As world leaders gather in Azerbaijan for COP29, the UN-led annual climate negotiations, critical decisions will be made about the future direction of global climate action, including what to prioritize, how to fund it and how to deliver it. It would be a failure to reinforce the existing imbalances between stable and fragile communities that intensify injustices and leave climate-vulnerable, conflict-affected communities unsupported in the face of compounding crises.

Just as the impacts of climate change are not experienced equally among countries, the impacts are spread unevenly within countries as well. For instance, climate shocks like droughts and flooding can damage the livelihoods and economic security of rural and pastoralist communities, which can overlap with existing political, economic and societal marginalization as seen in places like the Central Sahel.

The field of view (FOV, also called angle of view) is the width of the scene that a camera detects on its sensor. It is determined by the focal length of the lens in relation to the sensor size. Longer lenses or smaller sensors produce narrower fields of view, while shorter lenses or larger sensors produce wider fields of view. A smaller field of view means that a camera is more “zoomed in” (to use a term that most people are familiar with). For example, a camera with a 90° horizontal field of view (HFOV) will see a 1000m wide section of a wall that is 500m in front of it. If you then adjust that camera’s HFOV to only 1°, it will fill the screen with an 8.7m wide portion of that same wall. This second “zoomed in” field of view is what customers are looking for when they want a camera that can see a long distance. They want a narrow field of view.

November 11, 2024 —  As world leaders gather in Baku for COP29, the International Rescue Committee (IRC) is calling for immediate, bold and decisive action to address the devastating impacts of climate change on conflict-affected communities.

The IRC identifies 17 countries^ at the epicenter of climate vulnerability and conflict. Those countries are home to just 10.5% of the global population and 3.5% of annual greenhouse gas emissions, but one-third of all people affected by natural disasters and 71% of those in humanitarian need globally. This convergence is reinforced by the compounding impact of climate change, a threat multiplier for vulnerable communities by deepening food insecurity, threatening livelihoods and inflaming community tensions.

“The failure to make climate action work for climate-vulnerable, conflict-affected communities is one of the biggest climate injustices COP29 needs to address, said Ken Sofer, Director of Public Advocacy at IRC. “These communities are the least responsible for the climate crisis, the most impacted, and the least supported by the status quo approach to climate action. COP29 offers a critical opportunity to turn words into action and ensure that the most vulnerable communities receive the resources and support they need to break the toxic feedback loop of climate vulnerability and conflict. There are evidence-based solutions like anticipatory cash and seed security strengthening that can limit the harm of the climate crisis even amidst conflict. The question for global leaders at COP29 is whether they’re willing to break from an unjust status quo and make climate action work for people living at the epicenter of the crisis.”
