With thousands of scientists representing 195 countries working for more than a quarter of a century, the Intergovernmental Panel on Climate Change (IPCC) is the world’s leading authority on of assessing climate change and its potential socio-economic impacts. However, Marc Levy, an IPCC lead author and deputy director of Columbia University’s Center for International Earth Science Information Network, says he’d have gone further in connecting climate change to conflict in their latest report if it were up to him.

How do we take actions today, how do we prepare for the future in such a way that we will achieve a more sustainable outcome?” [Video Below]

With the help of international aid, foreign land grabs in the Gambella region of Ethiopia have resulted in environmental degradation, more severe economic and social inequality, and human rights abuses, according to a new study by the Oakland Institute. We Say The Land Is Not Yours collects testimony from victims of “villagization,” a policy of forced displacement started under the military Derg dictatorship and, according to many, continued to this day under the guise of land investment.
