1) Ensure that the interviews are conducted with those people who cook the most in the household. Often it is not sufficient to say that these are “women”, as “women” might include different people - younger women, mothers-in-law, etc. To ensure that the right persons are interviewed, it is recommended to include a verifying question “Who does most of the cooking in this household?” If it is not the respondent and the person who cooks the most is not available to answer the questions, do not ask Q1 and Q2 above.
2) Examples of fuel-efficient cooking practices include: pre-soaking hard foods (e.g. beans); using a lid; using a pressure cooker, using a fuel-efficient stove; otherwise shielding / enclosing the fire and controlling air supply; using dry firewood; cutting food into smaller pieces before boiling; milling or pounding hard grains and beans; using locally acceptable tenderises; and cooking larger volumes of food or fluids / sharing cooking with other people (large pots help). Details on these and additional cooking practices are available in UNHCR’s publication provided below.
3) Ensure that the interviewers can probe neutrally to reduce the risk of a situation when the respondents follow certain fuel-efficient practices but forget to mention them.
4) Other ways of collecting the required data include:
- Conducting interviews where the respondents are asked about each promoted practice in turn and whether or not they follow them. The risk with this approach is that even though some people do not follow a given practice, they might still say that they do because this is expected of them. That is why this approach is not recommended.
- Another option is to conduct observations at a time when people are preparing their meals. While this is likely to be more accurate, it takes much more time than interviews.
- Alternatively, if you are primarily interested in the duration and intensity of cooking, you can consider using stove use monitoring sensors (SUMS). These inexpensive devices can collect usage data over a longer time by monitoring the temperature of the stove and the time. This gives very useful information on the usage pattern and under which conditions the stove is used. This is different data than those required by the indicator, but in some instances, they can be more useful (or at least complementary).
