2.1 技术简介

技术定义:

Area enclosures for protection of riverine ecosystem and purposeful regeneration of mulching and pasture materials for cut and carry

2.2 技术的详细说明

说明:

Area enclosure is done in low grazing range lands of average slope 2 – 5%. Enclosure is done by demarcating the fragile land that has direct impact to the riverine ecosystem. The land is exposed to degradation through overgrazing and soil compaction by livestock, bush fire, river bank erosion and reduced quality of pasture spps. Demarcation is done by planting trees in identified area situated about 300 meters from the riverine buffer zone. The preferred plants are Ficus thonigii. The average space between trees is 2 meters. Physical enclosure is supported and enhanced by use of protective bylaws. Reseeding of nutritious pasture species is also done and the area is left under protection for growth and regeneration of mulch, pastures and other vegetation to take place. The common pasture species reseeded are Leucaena spp, cannavaria brazile, clitoria tenatea, sesbania sesban, stylothensis, cajanus cajan, chloris gayana, branchalia spps . Direct grazing is prohibited and mulch and pasture materials are accessed through controlled and organized cut and carry.
Area enclosure is meant for rehabilitation of the riverine ecosystem and prevention of further degradation. Mulch and high nutritious pasture materials that are accessed through organized cut and carry procedures improve crop and animal productivity and have both direct and indirect impact to diversification of income sources and thus play significant role in putting the triple win solution into reality.

Purpose of the Technology: Purpose: 1) To improve vegetative cover, reduce soil erosion and prevent and rehabilitate degradation of the riverine ecosystem 2) Ensure sustainable availability and accessibility of mulch and nutritious pasture that are need for increased crop and livestock productivity 3) Promote use of environmental friendly exploitation of land resources (i.e. mulch, pasture, grass carpeting and other materials) and 4) Promote direct and indirect diversification of income sources.

Establishment / maintenance activities and inputs: Establishment and recurrent activities includes: area identification and measurement; slashing and land preparation for boundary tree planting and pasture reseeding; collection of planting materials and planting along defined boundaries for demarcation; procurement of seed and reseeding of nutritious and palatable pasture species; selective weeding; area reshaping and gap filling.

Natural / human environment: Bio-physically the area is semi natural grassland with grasses and shrubs trees. The technology is a combination of management and vegetative measure (area enclosure, demarcation using ficus thonigii and reseeding of nutritious pasture). Climatic zone is sub humid with 210 length of growing period (LGP). Slope category is gentle lying between 2-5%. Soil texture is fine heavy (clay) with medium soil depth.
Social economic wise the area is dominated by handy tools typology of mechanization. Production system is mixed (both for subsistence and commercial purposes). Inputs used includes tools (hand hoe, machete, sickles, spade and mattock), light and heavy labour, pasture seeds and tree planting materials with average annual costs of 1084.3 USD per hectare. Land ownership in technological area is communal.

是

具体说明混合土地使用（作物/放牧/树木）:

• 林牧业

注释:

Livestock density (if relevant):

50-100 LU /km2

Major land use problems (compiler’s opinion): Soil erosion due to downstream run off exacerbated by loss of vegetation cover due to bush fire and soil compaction caused by overgrazing, degradation of the riverine ecosystem caused by River bank erosion, land bareness and exposure to direct sunlight and excessive unproductive loss of both green and blue water.

Major land use problems (land users’ perception): River pollution, erosion of the river bank, land bareness and reduction of mulching and pasture materials.

Nomadism: People with large herd of animal move with their animals in search of adequate pasture
Semi-nomadism / pastoralism: Exercised with people with few stock.
Cut-and-carry/ zero grazing: done by farmers who usuall keep dairy goats and cattles.
Grazingland comments: Area enclosure is largely meant to control land degradation of the riverine ecosystem through overgrazing by people who own large number of stocks at the same time promote organized, sustainable and environmental friendly exploitation of the fragile land lands (e.g. controlled cut and carry rather than direct grazing in the riverine ecosystem).
