1) To assess whether more diverse production results in more diverse consumption, correlate this “production data” with “consumption data” gained by using IDDS or MDD-W or MDD indicators. In addition to this, you can also assess the proportion of harvested crops that were used for household consumption (you can do so, for example, by using ten stones representing the entire harvest and asking the respondent to divide them according to how the harvest was used - e.g. consumed, sold, donated ...).
2) Farmers often do not report the crops that they planted but due to crop failure or other factors did not harvest. That is why it is important to include Q2. Depending on the purpose of your survey, decide whether such a crop variety should be included or not.
3) Keep in mind that many farmers practice crop rotation. Therefore, if you are interested in crops that are not grown every year, you might need to extend the reference period (e.g. from 12 to 24 months). Assess the required recall period by interviewing local agriculture extension workers and more advanced farmers.
4) Consider including an additional question assessing why the farmers who replied “no” to Q2 could not harvest the given crop (for example, due to floods, pests, other factors?).
5) If your survey also assesses the Farm Diversity Score (FDS), there is no need to ask separately about the nutrient-rich crops you promote – you can just extract the information from the FDS data.
6) If you are also interested in how much of the given crop was produced during the previous season, use the Reported Agricultural Output indicator.
