2. Description de l'Approche de GDT

2.1 Courte description de l'Approche

The unsustainable use of pastures and forest areas leads to erosion, degradation, desertification and loss of biodiversity in high mountain areas of the South Caucasus. In the village Ehen in the Ismayilli district in Azerbaijan, a community-based approach for erosion control was developed in a participative way. Together with village stakeholders, different measures were developed to stop erosive processes, flooding and to rehabilitate vegetation cover.

2.2 Description détaillée de l'Approche

Description détaillée de l'Approche:

The Ministry of Ecology and Natural Resources of Azerbaijan togehter witht the Deutsche Gesellschaft fuer Zusammenarbeit (GIZ) selected integrated erosion control as a priority in their cooperation and the district Ismayilli was choosen for the implementation of pilot activities.
The district Ismayilli covers an area of about 2.158 km². Approximately 31% of the territory is covered with forest. Pasture lands on slopes are particularly exposed to vegetation degradation due to overgrazing. The loss of a closed vegetation cover on mountain slopes can lead to severe soil erosion due to surface water runoff. The project team together with the district administration decided to set the focus on the village Ehen near Lahic.

The approach chosen for integrated erosion control in Ehen was a community-based approach. Together with stakeholders, the most severe erosion sites were identified, and a list of priorities was developed. In cooperation with international experts, different technologies and practices were developed to stop erosion processes. Several preconditions for the development of a number of practices were set: The technologies should be cost-effective and affordable for the villagers, and the villagers should be able to use them without the use of external technicians. In order to achieve this, particular emphasis was placed on the application of bio-engineering measures. Measures were applied on degraded pasture lands and erosion gullies in the pilot community at the south slope of the Great Caucasus.

As a first step, the implementation sites were determined through joint field visits by village representatives and experts ('Screening mission'). In the first face the GIZ-team and the SLM-experts have been introduced to the village community. In this phase, the national GIZ project coordinator had the major role to create a basis of respect and trust to enable a positive athomisphere for an open minded discussion. The driving factors of deforestation and overgrazing were discussed in the field, and the potential intervention sites were marked with colour spray and wooden poles in the field. The marking in the field instead of only working with printed maps was very important for the recognition, discussion and acceptance of the sites by all villagers. There was a gap of several weeks between marking and implementation, which provided enough time for internal discussion about the site selection and the adaptation of boundaries.

Nine degraded pastures and forest land sites were selected by the village stakeholders togehter witht the SLM specialists. Four sites are located above the village with the risk of increasing rockfall and flooding by surface water runoff. Five sites are located below the village and were selected to ensure the productivity of the land. For providing tree seedlings, a local tree nursery was established near the school (10th site). One site was selected to combine effects by establishing a hazelnut plantation to stop erosion, increase vegetation cover and provide an income generation opportunity.
Two sites with gully erosion were selected: a site above the village with the risk of flooding into the village and a site below the village along the road with a high risk of road damage if the deepening process continues (detailed instructions on measures can be found at the internet links attached).
Regular meetings took place between the traditional administrative community board, the GIZ-project team and the SLM experts to discuss the implementation process and to evaluate together the results. The availability of local resources was taken into consideration to adapt technologies to fit the local needs. New ideas, localy available materials and technologies have beein integrated into the implementation process by the local stakeholders.
The implementation of the measures was done mainly by the local village people and local experts. The SLM experts provided 'hands-on-training' and all materials that were not available in the village as well external experts were financed by the project.

Another essential aspect is the sustainable use of well-managed meadows by different stakeholders (beekeepers, wild herb collectors, orchard owners and others) in the community. This includes the agreement (rule) of the community to share the protected pastures and to consider the needs of all interest groups. The decission of the profit sharing is taken by the taditional administrative community board. A further factor was the establishment of a tree nursery, which led to an increased motivation to plant additional trees (especially fruit trees) in the community.

2.7 Type d'Approche

  • fondé sur un projet/ programme

2.8 Principaux objectifs de l'Approche

Develop erosion control measures that can be implemented by village population without significant investment. The measures are addressed to rehabilitate vegetation on eroded sites and to slow down water speed and erosive energy where gullies already exist. This should help protect roads and other infrastructure as well as stop soil loss and increase overall productivity.

