Is historically arid Beijing ready for a wetter future?
"In the past, they closed scenic areas and campsites, evacuated tourists and relocated villagers. If you warn people in time, good, but if not, it's a natural disaster," said Cui, whose 10 properties in the same Huairou district village, which he had spent 35 million yuan ($4.87 million) renovating, were submerged.The floods exposed weaknesses in the rural emergency response infrastructure for Beijing, whose urban core is surrounded by several rural districts.But they also revealed how historically-dry Beijing, home to 22 million people, remains insufficiently prepared for what experts say will be an increasingly wet future. The Chinese capital has experienced three deluges since 2012 that forecasters said could only happen once every 100 years, and climate experts warn there is a growing risk of disasters on a previously unthinkable scale.Chinese experts are increasingly calling for city planners to prioritise "ecological resilience" given the disastrous effects of climatechange."The current understanding of the climate crisis and its future challenges is insufficient, which naturally leads to insufficient deployment and planning," said Zhou Jinfeng, Secretary-General of the China Biodiversity Conservation and Green Development Foundation.

China's ministries of housing and environment, and the Beijing city government, did not respond to faxed requests for comment.While two Beijing districts devastated by floods in 2023 have issued long-term reconstruction plans prioritising "climate-adaptive city construction" and proposing measures to improve rural flood control systems and upgrade infrastructure, the vast majority of recently-commissioned infrastructure projects in the capital do not prioritise climate adaptation in their plans.A Chinese government database showed only three Beijing infrastructure projects in the past five years whose procurement tenders mentioned "ecological resilience", while several hundred tenders mentioning "climate change" were mostly related to research projects at state scientific institutes in Beijing.advertisementEcological resilience refers to measures such as restoring natural river embankments, reducing the use of concrete and other hard materials and excessive artificial landscaping, as well as increasing biodiversity, according to Zhou.In a shift away from decades of breakneck urbanisation that propelled China's economic growth, a top-level urban planning meeting in July emphasised building "liveable, sustainable and resilient" cities.Mid-July is typically when northern China's rainy season starts, but this year it had its earliest start since records began in 1961, while several Beijing rivers experienced their largest-ever recorded floods.Citywide rainfall in June and July surged 75% from a year earlier, official data showed.This is due to the "significant northward expansion of China's rain belt since 2011" linked to climate change, the director of China's National Climate Center told state-owned China Newsweek, marking a shift towards "multiple, long-term, sustained cycles of rainfall" in the traditionally arid north.'SPONGE CITIES'China's policymakers have taken some steps to combat urban flooding.

Landslide buries buildings outside Guineas capital, killing 11 and injuring 10
Last Updated: Conakry (Guinea), Aug 21 (AP) Part of a mountain gave way due to heavy rains outside the capital of Guinea, sending a landslide onto buildings in a rural community and killing at least 11 people, authorities said Thursday. Another 10 people were seriously injured and the death toll was expected to rise. The landslide occurred Wednesday night in Maneah, a rural commune in the Coyah Prefecture located 50 kilometers (31 miles) from the capital Conakry, according to a statement by the National Agency for Emergency Management. 'Last night, it was around 7 pm. It was raining, and suddenly I saw the mountain come off. It fell on the houses at the foot of the mountain. The mud buried the houses. No survivors came out alive," said Kone Pepe, a local resident. Search and rescue operations were continuing late Thursday. 'It's a part of the mountain that gave way under the effect of the rain and spilled onto the buildings," said Mory Condé, minister of urban planning and housing, during a visit to the site. The collapse followed heavy rains in the area and comes as West Africa has experienced record flooding, killing over 1,000 people last year and displacing hundreds of thousands across the region.

