Definition: In this task, you are given a text of many news articles seperated by special token "|||||". Your task is to summarize them.
Input: Crops are wilting, schools have shut their bathrooms and government officials are bathing in lagoons because of a severe shortage of fresh water in a swath of the South Pacific. 
  
 The island groups of Tuvalu and Tokelau have declared emergencies, relying on bottled water and seeking more desalination machines. Parts of Samoa are starting to ration water. 
  
 Supplies are precariously low after a severe lack of rain in a region where underground reserves have been fouled by saltwater from rising seas that scientists have linked to climate change. 
  
 While nobody has gone thirsty yet, officials worry about the logistics of supplying everyone with enough water to survive and the potential health problems that might arise. And exactly how the islands will cope in the long term remains a question mark. 
  
 "We are praying that things will change," Samoan-based official Jovilisi Suveinakama said. 
  
 Six months of low rainfall have dried out the islands. Climate scientists say it's part of a cyclical Pacific weather pattern known as La Nina _ and they predict the coming months will bring no relief, with the pattern expected to continue. 
  
 Rising sea levels are exacerbating the problem, as salt water seeps into underground supplies of fresh water that are drawn to the surface through wells. 
  
 On the three main atolls that make up isolated Tokelau, the 1,400 residents ran out of fresh water altogether last week and are relying on a seven-day supply of bottled water that was sent Saturday from Samoa, Suveinakama said. 
  
 Suveinakama said that some schools no longer have drinking water available, and that the students often need to return home if they want to use a bathroom. 
  
 "In terms of domestic chores, like washing clothes, everything's been put on hold," he said. "We are cautious of the situation given the possible health issues." 
  
 Suveinakama said that Tokelau, a territory of New Zealand, has tapped emergency funds to buy desalination machines, which turn salt water into fresh water. He hopes those will be shipped to the islands soon. 
  
 In Tuvalu, a nation of low lying atolls that is home to less than 11,000 people, Red Cross team leader Dean Manderson described the situation as "quite dire." 
  
 He said that on the island of Nukulaelae, there were only 16 gallons of fresh water remaining Tuesday for the 350 residents and that the Red Cross was sending over two small desalination machines. 
  
 He said much of the well water on Tuvalu is unusable because it has become contaminated with salt water. 
  
 The New Zealand government this week flew a defense force C-130 plane to Tuvalu stocked with Red Cross supplies of bottled water and desalination machines. Officials including High Commissioner Gareth Smith also flew over to assess the situation. 
  
 Smith said the coconut trees on Tuvalu are looking sickly and that the edible breadfruit, which grow in trees, are much smaller than usual. He said other local fruits and vegetables, including a type of giant taro, are not growing well or are in short supply. 
  
 He said people in the capital of Funafuti are permitted a ration of two buckets of water per day and that government ministers have been bathing in the lagoon to preserve water. 
  
 Funafuti residents have been relying on a large desalination machine for much of their daily water supply, said Manderson. The Red Cross has been helping improve the function of that machine and has been fixing other such machines that have broken down, he added. 
  
 New Zealand climate scientist James Renwick said the rainfall problems can be traced back 12 months, when the region began experiencing one of the strongest La Nina systems on record. 
  
 La Nina is sparked when larger-than-normal differences in water temperature across the Pacific Ocean cause the east-blowing trade winds to increase in strength, Renwick said. That, in turn, pushes rainfall to the west, leaving places like Tuvalu and Tokelau dry. 
  
 Last year's La Nina system dwindled by June but has begun picking up again just ahead of the November rainy season, Renwick said, meaning that there is no relief in sight for island groups like Tuvalu, Tokelau and Samoa. 
  
 "Low rainfall continues to be on the cards, at least through the end of the year," Renwick said. 
  
 Officials say they are concentrating on the short-term supply problems and have not yet had time to think about longer term solutions for the islands. But they say that the combination of rising water levels and low rainfall mean makes life on the islands look increasingly precarious. ||||| Image caption Water supplies will have to be brought to Tokelau by barge from ships anchored offshore 
  
 A second South Pacific community is suffering a severe water shortage due to an ongoing drought crisis. 
  
 Tokelau declared a state of emergency late on Monday, following a similar move in neighbouring Tuvalu, where water is already being rationed. 
  
 A New Zealand-administered territory of three islands, Tokelau's 1,400 people have less than a week's drinking water left. 
  
 The lack of rainfall is blamed on the La Nina weather pattern. 
  
 Officials said Tokelau had run out of natural fresh water and was relying solely on bottled water. 
  
 New Zealand Foreign Minister Murray McCully said other islands in the South Pacific were also reporting water shortages. 
  
 Parts of Samoa have begun rationing water. 
  
 He said New Zealand was rushing to assess the situation throughout the region, amid fears the crisis could escalate. 
  
 This is having a severe impact on crops, so there's likely to be a food shortage as well Murray McCully, NZ Foreign Minister 
  
 New Zealand was "making sure we deal with the drinking water issue most urgently", he said. 
  
 A New Zealand Air Force plane landed in Tuvalu on Monday carrying containers of water and desalination units. 
  
 Tuvalu, one of the world's smallest independent nations, with a population of about 11,000, lies about halfway between Australia and Hawaii. Tokelau is about 500km (310 miles) to the east. 
  
 Impact on crops 
  
 Mr McCully said the situation was urgent in parts of Tuvalu. 
  
 He said there was less than a week's supply of drinking water on Funafuti, the main island of Tuvalu. 
  
 "I understand one of the other outlying islands, Nukulaelae, has a more urgent shortage and there is a desalination plant on the way there," Mr McCully said. 
  
 "There are going to be some flow-on effects here, clearly this is having a severe impact on crops, so there's likely to be a food shortage as well." 
  
 La Nina causes extreme weather, including both drought and floods, and was blamed for floods in Australia, South East Asia and South America in late 2010 and early 2011. 
  
 David Hebblethwaite, a water conservation expert with the Secretariat of the Pacific Community, said Tuvalu had experienced low rainfall for the past three years and there had been no precipitation at all for seven months. 
  
 He said Funafuti and Nukulaelae both lacked groundwater supplies, making them dependent on rainfall collected from the roofs of homes and government buildings. 
  
 Mr Hebblethwaite said the islands may also need extra medical supplies if water shortages lead to sanitation issues and consequent health problems. |||||
Output:
Some island groups in the South Pacific, already in danger of being swamped by rising seas, have run out of fresh water. Tuvalu and Tokelau have declared states of emergency because of the water crisis, caused by six months of low or no rainfall and by groundwater becoming contaminated with seawater, the BBC reports. New Zealand's air force has rushed bottled water and desalination machines to the areas most in need. In Tuvalu, a nation of atolls that is home to around 11,000 people, the situation is "quite dire," a Red Cross team leader says. The crisis is spreading, with Samoa now rationing water, and experts believe that because of La Niña, the region won't see any rainfall until at least until the end of the year. The water crisis is expected to trickle down into food shortages, and sanitation and public health problems, the AP reports, and officials say the future of the island nations is looking increasingly uncertain.
