Learn about sustainable biomass production in tropical regions in this lecture from Professor Toshiaki Umezawa of Kyoto University's Research Institute for Sustainable Humanosphere. Explore the challenges and solutions for converting degraded grasslands left after tropical forest clearing into productive biomass cultivation areas. Discover how international collaboration between Indonesia and Japan is advancing sustainable biomass production systems despite the COVID-19 pandemic. Through four comprehensive sections, examine the fundamentals of biomass, background context, sustainable production methods in tropical degraded grasslands, and the future of biomass utilization in post-pandemic society. Gain insights into how this research aims to create mutually beneficial outcomes for both resource-producing and importing countries while addressing critical environmental challenges.
