2. Descripción de la Tecnología MST

2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Terraces are established on mountain slopes used mainly for cropping wheat, with the purpose of soil protection from erosion, preserving runoff, sediments and nutrients on-site. Improved seeds and fertilizer are applied on the terraces for increasing crop yield, but also vegetation cover and biomass production, and thus prevent further land degradation.

2.2 Descripción detallada de la Tecnología

Descripción:

Project supported implementation of terraces with application of improved seeds and fertilizer has taken place in the villages Sari Joy, Jawaz Khana and Dashti Mirzai, located in Chokar watershed of Rustaq District in Northern Afghanistan. The Chokar watershed is a mountainous area situated between 600 - 2,500 m above sea level. The climate is semi-arid with harsh and cold weather in winter and hot and dry summers. The annual precipitation in average years is 580mm. Land degradation affects all forms of land use and includes low vegetation cover, heavy top soil erosion from water, and poor soil fertility. Unsustainable agricultural practices, over-exploitation and high pressure on the natural resources are adversely impacting on the socio-economic well-being of local communities as well as contributing to the risk for being adversely affected by drought as well as landslides and flash floods triggered by heavy rainfall.
The data used for the documentation of the technology is based on field research conducted in Chokar watershed, namely in the villages: Sari Joy, Jawaz Khana and Dashti Mirzai. These villages represent the upper, the middle and the lower zone of Chokar watershed, respectively. They differ considerably in access to services and infrastructure, but in general are poorly served. The communities depend mainly on land resources for sustaining their livelihoods. In a good year with high yields, wheat-self-sufficiency lasts about 5 months.
Since 2012 the Livelihood Improvement Project Takhar (LIPT) implemented by Terre des hommes (Tdh) Switzerland has initiated a range of NRM interventions. The project introduced terraces as sustainable land management practices on private plots, situated on rolling (11-15%) and hilly (16-30%) slopes to protect the land from soil erosion and prevent the loss of water and fertile topsoil, seeds and fertilizers. The average plot size for terrace implementation is 2 Jerib (0.4 hectares) with contour strips of 40m x 4m. The height of the risers is 1m-1,5 m. Terrace benches are built along the contour by moving the soil above the bench downwards. The leveled benches of the terrace are cultivated with wheat. The risers of the terrace are mostly used for growing fodder crops, mostly alfalfa, which also helps to stabilize the terrace. If medicinal herbs (ferula) are included they are cultivated along the bench contours .
Maintenance activities include small repair work on the riser by adding some amount of soil and re-sowing of alfalfa seeds on those spots.
The terraces allow application of improved seeds and fertilizers without them being washed off. The land-users report noticeable increase of wheat yield from the terraced plot with application of improved seeds and fertilizer compared to the non-terraced plot. An average plot of 0.2 ha on non-terraced hilly cropland used to give about 70 kg of wheat (350kg/ha). On terraces the yield has increased/ doubled to 140 kg on the same plot area (700kg/ha). The expectations regarding terraces remain high as over the time the land user hope their land will become more stable and improved soil moisture and fertility will have positive impact on the productivity as well. However, so far no cost-benefit assessment has been conducted allowing attribution of individual measure to the wheat increase.
Many land users are interested in the terrace technology due to a number of environmental and economic benefits expected, however the costs for building the terrace are considered high by an average local land user. They have to rely on external support in order to have sufficient resources for implementation. Women considered an advantage that during the establishment phase, men were paid by the project to work on their own land (or other villagers land) when building the terraces. Thus, there was no need for men to go for seasonal labour migration and they stayed at home.

4. Especificaciones técnicas, actividades de implementación, insumos y costos

4.1 Dibujo técnico de la Tecnología

Especificaciones técnicas (relacionadas al dibujo técnico):

Terraces are established predominantly on a privately owned land in a mountainous landscape with varying steepness of slopes.
The average size of a plot is 2 Jerib, which is equal to 0.4 ha. The design of the terrace depends on the steepness of the slope. Mostly rolling (11-15%) and hilly (16-30%) slopes are used for building terraces.
Using an A-frame, the terrace is designed by dividing the slope into contour strips. Depending on the slope steepness, the terrace bench is around 4m wide and the the height of the risers is 1m-1,5 m. The terrace benches are built along the contour by moving the soil of upper bench to the lower bench. The leveled benches of the terrace are cultivated with wheat. The risers of the terrace are mostly used for growing fodder crops, such as alfalfa, which also helps to stabilize the terrace. If medicinal herbs are included, such as ferula, they are cultivated along the bench contours.

Comentarios:

Based on the multi-criteria matrix: SLM implementers from three villages were asked to jointly discuss and rate how much the SLM technology reduced the lands vulnerability to drought and local rainstorms. Only vulnerability to the most prevalent climate extremes (drought and local rainstorms) was discussed. SLM technologies were rated as reducing vulnerability poorly , well, or very well. The average points reflected here are from multi-criteria matrices compiled in three villages where the SLM technology had been implemented.

