  1. ENVIRONMENTAL STUDIES

  2. Key Terms: Ecology Environment Environmental Studies • Why Environmental Studies? • Objectives, Scope & Importance of the course

  3. ECOLOGY • Ecology is the science studying the interactions of organisms with their Environment and with one another. It comes from the Greek words ‘oikos’ (home/habitat) and ‘logos’ (study/science).

  4. What is Environment ? • The term is derived from a French word ‘Environ’ which means ENCIRCLE. • Scientifically Environment means all of the outside forces, events, and things that act on a thing. The environment is everything that is around something.

  5. It is the complex set of physical, geographic, biological, social, cultural and political conditions that surround an individual or organism and that ultimately determines its form and nature of its survival. – from World Bank report on education It includes: 1) All factors living and nonliving that affect an individual organism or population at any point in the life cycle. 2) Set of circumstances surrounding a particular occurrence. 3) All the things that surrounds us.

  6. Environmental Studies ? • Environmental studies deals with every issue that affects an organism living on the earth. • It is an applied science as its seeks practical answers to making human civilization sustainable on the earth’s finite resources. • It is essentially a multidisciplinary approach • Its components include Biology, Geology, Chemistry, Physics, Engineering, Sociology, Health Sciences, Anthropology, Economics, Statistics and Philosophy.

  7. INTRODUCTION • Not just collection of information • For awareness – social and individual • Conflict between development and environmental conservation • BALANCE At one end it studies how the life process of a tribal community protects the environment surrounding it; On the other hand it probes what will be the effect of state of the art technology on human environment! Thus the scope of environmental studies is extremely wide and covers some aspects of nearly every major discipline.

  8. Objective of this Course • Develop CONCERN for our own environment. • The concern leads us to ACT at your own level to protect the environment we all live in.

  9. The three reasons for studying the state of the environment • There is the need for information - the need to use resources more equitably. • There is a need to change the way - based on observation and self learning. • pro-environmental action - including activities we can do in our daily life to protect it.

  10. ????WHY WE HAVE TO STUDY A COURSE IN ‘ENVIRONMENTAL STUDIES’ ???

  11. 1. Is there any way out ! If I want degree I got to do it!! • It is prescribed in the Syllabus and carries 3 Credits. If I want to get through 1st year and finish my degree in 4 years, I have to do it!!

  12. 2. Legal Obligations Supreme Court in it’s judgment has made learning of the subject mandatory at under graduate level (1991). University Grants Commission has directed all affiliated institutions to compulsorily teach the subject, for all the branches of engineering (2004). M.I.T. has introduced the subject at I year level as a core subject, in compliance with UGC directive (2005).

  13. 3. We are Victims of our own acts Our Consumption pattern & Lifestyles Indiscriminate Use of Natural Resources Pollution from production Of Artificial Resources Degradation of Our Environment We ourselves are Victims

  14. 4. You are going to be Modern day Professionals Being Modern day Professionals, You will be required to encounter Environment related problems at all levels- Most importantly as Technical Managers directly facing the Society at large. What do You Mean by this ? In what way we are responsible ?

  15. Industrial Investors Technical Professionals Society in General SOCIETAL PYRAMID OH! We are a class of our own!!

  16. Industrial Usage Basic Societal Usage RESOURCE DISTRIBUTION PYRAMID But our base is shaky!! We got to face the music !! Bosses will ask you to face the public !!

  17. WHY SHOULD WE TEACH ! “If you plan for one year, plant paddy. If you plan for ten years, plant trees. But if you plan for hundred years, educate people.”

  18. No Water? Drink Thanda!Case Study of Plachimada • A Soft Drink bottling unit of company X was established in Plachimada, a village in Kerala state, in the year 2000. Company dug bore wells to extract clean drinking water for soft drink. Company had obtained clearance from the state’s Environment Monitoring Authority and had been permitted by the local body to start the production. • Production unit was extracting water to an extent of 3,50,000 Liters Per Day (LPD) { 3,50,000 LPD means per capita daily consumption of 5,000 people.} Unit in it’s full production capacity had planned to draw 15,00,000LPD of water { Equal to LPCD of 21,430 people.}

  19. No Water? Drink Thanda!Case Study of Plachimada (Cont…) • By 2002, all the open wells- they were the main source of water for the people- not only in the village , but surrounding 10 villages dried out. With most common life sustaining resource not available, people were pushed to desperation. • They started mass protests against the company and demanded immediate closure of the unit. The local body sensing the heat of people’s anger, withdrew the permission to run the unit. • The company has sought the intervention from the court of law and the litigation is in Highest court of the land. Mean while, there is no respite for company from protesting public. The protest has spread not just across the region but across the world !

