2.1 Descrição curta da tecnologia

Definição da tecnologia:

Vegetative and structural technology for the rehabilitation of an expanded gully

2.2 Descrição detalhada da tecnologia

Descrição:

The extension of a deep incised gully, which borders a fertile orchard, is stopped and sediments are trapped by the help of vegetative and structural measures. The gully floor is vegetated with different trees inter alia willow, poplar, cherry, blackberry and walnut which are arranged in random groups. At the bottom of the gully where it intersects the road there is a stonewall, which collects the sediments that are washed down during heavy rainfalls mostly in spring. A dense bush line with Russian olives, apricots, cherries, walnuts, plums and buxus has been planted on the top of the side slopes of the gully, and roots of those bushes keep the soil stable and at the same time they prevent landslides and expansion of the gully. These tree lines are cut from time to time, otherwise they grow and become heavy and due to their weight the trees would possibly fall into the gully.

Purpose of the Technology: (1) The deep roots of willow trees on the bottom of the gully protect the soil and prevent it from being eroded during the heavy spring floods. Trees also help to collect sediment and to accumulate it in the gully. (2) The dense bush lines with its deep roots, on the top of the gully slope, stop the horizontal erosion, which endangers the fertile orchard close to the gully. (3) A stonewall at the lower end of the gully collects sediments which have been washed down. Once in a while a heightening of the stonewall has to be done. The technology with its three measures prevents from further gully expansion and supports its rehabilitation.

Establishment / maintenance activities and inputs: These three measures, the tree line, the bottom vegetation and the stonewall were developed and implemented by the farmer's own initiative. The farmer implemented the technology on his own and expands it every year. The entire technology doesn’t have to be established at once, which allows investing money and time whenever it is available. For maintenance new trees are planted both in the gully and in the tree line, which has to be cut and pruned from time to time. The technology is relatively affordable and facile to implement. At the beginning the farmer bought some seedlings. Meanwhile, the plants reproduce themselves and the farmer doesn't have to buy seedlings for further maintenance. The stones can be collected for free in the nearby riverbed. The work is done manually; no special tools are needed for the technology.

Natural / human environment: The farmer is proud of the outcome of his initiative. However he wishes that his neighbours would follow his lead, as for them it would be beneficial to implement the technology as well. He stated that usually people do not listen to a common farmer, but if the technology would be introduced by an official person it would spread out quickly.

3.7 Principais tipos de degradação da terra abordados pela tecnologia

Comentários:

Main type of degradation addressed: Wg: gully erosion / gullying

Secondary types of degradation addressed: Wm: mass movements / landslides, Wr: riverbank erosion

Main causes of degradation: soil management (lack of knowledge for soil treatement, e.g. people dig hollows which support gully formation, agronoms from soviet times are missing), over-exploitation of vegetation for domestic use (Trees were cut for domestic use), overgrazing, disturbance of water cycle (infiltration / runoff), Heavy / extreme rainfall (intensity/amounts), land tenure (land is not private property), poverty / wealth (no money for tractors, fertilizers, education, etc.,), education, access to knowledge and support services, war and conflicts (during the civil war the land was not cultivated sustainably), governance / institutional (land use rights)

Secondary causes of degradation: deforestation / removal of natural vegetation (incl. forest fires), change in temperature (too hot and too cold temperatures dry out the soil, plants cannot survive), change of seasonal rainfall, population pressure, inputs and infrastructure: (roads, markets, distribution of water points, other, …) (lack of machinery to treat the field properly)

Comentários:

The fact that the inputs for the technology are not evenly distributed throughout the area, the costs were calculated for the whole technology area.

4.7 Fatores mais importantes que afetam os custos

Descreva os fatores mais determinantes que afetam os custos:

The material is relatively affordable. Money intensive factor are the seedlings during establishment phase. Following years the trees reproduce themselves. The establishment of the technology, the planting of the trees and the building of the stonewall require a lot of labour input in the initial phase. As the whole technology does not have to be implemented at once, the work can be split-up over years.

Caso disponível anexe a descrição completa do solo ou especifique as informações disponíveis, p. ex. tipo de solo, PH/acidez do solo, nitrogênio, capacidade de troca catiônica, salinidade, etc.

Soil depth on average: No soil in the gully

Soil fertility is medium for the treeline on top of the slopes of the gully (close to the orchard). but in the gully its very low because the soil was washed away.

Topsoil organic matter is medium at the treeline on top of the gully slope.

Soil drainage / infiltration is medium and in the orchard, gully works as drainage

Soil water storage capacity is very low

Annual population growth: 2% - 3%

10% of the land users are rich (trader which buy and sell products from the farmers).
60% of the land users are average wealthy and own 80% of the land.
30% of the land users are poor and own 20% of the land.

Comentários:

On the bottom of the gully willow trees should be planted which have strong roots to resist floods, especially if the gully is already deep. At the slopes Russian olives and wild cherries can be planted. The higher amount of trees makes gully even more stable.

Como os benefícios se comparam aos custos recorrentes/de manutenção(do ponto de vista dos usuários da terra)?

Comentários:

Much more extra work comes up for the establishment, but for the farmer work is not a disadvantage.

6.5 Adoção da tecnologia

Comentários:

There is a little trend towards spontaneous adoption of the Technology

6.7 Pontos fortes/vantagens/oportunidades da tecnologia

Pontos fortes/vantagens/oportunidades na visão do usuário da terra
Stopping the expansion (prevention) of the gully and filling up the gully (rehabilitation). How can they be sustained / enhanced? Maintain the vegetative measures, plant more seedlings and let them reproduce themselves.
Firewood and construction material production. How can they be sustained / enhanced? Increase the vegetation with wood of good quality and use it in a sustainable manner (cut only as much as will be reproduced).

Pontos fortes/vantagens/oportunidades na visão do/a compilador/a ou de outra pessoa capacitada
Extensive use of the area and a relatively rich diversity of local vegetation. The maintained gully provides new habitat for natural flora and fauna. How can they be sustained / enhanced? Keep and promote the diversity of plants in the gully.
Cheap and relatively less labor intensive work. Relatively little knowledge and no special tools are required. How can they be sustained / enhanced? Make the technology public.
The entire technology doesn’t have to be established at once, which allows investing money and time whenever it is available.

6.8 Pontos fracos, desvantagens/riscos da tecnologia e formas de superá-los

Pontos fracos/desvantagens/riscos na visão do usuário da terra	Como eles podem ser superados?
The trees stop the water, sediments, branches etc. too effectively and this creates problems with too much water in the gully, which is washing out the sides of the gully.

Pontos fracos/vantagens/riscos na visão do/a compilador/a ou de outra pessoa capacitada	Como eles podem ser superados?
A disadvantage is the extra work the farmer have to spend on a little productive area.	In the land users view work is not a disadvantage, it is his job. Considering the fact that it is not that much extra work, it is not a big disadvantage.
For the establishment a first investment for the seedlings is required.	An establishment of the technology during a longer period allows to grow own seedlings from the plants which do not cost anything.
