From 1990 to 2013, the notorious tiger poacher Kuttu Bahelia and his extended family – brothers, uncles, and their wives and children – reportedly killed hundreds of tigers and leopards in the tiger-rich Indian states of Maharashtra and Karnataka, according to law enforcement informants and media reports. “Even if half that [estimate] is correct, it is still a very significant number,” says Belinda Wright, who directs the non-profit Wildlife Protection Society of India (WPSI).

Whether or not we respond to climate change – and the security implications of that decision – is a major public policy question. But increasingly experts are paying closer attention to how we respond.

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.

At this year’s International Union for Conservation of Nature (IUCN) World Conservation Congress, more than 10,000 scientists, activists, and leaders from around the world committed to finding “nature-based solutions” to reversing environmental declines and securing a healthy, livable planet.

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.

A recent report by the UN Food and Agriculture Organization (FAO) warns that over the next 15 years, climate change will add to the number of people living in poverty via its effects on the agriculture and food sectors. By 2030, climate-related effects on food-related livelihoods could lead to an additional 35 to 122 million impoverished people, according to the 2016 State of Food and Agriculture Report.

An increasing number of conservation and health activists are beginning to understand the value of an integrated approach to development. Without addressing the needs of people, conservation measures will not be very effective, and conversely, without conservation, people lose vital natural resources and suffer consequences to their health.

Although separated by a thousand miles, the women of the Malaysian state of Sarawak and the Filipino island of Mindoro are united by a major struggle: climate change. As rainfall patterns grow increasingly unpredictable, natural disasters become more frequent, and drought ravages once-arable land, women are on the frontlines in both communities.
