2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Propagation of “samata” cuttings for long-term provision of supplementary livestock fodder to reduce the pressure on natural vegetation.

2.2 Descripción detallada de la Tecnología

Descripción:

The succulent evergreen tree Euphorbia stenoclada (“samata”) is the most important dry season fodder resource on the coastal plains grazing grounds in the Mahafaly Plateau region. To increase production, samata can be vegetatively propagated with cuttings raised in a nursery. The advantages are: (a) protection against livestock, (b) selection of the most appropriate planting stock to propagate and (c) easy watering. Cuttings should only be taken from mature trees 7-10 years old and 3-4 m high. The mother plants should be healthy, with few spines, and no previous cuttings taken. Cuttings are taken at the upper nodes of the branches, approximately 20-25 cm long and 0.5-1.5 cm diameter. Transport of the cuttings to the nursery should be carried out in the morning to avoid heat. For effective rooting, the cutting is planted 5 cm (1-2 nodes) into a humid substrate in a plastic pot or directly into the ground. Best results are achieved using white sea sand mixed with some organic material. Cuttings should be raised in a sunny location. During the first 15 days, the cuttings need to be watered once every morning. For the next 3-4 months, they need watering every second morning. 24 hours before transplantation from the nursery to the final destination, the cuttings should be abundantly watered. Rooted cuttings are transplanted into pits of 10 cm diameter and 15 cm depth, filled with the same substrate as used in the nursery. For 15 days, the transplants are watered on a daily basis, and afterwards every second day. After 30-45 days, the transplants are ready to survive without further care. If the planting location is open to roaming livestock, the cuttings need protection.

Purpose of the Technology: The samata tree naturally reproduces by seeds as well as by vegetative reproduction. However the German funded SULAMA research project has had most success with multiplication of the local variety with cuttings. This form of propagation is preferable as it is much faster and gives higher survival rates of the individuals: neither does it need much planting material, equipment or technical knowledge. Providing the villagers with the know-how, and assisting them to create local samata-nurseries, makes this technology promising. SuLaMa-WWF started this technique in April 2015, establishing 5 nurseries with 2,000 trees each (3 with village communities, 2 with local schools).

Establishment / maintenance activities and inputs: On the coastal plain of the Mahafaly plateau region, the climatic and edaphic conditions do not support livestock raising based mainly on grasses. For 6-7 months, the herders are dependent on supplementary fodder plants, especially samata. The tree is fed by cutting its branches and slicing them. However pressure on this resource has led to depletion of stocks around many villages: this results from increasing demand and reduced supply. Higher demand is the result of changed herd movements, especially a shorter transhumance period. Lower supply is attributed to decreased precipitation, overuse of trees leading to poor regeneration or even the death of trees, and reduced samata areas due to the expansion of private crop fields. The overuse of trees is triggered by the overall scarcity of this resource as well as an ongoing privatization of the historically common land resources.

4.1 Dibujo técnico de la Tecnología

4.2 Especificaciones técnicas/ explicaciones del dibujo técnico

Multiplication of samata trees through cuttings preferably in the cold season from June to August: (1) Selection of suitable mother plants: adult trees 7-10 years old, 3-4 m high, good phytosanitary condition, low in spines, without previous cuttings taken (2) Taking cuttings with a sharp knife at the upper nodes of the branches, approximately 20-25 cm long and 0.5-1.5 cm in diameter. To ensure the survival of the mother tree, at least 10 branches should remain uncut. Transportation of the cuttings to the nursery takes place preferably in the early morning to avoid heat. (3) Daily care of cuttings in nurseries till the roots are well-established. The cuttings are planted 5 cm deep (1-2 nodes) into a humid substrate in a plastic bag or pot, filled with a substrate of white ocean sand mixed with some organic material, for example dung (75% sand, 25% dung). During the first 15 days, the cuttings need to be watered once every morning. For the next 3-4 months, they need watering every second morning. Shade has to be avoided. (4) Transplanting cuttings: 24 hours before transplanting, the cuttings need to be abundantly watered. The rooted cuttings are transplanted into holes of 10 cm diameter and 15 cm depth, filled with the same substrate used in
the nursery. For 15 days, the transplants are watered on a daily basis, and afterwards every second day. After 30-45 days, the transplants will be ready to survive without any further human attention.

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
Land users are interested in applying this technology, as the samata tree is their main dry season fodder plant and overuse and scarcity today is severe How can they be sustained / enhanced? Providing land users with the technical knowledge and know how about samata propagation.
‘Artificial’ propagation of samata by vegetative multiplication (cuttings) does not require any special equipment or much specific knowledge.
Increasing the number of trees on the grazing land, and decreasing the pressure on trees enlarges the crown diameter of trees, thus providing additional shade for wild and domestic animals.

6.8 Debilidades/ desventajas/ riesgos de la Tecnología y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
Land users are unaware that ‘artificial’ propagation through cuttings is possible	Spread this knowledge.
The cuttings need constant care, as they need to be watered frequently over many weeks. This requires attention and labour	The long-term benefits outweigh the labour invested.