  20. HENCE THERE IS AN URGENT NEED TO UNDERSTAND THE PROBLEMS WE ARE FACING AND FORESEE THE CALAMITIES THAT MAY FALL ON US IF WE DO NOT HEED THE RATIONAL WARNINGS. WISE PEOPLE SAYBETTER TO BE LATE THAN NEVER

  21. Scope and Importance • Natural and Man made Environment • When we look around the area we live in (natural surrounding) it was originally a forest, a river, a mountain, a desert or a combination of these – the natural landscape. Modified heavily by human beings!

  22. Web of life? • We use water – drink and other activities • We breath air • We use resources – food is made • We depend on community of living plants and animals – forms the web! - we are a part it.

  23. Our dependence on nature is so great that we can’t continue to live without protecting earth’s resources • Most traditions refer our environment as “Mother Earth” and learned respecting nature is vital for their livelihoods.

  24. Agriculturist • industrialist • Application of technological innovations. eg: BT cotton, megadams, industries, fertilizers and pesticides. • Natural resources: use of large amount of natural resourses like water, minerals, wood, petroleum products etc. • Exhaustion of nonrenewable resources: minerals, oils etc if used extensively with out any thought for present and future generations. • Natural resources can be compared with money in our bank.(Sustainable utilisation). • Consumer oriented society

  25. Limited Natural Resources • Added to this is misuse of resources. We waste or pollute large amounts of nature’s clean water. • Water Pollution (Gastro-intestinal diseases and many pollutants are known to cause cancer) • We create more and more materials like plastic that we discard after a single use; and we waste colossal amounts of food, which is discarded as garbage. • Air Pollution (Respiratory diseases) • Industries – Fertilizers, waste generation • Way of life – vehicles, plastics

  26. Manufacturing processes create solid waste byproducts that are discarded, as well as chemicals that flow out as liquid waste and pollute water, and gases that pollute the air. Increasing amounts of waste cannot be managed by natural processes. These accumulate in our environment, leading to a variety of diseases and other adverse environmental impacts now seriously affecting all our lives.

  27. In such a alarming state of affairs, Improving this situation will only happen if each of us begins to take actions in our daily lives that will help preserve our environmental resources. We cannot expect Governments alone to manage the safeguarding of the environment, nor can we expect other people to prevent environmental damage. We need to do it ourselves. It is a responsibility that each of us must take on as ones own.

  28. DR. A. P. J. Abdul Kalam 's Speech • Once in an interview, the famous Ex-municipal commissioner of Bombay, Mr. Tinaikar, had a point to make. 'Rich people's dogs are walked on the streets to leave their affluent droppings all over the place,' he said. 'And then the same people turn around to criticize and blame the authorities for inefficiency and dirty pavements. What do they expect the officers to do? Go down with a broom every time their dog feels the pressure in his bowels?In America every dog owner has to clean up after his pet has done the job. Same in Japan.Will the Indian citizen do that here?' He's right. We go to the polls to choose a government and after that forfeit all responsibility.We sit back wanting to be pampered and expect the government to do everything for us whilst our contribution is totally negative. We expect the government to clean up but we are not going to stop chucking garbage all over the place nor are we going to stop to pick a up a stray piece of paper and throw it in the bin. We expect the railways to provide clean bathrooms but we are not going to learn the proper use of bathrooms.We want Indian Airlines and Air India to provide the best of food and toiletries but we are not going to stop pilfering at the least opportunity.This applies even to the staff who is known not to pass on the service to the public.

