A Stadium of Water, a Pitch of Land : What it actually takes to keep an elephant alive in Sri Lanka, measured against the ground ten thousand rugby fans could be standing on today.

Northampton Saints play the Asia Pacific Lions today at the Racecourse International Stadium in Colombo, a 10,000-capacity ground built for Sri Lanka's international rugby fixtures, in the first tour of the country by a major European club side in more than 140 years. That capacity is also a useful yardstick for something else: how much water and land a family of wild elephants needs just to survive in the dry zone, home to nearly all of Sri Lanka's wild elephants.

An adult elephant drinks about 189 litres a day, 378 of the 500ml Elephant House bottles sold in shops across the island, and that's before it wallows or bathes. Line up 378 people, hand each one a bottle, and have them empty it out for the elephant. That's one elephant, watered, for one day. Now picture the Racecourse International Stadium at full capacity doing the same thing: 10,000 bottles, 5,000 litres, enough for about 26 elephants for a day. A Sri Lankan family herd typically runs to 12 to 20 elephants, larger than elephant family groups elsewhere in Asia. That same stadium's worth of bottles would cover one of those herds for a day and a half at most.

Now space. A regulation rugby pitch runs to a bit over two acres. Twickenham's, where Saints beat Exeter Chiefs 26-17 in June to win this year's Premiership final, measures 125 by 70 metres, about 2.16 acres. The pitch at the Racecourse International Stadium isn't published to the metre, but as a ground built for Sri Lanka's official internationals it sits in the same size class. A female elephant herd's dry-season range in Sri Lanka runs to about 73 square kilometres, roughly 8,300 pitches that size, or 18,000 acres. Bulls range further, tracked across areas up to 346 square kilometres, about 39,500 pitches, 85,500 acres.

That much land isn't a preference. An elephant eats around 150 kilograms of vegetation a day, and a herd that stayed in one place would strip it bare within weeks. They move to let the ground recover, following food and water as both shift through the year. Radio-tracking work out of Yala found that most collared elephants crossed in and out of the park boundary routinely. Fence them inside a single reserve and they're cut off from the ground they need to survive on. Studies of elephant translocation in Sri Lanka reached the same conclusion from the other direction: moving problem elephants into protected areas didn't reduce conflict, because the areas were never large enough to hold them once they were prevented from ranging outward.

Sri Lanka's Ministry of Defence proposed in June 2025 lowering the threshold for issuing a firearm for crop protection from 5 acres of cultivated land to 2, opening up gun eligibility to far smaller farms. By July 2025, more than 13,000 firearms were already reportedly in farmers' hands for exactly that purpose, and only 5,000 of them were formally licensed. Shooting a wild elephant is still a criminal offence under the Fauna and Flora Protection Ordinance, carrying up to ten years in prison, but Agriculture Minister KD Lalkantha told Parliament in December 2024 that farmers faced no legal barriers to protecting their crops and could take "any action possible" against wildlife on their own land. An elephant moving between two parts of its own range now crosses a patchwork of two-acre plots instead of open forest, and a growing number of them are armed.

Sri Lanka's government announced this month that it's drafting a new national action plan for human-elephant conflict from scratch, rather than updating the one it already has, on the grounds that migration patterns have shifted since 2020. Sri Lankan elephants don't migrate across the island. Radio-collar data going back to 2008, the largest such dataset anywhere, shows what it always has: each elephant lives inside a fixed home range and uses the same routes within it year after year. When one turns up somewhere it isn't expected, that's usually because part of its range has been built over or fenced off, and it's looking for a way round what's left.

None of this works without water arriving when it's needed, and this year it might not. NOAA's Climate Prediction Center confirmed in August that El Niño is active and strengthening, with better than a 90% chance of a very strong event this autumn and winter, potentially the strongest since 1950. Yala is already dry enough that the Wildlife Conservation Department stepped in on 17 August to supplement water for wildlife there. Sri Lanka's elephants keep smaller ranges than their counterparts in India specifically because water in Sri Lanka is normally available year-round. Take the water away and that same mechanism runs in reverse, pushing herds further and into more contact with people.

Land like that doesn't come back once it's built over or cut off by a road, and a drought year is exactly when a herd most needs the option to move. The corridors linking one forest patch to the next are disappearing fastest in Sri Lanka right as El Niño makes them matter most. The government's own committee has "clearing elephant corridors" on its agenda this year. Whether that means clearing the encroachment blocking those corridors, or clearing the cover elephants use to move through them, hasn't been said.
