Over the years, unchecked soil erosion can lead to the formation of deeper and deeper gullies. There are several methods for controlling gully erosion, which can be chosen depending on the materials available.

If it is a small gully, vegetation can be planted in strips across the gully to slow the velocity of water, trap silt, and prevent further erosion.

These techniques are useful to slow runoff and erosion from sloping land, and also to revegetate degraded areas. Areas with high rainfall, steep slopes, and thin soils should use slightly graded bunds / terraces / trenches to allow some drainage.

Bunds have many benefits, including marking the boundaries of farm-holdings, slowing the movement of soil and water, and providing a place for integrating trees into agricultural systems. Here are some tips for using bunds within farmland:

• Cattle should be kept away from the area while establishing saplings, by using livehedge fencing. Cactus, Euphorbia spp, and Agave are useful for a livehedge fence.
• Larger trees can be planted on boundary bunds, and smaller trees which will be harvested more frequently can be planted on internal bunds, which divide one holding into separate sections.

In places where the land is too degraded for agriculture and the soil is too shallow for bunding, rocks can be used to protect existing stumps from browsing and allow regeneration. Rock fences can also be used to protect areas planted with fodder species. Hardy, drought tolerant trees such as neem, tamarind, custard apple, acacia, and eucalyptus can be planted.

It is similar to drip irrigation, but less expensive to install. The pitchers are the round earthen containers used in rural areas for water storage, ranging from 10 to 20 liters in capacity. This kind of irrigation is ideal for spreading plants such as gourd, pumpkin, and melon because few pitchers are needed per unit area. It is also very good irrigation for saplings, promoting deep root growth.

Overview

Rainwater is amongst the purest water one can get distilled as it is by the sun. However, in a rainwater harvesting system, the water comes in contact with several surfaces, such as the roof or gutters. Its flow becomes possibly mixed with leaves or dust.
