Carbon footprint of reservoirs – lessons learned from tropical systems
Reservoirs play key social and economic roles as source of water and hydropower. There are currently about 38,000 dams around the world and many new ones are planned especially in the tropics, affecting landscape-scale greenhouse gas emissions and the carbon cycle. Particularly methane emission is of major concern, since the transformation of previously fixed atmospheric carbon dioxide to methane implies a 34-fold amplification in global warming potential.
However, reservoirs also trap large amounts of fluvial sediments containing organic carbon in a burial-prone environment, thereby enhancing basin-scale organic carbon sequestration. In my talk, I will discuss some of the latest advances towards quantifying the carbon footprint of reservoirs, showing the research that my group has developed over the past years. We have demonstrated, for example, that reservoirs sequester terrestrial organic carbon with higher efficiency than other depositional environments. We also confirmed that methane emission through bubbles, an emission pathway largely overlooked, can account for most of a reservoir greenhouse gas emission. It is clear that the ultimate carbon footprint of a reservoir is strongly dependent on the characteristics of its project and on the properties of its catchment. Based on this, I will also discuss ideas of how strategic dam planning can reduce greenhouse gas emission.

Estamos nostálgicos recordando el Congreso #Limnologia2020 y os compartimos el vídeo de la Cuadrilla de Tallante y Las Palas con el que os dimos la bienvenida!!
Muy agradecido a toda la organización de @limnologia2020 por la genial organización de este congreso y por el premio que han concedido a mi comunicación: "Avances en ecología de metacomunidades
en ríos intermitentes para la mejora de su conservación y gestión".
I am very happy to have received an accesit for the best poster of the Congress @limnologia2020. My poster was presented in the SS2 which focused on the nitrogen cycle in both human and natural processes. It was a pleasure to share the experience with the rest of the N-geeks! 2
Congratulations to @AIL_limnologia and @limnologia2020 for their first virtual meeting!!!!!! Good to see Iberian Limnologists connected!!! https://twitter.com/AIL_limnologia/status/1321888095835463687
Amazing talks, 283 participants, 21 countries, high diversity of topics, gender-balance, smiles everywhere and plenty of great science around limnology.
We close our 1st virtual meeting with great success. Thanks everybody. Thanks the Organizing Committee for the enormous effort!
Super proud of my PhD student @DianaSGraca for winning the prize for best poster presentation at @limnologia2020 conference this week! Congrats! 🤗🎉
