2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Restoration of grazing land invaded by Sida cordifolia through the seeding of Hibiscus sabdariffa, for sustainable access to grazing areas and for reduced conflicts between farmers and livestock keepers.

2.2 Detailed description of the Technology

Description:

The agropastoral zone in the south of the region of Dosso experiences high pressure on land resources. The population is composed mostly of farmers and agro-pastoralists, practicing family-farming and extensive livestock keeping. The grazing areas are communal lands set aside for the animals in the rainy season, enabling the reduction of conflicts between farmers and livestock keepers. For more than two decades these areas have been invaded by Sida cordifolia, a species strongly disliked by the animals. An experiment is being conducted in two rural municipalities of the zone.
Several methods to combat Sida cordifolia have been attempted in the region: weeding, tillage, rotation, etc., but without great success. With the support of the “Program to Support the Livestock Keeping Sector in Niger”, PASEL, financed by the Swiss Cooperation in Niger, the municipalities of Guéchémé and Douméga have tested a method that combines two already known practices (tillage and weeding), and one novel practice, which consists of the seeding of the sites with Hibiscus sabdariffa, or roselle (“Oseille de Guinée”), a plant that is normally used to make tea or eaten as a vegetable. But it is also valuable as a fodder.
In the year following the seeding of Hibiscus sabdariffa, the plants grow with the first rains. Because of its rapid germination, the hibiscus invades the area very quickly, and suffocates the first seedlings of the Sida cordifolia. Using this method, which combines several techniques, the sites have been restored . But they remain vulnerable, because the Sida cordifolia has invaded all the non-cultivated areas in the region, and can very quickly recapture the restored areas. Only more far-reaching and sustained action can put an end to the colonization of the grazing areas. This technology enables the reduction of conflicts between livestock keepers and farmers, while keeping the animals in the region, but at the same time restricting their straying into crop lands. The nutritious character of the fodder that is produced by hibiscus contributes to improved fattening of the animals, and better milk production for the families of neighbouring pastoralists.
From an environmental point of view, the return of certain grasses and herbs has been noted. Eragrotis tremula, Commelina froskalei, and Brachiara ramosa had disappeared. Nevertheless, the livestock keepers fear that the restored zones will be recaptured by Sida cordifolia because the treatment was only carried out on part of the area. However they appreciate the fact that they can keep a part of the herd in place, that land tenure has been secured - and that the municipality has shown interest in the livestock keeping.

4. Technical specifications, implementation activities, inputs, and costs

4.1 Technical drawing of the Technology

{'additional_translations': {}, 'content_type': 'image/jpeg', 'preview_image': '/media/b7/0/b70ddca9-0a71-4fbb-9037-a2f39088c3f8.jpg', 'key': 'Technical drawing', 'value': '/media/b8/d/b8d6ba3a-bc9b-4bfb-a478-1abe8da2cb6f.jpg', 'template': 'raw'}
Technical specifications (related to technical drawing):

Design: randomised Fisher blocks in 4 repetitions.
Unit plots of 5m x 5m
Five (5) treatments (varying in the quantity of roselle - Hibiscus sabdariffa - seed to spread per unit area).
Results:
Observations following the differentiation in seeding Hibiscus sabdariffa on an area with a density of approximately 120 plants of Sida cordifolia per m2:
- T2 to T4: the plants of the two species grow thinly together without impeding each other. The density is not sufficient to cover the entire plot and to prevent the development of Sida cordifolia.
- T5 to T7: not very satisfactory results, but with a clear difference between the plants of Hibiscus sabdariffa and those of Sida cordifolia. Between 10 and 20% of the plots are not sufficiently covered, which explains the presence of several remaining plants of Sida cordifolia.
- T8: full cover (200 plants of Hibiscus sabdariffa per m2 on average). Several plants of Sida cordifolia are still able to grow, but cannot develop and will produce only a small amount of seeds, or none at all in the majority of cases.
These results vary with the soil type: if the soil is fertile, even from treatment T7 onwards the results are very satisfactory, because the leaves grow quickly and provide shade, which is a prerequisite for preventing the development of Sida cordifolia.

4.3 Establishment activities

Activity Timing (season)
1. Site selection April to May
2. Social agreement April to May
3. Securing land tenure preliminary to any action
4. Establishment of management committee May
5. Preparation of the terrain May
6. Purchase of seeds April
7. Sowing at the first or second rains in June
8. Technical monitoring and closure of the areas for grazing June to October
9. Maintenance of the plots June to August
10. Assessment of the biomass October
11. Releasing the area to livestock keepers October
Comments:

The approach implemented in two sites of 50 ha each consists of:
1. Site selection: geo-referencing and verification of the ownership status of the land;
2. Negotiation and establishment of a social agreement between the main users. This process consists of awareness-raising of the local farmers and livestock keepers, agreement on the rules for management and the terms of access, signing of the agreement by the village head and the leader of the livestock keepers (rougga);
3. Securing the land tenure by issuing a land act by the land commission, and registration in the rural records of the municipality;
4. Establishment of the management committee and training of its members in management, organisation and conducting the restoration works in the areas;
5. Preparation of the terrain: improved clearance (to eliminate seeds), tillage by mechanised harrowing using a tractor or ox plow after the first seedlings of Sida cordifolia emerge (first or second rains);
6. Purchase of seeds of Hibiscus sabdariffa on the local markets;
7. Dry sowing or sowing after a rainfall event: in pockets or by broadcasting. The experiments showed that the sowing by broadcasting with a density of 25 to 40 g per m2 was more effective (cf. the technical drawing, plots T7 and T8);
8. Periodic monitoring and partial closure of the areas for grazing: regular field visits by the technical service and by the municipality, surveillance carried out by the communities and paid by the municipality;
9. Maintenance of the plots: weeding by pulling out the emerging plants of Sida cordifolia, prohibition to collect seed;
10. Assessment of the biomass: estimation of the gross production by the communal service for livestock keeping in Doumega (15.5 tonnes of dry matter per ha);
11. After maturity, release of the area to livestock keepers.

The calendar of these practices may vary according to the arrival of the rainy season.

Strong engagement of the communities in the implementation
The securing of grazing areas threatened by degradation, and by the loss of their status as communal lands.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Violation of the rules for the protection of grazing areas by some livestock keepers, who found the period too long. Strengthen the information system, and provide more interactions between the management committee and the livestock keepers.
A mechanism for the rotation of the restoration works in the area has not been established; only a part of 50 ha has been managed. Plan for the remaining area, which was not restored, for the next years of PASEL7.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
The experiment was carried out on a small area compared to the extent of the problem, which covers the entire southern strip of the country. Continue research with the Institute of Agronomic Research in Niger, in order to capitalize on, and develop, a large-scale project to combat this scourge effectively.
