The term francophonie first appeared in 1880. It was the French geographer Onésime Reclus who used it to designate the geographical areas where the French language was spoken. The Francophonie, also called the French-speaking world or the French-speaking space, refers to the group of people and institutions that use French as their primary language of socialization, language of use, administrative language, language of instruction or language of choice. The Commonwealth is an intergovernmental organization composed of 54 member states, almost all of which are former territories of the British Empire. Sustainable development is part of the IOF's mission and official development assistance is a motivation for many developing countries that are members of the IOF. Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This book aims to provide an overview of the Francophonie, the Commonwealth, ODA and sustainable development.
