Hydroponics may provide better agriculture solutions
Hydroponics offers opportunities to young farmers for startup business for the production of nutrient-rich spices, herbal and high value crops which has huge demand in the urban market. Posted on 26 Dec, 2019 07:45 PM

New Delhi, December 20 (India Science Wire): With rise in the population size the demand for food is also increasing and expected to increase up to 59 percent to 98 percent by 2050. Looking at this emerging demand hydroponics may be seen as a better technique of agriculture.

Aerosols increase drought severity over the Indian subcontinent
Study finds aerosols - suspended fine solid or liquid matter in the atmosphere - are adding to El Nino, which already deters the Indian monsoon. Posted on 10 Sep, 2019 12:24 PM

Pune, September 05 (India Science Wire): A team of atmospheric scientists from India, USA and Canada have found that aerosols in the atmosphere can increase the severity of droughts over the Indian subcontinent by as much as 17 per cent during El Nino years.

Experts say cold desert regions need special attention
Desertification at high altitudes increasing due to melting of glaciers, causing concern and a push to devise preventive adapation strategies. Posted on 06 Sep, 2019 10:38 AM

Greater Noida, September 5 (India Science Wire): Degradation of land, which leads to the process of desertification, is not limited to arid and semi-arid areas but is also visible in high altitude regions that get very little rainfall and are known as cold deserts.

Adequate water most important for plant diversity
Study shows how rainfall and temperature affect variety of plants in major bio-geographic zones of India Posted on 09 Jul, 2019 03:58 PM

New Delhi, July 9 (India Science Wire): India has a total geographical area of nearly 329 million hectares. The climate varies from the north to the south and east to west. However, in spite of this diversity, little is known about how climate affects the diversity of plants that grow in a particular area.

How can forecasting of extreme rainfall events be improved?
Greater precision in forecast of extreme events is critical. Posted on 05 Jul, 2019 12:00 AM

Mumbai, July 5 (India Science Wire): On July 2, the Maharashtra government decided to close private and public schools in Mumbai based on IMD’s rainfall forecast which predicted "intermittent rain in city and suburbs, with heavy to very heavy rainfall at a few places for the next 24 hours." The 24-hour period from 8:30 am of July 1 to July 2 saw a total of 375 mm of rain and it
