Unplanned Industrialisation: Curse on the Sutang

Unplanned Industrialisation: Curse on the Sutang International Day of Action for Rivers: The Shoiljura, a canal of what looks like a stream of slurry, was re-excavated by the authorities to irrigate surrounding farms with water from the Sutang river in Habiganj. Thanks to industrial waste, it is now a hazard for the villagers nearby and the river.

Seven years later, the canal has become a means of hazard for nearby villagers and the river itself.

Water is everywhere: oxygen signals in tree rings shows climate changes and the water cycle

δ 18O or written as ‘delta-O-18’. Delta-O-18 is a measure of the ratio of the stable isotopes oxygen-18 ( 18O) and oxygen-16. It is commonly used as a measure of the temperature of precipitation, as a measure of groundwater and mineral interactions, and as an indicator of processes that show isotopic fractionation. The latter is an important tool to understand geochemical and biological systems. For example, biochemical processes cause changes in ratios of stable carbon isotopes in biomass. This is what scientists from the Institute of Geography at Friedrich-Alexander University Erlangen in Germany, World Agroforestry (ICRAF), and the Department of Forestry and Environmental Science at Shahjalal University of Science and Technology in Bangladesh used in an experiment with three South Asian tree species. Their findings were published in the journal,
