Snow is not unusual in Afghanistan; in fact, a deep snow
pack is necessary if the country is to have water during the dry summer
months. But January 2006 hit the Central Asian country harder than normal.
Heavy snow and extreme cold destroyed or damaged at least 86 homes and
killed 17 people, with twice as many more injured, reported the
International Federation of Red Cross and Red Crescent Societies.
Much of the damage occurred after a blizzard hit the northernmost
provinces particularly hard on January 31. On February 3, the Moderate
Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this clear view
of Afghanistan covered in snow. In addition to covering the rugged
mountains that run down the spine of the country, the snow stretches across
the populated northern plains where the damage was reported.
Despite the problems the January 2006 storms caused, Afghanistan needs
its winter snow. Like the U.S. West, water during the summer comes from the
melting snow pack in the mountains. Without the snow, farmers would have no
way to irrigate summer crops. The snow is such an essential ingredient to
the success of crops in Afghanistan that the Famine Early Warning Network
(FEWS NET) monitors snow cover to help gauge how much food aid might be
needed after the next growing season and harvest.
MODIS images such as this
one help analysts at FEWS NET determine the extent of snow cover in
Afghanistan. Knowing how much snow is in the mountains can reveal how much
water will be available for crops during the next summer. If insufficient
snow falls during the winter, FEWS NET can issue a warning to aid agencies
and the government to alert them to the potential crop failure and a
possible future need for food aid. The advance warning gives agencies and
the government time to gather the resources they need to prevent a crisis. To

Afghanistan on the Earth Observatory.
