This report is divided in four main topics. The first presents a general analysis of links between the hydrological cycle and climate change, followed by the hydrological cycle in the Caribbean and its impact on water resources. It continues with an analysis of the possible impacts on groundwater due to sea-level rise and several aspects related to water management and finishes with different adaptation and mitigation options that should be implemented in each country's policies.

Hydrological zoning (or simply zoning) is an approach to divide land into different zones based on their hydrological properties. Typically, each type of zone has different land use and development regulations linked to it. This land and water management method aims to protect local water sources from risks of over-abstraction, land salinization, groundwater pollution and waterlogging by managing land use activities based on the assigned hydrological zones.  For example, zones with a high groundwater table, large amounts of surface water (e.g.
