Kerala Science Congress, an annual event that has been organised for the last 30 years at different districts across the state, is an academic platform for young researchers and senior researchers alike, for sharing and exchanging their scientific achievements and knowledge. As in every year, this year’s Kerala Science Congress is organised based on a focal theme “Our environment- Our future: Science and Technology for Rebuilding Kerala”. The theme is utmost relevant considering the difficult phase that the State faced a few months ago. Many experts in this theme subject will deliver talk, discuss and share their expertise on various aspects of the theme. Science Congress will also have paper and poster presentations in 12 different subject areas which include: Agriculture & Food Sciences, Biotechnology, Chemical Sciences, Earth & Planetary Sciences, Engineering & Technology, Environmental Sciences, Forestry & Wild Life, Fisheries & Veterinary Sciences, Health Science, Life Sciences, Mathematical & Statistical Sciences, Physical Sciences and Science Education, Communication & Society. There will be a leading talk by eminent scientists before the beginning of the presentation in each subject area. In addition to these other attractions of Science Congress are: Children’s Science Congress and Post Graduate students’ interactive session. While children’s science congress gives a platform for the budding scientists to showcase their talents, the post graduate students’ interactive session gives upcoming researchers a great opportunity to interact with eminent scientists in various disciplines. I have great pleasure in presenting the abstract volume of the 31st Kerala Science Congress to the scientific community. I take this opportunity to thank all those who contributed scientific papers as well as the Chairmen and experts for their sincere effort in reviewing and selecting the papers for presentation. This year KSCSTE is organising the Kerala Science Congress jointly with KSCSTE-Jawaharlal Nehru Tropical Botanical Garden & Research Institute and Fatima Mata National College, Kollam. I wish to congratulate and express my deep sense of gratitude to all the people involved in making Kerala Science Congress a great event. Dr. S.
