GEOG 106 Lecture Notes - Lecture 10: Trawling, Overfishing, Food Security
Document Summary
Resources owned by everyone but no one in particular eg) atmosphere. Characteristics of cpr: excludability (control of access) If there is a open access to the resource, exclusion is difficult and joint use involves subtractability. Human extracts as much value as possible from common property resource in order to maximize individual well-being and over use the resource because they receive all the benefits but only small parts of drawback. 3 solutions for tragedy of commons : promoting a conscience among users, government regulation, privatization. Half of the fish populations are fully exploited. 1 quarter is over exploited and are in danger of extinction so that that 1 quarter can continue yielding without declining. Overfishing accelerated in controlled period of europe"s expansion. That are destroying the ecosystem logline fishing, trawling. By catch: accidentally capturing animals that were not targeted. Help improve food security by increasing amount of fish available.
