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.
