The time to repair the roof is when the sun is shining

Prudence in Fair Weather

On 29 October 1999 a super cyclone struck the Odisha coast and killed nearly ten thousand people. Fourteen years later, in October 2013, Cyclone Phailin hit the same coast with comparable fury, yet the deaths were counted in dozens, because close to a million people had been moved to shelters in time. In 2019 Cyclone Fani, the strongest storm to reach the state since 1999, again claimed few lives for its size. The sky had not grown kinder. Odisha had used the calm years between storms to build cyclone shelters, train volunteers and sharpen its warnings. That is the wisdom of the line John F. Kennedy offered in his State of the Union address of 1962: the time to repair the roof is when the sun is shining. Preparation is cheapest and wisest in good times, and the real test of a person, an economy or a nation is not how it behaves in the storm but what it did before the clouds gathered.

The metaphor is plain and its logic hard to fault. In the rain one cannot safely climb onto a wet roof; the leak has already soaked the house, materials are scarce and every hand is busy with buckets. When the sun shines, the work is safe, cheap and unhurried, but nothing feels urgent. Here lies the paradox: we feel the need for repair only when it is too late to repair well. Behavioural economists call this present bias, the tendency to overvalue today's comfort against tomorrow's safety, and it explains why good times so often breed complacency rather than preparation. The maxim therefore asks for a discipline that runs against instinct: to act on a danger one cannot yet see.

Civilisations learnt this early. In the Book of Genesis, Joseph advised Pharaoh to store grain through seven years of plenty against seven years of famine, and Egypt survived. Aesop's ant gathered food through the summer while the grasshopper sang. Kautilya's Arthashastra treats the kosha, the treasury, as the root of the state's strength and expects the king to keep stores of grain and wealth against calamity. Indian communities built stepwells and village tanks so that the monsoon could be captured when it came; Chand Baori at Abhaneri in Rajasthan still stands as a monument to that foresight. Each tradition treats prudence not as timidity but as care for one's future self and for those who come after.

For the individual the lesson is intimate. Health is a roof best repaired while one is well: exercise, sleep and screening cost little at thirty and save a great deal at sixty. Savings work the same way, because an emergency fund built in a year of steady salary is what keeps a family out of debt when a job is lost or a parent falls ill. Skills must be learnt while one is employed, not after a new technology has made one's work obsolete. Friendships and family bonds need tending in calm seasons so that they hold in a crisis. A student who revises steadily through the year meets the examination as a review; one who waits for the final month meets it as a storm.

Moreover, the principle lies at the heart of sound economic policy. John Maynard Keynes argued that governments should spend in a slump, and the corollary is that they must save in a boom, a discipline economists call counter-cyclical policy. India learnt the price of an unrepaired roof in 1991, when its foreign exchange reserves fell to barely a few weeks of imports and the country had to pledge its gold abroad. It learnt the reward of repair later: reserves built up through calmer years crossed 700 billion dollars in 2024 and gave the economy a cushion against global shocks. The Fiscal Responsibility and Budget Management Act, 2003 sought to make the same habit law, and Norway's sovereign wealth fund, which saves oil revenue for future generations, shows how far a nation can carry it. Banks are now required to build capital buffers in good years, a lesson written in the twin balance-sheet problem of the 2010s, when loans made in a boom turned bad in the bust that followed.

India's demographic dividend is itself a season of sunshine. The Economic Survey 2018-19 projected that the share of the working-age population would peak around 2041, after which the country will begin to age. The years before that peak are the time to invest in schooling, nutrition, health and skills, so that a large young workforce becomes a productive one. A country that spends its youthful decades without building human capital will grow old before it grows rich, and the window will not reopen.

The same logic governs disasters and pandemics. Odisha's turnaround was built in quiet years, and India has given it institutional shape through the Disaster Management Act, 2005, the National Disaster Management Authority and the National Disaster Response Force. The Sendai Framework for Disaster Risk Reduction (2015-2030) puts reducing risk before responding to it, and the Coalition for Disaster Resilient Infrastructure, launched by India in 2019, carries the idea abroad. The COVID-19 pandemic was the costliest lesson of all. In 2015 Bill Gates warned that the world was not ready for the next outbreak, and in 2020 many countries were still caught without enough beds, oxygen or testing capacity. Climate change is the largest roof of all: the Stern Review of 2006 estimated that unchecked warming could cost at least five per cent of global GDP every year, against about one per cent a year for acting early. Every year of delay makes the repair dearer.

Water and security follow the same rule. The Jal Shakti Abhiyan's "Catch the Rain" campaign, launched in 2021, asks communities to desilt tanks and build recharge pits before the monsoon arrives, because a dry March is the only time a pond can be cleaned. India's strategic petroleum reserves at Visakhapatnam, Mangaluru and Padur are a roof built against an oil shock. In defence, the Kargil Review Committee chaired by K. Subrahmanyam found that gaps in intelligence and surveillance had been left unattended in quieter years, and its recommendations reshaped the security apparatus. A nation's peacetime choices decide the price it pays in war.

Yet the advice is easier to admire than to follow, and the obstacles deserve honest treatment. Electoral cycles reward the visible ribbon-cutting over invisible prevention; no one wins votes for the flood that did not happen. The economist Hyman Minsky argued that stability is destabilising, because calm years encourage the risk-taking that produces the next crisis. Good times also bring competing claims: a poor household or a developing country may fairly ask how it can save for tomorrow when today's needs are pressing. And not every storm can be foreseen. Prudence can harden into paralysis, as when excessive caution hoards money that could have built schools or roads. The maxim does not ask us to fear the sun, only to set aside a sensible share of fair-weather gains for repair.

The way through is to turn foresight from an act of individual virtue into a habit of institutions. Rules can do what willpower cannot: fiscal rules that bind governments to save in booms, building codes enforced before earthquakes, protected maintenance budgets for bridges and dams, insurance that prices risk honestly, and early warning systems tested in drills rather than in disasters. The collapse of the Morbi suspension bridge in Gujarat in October 2022, which killed more than 130 people days after it reopened, showed what follows when repair is done in haste and oversight is skipped. Japan, which trains its children in earthquake drills from their first years of school, shows that preparedness can become culture. When prudence is written into routine, it no longer depends on someone remembering the rain on a sunny day.

In the end the maxim is a lesson in humility. Sunshine is never permanent, and the wise do not mistake a good season for a safe one. Odisha's shelters, India's reserves, a family's savings and a student's steady revision rest on the same quiet decision to do the hard work while it is still easy. The storm will come for every person and every nation; what decides the damage is whether the roof was mended while the sun still shone.
