Research project: An assessment of the ecosystem service and livelihood implications of government development proposals in coastal Bangladesh - Dormant

Currently Active: 
No

We demonstrate the potential of Integrated Assessment Models (IAMs) to inform strategic policy decision making at the regional level, helping to understand key trade-offs and secondary impacts. We document the Delta Dynamic Emulator Model (ΔDIEM), co-produced with stakeholders, to integrate ecosystem services and household wellbeing, being utilised by the Planning Commission of the Government of Bangladesh for its strategic long-term risk planning.

Funding source: Natural Environment Research Council

Awarded amount: £100,042

Start date: 26/04/2017

End date: 31/03/2018

Reports results from analysis of thre proposed interventions on behalf of the Government of Bangladesh, General Economic Division (GED) using ΔDIEM. GED has responsibility for the strategic development of the delta coastline within Bangladesh and recently enacted the first draft of the Bangladesh Delta Plan 2100 (BDP2100). The BDP2100 contains multiple possible interventions, the majority of which are only in the very early stages of development. This work is assisting in prioritising and refining these proposals. The intervention we investigated included i) A proposed extensive polder network in the south-central region of the ii) A new mangrove green belt iii) Development of a coastal defence wall. We highlight insights on the potential implications for biophysical change and the potential associated poverty and inequality, and on risk transfer between regions and populations. In doing so we demonstrate IAMs growing potential to ask and explore key questions and scenarios about the functioning of integrated biophysical and socioeconomic systems, but also highlight some of their key weaknesses.