2.9 Conditions favorisant ou entravant la mise en œuvre de la(des) Technologie(s) appliquée(s) sous l'Approche

normes et valeurs sociales/ culturelles/ religieuses
  • favorise

Local population tend to save resources such as forest and pasture surrounding their village. Residents, especially women collect wild plants to use in daily life. Furthermore, selling collected wild plants in the market, residents earn income.

disponibilité/ accès aux ressources et services financiers
  • favorise

Most of the activities (fencing, willow fascines, pilewalls, gabion or wooden check dams) only need small-scale financial investments. Only the drip irrigation system for the hazelnut orchard needed significant external investment, and the return of the investment cannot be expected before 10 years. Such an investment would have been impossible for the village community without external support.

cadre institutionnel
  • favorise

The Community Management Group was established at the early stage of the project.

collaboration/ coordination des acteurs
  • favorise

Pilot activities are implemented in cooperation with local decision makers and communities. The active involvement of the village people in the implementation works was a hands-on training.

cadre juridique (régime foncier, droits d'utilisation des terres et de l'eau)
  • entrave

The forest’s legal protection does not allow timber or poles to be taken from the forest for the construction of pile walls or wooden check dams. The poles had to be imported and transferred to the village. A balanced sustainable forest management would enable village people to make use of the local timber and would encourage people to establish forest areas.

cadre politique
  • favorise

The Azerbaijan policy to establish more than 2000ha of hazelnut orchard in the district of Ismayilli supports the decision to establish hazelnut orchards on eroded sites as a control measure.

gouvernance foncière (prise de décisions, mise en œuvre et application des décisions)
  • favorise

Pilot sites are located in municipality land. Community members and local authority decided the border of pilot sites.

connaissances sur la GDT, accès aux supports techniques
  • favorise

Residents have some initial knowledge of sustainable land management. Implementing pilot activities their information is developed.

marchés (pour acheter les intrants, vendre les produits) et prix
  • favorise

Collected wild plants are sold in the market located next to Ehen village.

charge de travail, disponibilité de la main-d'œuvre
  • favorise

The manpower is available in the village

6. Analyses d'impact et conclusions

6.1 Impacts de l'Approche

Est-ce que l'Approche a autonomisé les exploitants locaux des terres, amélioré la participation des parties prenantes?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

The application of easy-to-use measures for erosion control enabled local land users to arrange land management and erosion control measures by themselves without relying on significant external support. The pilot actions in the village Ehen are used as a showcase for the neighbouring villages.

Est-ce que l'Approche a aidé les exploitants des terres à mettre en œuvre et entretenir les Technologies de GDT?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

As a result of the on-the-job training, most of the activities (fencing, pile walls, hay mulch application, wooden and gabion check dams) can now be implemented by the local village stakeholders without external support.

Est-ce que l'Approche a mobilisé/ amélioré l'accès aux ressources financières pour la mise en œuvre de la GDT?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

International funds were accessible for the village community and other international donors funded measures in the same village.

Est-ce que l'Approche a amélioré les connaissances et les capacités des exploitants des terres pour mettre en œuvre la GDT?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

The involvement of local stakeholders in all stages of planning, site selection and implementation improved capacity and knowledge. It was very important that the work was done mainly by local village people and not by external companies.

Est-ce que l'Approche a amélioré les connaissances et les capacités des autres parties prenantes?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

University experts and district-level technicians participated in the planning and implementation. They can act as knowledge hubs.

Est-ce que l'Approche a atténué les conflits?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup
Est-ce que l'Approche a conduit à améliorer la sécurité alimentaire et/ou la nutrition?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup
Est-ce que l'Approche a amélioré l'accès aux marchés?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup
Est-ce que l'Approche a conduit à des emplois, des opportunités de revenus?
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

Villagers have reported that the improved vegetation in the fenced areas led to significantly higher honey harvest and herb collection for marketing on the bazaar of Lahic village.

Protection from national hazards:
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

All gabions at the sites in Ehen are functioning well and show the impact of the gully deepening and the wash out at the lower (downhill) end of the gabion. Reduced water speed and the stabilised river bed helped to save the road.

Economic impact and improvement of livelihoods via ECM (Erosion control measures):
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

In the pilot sites, main economic activities are haymaking, the collection of wild plants, beekeeping and harvesting of nuts (hazelnuts and walnuts). Since there is no more overgrazing in the pilot areas, the plant’s biodiversity is expected to continue increasing, so the bees tend to pollinate more often in these areas. Conducted analyses during the project show that local population would benefit from 97.770 AZN per hectare (97.770 AZN = 57.334,7 USD (as per 01.10.2018)) in the period of 15 years because of the net income coming from beekeeping, haymaking, the collection of wild plants and harvesting of hazelnuts.

