Project Overview

Key Delta Characteristics• Complex systems with large vulnerable populations• Multiple drivers at multiple scales• Rapid resultant change, including significant migration• (Lack of political representation – not an automatic focus for policy)• Climate change needs to be analysed in this dynamic context, including established

and emerging migration• As climate change and sea-level rise increases, so the range of sustainable

adaptation choices diminishes

Project Overview

DECCMA AimsBetter understand in deltas:

1. migration processes, including the role of climate change2. adaptation choices, with a focus on migration.

This will take a participatory and adaptive pathway approach that addresses gender dimensions.

Project Overview

DECCMA OutcomesThe analysis will guide sustainable and equitable development of deltas and will:1. identify gender-differentiated stakeholder-relevant scenarios of

local/regional/delta level vulnerability to climate change;2. identify options for effective climate adaptation by the poorest groups

in deltas; and3. lead to the development of gender-sensitive adaptation funding

proposals in the four deltas.
