In Koyra Number 6, a coastal hamlet bordering the Sundarbans in southwestern Bangladesh, a group of men unload barrels of water from their trawlers – 50 drums holding 30 liters each.

The Earth’s front-line defenders are disappearing at an astonishing rate. On average three environmental activists were killed each week in 2015, according to a recent report from the United Nations special rapporteur on the situation of human rights defenders. Global Witness, an international NGO that documents natural resource extraction, corruption, and violence, reports a 59 percent increase in deaths last year compared to 2014. In total, 185 killings of environmental defenders were recorded by Global Witness in 2015.

As global climate change affects livelihoods across the world, migration patterns are also changing.

Last month, headlines around the world heralded a breakthrough for international environmental cooperation. During ongoing ozone treaty negotiations in Rwanda, China broke with the developing world, agreeing with the United States to aggressively phase out hydrofluorocarbons, a significant global warming pollutant found in refrigerators and air conditioners. These changes are expected to make a big difference in combating climate change, mitigating half a Celsius degree of warming.

The palm oil sector is at a crossroads. Despite growing awareness of its massive effects on deforestation, the largely unregulated and decentralized industry has struggled to adopt, follow, and document rigorous sustainable sourcing standards.

 For island nations already dealing with more frequent and intense extreme weather events, climate change is an imposing burden. But many island states are responding and becoming “incubators of resilience,” as Lynae Bresser recently wrote.

It had been raining for two full days when the landslide came. Nirjala Adhikari vividly remembers the instant it hit her village in Sindhupalchok District, Nepal. “It was a very scary moment, and I couldn’t think of anything else than grabbing my mobile phone and my school certificate before I ran out of the house,” she recalled. “I secured my certificate because only this will help me establish a bright future.”
