2.1 Breve descripción del Enfoque

Optimising rainwater use, reduce runoff by use of basins and reduce evaporation losses by applying a mulch (stone/reeds) on the runoff strip and in the basins.

2.2 Descripción detallada del Enfoque MST

Descripción detallada del Enfoque MST:

Aims / objectives: Given the marginal soils of a clayey nature and/or slope terrain, coupled with erratic rainfall events, the technology aims to harvest available rain water and prevent runoff and soil loss. At present, PRAs are conducted in target areas and so far, people are eager to adopt the technology. The aim is to train them and assist in constructing the basins so that after a year they will be able to take over the project entirely even though the team will still be around to provide advice should the need arise.

• proyecto/ basado en un programa

2.8 Propósitos/ objetivos principales del Enfoque

The Approach focused on SLM only (n/a)

*To make optimal use of pre-plant water that collects in basins from summer rains that fall during the fallow period. Saved water very beneficial during the reproductive growth of plants which often occurs when there is no rain.
*Prevention of soil and water loss through water erosion and runoff by the use of basins.
*Restriction of evaporation by the use of mulch. Straw is mostly preferred for its biodegradability although stone in comparative percentage cover is more effective.

The SLM Approach addressed the following problems: The target areas are marginal for crop production because of relatively low and erratic rainfall and dominantly clay soils on which the precipitation use efficiency is low because of high losses due to runoff and evaporation form the soul surface.

Especifique quién decidió la selección de las Tecnología/ Tecnologías a implementarse:

• solo por especialistas MST

Explique:

land user driven (bottom-up). Realisation of poverty.

Decisions on the method of implementing the SLM Technology were made by mainly by land users supported by SLM specialists. land user driven (bottom-up). The need of land users to alleviate poverty.

4.1 Construcción de capacidades / capacitación

¿Se proporcionó la capacitación a usuarios de tierras/ otras partes interesadas?

Sí

Especifique quién fue capacitado:

• usuarios de tierras

• extensionists/trainers

Forma de capacitación:

• áreas de demostración
• reuniones públicas

Temas avanzados:

Construction of basins; better understanding of the system in simple terms; the concept of infiltration, evapotranspiration; erosion and runoff.

4.2 Servicio de asesoría

¿Los usuarios de tierras tienen acceso a un servicio de asesoría?

Sí

Especifique si servicio proporcionado se realizó:

• en centros permanentes

Describa/ comentarios:

NDA Extension; Key elements: Assistance in technology transfer, Organising public meetings, Establishing & link between specialists and land users;
1) Advisory service was carried out through: government's existing extension system. Extension staff: mainly government employees
2) Target groups for extension: land users; Activities: Technology transfer

Advisory service is quite adequate to ensure the continuation of land conservation activities; With a little persuasion, they assist completely.

4.3 Fortalecimiento institucional (desarrollo institucional)

Especifique el tipo de apoyo:

• construcción de capacidades/ entrenamiento

4.4 Monitoreo y evaluación

¿El monitoreo y la evaluación forman parte del Enfoque?

Sí

Comentarios:

bio-physical aspects were regular monitored through measurements
socio-cultural aspects were None monitored through measurements
economic / production aspects were None monitored through measurements
There were few changes in the Approach as a result of monitoring and evaluation: An organic mulch can be placed in the basins and on the runoff strip to stop evaporation losses. However cattle are allowed to graze in the land after the crop has been harvested. There after there is almost no organic mulch left to cover the soil surface. Stones were then suggested as an alternative mulch.

6.4 Fortalezas/ ventajas del Enfoque

Fuerzas/ ventajas/ oportunidades desde la perspectiva del usuario de la tierra
Produced higher yields.

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
Success of the WHB technique depends on suppressing water losses by runoff (R) and evaporation from the soil surface (Es). Measurements show that R has been reduced to zero and that Es has been reduced considerable, but still remains a serious avenue for water loss. (How to sustain/ enhance this strength: Future experimentation needs to focus on suppressing Es by any possible means.)
The WHB treatment gives considerably better yields than the conventional treatment. (How to sustain/ enhance this strength: Results from more seasons are needed to quantify the extent of this difference in a reliable way.)
Save on cultivation costs since no-till is employed.
The WHB technique is ell suited for use on very small pots, and even in townships. Many people in semi-arid areas could be usefully employed if this technique was widely adapted, and food security could be increased at the same time. (How to sustain/ enhance this strength: Extension work in this connection by the PSDA needs to be encourage.)
Soil loss from the land as a whole is zero. This is an important advantage over the conventional tillage in terms of sustainability.

6.5 Debilidades/ desventajas del Enfoque y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del usuario de la tierra	¿Cómo sobreponerse a ellas?
It is labour intensive to initially construct the basins, by hand.

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
There is some soil movement form the runoff area into the basins, ad basins may silt up over time.
Huge storms may overflow and break basin walls; and basins may need some maintenance.
In the case of small rainfall events all the water may not reach the basins.
Organic mulch may act as a sponge and absorb some of the rainwater.
