It seems like you've made a typo and haven't asked a specific question. However, I can provide a brief overview of the Sustainable Development Goals (SDGs) as part of development theories.

The Sustainable Development Goals (SDGs) are a collection of 17 global goals designed to be a "blueprint to achieve a better and more sustainable future for all". They were set in 2015 by the United Nations General Assembly and are intended to be achieved by the year 2030. These goals cover social and economic development issues including poverty, hunger, health, education, climate change, gender equality, water, sanitation, energy, urbanization, environment and social justice.

Here are the steps to understand the SDGs:

1. Familiarize yourself with each of the 17 goals. Each goal has specific targets to be achieved within the timeframe.

2. Understand the importance of each goal. Each goal addresses a specific issue that is crucial for sustainable development.

3. Learn about the progress of each goal. The UN provides annual progress reports on each goal.

4. Understand the role of various stakeholders. Achieving these goals requires the cooperation of governments, the private sector, civil society, and individuals.

5. Learn about ways to contribute. Everyone can contribute to achieving these goals through actions in their daily lives.

If you have a specific question about the SDGs or development theories, feel free to ask!
