East African Schools Face Rising Costs of Preparing for Extreme Weather

Tanzania has brought forward the closure of pre-primary, primary and secondary schools on the Mainland by three weeks, a decision that shows how weather risk can quickly become an education and public-finance problem. Schools will now close on November 13 rather than December 4 after forecasts warned of potentially heavy rains between October and December.

The move is not simply about losing teaching days. Tanzania has also brought forward several national assessments and examinations because flooding and transport disruption could prevent pupils, teachers and examination supervisors from reaching centres safely.

Where does the cost appear?

The first cost is physical damage. Flooding can damage classrooms, laboratories, furniture, books, electrical equipment and sanitation facilities. Heavy rain can also make roads impassable, preventing teachers and pupils from reaching schools even when buildings remain intact.

The second cost is interruption. A closure means teachers cannot deliver lessons and families may have to keep children at home. For households that depend on daily work, childcare disruptions can have an economic effect that does not appear in an education budget.

Tanzania's current timetable changes show the scale of the logistical problem. The Ministry of Education moved the Standard Four national assessment to October 5 and 6 from October 21 and 22, while the Standard Two assessment moved to October 7 and 8 from November 17 and 18.

Why resilience can be cheaper

Resilience does not necessarily mean expensive new buildings. It can include better drainage, raised electrical installations, stronger roofs, rainwater harvesting, safe access routes and maintenance systems that identify defects before they become failures.

The economics depend on the location and hazard. A school in a flood-prone area needs a different design response from one facing drought or extreme heat. That is why infrastructure planning should begin with local risk rather than a single national template.

The current Tanzanian case also shows why planning data matters. The government said 21,353 schools are involved in the Standard Two assessment and 21,008 in the Standard Four assessment. When weather disrupts transport or power across a large network, the cost of contingency planning rises rapidly.

What should governments measure?

A useful resilience budget should track more than the number of classrooms built. It should ask how many schools are exposed to flood risk, how often closures occur, how much emergency repair costs, how long damaged facilities remain out of service and whether new projects are designed for the hazards expected in their locations.

Procurement also matters. A cheaper project can become more expensive over its lifetime if materials, drainage or foundations are poorly suited to local conditions. Conversely, a modest upfront investment in water management or structural protection can reduce repeated repair bills.

This is an area where better data can improve spending. Education authorities, meteorological agencies, local governments and infrastructure planners can combine weather records with school asset registers to identify the sites where resilience investment is likely to produce the largest benefit.

What happens if governments wait?

Reactive spending will remain necessary because extreme weather cannot be eliminated. But relying mainly on emergency response can leave education systems permanently behind the next disruption. Repairs compete for funds with new classrooms, teacher recruitment and learning materials.

Tanzania's decision also illustrates why early action can have an economic value. The government is trying to reduce the probability that examinations, transport and school operations fail at the same time. That may shift some costs forward, such as rescheduling assessments and preparing schools, but it can reduce the disruption caused by a severe weather event.

The wider economic argument is about protecting the value of public investment. A school is not only a building. It is a service used by children, teachers and communities. When weather repeatedly interrupts that service, the cost is borne across the education system and household economy.

East Africa's climate risks will differ by country and locality, so resilience spending should be targeted rather than uniform. The immediate policy choice is not whether governments should spend more on climate. It is whether part of the money already allocated to education infrastructure can be used in ways that reduce the cost of the next disruption.
