2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Promotion of low-pressure drip irrigation kits among vulnerable women-led households in dry agrolandscapes of Southern Tajikistan has helped to fight desertification, improve food security and enhance economic opportunities.

2.2 Detailed description of the Technology

Description:

Low-pressure drip irrigation systems or Family Farm Drip Irrigation (FFDI) kits including water tanks and high-quality planting materials were distributed in the framework of an FAO project. The project aimed at enhancing food production by providing affordable irrigation solutions in dry and saline agrolandscapes of the Central Asian region. The FFDI systems were distributed to 60 women-led households in Khatlon province of Tajikistan. Additionally FFDI systems were installed in eight demonstration plots of organizations and state institutes. The beneficiaries were identified according to selection criteria to best contribute to food security and livelihood improvement through these affordable irrigation solutions. They were trained in irrigation and crop husbandry through a workshop, and their irrigation and plant production activities were monitored. Despite problems with pest management, vulnerable women-headed farms in the climate change affected areas increased crop productivity by 50% and harvested 2 crops a year. Vegetables were the crops of focus, and the average area irrigated was 300m2. Moreover, the application of the mulching helped to preserve more moisture and it helped to reduce irrigation norms by 25-30 per cent. For mulching, wheat straw and/or flax straw with a thickness of 7-10 cm was used. The FFDI system is affordable, does not require pumping, is easy to install and move, is easily adjustable and is supported by an installation kit. However, it does require relatively clean irrigation water. It is recommended to test expanded FFDI systems to continue the promotion of SLM and produce more food.

Strengths/ advantages/ opportunities in the land user’s view
The ToT training for promotors and best farmers on the topics of proper operation and maintenance of the drip irrigation systems were delivered to enable the active farmers from the different districts for continuing the promotion of the techniques.
The provided support of the project for most vulnerable families helped to increase family income and benefit from the crops yield increases and water is used with maximum efficiency, weeds cannot absorb water as it is not available for them. there are fewer weeds, soil infiltration capacity is increased, there is no soil erosion, applying water locally, leaching is reduced; fertilizer/nutrient loss is minimized.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Provision of the agriculture inputs for free can negatively affect the promotion of the best SLM techniques after the project life span. High investment costs can be one of the reasons for blocking upscaling. To find a co-financing source and/or to increase co-financing ratio by the farmers.
