      Water system construction continues:
      http://www.tristandc.com/watersupply.php

      The pumping station is quite sophisticated and seems to have been done
      using the regular public works crew, advised by one foreign technician,
      and leaving behind islanders with new skills who understand the system
      and can diagnose problems when (not if) they arise. This is a good
      thing.

      Those who decide such things seem to believe that a similar concept
      isn't applicable to a hospital or even a new harbour. Since building a
      new harbour DFID's way would cost £48 million, the sustainability of
      the entire community and its lovely new water system sit on the brink
      of sudden disaster.

      We see they are using gabion walls. Before the invention of concrete,
      in perhaps 1200 BC, and ready mix trucks somewhat more recently,
      retaining walls were sometimes made of gabions, which are wire baskets
      filled with stones. Their failure rate depends on the failure of the
      wire, not the stones. The wire is usually steel, sometimes galvanised,
      and rarely, stainless steel.

      Gabion retaining walls on steep slopes are usually sloped or stepped,
      so that when (not if) they fail, they will mostly remain where they
      are and continue doing their job. Those designed in the UK by budget
      conscious DFID contractors are stacked vertically. They are easier to
      build by what are thought to be us "primitive natives" out here in the
      Overseas Territories, and they won't fail until after the designer has
      retired.

      South Atlantic Overseas Territories Regional Workshop Report
      from JNCC Communications & Governance Adviser Maddy Long
      on 20th June 2014

      This week on Ascension Island experts from across the UK Overseas Territories in the South Atlantic
      attended a regional workshop which was co-hosted by the Ascension Island Government and the Joint
      Nature Conservation Committee (JNCC). The workshop brought together delegates from the region to
      share all aspects of conservation expertise and experience, exploring opportunities for co-operation
      in Sustainable fisheries, Marine Protected Areas, biodiversity action planning, and seabird monitoring.

      Fisheries managers from the Falklands, South Georgia and Tristan da Cunha presented case studies on
      sustainable fishing practices, highlighted lessons learnt and discussed best practice in the areas
      of enforcement, licensing and fisheries science. These were followed by a range of presentations and
      discussions where real opportunities to share expertise, equipment, and skills were explored.

      The thirty workshop participants included Ascension Island Councillors, the Ascension Island
      Administrator, Directors of Fisheries from South Georgia, Ascension and Tristan da Cunha, fisheries
      experts from the Falklands, St. Helena, the Foreign and Commonwealth Office, the Centre for
      Environment, Fisheries and Aquaculture Science (Cefas), the Royal Society for the Protection of
      Birds (RSPB) and JNCC.

      James Glass, the Director of Fisheries on Tristan da Cunha who had been travelling since the end of
      May to attend the workshop, presented an overview of the fishery on Tristan and highlighted ‘this is
      the first ever regional workshop that has focussed on fisheries and the marine environment. It is a
      wonderful opportunity to share information, expertise and ideas with fellow islanders from the South
      Atlantic’
