Flor de Mayo González Miranda
Latin America & the Caribbean
Environmental engineering
Lecturer and researcher,
Faculty of Engineering
San Carlos University
Guatemala City, Guatemala

Dr. Flor de Mayo González Miranda is trying to engineer better landslide prevention for vulnerable areas in Guatemala. Climate change is causing increasingly strong periods of rain in the country, where much of the terrain is rugged. Due to poverty and the lack of government and private programmes for decent housing, many people live in settlements on the slopes of ravines, where rain and other events make landslides more frequent. Landslides obstruct roads and sometimes bury entire communities. Dr. González Miranda is investigating how a specific grass in the vetiver family, Chrysopogon Zizaniodes, can help to prevent landslides. Through soil tests, X-ray diffraction, and other techniques, she has shown how the plants' roots alter the chemical, physical and mechanical behavior of the soil, reducing the speed of soil infiltration as well as soil plasticity. In addition to this work, Dr. González Miranda has also studied the flow of fresh water into Guatemala's ports, and the thermal behavior of sand sericite as a precursor to mullite material.

Dr. González Miranda earned a certification as a production control technician from Rafael Landivar University in 1986, and a Bachelor's degree from San Carlos University in 2002 in industrial engineering. She holds two Master's degrees in environmental science, from San Carlos University (2008) and Cadiz University in Spain (2009). She has worked as an engineer in various capacities, including as an environmental adviser for the company Superingenieria. In 2019, she earned her PhD in industrial and environmental engineering from the University of Almería (Spain). She is currently a researcher and lecturer in the School of Industrial Mechanics at San Carlos University.

Dr. González Miranda is very active in public outreach, training, and awareness raising. She has collaborated with the National Council of Science and Technology and the Ministry of Education of Guatemala on the TIC-STEAM project to provide training in programming, robotics and environmental care to girls in rural areas, and has conducted free trainings for women, youth and community leaders on manufacturing simple products, safety and industrial hygiene, and best practices for manufacturing, among other topics. She has also been interviewed in the newspaper Prensa Libre to provide expert analysis on Guatemala's multi-million dollar Chimaltenango Bypass, which gave rise to a corruption case related to the project. She is the author of six books published in Guatemala.

Myriam Mujawamariya
Tropical forest ecology and ecophysiology
Department of Biology
University of Rwanda
Kigali, Rwanda

Dr. Myriam Mujawamariya is helping Rwanda to prepare for climate change by studying how various types of indigenous trees respond to different climate scenarios. Erosion is a major environmental concern in Rwanda, and many efforts are being put into landscape restoration and ecosystem-based adaptation. However, greater knowledge is needed about how trees will respond to higher temperatures and other climatic changes, as well as which trees can best support ecosystem services such as soil stabilization, climate regulation, biodiversity, and bioenergy. Dr. Mujawamariya tested the physiological responses of 20 native species grown at three sites along an elevation gradient, to simulate different climate change scenarios, using the unique Rwanda Tropical Elevation Experiment, Rwanda TREE project (see The project will contribute to understanding of how climate change will influence tropical forest cover, carbon sequestration and biodiversity not only in Rwanda, but in all of Africa's Western Rift Valley region and beyond.

Dr. Mujawamariya received her bachelor's degree in biology at the former National University of Rwanda in 2007, and a master's degree in plant sciences, specializing in natural resources management, from Wageningen University in the Netherlands in 2012. She received her PhD in natural sciences, specializing in environmental science, from the University of Gothenburg, Sweden in 2021. She began working at the University of Rwanda in 2007 as as a Tutorial Assistant, and then Assistant Lecturer since 2013; in 2021, she was promoted to Lecturer.

Dr. Mujawamariya is a member of the Association for Tropical Biology and Conservation and is a Research Associate at the Center of Excellence in Biodiversity and Natural Resources Management (CoEB). She has won numerous grants for her work, including the Belgian ARES grant, and grants from the Rwanda National Council of Science and Technology, the Swedish International Development Cooperation Agency (Sida). She has participated in many community outreach activities through the University of Rwanda and CoEB to raise awareness for biodiversity conservation, including educating school children about environmental protection.

Ashani Savinda Ranathunga
Asia and the Pacific 
Geotechnical engineering
Department of Civil Engineering
University of Moratuwa
Moratuwa, Sri Lanka

Dr. Ashani Savinda Ranathunga is focused on turning industrial and agricultural waste into anthropogenic (man-made) soil for geotechnical engineering-related applications. She is a proponent of the “waste to wealth” concept, which is to produce green and value-added products from waste for sustainable and greener applications. Her research findings enable the effective utilization of locally available waste ase secondary raw materials for economical and ecofriendly construction and development projects. Specifially, she is using industrial waste products like fly ash and calcium carbide residues, and agricultural waste products like paddy husk ash and corn cob ash, to stabilize soft soil that is otherwise too weak for construction, contributing to greater longevity of infrastructure. She is also using the same waste products to rehabilitate degraded land and soil in abandoned mines, reducing environmental pollution and adverse social impacts. In addition, she looks at the effective utilization of shallow geothermal resources for energy production in rural areas of Sri Lanka.

Dr. Ranathunga completed her undergraduate degree in civil and environmental engineering at the University of Ruhuna in 2013, graduating at the top of her class. She received her PhD from Monash University, Australia in 2017, where she won the best PhD thesis award and the postgraduate publication award for her work on enhancing extraction of coal bed methane from deep underground coal seams by injecting CO2. Her findings demonstrated the opportunities of using low-rank coal for CO2-Enhanced Coal Bed Methane (CO2-ECBM). After completing her PhD, she joined the University of Moratuwa as a Lecturer attached to the Department of Civil Engineering.

In addition to her research, Dr. Ranathunga supervises both undergraduate and postgraduate students. She has won several awards including the Outstanding Research award from her university. In recognition of her contribution to the field of geotechnical engineering, she was awarded the Bright Spark Lecture Award for most promising young geotechnical engineer/academic by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 2020. Dr. Ranathunga has published around 40 publications including book chapters, indexed journal articles and international conference papers to disseminate knowledge in the field of geo-energy and geo-resources.
