What 'development' according to the un charter

Development is one of the fundamental principles of the UN and it is explicit in the UN charter in Article 55, for example. The concept of development embodies the goal of improving quality of life whether economically or socially.

Explanation:

The UN Charter is a treaty signed in 1945 that brought the United Nations into existence. It explains the rights and obligations of the countries that are members of the organization and it describes what the main components and different processes and procedures of the organization will be. Among the basic principles are sovereignty and equality among member states.  Underscoring many of the intents described in the charter is the notion of development. Development is a broad concept used to describe the goal of attaining a higher quality of life for all people across the globe. This entails economic development and social development as well as environmental protections that assure that development efforts are sustainable and beneficial to society. Development continues to be one of the fundamental principles of the United Nations as embodied in the 2030 Sustainable Development Goals urging action to mitigate climate change and reduce poor quality of life indicators like maternal mortality.
