O QUE VOCÊ VAI VER NESTA AULA

Em 1968, o ecologista Garrett Hardin desenvolvia um estudo sobre superpopulação quando formulou um padrão de comportamento humano que explica uma problema que é conhecido como A TRAGÉDIA DOS COMUNS (ou Tragédia do Bem Comum). Na realidade, o problema foi descrito pela primeira vez pelo economista Willian Lloyd em 1833.

Basicamente este problema ocorre quando indivíduos agindo de forma independente e levando em conta somente seus próprios interesses exploram ao mesmo tempo um RECURSO COMUM e normalmente levam até a completa exaustão deste. 

Exemplo: pescadores que capturam peixes num lago, sem qualquer limite do quanto podem pescar individualmente, até a completa extinção dos peixes. Veja uma descrição do problema nesta animação em inglês com legendas em português.

Em 2009, a cientista social Elinor Ostrom da Universidade de Indiana (EUA), ganhou o Prêmio Nobel de Economia mostrando como comunidades desenvolvem estratégias de exploração de recursos comuns sem cair na "tragédia dos bens comuns", isto é, sem extinguir completamente os recursos. Veja esta entrevista dela ao programa Milênio.

Woodland caribou is a species at risk because of northward expansion of resource development activity.  Some herds are in dire condition and well below self-sustainability, while others are only moderately below self-sustaining levels.  Given limited conservation dollars, what are the most effective conservation actions, and how much money needs to be spent?  Which herds should be a priority for conservation efforts? The purpose of this model to provide insight into these difficult conservation questions.  

This model was developed by Rob Rempel and Jen Shuter at the Centre for Northern Forest Ecosystem Research, and was based in part on input from attendees of a modelling workshop ("Modelling the Caribou Questions") held at the 16th North American Caribou Workshop in Thunder Bay, Ontario, May 2016.
