Aridification is the process of a region becoming increasingly dry
Arid
A region is said to be arid when it is characterized by a severe lack of available water, to the extent of hindering or even preventing the growth and development of plant and animal life...

. It refers to long term change rather than seasonal variation.

It is often measured as the reduction of average soil moisture content.
It can be caused by natural or anthropogenic means such as climate change
Climate change
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average...

, reduced precipitation, increased evaporation, lowering of water tables or changes in ground cover.
Its major consequences include reduced agricultural production, soil degradation, ecosystem changes and decreased water catchment runoff.
