(xi) Strategies for conservation of biodiversity - insitu and exsitu. Looking at various in-situ and ex-situ strategies for their efficacy and viability. In-situ - protected areas (biosphere reserves, national parks, wildlife sanctuaries). Ex-situ - captive breeding, zoo, botanical garden, gene banks. (xii) Mitigating people- wild life conflict. Evolving strategies to mitigate people-wildlife conflict, especially for the communities staying close to forests or even within forests - fences or trenches around communities, building waterholes within forests, providing food for animals during times of drought to prevent them from straying outside the forest areas, maintaining a buffer zone between forest and human habitation, preventing human encroachment into forests. Preventing poaching by creating or increasing livelihood opportunities, involving local people in conservation by providing suitable incentives.
2. Environmental Management
(i) Need for environmental management vis-ŕ-vis development. Understanding that from the development point of view, environment may mistakenly be seen as a ‘resource’ to be exploited, whereas, environment needs to be viewed as a ‘capital’ that needs to be managed carefully. (ii) Aspects of environmental management - ethical, economic, technological and social. Understanding different aspects of environmental management as mentioned above. Ethical - e.g. ensuring inter and intra generational equity, gender equity, etc. Economic - e.g. Extended Producer  Responsibility [EPR] taken up by companies  in several countries - the producer of a product takes responsibility for the product after its life is over e.g. battery companies taking back batteries after its life. Technological - developing technologies that do not harm the environment - alternate  technology products like solar cooker, solar car, biogas, etc. Social - processes and policies that ensure social equity - use of commons and forests, urban land use, equitable representation and  participation in local governing bodies.

for the purpose of discussion and not for testing). (viii) Role of national and international agencies. (both governmental and non-governmental). Understanding the role of agencies in creating awareness, framing policies, implementing laws and mobilising people.
4. Sustainable Agriculture
(i) Need for sustainable agriculture. Understanding that modern agriculture is causing increasing amounts of land to be desertified, through the need to produce ever increasing quantities of food to feed the growing population. To understand that on the one hand the
demand for food is increasing due to population growth and on the other hand the land available is decreasing due to the impact of modern chemical farming. (ii) Green revolution - impact on environment. Introduction to Green revolution - Development of High Yielding Varieties (HYV); introduction of fertilizers and pesticides; consequences of using fertilizers; consequences of using pesticides on population of living organisms; contamination of soil, water, food, impact on human health; long term effects - increased incidence of cancer, malfunctioning of endocrine system, etc. Study of the impact of DDT. (iii) Importance of soil for crops. Role of soil biota in maintaining health of soil. (iv) Irrigation systems, use of manure and fertilizers. The role of irrigation in traditional agriculture. Traditional irrigation systems (micro, indigenous systems) vs. modern systems like large dams with their vast canal systems. Advantages of such macro systems, (like larger areas of cultivation) and disadvantages (like water logging). (v) Crop protection - measures for control of pests– agrochemicals. Study of a few traditional methods of pest deterrence vis a vis modern methods of pest control - viability of traditional methods in today's scenario and limitations and dangers of modern methods.  Role of agrochemicals in increasing food production.
(vi) Impact of agrochemicals on environment. Study of a few commonly used agrochemicals
and their impact on soil, water and air. (vii) Elements of sustainable agriculture -mixed farming, mixed cropping, crop rotation, biological and economic consideration, use of  bio-fertilizers and bio-pesticides, biological pest control, integrated pest management. Self-explanatory. (viii) Application of biotechnology in crop improvement. The scope biotechnology offers in developing favourable traits in crops, like pest resistance, drought resistance, salinity resistance. (ix) Management of agricultural produce - storage, preservation, transportation and processing. Understanding the dynamic of movement of
agricultural goods from producers to consumers - understanding that tremendous amount of grain is lost to rats and spoilage due to poor storage facilities; food processing increasingly seen as a favourable option as it has a larger shelf life and brings about more revenue.
