2.1 技术简介

技术定义:

Contour trench cum bund is a bund laid out on contour along with trench either staggered or continuous to check the velocity of run off, conserve in situ moisture, increse ground water recharge and there by establish a sustainable land use system.

2.2 技术的详细说明

说明:

It is a structural measure. The bund is constructed taking the excavated earth from a trench of 1.5m X 0.3m cross section and leaving a berm of 0.3m and put along the contour. Loose boulder water way are constructed on the bund for safe disposal of excess run off.
Purpose: To break the slope of land. To reduce the velocity of runoff. To increase the in situ soil moisture and increase ground water table. To reduce down stream sand casting.

Establishment / maintenance activities and inputs: The process adopted for implementation of the intervention followed participatory planning through resource mapping, transect, well being ranking, problem identification, prioritisation and negotiation; thus benefit sharing, contribution and future maintenance of the stucture is ensured before establishment of the structure. The poor land and poor people get the opportunity first.

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 fertile top soil is gradually washed away.Productivity of the soil is also reduced. Thus, farmer is only taking minor millet in kharif.

Major land use problems (land users’ perception): Loss of production. Soil is unable to retain moisture, so we suffer crop loss during long dry spell.Due to sand casting crop is also partially damaged in the down stream.

Nomadism: People allow the cattle to graze freely in the field after the crop is harvested

Selective felling of (semi-) natural forests: Yes

Problems / comments regarding forest use: People have started managing forest through VSS and Forest protection committee.

Type of cropping system and major crops comments: minor millets and up land paddy are the major crop under rain fed condition

注释:

Main type of degradation addressed: Wt: loss of topsoil / surface erosion

Secondary types of degradation addressed: Wg: gully erosion / gullying

Main causes of degradation: deforestation / removal of natural vegetation (incl. forest fires), education, access to knowledge and support services (Absence of institutional arrangements to disseminate the knowledge from lab to land and involve the users in implementation)

Secondary causes of degradation: overgrazing (Subsistence economy, dependance on forests for fuelwood and fodder, livestock were low quality, free grazing type. And these were no regulatory mechanisms to share usufruct from forests with people.), poverty / wealth (Lack of capital at the grassroot to take the initiative by the farmers themselves)
