In time of accelerated rate of climate change, relevant concept for human welfare is ensuring that net deficits in dietary intake are avoided. Particularly at an early age.
Sustainable livelihood systems require adequate net dietary intake. Means availability of clean non-contaminated drinking water, control of water and insect borne diseases, avoiding capability poverty (undeveloped brain circuitry due to stunting) at early age, and balanced dietary intake.
Sustainable food security- as apparently argued by FAO - represents an inferior reductionist concept.
