1.4 Déclaration sur la durabilité de la Technologie décrite

Est-ce que la Technologie décrite ici pose problème par rapport à la dégradation des terres, de telle sorte qu'elle ne peut pas être déclarée comme étant une technologie de gestion durable des terres?

Non

Commentaires:

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 Courte description de la Technologie

Définition de la Technologie:

Natural water source in hill top is collected in a small reservoir-chamber ( to preserve natural source), then passes onto a Reservoir Tank (RVT) for drinking water (ferro-cement tank/ Ghaito) with a capacity of 9000L that falls within individual’s plot of land. When the ferro-cement tank gets filled, water overflows, is collected in another reservoir pond (30,000L) for irrigation and other multiple uses. From the Ghaito and reservoir pond, two pipelines are fed and water is supplied into individual Multiple Use Water System (MUWS) tap towers.

2.2 Description détaillée de la Technologie

Description:

The technology is applied in a natural environment. The place of study falls under the dry belt of Nepal, receiving less than average annual rainfall (in context of Nepal). The source of water is natural that is located within a community forest area (samudayik ban), which is owned by the government and consists of trees like Sal, Supari (areca nuts), etc. From there, water collects onto a Ghaito / ferro-cement tank, which falls on the land owned by Mr. Krishna Bahadur B.K., who voluntarily agreed to donate the land for its construction. The total area covered for the tank is 1 ropani (1 hectare = 19.65 ropanis). From the reservoir, water is collected in a ferrocement tank / Ghaito / Thulo tanki (for drinking water) and a reservoir pond (for irrigation). Poly Vinyl Chloride (PVC) pipes are fed onto the tanks to distribute the water for multiple purposes in 6 Multiple Use Water System (MUWS) tap-towers; which 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 purposes to the community that is comprised of 23 households, through a cheap, effective and simple system. For establishing the system, labour and construction materials were needed for building Ghaito and pipeline systems. For the maintenance, manual labour is necessary. The natural source of water is locally maintained. The quality of the water that is supplied to the 23 households is good and the quantity seems sufficient for the number of households. Operation and maintenance works are done by the locals who collect NPR. 50 from each household. The system is guarded by a watchman (Chaukidar) who is given a monthly stipend of NPR. 800 from the committee. 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, primary survey of the natural source of water was done by another NGO- Anukulan Project with the help from UK-AID (NPR. 1,46,000) , and the remaining funds were contributed by the locals’ group (NPR. 1,39,183), by collecting NPR. 3000 initially then NPR. 1200 from each household. The then Village Development Committee (VDC) donated NPR. 1,00,000 and labour costs borne by the locals amounted to NPR. 85,600. Total amount invested for the project amounted to NPR. 4,70,783. Benefits of the technology are the sustainable use of water resources through a MUWS system, cheap and effective way to conserve water resources and the ensured availability of clean water even through dry seasons. The villagers like the facts that the water is clean, more water is available for irrigation for vegetable farming, and that their day-to-day life is simplified. They dislike the limited availability of water during dry season and that out of 6 systems only 3 are in operation and the other ones are in a non-working condition.
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. Amrita B.K.. The committee conducts a monthly meeting on 10th of each Nepalese month 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 contributes NPR 50, 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 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 2073 B.S. ( 3 years) . Equal number of male and female members are in the committee dedicated to the MUWS system.

3.2 Type(s) actuel(s) d'utilisation des terres, là où la Technologie est appliquée

Commentaires:

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 Est-ce que l’utilisation des terres a changé en raison de la mise en œuvre de la Technologie ?

Est-ce que l’utilisation des terres a changé en raison de la mise en œuvre de la Technologie ?

• Oui (Veuillez remplir les questions ci-après au regard de l’utilisation des terres avant la mise en œuvre de la Technologie)

Commentaires:

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.
After the technology, vegetables from green houses in their backyards are sold to markets, which has acted as an alternative source of earning perennially.

3.4 Approvisionnement en eau

autre (par ex., post-inondation):

• Natural source (Mool) of water in foliage atop a hill that falls under Mr. Krishna Bdr. B.K.'s land

Commentaires:

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 ferro-cement tank for drinking purposes ( 'Ghaito' in local language) and the reservoir pond for irrigation purposes.

3.5 Groupe de GDT auquel appartient la Technologie

• récupération/ collecte de l'eau
• gestion de l'irrigation (incl. l'approvisionnement en eau, le drainage)

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

3.6 Mesures de GDT constituant la Technologie

Commentaires:

The technology is comprised of structures like Tanks (ferro-cement), Ponds (Concrete), Pipes, etc which use a myriad of resources like cement, iron rods, PVC pipes, fences for enclosure, etc.

3.7 Principaux types de dégradation des terres traités par la Technologie

Commentaires:

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 Prévention, réduction de la dégradation ou réhabilitation des terres dégradées

Spécifiez l'objectif de la Technologie au regard de la dégradation des terres:

• prévenir la dégradation des terres

Commentaires:

The technology prevents water source degradation, improves perennial water availability, reduces effects like drought, floods, etc. Thus, land degradation by means of lands turning barren, dry,etc is tackled by this technology.
