Restoration of Cymodocea nodosa (Uchria) Ascherson seagrass prairies through seed propagation. Germination in vitro, plantlet acclimation and transplanting to natural meadows.

[EN] The seagrass Cymodocea nodosa (Ucria) Ascherson is the most abundant seagrass species in the Canary Islands (Spain), where it forms dense submerged, ecologically relevant communities as stable and protected habitats. As with other seagrasses, concern has arisen due to a decline in the number and extension of the communities as the result of adverse activities in coastal areas. Seed germination and planting are assumed as cost-effective method for restoration. In the frame of the restoration of natural populations of Cymodocea nodosa, pilot experiences not tested so far in the Canary Islands have been carried out to developed in vitro techniques to produce viable seedlings and its transference to the natural environment.

Petroleum development and climate change: Risks of being a host country

[EN]A petroleum expert’s view on risks and benefits of oil exploration today in Canarias, considering the climate change facts. The talk starts with an overview of the total petroleum development process, from exploration to post-abandonment, indicating some important risks and benefits for each, from a petroleum industry and a personal perspective. Then there is a part of the talk about the agreed facts of climate change, and what this means for us all. The end of the talk brings together these two sections in a summary.
