Water Spouts will speak volubly and endlessly about all the issues concerning water. The ongoing degradation, and growing scarcity, of the water supply here in the US, and the rest of the world. The continued absence of potable water in so many parts of the world. The work being done by NGOs, and charities, in the third world, to help alleviate the situation. The emphasis on WASH ( Water, Sanitation, and Hygiene ) so health and healthy water are maintained. "Water Spouts" will spout it all out.
Research Reveals Carbon Footprint Caused by China's Irrigation System

China’s groundwater irrigation system is responsible for polluting the atmosphere with more than 30 million tonnes of CO2 per year – according to research from the University of East Anglia.
Groundwater used for crop irrigation in China has grown from 10 billion cubic metres in 1950 to more than 100 billion today.
A research paper, published today in Environmental Research Letters,
estimates that the pumping systems which support this immense irrigation
network annually produce 33.1 MtCO2e (33.1 mega tonnes of carbon dioxide equivalent).
China is the largest greenhouse gas emitter in the world, with around
17 per cent of emissions coming from agriculture. Irrigated agriculture
in China produces 70 per cent of the country’s grain. But it takes some
500 litres of water to grow the wheat for one small loaf of bread.
Pollution is caused by the huge amount of energy needed to pump water
from underground – in some areas from an average depth of 70 meters.
This research is the first to calculate how much pollution is being
It is the result of a collaboration between the university’s School
of International Development, the UEA Water Security Research Centre and
the UEA-based Tyndall Centre for Climate Change Research, with the
Centre for Chinese Agricultural Policy, the Chinese Academy of
Agricultural Sciences and Cranfield University.
The research team used extensive survey data collected from 366
villages in 11 provinces. They up-scaled these results to calculate the
emissions created by groundwater pumping across China’s remaining 20
The results account for more than 0.5 per cent of China’s total CO2 emissions. For comparison, this is similar to the total amount of CO2 that the whole of New Zealand emits in one year. Read email@example.com
