2.1 Short description of the Technology

Definition of the Technology:

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 Detailed description of the Technology

Description:

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.

0.32

If precise area is not known, indicate approximate area covered:

• 0.1-1 km2

Comments:

Total area covered by the SLM Technology is 0.32 km2.

The technology area comprises of 0.3 2km2 within the watershed of 6 km2. The technology is an improvement of the age old practice of field bunding by the farmers.This has been promoted by the Soil Conservation department and watershed mission through watershed development programme.

• more than 50 years ago (traditional)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

Indegeneous but improved by Soil Conservation department, Watershed Mission, UNDP.

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation

3.2 Current land use type(s) where the Technology is applied

Land use mixed within the same land unit:

Yes

Specify mixed land use (crops/ grazing/ trees):

• Agro-silvopastoralism

Cropland

• Annual cropping

Annual cropping - Specify crops:

• cereals - millet

• rice

Number of growing seasons per year:

• 1

Specify:

Longest growing period in days: 150 Longest growing period from month to month: Jun - Oct

Grazing land

Extensive grazing:

• Nomadism

• cattle

Forest/ woodlands

• (Semi-)natural forests/ woodlands

(Semi-)natural forests/ woodlands: Specify management type:

• Selective felling

Products and services:

• Fuelwood
• Fruits and nuts
• Grazing/ browsing

Comments:

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

3.4 Water supply

Water supply for the land on which the Technology is applied:

• rainfed

3.5 SLM group to which the Technology belongs

• cross-slope measure
• water diversion and drainage
• surface water management (spring, river, lakes, sea)

3.6 SLM measures comprising the Technology

3.7 Main types of land degradation addressed by the Technology

soil erosion by water

• Wt: loss of topsoil/ surface erosion
• Wg: gully erosion/ gullying

Comments:

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)

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:

• reduce land degradation
