ADVANCED
TECHNOLOGY IN
CONSERVATION OF
ENVIRONMENT.
WHY CONSERVATION IS IMPORTANT?
THE EARTH’S NATURAL RESOURCES INCLUDE AIR,
WATER, SOIL, MINERALS, FUELS, PLANTS AND ANIMALS.
ALL THE THINGS WE NEED TO SURVIVE SUCH AS FOOD,
WATER, AIR AND SHELTER COME FROM THESE
NATURAL RESOURCES.
THESE RESOURCES CAN EITHER BE RENEWABLE OR
NONRENEWABLE.
PEOPLE OFTEN WASTE NATURAL RESOURCES. ANIMALS
ARE OVERHUNTED, FORESTS ARE CLEARED, FERTILE
SOIL IS EXHAUSTED AND LOST TO EROSION, FUEL
SUPPLIES ARE DEPLETED, WATER AND AIR ARE
POLLUTED.
ENVIRONMENTAL CONSERVATION IS AN UMBRELLA
TERM THAT DEFINES ANYTHING WE DO TO PROTECT
OUR PLANET AND CONSERVE IT’S NATURAL
RESOURCES SO THAT EVERY LIVING THING CAN HAVE
AN IMPROVED QUALITY OF LIFE.
CONVENTIONAL METHODS OF
CONSERVATION.
THE THREATS ARE SERIOUS AND ARE MANY; HABITAT
DESTRUCTION, CLIMATE CHANGE ARE TO JUST NAME A
FEW. BUT ADVANCEMENT IS TECHNOLOGY GIVES THE
METHOD OF CONSERVATION AN EDGE.
FROM SATELLITE ENABLED CAMERAS TO ELECTRIC
CARS, TECHNOLOGY CAN HELP US PROTECT THE
FUTURE OF NATURAL WORLD.
Drones
Drones are aircrafts without a human pilot aboard.
They are of various types and used to perform a wide variety of tasks
Delivery Drones
A delivery drone, is an unmanned aerial
vehicle (UAV) utilized
to transport packages, food or other
goods.
Delivery drones are used by e-commerce
sites like Amazon to deliver packages
Military Drones
Military drones carry missiles and are
used for drones strikes. The are usually
under real-time human control with
varying levels of autonomy.
BUT….
They can also be used to save the environment
How exactly ?
Let’s look at how drones
are
saving our environment.
1) PLANTING TREES
Every year, industry, agriculture, urbanisation and mining destroy over 26 billion
trees, according to figures from the American Geophysical Union. This growing
deforestation is associated with pests, hunger and crises, and directly affects
many of man’s resources.
Lauren Fletcher, a NASA engineer, is already replanting forests worldwide with
his drones. The aim is to plant 36,000 seeds per day in difficult-to-reach areas
where traditional methods cannot be applied.
2) PREVENTING FOREST FIRES
1)Forest fires devastate thousands
of hectares of forest every year.
2)To detect such forest fires at an
early stage Technical University of
Madrid (UPM) has designed a system
for automatically detecting forest
fires using drone surveillance, a
system which is catching on
worldwide.
3)According to the Spanish researchers, the system is based on a series
of algorithms which allow detection of the flames and smoke generated by
forest fires, as well as the area affected and wind direction. The algorithms
are highly accurate and require little computational capacity, allowing the
issue to be tackled in real time through autonomous systems such as drones.
3) PROTECTING WILDLIFE
The International Anti-Poaching
Foundation (IAPF), spearheaded
by Damien Mander, trains Green
Army rangers to protect animals
through direct action
They often use technology to
monitor the animals’
whereabouts and livelihood.
The group uses surveillance
technology such as thermal imaging
cameras, aircraft, and drones, which
can produce some incredible
photographic images. The idea is to
monitor as much of the land that the
animals live on to prevent poachers
from killing wildlife
4) CLIMATE RESEARCH
Climate research is possibly one of
the pioneering fields in the use of
drones for civilian purposes.
Already towards the end of the
1990s, some US universities were
using unmanned vehicles to
measure the changes in the Arctic
ice in places man couldn’t reach.
