 Water lifting technologies free the farmers from the limitations of inadequate rain during dry seasons, thus raising their capacity to grow crops up to two or three plantings annually. Thus, additional income possibilities for the subsistence economy of the households are provided.
-In addition, water efficient technologies such as pumps can bring an improvement to the situation of women by increasing household food security and nutritional variety, as well as decreasing the amount of labor required to obtain water. Most pumps can easily be operated by women.

 When comparing the advantages and disadvantages of various water lifting devices, it is important to focus on technical feasibility and sustainability in the context of the respective target region and target group.

 Additionally, most of the irrigation work that used to be the task of women and children can now be done by pump technologies. Therefore, due to the time saved by not having to fetch water, there has been an increase in school attendance by children, especially of girls. Children are healthier, because of less disease and thus more able to participate in classes, and also have more time for educational and social activities.

 A realistic assessment of cost effectiveness is not easy, particularly as many of the parameters required for such an analysis are frequently uncertain or variable. Also, many cost and benefit factors do not readily lend themselves to financial quantification: e.g. reliability, availability of spare parts, and maintenance skills.
-The initial investment cost depends on the device. The cost range for a treadle pump, including the tube well, is US$ 100-200 (depending on installation depth and drilling method). A ram pump, without pipes and hoses, is around US$ 150 (depending on the quality of the material and the size of the manufactured pump).

 Mechanical/alternative lifting devices, which are run without a power supply, become more attractive as the price of gasoline and electricity continues to increase, as the increased price of power reduces the profit margin of irrigation. The ram pump, which has been successfully implemented in remote areas in Central Asia where electrical supply is not sufficient, could also become a more attractive option to farmers in other regions.
@@ Line 29: / Line 30: @@
 In the light of climate change and the resulting less reliable rainfall, mechanized lift irrigation techniques are becoming increasingly important to meet the demand for a more constant irrigation pattern. These techniques enable higher and more reliable yields. Increased annual yields and diversification of crops reduce risk.

 The GIZ project “Sustainable Management of Natural Resources in Gorno-Badakhshan” in the Pamir region of Tajikistan works together with local craftsmen and has developed three types of pump technologies (swim, ram and treadle pumps). Local craftsmen are trained to produce and to install these pumps. A retail cooperative was founded, with support of the [http://www.naturalresources-centralasia.org/index.php?id=45 GIZ project],[[File:Ram Pumps, GIZ Tajikistan 2010.jpg|thumb|right|184px|File:Ram_Pumps,_GIZ_Tajikistan_2010.jpg|alt=File:Ram_Pumps,_GIZ_Tajikistan_2010.jpg]]

 to produce quality materials to be used in the production of the pumps. This cooperative promotes the metal and wood productions of local craftsmen by up-scaling the value chain of water efficient technologies, i.e. pumps. Green products, such as energy efficient pump technologies, add a new dimension to the increasing importance of the value chain debate. Once local craftsmen are have mastered the production of the pumps, they sell them via existing market mechanisms and generate income.
