2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The technology was developed and used to select key pasture and fodder species and reintroduce them into strategic areas through stakeholder participation. The technology was also supported by communal management plans were created to address root causes of land degradation.

2.2 Detailed description of the Technology

Description:

The technology was developed and implemented through the RETESA Project “Land rehabilitation and rangelands management in smallholders agro-pastoral production systems in south western Angola”, which is a project owned and implemented by the Ministry of Environment of the Government of Angola with technical and methodological assistance from The Food and Agriculture Organization of the United Nations (FAO) and financed by the Global Environmental Found (GEF).

Improper grazing regimes and animal management on part of pastoral communities in SW Angola have led to degradation of rangeland and pastoral resources, with perennial grassland species and shrubs having been effectively eliminated from lowland grazing areas. The pastoral communities of the area know their environment extremely well and are aware of the land degradation happening around them. They identified crucial areas for the rehabilitation works, selecting mostly areas around water points that were used both by local and transhumant herders. Through these works, the locals sought to increase ground cover to reduce sediment loads entering waterways (erosion control), provide shade for livestock, increase forage production and introduce legumes and multiuse forage trees in areas of high animal traffic. A total of 4 areas in the Bibala and Virei Municipalities were identified for the activities.

The communities were heavily involved in the selection and propagation of plant species for the rehabilitation works. The project field staff also ran participatory, field palatability trials with them to confirm the plants selected met their expectations and to enhance their understanding of livestock nutrition and how it related to animal health. Once the species were chosen, seed was collected by the communities and the Project Technicians and was multiplied in 32 Agro-Pastoral Field School Nurseries and 2 Government funded Veterinary Research Stations. A total of 15 species were identified, with Eragrostis superba, Urochloa mosambicensis, Acacia nilotica, Faidherbia albida, Leucaena leucocephala and Moringa oleifera being the most valued by the communities as forage and multiuse species. Trees and shrubs were germinated from seed with success. As their seeds failed to germinate by standard methods, native grass species were multiplied by root divisions of plants collected in cultivated fields so as not to remove any from natural areas. Early field trials ruled out direct seeding methods.

As the majority of areas selected for the rehabilitation works were focused around water points and waterways, the soils were generally alluvial, sandy loams. Precipitation is highest in the areas to the north, ranging from 600mm in the upper areas of the Bibala Municipality to 200mm in the areas to the south in Virei. In general, the vegetation communities could be described as dry sclerophyll woodlands with Colophospermum mopane being the dominant tree species, with forest cover decreasing in height and density as one moves south toward drier areas.

Through close collaboration with the participant communities, 3 rehabilitation methods were designed and improved upon throughout the Project's duration. Method 1 was used to plant open areas within the rehabilitation zone, Method 2 was used to introduce and protect concentrated plantings of the selected species in strategic locations within the landscape and Method 3 was used to recuperate riparian vegetation and reduce sediment loads in waterways. The 3 Methods used are described in more detail in the Technical Drawing on page 3. To increase appropriation and increase the effectiveness of the rehabilitation works, land management plans and other supporting activities were also carried out.

  • V2: Grasses and perennial herbaceous plants
management measures

management measures

  • M2: Change of management/ intensity level
Comments:

The management plans created at the community and administrative level identify a number of large areas which are to serve as 'Grazing Reverses' for the dry season. Therefore, the agreements call for all livestock to abandon the area at the onset of the first rains and not return until the Pastoral Management Forum agrees to open the area for grazing. Once open, the range is available to all pastoralists, those that live in the immediate area and those moving through on their transhumance migration.

4.1 Technical drawing of the Technology

Author:

Projecto RETESA

Date:

10/01/2018

4.2 Technical specifications/ explanations of technical drawing

Plantings are typically based on 3 established methods, as seen in the exemples provided.
- Method 1 relies on placing a leguminous, multiuse tree species in the ground with two native grass species to each side of the tree. The holes are dug and a small amount of manure is placed in the bottom of the hole, adding some water to the hole if it is readily available. Then the trees and grasses are planted and well watered. Finally, a branch or two of thorny shrubs or trees are placed over the plants to protect them from grazing (where possible, attempts are made to use thorny branches that were already dead or had fallen).
- Method 2 requires the creation of an enclosed, protected area which is then planted in high densities, preferably in low-lying areas where soil moisture is available to support such high concentrations of plants. Dry, dead branches from thorny trees and shrubs were used to create the enclosures and provide protection to these plantings.
- Method 3 is based on the creation of a 'Leaky weir', which is a small stone barrier planted with a mixture of native riparian species placed horizontally to the flow of water. It is intended to slow the flow of water and allow for the recovery of riparian vegetation. The plants are also protected with dry, dead branches from thorny trees and shrubs in this method.
To increase their effectiveness, it is recommended that the 3 methods be combined within the landscape, as seen in the 4th slide 'Field application of methods'.

