According to David Lin (pers comm 2020) of the Global Footprint Network
(Oakland, CA), there are quite a few steps before even beginning the calculation
used by the Footprint Calculator. The National Footprint Accounts is the base
dataset, which must be categorised into consumption categories. This is done first
by applying the National Footprint Accounts as an environmental extension to a
Multi-Region-Input-Output (MRIO) model. From this MRIO model’s outputs, the
Global Footprint Network then develops the Consumption Land-Use Matrix
(CLUM) based on category concordances. Then CLUM serves as the basis of a
hybrid top-down and bottom-up calculator. All these processes are quite complex,
and there are very few publications on this. One recent publication by Collins et al.
(2020) addressed role of personal Footprint calculators in helping people understand
how to live within the limits of one planet. This article also contains a mini review of
previously published articles and books dealing with calculators to consider the
contribution of personal Footprint calculators.
4.4.4 (4) Follow-up Interviews
Semi-structured follow-up interviews were based on the following main survey
questions:
1. What type of crops do you grow, and in what proportion?
2. How much do you grow in a year?
3. Where do you sell your crops?
4. Are you participating in Fair Trade or organic farming?
5. Do you use fertilisers or pesticides?
6. Do you benefit from Payments for Ecosystem Services?
7. Have you ever been approached before to complete a survey or an interview?
These questions were administered in person in the presence of a translator,
obtained most often with oral (rather than written) informed consent. Up to four
survey-interviews per group per day across 12 days in February to March 2020 was
enough to draw a sufficiently large sample in excess of 96 farming households
located in the corridor to enable engaging with a variety of household demographics,
farm sizes, and crop types. The interviews were structured around the survey
responses from each farmer survey (completed by household heads) based on the
Footprint Calculator, divided into the three main sections of the consumption
categories: food, housing, and transportation. The short follow-up interviews were
intended to supplement the closed-ended questions on the farmer survey (based on
Footprint Calculator), and expanded upon these to provide context using a few openended questions and any added commentary.