Sustainable Land Use:
  • Non
  • Oui, un peu
  • Oui, modérément
  • Oui, beaucoup

The approach helps to mitigate land degradation by surface erosion. Hay making, forestry and hazelnut production have been supported as alternative land use on the rehabilitated land. Up until now, only pilot measures have been implemented on limited areas of the village area.

6.2 Principale motivation des exploitants des terres pour mettre en œuvre la GDT

  • augmenter la production

Improved vegetation, soil fertility and productivity of the land.

  • augmenter la rentabilité/ bénéfice, rapport coûts-bénéfices

The planting of hazelnut trees addressed reduction of erosion and as a second priority the production of hazelnuts for economic purposes.

  • réduire la dégradation des terres

Pasture lands on slopes which were exposed to the degradation of vegetation caused by overgrazing. Now grazing is blocked by fencing, and the land use was changed to either hay production, forest or hazelnut production.

  • réduire les risques de catastrophe

Gully erosion parallel to the road and further erosion of the gully’s left side which led to destruction of the road. The villagers are reporting that no rock falls and flooding were observed in the years 2017 and 2018 after the application of measures on site 1 above the village.

  • conscience environnementale
  • améliorer les connaissances et compétences en GDT

6.3 Durabilité des activités de l'Approche

Les exploitants des terres peuvent-ils poursuivre ce qui a été mis en œuvre par le biais de l'Approche (sans soutien extérieur)?
  • oui
Si oui, décrivez de quelle manière:

Local stakeholders trained on building and applying measures. The measures (fencing, pile walls, wooden and gabion check dams) are low-cost and can easily be replicated by village stakeholders. Only the drip irrigation system and electric fencing for the hazelnut orchard needs high investment and might not be up-scaled without external support.

6.4 Points forts/ avantages de l'Approche

Points forts/ avantages/ possibilités du point de vue de l'exploitant des terres
The integration of local stakeholders in the selection of measures and sites helped to address the most 'urgent' problems from the villagers view.
It was important to have visual results from the work in a short time. Especially the reduction of flooding was a very positive result as well as the increased number of flowering plants which led to an increase of honey and tea production, which created additional income. Some of the trained techniques have been already transferred by villagers to neighbouring communities.
Most of the beneficiaries see the hazelnut plantation area as a potential source of income in the future and at the same time as a useful measurement for rehabilitation of the biodiversity and measure against erosion.
Land users see the implementation of the measures on the site as contribution to the future tourism perspective of the village.
The pilot measure is cost-efficient and affordable for local people. It has a positive ratio of cost/benefit.
Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
Measures are easily implemented and materials (mesh wire, willows, seedlings) are available locally.
The measures are showing significant impacts in a short time. The rehabilitation of vegetation and the gathering of sediments halting gully deepening is already visible in the first year after implementation.
As there is still enough pasture land available and the areas of intervention have been implemented on degraded land, there was no major conflict with shepherds and farmers.

6.5 Faiblesses/ inconvénients de l'Approche et moyens de les surmonter

Faiblesses/ inconvénients/ risques du point de vue de l’exploitant des terres Comment peuvent-ils être surmontés?
Low capacity of the municipality was limiting to the management of the drip irrigation and the electric fence. Handing over the hazelnut orchard to a private cooperative could increase ownership and personal involvement of local stakeholders in orchard maintenance. A long-term business plan and financing model needs to be developed if the approach is to be up-scaled.
Current electric fence of hazelnut plantation is not efficient in protecting area from free roaming animals.
It also reflects on the inefficiency of the overseer`s working time, as he spends entire working hours on the controlling the fence which reduces his time on spending on the additional activities like controlling plant growth and irrigation system.
Changing electrical fence to the ordinary mesh fence or wire fence.
Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé Comment peuvent-ils être surmontés?
Because of a general ban on forest management, the timber used for pile walls and wooden check dams cannot be extracted from the local forest. Timber and logs have to be bought from foreign markets. An adaptation of laws on the legal extraction of local timber for certain purpose would be helpful.
Hazel needs more than 750 mm annual precipitation. Humidity above 60% in June and July is beneficial. A strong wind is a danger for young trees. Ehen has 500-700m precipitation and significant summer drought. A drip irrigation system was applied to overcome summer drought in the first couple of years until seedlings have established a sufficient root system to access water from deeper soil layers.
The electric fencing and the drip irrigation for the hazelnut plantation and fruit tree plantations above the village need expensive investment and specific skills for mounting and maintenance. Project investment was used for pilot measures as a demonstration site. The hazelnut orchard can show a positive return on investment within 10-15 years if managed well.
