Problem

Inland valleys can be good locations for irrigation, however waterlogging can make it difficult to grow vegetables. These valleys are often used for rice farming only.

}

Solution

This innovation makes it possible to grow vegetables in seasonally waterlogged valleys throughout the year by using a system combining features that assist in both irrigation and drainage.

Target Beneficiaries

Smallholder Farmers

Mission and Vision

To allow areas for rice irrigation to be used for vegetable irrigation.

Innovation Description

This is a system that builds raised beds running cross slope, separated by drainage canals. It uses two levels of raised bed to create more drainage and aeration in the root system. This has been most successful with crops including onions and leafy greens. Two larger canals are constructed on both sides of the plot to be irrigated, running down slope. If the field is wide, a series of these canals can be made. These canals can be used to bring irrigation water into the field during the dry season, and are used to drain excess water during rainy season or irrigation. Smaller canals are dug across the slope, connecting to both the canals. Land should be leveled as well as possible between the two canals across the slope, to allow water to fill and drain freely. Once the canals are dug, the land between them should be plowed and raised up to as high a level from the canal bottom as possible. This raised bed is then leveled, and furrows are made running perpendicular to the upslope and downslope canals. These furrows are closed, and do not enter the downslope canal. A small canal runs parallel to the upslope canal to fill the individual furrows. Water is blocked from the upslope canal to allow water into the raised bed.
