1.5 Reference to Questionnaire(s) on SLM Approaches

2.1 Short description of the Technology

Definition of the Technology:

Closing the degraded land to let it to regenerate by excluding human and animal interference ans speed up the regeneration process by applying some SWC activities and undertake enrichment plantation.

2.2 Detailed description of the Technology

Description:

Area closure is suitable for degraded lands. Degraded areas are excluded from animal and human contact and integrated with activities that speed up regeneration process such as SWC activities, agronomic measures, vegetative and management measures.

Purpose of the Technology: Area closure improves the productivity of degraded lands and protects down stream fields and properties from flooding and improves ground water recharge.

Establishment / maintenance activities and inputs: Management and utilization plan prepared and agreed. Planning and design of supplimentary measures are integrated.

Natural / human environment: Area closure is applicable in all areas that have lost vegetation cover and has low soil fertility.

2.5 Country/ region/ locations where the Technology has been applied and which are covered by this assessment

2.6 Date of implementation

• 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.):

It is introduced technology.

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation
• conserve ecosystem

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

Comments:

Major land use problems (compiler’s opinion): Overgrazing, low awarness of land users, lack of management plan for communal lands and low level of diversification of land users activities.

Major land use problems (land users’ perception): Shortage of grazing lands, lack of common understanding of the management of common resources.

Semi-nomadism / pastoralism: Yes

Grazingland comments: Inspite of decreasing grazing lands, farmers still want to own some heads of livestock. Grazinglands as a result are highly pressurized. Land users cut grass from area closures and carry them home to feed their livestock. Some land users who have few polts for grazing close them to grow grass.

Plantation forestry: Yes

Problems / comments regarding forest use: Natural forests do not exist. Planted forests are managed by the community. In the SWC area, a larger area was planted some 20 years ago but at present the planted forests have been cleared for cultivation. This is the result of high population growth. Some of the planteed forests have been cleared by demobilizing soldiers.

Type of cropping system and major crops comments: Cereals - Legumes - Cereals

Constraints of infrastructure network (roads, railways, pipe lines, power lines)
