Section B will consist of questions, which will require detailed answers. There will be a choice of questions in this section.

Theory – 100 Marks

1. Introduction

To give a broad introduction to the current environmental problems. To highlight the magnitude of these problems and to learn to appreciate the complexity of the issues involved.This is to be done through-

  • presenting facts and statistics.
  • inter-linking facts to generate a broad perspective.
  • understanding frameworks and systems that contribute to the problem under study.

Our main environmental problems

(i) Understanding ecosystems- threats and conservation measures.

Major causes of ecosystem destruction. The extent of forest cover left in India and the world today. For instance, India is left with about 4.6% protected forest cover. The rate of destruction. Efforts being undertaken to save the forests. Names of some organisations
which are involved and understanding of conservation measures. Examples of successful cases.

(ii) Resource depletion.

The consequences of major resources being depleted. Use of local and international examples. For example, petroleum products are likely to last only a few more decades.

(iii) Waste generation.

Issues of waste generation and disposal. A few prominent examples like dumping of nuclear waste and other hazardous wastes in developing countries by developed countries. Basel convention.

(iv) Economic disparities.

The extent of poverty in India and in the world. The nature of poverty in developed countries and developing countries – in rural and urban areas. Consequences and implications with reference to the lifestyles and aspirations of communities and society. Developmental paradigms and the politics of poverty.

(v) Land use.

Changing patterns of land use. Modern agriculture. Issues related to water.

(x) Endemic species.
Inter-relationship with other organisms, their evolution, the extreme adaptability to  local environments.

(xi) Keystone species.
Understanding that while all species have a niche, some species play a more critical role as they are keystone species, e.g. crocodile, sharks, fungi.

(xii) Kinds of ecosystems.
Study a range of ecosystems, the life that they support, their uniqueness, etc. Suggested Activities/Visits:

  • Visit a surviving ecosystem and do a rapid assessment.
  • Study natural communities of your neighbourhood like bird, insect population, etc.

3. Conservation of Ecosystems

(i) Conservation strategies:

  • Species approach including CITES.
  • Ecosystem approach including formation of National parks, sanctuaries and Biosphere reserves.
  •  Wildlife management.

What is the extent of forest cover left in the world? What are the threats faced by  forests? What are the different kinds of strategies that are being used to conserve forests? The above three are broad examples. Students should be made aware of the scope and limitation of the above approaches. Study an example of each kind.
(ii) Value of bio-diversity.
Study the value of bio-diversity from different viewpoints – ecological, economic, health,  food and aesthetic. Suggested Activities/Visits:

  •   Visit to a national park /any protected area.
  • Interaction with a group involved in conservation.

4. Dynamics of Development and Resource Use

Understanding development

(i) People as resources.
To gain an understanding that most development issues arise due to not recognising people as valuable resources. Importance of generating employment.

(ii) Impact of scale and kind of technology on resources. Understanding the model of modern development and the impact of industrialising and automating on the economy, people and resources. Shortterm and long-term accounting. Depletion of resources. Resource scarcity and economic consequences.

(iii) Urbanisation and its impact.
Causes and consequences of rapid, unplanned urbanisation – impact on infrastructure, services and provision of basic amenities.

(iv) Ecological footprint of a city.
Study two sample cities to see the extent of ecological impact on surroundings and also the actual extent of resource supply to the city. Extent of waste generated in a city in a day. Ratio of biodegradable and non-biodegradable matter. The need to sort garbage. E.g. Chennai generates 3500
tons of garbage a day of which only 800 tons is non bio-degradable. Dumping of hazardous wastes particularly in developing countries. The Basel convention.

Internal Assessment – 100 Marks

Students are recommended to complete two case studies and one project from the list given below. Suggested list of Projects/Case studies for topics from the syllabus-

Basic Ecology

Projects

(i) Where have all the sparrows gone?
Sparrows used to be one of the most common birds in India and are disappearing at a phenomenal rate across the country as has been recorded by various groups. Why has this happened? What could be the reason? They seemed pretty adaptive creatures and have inhabited human dwellings for a long time.
A study will help understand the fragility of a species’ existence on earth and the various conditions that could make it disappear.

(ii) Why conserve turtles?
Turtles have managed to survive for 200 million years and are now on the brink of extinction. Development of the last few decades has brought about this situation.
Studying this will help the student understand the reasons for the disappearance of turtles- the main reason being trawling and trawlers are not merely killing turtles.
Trawling is ravaging ocean ecosystems and creating under sea deserts. It will also help understand the role of turtles in ocean ecosystems. There is also much north- south politics around conservation like the Tuna dolphin issue and the shrimp – turtle issue.

(iii) Importance of green areas in a city.

(iv) Importance of mangroves.

Case Study

Study different kinds of existing ecosystems like the Sundarbans, the Sholas, rainforests, scrub forests, etc. for the bio-diversity they contain and the pressures they face. (Preferably an ecosystem that is nearby.)

Conservation of Ecosystems

Projects

  • (i) Zoos as places for conservation of species.
  • (ii) Insects as keystone species.
  • (iii) How can I conserve a piece of land in my neighbourhood?
  • (iv) Understand the conflict with the usage of CITES – Dolphins and Tuna, Turtles and Shrimp, Norway, Japan and whales, culling elephants in Africa, etc.
  • (v) Project Tiger, Project Elephant
  • (vi) The study of plight of Jarawas in the Andamans [Tribals and their relationship to the environment].
  • (vii) Protecting and conserving forests, rivers, oceans, etc; strategies, difficulties.
  • (viii) Is there effective legislation for addressing the environmental concerns?

