Indian Ocean Warming leads to change in the Rainfall Pattern and Groundwater Storage in India

Kolkata, Jan 10, 2017:  The changing rainfall pattern, which is linked to the warming of the Indian Ocean, is the key factor driving changes in groundwater storage in India. This is reported by a new study led by the Indian Institute of Technology (IIT) in Gandhinagar.

Published in the journal Nature Geoscience in January, the study shows that changing monsoon patterns “which are tied to higher temperatures in the Indian Ocean” are an “even greater driver of change” in groundwater storage than the pumping of groundwater for agriculture.

“Groundwater plays a vital role in food and water security in India. Sustainable use of groundwater resources for irrigation is the key for future food grain production,” said study leader Vimal Mishra, of IIT Gandhinagar. “And with a fast-growing population, managing groundwater sustainability is becoming even more important.

The linkage between monsoon rainfall and groundwater can suggest ways to enhance groundwater recharge in India and especially in the regions where rainfall has been declining, such as the Indo-Gangetic Plain,” he added. Groundwater withdrawals in the country have increased over ten-fold since the 1950s, from 10-20 cubic kms per year in 1950 to 240-260 cubic kms per year in 2009. And satellite measurements have shown major decline in groundwater storage in some parts of the country, particularly in northern India, the study notes.

“This study adds another dimension to the existing water management framework. We need to consider not just the withdrawals, but also the deposits in the system,” said Yoshihide Wada, co-author and the deputy director of the Water programme at the International Institute for Applied Systems Analysis in Austria.

By looking at water levels in wells around the country, the researchers could track groundwater replenishment following the monsoon. In addition, the researchers found that the monsoon precipitation is correlated with Indian Ocean temperature, a finding which could potentially help to improve precipitation forecasts and aid in water resource planning.

“Weather is uncertain by nature, and the impacts of climate change are extremely difficult to predict at a regional level. But our research suggests that we must focus more attention on this side of the equation if we want to sustain manage water resources for the future”, Wada added. (IANS)

EU Countries Consume Earth’s Resources Faster than they can be Renewed: Report

Some 100 Greenpeace activists and students from several European countries marched through Sibiu carrying a huge banner saying "Broken Climate Broken Future"

The European Union’s 28 countries consume the Earth’s resources faster than they can be renewed and none of them has sustainable consumption policies, a report released Thursday said, as EU leaders met to discuss priorities for the next five years.

“All EU countries are living beyond the means of our planet. The EU and its citizens are currently using twice more than the EU ecosystems can renew,” the report by the World Wide Fund (WWF) and Global Footprint Network said. It was issued as leaders met in the Romanian city of Sibiu to set the course for the bloc after Britain’s planned departure from the EU.

Climate change key priority

French President Emmanuel Macron said before the summit that climate change was among his key priorities and it was included in the bloc’s 10 “commitments” for the future until 2024, agreed by all the 27 leaders meeting in Sibiu.

But the bloc is divided on how to achieve any ambitious climate goals and it remains far from clear how the Sibiu declaration would be implemented. Some 100 Greenpeace activists and students from several European countries marched through Sibiu carrying a huge banner saying “Broken Climate Broken Future.”

“We cannot talk about a prosperous future without a healthy climate,” Greenpeace climate activist Alin Tanase told Reuters. Views on concrete action to be taken to combat climate change differ between EU countries, influenced greatly by their dominant industries, such as carmakers in Germany or the coal industry in Poland.

Tusk sensitive to climate change

The chairman of the summit, President of the European Council Donald Tusk, said there was no future for politicians who were not sensitive to climate change and environment protection issues.

“The young generation is much more united on this than the member states. The truth is that nothing has changed when it comes to this divide and different opinions about this. What is new is this very fresh and energetic pressure,” he told a news conference after the summit.

Climate protection and sustainable development is also an important topic in the election campaign for the May 23-26 European Parliament elections, which will influence the leadership of European institutions and their programs.

The European Commission has been pushing for the EU to become climate neutral by 2050 through reducing carbon emissions that will otherwise boost the Earth’s average temperatures with devastating consequences.

“The EU uses up almost 20 percent of the Earth’s bio-capacity although it comprises only 7 percent of the world population,” the WWF report said. “In other words, 2.8 planets would be needed if everyone consumed at the rate of the average EU resident,” it said.

Luxembourg smallest but fastest

It said the EU’s smallest and richest country, Luxembourg, was also the one which used up renewable resources the fastest last year. Just 46 days into the year, it had consumed its full share of the Earth’s resources, it said.

The EU’s poorest nation, Romania, took the longest to arrive at that point, on July 12th. But that was still earlier than the world’s average of Aug. 1, called Earth overshoot day. (VOA)
