces the speed of water running down the slope during a downpour and traps the water and soil that is being washed thereby reducing soil erosion and increasing water retention.

Areas which are prone to degradation by erosion are identified and later, the farmers are trained on benefits of this technology, how to set out the technology by use of the ‘A – frame’, how to construct the channels and how to maintain them by periodic de-silting and planting grasses and shrubs on the bands.

The 'A - Frame' is an A shaped structure made from wooden poles or thin metal poles that can be easily constructed and used to peg flat or graded contours or water drains.

This technology helps maintain the good top soil, which would have otherwise been washed down the slope into the valley and increases water retention.

The land users like this technology because their soil is not lost but what they dislike about this technology is that it is labour intensive, setting it out is technical and not easily conceptualized and it takes part of the land. Individual land users excavate these channels in their individual plots of land using simple hand tools like hoes, spades and pick axes.

注释:

The land users, after being trained, set out the soil and water conservation channels for themselves but the tools are beyond the financial capacity of the land user hence the need for subsidy

4.5 维护/经常性活动

劳动力	Desilting of channels (when half full)	meter	1.0	0.265	0.27	100.0
劳动力	Trimming of hedge rows (100m per day)	days	1.0	0.0212	0.02	100.0
技术维护所需总成本					0.29

注释:

The initial investment of the equipment is adequate for maintenance at least for some years

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

The costs have been calculated basing on depth of top soil of 51 – 80cm. When the depth of the top soil is shallow, then the costs of breaking the underlying sub-surface layers, which are usually rock, are much higher. Also during the rainy season, the soil is more workable

The costs of maintenance will be less where the rest of the landscape also has conservation channels, has good vegetative cover and where the hill slope is gentle.

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
1) It controls soil loss from the land users garden
2) It provides silt which is spread in their garden
3) Hedge rows are used as fodder and as mulching material
4) The conserved water is used to benefit the plants in the same garden

编制者或其他关键资源人员认为的长处/优势/机会
1) It improves water percolation in the soil which increases soil moisture content and increases ground water recharge
2) It is a simple technology which uses simple hand tools
3) It reduces conflicts related to land being washed into the neighbours plot since land is fragmented

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？
1) This technology requires a lot of hard labour	The land users were encouraged to form small groups which work together to ease the work and share knowledge and skill
2) Land users feel that the channels take up alot of their land, which would otherwise be used for growing crops	The land users have been helped to appreciate the benefits of the technology in making the seemingly smaller land more productive

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？
1) This technology is dependent on land users continued efforts in de-silting and maintenance of the hedge rows. When this is not done the technology fails	Land users are encouraged to periodically desilt the channels
2) The effectiveness of this technology is dependent on the compliance of other land users in the landscape. For example if it is done downhill and not uphill, then the channels will be overwhelmed by the volume of the soil and water runoff	All community members were sensitised on the importance and effectiveness of this technology and existing by-laws will foster members uphill to practice the technology. The benefits of the technology will encourage other land users to adopt it
3) The process of maintaining and rolling out this technology requires engagement of many stakeholders	Management structures, which are well linked with government structures, have been set up and trained at various levels to manage the process of maintaining and rolling out the technology
