Someone did the math recently. Seven million international visitors in 2025. Average stay, according to immigration entry-exit records, around seven nights. Divide by 365. At any given moment, roughly 135,000 foreign tourists are on the island. Bali's population is 4.4 million. That is about three percent.
The math is correct. The question is wrong.
∗ ∗ ∗Overtourism is a threshold concept. It assumes there is a point, a number, a ratio, after which tourism becomes damaging. Below the threshold: manageable. Above it: crisis. Officials say Bali has not crossed that line. Researchers say it has. Visitors form their own conclusions at six in the morning when the beach is empty and at four in the afternoon when it is not.
The threshold has never been agreed upon because it cannot be. There is no number at which a destination officially becomes overtouristed. The debate keeps running because arrival counts are not what is breaking.
∗ ∗ ∗Nusa Penida received more than 800,000 visitors in 2024. The island has a population of around 50,000. There is no public hospital. The road connecting the north to the south was not designed for the volume it now carries. Kelingking Beach, photographed by approximately every visitor who has ever stood at its clifftop, became so contested that a private developer built a 182-meter glass elevator to manage the descent. Construction began in June 2024. The cranes interrupted the view that tourists had come to photograph. It was ordered demolished in November 2025.
The photograph that made the cliff famous does not show cranes. It does not show demolition equipment either. The visitors keep arriving for the same image. The cliff looks the same in the photo. The island is not the photo.
At no point did Nusa Penida cross an overtourism threshold. The math still looks fine.
What the math does not reach is underground.
∗ ∗ ∗Over 65 percent of Bali's fresh water, according to researchers, is directed to tourism. Hotel rooms and villas consume an estimated 3,000 liters per day. The average tourist uses between 2,000 and 4,000 liters daily when pools, gardens, and resort facilities are included. A local resident in parts of rural Bali uses between 30 and 50. In parts of southern Bali during the dry season, the public water supply runs for a few hours a day. The hotels draw from the same aquifer around the clock.
More than half of Bali's 400 rivers have dried up. The island's freshwater aquifers have fallen to roughly 20 percent of their undisturbed state. Tourism water demand has grown several times over since the late 1980s. Visitor numbers since then have continued climbing.
The water table does not file a report. It just drops.
∗ ∗ ∗Every 35 days, the subak farmers gather at the water temple. Between 50 and 400 members, depending on the subak. Every farmer has an equal voice. Anyone who tries to pull rank is fined. They decide together when the water flows, when the fields flood, when they rest. Before any decision is made, offerings are placed at the shrine. Water, in Balinese philosophy, is not a resource. It is a gift, and the obligation to share it fairly is inseparable from the obligation to honor it.
This system has managed Bali's water for over a thousand years. UNESCO inscribed it as a World Heritage Site in 2012, calling it one of the most sophisticated cooperative water management systems ever devised. The committee noted, in the same inscription, that it was highly vulnerable to tourism pressure.
The hotels above Tegalalang are not at the meeting. They draw from the same water. Their pools do not observe the fallow cycle. Their spa treatments do not coordinate with the planting schedule. Increased extraction from above leaves less for the fields below. The farmers who maintain the landscape tourists come to photograph are in a water dispute with the tourism development surrounding them. That dispute does not appear in the arrival count.
∗ ∗ ∗Property prices in Denpasar rose 15.1 percent in the year to September 2024. Inflation ran at 3.5 percent. Ni Made Fitri Apriyani works in housekeeping at a tourist villa and earns between three and five million rupiah a month. Buying a home in the province where she was born is, in her own words, impossible.
∗ ∗ ∗Three percent sounds like an answer to the overtourism question. It does not explain why more than half the rivers are dry, or why the subak farmer is in a water dispute with the hotel above his field, or why the housekeeper cannot afford a home in her own city, or why a developer built a glass elevator on a protected cliff and then a governor had to order it torn down.
These are not problems waiting for a threshold. They are present now, in the ordinary week, in the systems that absorb the visit while the visit is happening.
Every 35 days, the farmers meet at the water temple. The agenda has not changed in a thousand years. They decide together when the water flows and when the fields rest. The hotels above them do not attend. The meeting continues.