Puerto Ricos schools unequipped to cope with ever hotter heat waves
Agency: PTI Culebra (Puerto Rico), Aug 21 (AP) When temperatures soar at a public school on the small Puerto Rican island of Culebra, students scatter in search of relief. During a summer programme last month, as outdoor temperatures climbed into the upper 80s, Zedrik, a rising third grader, sat in the schoolyard beside a bush not tall enough to shade him entirely from the sun. Kenneth, a ninth grader, took refuge in the library. Nayla, an eighth grader, went to the director's office, where an air conditioner offered limited relief. The school has ceiling fans, but they don't operate at full strength. Other cooling equipment in the school doesn't work because it's been damaged by fluctuations in electrical voltage on an island dealing with an energy crisis. Students and teachers often suffer heat-related illnesses at schools in Puerto Rico, one of many places where extreme heat is disrupting children's education more frequently. Puerto Rico has developed guidelines for moving students to places with ventilation and air conditioning during extreme heat, but in practice, students often have limited options. The US territory in the Caribbean has made slow progress rebuilding school infrastructure damaged by Hurricane Maria in 2017 and earthquakes in 2020. Centro de Periodismo Investigativo in Puerto Rico is collaborating with The Associated Press, Honolulu Civil Beat, CalMatters, and Blue Ridge Public Radio to examine how school communities are recovering from natural disasters. Heat makes it harder for children to learn Exposure to extreme heat is linked to reduced cognitive function in childhood, particularly in socioeconomically disadvantaged communities. The smallest children are particularly vulnerable because they sweat less and have faster metabolisms, according to an analysis by the United Nations Children's Fund, UNICEF. Heat also acts as a psychological stressor, triggering anxiety and reducing memory capacity, said Nellie Zambrana, a school psychologist and professor at the University of Puerto Rico. 'In the afternoon, classes have to be much more strict than in the morning to keep students' attention. Otherwise the class just becomes, 'It's so hot, mister. It's so hot'," said Jose Quintana, a math teacher who suffered heat exhaustion himself at the school in Culebra, Escuela Ecologica, in 2023. The eastern educational region of Puerto Rico that includes Culebra reported 124 cases of students affected by extreme temperatures in 2024, according to data from the territory's education department. That's in line with a recent study that documented warming temperatures there and elsewhere around the island as a symptom of climate change. Across Puerto Rico, an island of 3.2 million people, there have been over 795 emergency room visits for illnesses related to heat exposure since 2023, and 20 per cent of them were by young people aged 18 or younger, according to the health department. The island government has acknowledged a need for more resilient schools to cope with heat waves, but many schools lack cross-ventilation and have cooling systems that are broken or insufficient. Students and teachers take a DIY approach to heat relief At Escuela Luis Munoz Marin in Yabucoa, in the island's southeast, the school community held raffles and collected a fee for dressing down on casual days to raise money to buy at least one fan for each classroom. Parents often send children to school with their own battery-powered fans to cope with the heat. Teachers have adapted by holding classes in the library, where there is air conditioning, said Josian Casanova, a history teacher at the high school. Last year, some students felt sick and had to leave because of the heat, he said. 'It's hard for teachers to focus when it's so hot," Casanova said. 'Imagine what it's like for students trying to concentrate." At the school in Culebra, the inconsistent power has also affected meal preparation. Changes in voltage have damaged equipment, including the ice machine and ceiling fans, said Maria Villanueva, who has worked at the school for five years. The three cafeteria staff members cook meals without a ventilation hood for the stove, and food spoils quickly because of heat and humidity in the storage room. The heat poses challenges for schools on the US mainland as well Over the last decade, demand for air conditioning at the start of the school year in the US has risen 34 per cent, according to an analysis from Climate Central, a science and communications nonprofit that researches climate change. In 2020, the US Government Accountability Office estimated that 41 per cent of school districts needed to upgrade or replace their heating, ventilation and air conditioning systems. Demand for electricity has risen just as the island has been dealing with an energy crisis. Hurricane Maria in 2017 destroyed the island's electrical grid. Since the launch of privatisation in 2021, electricity customers on average lose power four times a year for a total of about 13 hours. The island's government has invested more than USD 15 million since 2021 in air-conditioning equipment for 14 schools, but there isn't always enough power to run them, especially when demand spikes during afternoons in the summer. Escuela Luis Munoz Marin installed air conditioning units this year, but they don't have enough power to turn them all on, Casanova said. The school has been waiting two years for the government to upgrade the building's power substation. 'If the power goes, there are no other options," he said.

Is historically arid Beijing ready for a wetter future?
During last month's deadly floods in Beijing, rural hotel owner Cui Jian and his guests spent the night stranded on a rooftop in torrential rain before rescuers battled through metre-high mud and silt to get to them the next mountainous northern Huairou district and neighbouring Miyun district received a year's worth of rain in a single week, triggering flash floods that devastated entire villages and killed 44 people in the deadliest flood since authorities' most serious weather warning came too late for most villagers in Huairou, who were already asleep by the time it was issued. "In the past, they closed scenic areas and campsites, evacuated tourists and relocated villagers.
