This initiative is one of the winners of the 2020 United Nations Global Climate Action Awards, which aims to highlight some of the best examples of what people around the world are doing to fight climate change.
As a landscape architect, Kotchakorn Voraakhom established the Landprocess and Porous City Network to build innovative landscape solutions for urban resilience in Bangkok. Her firm has equipped the city with public green space and nature-based solutions to increase the city’s resilience, reduce flood risk and improve the well-being of its citizens. For the first time in 30 years of rapid urban development, 11 acres of property in the heart of Bangkok was transformed into a public park.
Opened in 2017, Chulalongkorn Centenary Park is the first critical piece of green infrastructure in Bangkok to reduce urban flood risk. With on-site water management, the park can collect, treat, and hold up to one million gallons of water, alleviating overwhelmed public sewage during heavy rainfall. In addition to being Bangkok’s first park in 30 years, it was also the first city public park led by a female landscape architect.
As climate change causes an increase in sea level rise, storm surges, and unexpectedly heavy rainfall, low-lying cities across the globe are bracing for urban flooding disasters. Bangkok is one of the most at-risk cities from climate impacts and one of the capitals with the least amount of green space in the world.
Explosive development is ignoring the city’s delta landscape and its porosity while eating away canals and agricultural land that once breathed and absorbed water.
To address Bangkok’s vulnerabilities to climate change, Landprocess focuses on increasing carbon-sequestering landscapes such as urban forests, environmental productive parks, green roofs, wetlands, and redesign the waste spaces and infrastructure for concrete cities to return to their natural porosity, increase public health and urban adaptability.

In 2019, Thammasat Urban Rooftop Farm, Asia’s largest, was opened. Landprocess repurposed wasted rooftop space to address food and water scarcity in preparation for future climate challenges. In 2020, Chao Phraya Sky Park was realized. Once an inaccessible and incomplete sky railway, the old ruins are now whole, becoming the first realized bridge park to cross a river in any capital city in the world.
While also helping to recycle and reuse runoff water from surrounding areas, Chulalongkorn Centenary Park is equipped with underground rainwater tanks that collect water to irrigate itself for up to a month in times of drought. Thammasat Urban Rooftop Farm provides a sustainable food system and addresses renewable energy, circular economy, on-site water management, and waste management, all in one inclusive space. Chao Phraya Sky Park is the first bridge park, demonstrating the potential of public space by reusing the abandoned infrastructure, reduce transportation carbon emission by encouraging cycling and walking.
Landprocess helps vulnerable neighborhoods most at-risk of flooding and displacement from rising sea levels better understand climate impacts. Landprocess collaborates with these communities to design solutions to address these challenges, enabling them to successfully put forward their projects for governmental approval and funding. This currently includes 750 households most at-risk of flooding at the Latprao Canal community and 800 others at the Hat-Lek Fishery community who are affected by rising sea levels and 300 households at Bann-Pai who were affected by living in the floodplain.
Through Landprocess’ participatory design process, women--as the main caretakers of the family and first-hand witnesses of issues in their communities--have provided detailed insights and ideas highly useful in creating sustainable designs catered for improving the quality of life and social fabric of their society.
Landscape porosity is a key natural mechanism for survival in times of climate change. Its solutions can help water-based cities like Bangkok and delta cities across South East Asia increase their resilience to climate change.
Landprocess and Porous City Network aim to build many more productive public spaces in dense urban areas, as well as various projects serving thousands of low-income households from the displacement of climate-vulnerable communities in Thailand, and other countries in the region. Partnering with more than 100 young designers from 5 universities, locally and internationally, the core mission is to use the co-creating design process to involve communities and future generations of designers to work hand in hand in building sustainable communities.
Completed projects like the Chulalongkorn Centenary Park and Thammasat Urban Rooftop Farm and Chao Phraya Sky Park serve as models that demonstrate the potential for city-scale implementation of productive green spaces that can provide climate mitigation and adaptation, as well as sustainable food, energy, and economy.
