In drought-stricken Sri Lanka, farmers watch wells empty and wildlife crowd shrinking water holes - The Independent

What is happening to Sri Lanka’s farmers, water supplies, and wildlife during this drought?

Sri Lanka’s prolonged drought is disrupting the linked systems that support rural life. Farmers depend on seasonal rain, irrigation tanks, reservoirs, and groundwater. When these sources fail, crops die, household wells empty, and families need emergency water deliveries. Wildlife also loses drinking water and food. The crisis matters because farming provides both income and food for many communities.

In Medirigiriya, four months without rain destroyed rice, okra, and eggplant across Indika Nuwankumara’s 8-acre field. He is struggling to repay a $1,500 loan. Villagers with failed wells wait for government and charity trucks carrying water. In Yala National Park, elephants, deer, buffaloes, crocodiles, and birds gather around muddy pools, while workers refill some ponds with tankers and pipes.

Recent showers have helped some areas, but experts say scattered rain cannot quickly restore reservoirs or groundwater. Water rationing is already affecting many parts of the island. Farmers face continuing losses, while authorities must keep supplying people and wildlife until stronger rains return.

What is a drought, and how is it different from a normal short dry spell?

In general, a drought is a sustained period when rainfall is far below normal for a region and season. It becomes serious when the shortage reduces rivers, reservoirs, soil moisture, groundwater, and available water for people, farming, and ecosystems. A normal short dry spell may be expected between rainy periods and may not significantly reduce stored supplies.

Sri Lanka’s situation shows the difference. The country has been mired in drought for months, and the southwest monsoon brought little rain through late September. As the dry period continued, household wells failed, reservoirs stayed near one-third full, vegetable gardens withered, and rice fields produced losses. Wildlife ponds also dried, leaving animals around muddy pools.

The key issue is time and accumulation. A brief dry spell can end with the next shower. Months of limited rain can drain stored water faster than it is replaced. Recent showers have offered some relief, but experts say scattered rain will not restore Sri Lanka’s reservoirs and groundwater quickly. That is why rationing and water deliveries continue.

How severe is the water shortage, and how much rain and stored water has Sri Lanka lost?

The shortage is severe because both new rainfall and stored water have fallen short for months. Sri Lanka’s 74 reservoirs have hovered around one-third full, and many areas have introduced water rationing. Household wells have failed in affected villages, showing that groundwater has also been depleted. The article does not provide one national figure for the amount of rainfall or groundwater lost.

The southwest monsoon normally supplies up to 30% of Sri Lanka’s annual rainfall from roughly May through September. This year, however, there was little rainfall through late September. In Medirigiriya, four months without rain ruined crops and dried vegetable gardens. Across exposed tank beds, cattle searched for fodder, while residents waited for water trucks.

Recent showers have brought limited relief to parts of the island. They are not enough to refill reservoirs or restore groundwater after such a long dry period, according to climate experts. The continuing gap leaves farmers without reliable irrigation, households dependent on deliveries, and wildlife workers using tankers and underground pipes.

Why have Sri Lanka’s rains failed, and what roles might El Niño and human-caused climate change play?

Sri Lanka’s rains may have failed because several climate influences shifted normal weather patterns at once. The article identifies a strong El Niño as one likely factor. El Niño is a temporary warming of ocean waters that changes atmospheric circulation and rainfall patterns around the world. Higher temperatures, partly driven by human-caused climate change, have added heat stress and may worsen the drought’s effects.

The southwest monsoon normally brings up to 30% of Sri Lanka’s annual rainfall between roughly May and September. This year, little rain arrived through late September. Climate scientist Gayana Krishanthi Hendawitharana said scientists cannot say exactly whether climate change caused the event because more evidence is needed. She also noted that similar events are increasing in recent years.

This distinction matters. El Niño can help explain an individual season’s unusual weather, while climate change changes the background conditions over time. The article presents both as possible contributors, not as a proven single cause. Recent showers have helped some areas, but they cannot quickly repair the accumulated water deficit.

What happens to people, farming, food supplies, and wildlife when reservoirs, wells, and watering holes dry up?

Drying reservoirs, wells, and watering holes remove the basic water supplies that connect households, farms, food systems, and wildlife. People lose drinking water and must wait for deliveries. Farmers cannot irrigate crops, so food production and income fall together. Animals lose water for drinking and cooling, while drought also reduces the food available in forests. Heat makes every task harder.

In Medirigiriya, failed wells forced residents to line up with barrels, bottles, and jerrycans for free truck deliveries. Indika Nuwankumara lost rice, okra, and eggplant from his 8-acre field after four rainless months, leaving him struggling with a $1,500 loan. In Yala, deer lowered their heads toward muddy pools, while elephants stood beside shrinking watering holes.

The effects continue beyond the first crop failure. Water rationing spreads when reservoirs remain low, and families lose reliable food and earnings. Authorities are using tankers and underground pipes to refill some wildlife pools. Recent rain offers partial relief, but scattered showers cannot quickly restore the supplies on which people and animals depend.

How do Sri Lanka’s monsoons, irrigation tanks, reservoirs, and groundwater normally support rice farming?

Sri Lanka’s rice farming depends on seasonal water arriving at the right time. The country receives rain from two main monsoon systems. Rain fills irrigation tanks, and stored water is released through the cultivation seasons. Reservoirs provide larger stores for communities and agriculture. Groundwater, reached through wells, supplies households and can support local needs when surface water is unavailable.

Medirigiriya illustrates the normal cycle. During wetter years, rain fills irrigation tanks beside broad paddy fields. Water is then released as crops grow. This year, little monsoon rain left tanks and reservoirs low, while household wells failed. Exposed tank beds became dry ground, vegetable gardens withered, and an eight-acre rice and vegetable farm produced a major loss.

These sources work as a chain, so failure in one puts pressure on the others. Low reservoirs reduce irrigation, while continued pumping or dry conditions can exhaust groundwater. Sri Lanka’s reservoirs were around one-third full, and water rationing affected many areas. Until stronger rain replenishes storage and underground supplies, farming remains vulnerable.

How can warming ocean waters and a changing climate alter rainfall patterns and make extreme droughts or floods more likely?

Warming ocean waters can change air pressure, winds, cloud formation, and the paths of weather systems. El Niño is one example: the article describes it as temporary ocean warming that shifts weather patterns across the globe. If a monsoon’s usual rain-bearing conditions weaken or move, a region can experience a dry season instead of its expected rainfall.

A warmer climate adds another layer. Warmer air and land can increase evaporation and dry soils and water bodies more quickly. At the same time, warmer air can hold more moisture, so when rain-producing systems arrive, rainfall may come in heavier bursts. This can create a sharper contrast between dry periods and intense rain, rather than steady replenishment.

The article does not prove that climate change caused Sri Lanka’s drought. Its climate scientist says more evidence is needed, while noting that similar events are increasing. The immediate result is clear: low monsoon rainfall, higher heat, depleted storage, and stressed communities. Future planning must account for less reliable rainfall and stronger extremes.
