Correction to Supporting Information for Suweis et al., Resilience and reactivity of global food security
See original article:
- Resilience and reactivity of global food security - May 11, 2015

ENVIRONMENTAL SCIENCES Correction to Supporting Information for “Resilience and reactivity of global food security,” by Samir Suweis, Joel A. Carr, Amos Maritan, Andrea Rinaldo, and Paolo D’Odorico, which appeared in issue 22, June 2, 2015, of Proc Natl Acad Sci USA (112:6902–6907; first published May 11, 2015; 10.1073/pnas.1507366112).
The authors note that Figs. S2 and S3 appeared incorrectly, and that the legends for Figs. S2, S4, S7, S10, and S11 appeared incorrectly. The SI has been corrected online.
Probability density function (PDF) of the reactivity λH of the nations belonging to the four groups for four different years.
Map of unstable countries (i.e., λ > 0, in red) on three different years: 1987 (Left), 1997 (Center), and 2009 (Right).
Group A nations (x ≈ KL > KT): net exporters and their exports substantially reduce the resources available to their populations.
Group B nations (x ≈ KT > KL) exhibit an interdependency between demographic growth and food imports. These countries cannot sustain their population relying only on their local resources.
Group C nations (x ≥ KL ≈ KT): countries where food trade does not have a substantial impact on food availability.
Group D: countries that are affected by an overall food deficit.
