How a People Rises Together

Wangari Maathai was a biologist, the first woman in East or Central Africa to earn a doctorate, and a professor at the University of Nairobi, when she began listening to the rural women of Kenya describe their lives: streams drying, firewood further away each year, soil washing off the hills, children hungry. In 1977 she proposed something almost absurdly small. The women would plant trees. Not a government would; the women would, in their own villages, paid a few shillings for each seedling that survived. Many officials dismissed it. The Green Belt Movement grew anyway, from a handful of nurseries to a network that trained more than thirty thousand women and, by the time she died in 2011, had planted more than fifty million trees. Along the way it stopped a skyscraper being built in Nairobi’s Uhuru Park, got her beaten and jailed more than once, and in 2004 made her the first African woman to receive the Nobel Peace Prize. She liked to say that the movement had never been about trees. It was about people discovering that they could act, and then acting together.

One person can rise; I accept that now. But I have watched what happens next, and it is the part that breaks people. A young woman finishes her training, starts her business, and within a year her relatives have borrowed the capital, her neighbours have mocked her ambition, and the official who demands his payment has not changed. The person changed; the people around her did not. She is pulled back to where she started, and the lesson everyone draws is the old one: see, nothing changes. So answer this. How does change survive the people around it? And how does one person’s rising become a people’s rising, instead of a lonely exception that proves the rule?

Africa

You have described the most common way transformation fails, and you have described it correctly. A person who changes alone is surrounded by a norm that has not. Either the norm pulls the person back, or the person leaves. That is why the real unit of transformation is never the individual. It is the circle: the family, the street, the congregation, the ten people who meet every week. A person who changes inside a circle that is changing with them is not an exception. They are the beginning of a new normal.

Atlas

That is a claim. I want the mechanism.

Africa

The mechanism is this. People do not act mainly on what they privately believe. They act on what they believe the people around them believe and expect. A norm is not an opinion; it is a shared assumption about what others will do and approve. And the strange thing about norms is that they can be held in place by almost no one. If most people privately doubt a practice but each assumes the others support it, the practice continues, enforced by a majority that does not exist.

The clearest demonstration on my soil comes from Senegal. For generations, communities there practised the cutting of girls, and most families continued it not because they examined it but because they assumed every other family expected it: a girl who was not cut would not marry. In 1991 an organisation called Tostan began a three-year programme of education in villages, on health, human rights, literacy and the practical consequences of the practice. It did not tell communities what to decide. It gave them the facts and the time to discuss them together. In 1997 the village of Malicounda Bambara made a public declaration that it was abandoning the practice. Then it did something decisive: it reached out to the villages it intermarried with, because no single village could stop alone. Declarations spread, village by village, and by 2013 more than seven thousand communities in Senegal had publicly declared their abandonment of the practice. A UNICEF evaluation found that nearly ten years after the first declarations, the prevalence of cutting among girls in participating villages had fallen by more than half.

Why did the declaration matter? If people had already changed their minds, why not just stop?

Africa

Because stopping alone exposed a family to the very cost it feared. The declaration solved that. When villages that married into each other declared together, in public, before religious leaders and officials, each family knew what the others would do. The invisible majority became a visible one. That is the whole secret of changing a norm: not to persuade people one by one, but to let them see, together, what they already believe.

Atlas

And the honest limit? You promised me those.

Africa

Abandonment after a declaration is not complete. Tostan itself says so, and the evaluations confirm that the practice continues in some declaring communities. A declaration is not the end of a change. It is the moment a change becomes possible for everyone at once.

Atlas

Then let me push on numbers. How many people have to change before the rest follow? Is there a point where a minority becomes enough?

Africa

There is evidence for such a point, and it must be handled carefully. In 2018 the sociologist Damon Centola and his colleagues ran experiments in which online groups had settled on a naming convention, and a committed minority then tried to overturn it. Minorities below about a fifth of the group failed. Minorities of about a quarter or more succeeded, and the whole group switched. It is a striking result, but it comes from a simple, rewarded game, not from deeply held beliefs, and other researchers have found that for real behaviour the threshold can be far higher. So use it as a rule of thumb, never as a law: a committed quarter can change what a group sees as normal, and it does not need to convince everyone first.

Atlas

A committed quarter. Who are they?

Africa

In every community there are people others watch and copy: a respected teacher, an imam or pastor, a successful trader, a popular young voice, an elder whose word carries. Change that begins with them travels fastest, because others were already looking in their direction. A movement that wants to change a norm does not begin with the most hopeless. It begins with the most watched.

Atlas

You have used the word “together” in every answer. But there is something you have avoided. The circles my people already belong to are not new. They are mosques, churches, clans, age groups, savings associations, councils of elders. Some of them hold the old norms in place. Some of them are the very thing the modern world tells us to leave behind. Are they the obstacle, or the instrument?

Africa

Both, and the difference lies in what they are asked to carry. Those institutions are the soil of this continent. They hold trust where the state is weak, settle disputes where courts are slow, and give people a place where they are known. A transformation that ignores them stays on the surface, because it never reaches the place where people actually decide. A transformation that grows through them reaches the heart.

Think of the honeyguide, a wild bird found across much of my land. It leads honey hunters to bees’ nests and takes the wax when the nest is opened. In Mozambique, researchers found that the bird responds specifically to a particular call that the Yao hunters have passed down for generations: when the hunters used that call, the chance of being guided doubled, and the chance of being shown a nest rose more than threefold. Knowledge carried in tradition, confirmed by science, producing results neither could produce alone. That is what the old institutions can be: carriers of working knowledge, not relics.

Atlas

And when the tradition itself does harm? When the council of elders defends what should end?

Africa

Then the tradition must be judged by its purpose, which is what my ancestors always did. They changed their customs when the customs stopped protecting them. The test is simple and old: keep what protects life, dignity, unity, justice and the weak; renew what has lost its purpose; let go of what harms. The communities in Senegal did not abandon their tradition. They used its own deepest value, the protection of their daughters, to change one practice within it. That is how a people transforms without tearing itself apart: by letting its traditions become the judge of its traditions.

Atlas

So the circle is the unit, the norm is the mechanism, the committed and watched are the starting point, and the old institutions are the soil. Is that what you are telling me?

Africa

That is what the evidence tells both of us. And you will notice that none of it requires a government. All of it can begin this year, in any community, with ten people who decide to meet. But circles do not build roads, run hospitals or keep money honest. For that, a people needs builders inside its institutions. That is where we go next.
