AIR POLLUTION
CLIMATE CHANGE Change
The Principal Sources of Air Pollution are:Primary Pollutants are emitted directly from various sources and cause harm in theiremitted state. For example: NO, SO2,CO,CO2 etc.Secondary Pollutants result from chemical transformations in the atmosphere. Forexample: O3, H2O2, HNO3, H2SO4, Nitrate and Sulfate etc.
Simply said ‘Climate change is a long-term change in theaverage weather patterns that define Earth’s local, regional andglobal climates.’Technically, Climate Change refers to a statistically significantvariation in either the mean state of the climate or in itsvariability, persisting for an extended period. The major causeof this change is CO2 or other Green house gases due to AirPollution.
What is Global Warming?Global warming is the long-term heating of Earth’sclimate system observedsince the pre-industrialperiod (between 1850 and1900) due to humanactivities, primarily fossilfuel burning, whichincreases heat-trappinggreenhouse gas levels inEarth’s atmosphere.
Since the pre-industrial period, human activities are estimated to have increased Earth’sglobal average temperature by about 1 0 Celsius (1.8 0 Fahrenheit), a number that iscurrently increasing by 0.2 0 C (0.36 0 F) per decade. This is affecting our ecosystems &productivity
Weather vs. Climate
Weather refers toatmospheric conditionsthat occur locally overshort periods of time-from minutes to hours ordays. Familiar examplesinclude rain, snow,clouds, winds, floods orthunderstorms.
Climate refers to thelong-term regional orglobal average oftemperature, humidityand rainfall patterns overseasons, years ordecades.
Is climate changing ?Glaciers- Natural thermometers
"Glaciers in the Himalayan arereceding faster, if the present ratecontinues, the likelihood of themdisappearing by the year 2035 isvery high," says the InternationalCommission for Snow and Ice (ICSI)in its recent study on Asianglaciers.
The great Himalayan glaciers areretreating at the alarming rate of30-50 feet per year (10-15 meters).
Glaciers expand when climate cools and they shrink when it warms. Most glaciersaround the world are shrinking, proof that climate is warming.
Climate Change Theatre
A unique theatre to promote sustainabledevelopment, the theatre sensitizes themasses on Climate Change and globalwarming issues. This 18 meter diameter domeshaped building with seating capacity of 125persons. The theatre takes visitors around theglobe through a film, to explore theimplications of a warming planet, specificallyfrom the Indian perspective, and providesopportunity to understand and appreciate thelatest climate issues and the human role inmitigating and adapting to climate change.This show also educates visitors on renewableenergy and Sustainable Development issuesvia multi-screen projections.
RAIN WATER HARVESTINGScience City harvests 100% of rain water.
Rain water harvesting is a technique of collection and storage ofrainwater into artificially constructed tanks ( for later use) or innatural reservoirs, or the infiltration of surface water intosubsurface aquifers (before it is lost as surface runoff).
One method of rainwater harvesting is rooftop harvesting. Allbuildings of PGSC are connected through pipes to andunderground system which takes water harvested from the rooftops to a large pond (14,000 m3 capacity) specifically constructedfor the purpose. This water is later used for irrigation.
SPRINKLER SYSTEM
PGSC conserves water by use of sprinkler system in place of floodirrigation.
Sprinkler is a deviceused to irrigatelawns, landscapes,crops, etc. byapplying water in acontrolled manner inway similar torainfall.They are also usedfor cooling and forthe control ofairborne dust.
DRIP IRRIGATION
Drip irrigation is a typeof micro-irrigationsystem that has thepotential to save waterand nutrients byallowing water to dripslowly to the roots ofplants, either fromabove the soil surface orburied below thesurface. The goal is toplace water directly intothe root zone andminimize evaporation.
KARNAL TECHNOLOGY100% treated water generation throughSTP is used for irrigation.
Karnal Technology involvesgrowing tree on ridges 1m wideand 50 cm high wand disposing oftreated/untreated sewage water infurrows. The amount of effluentsto be disposed off depends uponthe age, type of plants, climaticconditions, soil texture and qualityof effluents.

Horticulture/ Irrigation
FAB(Fluidized Aerobic Bioreactor), a wastewater treatment technology, is a betteralternative to conventional waste watertreatment. A thin film on the mediaenables the bacteria to act upon the bio-degradable matter in the effluent andreduce BOD5/COD content in presence ofoxygen from the air used for fluidization.
SANITATION MANAGEMENTBio Toilet Demonstration and Use in PGSC
Bio toilet is a decomposition mechanized toiletsystem which decomposes human excretory wastein the digester tank using specific high gradedbacteria (aerobic or anaerobic) further convertingit into methane gas and water.
Hydrolytic, acidogenic, acetogenic andmethanogenic group of bacteria are used.

