As the country’s complex conflict landscape continues to evolve and with the prospect of a political settlement on the horizon, ACLED established the Yemen Conflict Observatory, now called the Yemen Conflict Monitor (YCM), a platform offering an array of analytical tools and products to help users stay up-to-date with the latest developments.
The YCM is a living hub that combines data-driven analysis with robust qualitative assessments of political violence and disorder to enable greater awareness of how the status quo is shifting, complemented by providing a deeper contextual understanding of the conflict environment.
In 2022, the war in Yemen entered a new phase. Hostilities subsided after a six-month truce took effect in April and have remained limited despite the truce officially lapsing that October. Nonetheless, violence continues to take place across the country. Infighting among armed groups, flare-ups of tribal violence, and heightened repression have all contributed to sustained unrest. This ongoing violence demonstrates the multi-faceted nature of the conflict environment in Yemen, which continues to evolve. While ultimately bound to local developments rooted in the country’s turbulent history, these conflict dynamics have also become increasingly intertwined with regional and international factors.
With growing potential for a political agreement amid reports of progress in talks among officials in Sanaa and Saudi Arabia, widespread access to holistic and cross-cutting data-driven analysis is more necessary than ever to fill critical knowledge gaps. Even a comprehensive ceasefire between the Saudi government and the Houthis will be unlikely to address the multitude of tensions across the country, many of which precede the conflict that erupted in 2015. Yemen remains one of the world’s most complex and severe conflict environments, making timely and reliable information on violence patterns, drivers, and agents an imperative to inform realistic dialogue and negotiation at all levels, allow for conflict-sensitive and effective program design, and bolster accountability.
What is the YCM?
The YCM serves as a “living hub”: an online platform providing an array of analytical tools and products to help users keep up to date with the latest developments. The YCM combines data-driven analysis with robust qualitative assessments of political violence and disorder to enable greater awareness of how the security situation is evolving, complemented by providing a deeper contextual understanding of the conflict environment.
YCM outputs
The YCM includes an interactive map of Yemen, updated weekly, displaying incidents and fatalities over a set period of time, with a number of filters so that users can focus on areas of interest. It additionally features multiple monitors designed to track key thematic developments and connections with ACLED’s conflict forecasting and early warning tools to identify potential escalation hotspots across Yemen.
In addition, regular analysis of political violence in Yemen is provided in the form of monthly thematic reports summarizing recent conflict trends and developments, diving deeper into topics of interest and relevance, accompanied by an interactive timeline map highlighting key flashpoints. These are supported by a library of actor profiles, providing backgrounds on the composition, behavior, and agendas of key national and sub-national political, military, and security actors, as well as regional profiles. Actor and regional profiles are accompanied by interactive maps and territorial control maps.
The dashboard maps political violence events in Yemen and related events in Saudi Arabia since the onset of the regional conflict in March 2015. Data can be filtered by date and event type.
For further data exploration, see our interactive map covering Red Sea attacks. Regional profiles feature interactive maps showing events within each region, and actor profiles feature interactive maps showing events featuring each actor.
