In an era where water scarcity and disputes over water rights increasingly shape global politics, understanding the nexus between water and peace is more critical than ever. Recent events such as the border clashes between Kyrgyzstan and Tajikistan, or continued tensions between Egypt, Ethiopia, and Sudan over the Nile River’s usage, underscore the urgent need for comprehensive strategies to address both the hydrological and social dimensions of water management.

Land is crucial to people’s livelihoods, health and wellbeing, culture and identity. So disputes over access to or use of land are a prominent feature in many conflicts. The Environmental Justice Atlas finds that land is at the root of conflict dynamics in approximately a third of environmentally-driven cases recorded. And because land is increasingly under threat—20-40% of global land area is degraded—the risk of conflict is increasing.

As relations between the United States and China become increasingly acrimonious, reducing methane emissions from oil and gas operations remains an exceptional arena where respectful engagement between both countries endures.

Methane is a highly-intensive, short-lived climate pollutant, and it is responsible for about 30 percent of current global warming. Two-fifths of the global total of human-caused methane derives from fossil fuel production, including oil and gas. And the U.S. and China play an outsized role. The US leads the world in oil and gas production and sectoral methane emissions, while China ranks in the top five producers. China is also the global leader in total methane releases, including agriculture, livestock, coal production, and waste emissions.

When Luxembourg’s Green Party was offered the defense portfolio in coalition talks after performing strongly in the country’s 2019 elections, its senior members faced a dilemma. Never before had a party of its political stripe held that brief anywhere in the world.

Some of the Green rank and file, drawn from pacifist backgrounds, seemed uncertain as to what to make of it all. But to François Bausch, the Green politician who ultimately took on the roles of defense minister and deputy prime minister there, the answer seemed obvious. Here was an opportunity for the party to advocate for climate security from a highly relevant perch, all while showing voters that it could be trusted with such strategic concerns.

The promise of global connectivity to enhance developing countries’ well-being is a reality as more citizens go online and international donors and their partners improve their digital service delivery. This surge can spur economic growth, advance freedom, boost transparency, increase accountability, strengthen civil society, and empower women.

The recent floods and landslides in Brazil, displacing almost 100,000 and killing at least 100, reminds us that climate change-fueled extreme weather, combined with an intense El Niño, is a deadly combination. Governor Eduardo Leite of the southern Brazilian province, Rio Grande du Sol, described the devastation the region was subjected to as “unprecedented.” As President Luiz Inacio Lula da Silva noted: “We need to stop running behind disasters. We need to see in advance what calamities might happen and we need to work.”

Human-produced pollution is the single leading cause of mortality today, yet it is not widely considered a form of violence. On July 28, 2022, the United Nations General Assembly (UNGA) voted—with 161 in favor and eight abstentions—that living in a clean, healthy, and sustainable environment is a human right. Building on a similar declaration by the United Nations Human Rights Council in October 2021, the UNGA has now reinforced the notion that the growing assaults on human health through environmental hazards are transgressions against the basic rights and freedoms of people. Efforts to create a human right to a healthy planet, and even a planetary right to health that would signifying potential rights of nature, are growing both in real activity and demand.

The potential threat climate change poses to peace and security is perhaps nowhere more apparent than in the Middle East and North Africa (MENA). Nationally Determined Contributions (NDCs) are one way MENA countries can address this compound risk.
