Different aspects of the development process have been emphasized by the many scholars and observers who have ventured into this field. The seminal work of Sen (1999) identifies freedom as both the primary end and principal means of development. The Brundtland Commission stressed that development must involve the care and nurturing of the environment for future generations. Others have focused particularly on poverty reduction and the empowerment of poor people. All these approaches consider economic growth a vital component of the development process, while emphasizing that development is about more than growth.
