2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Fencing part of an overgrazed hillside, combined with terracing, manuring and supplementary irrigation for grape, fruit and grass production.

2.2 Descripción detallada de la Tecnología

Descripción:

In the Varzob valley of Tajikistan, slopes of around 30% are used communally, and are heavily overgrazed. This has led to a reduction in vegetation cover, to soil compaction, and to severe sheet and rill erosion. In 1982, one innovative land user began to set up half a hectare vineyard/fruit plot with intensive grass/fodder production for cut-and-carry and also a separate section above for hay making - by his own initiative. By the application of various conservation measures, within five years an area exposed to severe water erosion was converted into an area of sustainable use. Fodder and fruits are now flourishing and the natural resources of soil and water are conserved more effectively.

Purpose of the Technology: The start of the process was fencing of the plot to keep out animals. Scrap metal and other materials from a machinery depot were used to build a 1.5 m high fence. To harvest and hold runoff water from the hillside for grapes and fruit trees, narrow backsloping terraces were constructed, each with a water retention ditch along the contour. During the initial phase, the terraces did not harvest enough water for establishment of the seedlings. So water for supplementary irrigation was carried to the plot by donkeys in old inner tubes from car tyres. Manure is applied to the plot to improve soil fertility. The manure is collected on the high pastures where the herders graze their animals during summer. The total amount of manure applied to the plot so far amounts to about 3 t/ha over 20 years.

Establishment / maintenance activities and inputs: The establishment of such a plot is very demanding in terms of manpower. However within 5-6 years the system becomes self-sustaining and the productivity of the land is improved several times over. Following this positive experience, other households in the area have adopted the technology spontaneously, and today about 15 ha of degraded grazing land in the Varzob valley have been converted into productive fruit gardens.

Natural / human environment: For the innovator, his most valuable fruits are grapes, followed by apricots, almonds and plums. He has also successfully grown mulberry, pomegranate and cherry trees. Not all the seedlings survive: the farmer considers a 40% survival rate of grape vines to be reasonable. The fruit harvest is mainly used for home consumption. However, in a good year the table grapes and apricots are sold on the market. The hay harvest, from naturally regenerated grasses and fodder plants between the fruits amounts on average to 0.2 t/ha/year. The pruned branches from the vines are collected and used as firewood.

Comentarios:

Labour cost per day is US$2. The fence constructed by the farmer was free because he utilised scrap from a machinery depot. Note that the total length of fencing is relatively less for a larger plot. In the villages, almost no money changes hands: there is a barter system between the farmers. Even salaries are often paid in terms of fruits, wood or free rent of land.

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
Rehabilitation of degraded areas: reduced soil erosion and increased productivity How can they be sustained / enhanced? Complement manure inputs by using other fertilisers.
Production increase: good fruit yields How can they be sustained / enhanced? Introduce low input demanding crops
Diversification: different kinds of fruit trees growing on the plot How can they be sustained / enhanced? Other trees (nuts for example) and annual crops such as wheat might also be suitable for this area.
Income generation.
Where open access communal grazing leads to land degradation, individuals sometimes enclose land for productive purposes. This positive example is from Tajikistan where the initiative began during the period of the soviet regime. Similar initiatives can be seen in western Iran. However, if a significant number of land users follow suit, there will be a reduction in the amount of land available for common use. 2.6.11: Level of technical knowledge required: land user: partly moderate (construction of terraces) and partly low (simple knowledge of agronomy, manure application, harvesting etc)

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?
Bringing water for supplementary irrigation to the orchard is very labour intensive	An irrigation supply system could be installed (irrigation channels, water tank). But so far this is too expensive, and it is questionable whether irrigation could be installed and maintained sustainably
Not all tree species can grow in these dry conditions (for example apple trees will not survive without regular irrigation or watering)	irrigation water required (see above).
Difficulty in establishment of the young vines in the well developed grass	Remove or cut down grass and herbaceous plants around the vines at least until they have been well established.
Generally high manual labour input	Difficult to reduce labour inputs.
