Application Of GIS in
Agriculture , Forestry and
Fisheries
GIS In Agriculture
AGRICULTURE
Agriculture Scope
• Crop acreage estimation
• Crop modeling for yield & production
forecast / estimation
• Crop & Orchard monitoring
AGRICULTURE
Benefits
• Timely availability of crop statistics for
decision making & planning
• Crop growth monitoring
• Soil status monitoring
• Regular reports regarding total area under
cultivation
GIS systems are used to
• protect crops,
• solve crop issues,
• damage crop as well as give farmers an easy way
to access information about their crops season by
season.
• what this weather could do to crops,
• could move fields to better geographic locations,
• know how to irrigate based on local water
resources and weather patterns.
Geographic and geologic features of current (and
potential) farmland scientists and farmers can
work together to create more effective and
efficient farming techniques;
• this could increase food production in parts of the world
that are struggling to produce enough for the people
around them.
• GIS can analyze soil data combined with historical
farming practices to determine what are the best crops to
plant, where they should go, and how to maintain soil
nutrition levels to best benefit the plants.
The various types of mapping provided by RS
required by GIS to be useful for agriculture
are:
• soil type mapping
• crop coverage mapping
• rivers/ distributaries mapping
• land use mapping
• contour mapping
• irrigation system mapping
• meteorological mapping
Soil type mapping
• For planning of agriculture on a broad scale it is
extremely important to know different types of
soils, type of crops they can support and areas
having the type of soil. This information if used
effectively can greatly improve the agricultural
output and its quality.
• Some attributes of soils are: humus content,
nutrient content, name etc.
Crop coverage mapping
• Maps indicating crop coverage are very useful in
estimating the yield of various crops. These also help in
analyzing existing methods of agriculture such as crop
rotation, terracing etc. In order to bring forth any
improvements, it is important to study the existing trends
and methodologies.
• Some attributes of crops are: suitable season/ climatic
conditions, water requirements, manure/ fertilizer
requirements, total time for sowing reaping and harvesting
etc.
Rivers/ distributaries mapping
• These maps show the geographical location
of the different river and distributaries
systems in and around an area. Knowing his
is helpful in locating nearest source of water
and designing of most economical canal
systems.
• Attributes: name, volume, depth, width etc
Land use mapping
• These maps give information about how the land
is already being used. It helps in analyzing how
effectively the land resources are being used and
in coming up with more economical suggestions
for the same in addition to keeping updated
records used for various other calculations.
• Attributes: kind of usage, total forest coverage,
total agricultural output of an area, estimated
urbanization of an area etc
Contour mapping
• These maps show the elevation data of the
various geographical features on the earth’s
surface. This information helps us in
estimating important data such as the most
economical laying of canals considering
cost of excavation and leveling etc.
Irrigation system mapping
• This kind of mapping deals with details of
older or existing systems such as dams and
canals. Study of this information helps in
estimating how efficiently the systems work
and on its basis determine the extension
projects and maintenance programs.
• Attributes: length of systems, efficiency
details, areas served, volume of water
carried, benefits etc
Meteorological mapping
• Rainfall patterns, climatic conditions, seasonal
changes and predictions are the areas dealt with
under this kind of mapping. This is important
information required by famers and agriculturists
to plan the type of farming most suitable and
economical. It also helps in estimating how much
water is to be let out into the canal systems in
accordance to the predictions of the rainfall
intensities.
Identification, area estimation
and monitoring:
• identification, estimation of growing stock,
analysis of distribution and monitoring at
regular intervals are major aspects in
plantation crops.
he specializedmanagement practices make the distribution ofplantation crops rather more localized in comparisonto other agricultural crops.The identification, estimat
Crop condition assessment
• The physiological changes that occur in a
plant due to stress may change the spectral
reflectance/ remittance characteristics
resulting in the detection of stress amenable
to remote sensing techniques
• Crop monitoring at regular intervals during
the crop growth cycle is essential to take
appropriate measures and to asses
information on probable loss of production.
Crop yield modeling and
production forecasting:
• The information on production of crops
before the harvest is very vital to the
national food policy planning and economy
of the country.
• Reliable crop yield estimate is one of the
most important components of crop
production forecasting.
Agricultural draught assessment
• Draught assessment is yet another area
where in remote sensing data has been used
at operational level.
• The district level drought assessment and
monitoring
Reflectance modeling
• Physical reflectance models for crops serve the
important purpose of understanding the complex
interaction between solar radiation and plant
canopies.
• In order to obtain a reliable yield prediction,
growth of crops has to be modeled by means of
crop growth models.
• Crop growth models describe the relation between
physiological process in plants and environmental
factors such as solar irradiation, temperature,
water and nutrient availability.
GIS In Forestry
Forestry
Forestry Scope
• Satellite image based forest resource
mapping and updation
• Forest change detection
• Forest resource inventory
• GIS database development
Forestry
Benefits
• Availability of baseline
• Planning for aforestation
• Futuristic resource planning
• Sustainability of environment
• Wild life conservation & development for
information strategies recreation purpose
Biodiversity
• Remote Sensing Technology in biodiversity
measure at landscape level gives a
perspective horizontal view and helps in
delivering different landscape elements and
their spatial characteristics
Biodiversity
• Remote sensing forms a valuable tooling
mapping and monitoring of biodiversity and
provides valuable information to
• quantify spatial patterns,
• Biophysical patterns,
• ecological process that determine species
richness and anthropogenic factors causing
loss of species richness and for predicating
response of species to global changes.
Forest degradation
• The rapid depletion of forests made
inessential to know the rate and trend of this
degradation so that timely measures could
betaken to prevent further loss of forest
resources.
• Timely and accurate information for
detecting changes over a period of time is
required for forest ecosystems
Forest fire
• Through GIS forest fair can also determine
GIS InFisheries
Fisheries
GIS is used for
• defining and mapping Fish Habitat,
• planning and executing living marine resource,
• tracking marine mammals and analyzing their foraging and
migratory patterns,
• mapping and analyzing commercial and recreational
fishing catch and effort,
• evaluating the effectiveness of marine protected areas, and
responding to natural disasters.
Habitat
GIS also facilitates
• the process of defining Essential Fish Habitat
(EFH),
• Habitat Areas of Particular Concern (HAPCs)
Stock Assessment
GIS is used for
• Important information sources for stock
assessments are living marine resource.
• Surveys and biological studies provide data
on species distribution and life history.
Socioeconomic Analysis
GIS is used to
• map trends in business practices
• profile community involvement in fisheries
• analyze recreational fishing site selection
• and most recently, as a tool to monitor and
assess impacts of hurricanes .