  29. An Overview of Present state of Affairs In order to appreciate the vast areas of Environmental Concerns which this subject aims to address, it is needed to have a bird’s eye view of the present state of Environment at both National and International levels. He are some quick points:

  30. PRESENT ENVIRONMENTAL ISSUES OF GLOBAL CONCERN The main environmental issues today are wide ranging and all-encompassing: deforestation, biodiversity, soil erosion, climate change, pesticide build-up, industrial and municipal pollution. Main cause: anthropogenic interventions in the natural and self-sustaining cycles. All these problems can be categorized into three main issues: • Population explosion • Land degradation • Environmental pollution: Industrialization, agriculture/fertilizer/pesticide/green house gases, air pollution, acid rain, ozone depletion, green house effect, water pollution, deforestation.

  31. Environment Problems in India Environment problems in India can be put into three classes: • Poverty • Problems arising as negative effects of the very process of development. • Problems arising from improper implementation of the directives and laws of Environmental protection.

  32. Unsustainable use: • Over draft/use, Misuse/Unwisely use, Wastage, Greed/Need, etc. – leads to stress! • Short term economic benefit – indicator of progress! v/s Long term ecological benefit Result: Forests – disappear Rivers – run dry Deserts – spread Air, Water, Soil – polluted Conclusion: Human well being seriously affected!

  33. For every resource to use, we must ask questions ourselves: • For every resource to use, we must ask questions ourselves: • Where does it originate? • Who uses it most intensively? • What is the value of resource? • How is it over used / misused? • Who is responsible for its improper use? (Resource collector/middleman/enduser) • How can we help to conserve it and prevent its unsustainable use?

  34. ASSIGNMENT – I • Activity 1 • Take any article that you use in daily life –a bucket full of water, or an item of food, a table, or a book. • Trace its components journey backwards from your home to their origins as natural resources in our environment. • How many of these components are renewable resources and how many non-renewable? • Activity 2 • Try to answer the following questions for one of the components in the article you chose in activity 2: • Are you using that resource unsustainably? • In what ways could you reduce, reuse and recycle that resource? • Is there an unequal distribution of this resource so that you are more fortunate than many others who have less access to it?

  35. Syllabus Unit 1 : Multidisciplinary Nature of Environmental Studies Unit 2 : Natural Resources Unit 3 : Ecosystems Unit 4 : Biodiversity and its Conservation Unit 5 : Environmental Pollution Social issues and the Environment Human Population and the Environment

  42. Values of Nature • Productive value • Aesthetic value, recreational value • Option value

  43. Productive Value of Nature • Biotechnology is fast advancing in this modern world. • Nature has species which contain an incredible and uncountable number of complex chemicals that are raw material and can be used for developing new medicines and industrial products. • Destruction of these species due to human activity is happening rapidly and hence these species might become extinct in near future. • Hence there is an urgent need to protect these species • Protection of these species by individual or group efforts.

  44. Aesthetic and Recreational Value of Nature • Nature encompasses every aspect of living (biodiversity: flora and fauna) and non-living (sea, forest, desert) part of the earth. • Nature enlivens our existence on earth. • Developing national parks and wildlife sanctuaries in relatively undisturbed areas. • Enjoy the wilderness – nature tourism or wildlife tourism – pleasurable experience and also creates a deep respect and love for nature. • Urban setting there will be green spaces and gardens – psychological and physical health of city dwellers and provides aesthetic value and visual appeal. It also gives access to certain amount of peace and tranquility.

  45. The Option Values of Nature • Day-to-day activities have adverse impacts on nature’s integrity. • Present generation’s lifestyles and economies are based on unsustainable pattern which can lead to destruction of biodiversity and will leave nothing for future generations. • Option value: nature provides us with options to utilize it resources which we can use it either greedily (destroy its integrity and long term values) or sustainably and reducing our impacts on environment. • Allows us to use its resources sustainably and preserve its goods and services for the future.

  46. Need for public awareness • Sustainable use of natural resources • Join an environmental group (YISF) • Prevention is better than cure (Prevention of Environmental degradation) • Mass media (News papers, Radio, T. V. etc.,) • Activities concerned with students • Be a volunteer in environmental organizations that fight for saving the Earth • Reading news papers or articles which emphasizes on environmental issues • Practice and promote 3 R principle (Reduce, Reuse and Recycle) • Practice and promote good civic sense (No smoking and no spitting in public places) • Spend time in natural habitat • Take part in events – world environmental day etc.,