PAPER II – PRACTICAL/PROJECT WORK
Classes XI and XII
The practical/project work carrying 30 marks needs to be undertaken under the guidance of the teacher. The project will be evaluated by a Visiting Examiner (who has specific expertise in the content of the project work) appointed locally and approved by the Council.(For Class XI, Project Work may be evaluated by the teacher). Exemplar Projects and Activities It is expected that the students will undertake at least two projects or activities in each year, one of which should be undertaken individually and prepare a report in each case. Projects and activities may be planned and designed depending upon the local situations, available resources and environmental issues of concern. The projects and activities given below are only suggestive and not prescriptive. 1. To study the changes that have taken place in a given land area of a city/village/locality/market during the last five years in respect of at least five parameters like number of houses, residents and families, food habits, number of household goods in a family, consumption of water, electricity and fuels including that for personal vehicles by a family, sources of noise (public address systems being used, television, radio and vehicles on the road), common facilities like number of schools, hospitals, shops, theatres, public convenience, public utilities, public transport; number of' factories, industries and/or the facilities for, production and processing of goods, loss of water bodies, types and quantity of wastes, their disposal and treatment facilities with a view to discussing the patterns of changes and impact on the environment and quality of life. A specific project on these aspects may be: - To study the changes that have taken place in a given land area during last five years in respect of number of houses, residents and families and prepare a report on their effects on civic amenities like availability of water, electricity and fuels; drainage-system, disposal of wastes including  night soil. 2. To study the environmental profile of a town/locality/village in respect of population density, green cover, educational level of residents, social problems and sources of pollution and their effect on air, water and soil. 3. Improvise two models of greenhouses of same dimensions made from low cost / no cost materials. Place them in open under identical conditions and put some potted plants in one of them. Note the temperature inside and outside both the greenhouses every two hours from dawn  to dusk for two weeks. Explain the reasons for the differences in temperature, if any, between the two green houses. 4. Collect data on monthly consumption of electricity and fuels from at least five families, any two commercial establishments and for public utilities in a given locality. Plan strategies to educate consumers to economize the consumption of electricity and fuel by reducing their over use, misuse and improper use. 5. To study for a period of one month the status of sanitary conditions and methods of waste disposal of a given locality vis-ŕ-vis the role of Panchayat, Municipality or Corporation and prepare an action plan to make the conditions more environment friendly. 6. To investigate impact of an industry or a large manufacturing unit on local environment. The parameters could be land use, ratio of covered area and open space, raw materials used for production, inputs like electricity, water or any 22 other, types of waste generated and modes of waste disposal, use of environment friendly and efficient technology, types of pollutants emitted or discharged, average health status of the employees and residents in the area. 7. To study the impact of changes in agricultural practices or animal husbandry including poultry, piggery, fishery, apiculture over a period of time in a given locality or village on local environment. The components for analysis may include: types of crops, land area under cultivation, mechanization, use of electricity, mode of irrigation and agrochemicals, agro- astes and their disposal, types of breeds and animal feed, types of shelter and health care, methods of preservation and processing of products, animal wastes and their disposal. Suggest an action plan to modify the prevailing practices so as to make them environment friendly and sustainable. 8. Collect samples of water from different sources and study their physical characteristics like turbidity, colour, odour; measure of pH, nature of suspended and dissolved impurities and pollutants, presence of toxic materials by testing presence of mercury, lead, arsenic, fluorine and presence of living organisms. Test the presence of toxic materials and living organisms with the help of local laboratory or institution may be taken, if available. Identify the most polluted sample of water and locate the sources of its pollution. Devise an action plan to mobilize public opinion for checking the pollution. 9. To study the practices followed in the region for storage, preservation, transportation and processing of perishable or nonperishable farm products and to assess the extent of wastage due to faulty practices. 10. To study the status of an endangered species listed for the region by collecting information through different sources and observation, if possible and to assess the reasons for its diminishing number. Suggest ways and means to protect the species. 11. To prepare a status report on prevalence of child labour in a given area through simple surveys on children engaged as domestic help and as workers in farms, commercial establishments and manufacturing units. The survey may be in respect of age group, education, wages, working hours, working conditions, safety in work place, health, handling hazardous materials and the like. Units dealing with hazardous materials and processes may be identified and an action plan to mobilize public opinion against practice of child labour may be prepared. 12. Conduct a survey of plants and trees in the locality and collect information about their cultural, economic and medicinal values from local people and available literature. Prepare an action plan for the propagation of trees that are most valuable in terms of their cultural, economical and medicinal use. 13.
