Climate change, renewable energy and nitrogen remediation are just a few of the topics slated for discussion at the third Martha’s Vineyard Coastal Conference next week.

Held every two years, the free daylong conference will take place on Wednesday, June 6 at the Harbor View Hotel in Edgartown. Registration is available online beforehand or on the day of the event, beginning at 9:30 a.m. The keynote address begins at 10 a.m. Several half-hour morning sessions cover shore erosion and sea level rise. The afternoon schedule moves to more in-depth sessions ranging from wind energy to coastal preservation.

The conference ends at 5 p.m. and include a break for lunch.

The speaker lineup includes leading coastal scientists and representatives from a wide array of Island environmental groups and towns. Jeff Donnelly, a senior geologist at the Wood’s Hole Oceanographic Institution, will give the keynote presentation on how climate change, particularly hurricanes, affects coastal population growth.

“Three main focuses are coastal resiliency, water quality and renewable energy,” said Oak Bluffs conservation agent Elizabeth Durkee, who is a moderator and presenter at the conference.

The event is organized by Coastal Zone Management (CZM) and the Woods Hole Sea Grant program, with assistance from Barnstable County and the Martha’s Vineyard Commission.

Kathleen Theoharides, assistant secretary of climate change for Massachusetts, will provide an overview of the Massachusetts Municipal Vulnerability Preparedness Program. The program allows Island towns to develop resilience strategies in the face of climate change. West Tisbury and Chilmark town representatives and community members workshopped the program earlier this month after receiving a MVP grant. Mrs. Durkee said Oak Bluffs has also recently been accepted into the program, and Edgartown and Vineyard Haven have applied.

“The impacts of climate change aren’t something happening in the future, they’re happening now,” Mrs. Durkee said. “We need to address coastal concerns.”

Wind energy is also a topic, and representatives from Vineyard Wind and Deepwater Wind will give a talk on their wind farm projects. Earlier this week, Vineyard Wind won the right to negotiate a 20-year contract to build an 800-megawatt wind farm south of the Island. Deepwater Wind will give an overview of its Block Island wind farm in Rhode Island, the first commercial offshore wind farm in the United States.

A session on using phragmites to lower nitrogen levels and improve water quality in coastal ponds will be led by Emma Green-Beach of the Martha’s Vineyard Shellfish Group. The talk will expand on findings presented by the group in March showing positive signs that phragmites can be an effective nitrogen reduction tool.

The day will wrap up with a panel discussion moderated by Mrs. Durkee with representatives from the MVC, Vineyard Conservation Society, CZM and the Wampanoag Tribe of Gay Head (Aquinnah). Mrs. Durkee said the panel will focus on critical coastal issues facing the Island now and in the coming years. She added that she hopes people will leave the conference with an understanding of the urgency of Island coastal protection, and how Island groups are taking action.

“The main thing is educating the community about the issues facing our coast,” Mrs. Durkee said. “That’s the first step in taking action. We need to understand what’s going on before we can make informed decisions.”
