25 TO 30 % Population of the country live incrowded and densely populated cities and major town

Employment Opportunities, Education, Medicare,

Infrastructural facilities,

Migration from rural to urban and semi urban citiesis regular and continuous process

1. More Vehicles Traffic congestion and Pollution2 . Consumer Life Style Solid W aste -> Unhygienic & Unsanitary

condition3 . More Built up area No Ventilation and vegetation4 . Aforestation More Temperature in Urban atmosphere5 . W ater Demand Ground water depletion and disappearance

of surface water bodies6 . Q uality of water & Air Polluted due to industrial and human

contribution7 . Life in Urban environment - more tough due to work pressure

and less comfort


7/25

Effective method of reducing migration trends to urban areas

Uniformly spreading of essential activities like Employment sector,Education Institutions, H ospitals, Transport Facilities

Govt Dept and H eadquarters to be shifted to towns as communicationfacilities

Development of satellites townships around major urban centes

To provide basic facilities in slum area

To reduce demand on power supply and alternative energy to besupplied

INDUSTRIALIZATION

Developing Countries and behind Industry

More the Industries Solid, Liquid, Gaseouswaste products are released

W aste products - depending upon the rawmaterials used and technology process used


9/25

Great leaders Visionaries have given priority for rapid industrialization in the name of development

Progress of the nation is associated with depletionand degradation of natural resources

Industrial pollutants are indiscriminately disposedwithout adequate treatment

Smoke from factory chimneys can affect human health

by causing breathing problems. Carbon dioxide in smokefrom car exhausts puts a neuro-toxin in the atmospherewhich lowers the intelligence level of children and

affects their behaviour. Carbon dioxide is also causingthe temperature in the world to rise. Other gases in

smoke cause acid rain which kills trees and fish.


12/25

Some industries give offvery unpleasant smellswhen they producedifferent chemicals orburn different materials.

Sometimes it can be alocal garage or industrialestate close to your homethat causes this type ofpollution.

Also, car exhaust fumesare causing breathingproblems in cities.

Many cities in the U.K. arenow thinking of banningthe car from city centres.

Remedies

W aste Product should be treated before it is left outfrom the Industry with prescribed standards

Polluting industries should be closed and heavypenalty should be imposed

Law should take its own action while controlling thepollution levels

A GRICULTURAL RE VOLUTION

AGRICULTURAL sector revolution has resulted in

1. T he construction of large dams

2. Fertilizer plants to bring more lands under cultivation

3. Increase in C rop yield


16/25

Side effects of Agricultural Revolution1. Storage reservoirs are leading to water logging which is

detrimental to the fertility of soil2 . Lands , Forests and villages are getting submerged due

to the constructions of water retaining structures

3 . H uman rehabilitations a major problem

4 . Fertilizers and pesticides used in agricultural fields are joining water bodies causing health hazards to humanbeing

R emedies Proper S election of water resourceprojects and using of natural fertilizers and bio

pesticides

Increase in Temp with altitude is know as an inversioncondition

This condition is unfavorable for the dispersion of

Pollutants

Valleys, Low laying areas and coastal areas areaffected as dense and cooler air stays below the warm

air


20/25

Affects due to inverse condition may bereduced if

1. Gaseous pollutants are minimized at source

2 . The stack height is adequately increased

3 . Care is taken at the time of locating the industries

Global W armingGreen house gases, Ozone depletionand pollution level causes for Globalwarming

Contribution to global warming due todeforestation , Industrial Units, Excess of energy use from human activities


22/25

H ARMFUL EFFECTS OF GLOBAL W ARMING

Climatic Changes ,Melting of Ice,Rise in Sea level,Submergence of Coastal W etland,

Change in Crop patterns,Dispersion of H armful chemicals,Effects on ecosystems and biodiversity,Change in H ydrological cycle,Change in Soil characteristics

All these process to be compensated by a process

known as Global Dimming


23/25

All these process to be compensated by a process

known as Global Dimming

Reduction of solar radiation in reaching the earth

surface with the increase in cloud , cover, aerosolsand particulates in the atmosphere


24/25

Global Dimming is a process working against globalwarming to some extent

2 to 4 % reduction in the amount of solar radiation isbeen observed
