Event timeline (Source DFS)

Humanitarian access severity levels are estimated using NRC’s Hard-to-Reach (H2R) methodology. All ratings mainly depend on available open-source data and information provided by the humanitarian and the conflict-analysis community, corroborated with key informant interviews, then reviewed and validated by operational analysts.

Oblasts, raions and cities color fills are based on an aggregation of both the estimated level of access by affected populations to assistance and the estimated level of access of relief actors (international, national) to affected populations.


Detailed constraints color fills - aiming at showing the main access-related barriers - should be used with caution at this stage due to inconsistent information flows, especially in hard-to-reach areas.

Ratings do not represent the diversity of operating relief actors and their respective levels of access to populations. Additionally, due to the limited available information and confidentiality issue, the outreach by local CSOs and Ukrainian volunteer networks is not represented at its full extent.

Ratings assume that relief actors are registered and comply with the administrative requirements of official/de facto authorities controlling the area (i.e: DNR accreditations in Donetsk NGCA).
