Tools for drought monitoring and control: a meta-analysis in context

The research consisted of performing a meta-analysis of drought monitoring and control tools in all their manifestations, which identified the existence of little consolidated data on hydraulic as a weakness. A total of 3,116 articles published in the period 2000-2020 were analyzed, identifying drought management as the most published topic. Other metrics were worked on, referring to the total number of articles and their distribution by year and country, the distribution by topics and by most cited journals, articles and authors. A total of 46 indices were found to be among the most widely used for drought monitoring and control at the global level, with those applied to meteorological drought standing out among them. No reference was found of indices applied to the management of hydraulic drought, which constitutes a challenge for researchers and managers of water resources.
