A study released late last month by the Mexican Institute for Competitiveness, an elite think-tank based in Mexico City, asserted that proposals to legalize cannabis in Colorado, Washington and Oregon could cut Mexican drug cartels' earnings from traffic to the US by as much as 30%. The study, entitled "If Our Neighbors Legalize," drawing on previous research by the RAND Corporation, predicts that legalization in any US state would help drive down the price of high-quality domestic cannabis, undercutting the cheaper and less potent cartel imports. It calculated a loss of $1.425 billion to the cartels if Colorado legalized, $1.372 billion if Washington legalized, and $1.839 billion if Oregon voted yes. (AP, Nov. 1) In the Nov. 6 vote, initiatives calling for legalization of cannabis under regimes of state control were approved by voters in Colorado and Washington, but rejected in Oregon.

After nearly 10 years of struggle, Mexican campesinos fighting to protect their lands from the planned La Parota hydro-dam on the Río Papagayo won a definitive victory with the Aug. 16 signing of the "Cacahuatepec Accords" by Guerrero's Gov. Ángel Aguirre Rivero and the Council of Ejidos and Communities in Opposition to La Parota Dam (CECOP). Under  the agreement, Aguirre has committed the state not to approve La Parota dam if affected communities do not accept it, if they are not justly compensated, or it will impact the environment—effectively ending the project. Aguirre is also committed to seek an audience between CECOP and Mexican President Felipe Calderón to assure a commitment to the same principles from the federal government. La Parota dam would have flooded  17,000 hectares, impacting some 100,000 local residents.
