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 refers to a period of time when agriculture in India changed to an industrial system due to the adoption of modern methods and technology such as high yielding variety (HYV) seeds, tractors, irrigation facilities, pesticides, fertilizers etc. This was part of the larger Green revolution started by Norman Borlaug, which leveraged agricultural research and technology to increase agricultural productivity in the developing world. Within India, this started 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,[2] and rust resistant strains of wheat.[3]
