Biodiversity, a complex topic covering aspects of biological variation, includes a range of living beings, the relationship among them and with the physical environment; and the sum total of their genetic make up. It encompasses species, ecosystems, and landscape diversity. Biodiversity changes through selective adjustments, from small biological variations, genetic mutations to ecosystem changes and results in novel behaviour among species, and societies.
Living systems evolve naturally, ensuring system sustainability. Elimination, or modification of any component of a living system, requires a system readjustment. Predicting the change in a scenario where one species disappears, or a physical component changes is difficult. Biodiversity utilisation processes since ancient times, have given rise to complex management systems through long processes of trial and error - as such human societies derive means of their existence from such systems. Traditional knowledge based systems, is often well adapted to...
