History Doesn’t Repeat Itself—Not Here, Anyway (USA). After discussions and deliberation between cities, states, and the federal government, many of these flood-damaged and flood-prone lands were converted into open space through government acquisitions, or “buyouts.” After 1993, parks and fields were created where homes had once stood. These areas were now easier to maintain and protect. Children could play football or soccer. Families could picnic in the summertime and build snowmen in the winter.

Record Missouri flooding was manmade calamity, scientist says Most news reports blamed it on the heavy rain, but a professor of earth and planetary sciences says analysis of the flood data shows much of the damage was due to recent modifications to the river. The flood on the middle Mississippi River, in turn, was remarkable for its short duration and the time of year. "It was essentially a winter flash flood on a continental-scale river," Criss said. "The Mississippi has been so channelized and leveed close to St. Louis that it now responds like a much smaller river." "In the meantime," he said, "inaccurate Federal Emergency Management Agency flood frequencies based on the assumption that today's river will behave as it has in the past greatly underestimate our real flood risk and lead to inappropriate development in floodways and floodplains." "The heavy rainfall was probably related to El Niño, and possibly intensified by global warming. But new records were set only in areas that have undergone intense development, which is known to magnify floods and shorten their timescales. "People want to blame the rain, but this is mostly us," Criss said. "It's a manmade disaster." During the New Year's flood, roughly 7,000 buildings near St. Louis were damaged, two interstate highways were closed for several days, the community of Valley Park was evacuated, and two Metropolitan Sewer District plants were swamped so that sewage was dumped directly into the water. The flood killed more than 20 people in Missouri and Illinois, caused several hundred million dollars of damage, and left millions of tons of debris in its wake.

The best way to protect us from climate change? Save our ecosystems There is now clear evidence that intact forests have a positive influence on both planetary climate and local weather regimes. Forests also provide shelter from extreme weather events, and are home to a host of other valuable ecosystems that are important to human populations as sources of food, medicine and timber. In Vietnam, 12,000 hectares of mangroves have been planted at a cost of US$1.1 million, but saving the US$7.3 million per year that would have been spent on maintaining dykes. In Louisiana, the destruction of Hurricane Katrina in 2005 led to an examination of how coastal salt marshes might have reduced some of the wave energy in the hurricane-associated storm surges. Data have now confirmed that salt marshes would have significantly reduced the impact of those surges, and stabilised the shoreline against further insult, at far less cost than engineered coastal defences. With this data in hand, discussions are now beginning around how to restore the Louisiana salt marshes to insulate against future extreme weather events.

Flavour of Dutch dialogues gets into 1 billion dollar US disaster resilience plans Morris has been closely involved in the competition and emphasises the tremendous Dutch influence in these projects. In particular, he mentions the climate adaptive approach that focusses on disaster prevention, and on the involvement of many stakeholders right from the start. "This is a distinct Dutch approach to urban planning", says Morris. "Also the involvement of landscape architecture shows the Dutch influence in these projects". "With the two competitions the housing department provokes the states and the local communities to think about their future and the social-economic development. The US is well organized on reactive disaster response. The competitions made them think of the future and long term planning for smart investments."

UN agricultural agency helps Pakistan cope with natural disasters such as floods, quakes, droughts

With a 21 percent share of the national gross domestic product (GDP) and a 45 percent share of Pakistan's total workforce, it is crucial that agriculture be able to prevent and mitigate the impact of disasters.

Human-made climate change helped cause south of England floods, say scientists anthropogenic greenhouse gas emissions increased the risk of the once-a-century wet January in 2014 by 43% (uncertainty range: 0-160%). The heightened risk of rainfall found in the meteorological modelling led to an increase in the peak 30-day river flow of 21% (uncertainty range: -17-133%) and about 1,000 more properties at risk of flooding (uncertainty range: -4,000-8,000).

Borrowed Time on Disappearing Land (Bangladesh) “These migrants should have the right to move to the countries from which all these greenhouse gases are coming. Millions should be able to go to the United States.” Making matters worse, much of what the Bangladeshi government is doing to stave off the coming deluge — raising levees, dredging canals, pumping water — deepens the threat of inundation in the long term. In an analysis of decades of tidal records published in October, Dr. Pethick found that high tides in Bangladesh were rising 10 times faster than the global average. He predicted that seas in Bangladesh could rise as much as 13 feet by 2100, four times the global average. “The reaction among Bangladeshi government officials has been to tell me that I must be wrong,” he said. “That’s completely understandable, but it also means they have no hope of preparing themselves.” “There is no doubt that preparations within Bangladesh have been utterly inadequate, but any such preparations are bound to fail because the problem is far too big for any single government,” said Tariq A. Karim, Bangladesh’s ambassador to India. “We need a regional and, better yet, a global solution. The family reunited on the road the next day after the children spent a harrowing night avoiding snakes that had sought higher ground, too. They drank rainwater until rescuers arrived a day or two later with bottled water, food and other supplies. In the weeks after the storm, the women of Dakope found firewood by wading into the raging river and pushing their toes into the muddy bottom. They walked hours to buy drinking water. “I don’t want to stay here (slums) for too long,” Mr. Gazi said. “If we can save some money, then we’ll go back. I’ll work on a piece of land and try to make it fertile again.” But the chances of finding fertile land in his home village, where the salty rivers have eaten away acre upon acre, are almost zero.
