Many refugee camps exist for decades but associated infrastructure needs are only planned for the very short term, including provision of power. This study advocates a shift in approach to sustainable electrification of essential services in refugee camps for lighting, refrigeration, health, water, education, alongside camp operations. Qualitative and quantitative surveys were conducted in refugee camps in Uganda and Bangladesh which assessed the electrical supply needs across such categories.

Article Synopsis
  • * The case study highlights the coordinated efforts of various agencies in areas such as testing, community outreach, quarantine management, and staff education during the first six months of the pandemic.
  • * The "whole of system" approach proved effective, reducing community anxiety and promoting the significance of virtual care, ultimately demonstrating the need for a well-integrated public health system.

Article Synopsis
  • Australia effectively managed COVID-19 transmission through the Sydney Local Health District (SLHD), which applied a "whole of health" integrated approach focusing on community care.
  • A qualitative study involved interviews with 20 key informants, revealing that strong governance, emergency preparedness, and a flexible workforce contributed to SLHD's success.
  • The pre-existing interagency relationships allowed for swift integration of services and innovative solutions, enabling the district to reach marginalized populations and reduce community transmission efficiently.

A validated numerical model of tidal flows and sediment transport around the Alderney South Banks was used to investigate the potential effects of large (300 MW) tidal turbine arrays at different locations in Alderney territorial waters. Two methods were used, firstly looking at hydrodynamic changes only and secondly modelling sediment transport over a non-erodible bed. The baseline hydrodynamic model was validated relative to ADCP velocity data collected in the immediate vicinity of the sandbank.

This research provides an updated energy yield assessment for a large tidal stream turbine array in the Alderney Race. The original array energy yield estimate was presented in 2004. Enhancements to this original work are made through the use of a validated two-dimensional hydrodynamic model, enabling the resolution of flow modelling to be improved and the impacts of array blockage to be quantified.
