Sand Scarcity

Sand Scarcity is the episode’s resource-economics case for scarcity that is not obvious because the material looks abundant. Sand heists and property rights in the Caribbean (Summer School) explains that sand has competing uses in beaches, resorts, concrete, glass, and land reclamation, while naturally useful sand is finite and can be extracted faster than it is replenished.

The concept matters because scarcity creates incentives for Illegal Sand Mining and Sand Theft Externality. Sand removed from one coast may become hotel frontage, construction input, or reclaimed land somewhere else, while the origin location bears erosion, ecological damage, and enforcement costs.

Key Claims

• Scarcity means competing valuable uses against a finite usable supply, not simply visual rarity.
• Sand demand connects tourism, construction, and national development projects.
• Hard-to-monitor beaches, rivers, and seabeds make enforcement costly.
• The Singapore land-reclamation example shows how demand in one place can physically reshape another place.

Connections

• Jamaica, Michael Hilton, Pascal Peduzzi, United Nations, and Singapore - source actors and cases.
• Illegal Sand Mining, Sand Theft Externality, Externality Internalization, and Tragedy of the Commons - adjacent concepts.
• Small-State Enforcement Capacity - policing constraint.
