1.4 Declaration on sustainability of the described Technology

Is the Technology described here problematic with regard to land degradation, so that it cannot be declared a sustainable land management technology?

No

Comments:

The technology used serves as a source of providing water for drinking and other multiple uses; such that it acts as a means to conserve and manage water resources rather than degrade them.

2.1 Short description of the Technology

Definition of the Technology:

Water from source in hill top is collected in a small reservoir (to preserve natural source), then passes onto a Reservoir Tank (RVT) / Ferro-Cement Tank / "Ghaito" for drinking water with a capacity of 4000L. When the RVT gets filled, water overflows, is collected in another concrete irrigation pond (10,000L) for irrigation. From the ferro-cement tank (Ghaito) and concrete irrigation pond, two pipelines are fed and water supplied into individual tap-system or MUWS tap towers for multiple purposes.

2.2 Detailed description of the Technology

Description:

The technology is applied in a natural environment, i.e. natural water source. The source of water is a natural source of water that sits atop a small hill which is owned by the government. From the source, water is collected in RVT ( for drinking water) and concrete irrigation pond ( for irrigation). PVC pipes are fed onto the tanks to distribute the water for multiple purposes to 4 MUWS tap towers or tap systems or "Thaado". These MUWS tap towers consist of two faucets each- one for drinking and the other for irrigation and other purposes.The major purposes of this technology are to supply clean water for drinking and other multiple purposes through a cheap, effective and simple system. The natural source of water is locally maintained. Operation and maintenance works are not mandatory, however the locals are responsible for maintaining it should the need arise. The system was financed through a public-private-partnership (PPP) program; out of which some amount was funded by a Non-Governmental Organization (NGO)- Sundar Nepal ( NPR. 2,77,000 ), some amount by the Village Development Committee (VDC)- (NPR. 2,63,000), and the remaining amount was collected by a locals’ group (NPR. 60,000). For establishing the system, labor and construction materials were needed for building the tanks and pipeline systems. For the maintenance, manual labor is necessary. The quality of the water that is supplied to the households is good and the quantity seems sufficient for the 19 households. Sustainable use of water resources through a MUWS system, cheap and effective way to conserve water resources, ensuring availability of clean water even through dry seasons are some of the technology's advantages. Similarly, clean water, more water for irrigation for vegetable farming, simplifying day-to-day life are some of the strengths of the technology. Dislikes could be the limited availability of water during the dry season and that out of 4 systems only 2 are in operation and the other ones are in a non-working condition.

Management system in place for MUWS:
A separate committee is set up for the smooth operation of the system, which consists of 20 members- 10 males and 10 females. The head of the committee is Mrs. Kopila Sunar. The committee conducts a monthly meeting to discuss the problems and need of maintenance. During the initial setup, the connection of pipelines from the tap systems to the reservoir tanks was, however, done with the contribution of the locals. Every month, each family from the 19 households contributes NPR. 100 ( One Hundred Rupees) , which goes to a fund that is set up for the times of need. The labor contribution by the people of the VDC was dependent upon the number and availability of family members in the household. Similarly, the use of the MUWS system and water from it is also dependent upon the availability of family members. Little to no maintenance was done to the system till now from 2075 B.S. ( 1 years) . Equal number of male and female members are in the committee dedicated to the MUWS system.

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

Sundar Nepal- a non-governmental organization (NGO) helped with Odaltaal Multiple Use Water Systems

3.1 Main purpose(s) of the Technology

• improve production
• reduce, prevent, restore land degradation
• adapt to climate change/ extremes and its impacts
• create beneficial economic impact

• improve water security and increase efficient use at a household level

3.2 Current land use type(s) where the Technology is applied

Comments:

Irrigation and Multiple Uses: The locals use the technology in order to irrigate their cropland so that the plant productivity is increased. As well, the introduction of this technology has opened up doors to new possibilities like construction of tunnels ( green houses) so that the locals can grow seasonal and off-seasonal vegetables in their backyards. Animal husbandry has also been an increasing practice. Human uses like washing, cooking, cleaning, bathing, etc are amply sufficient due to adequacy of water from this technology.

3.3 Has land use changed due to the implementation of the Technology?

Has land use changed due to the implementation of the Technology?

• Yes (Please fill out the questions below with regard to the land use before implementation of the Technology)

Comments:

Before the introduction of the technology, the land productivity was minimal. Water for human uses like bathing, cleaning, washing, cooking, etc. were scarce; especially during the dry seasons. No green houses were constructed. They used to rear very few cattle.

3.4 Water supply

other (e.g. post-flooding):

• Natural source (Mool) of water in foliage atop a hill

Comments:

The supply of water comes from a natural source ( 'mool' in local language) , where a small enclosure is constructed so that the source is preserved and water is amply supplied to the ferrocement RVT for drinking purposes ( 'Ghaito' in local language) and concrete irrigation pond for irrigation purposes.

3.5 SLM group to which the Technology belongs

• water harvesting
• irrigation management (incl. water supply, drainage)
• ground water management

• Gravity Fed Multiple Use Water System (MUWS) , New Scheme

3.6 SLM measures comprising the Technology

Comments:

The technology is comprised of structural measures, barbed wire fences to surround natural water source, iron lid top, cement enclosure for water source, pipes feeding onto the source, ferro-cement RVT, tap towers, faucets, concrete irrigation pond, etc.

3.7 Main types of land degradation addressed by the Technology

Comments:

Before setting up the technology, much of the water during dry seasons would evaporate from the natural source ( mool) and there would be scarcity of water during dry seasons. This has been addressed by the technology, where securing the natural source of water prevented evaporation and storing water in enclosed tanks helped supply water during dry seasons.
Similarly, due to no preservation of the source and no storage tanks, the water would be soiled by sediments, wastes and insects' larvae. After setting technology up, the quality of water has vastly improved as well.

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:

• prevent land degradation

Comments:

The technology prevents water source degradation, improves perennial water availability, helps tackle with the effects of natural calamities like drought, etc.