The Bio-digester technology has been developedby Gwalior based Defence Research andDevelopment Establishment (DRDE) and Tezpurbased Defence Research Laboratory (DRL).
WASTE SEGREGATION
According to Municipal Solid Wastes (Management and Handling) Rules, 2000municipal solid waste includes commercial and residential wastes generated ina municipal or notified areas in either solid or semi-solid form excludingindustrial hazardous wastes but including treated bio-medical wastes.
Municipal Solid Waste
It is the collecting, treating, and disposing of solidmaterial that is discarded and no longer useful.
Its sources are households; educational institutions;hotels; agricultural fields; industries, roads and railways;hospitals; places of recreation and tourism, etc.
Improper disposal can create unsanitary conditions andlead to pollution and outbreak of vector-borne disease.
Solid waste management involves technical, economic,administrative, and social challenges.
It is important to segregate waste at sourceand dispose it properly.
It is our responsibility to reduce waste and torecycle & reuse it, where possible, to protectthe environment and conserve our resources.
Solid Waste Management Classification of Solid Wastes• Municipal Waste• Hospital Waste• Hazardous Waste
Composting of organic waste,like food waste , paper, gardenand Agricultural waste.

RENEWABLE ENERGYState level Renewable Energy Park
The park is set up in 3.25 acre area withthe assistance of the Ministry of Non-Conventional Energy Sources (MNES) andPunjab Energy Development Agency(PEDA) to create awareness among themasses on use of various renewableenergy sources (Solar, Wind, Hydel, Tide,Wave, Geo Thermal etc), information onnew technologies developed in the areaof renewable energy and to educate themasses on energy conservation measures.Students can also see live example ofSolar Energy use (as PGSC meets its partialenergy demand through SPV).
Battery Operated Trains
The use of battery operated vehicleshelps to save energy and reducecarbon dioxide (CO2) emissions.
Evolution of Life
Evolution is the change in characteristics of a species over several generations . As per Darwin’s ‘Theory of Evolution’ all species gradually change over time. This happens by natural selection. Individuals in a species have differences in their
genes. Hence, they show variation in physical characteristics. Individuals which are best suited to their environment are more likely to survive,
finding food, avoiding predators and resisting disease. These individuals are morelikely to reproduce and pass their genes on to their children.
Individuals that are poorly adapted to their environment are less likely to surviveand reproduce. Therefore their genes are less likely to be passed on to the nextgeneration.
As a result those individuals most suited to their environment survive andgradually evolve.
To see how life evolved on the earth visit the ‘Panorama ofLife through Ages’ at PGSC

Evolution, Ecology and Ecosystems
Ecology is the interaction between organisms and their environment. It plays a significant role in forming new species An ecosystem includes all living things (plants/animals/organisms) in a given area
that interact with each other and the non-living environment (weather, earth, soil,atmosphere) that surrounds them
Major ecosystems are forests, grasslands, deserts, tundra, freshwater and marine.
Birds Gallery and Wetland EcosystemA gallery on Avian biodiversity showcasing avian wealth of the country.
Punjab is rich in aquaticresources which providehome to a large number ofresident and migratorybirds. It is, therefore,especially rich in Avian bio-diversity. A gallery on Birdbiodiversity showcasingwetland ecosystem alongwith various birds of eachState of India has been setup. It provides informationon avian wealth of thecountry and conservationissues.
BIODIVERSITY
FLORAL BIODIVERSITY IN PGSC
Biodiversity is the variety and variability of life onEarth. Biodiversity is typically a measure ofvariation at the genetic, species,and ecosystem level. Science City harbours richfloral and faunal biodiversity
PGSC harbours rich floral biodiversity with Cactus Garden, herbal garden andavenue of rare, endangered and threatened species. In all, there are morethan 168 plant species covering 144 genera and 58 families of plants. Cactusgarden has been developed in an area of approximately 4.25 acres. An herbalgarden has also been set up with a collection of medicinal and aromaticplants. Besides, Science City has beautiful collection of trees of Punjabhaving rich cultural and heritage value and Ashok Vatika.

Seismic Zones in India
India lies at the north western end of the Indo Australian Plate,which encompasses India, Australia, a major portion of the IndianOcean and other smaller countries. This plate is colliding againstthe huge Eurasian plate and going under the Eurasian plate. This process of one tectonic plate getting under another isresponsible for making India a earthquake prone area. A number of significant earthquakes occurred in and aroundIndia over the past century. Some of these occurred in populatedand urbanized areas and hence caused great damage.
The latest version ofseismic zoning map of Indiagiven in the earthquakeresistant design code onIndia [IS 1893 (Part 1) 2002]assigns four levels ofseismicity for India in termsof zone factors. In otherwords, the earthquakezoning map of India dividesIndia into 4 seismic zones(Zone II,III, IV and V) unlikeits previous version, whichconsisted of five or six zonesfor the country. Zones depicts highestlevel of seismicity whereasZone 2 is associated withthe lowest level ofseismicity.
Detailed guidelines for construction,maintenance and fire safety of thebuilding structures given by NationalBuilding Code of India are strictlyfollowed.All buildings structures are equippedwith Fire Fighting equipments as perthe mandatory requirement.
