The managment of silt washed down by the Himalyan rivers are key to mitigating flood risk in vulnerable regions across India
There are different methods to manage silt load. Soil conservation methods like crop rotation, use of organic matter, contour cultivation and restricted land use are some of the recommended methods of silt managment, especially in the catchment areas of rivers.
The coastal state of Maharashtra has three major rivers and several lakes, making it one of the few states in India having a vast water bank. However, most of its water bodies, including the Godavari, Krishna and Tapti rivers, are so polluted that they look like nullahs or drains. Heard about the Jayanthi and Gomati nullahs of Kolhapur? Well, according to water conservationist Rajendra Singh, they were once a water source but today we call them nullahs.
Froth belongs inside our washing machines. So, what is it doing there on the surface of our water bodies?
Water molecules prefer their own company, so they tend to stick together in drops. We call it surface tension. To make water wash better, we have to reduce its surface tension. The surfactants, that is, the surface active agents in detergents do the job.
The Han meets the Yamuna river and tells her how even she can flow and flourish in peace.
Han smiled and hugged Yamuna. For a moment, Yamuna forgot the toxic filled surrounding she lived in. Yamuna lowered her eyes and began opening up to Han. “Look where I live Han. I cannot breathe; move my arms or even my feet. Every day, the drains add more filth into the river and the people of the city for whom I travel from so far, do not even throw a glance at me. For them, I am a stinky black drain.”
A group of students raise awareness to preserve the beauty of wetlands
I have always enjoyed the trips and picnics our school takes us for. They are a good break from studies and a time to refresh our minds. This year, our school decided to take us to the Ropar wetlands in Punjab. But, we were not excited. We were hoping for a trip to Jaipur or some other historical place.
A few kids were tracking their paper boat in a river. Who was to say they would discover dirty truths.
During heavy rains, they overflow and flood courtyards. These become a breeding ground for mosquitoes. Open defecation near these drains causes the faecal matter to flow into households. The poorly designed toilet pits don't help either, he had explained. Pushpa was jolted when she heard the bell ringing and was swarmed into her class by the excited students.
It was the last day of the outdoor adventure camp. The campsite was right in the middle of lush green nature with the ethereal mountains by the side. It was a treasure trove of rare flora and fauna, a perfect storybook destination. Kind and friendly villagers lived in the nearby hamlet. It was these sights and sounds, the warmth of the people around, the fresh unpolluted air and the collective experience of everything around that made Praveen come here again and again. Praveen was the camp in-charge. Every year in the month of May, Praveen and his team organised nature-connect sessions for children.
They are known to have cradled civilisations, all over the world. They bathed, fed and helped carry humans. What are we talking about? Rivers, of course! With a twist to their modern profile, though, today they also serve as water suppliers for grand industries…
