Plastic items from takeaway food and drink dominated the litter in the world’s oceans, according to a new study. The study, published in the journal Nature Sustainability was funded by the BBVA Foundation and the Spanish science ministry. The study shows that just 10 plastic products including plastic lids and fishing gear accounted for three-quarters of the litter. This is due to their widespread use and extremely slow rate of degradation. 

Global warming is causing hot places to become even hotter. Hence, animals in desert areas will feel more thirsty than ever before. Is the weather in your place warmer than it was last year? Think about it and colour the picture.

While there is no escape from washing hands regularly, we can definitely be more mindful of the way we use water and avoid its wastage.

According to the World Health Organization (WHO) guidelines on hygiene practices, the simple act of hand washing using a soap and water, is one of the most effective tools to protect us from getting infected by the coronavirus. Practices such as washing hands before and after eating or using the toilet, maintaining one-arm distance when around others and...

Salem is one of the largest cities in Tamil Nadu, India. More than 1 million people live here. Piyush Manush is the convener of the Salem Citizen's Forum (SCF). SCF is an informal group, involved in protecting Salem's environment. The lake was built by the British for irrigating nearby farmlands. The lake is spread across 58 acres and used to be a major water body of the city. But gradually it became a dumpsite for Salem's municipal solid waste. In 2010 SCF took over the work of cleaning the lake. But first, they had to get rid of the garbage and then desilt the waterbody.

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.

Carrying water by trains could be an emergency measure. Chennai has a strong tradition of water harvesting. But the problem is that most of these structures are either defunct or poorly maintained. Chennai which had 19 major lakes covering an area of 1130 hectares. But these waterbodies have been heavily encroached upon reducing their spread to just about 645 hectares. Its time that we understand the importance of water harvesting.

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?

Rivers are an essential part of our lives and the ecology. But we turn them into drains. Here is how we can help save our rivers.

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.”

When the rain gods do not send water for irrigation, farmers look downwards, at groundwater, for help. But, years of groundwater exploitation and lack of recharging, has led to a fall in the water tables. For instance, in north and central Gujarat, water tables have dropped to 20m per decade since 1974, as per a study by the Central Ground Water Board. If this continues, extracting groundwater will get more expensive because we have to dig deeper, or worse, groundwater will be only a myth for future generations.

Wetlands purify water through natural processes where aquatic plants act as bio-filters. Plants absorb phosphates and nitrates from the water and roots help to put back oxygen into the water.

Constructed wetlands are a cost-effective method of treating wastewater and polluted water bodies. These are low cost solutions and can be easily made or replicated.

Water is the essence of life, and we need to adopt practices to save and reuse it

How the life around the Yamuna River changed with time and people

Tributaries of the Yamuna flowed through the city and several rulers tapped the streams and fed the water through massive sluices into tanks, to provide water for their people. Today, these tributaries have dried up and become cemented tunnels underneath the city that carry sewage to the Yamuna.

Every monsoon the incidences of caving in increases. Nature or human activities–who is to blame?
