The concept of soil security has strategic value in that it can serve to
focus and guide the development of policies addressing the six global existential
challenges, such that interventions for one challenge result in favourable effects on
other challenges. Soil security arises from both top-down (global challenge) and
bottom-up (societal value) considerations. We envision it as a homologous concept
to those of food and water security. The major goal is to measure and manage the
fi ve dimensions of capability, condition, capital, connectivity and codifi cation.
