12. Socio-Economic Trends
in the delta plain
• Growing populations;
• Rising wealth and improving health, but questions
of inequality;
• Changing livelihoods and migration;
• Urbanisation and infrastructure expansion;
• Intensification of agriculture;
• Increasing demand for flood management;
• Increased water demand.

13. Research Questions
• To understand the present relationship between ecosystem
services and human well-being and health in the
Bangladeshi portion of the Ganges-Brahmaputra delta.
• To develop participatory methods to predict how these
ecosystem services might evolve over the coming years and
decades (up to 50 years) and their influence on human well-
being and health under the multiple drivers of change in
operation.
• To analyse how policy can influence these outcomes and
promote ecosystem services and human well-being and
health.
• To develop participatory methods to select robust policies
that are effective across the range of uncertainty, including
adaptive management approaches.
• To test the transferability of these methods to other
populated deltas.

15. Systems Dynamics: Integration of Socio-Environmental Models
in such a way as to consider the systems impacts of
interventions and policies on socio-economic
as well as biophysical outcomes

conceptualisation Systems are combined
for ESPA Deltas to produce an integrated
Socio-environmental approach
with feedback and thresholds
