5. What is
NRM?

6.  GIS (Geographical Information System) is mainly used for mapping processes.
GIS is a computer-based information system that is aimed at collecting, storing,
manipulating, analyzing, organizing, managing, summarizing and displaying all
types of geographical data.
 GIS has a wide range of application. It is equally important in natural resource
management. The GIS in Natural Resource Management is a resourceful
technique in measuring the natural resource assets.
 The GIS in Natural resource Management identifies the human impacts on
natural resource and support for the utilization of natural resources. Firstly the
data are collected from the land cover, vegetation, soil and geology which are
the parts of natural resources and then they are mapped using GIS technology.
These data are collected using remote sense technique through aerial
photographs or satellite image for study.

8. • The major application of GIS in natural resource management is in
confronting with environmental issues like a flood, landslide, soil
erosions, drought, earthquake etc.
• GIS in natural resource management also address the current
problems of climate change, habitat loss, population growth,
pollution etc. The solution to these problems is the application of
GIS in natural resource management.
• Yes, introduction to GIS has solved many problems related to the
natural environment. GIS is a powerful tool that is used in the
management of natural resources. Some applications of GIS in
major fields are discussed on upcoming topics

Risk Management

10. • GIS in natural resource management is used in the reduction of a
natural hazard such as flood, landslide, soil erosion, forest fires,
earthquake, drought etc.
• One cannot totally stop these natural disasters but can minimize
these warnings by early planning, preparation, and strategies.
GIS in natural resource management is being used in analyzing,
organizing, managing and monitoring the natural hazards.
• GIS in natural resource management provides a spatial data of
the disasters that have taken place before or might to occur so
that early risk can be prevented. It is indicated through GIS-based
map.

13. Oh you safe! Hope the fire won't given you
any wound...
Those NIST cameras may provide you
some good visuals but you can't expect the
same thing in every part of the globe..
For analyzing purposes you need accurate
data rather than visuals.. That's where GIS
gets uprooted

took from the sky of a place before and after a
forest fire

14. BEFORE AFTER

15. What happened in the 2011 Japan tsunami?
The Tohoku earthquake caused a tsunami. A tsunami—Japanese for “harbor wave”—is a series of powerful
waves caused by the displacement of a large body of water. ... The Tohoku tsunami produced waves up to 40
meters (132 feet) high, More than 450,000 people became homeless as a result of the tsunami.

17. This map snap will bring a base plan on identifying the upcoming or
past tsunami's ,holds a record of them and creates a map as now we
are looking.. So GIS an indeed application isn't it?

detection

19. • GIS in natural resource management provides information
about land area change between time periods.
• The land change documents detected through satellite
imagery or aerial photographs.
• It is a useful application in land change, deforestation
assessment, urbanization, habitat fragmentation etc.
• The information obtained from GIS in natural resource
management help to study the specific area
and monitoring can be done in and around the area.
• It is a way of studying the variations taking place
in landscape and managing the environment.

detection

22. o RUSLE(Revised Universal Soil Loss Equation) used to estimate soil loss in a coastal river
basin.
o Remote sensing data helped in land use-land cover classification.
o GIS helped to integrate, analyse and map potential soil erosion zones.
o RUSLE model utilizing remote sensing and GIS useful for soil erosion probability prediction.

25. •Natural resource inventory is a statistical survey of
the condition of natural resources.
•It provides relevant information about the
environment condition and policy including
conservation program that is obtained through GIS
in natural resource management.
•The information through maps in GIS provides the
information of location and current resources.

monitoring

8.Gunaselvam

27. •GIS in natural resource management provides a graphical
data that helps in monitoring the environment.
•It determines the qualitative and quantitative data about the
environment issues such as pollution, land degradation, soil
erosions etc.
•GIS in natural resource management detects these
problems and predicts the future hazards.
•Thus, GIS in natural resource management monitors all
these environment problems.

30. •• GIS helps in the management of land providing resourceful data in
doing construction works or any agricultural works. It selects a
suitable site before any change is done.
•• GIS in natural resource management is conserving wide range of
biodiversity by the pre information obtained through it. Many
biological habitats are protected and further planning for the
protection of flora and fauna is promoted.
•• GIS in natural resource management provides hydrological data for
the analysis of watershed management and Watershed analysis.
•• GIS in water resource management is now extended in the use of
mineral exploration in various developed countries like USA, Canada
and Australia.

33. How a geographic information system (GIS) can be used in risk analysis?
It focuses on liquid hazardous waste transport and utilizes records archived by the London
Waste Regulatory Authority.
This data source provides information on the origin and destination of each waste stream, but
not the route followed during transport. A GIS was therefore employed to predict the paths
used, taking into account different routing criteria and characteristics of the available road
network.
Details were also assembled on population distribution and ground-water vulnerability, thus
providing a basis for evaluating the potential consequences of a waste spillage during
transport.
Four routing scenarios were implemented to identify sections of road which consistently saw
heavy traffic. These simulations also highlighted that some interventions could lead to risk
tradeoffs rather than hazard mitigation.
Many parts of the research would not have been possible without a GIS, and the study
demonstrates the considerable potential of such software in environmental risk assessment
and management.
