Dug-out sunken pond cum countour bund (India)

Buda Gata with Adibandha

Description

It can be defined as combination of structural & vegetative measures where contour bunds are constructed from the excavated sandy loam soil of cultivated wastelands in semi-arid climatic(?) zone with moderate slope in medium soil depth conditions in order to link with self-subsistance & market oriented production systems from private lands.

The area is located at the foot-slopes & hill slopes area where run-off is at peaks very often at the time of rainy season. Therefore, sand casting came as a first order priorities by the farmers of this patch. 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, concentraton of poor people (defined by villagers), people of this patch ready to contibute at least 20% of the cost. In the mean time project sent the PIA to BAIF, Bangalore to study the linking of farm ponds & its relevance in this context of our situation. As a demonstration, PIA & other technical team facilitated the villagers. One water harvesting structure was constructed by line deptt of soil conservation just at the down hills to harvest rain water & protect the lands below from sand casting. But there were no alternatives for the land users of that patch about the optimum utilisation recharged water. The surrounding area was totally unbunded with sandy loam soil. Therefore, land users are of opinion to go fo field bunding. Earlier the practice was to dig a trench at upper gadient & put a bund below it out of the excavated soil from trench. But the requirement of land users was to get some water in each farmers land to protect the Kharif & some early rabi crop.(june-dec). By which the lands where, farmers take up only minor millets for their subsistance, that too less production & land So the main purpose of this technology was to convert the land into bunded lands along with to fetch some water at the time of dry spell in between the monsoon period. A four days 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. After many rounds of discussion with the land users, one of them ( rich farmers with more land) was ready to do it in his own land. But, the SWC specialist did a detail transact along with land users, although results of first round tansact was mentioned in the micro-plan. The main pupose was to looking at problems & demarkating on the map. After that estimate was prepared & lay-out of key contour was done by SWC specialist with the help of community link workers & land users. The work was implemented by by the labourers with the supervision of the respective User's group leade & monitoring was done by the SWC specialist. The prioty ranking by the land users vegetaive measures like vertiver & Sabai (grass plantation on the bund along the side of the bund. For that, the necessary requirement like nursery, seedling collection was done by agriculture specialist. 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 vegetaive & structructural 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 maintainance cost.

Establishment and maintenance: activities, inputs and costs

Calculation of inputs and costs
  • Costs are calculated:
  • Currency used for cost calculation: Rupee
  • Exchange rate (to USD): 1 USD = 50.0 Rupee
  • Average wage cost of hired labour per day: n.a
Most important factors affecting the costs
Soil depth is very less, hard soil with slope variation because of undulating lands. The labour was also not sufficiently available at the time of establishment, because the work was implemented at time of main growing season. At that time land users are busy in their own field because of cultivation work.

Conclusions and lessons learnt

Strengths: land user's view
  • Maintainance is very less

    How can they be sustained / enhanced? Only timely care is needed.
  • Land users can have water in their field other than rain water to be used for different purpose.

    How can they be sustained / enhanced? Some demos agriculture was done in this patch which has to be repeated for the second year for confidence building of the land users.
Strengths: compiler’s or other key resource person’s view
  • Water availability in the dry spell

    How can they be sustained / enhanced? If the land users will desilt the pond timely & care to plants grass on the bund.
  • The land where only one crop is possible, vegetable & pulse crop can be taken up as second crop

    How can they be sustained / enhanced? Some methodology is to be applied to keep water in the pond for longer duration.
Weaknesses/ disadvantages/ risks: land user's viewhow to overcome
  • Ploughing operation will be difficult. This is although difficult but th benefit is more, therefore land users will compromise with this type of difficulty.
  • Water availability in dry period & desiltaion process. This can be overcomed by planting vertiver on the sides of the pond & low cost polythene can be used for prolonging percolation rate of water in sandy loam soil.
Weaknesses/ disadvantages/ risks: compiler’s or other key resource person’s viewhow to overcome
  • The farmers started taking up cotton & paddy in stead of minor millets Improved variety of minor millets is supplied to farmers for better yield in comparison to country variety.
  • Diversion of surplus water The land users have to dig atleast one more feet & earthen pipes will be used for the diversion of surplus water.
