Ecosystems
, IPAT Equation Impact = Population x
Affluence x Technology
Population has a direct
relationship with impact Technology: can either
degrade or improve
Affluence: environment
measured using
GDP, does not have
a simple
relationship to
impact
GDP: value of goods and
services produced in a year
, ECOSYSTEMS
• Definitions and examples
• Natural capital and ecosystem services (provisioning
services, regulating services, cultural services)
• Matter and energy: Transport in ecosystems
• Role of biogeochemical cycles
• Globalization and sustainable development
Indian Institute of Technology, Kharagpur
, Ecosystem
• It is a community or
group of living organisms
that live in and interact
with each other in a
specific environment.
• Also called as
Holocoenosis
