2.1 技术简介

技术定义:

A sunken structure (12 x 12 x 3 m, more suiable), constructed by escavation in arable land with a view of temporary runoff storage tapped for protective irrigation, and to increase percolation for recharge of ground water (to convert surface to subsurface flow)

2.2 技术的详细说明

说明:

A farm pond comprises of excavated portions of 12 x 12 x 3 m with the steps at 0.6m depth each. The excavated earth is deposited all around the structure as a bund, with a burm space of 1m. An inlet cum outlet provided in the course of flow of rain water to collect and dispose the excess runoff.

Purpose of the Technology: (1). For storage of exess runoff. (2) to increase percolation for ground water recharge, (3). To use for protective irrigation during dry period, (4). To stop further deepening of watercourse in arable lands

Establishment / maintenance activities and inputs: Selection of beneficiary is by the community and site selection, Design/ layout and excavation by the project staff with participation of the beneficiary. Desilting of the structure is by the beneficiary

Natural / human environment: surrounding lands are more slopy and with exposed rocks, most of the surrounding area is left for grazing

6.5 技术采用

注释:

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: The community is motivated with the benefits from this SWC structure. Some of them have already deepened the farmponds to increase its storage capacity.However, since most of the farmers are having very small land holdings and there was continous dry season from last three years, even if the farmers are motivated and aware of the technology of farmpond, they could not take up on their own (without financial assistance from the project.

6.7 该技术的优点/长处/机会

土地使用者眼中的长处/优势/机会
Increased storage of water How can they be sustained / enhanced? Desilting by the farmer
Reduce gully formation
Bring more area under irrigation How can they be sustained / enhanced? By giving life saving irrigation
Economic benefits How can they be sustained / enhanced? By yields (monocropping to multiple cropping) --> more income
Recycle the silt is beneficial How can they be sustained / enhanced? Other the silt would been lost every year and it is good to retain the soil fertility.

编制者或其他关键资源人员认为的长处/优势/机会
Storage of water How can they be sustained / enhanced? By deepening
Reduced runoff velocity How can they be sustained / enhanced? By mentainance
Breaching of bunds down stream How can they be sustained / enhanced? By reducing the run-off
Replicability How can they be sustained / enhanced? if a famer has his own labour/ man power then he can go for its construction.
Water harvesting How can they be sustained / enhanced? recycle for protective irrigation during peak season.
