Drought, a global concern
Drought is characterized by a period marked by a significant lack of water in a given area. This phenomenon has an impact on vegetation, which then shows notable signs of water stress. As a consequence, drought impacts all plant, animal and human life. It is defined by the UNCCD as “a naturally occurring phenomenon that exists when precipitation has been significantly below normal recorded levels, causing serious hydrological imbalances that adversely affect land resource production systems”.