4.3 General information regarding the calculation of inputs and costs

Specify how costs and inputs were calculated:
  • per Technology unit
Specify unit:

3345 seedlings produced, delivered and planted

Specify volume, length, etc. (if relevant):

3345 units

Specify currency used for cost calculations:
  • US Dollars
Indicate average wage cost of hired labour per day:

6 Dollars

4.4 Establishment activities

Activity Type of measure Timing
1. Meetings and field visits with participant communities to identify plant species and their uses Other measures Best during growing season
2. Further meetings to decide on which species are to be multiplied and arrange seed collection Other measures Near end of growing season
3. Seed collection and transportation Other measures When seed is available (varies with species)
4. Instalation of irrigation systems Structural Most communiites need a water extraction and distribution system to create nurseries
5. Delivery of nursery supplies and instalation of shade cloth Structural Nurseries should have water access and shade
6. Planting of seeds and care for seedlings at nursery Vegetative Formed part of Agro-Pastoral Farmer Field School activities
7. Identification of planting areas and timing Other measures Should be at beginning of rainy season, or when soil moisture permits
8. Organisation of materials and tools Other measures At least 1 week before the planting
9. Planting day (preparation of planting holes and transplanting of seedlings) Vegetative 2 days maximum was seen to be optimal
10. Watering until the plants are established Agronomic Usually a maximum of 3 watering over 1 week after the plantings
11. Follow up visits to make sure management agreements are being respected and plants are not being eaten by stock until they are ready Management Plants should not be grazed for at least 6 months from planting time until they are well established
Comments:

The activities and costs given were those needed to produce and plant 3,345 trees and grasses in the 4 rehabilitation areas. Given that 3.345 plants were produced at a cost of $3284.75, the cost per plant produced and planted in the field is $0.98. As the inputs and materials for the 3 methods came from the same source and the methods were implemented together at the same time, no distinction of the costs for each method is avaliable, though the labour and materials are similar enough so that they one could assign the same costs for the 3.
As per the question of planting densities, they are often dependent on numerous factores but one can easily calculate the costs per hectare by knowing plant densities and deducing the costs.

Total costs for establishment of the Technology 3284.75
If land user bore less than 100% of costs, indicate who covered the remaining costs:

Remaining costs were provided by the RETESA Project.

Comments:

Production depends on the ability of the pastoral communities to produce viable plants. If they are unable to do so, then plants can be bought from Government funded nurseries, though costs per plant will most rise though it can substitute the need for having to purchase a water supply system. The total shown here reflects a percentage (16%) of the costs of installing a water system that supplied water to the whole of the Agro-Pastoral Farmer Field School. These systems usually included a 10,000 litre water tank, a gasoline water pump, extraction pipe and parts, 100 to 200 mts of 1.5" hoses and parts and 3 kms of drip irrigation hose.

4.6 Maintenance/ recurrent activities

Activity Type of measure Timing/ frequency
1. Meetings to ensure management agreements are being respected. Management Once every 3 to 6 months, especially before and after rainy season.
2. Repairs and replacement of nursery supplies. Structural Once a year.
3. Replanting of dead seedlings Vegetative Just before and during rainy season.

4.7 Costs and inputs needed for maintenance/ recurrent activities (per year)

Total costs for maintenance of the Technology 256.0
If land user bore less than 100% of costs, indicate who covered the remaining costs:

The RETESA Project provided an important part of both material and technical support to the communities, though the communities also contributed substantially.

4.8 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

The activities and costs given were those needed to produce and plant 3,345 trees and grasses in the 4 rehabilitation areas. Given that 3.345 plants were produced at a cost of $3284.75, the cost per plant produced and planted in the field is $0.98. Seedlings avaliable through local, government nurseries were $2.00 per unit, but only exotic ornamentals were avaliable. However, it can be expected that in other contexts and locations, it would be cheaper to buy seedlings instead of training communities and creating numerous small scale nurseries, though clearly these communities will not appropriate the process as well as if they were involved from the beginning.

fodder quality

decreased
increased
Quantity before SLM:

No crop residues or fodder plantings used

Quantity after SLM:

Crop residues and fodder plantings incorporated in cropping areas

Comments/ specify:

The process allowed Project Technicians to educate communities on the use of crop residues as fodder and the planting of multiuse trees within cropping areas to provide green fodder in the dry season. The reintroduction of drought tolerante, quality native grasses should also lead an increase in fodder production over the coming year.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Communities learn about plants' role in the wider ecosystem, how to select and multiply key fruit, fodder or timber species and should see an increase in their horticultural and livestock production, leading to improved nutrition or income.
Done properly, it can be a cost-effective and reliable way to produce the plants needed within family units.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
When the plants are produced in collaboration with the local pastoral communities, the benefits are wide ranging, promoting everything from environmental awareness to technical and practical knowledge.
It remains a cost effective way of improving key productive species and increasing community resilence.
Increasing biomass and introducing better management cycles contribute to reducing land degradation and improve nutrient and energy cycling.

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?
Can require stable supply of water, and labour costs can increase if water sources are not easily accessible. Locate nurseries near reliable and accessible water sources.
Can require permanent residence, so as to be able to care for plants until they are developed and placed in the ground at the proper date in the calendar (before or during rainy season). Not easy in nomadic cultures.
Early attempts often fail to produce lasting results. Concentrate early efforts on small experimental plots so as to fine-tune planting methods and timing.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
The technology is usually not suitable for large areas of land (>1,000 hectares). Compliment any rehabilitation efforts with improved management plans which are developed with stakeholder input and approval.
Plant losses are typically high, especially if rains fail to arrive, or if the year is abnormally dry. Watch weather forecast to try and focus planting campaigns on those days with a high probability of rain.
Local species are often not valued by local officials and technicians, leading to a predominance of exotic species in rehabilitation works. Undertake awareness and training sessions which highlight the value and uses of native species with local land users and administrative officials.
