In 1986, the Government of India, under then Prime Minister Rajiv Gandhi, designated February 28 as National Science Day to commemorate the announcement of the discovery of the “Raman Effect”. This year’s edition is being celebrated under the theme of “Global Science for Global Wellbeing”, in light of India’s G20 presidency.

The Raman Effect was the discovery which won physicist Sir CV Raman his Nobel Prize in 1930. Conducting a deceptively simple experiment, Raman discovered that when a stream of light passes through a liquid, a fraction of the light scattered by the liquid is of a different colour. This discovery was immediately recognized as groundbreaking in the scientific community, being the subject of over 700 papers in the first seven years after its announcement

Across the globe, societies vary widely in the natural resources they use and how they govern these resources. This diversity has enabled humans to successfully live in a wide variety of landscapes, but surprisingly little is known about why these practices vary so widely and how they change over time. Researchers at Colorado State University’s Warner College of Natural Resources and partners are setting out to identify the drivers of change in natural resource management strategie

Various academic fields point to different factors as possible influences on natural resource management systems, including environmental conditions, social structures, history and the use of information passed on from ancestors and neighboring groups. But the limitations of previous research methods have meant that evidence to support these hypotheses is mixed at best.
