Urban Gun Violence
Today I stumbled across this compelling Associated Press story about how urban advocates have very mixed feelings about how the Newtown shootings have seemingly changed the national debate around gun control.
The moment also is causing some to reflect on the sudden change of heart. Why now? Why weren't we moved to act by the killing of so many other children, albeit one by one, in urban areas?
Certainly, Newtown is a special case, 6- and 7-year-olds riddled with bullets inside the sanctuary of a classroom. Even in a nation rife with violence, where there have been three other mass slayings since July and millions enjoy virtual killing via video games, the nature of this tragedy is shocking.
But still: "There's a lot of talk now about we have to protect our children. We have to protect all of our children, not just the ones living in the suburbs," said Tammerlin Drummond, a columnist for the Oakland Tribune.
In her column Monday, Drummond wrote about 7-year-old Heaven Sutton of Chicago, who was standing next to her mother selling candy when she was killed in the crossfire of a gang shootout. Also in Chicago, which has been plagued by a recent spike in gun violence: 6-year-old Aaliyah Shell was caught in a drive-by while standing on her front porch; and 13-year-old Tyquan Tyler was killed when a someone in a car shot into a group of youths outside a party.
Food for thought.

Prevent Deforestation and You Get Reforestation
Sometimes it is the studies with obvious sounding results that are the most helpful. A recent study of protected forest areas in Costa Rica examined levels of regrowth in those areas. Previously studies had really only assessed whether protecting areas prevented degradation. Happily, the study reveals that not only do you prevent deforestation and degradation by setting up protection areas, you also get some reforestation and improved forest health. Interestingly, the results did not vary by level or method of protection. Just setting aside the land made reforestation more likely. (Unless you are at a university or employer with access, you may have to pay for the article, which will appear in the next edition of Conservation Letters.) Abstract Below --
Global efforts to protect forest biodiversity and ecosystem services rely heavily on protected areas. Although these areas primarily aim to prevent losses from deforestation and degradation, they can also contribute to restoration. Previous evaluations of protected area impacts focus on avoided deforestation and fires. In contrast, we focus on the additional regrowth induced by Costa Rica's renowned system of parks and reserves. We use a quasi-experimental empirical design to control for confounding baseline characteristics that affect both regrowth and the assignment of protection. Between 1960 and 1997, an estimated 13.5% of previously unforested lands inside protected areas reforested because they were afforded protection. The level of additional regrowth does not vary by the strictness of protection. As in previous studies of protected area impacts on avoided deforestation, estimators that do not account for non-random assignment of protection can overstate protected areas’ impacts on regrowth by nearly double.

More than enough farmland?
Apparently, new studies are arguing that we have more than enough farmland worldwide to feed everyone. The conclusion then becomes that we can start converting some of that farmland to protected natural space. Perhaps it is because the study is assessing farmland worldwide (instead of considering its distribution), but these numbers seem hard to accept. (also unclear if the report fully considers climate change implications). If this assessment is correct, what should that mean for all the programs across the nation working to protect ag land?
by the way, the UN has reached a very different conclusion assessing the need for many millions of addition acres.
