Shoreline Protection in the Republic of the Marshall Islands

I’ve had a very productive week here on Majuro, the principal island in the Republic of the Marshall Islands. Our longtime collaborator Lyon Associates invited us to join their team for a Sea Grant project focused on developing a suite of  best practices for shoreline protection around the Marshalls, where land uses range from dense urban in downtown Uliga to rural in Laura, at the other end of the long island.

Really, this is a capacity building exercise focused on increasing efficiency and reliability of small-scale projects implemented by homeowners, who are getting specialty advice from contractors and regulators about appropriate and affordable shoreline protection.  There are a lot of stakeholders with different interests and a huge range of site and wave loading conditions, the perfect conditions for high-quality consulting. It’s gratifying to be working on such an important project.

I’ve been struck by how much of urban Majuro is already protected by well-built shoreline protection. Keeping tide and waves out of dwellings and off of city streets is plainly an important priority that lays claim to a significant fraction of limited local resources.  And while many lots have stabilized shoreline, some have not yet been addressed.  From infill seawalls (below) to increased setbacks and soft beach-sand berms, we’re hopeful that we can develop a useful set of best practices that facilitate safe and comfortable life on this low-lying atoll.
