In recent years, the word intersectionality has become a buzzword in many different academic disciplines from public health to environmental sustainability to education. The concept of intersectionality is actually quite self-explanatory. Within the context of international development, intersectionality is the idea that you cannot address development issues as stand-alone issues, because sustainable development is intertwined and what occurs in one area can have effects on other areas. There are both positive and negative examples of this. For example, if a person receives a quality education, this could also have positive outcomes for their economic status, their future employment, their health, and other factors. Similarly, if someone is struggling with extreme poverty, this may have ramifications for their education, health, and access to decent work. All aspects of sustainable development are interrelated which is why it is important to look at development comprehensively rather than as individual issues. This is why it is important to look at all 17 Sustainability Development Goals as a set rather than 17 individual goals. The success and progress of each goal effects the others, so for sustainable development to be successful, it is critical to understand how different aspects of development effect one another.
Another important aspect of intersectionality in the sustainable development field is the collaborative efforts between many different stakeholders to achieve goals. For example, one of the important aspects of urban sustainable development going forward is the idea and implementation of smart cities. This is discussed in the New Urban Agenda developed at Habitat III and Sustainable Development Goal 11: Sustainable Cities and Communities. Creating smart cities needs a combination of information and communication technologies (ICTs), urban planning, clean energy, infrastructure, and most importantly, the people who live there. The intersectionality between all of these sectors is what makes smart cities possible. I think that international actors and sustainable development stakeholders have successfully understood the importance of intersectionality in the sustainable development field, with the SDGs as a wonderful example. The SDGs predecessor, the Millennium Development Goals, did not have the same understanding of the intersectionality between the 8 different goals, which is one reason I think the SDGs will have more success in achieving their goals compared to the MDGs. I am hopeful that with the continued focus on intersectionality in sustainable development, we will continue to see improvements and successes around the world.
