Three Levers for Security

HL only

Resource security can improve through three distinct levers: reduce demand, increase reliable supply or change technology to reduce dependence.

Resource Demand lever Supply lever Technology lever
Food reduce loss and waste protect productive land or improve suitable yields storage and distribution systems
Water efficiency and leakage reduction recharge, reuse or diversified sources low-water processes or treatment
Energy conservation and efficiency diversify domestic low-carbon supply electrification, storage or substitution away from imports

If water exists but pipes leak and low-income households cannot access it, reducing losses and repairing distribution may improve security before a new reservoir.

Diagnose quantity, access, reliability and import dependence, then choose the lever that addresses the actual failure.

Increasing supply alone can induce more demand or leave affordability and distribution unchanged.
