ECOSYSTEM
“A dynamic complex of plant, animal, and
microorganism communities and the nonliving
environment interacting as a functional unit” of which
humans are an integral part (MA, 2005a).

ECOSYSTEM SERVICES
Ecosystem services are the benefits (goods and
services) that are derived from ecosystem functions
which contribute to human well-being directly or
indirectly (Costanza et al, 1997; Daily, 1997; de Groot
et al, 2002; MA, 2005b; TEEB, 2010a).

RESEARCH BACKGROUND
The development process of the Bangladesh delta has
gained momentum.
In its path of progression it faces multi-dimensional
challenges related to, among others, population
growth, rapid urbanization, land use change and
natural hazards compounded with likely climate
change.
Social, economic and environmental aspects,
especially in urban areas, are under pressure.
Dhaka, the capital city of Bangladesh, is the hub of
socio-economic and cultural activities of the country.
As this city is growing, managing its ecosystem
services is becoming increasingly complex.
