Rio de Janeiro Governor Luiz Fernando Pezao on Monday signed a deal with several Brazilian universities and research institutes to develop a plan to clean up the polluted waters of the city’s sewage-strewn Guanabara Bay, where Olympic sailing events are to be held.
Pezao hailed the deal as a “very important step” toward the long-promised cleanup, which has dragged on for more than 20 years with little progress.
As part of Brazil’s Olympic project, authorities pledged more than six years ago to drastically cut the amount of raw human sewage in the bay before next year’s Games. However, only one of the eight promised treatment plants aimed at filtering much of the waste out of the rivers that have become open-air sewage ditches has been built, and the bay’s once-crystalline waters remain fetid.

An Associated Press investigation published last week revealed high counts of disease-causing viruses directly linked to human sewage in waters to be used for Olympic events.
In a statement from his office, Pezao was quoted as saying that since Rio won its Olympic bid in 2009, the city has boosted the treatment of sewage that once flowed into the bay from 17 percent to 49 percent. The original promise was to treat 80 percent of sewage that ends up in the bay by next year’s Games, but state and municipal officials have repeatedly acknowledged there is no way that pledge will be met.
Internet portal UOL quoted Pezao as saying: “We made a mistake. We can’t continue to make more mistakes.”
He added that the government would not commit to any further cleanup targets before the necessary studies have been completed, the UOL report said.
It also quoted Rogerio Vale, who was representing Rio’s federal university at Monday’s signing event, as saying: “We’re working toward a gradual plan and a long-term recuperation of the bay. We’re talking about 20 years. The bay can be in good shape in 2025, 2030 or even 2035.”
Seven universities — six of them public institutions — as well as several research institutes are to develop the new cleanup plan.
Four-time NBA all-star DeMarcus Cousins arrived in Taiwan with his family early yesterday to finish his renewed contract with the Taiwan Beer Leopards in the T1 League. Cousins initially played a four-game contract with the Leopards in January. On March 18, the Taoyuan-based team announced that Cousins had renewed his contract. “Hi what’s up Leopard fans, I’m back. I’m excited to be back and can’t wait to join the team,” Cousins said in a video posted on the Leopard’s Facebook page. “Most of all, can’t wait to see you guys, the fans, next weekend.

Revelations of positive doping tests for nearly two dozen Chinese swimmers that went unpunished sparked an intense flurry of accusations and legal threats between the World Anti-Doping Agency (WADA) and the head of the US drug-fighting organization, who has long been one of WADA’s fiercest critics. WADA on Saturday said it was turning to legal counsel to address a statement released by US Anti-Doping Agency (USADA) CEO Travis Tygart, who said WADA and anti-doping authorities in China swept positive tests “under the carpet by failing to fairly and evenly follow the global rules that apply to everyone else in the world.” The
Taiwanese judoka Yang Yung-wei on Saturday won silver in the men’s under-60kg category at the Asian Judo Championships in Hong Kong. Nicknamed the “judo heartthrob” in Taiwan, the Olympic silver-medalist missed out on his first Asian Championships gold when he lost to Japanese judoka Taiki Nakamura in the finals. Yang defeated three opponents on Saturday to reach the final after receiving a bye through the round of 32. He first topped Laotian Soukphaxay Sithisane in the round of 16 with two seoi nage (over-the-shoulder throws), then ousted Indian Vijay Kumar Yadav in the quarter-finals with his signature ude hishigi sankaku gatame (triangular armlock). He
Rafael Nadal on Wednesday said the upcoming French Open would be the moment to “give everything and die” on the court after his comeback from injury in Barcelona was curtailed by Alex de Minaur. The 22-time Grand Slam title winner, back playing this week after three months on the sidelines, battled well, but eventually crumbled 7-5, 6-1 against the world No. 11 from Australia in the second round. Nadal, 37, who missed virtually all of last season, is hoping to compete at the French Open next month where he is the record 14-time champion. The Spaniard said the clash with De Minaur was