Their many applications allow us
to 1)Count animal populations
2) Detect changes in seawater
temperatures.
3)Measure the thickness of the
ice
cap.
Camera Traps
A camera trap is a remotely activated camera
that is equipped with a motion sensor or an
infrared sensor, or uses a light beam as a trigger.
Camera trapping is a method for capturing wild
animals on film when researchers are not
present, and has been used in ecological
research for decades.
How it takes the photo?
Camera traps take photos when a sensor is
triggered by the movement of an animal or
person and, increasingly, send the image in
real-time to the operator.
Some discoveries…...
In recent years, the use of camera traps has led to major discoveries,
including documenting an Amur leopard (Panthera pardus orientalis)
in China for the first time in 62 years;
proving that the world's rarest rhino, the Javan (Rhinoceros
sondaicus), is breeding, by photographing a female with her calf;
rediscovering the hairy-nosed otter (Lutra sumatrana) in the Malaysian
state of Sabah; recording the first wolverine (Gulo gulo) in California
since 1922;
taking the first video of the rare Bornean bay cat (Pardofelis badia);
documenting the elusive short-eared dog (Atelocynus microtis)
preying on an amphibian in the Amazon;
proving the extremely rare Siamese crocodile (Crocodylus siamensis)
still inhabits Cambodia;
and snapping the first-ever photographs of a number of species in the
wild, including the Saharan cheetah (Acinonyx jubatus hecki) and the
giant muntjac deer (Muntiacus vuquangensis) in Southeast Asia.
Camera traps have helped land managers spy on the movements of
over-abundant elk and conduct inventories of wildlife roaming on
conservation easements.
Some common uses ……….
Camera traps could be used in rainforest canopies
to study birds, reptiles, and monkeys, and
underwater cameras could document marine
wildlife and the fauna of lakes and rivers. With
further technological advances, it may even be
possible to use tiny cameras to document the
world's micro-species, from stag beetles to brushfooted butterflies.
Provide data on exactly where species are, what they are doing, and
how large their populations are. They can be used to build up a picture
of whole communities of species, including how they are structured
and how species are interacting over space and time. Camera traps
are also being deployed to understand how humans and livestock
interact with wildlife.
The development of networked camera traps, capable of sending
images over phone or satellite networks in near real-time, has
provided a new tool in the fight against poaching. New software tools
and statistical models are also making it much easier and faster to
obtain high quality information from the thousands of images that
camera traps can quickly generate. This is improving our
understanding of human impacts on wildlife, and helping land
managers make better decisions at both small and large scales.
ELECTRIC CARS
INTRODUCTIO
N
“Electric cars” generally refers to road going
automobiles powered by electricity. Propelled
by one electric motor or more using batteries
. Electric motors give instant torque, and
smooth acceleration.
WHY ELECTRIC CARS?
• Automobiles are a necessary evil, while they have made living easy
and convenient, they have also made human life more complicated
and vulnerable to both toxic emissions and an increased risk of
accidents.
• According to the EPA(United States Environmental protection
Agency), motor vehicles collectively cause 75 percent of carbon
monoxide pollution in the U.S. The Environmental Defense Fund
(EDF) estimates that on-road vehicles cause one-third of the
air pollution that produces smog all around the globe, and
transportation causes 27 percent of greenhouse gas emissions.
• EFFECTS: The major pollutants which are emitted by automobiles
are Hydrocarbons , Carbon Monoxide (CO) , Nitrogen Oxides(NOx)
and other particulate matter which can lead to diseases like
asthma liver failure, cancer and carbon monoxide poisoning ,
Environmental effects like acid rain , growth of algae and many
more major problems and diseases in plants and animals.
NEED OF ELECTRIC CARS
• Less maintenance.
• More efficient .
• Cost Effective.
• Contributes to cleaner air.
• To preserve the fossil fuels.
• They produce up to six times less
carbon emissions over their lifetime
than a petrol car.
CONCLUSION
• To conclude ,advanced
technology in the form of electric
can thus help in reducing air
pollution and other major
environmental problems , only if
they are used WISELY!!
