Definition of drought and climate services for water supply management

Summary

This report defines drought as a complex and temporary condition related to reduced water availability and highlights its multidisciplinary nature and link to the hydrological cycle. It presents climate services as the use of climate data, information, and knowledge to support decision-making, and outlines monitoring approaches and drought indices (SPI, SPEI, PPN) to identify the duration and intensity of drought events.

It further describes the challenges faced by small producers in accessing water during drought conditions, including limitations in storage, distribution, and operational coordination.

The report presents possible support actions such as drilled wells, water storage systems, and strengthening municipal resources, supported by practical experiences from implemented projects that demonstrate both outcomes and limitations in water supply management.
