Building Sustainable Cities: Insights from Pichaya Moeller

Pichaya Moeller, World Bank Urban Development Consultant

As Thailand¡¯s cities grow and evolve, the challenge of creating livable, resilient, and inclusive urban spaces has never been more critical. At the forefront of this transformation is Pichaya Moeller, an Urban Development Consultant at the World Bank, who works to shape policies and projects that enhance urban sustainability and infrastructure. In this special International Women¡¯s Day feature, she shares her journey in urban development, the biggest challenges facing Thailand¡¯s cities, and how innovative planning can create greener, smarter, and more inclusive urban spaces.

1. What drew you to the field of urban development, and why is it important for Thailand¡¯s future? 

Urban development is a part of our daily lives. When you look at the challenges in urban development, they cut across various dimensions¡ªsuch as the economy, human capital, and the environment. There is still so much to address in Thailand on these matters, and if I can contribute by supporting from a policy perspective, it could have a positive impact on many citizens across the country.

2. What are some of the key challenges and opportunities in making Thailand¡¯s cities more sustainable?

Thailand¡¯s cities face key challenges such as lack of integrated urban development planning, limited green space, climate risks, and infrastructure strain. A major barrier is limited investment to support sustainable development. To achieve Thailand¡¯s clean energy and broader development goals will require a rapid scale-up in finance¡ªTHB 779 billion (USD 22 billion) is needed for renewable power, and THB 974 billion (USD 28 billion) for energy efficiency across sectors from 2022 to 2037. Despite these challenges, there are strong opportunities through low-carbon intervention, nature-based solutions, and smart city innovations. Cities around the world are making progress on these fronts, and I believe Thailand can adapt and apply these approaches to build more sustainable, resilient urban futures.

3. Can you share a project you¡¯ve worked on that has had a significant impact on urban communities?

One project I worked on that had a meaningful impact on urban communities focused on addressing urban heat¡ªa growing challenge in rapidly developing cities like Bangkok. Urban areas often experience significantly higher temperatures than surrounding rural areas due to densely built environments, limited green spaces, and anthropogenic heat from human activities. This ¡°urban heat island effect¡± affects the livability of everyone in the city.

Through this project, I had the opportunity to collaborate with government agencies, the Bangkok Metropolitan Administration (BMA), medical experts, architects, and think tanks to develop recommendations aimed at improving the city's livability. I hope the insights and lessons from Bangkok can also inspire other cities, both in Thailand and globally, to take action on this pressing issue.

4. What advice would you give to young women interested in shaping the future of cities through urban planning and development?

There are many ways you can contribute to shaping the future of our cities. Everyone can find their place in this important work and make a meaningful impact. Whether it's by learning about urban planning, sharing your ideas during public hearings, or supporting research, every contribution counts. The more you engage with these topics, the more you¡¯ll grow and understand the power of collective action in building better cities for all.

5. Who is a woman that has inspired you in your journey, and why?

I wouldn¡¯t say there¡¯s one particular person, but rather multiple people throughout my career who have inspired me. For example, my sister and my mom have always been supportive and have shown me that anything is possible with full commitment and strong dedication.
