As with previous editions, the cluster meeting is known for uplifting the future of the research fields by encouraging scientists and fellow researchers to present their work through oral speeches and poster presentations. Hot topics on genetics and sustainable development were hotly discussed and exchanged by presenters and visitors in the three-day’s diversified program. Conference organizers took the privilege of felicitating Keynote Speakers, Chair and Co-Chairs whose support made conference a great success and also thank all other attendees who contributed a lot for the smooth functioning of the Event. 

Before and after the conference, we received warm support and valuable suggestions from the delegates on how to better plan and organize the next conference. With the enormous feedback from the participants and supporters, the organizing committee is currently bringing forth “WDD-2025” scheduled to be held during April 23-25 in Nara, Japan. We look forward to meeting you all next year.
