Allocation of dynamic inductive charging infrastructures on airport aprons

Abstract:

In the attempt to reduce the CO2 footprint of the aviation sector, airport ground vehicles such as passenger buses are increasingly being electrified, hence requiring potentially large batteries and charging stations as well as long charging downtimes. As a technological alternative to conductive charging of those vehicles, we consider the dynamic inductive charging technology, with which the vehicle's batteries can be charged wirelessly while the vehicle is in motion. The features of the airport aprons and their special traffic flows make this technology particularly attractive. However, if this technology were to be used, a difficult spatial allocation problem of its technical components would have to be solved. We describe this strategic planning task, develop alternative models to represent the underlying allocation problem and report numerical results on the solvability of the different modeling variants and the performance of a specific heuristic algorithm.

Planning marine protected areas under the CCAMLR regime: The case of the Weddell Sea

 

Abstract:

The Global Biodiversity Framework sets an ambitious "30×30" conservation target, aiming to protect 30% of the Earth’s land and sea through designated protected areas. However, we're still falling short, with ocean protection currently at just 8.2%. Most existing marine protected areas (MPAs) are small-scale and primarily within national jurisdictions, leaving much work to be done. In international waters, several initiatives are underway to establish large-scale MPAs, particularly in the Southern Ocean under the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

One of these initiatives is the Weddell Sea MPA Phase 1 (WSMPA P1), initiated in 2013 and spearheaded by Germany under the EU's leadership. The WSMPA P1 aims to conserve one of the world’s last pristine marine areas, known for its vulnerable ecosystems and unique biodiversity, while also serving as a tool for enhancing the region's resilience to climate change. Over the years, the WSMPA P1 proposal has garnered "best science currently available" endorsements from the CCAMLR Scientific Committee and increasing support from CCAMLR Member States. By 2023, ten co-sponsors had backed the EU's proposal, but unanimous adoption remains elusive, with some member states opposing the need for MPAs.

In presenting the WSMPA P1 initiative, I will walk through the planning steps involved in developing an MPA in the high seas of the Southern Ocean under the CCAMLR regime. At the end of my talk, I will provide an outlook on the current situation regarding the establishment of CCAMLR MPAs and show that best scientific practices may not be sufficient to achieve the consensus and political momentum ultimately required for the designation of MPAs in the Southern Ocean.
