I'd like to start by thanking you for involving me in this major world-class scientific event. I was delighted to be able to present at this conference some results from my country (Côte d'Ivoire) in hydrological and environmental science in relation to deforestation and climate variability. On the whole, the scientific content of the conference was of a high standard and, for my part, a remarkable success. To deal specifically with the 3 points submitted for my opinion, I would say: 1) The scientific quality of the lectures was very acceptable and instructive for the scientific world; 2) It helped me in that I learnt certain scientific concepts in earth sciences and climate change that could lead me to improve certain aspects of my teaching profession; 3) Peers Alley Media, Canada did a good job of selecting the speakers for the discussion sessions at this event. The speakers showed their professionalism and were all talented. I would like to congratulate you warmly on the excellent organization of the conference. You never failed to send messages to the participants. When it took us a day or two to get back to you, you got back to us. Even on the day of the presentations, you made sure that all the speakers logged on at least 30 minutes before their presentations. This magnificent organization ensured that everything ran smoothly and, above all, on time. I really enjoyed it. Well done to you all.