6.4 Análisis costo-beneficio

Comentarios:

Costs: As larger parts of the establishment of the technology were covered by the project, farmers consideration of the total costs are likely underestimated.
Benefits: Two plots were terraced in 2012, and 5 plots in 2013. However, most terraces were implemented in 2014 (11 plots ) and 2015 (8 plots). The Rustaq NRM study was conducted in autumn 2016. 1-2 years of cultivating the terrace system is too short a period for providing evidence on short- and long-term returns.

Especifique la adaptación de la Tecnología (diseño, material/ especies, etc.):

Ferula is planted on the terrace in addition to wheat and alfalfa. The resin-like gum from the dried sap extracted from the stem and roots of Ferula is in high demand as a basic product for pharmaceuticals. Ferula can be sold to local merchants, who resell it to India, and is thus intercropped by some farmers on the terraces.

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del usuario de la tierra
Notable higher crop yields on the plots where improved seeds and fertilizer are applied on newly established terraces. Farmers have high expectations for the years to come and for yields of annual crops (such as wheat) to remain high.
Diversity of crops planted on terraces is valued by the land users. For example, cultivating wheat and alfalfa on the terraced plot provides household with the key crop and also fodder for the livestock and thereby contributes to securing food for the family and maintaining better health of their cattle. Additionally, some farmers have started intercropping Ferula, a medical herb and cash crop.
Farmers percieve soil quality on terraced plots with fertilizer application to improve. An improvement in soil fertility (which may relate first of all to the effects of fertilizer application) and increased soil moisture have been reported. Single statements also related to effectiveness of applying fertilizer on terraced plots, as here fertilizer is not washed away during rains.
Terraced plots are considered less vulnerable to the effects of rainstorms and dry spells, than non-terraced plots on slopes where annual crops are cultivated.
Women considered an advantage that during the establishment phase, men were paid by the project to work on their own land when building the terraces. Thus, there was no need for men to go for seasonal labour migration and they stayed at home. At the same time the terracing of the land is seen as an opportunity to improve the land resources on their families plots. An increase in women's workload related to bringing food to the field during establishment was considered to be acceptable, especially compared to the expected increase in yields.

The application of fertilizer on terraces is expected to show multiple effects: yields from these fertility depleted croplands can be increased. This includes an increase in biomass production, which may be used as green manure on the field or as animal feed or as straw. Further, vegetation cover during the growing period can be increased, which helps to protect the soil from erosive rains.
The project paid establishment of terraces on farmers' plots provided 20 days of employment per 2 jerib (0.4 ha) plot for farmers in their home villages. At the same time the terracing is a long-term investment into the land resources. Terracing provides an opportunity to decrease soil degradation and even to rehabilitate degraded lands. Application of improved seeds and fertilizer contribute in the establishment year to increased crop and fodder yields.

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

Debilidades/ desventajas/ riesgos desde la perspectiva del usuario de la tierra ¿Cómo sobreponerse a ellas?
The implementation costs are high and land users state that it is impossible for them to cover establishment costs on their own.
Farmers expectations partly exceeded the actual yield harvested from the terraces in the first years after the implementation.
Both men and women from households that have implemened terraces state that during the establishment year the household experiences an increased workload, that is not well compatible with other on-going household / farm activities.
The production area for annual crops only is slighty reduced. So far not all farmers seem to use the production area fully. Intercropping with perennial plants is recommended in order to use the risers of the terraces for fodder production. Some farmers have started intercropping of Ferula as cash crop.
Sufficient own land is required. How does the amount of cropland affect the innovation readiness of a farmer? A better understanding is required on farmers willingness to take a risk for investing in a new SLM technology, and especially terracing, and influencing factors.

The technology requires technical knowledge for implementation and maintenance, which is key for successful adoption, replication and upscaling. The project trained technicians to support land users with the design of terraces. While the project aided implementation of terraces has improved the general knowledge and awareness of the land users on the benefits of SLM practices, most farmers will not be able to design terraces on their own.
Technically correct design of the terrace presents a challenge and might not be always achieved. Forward sloping terrace benches may lead to channeled runoff and have the risk of rills and gully formation.
There is an attribution gap regarding the increased wheat yields, especially with regard to individual contribution of the terraces, the application of improved seeds and the fertilizer, and the combined effects (role of terraces in making improved seed and fertilizer application effective). A cost benefit analysis (CBA) needs to be conducted to determine short- and long-term returns of the SLM technology. On farm trials are necessary for assessing impacts of the different measures (agricultural, vegetative and structural measures) before-and-after, as well as with-without the SLM technology.
Terrace maintenance is crucial. If not maintained properly for a longer period of time, the damaged terrace can lead to further land degradation through channeled runoff, sever erosion and possible risks of disaster for the surrounding settlements on the slopes.
The technology is established mainly by better-off households, which own more land than the average SLM implementer.
