Speech Title: Crop Plants: origin, diversity and global interdependence

Abstract: Crop plants are cultivated plants, fungi and algae which are harvested for meeting the demand of our food, fodder, medicine, cloth, biofuel and other commodities used in our daily life. The concept first emerged in 1935 when Russian plant explorer Nikolai Vavilov proposed that the crop plants originated in areas of the world where they showed their greatest diversity and the farmers would have been selecting different types from their wild stocks for domestication and farming. Vavilov listed the wild relatives of crop plants as 151, belonging to 8 different areas of the world, the so called 8 centre of origin of crop plants. In the world, some 250000 plant species have so far been described of which 75000 provide edible products and 2000-3000 has been subjects of domestication. Prior to agriculture, food acquisition by humans depended on hunting game animals and gathering wild plants by the so called ‘Hunter Gatherers’. Agriculture is fairly a recent practice in the evolution of humankind and not older than 10 000 years. It spreads relatively quickly over the entire world and is now practiced on the five major continents. The diversity of crop plants took a historic turn via modern agriculture. Almost all the countries of the world have become interdependent in terms of crop plants. Our food supply, in a full extent is globalized. For example, chili peppers (Capsicum annuum L.) and tomatoes (Lycopersicum esculentum Mill.), despite being their use in respective local foods of different countries, actually originated in South America. Greater than two-thirds of the crops that are used in national food items of many countries originally came from somewhere else of the world. The trend has accelerated over the past 50 years, making our entire food system completely global. Global interdependency of crop plants intervened by global facts like population increase, food security, climate change and genetic erosion are discussed.
