Pressure – State – Impact – Response (PSIR) Framework
This section includes the spatial analysis of green, blue and brown environment
issues. Selected environment themes are analysed under the PSIR framework. The PSIR
analysis is shown as Pressure – State – Impact - Response map.
The information comes
primarily from Ministry of Statistics and Programme Implementation, Environment
Atlas of India (CPCB), National Health Profile, Forest Survey of India etc. The
specific details for the thematic issue are depicted on the interactive map
page under the head about the map.
The issues analysed
under PSIR is as follows:
- ▪ Land Degradation
- ▪
Biodiversity Loss
- ▪ Forest
- ▪
Water Scarcity
- ▪
Degrading Water
Quality
- ▪
Air Pollution
- ▪
Mining
- ▪
Municipal Solid
Waste
The PSIR framework provides
a systematic categorization of socio-economic, environmental and natural resource
information under four headings: Pressure (stresses or agents of environmental change),
State (resources assets, environmental quality), and Societal Response. Human activities
exert pressure on the environment causing the state (condition) of the environment
to change. Society, at different levels, will then respond to this change with policies
that affect human activities and directly affect the state of the environment as
well.
Status of the issue
This part summarises the condition or quality of the environment and trends
in that condition brought about by human or other pressures.
One such example is water quality levels. This corresponds to ‘S’ (State) in the
PSIR framework.
Cause of the problem
The more specific economic,
social, institutional or other pressures on the environment that may contribute
to or cause particular environmental states and impacts of concern.
This part Corresponds to ‘P’ (Pressure) of the PSIR framework.
Impact of the issue
This part summarises information about the secondary effects of the issue on people,
environment and economy, e.g. poor health or economic damage due to bad drinking
water. This part corresponds to the ‘I’ (Impact) of the PSIR framework.
Response to the issue
In this part measures taken by different stakeholders to improve the situation are
described, e.g. water quality monitoring programme. This part corresponds to the
‘R’ (Response) of the PSIR framework.
