what are the major differences between the two methodologies green and brown
Archaeoastronomy When debates polarise between techniques, the methods are often referred to by a colour code, based on the colours of the bindings of the two volumes from the first Oxford Conference, where the approaches were first distinguished.[53] Green (Old World) archaeoastronomers rely heavily on statistics and are sometimes accused of missing the cultural context of what is a social practice. Brown (New World) archaeoastronomers in contrast have abundant ethnographic and historical evidence and have been described as 'cavalier' on matters of measurement and statistical analysis.[54] Finding a way to integrate various approaches has been a subject of much discussion since the early 1990s.[55][56]
Green Revolution in India The Green Revolution in India was a period when agriculture in India increased due to improved method & technology. The Green Revolution allowed developing countries, like India, to overcome poor agricultural productivity. It started in India in the early 1960s and led to an increase in food grain production, especially in Punjab, Haryana and Uttar Pradesh during the early phase. The main development was higher-yielding varieties of wheat, which were developed by many scientists, including Indian geneticist M. S. Swaminathan, American agronomist Dr. Norman Borlaug, and others. The Indian Council of Agricultural Research also claims credit for Udit Singhal[1] for developing rust resistant strains of wheat.[2]
