Sharing water, reaping benefits
This study finds that smallholder farmers who undertake group micro irrigation through pooling of land and water resources greatly benefit through increase in productivity and profit margins. Posted on 14 Apr, 2018 05:06 PM

Agriculture is of central importance to India’s economy with more than half of the workforce in the country depending on it for their livelihoods. However, it is increasingly being threatened due to climate-change-induced changing rainfall patterns and water scarcity having a negative impact on production.

Nanomaterial from seaweed can clean toxic water
A team of scientists have synthesised graphene-iron sulfide nanocomposite from abundantly found seaweed Ulva fasciata through direct pyrolysis technique. Posted on 08 Apr, 2018 09:02 PM

Treatment of wastewater containing industrial dyes and toxic heavy metals is a major environmental problem as available treatment techniques are not very efficient and environment-friendly. Now a team of Indian scientists has developed a nanomaterial drawn from seaweed for effective treatment of toxic wastewater without using any chemicals.

Anthropogenic warming and climate change
A study shows extreme rainfall events in India are linked to man-made emissions. Posted on 28 Mar, 2018 11:23 AM

Here is more evidence why we need to worry about climate change. A new study says extreme rainfall events are on the rise in India and attributes the trend to man-made emissions, what scientists call anthropogenic warming. Not just this, the trend is likely to become more prominent by mid-century, particularly in southern and central India.

Man-made emissions is one of the reasons for extreme rainfall events in India. (Photo: IWP Flickr photos; photo for representation only)
