2.1 Courte description de la Technologie

Définition de la Technologie:

Rehabilitation of communal grazing lands, through planting of improved grass and fodder trees and land subdivision, to improve fodder and consequently livestock production.

2.2 Description détaillée de la Technologie

Description:

This case study focuses on the highly populated, humid highland regions of Ethiopia that experience serious shortages of pasture. Due to rapid population growth, communal grazing areas are increasingly being converted into cropland. This has led to enormous pressure on the little remaining grazing land, through overstocking of dairy cows and oxen, and thus overgrazing, resulting in considerably decreased productivity.
Improved grazing land management is vital to increase food security and alleviate poverty, as well as to bring environmental rewards. To address these problems, the national SWC programme in Ethiopia initiated a grazing land management project over a decade ago. Implementation of the technology includes the initial delineating of the grazing land, and then fencing to exclude open access. This is followed by land preparation, application of compost (and, if necessary, inorganic fertilizers) to improve soil fertility, then planting of improved local and exotic fodder species, including multipurpose shrubs/trees such as Leucaena sp. and Sesbania sp. and the local desho grass (Pennisetum sp.). Desho has a high nutritive value and regular cuts are ensured. It is planted by splits, which have high survival rates and establish better than grasses which are seeded. Other grass seeds, as well as legumes, including alfalfa (lucerne: Medicago sativa) and clovers in some cases, are mixed with fodder tree seeds and then broadcast.
Maintenance activities such as weeding, manuring and replanting ensure proper establishment and persistence. Fodder is cut and carried to stall-fed livestock. Once a year, grass is cut for hay, which is stored to feed animals during the dry season. Experience shows that such grazing land is best managed when individually owned and used. In the study area, the community has distributed small plots (<0.5 ha) of communal grazing land to individual users to develop, manage and use.
The overall purpose of the intervention is to improve the productivity of grazing land and control land degradation through the introduction of productive techniques and improved fodder species, which consequently improve livestock production. Commercialisation of animals and marketing of their products increases the income of farmers. The government provides technical assistance, close follow-up, and some inputs for initial establishment. Land users are trained in compost/ manure application, planting of seeds, splits and seedlings, and general maintenance.

Commentaires:

Major land use problems (compiler’s opinion): Population growth has resulted in a substantial reduction in land holdings (<0.5 ha per family) and this in turn has led inevitably to encroachment onto communal grazing lands for cultivation. Livestock numbers on the other hand have remained unchanged, and this has led to overstocking of the few areas left. Livestock production, which accounts for 40% of the average household income, is thus reduced and farmers’ income declines correspondingly.

Commentaires:

Seedlings are given by the government for initial establishment. For further extension of area and replanting, the
land users set up their own nurseries. After 2-3 years maintenance costs decrease substantially as the grass cover closes up and maintenance activities such as replanting/enrichment planting and compost application are reduced or cease. The local daily wage is about US$ 0.70 a day, but varies depending on the intensity of the work. In this calculation the standard rate has been applied.
Farmers usually cannot afford fertilizers. Milk production compensates for some of the high investment costs (previously, production was low).

Availability of fodder (grass, hay, shrubs) in sufficient quantities, and all year round How can they be sustained / enhanced? Increase the area under such development.
Reduction in soil loss and land degradation How can they be sustained / enhanced? Maintain adequate cover by planting more grass.
Introduction of high yielding species as well as increase in land productivity and livestock production How can they be sustained / enhanced? ntroduce bigger variability of quality species and improve maintenance activities such as weeding and cultivation.
Improved diet: livestock by-products such as milk, butter and cheese are essential food items required by the households How can they be sustained / enhanced? Keep on increasing/improving quantity/quality of livestock feed.
Increased income through commercialisation and marketing of animals and their by-products. Meets financial needs for paying taxes, school fees, clothes etc.
Rehabilitation of communal grazing lands is both a technical and social challenge. Here is a promising example from Ethiopia that is spreading quickly. The key is subdivision of land into individual plots where cut-and-carry of grass and stall-feeding of livestock is practiced. This is only a possible option, however, where rainfall is favourable. land use rights: individual for cropland, open access (unorganised/communally used) for grazing land, except for the case study area where the rights to rehabilitated grazing land are given to individuals

6.8 Faiblesses/ inconvénients/ risques de la Technologie et moyens de les surmonter

Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé	Comment peuvent-ils être surmontés?
At the initial stage of establishment it is very labour intensive	Use of improved land preparation methods such as oxen ploughing.
Substantial cash for inputs, particularly seedlings, is required	Produce seedlings of improved species and making compost in backyards.
Needs high fertilizer application	Focus more on organic fertilizers.
High pressure on remaining grazing areas	Keep animals in stall (stable) or park, at least part of the day and during the night, and introduce cut-and-carry more widely.
