Part B
(Read the Stories/Cases/Data set as the case may be, and answer ALL questions. Each FULL question carries 10 Marks.)
Sample Story/Case 1
Air pollution in Asia has worsened since 2000 and is responsible for deaths of thousands of people in Beijing, Jakarta, Seoul and Manila. The pollution is a result of the use of fossil fuels by the industry and transport sectors. The problem got aggravated in Asia due to the use of poor quality fuel, inefficient method of energy production, use of vehicles in poor condition and traffic congestion. This was revealed during a research conducted by World Bank and Stockholm Development Institute. The research states that air pollution in the continent has surpassed the combined emissions in Europe and North America. The deaths caused by fine particulate matter far exceed those caused by sulphur dioxide, nitrogen oxide, ozone and lead. The health cost in major Asian cities now exceed for 15-18 percent of urban income expenditure, claims World Bank officials.
Module 1
QB1. (a). Identify any one component that need to be addressed towards attaining social, economic and environmental sustainability in the case illustrated.
(1+1+1)
(b). Compare the given situation in the cities stated in the text with any major Indian city. Do you see any such catastrophe to happen/is happening here? Why?
(1+2)
(c). Which multilateral environmental agreement(s) in the past think was proposed to curb the growing impact of pollution on humanity specific to the nations discussed here? Also highlight the instrument of action that is applicable in this context.
(1+1)
(d). A project under Clean Development Mechanism is to be proposed to contain the growing air pollution in the countries discussed, at the same time tackling a development initiative. Could you propose a CDM initiative that might be used in all the regions discussed here? Focus your answer showing the impact on the populace and the activity. (2)
Module 2
Q. B2 (a). A comprehensive campaign to address air pollution need to be launched through school children, what programme would you envisage for this. What is outcome anticipated? (3)
(b). There is a sudden decision to remove all vehicles from the road that fails to meet specified norms of emission level within a specified time period. As part of citizen forum you are requested to give views on the enforced regulation. State your views on this. (3)
(c) A massive campaign on environmental degradation is to be initiated. Bring out a slogan and the key message that need to be addressed. (2)
(d). Suppose you are a Carbon Credit Auditor appointed to assess the greenhouse gas emission reduction strategies. Identify a component of assessment and brief the methodology that could be adopted in connection with this. (2)
Sample Case 2
Case on Ecological Habitat Development
The project on ecological housing in Setagaya-Ku Fukasawa Tokyo, Japan provided environmentally sustainable housing in one of the most densest cities of the world with the normal public housing cost financed totally from public funds. Five apartment buildings were constructed with 70 dwellings, 43 of which were for low income residents. High levels of
thermal insulation and technologies saving energy such as solar collector for heating and hot water, solar cells and wind turbines were attached and water saving techniques such as permeable pavement and rainwater collection were installed. Various passive lighting, heating and cooling methods were applied and the design was made according to local wind patterns to enable natural ventilation during hot and humid summers. The building materials were selected to have minimal impacts on the environment and health of residents. Many trees were preserved and moved to the site, a garden established, a green rooftops installed, which is important in the context of low urban greenery and a major heat island effect. Thirty percent saving of average household energy bills were achieved. Shared community facilities were constructed. The project had a social dimension resulting in a social mix that is very rare in Tokyo.
Module III
Q. B3. (a). Highlight the significance of life cycle cost evaluation when applied to such projects to
establish the advantage of environmentally sustainable housing projects. (3)
(b). If you are asked to evaluate the environmental impact of the above project, state any two factors that can be identified as the key impacts on the environment. Also specify the necessary information required for the assessment of impact due to these factors. (4)
(c). If standardisation of these practices need to be attained how can ISO 14000 help the organisations to ensure quality of practice in environmentally sustainable housing projects? (3)
Module IV
Q. B4. (a). Identify any three interventions made in the given project (case 2) to ensure energy efficient construction practice. (3)
(b). The project had also initiated large number of green buildings practices. Mention any two cases followed to make the practice green and also justify your claim appropriately (2+2)
(c). The project have tried to address social, environmental and economical dimension of habitat development. Identify any one step taken by the implementing agency to address each of the three parameters and also state how you would see these steps from Kerala perspective. (3)
Sample Case/Data 3
Module V
Q. B5. (a). The energy use policies have had serious impact on sustainability. Justify the statement based on the energy use pattern across the century (1900 to 2000) (3) (b). If the trend shown in this is expected to continue sketch a simple graph to estimate the energy use by the year 2050. (3)
(c). Among the different energy sources shown in the figure which one was the most recent to supply to energy needed for development? How do you see the potential of this energy source for future? Provide appropriate justification for your answer. (4)
(Another typical evaluation-level question that may be asked based on the given case, in Module V is as follows:
The biomass energy supply doesn’t show a significant change in consumptive rate. What according to you could be a reason for this situation? )
Module VI
Q. B6. (a). If industrial energy use is the dominant consumer of energy. Give any three suggestions for reducing the energy consumption in industries. (3) (b). Give a short account of pollution faced due to the prevailing practice of growth represented in the figure. (3)
(c). If the given graph represent the blueprint of prevailing energy use, What suggestions would you propose to reduce the conventional energy use by 25 %. State any two steps initiated and how they are used to attain the anticipated reduction levels. (4)
(Another sample question related to case 3, and in Module VI, may be as follows:
Q. Going green can reduce the overall energy use. Mention any one strategy that you could adopt to meet the sustainability benchmarks).
