2.1 技术简介

技术定义:

Hillside forward-sloping terracing and stabilisation using structural and vegetative measures

2.2 技术的详细说明

说明:

This technology addresses the soil erosion and water runoff problems associated with traditional outward-sloping terraces by reshaping the land into a series of level or gently sloping platforms across the slope. This technology is a variant of sloping land agricultural technology (SALT) or contour hedgerow technology. Nitrogen-fixing hedgerow species and quality fodder grass species, which bind the soil, are cultivated along terrace riser margins to improve terrace stability. This also enhances soil fertility and increases fodder availability. The plants are grown in either single or multiple layers. The practice is applied under rainfed conditions and is culturally acceptable and affordable. After establishment, the technology also addresses the problems of fodder scarcity making it easier and less time consuming for women and
girls to gather fodder.
The hedgerow and grass species are established between January and June. Complete establishment of this technology may take one year. The first step in creating the terraces is to build retaining walls using cement bags filled with soil which are then supported with bamboo cuttings along the contour (= future terrace risers). This divides the land into the planned terrace sections. The length and width of the terraces depends on the size and shape of the original field. Secondly, the soil is excavated from the upper part of the terraces and is used to build up the lower part above and behind the terrace riser wall to create a level bed. The fertile top soil must be kept aside and later spread over the newly terraced fields. The final step is to plant grass and hedgerow species on the outermost margins of the terrace above the risers.
Maintenance involves slicing the terrace risers once or twice a year with a spade, and smoothing off rills that appear on the surface of terraces after the premonsoon and monsoon periods. Hedgerows should be cut regularly but not more than twice a year, normally to a height of about 50 cm. Grasses should be cut about once to twice a month depending on their rate of growth.
The technology is applied under humid subtropical climate conditions (1300 mm annual rainfall with about 80% of it falling in the monsoon months of June - September). The case study area has hill slopes of 16-30% that are mostly highly erodible red soils (FAO classification: luvisols).

3.1 该技术的主要目的

• 减少、预防、恢复土地退化

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): The major land use problem in the area documented is the small per capita cropping landholding size. The fields are mostly rainfed and have low soil fertility and acidity problems and are susceptible to erosion. The high intensity of rainfall leads to considerable soil loss (rill and gully erosion) at the beginning of rainy seasons.

Major land use problems (land users’ perception): The production of the cultivable land is declining. Management of slopes is inappropriate, the farmers experience serious constraints in terms of adopting better farming options, e.g., cash crops (due to fertility / erosion and soil moisture problems).

Type of cropping system and major crops comments: Rice Premonsoon and monsoon( March- Novevember ) or Maize intercropped with Beans (April to August) ,Wheat and Potato ( September to January/ February) ,Tomato (January/February- April )

注释:

Machinery/ tools: Spade, Shovel, spade

All costs and amounts... are very roughly estimated by the technicians and authors.
Costs for structural measures are calculated considering the volume of excavated earth. 1 cubic meter excavated earth = 0.69 USD (labour cost). For vegetative measures it is normally based on daily wage = 1.4 USD as in 2006.
Labour cost is the major expenditure in the initial stage.
costs for tools for establishment are representative for the situation when tools for implementation of the SWC technology are not available (normally they are since the technology does not require very specific tools).

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
The price of land increased considerably from NRs 30,000 in 2001 (for 1 ropani – 508.5 sq. m) to between NRs 100, 000 and NRs 150,000 per ropani after the technology was established How can they be sustained / enhanced? The price would increase further if irrigation facilities were installed
Pedicels of Tephosia and Sunhemp can be used for firewood.
Instead of planting only maize a farmer started planting rice (primary crop) and cash crops like potato / tomato (secondary crops).

编制者或其他关键资源人员认为的长处/优势/机会
The area of levelled terraces nearly doubled in Kubinde village from 2001 to 2003, which is an indicator of increased awareness of the benefi ts of soil and water conservation. How can they be sustained / enhanced? Experience sharing would help expand the area under improved terraces.
Land productivity increased, maize, potato and bean production increased, vegetables and rice production started. How can they be sustained / enhanced? Irrigation facility could increase the production capacity of the terraces.
Availability of grass/fodder (nitrogen fixing) increased. How can they be sustained / enhanced? Planting horticultural fruits could increase farm incomes and so it should be promoted and more nitrogen fi xing species (preferably local) should be tried out

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 fi rst year of implementation, maize production was reduced due to soil amendment	a phenomenon which is likely to occur with new terrace formation

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？
Presently the vegetative technology is confined to terrace margins	it should be extended to the risers also.
