The Panchayat Waste Survey: When Words and Bags Disagree
A Plus Two student in a Kottayam panchayat is doing her sociology project on household waste segregation. She plans a 12-item questionnaire and wants to survey 100 households drawn from the voters' list. In a pilot with 15 households, 13 respondents say they 'always' separate biodegradable and plastic waste. But when she watches the collection van on three mornings, only 4 of those 15 households actually put out segregated bags. The panchayat secretary wants findings before the 20th, the monsoon has flooded two lanes, and she has one assistant and two weeks. Her teacher says she should abandon the questionnaire and just observe. The student is unsure whether one method can capture both what people say and what they do. She also has not asked the ward member for a list of migrant tenants, who are not on the voters' list.

The pilot reveals a large gap between reported behaviour and observed behaviour. Thirteen of fifteen households claim they always segregate, but only four put out segregated bags on three collection mornings. This is best described as social desirability bias: respondents give the answer they believe is socially approved, especially when an outsider asks about a civic duty. It may also reflect faulty recall or a misunderstanding of what 'segregation' means in practice.
The problem matters because the project is about practice, not only attitudes. If the student relies on the questionnaire alone, she will conclude that segregation is widespread when the observed evidence suggests otherwise. Her recommendations to the panchayat would then be wrong: she might propose awareness campaigns when the real barrier is collection timing, lack of bins, or inconvenience.
The pilot also exposes a sampling-frame problem. The voters' list excludes migrant tenants, who may be a significant share of households. A survey drawn only from that list would systematically miss them. The lesson is that a method must be judged by the claim it supports: a questionnaire is useful for stated beliefs and constraints, but it cannot by itself measure disposal behaviour.
2. Recommend a feasible two-method design for her two weeks. Explain what each method contributes and how you would combine them.

A feasible design is structured observation plus a short interview, used on the same households so that the two sets of data can be compared.
First, draw a sample of about 40 households from two sources: the voters' list and a list of migrant tenants obtained from the ward member. On each collection morning, observe from the public lane whether the household has put out segregated bags. Record only what is visible; do not open bags or enter compounds. This gives a measure of actual practice and is cheap and quick.
Second, conduct a five-minute interview with one adult from each sampled household on a different day. Ask about knowledge of the segregation rule, bin availability, collection timing and difficulties. This captures reasons and constraints that observation cannot show. A short interview with the collection workers would add information about whether mixed waste is emptied into the same vehicle, which can discourage households.
Combine the data by comparing each household's observed and reported behaviour. Report the size of the gap rather than treating one as 'true'. The design is feasible in two weeks because observation happens on fixed collection days and interviews can be clustered in the same lanes. Avoid the flooded lanes until they are accessible, and note this limitation.
3. Identify two ethical issues she must handle when observing households' waste, and state how she should handle them.

The first issue is informed consent and privacy. Watching what a household puts outside its gate may feel intrusive, even from a public lane. She should explain the project to the ward member and, where possible, to the households, and give them the option to refuse. She should observe only from the public lane, not through gates or windows, and avoid recording names with the waste data.
The second issue is avoiding shame and stigma. If she photographs bags or names 'poor segregators', she may humiliate households, especially poorer ones who may lack bins or storage space. She should not take identifiable photographs, should report findings at ward or lane level rather than naming households, and should store data securely.
She should also get her teacher's and panchayat's approval, explain the purpose honestly, and make clear that participation is voluntary. These steps protect respondents and improve data quality: people who feel respected are more likely to give honest answers in the interview component.
