2.1 Short description of the Technology

Definition of the Technology:

"Bo Bao Kanomkrok" is a storage pond excavated as a source of water for agricultural purposes. It is shaped in the form of a rectangle to store water in the rainy season and thus to be a source of water in the dry season.

2.2 Detailed description of the Technology

Description:

A water storage facility or "Bo Bao Kanomkrok" is a pond excavated as a source of water for agricultural purposes in the dry season. It is dug in a form of rectangle to store water during the rains and thus to prevent water from drying up in the area. It increases agricultural activities in the dry season. Bo Bao Kanomkrok is excavated in a farmer's agricultural land to a dimension of 8 meters wide, 8 meters long and 10 meters deep. It has a capacity of 640 m3 which is appropriate for an agricultural area of about 6 rai. Water in the storage "bank" is available through the dry season. To establish it, the pond is dug vertically with no side-slopes. After the pond is completed, muddy soil is coated around the bottom and sides to prevent water from seeping out. Plants are grown around the edge of the pond to prevent collapse. Therefore, Bo Bao Kanomkrok is an appropriate low cost option for providing stored water to crops on a small-scale. It is a good prototype for extending to other agricultural plots in the community and adjacent communities. In the small-scale agricultural areas there are fruit-bearing trees, perennial crops and vegetables such as sweet yellow marian plums, durians, santols, hairy-leafed apitongs, Barking Deer's Mango, hedge bamboo, Paco fern, bananas, Garcinia cowa, Brazilian Pepper-tree, etc. Bo Bao Kanomkrok must be maintained by the owner so that it will be efficient in storing water throughout the year.

Ban Thung Krapong Learning Center, Nakhon Nayok province is the prototype for communities to learning to solve problems by themselves, by studying from nature and the environment in the community.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view	How can they be overcome?
The ponds must be maintained by the owner so it will be efficiency in storing water throughout the year.
Choosing the area to drill requires certain experiences/expertise, as the area must have a spring.

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Because the sediment deposits in the pond with time, it may affect the amount of stored water.	The sediment should be excavated out of the pond every year or as needed.
