Sustainability and Water August 12, Water tables all over the world are falling, as "world water demand has tripled over the last" 50 years. When these aquifers are depleted, food production worldwide will fall.
Why is Pakistan running dry?
Pakistan could "run dry" by as its water shortage is reaching an alarming level. The authorities remain negligent about the crisis that's posing a serious threat to the country's stability, reports Shah Meer Baloch.
According to a recent report by the International Monetary Fund IMFPakistan ranks third in the world among countries facing acute water shortage. It is not the first time that development and research organizations have alerted Pakistani authorities about an impending crisis, which some analysts say poses a bigger threat to the country than terrorism.
InPCRWR reported that Pakistan touched the "water stress line" in and crossed the "water scarcity line" in Devastating effects of climate change Sweltering heat Unprecedented heat waves swept across the globe inleading to droughts, wildfires and even deaths.
Australia started the year with temperatures near 50 degrees Celsius Fahrenheitthe "Lucifer" heat wave brought the mercury above 40 degrees Celsius throughout Southern Europe in July and August and scorching heat hit India's most vulnerable people.
Get ready for next summer Devastating effects of climate change Disappearing wonder Earlier this year, scientists realized that coral bleaching in Australia's Great Barrier Reef was worse than first thought.
Byscientists have warned 90 percent of the reef could disappear. Rising sea temperatures and ocean acidification are the main culprits. Devastating effects of climate change Deadly combination Armed conflicts are pushing millions of people to leave their homes or live in terribly precarious situations — and climate change is making it worse.
A lack of natural resources increases the risk of conflict and makes life even harder for refugees. South Sudanese families, for instance, are escaping to neighboring countries like Uganda and Kenya — countries already suffering from drought. Global warming has been blamed for the increased fire risk, and in some countries that risk has turned into reality.
Wildfires engulfed large areas of Europe's Iberian Peninsula, causing death and destruction, while firefighters in California have had no rest for more than six months.
Devastating effects of climate change Record-shattering storms Hurricanes Maria and Irma, which hit the Caribbean region in August and September, were two of the year's most damaging weather events. Warming of the ocean surface has led to more evaporation, and that water may help fuel thunderstorms and hurricanes.
Devastating effects of climate change Melting Antarctica In July, one of the largest icebergs ever recorded separated from the Larsen C ice shelf — one of Antarctica's biggest — reducing its area by more than 12 percent.
While calving icebergs in the Antarctic are part of a natural cycle, scientists have linked the retreat of several Antarctic ice shelves to global warming and are closely monitoring potential long-term effects. Devastating effects of climate change Struggle to breathe Deteriorating air quality causes thousands of deaths around the world every year.
India's capital, New Delhi, is one of the world's most polluted cities."Heat waves and droughts in Pakistan are a result of climate change," Mian Ahmed Naeem Salik, an environmental expert and research fellow at the Institute of Strategic Studies in Islamabad, told DW. The scarcity of food is caused by economic, environmental and social factors such as crop failure, overpopulation and poor government policies are the main cause of food scarcity in most countries.
Environmental factors determine the kind of crops to be produced in a given place, economic factors determine the buying and production capacity and socio-political factors determine distribution of food .
Physical water scarcity prevails in those regions where surface and groundwater resources are inadequate to supply the region’s water demands. In economic water scarcity regions, water resources are abundant but scarcity is observed due to mismanagement of optimally available supplies.
"The overriding challenge for our generation is to build a new economy–one that is powered largely by renewable sources of energy, that has a much more diversified transport system, and that reuses and recycles everything." –Lester R. Brown, Plan B Mobilizing to Save Civilization.
While discussing the UNDP report "Development Advocate Pakistan," Shamsul Mulk, former chairman of the Water and Power Development Authority, said that water policy is simply non-existent in Pakistan. significance and a high priority is placed on water resources management.
Some water shortages can be the result of overappropriation of supply so that “drought” occurs even in years of “normal” precipitation.
