Global drought extent expands, but UN drought framework agreement stalls

Drought is increasingly affecting global land areas, with 2025 seeing 30% of land experiencing severe moisture deficit. Analysis indicates the spread of drought in 2025 was nearly three times that of the 1990s, with drought formation and impacts fundamentally changing. A clear link exists between global warming and frequent drought spells, with studies showing increased atmospheric evaporative demand intensifying drought severity.

Efforts to establish a global drought framework under the UN Convention to Combat Desertification (UNCCD) have stalled. Countries failed to agree on the framework at COP17, with some, including the US, arguing that drought is primarily a domestic or regional issue rather than a multilateral concern. Despite the lack of a formal agreement, drought has been designated a standalone agenda item for future COP sessions.

The proposed framework aimed to shift countries from reactive to proactive drought management, including early-warning systems and financial mobilization for drought resilience. UNCCD estimates an annual $278 billion gap in funding for land restoration and drought resilience efforts.
