2. SLM技术的说明

2.1 技术简介

技术定义:

Transformation of degraded pastureland to high quality fodder plots.

2.2 技术的详细说明

说明:

Grass and legumes are planted on degraded pasture land in fenced fodder plots within the drought prone cattle corridor of Kiruhura district. This climatic zone is characterized by short periods of intense rains followed by long dry spells. Previously, most of the pastoralists of Kiruhura led a nomadic lifestyle, moving their livestock over large areas in search of pasture and water. The combined effects of prolonged droughts and livestock movement over a defined corridor, led to increasing degradation of pastureland, reducing both the quantity and quality of pastures and worsening soil erosion. Therefore the pastoralists have settled down plant pastures instead. Grasses cultivated in the range lands of Kiruhura are Pennisetum purpureum (elephant grass), Stylosanthes guianensis (stylo), Chloris gayana. The legumes are Calliandra spp. and lablab.

Purpose of the Technology: The main objective of the technology is to improve the availability of quality forage and fodder for livestock during the dry season and to feed small ruminants. The other objective is to stop runoff which usually destroys crops, increase water infiltration during the rains and lessen the effect of floods. The benefits of fodder cropping include the protection of soil from erosion by increasing surface cover, improved soil fertility from the legumes, improved livestock production and consequently higher manure production.

Establishment / maintenance activities and inputs: Establishment involves digging, to loosen the soil and remove other grasses that would compete with the planted grasses. Digging is labor intensive and the land owner usually hires labor. The technology requires simple gardening tools such as the hand hoe for digging the soil, and a panga to clear invasive bushes, usually Lantana camara. In addition, irrigation may be necessary in the first 2 to 3 months even during the rainy season. Elephant grass is propagated vegetatively using cuttings planted in rows. Chloris gayana is propagated by broadcasting the seed. Lablab seeds are germinated by soaking in water and then planted directly in the prepared plot. Calliandra is first planted in nurseries before transplanting the seedlings.

Because of the erratic rains, irrigating the plots in the first few months of cultivation is critical.

Natural / human environment: The plots fenced off to protect the fodder crops.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

Fencing the land is the most important factor in establishing the technology. The whole cattle corridor is an extended range land with a lot of livestock. Fodder plots constantly face destruction by freely roaming livestock and therefore fencing is a requirement. Paddocking also requires fencing to divide the farm into portions of pasture. Both materials and labor are costly.

说明土地使用者的其他有关特征:

Land users applying the Technology are mainly common / average land users
Difference in the involvement of women and men: Herds and the land they graze on traditionally belongs to men. This seems to have remained the case, where women's roles are within the house and around the compound while men tend the live stock. Nonetheless, women are getting hired as labourers in the nurseries and for digging.
Population density: 10-50 persons/km2
Annual population growth: 2% - 3%
15% of the land users are rich and own 30% of the land (can afford to spend 150.00 US$ per month on farm expenses).
60% of the land users are average wealthy and own 40% of the land (can spend 500.00 annually on the farm).
Off-farm income specification: Most of the economy in Kiruhura district is farm-based. Almost everybody earns directly from their farm produce or labour.
Market orientation: Mixed (ranked 1, herders have surplus milk for sale) and subsistence (ranked 2, herders grow their own food)

Establishment costs are rather high. In the medium to longer term, the benefits are immense. Maintenance costs are reduced once the technology is established because expenditure on animal drugs goes down with decreasing parasite infestations (especially ticks) which were a result of mixing with untreated herds before.

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
Improved income from milk with reduced expenses on acaricides and other drugs means that household income is higher

How can they be sustained / enhanced? Encourage improvement of the herd by reducing the numbers and enhancing the quality through breeding and acqusition
Less time is spent on searching for pastures further afield.

How can they be sustained / enhanced? Encourage the herder to put more acreage under planted pastures
编制者或其他关键资源人员认为的长处/优势/机会
There is enough grass and fodder for the herd during the rainy season and hay during the extended droughts.

How can they be sustained / enhanced? More mobilization campaigns, grass and legume seeds and other incentives should be availed to the herders to enhance rate and extent of adoption.
Intensive grazing favours smaller, high productivity herds

How can they be sustained / enhanced? Policy to improve herd quality should be pursued at government level
Planted pasture enhances responsibility to protect and maintain grazing land by the owner, thereby improving capacity to sustain soil management benefits (increased surface cover, reduced water erosion)

How can they be sustained / enhanced? Community level by-laws should be enacted to compel every herder to have some planted pastures for fodder.
Improved milk and other farm product yields

How can they be sustained / enhanced? Introduce marketing strategies including cooperatives to ensure that the benefits go to the farmers and not marketing middle-men.

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?
There is shortage of labor to increase acreage, cut the grass and legumes from the pasture plots and prepare fodder for semi zero-grazing Use simple machines where possible
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?
Establishment costs are rather high Benefits demonstrated by the herders who adopted the technology should convince government and commercial banks that the technology is profitable. Upon this evidence alone, these institutions should avail the herders the necessary capital.
Technology is labour intensive Productivity is even higher, therefore innovations that introduce mechanization should be encouraged (it is the normal progression of agricultural/industrial development)
