origin and arrives at a destination.
Pareto Optimal (Economics) A theoretical state where the distribution of resources
is such that it is impossible to reallocate resources benefit one individual without
being detrimental to one or more other individuals.
PCII (Data) A government-enforced national security categorization originating
after the September 11th, 2001 attacks in the USA, such that some food energy
or water infrastructure data concerns security-critical protected critical infrastructure information.
Pedolith A soil structure which has been impacted by biogeochemical processes
have added, removed, or changed its components.
Pee-Cycling The conversion of human liquid waste (urine) to sterilized nutrientrich fertilizer that can be re-used for agricultural and ecological purposes.
Peri-urban Areas immediately surrounding a city that have mixed urban and rural
characteristics.
Petroleum A blend of hydrocarbon liquids that can be separated into a variety of
valuable products through distillation.
Petrostate A nation whose economy is highly dependent on the production and
sale of petroleum.
PII (Data) A categorization as personally identifiable information that is covered

Planetary Boundary(ies) A concept used to define a ‘safe operating space for
humanity’ by defining science-based limits on environmental impacts at the
planetary scale, beyond which society might be negatively affected.
Pluralist Model of Government A model of government in which no single set of
interests in the society has sufficient power to influence governmental action to
a significant extent. Organizations and processes of government determine the
public good and act accordingly.

Pollutant Discharge The discharge of a chemical, sediment, or other material that
reduces the quality of the receiving water body.
Position Something that a person or group has decided on. See also interests.
Positive Behavioral Models Models of behavior people actually do exhibit in a
particular scenario, regardless of the behavior that a specific model predicts. (See
Normative Behavioral Models.)
