A report issued on the eve of the first major UN conference on water in more than 45 years says 26 percent of the world’s population does not have access to safe drinking water and 46 percent lacks access to basic sanitation.
The UN World Water Development Report 2023, released on Tuesday, painted a stark picture of the huge gap that needs to be filled to meet UN goals to ensure all people have access to clean water and sanitation by 2030.
Richard Connor, editor-in-chief of the report, told a news conference that the estimated cost of meeting the goals is between US$600 billion and US$1 trillion a year.

However, equally important is forging partnerships with investors, financiers, governments and climate change communities to ensure that money is invested in ways to sustain the environment and provide potable water to the 2 billion people who do not have it and sanitation to the 3.6 million in need, he said.
Water use has been increasing globally by about 1 percent per year over the past 40 years “and is expected to grow at a similar rate through 2050, driven by a combination of population growth, socioeconomic development and changing consumption patterns,” the report says.
Connor said that actual increase in demand is happening in developing countries and emerging economies where it is driven by industrial growth, especially by the rapid increase in the population of cities.
With agriculture using 70 percent of all water globally, irrigation for crops has to be more efficient — as it is in some countries that now use drip irrigation, which saves water, he said.
“That allows water to be available to cities,” he said.
As a result of climate change, “seasonal water scarcity will increase in regions where it is currently abundant — such as Central Africa, East Asia and parts of South America — and worsen in regions where water is already in short supply, such as the Middle East and the Sahara in Africa,” the report says.
On average, “10 percent of the global population lives in countries with high or critical water stress,” and up to 3.5 billion people live under conditions of water stress at least one month a year, the report says.
RETHINK? The defense ministry and Navy Command Headquarters could take over the indigenous submarine project and change its production timeline, a source said Admiral Huang Shu-kuang’s (黃曙光) resignation as head of the Indigenous Submarine Program and as a member of the National Security Council could affect the production of submarines, a source said yesterday. Huang in a statement last night said he had decided to resign due to national security concerns while expressing the hope that it would put a stop to political wrangling that only undermines the advancement of the nation’s defense capabilities. Taiwan People’s Party Legislator Vivian Huang (黃珊珊) yesterday said that the admiral, her older brother, felt it was time for him to step down and that he had completed what he
Taiwan has experienced its most significant improvement in the QS World University Rankings by Subject, data provided on Sunday by international higher education analyst Quacquarelli Symonds (QS) showed. Compared with last year’s edition of the rankings, which measure academic excellence and influence, Taiwanese universities made great improvements in the H Index metric, which evaluates research productivity and its impact, with a notable 30 percent increase overall, QS said. Taiwanese universities also made notable progress in the Citations per Paper metric, which measures the impact of research, achieving a 13 percent increase. Taiwanese universities gained 10 percent in Academic Reputation, but declined 18 percent
UNDER DISCUSSION: The combatant command would integrate fast attack boat and anti-ship missile groups to defend waters closest to the coastline, a source said The military could establish a new combatant command as early as 2026, which would be tasked with defending Taiwan’s territorial waters 24 nautical miles (44.4km) from the nation’s coastline, a source familiar with the matter said yesterday. The new command, which would fall under the Naval Command Headquarters, would be led by a vice admiral and integrate existing fast attack boat and anti-ship missile groups, along with the Naval Maritime Surveillance and Reconnaissance Command, said the source, who asked to remain anonymous. It could be launched by 2026, but details are being discussed and no final timetable has been announced, the source
CHINA REACTS: The patrol and reconnaissance plane ‘transited the Taiwan Strait in international airspace,’ the 7th Fleet said, while Taipei said it saw nothing unusual The US 7th Fleet yesterday said that a US Navy P-8A Poseidon flew through the Taiwan Strait, a day after US and Chinese defense heads held their first talks since November 2022 in an effort to reduce regional tensions. The patrol and reconnaissance plane “transited the Taiwan Strait in international airspace,” the 7th Fleet said in a news release. “By operating within the Taiwan Strait in accordance with international law, the United States upholds the navigational rights and freedoms of all nations.” In a separate statement, the Ministry of National Defense said that it monitored nearby waters and airspace as the aircraft
