dessecació

Dessecació is a process of drying out or becoming dry. It refers to the removal of water or moisture from a substance or organism. This can occur naturally through evaporation or be an induced process for various purposes. In biology, desiccation can be a natural phenomenon for some organisms, like certain plants or invertebrates, allowing them to survive in arid environments. For humans, desiccation can lead to dehydration, a dangerous condition characterized by insufficient body water.

In agriculture, desiccation is often a deliberate process. Farmers may use desiccation to dry crops before harvest, making them easier to process or store. This can involve natural drying under the sun or the use of chemical desiccants. In a broader sense, desiccation can refer to the drying out of landscapes, such as in drought conditions, which can have significant ecological and economic impacts. The term is also used in preservation techniques, where removing moisture inhibits the growth of microorganisms and preserves materials. The rate and extent of desiccation depend on factors like temperature, humidity, air movement, and the properties of the substance being dried.
