What have we learned about migration and adaptation in deltas? Last week nearly 50 members of the DECCMA team from Bangladesh, Ghana, India and the northern team convened in Dhaka for the 8th whole consortium meeting. It was an exciting opportunity to learn about a critical mass of research findings that have been developed over the past 3.5 years, and plan how to ensure they inform theory, policy and practice.
When it commenced in 2014, DECCMA set itself seven ambitious objectives, namely:
(1) to understand the governance mechanisms that promote or hinder migration of men and women in deltas;
(2) to identify climate change impact hotspots in deltas where vulnerability will grow and adaptation will be needed;
(3) to understand the conditions that promote migration and its outcomes, as well as gender-specific adaptation options for trapped populations, via surveys;
(4) to understand how climate-change-driven global and national macro-economic processes impact on migration of men and women in deltas;
(5) to produce an integrated systems-based bio-physical and socio-economic model to investigate
potential future gendered migration under climate change;
(6) to conceptualise and evaluate migration within a wide suite of potential adaptation options at both the household and delta level;
(7) to identify feasible and desirable adaptation options and support implementation of stakeholder-led gender-sensitive adaptation policy choices.
During the consortium meeting each country team consolidated its findings around these objectives to synthesise what we have learned so far within each of the deltas. A wide-ranging and detailed set of analyses was presented, from assessment of the existence and status of implementation of adaptation-related policies in each country, to migration patterns and consequences, and models of fishery and livestock productivity. The structure of a hybrid model framework has been developed, based on Bayesian network analysis with multiple nodes so that it can project the impacts of climate change on the biophysical and socio-economic environments, as well as adaptation and migration decisions and consequences.
Planning took place to ensure that these findings are published in the peer-reviewed literature, and also in the form of a book. At the same time, DECCMA is committed to ensuring that research findings are effectively communicated to various stakeholders to ensure that they can inform policy and practice, enabling sustainable adaptation to climate change in deltas and proactive management of projected migration patterns. The integrated assessment model will play a key role in this, and over the course of the project relationships have been built with key stakeholders in each country who have an interest in this information for their planning decisions. Alongside targeted and tailored policy briefs, the team will also be available to support governments in developing adaptation finance proposals.
