Central question

Which authority must act when a rainfall forecast changes the risks to water supply, sanitation, storage, drainage or access?

The answer depends on where rain is expected, the condition of local infrastructure, national and county mandates, and whether money reaches the responsible service before harm occurs.

Coverage

The decisions in view

  1. 01

    Seasonal and short-range rainfall evidence, including uncertainty and local variation.

  2. 02

    Water-resource, sanitation, drainage and storage decisions across national and subnational systems.

  3. 03

    Consequences for health, livestock, food systems, settlements, infrastructure and household expenditure.

Current assessment

A wetter outlook does not settle the water question

The national outlook does not determine local water availability or establish that public measures have been completed. Drainage, safe water, storage, infrastructure continuity and preparedness finance require county-specific evidence.

Food, electricity and the household cost of climate action

Studies published from 7 to 13 October examine wheat losses, wetland farming, electricity peaks, unequal household costs and flood-insurance access. The analysis connects those findings with Kenya’s food imports and water rules, and South Africa’s proposed power procurement.
