Soil moisture

Soil moisture Groundwater is an important source of water for consumption and irrigation in many parts of the world. We can estimate the amount of water by comparing precipitation and evaporation . We can also detect how wet the top layer of the soil is using satellites looking at the top few centimetres of soil. A map of soil moisture can be useful to see where there is risk of drought or where certain crops can be grown. What can we do to preserve water in areas where there is very little groundwater ?
