GALGAMUWA, Sri Lanka – Residents in Galgamuwa, a rural village in Sri Lanka’s North Western Province are mourning the death of an iconic wild, bull elephant that roamed the area. While Galgamuwa is on the frontlines of one of Sri Lanka’s worst human-elephant conflicts, people had a soft spot for this tusker, popularly known as Kavantissa. Named after a king who ruled the Kingdom of Ruhuna in ancient Sri Lanka in the 3rd and 2nd centuries B.C.E, Kavantissa was known for its gentle nature. Galgamuwa residents say it never attacked a human in its lifetime. Rathnayake Mudiyanselage Jayathilaka Bandara is a resident in Galgamuwa and an ardent animal lover. Bandara and another local resident named Kumara dedicated their time and effort to protect Kavantissa and the large herd of elephants (Elephas maximus maximus) that became famous for crossing the railway tracks in Kasikote, a town located between Galgamuwa and Ambanpola in the north west. Soon, this crossing became a must see among elephant lovers and Kavantissa would often emerge at the tail end. Bandara tells Mongabay that the demise of Kavantissa is heartbreaking because the iconic tusker was gentle and disciplined. He recalls how Kavantissa would patiently wait for the herd of elephants to cross the railway line before it made its dramatic appearance. “Sometimes it would pause before crossing the road and journey toward the nearby Palukadawala tank,” he said. “Perhaps that was its way of greeting me and Kumara. Kavantissa would sometimes push the electric fence obstructing its…This article was originally published on Mongabay

COLOMBO — Fathima Rinoza lives on the fourth floor of a 14-story apartment block in Dematagoda, a suburb of Sri Lanka’s commercial capital, Colombo. She rarely keeps the two windows in her house open for long. The heat becomes unbearable by midday, she says, and the surrounding buildings obstruct wind flowing in the direction of her home. In addition, the stench from littered surroundings discourages residents like Rinoza from keeping their windows open. “Fresh air is a luxury for us because we can’t keep windows open for too long. By noon the heat becomes unbearable. If I keep the windows open till evening, there’ll be a lot of dust inside the house,” she tells Mongabay. Rinoza keeps the two fans in her house working almost the entire day to cool the house. The heat and poor ventilation make people like Rinoza who live in cramped urban settings heavily dependent on mechanical or active-cooling methods such as fans and air conditioners. According to the International Energy Agency (IEA), the urban residential sector accounts for nearly a third of Sri Lanka’s total energy consumption: to heat and cool buildings, and to run lights, devices, and appliances. As heat and energy demand rise, Sri Lanka is actively exploring the adoption of traditional and modern passive-cooling methods, primarily in the residential sector. Passive-cooling strategies In passive cooling, the building design approach uses natural energy flows like wind and shade to lower indoor temperatures. Research by Sri Lankan engineers in 2021 on natural ventilation for…This article was originally published on Mongabay
