Regional and country-specific patterns in deforestation relate to growth of cassava cropping area over 2005–2013. a represents regional patterns, showing province-level cassava area increase (ha) in Vietnam, Cambodia, and Lao PDR as related to degree of forest loss (ha) over a 2005–10, 2010–2013, and entire 2005–2013 time frame. b contrasts annual forest loss against increase in (harvested) cassava area, for 40 different Vietnamese provinces. Both variables are log-transformed, and only certain regression lines in b reflect statistically significant patterns (ANOVA, p < 0.05; see text for further statistics). Data are exclusively shown for provinces and time-periods in which cassava area expansion was recorded. Dashed lines represent patterns for 2005–10 (a) and 2009–10, 2010–11 (b)