Dynamics of Development and Resource use

Project

Conduct a study of a selected area.

Case Studies

(ii) Assessing the impact of women’s mobilisation and empowerment.

(iii) Child labour reports.

(iv) Development in a tribal region.

(v) Sourcing of livelihood in a traditional community.

(vi) Comparative studies.
When a student finds it too difficult to understand a context very different from his own, it becomes valuable to generate parameters by which one’s own context may be compared to that which one is studying. Alternately, it is possible to choose two related / opposite / parallel contexts and assess them through the same parameters. For example, if one is studying the usage of income in different economic classes, it is possible to compare expenditure on the basis of-

  •  primary requirements like food, shelter andclothing;
  •  entertainment;
  •  travel;
  •  buying of utility and luxury items;
  •  health;
  •  educational facilities;
  •  services, etc.

(vii) Consumer group reports.

Understanding Land Use

(a) Agriculture

Case Studies

  • (i) Public Distribution Systems (PDS).
  • (ii) Alternatives to PDS like the targeted PDS.
  • (iii) Starvation in Orissa & Andhra Pradesh.
  • (iv) Agricultural practices of a small and large farmer.

(b) Towards a world without hunger

Project
Is bio-technology the answer to the world’s food problems?

Case Studies

  • (i) The case of Bt Cotton.
  • (ii) Terminator and traitor technology.
  • (iii) The case of golden rice.
  • (iv) Bio-piracy.

Mapping – What I can do

By the end of the year the students would have gained exposure to various environmental issues. It is important for them to find personal solutions to many of the problems as this will empower them to find creative solutions to larger issues and the learning can be solution centred rather than problem centred. There are many areas listed which fall within the students’ scope of intervention. The students can be invited to choose the areas they would like to invest in.

(i) In my home.

  • a. Energy consumption -projects to minimise, eliminate, use alternate sources.
  • b. Fossil fuel usage – minimise, use public transport, cycle.

Guidelines for evaluating Project Work

The project has to be evaluated for the efficacy of the following steps:

1. Coming up with a clear question or problem statement, which will be the basis of the students project research. This is critical because without a clear question the research tends to be broad and unfocussed, with the student tending to gather whatever information is available rather what they need to have.
Criteria of evaluation for this stage will therefore include definition in terms of the focus and clarity of the question.

2. Formulating an action plan, which states the steps to be taken to move the question forward. Criteria of evaluation for this stage will include how pragmatically the plan takes the question forward.

3. Gathering primary data
50% – 70% of information gathered needs to be primary data i.e., data gathered by the student by going into the field.
This may involve evolving a questionnaire for social issues and formats for ecology related projects. Sample size and type have to be adequate and scrutinized carefully.
Criteria of evaluation for this stage will therefore be based on quantum of fieldwork and efficacy of sampling.

4. Secondary data
Secondary data from books, Internet and other publications is used only as a basis to substantiate, analyse and to construct an argument.
Criteria of evaluation for this stage will therefore include appropriate choice and use of secondary data.

5. Collating data and generating solutions
This phase after the gathering of the data is one of stock taking i.e. putting together of information. The data is then analysed and the solutions generated. The initial project report is put together.
Criteria of evaluation for this stage will therefore include sifting and organisation of relevant data, complexity of analysis in terms of number and relevance of parameter chosen and feasibility and innovation of solutions generated.

6. Project Report
The research the student does is submitted as a project report comprising of the following:

  • i. Statement of the topic, issue or problem being studied / researched.
  • ii. Statement of the action plan.
  • iii. Presentation of data using different methods such as bar charts/ pie diagram etc. A clear distinction has to be made between primary and secondary data.
  • iv. Analysis of data.
  • v. Solutions offered.
  • vi. Personal learning for the student.
  • vii. Bibliography and acknowledging resource persons.

Criteria of evaluation for this stage will therefore include readability, precision, neatness and  indexing.
Therefore the evaluation is on-line and does not base itself entirely on the project report.

7. Viva-Voce (Optional)

A viva may be conducted with the subject teacher and an External Examiner who could be another teacher from the school itself or an experienced person from the environmental field, preferably a researcher.

The purpose of the viva is to give the student an opportunity to converse with an expert in the field regarding his / her project. This would help to deepen the learning for the students and help them understand the lacunae in their thinking and process.

Guidelines for evaluating Case Studies

Case studies unlike projects are not based on primary data but entirely on secondary data mostly about a particular event or case.
The student presents it as a report about 1500 words long. It may be evaluated for:

  •  Comprehensiveness;
  •  Accuracy;
  •  Range of sources;
  •  Inferences drawn;
  •  Connections made;
  •  Perspective gained, etc.

Marks may be awarded on the following break up:
Project – 30
Case studies – 20
Total – 50

Evaluation

The assignments/project work is to be evaluated by the subject teacher and by an External Examiner. The External Examiner may be a teacher nominated by the Head of the school, who could be from the faculty, but not teaching the subject in the section/class.
The Internal Examiner and the External Examiner will assess the assignments independently.

Award of marks (100 marks)
Subject Teacher (Internal Examiner): 50 marks
External Examiner: 50 marks

The total marks obtained out of 100 are to be sent to the Council by the Head of the school. The Head of the school will be responsible for the entry of the marks on the mark sheets provided by the Council.
