Desert control methods in Iran

Stabilizing the shifting sand dunes Methods in Iran are:

•Biochemical method
•Biomechanical method
•Biological method



•Biochemical method
In this method, the first spraying the petroleum is used for stabilizing the shifting sand dunes by the tanks that are equipped with strong pumps,

•For seeding, Before spraying petroleum mulch we should seed near to raining season and then create a suitable cover on seeds.
•For seedling, we can do planting before and after spraying mulch. The selective trees should be compatible with ecological conditions.


Characteristics of petroleum mulch:

1) For the agriculture production should be harmless.2) Don’t injure hygienic the persons that spray petroleum mulch.3) Don’t remain unfavorable effects during ploughing and mixing the mulch and soil.4) Don’t have the unfavorable smell.5) Prevent from cracking the land and accelerate the sprouting.6) The air and rain can penetrate into it.





Biomechanical method

In this method, With creation of wind breaks on sand dunes and planting of seedling, prevent from shifting sand dunes and theirs detriments

Biological Method

In this method, The plants for plantation of seedlings are produced in stations of shifting sand dunes stabilization. These trees are sowed in mentioned regions in winter or at first are grown in plastic vases and then are transferred to original lands. Seeding is one of actions for stabilizing the shifting sand dunes. Yearly a lots of seed are gathered from artificial forests in desert .They are showed in another areas, suit helps to develop the vegetation covers in another regions.

Combating desertification objectives

•Protection of environment

•Stabilization of shifting sand dunes
•Protection and rehabilitation of farm lands
•Conservation of water resources
•Protection of roads and communication networks
•Sustainable reclamation of human settlements
