Dug Well in Chareimara

Dug-Out Well (印度)

Chahala

描述

It can be defined as combination of structural & agronomic measures where along with other technology like Water harvesting structures & field bunding on the upper reaches & a dug out well is constructed in the periphery of the drainage line which is a govt land. The 15 acres of land near to its sphere of influence which reamained fallow earlier could yield good production system throughout the year.It is in the semi-arid climatic zone with moderate slope in medium soil depth conditions. The whole idea is to avail water & link with self-subsistance & market oriented production systems from private lands.

The area is located at the foot-slopes on the major drainage line of the watershed. The technology area is located near the main drainage line, therefore, the sub-surface water availability is more & can be utilised for cultivation of crop even in dry spell of the year. Earlier the farmers near to this place tried to dig a small well & could irrigate for only 2-3 months of the year to get some subsistence crops. Therefore, water availability throughout the year is a first priority of the farmers. At the outset, a livelihood focused micro-plan had been prepared by the villagers stating the details of the base-line data along with problems & alternative solutions. The patch was identified to be the worst affected & the owners of the land are poor people (defined by villagers). Usually the land users used to migrate in search of labour due to loss in the agriculture. It is because the water availability is not there at the time of requirement. The people of this patch are ready to contribute at least 10% of the cost as the structure is to be constructed in government land. In the mean time the project sent the PIA to Water technology centre for eastern region, Bhubneswar to study the linking of water harvesting structure & dug-out well & its relevance in this context of our situation. The technology was done in the village Chareimara which is one out of 3 villages of one watershed, located at the lower reach of the watershed. In the meantime many water harvesting structures & field bunds were constructed due to which the water could be stored in the recharge zone. This area is again a mix of stony patches in the crop land. One water harvesting structure was constructed just at the upper reaches. The surrounding area was totally unbunded with clay loam soil. Therefore, land users are of opinion to go for a deeper dug well which can feed water through out to at least 15 acre of land. The requirement of land users was to get some water in each farmers land to protect the Kharif & rabi crop including summer vegetables. A four-day in field training was conducted by the project to community link workers (SWC), particularly on patch treatment, use of levelling instruments like A-frame, proper planning, design, lay-out of different type of structure in a map & ground. At the same time there was a blind belief that large water harvesting structures are more useful to farmers. So the land users demanded for a large WHS on the drainage bed which requires huge investment & high maintenance cost. But when some farmers of that watershed could get good result by digging well these land users also started thinking about a "community dug-well". After many rounds of discussion with the land users by the SWC specialist followed by a detail transact along with land users, the results of first round transact was mentioned in the micro-plan. But the aim behind subsequent transact was to looking at problems & demarcating on the map. After that estimate was prepared & lay-out of the well was done by SWC specialist with the help of community link workers & land users. The lay-out is also little bit different from traditional well i.e. square shaped in stead of round shape. The work was implemented by the land users & 7 outside labourers with the supervision of the User's group leader & monitoring was done by the SWC specialist. The priority by the land users was agronomic measures like changing the crop in the land. Training was conducted on the probable alternatives of agronomic measures like taking of crop which is of little longer duration, intercrops & cash crops etc. The structural measures are subsidised by the project & the agronomic measures was taken up on loan basis. The development fund was also generated out of contribution from the land users which was deposited in a separate account for future maintenance cost.

结论和吸取的教训

长处: 土地使用者的观点
  • Water availilbilty
  • A vibrant community institution could be strngthed.
  • A well is much better than a large water harvesting structure, it became a eye opener in the surrounding villages.
长处: 编制者或其他关键资源人员的观点
  • Water availability in the dry spell

    How can they be sustained / enhanced? Integrated & threes season land use practice
  • The water availability will be there through out the year.Therefore, 15 acres of land can be irrigated & three seasonal crop can be taken up.
