A worldwide review of global rainfall data led by the University of Adelaide has found that the intensity of the most extreme rainfall events is increasing across the globe as temperatures rise.
In the most comprehensive review of changes to extreme rainfall ever undertaken, researchers evaluated the association between extreme rainfall and atmospheric temperatures at more than 8000 weather gauging stations around the world.
Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) - host of one of UN-SPIDER's Regional Support Offices - conducted a five-day training/workshop on “Flood Risk Mapping Using Spatial Technologies” from 5 to 10 December, 2012.
Heavy rain swept across the UK over the weekend of 22 and 23 December. This resulted in flooding across the country, particularly affecting south-west England and Wales. The activation of the International Charter "Space and Major Disasters" was requested on 21 December 2012 with the Environment Agency (of England and Wales) being the project manager.
The International Charter "Space and Major Disasters" was activated on 27 November 2012 by the Environment Agency of England and Wales, after widespread floods had hit a number of regions. Among the affected areas are: Somerset levels, Oxford, Tewkesbury, Darlington to York, Nene Washlands, and Nottingham. Approximately 1,800 properties have flooded since last Wednesday, while flood defences have protected more than 54,000 homes. Over 106,000 properties have been sent a flood warning.
Nigeria continues to be heavily affected by floods. The country’s National Emergency Management Agency reported that floods had killed 431 people and displaced 1.3 million more. Floods had also wiped out 152,575 hectares (377,020 acres) of farmland, and Nigerians could expect rapidly rising food prices as a result.
The UN-SPIDER Regional Support Office in Ukraine (Space Research Institute NASU-NSAU) supported the relief efforts following the September floods in Cameroon by providing flood maps. In September 2012, the northern part of Cameroon was hit by severe floods. Subsequently, the International Charter “Space and Major Disasters” was activated to acquire satellite images over affected regions.
On 18 September 2012, the International Charter: Space and Major Disasters was activated for floods in Pakistan. Torrential rain, which began on 5 September, had caused flash floods in Pakistan leaving an estimated one million people homeless.
The International Charter Space and Major Disasters was activated for floods on Thursday 6 September 2012 in the region of Maga, Mayo-Danay, Cameroon. The Charter was activated by the United States Geological Survey (USGS) on behalf of Civil Protection Directorate, Cameroon.
