Freshwater transport from local streams for irrigation purposes, in order to replace the traditional form of irrigation (by pumping saline groundwater from wells).
- Compiler: John Gkiougkis
2. Description of the SLM Approach
2.1 Short description of the Approach
Use of freshwater to combat soil salinization.
2.2 Detailed description of the Approach
Detailed description of the Approach:
Aims / objectives: Freshwater transport from surface streams/rivers in order to remediate saline soils.
Methods: Freshwater flushing/irrigation on saline soils.
Stages of implementation: 1) License from local authorities for surface water consumption. 2) License from local electricity provider. 3) Installation of water-pump. 4) Installation of water transport network. 5) Installation of water irrigation sprinklers.
Role of stakeholders: Awareness of local authorities concerning the problem in order to accelerate the issue of the licenses for freshwater exploitation.

2.7 Type of Approach
- traditional/ indigenous
2.8 Main aims/ objectives of the Approach
The Approach focused on SLM only
Remediation and prevention of soil salinization. Local farmer motivation in order to adopt the SLM technology.
The SLM Approach addressed the following problems: 1) Depending on the pump type (diesel or electric), operational cost is subject to current oil-electricity price. 2) Freshwater not appropriate for sodic type soils reclamation (may enhance soil degradation). 3) Licenses for water pumping from surface streams are subject to bureaucracy. 4) Lack of cash to invest, due to recent economic crisis.
2.9 Conditions enabling or hindering implementation of the Technology/ Technologies applied under the Approach
social/ cultural/ religious norms and values
- hindering
Treatment through the SLM Approach: Appropriate management and control of water usage is required
availability/ access to financial resources and services
- hindering
High equipment cost (water pump and water transport network) and operational cost especially for diesel pumps.
Treatment through the SLM Approach: Government or EU funding for the purchase of the equipment. Replacement of existing diesel pumps with electric and more economic pumps.
institutional setting
- hindering
Bureaucracy for licensing.
Treatment through the SLM Approach: 'Fast track' policy implementation.
legal framework (land tenure, land and water use rights)
- hindering
There is a regulation concerning surface water transport which limits the transportation distance to 500m from nearby streams/rivers.
Treatment through the SLM Approach: Since there is sufficient surface water, the transport distance (500m) can be increased up to 2km in order to extend the area irrigated with freshwater and constrain the area which is irrigated by saline groundwater.
The existing land ownership, land use rights / water rights moderately hindered the approach implementation There were some restrictions on water rights (transport distance from irrigation/drainage canals is limited up to 500m).

3.4 Decision-making on the selection of SLM Technology/ Technologies
Specify who decided on the selection of the Technology/ Technologies to be implemented:
- mainly SLM specialists, following consultation with land users
Explain:
After a thorough soil analysis and taking into account fresh-water availability in the area, SLM specialists agreed with land users upon the appropriate SLM technology.
Decisions on the method of implementing the SLM Technology were made by mainly by SLM specialists with consultation of land users. As 2.1.5.1.
4. Technical support, capacity building, and knowledge management
4.1 Capacity building/ training
Was training provided to land users/ other stakeholders?
Yes
Specify who was trained:
- land users
Form of training:
- on-the-job
- farmer-to-farmer
- demonstration areas
- public meetings
- courses
Subjects covered:
Discussion with local farmers to realize the extension of the problem and the remediation strategies.
4.2 Advisory service
Do land users have access to an advisory service?
Yes
Specify whether advisory service is provided:
- at permanent centres
Describe/ comments:
Name of method used for advisory service: Discussions ; Key elements: In-situ discussions, Public debates, Demonstrations
Advisory service is inadequate to ensure the continuation of land conservation activities; More funding needed as initiative.
