“…3 Similarly, although land area measurement using global positioning systems (GPS) brings significant improvements over self-reported data (Carletto et al, 2015(Carletto et al, , 2017Dillon et al, 2019;Kilic et al, 2017), the consumer grade GPS devices used in many of these studies are likely to suffer from some inaccuracies when applied to smaller plots (Dillon et al, 2019;Keita & Carfagna, 2009). Second, a number of recent studies have argued that the relationship between land area and agricultural productivity depends on the choice of agricultural productivity indicator used (Arag on et al, 2022;Ayaz & Mughal, 2023;Garz on Delvaux et al, 2020;Helfand & Taylor, 2021). 4 Third, a recent literature highlights the role of the edge effect, whereby productivity is higher along the plot perimeter, in explaining why small farms (and plots) appear more productive (Bevis & Barrett, 2020).…”
