The report aims to complement IPC analyses and facilitate early recognition and coordinated responses to emerging major food and nutrition security crises among humanitarian and development stakeholders. 

This report assesses the current and anticipated global humanitarian impacts of the conflict between US–Israel and Iran. It examines how the severity of the shocks transmitted through energy and fertiliser markets, trade routes, financial flows, humanitarian logistics, and regional political instability intersect with existing humanitarian needs and limited coping capacity.

This Spotlight on Social Impact in Yemen (SoSI) report follows previous social impact studies (formerly referred to as Social Impact Monitoring Project reports).

On 28 March, the DFA launched a ballistic missile towards central Israel, marking their first reported attack since the onset of the conflict involving the US, Israel, and Iran. The Houthis stated that they would continue to conduct unspecified operations until the US and Israel cease military actions against Iran and its allies in the region

This report uses descriptive, explanatory, and anticipatory analysis to help decision makers understand the scale of the ripple effects from the war, dividing the impacts into four themes:

- energy and water security

- economy, shipping disruption, and food security

- conflict and social cohesion

- humanitarian needs, gaps, and access.

Food security in Yemen remains dire. In December 2025, 64% of households were unable to meet minimum food needs, with severe food deprivation affecting 37% of the population nationwide and higher prevalence in the Government of Yemen (GoY)-controlled areas of Ma’rib (55%), Ad Dali’ (48%), and Abyan (45%) and the Ansar Allah (AA)-controlled areas of Al Bayda (46%) and Al Jawf (44%).

Between June–November 2025, crisis-affected populations in 36 countries experienced high to extreme humanitarian access constraints, according to the ACAPS humanitarian access analysis framework. Operational barriers, including the requirement for aid organisations to secure multiple sequential approvals, fragmented service coverage across jurisdictions, and increased reliance on remote modalities, further hindered their ability to meet basic needs.

This briefing note explores TFGBV in Yemen, seeking to identify how TFGBV is perpetrated, analyse its impact on survivors, and explore how women and girls navigate these challenges within a society characterised by traditional gender roles and a strong emphasis on ‘honour’. This report also identifies information gaps that require further investigation for a better understanding of TFGBV in Yemen.
