Range management is the process of managing rangelands in arid or semi-arid areas to ensure their long-term productivity.

Irrigation is not typically used in range management because it can lead to increased water use.

Water management is the process of managing water resources in arid or semi-arid areas to ensure their long-term sustainability.

Desalination is not typically used in water management in arid or semi-arid areas because it is a very energy-intensive process.

Awareness raising is the process of educating people about desertification and arid lands.
