Evergreen Revolution was a term coined by M.S. Swaminathan to indicate the development of technologies that can help in increasing productivity in perpetuity without causing an associated ecological harm.He also stated that to achieve the goal of food security by ending hunger and to promote sustainable agriculture, it is important that in the field of social protection as well as the scientific measures needed for achieving food and nutrition security, we should move from the green to an ‘evergreen revolution’ approach.
The Evergreen Revolution technologies are based on a farming systems approach and will also involve farmer participatory breeding and knowledge management. Nation’s agricultural research and technology development system should be strengthened and reoriented to play the pivotal role in creating a science-based and knowledge-led evergreen revolution. A sustainable evergreen revolution enhances the quality of life of farm families and revitalizes rural communities. Taking good care of both human and environmental resources is the heart of a sustainable agriculture
Use of biotechnological tools in agriculture could make food crops high yielding and more robust to biotic and abiotic stresses. This could stabilize and increase food supplies, which is important against the background of increasing food demand, climate change and land and water scarcity.
Nanotechnology can be used in agriculture in many ways. It can help in promoting soil fertility and balanced crop nutrition; effective weed control; enhancing seed emergence using carbon nanotubes; delivery of agriculture chemicals, field-sensing systems to monitor the environmental stresses and crop conditions and improvement of plant traits against environmental stresses and diseases.
Rainbow revolution concept is a combination of Green Revolution, White Revolution, Blue Revolution, Yellow Revolution and Brown Revolution. It was after these revolutions, the Indian agriculture slowly shifted from traditional behaviour to scientific behaviour.
The various colors of the Rainbow Revolution indicate various farm practices such as Green Revolution (Foodgrains), White Revolution (Milk), Yellow Revolution (Oil seeds), Blue Revolution (Fisheries); Golden Revolution (Fruits); Silver Revolution (Eggs), Round Revolution (Potato), Pink Revolution (Meat), Grey Revolution (Fertilizers) and so on.
