CONCORD, N.H. — A new report shows New Hampshire lagging behind Maine and Vermont when it comes to the volume of food it produces and the profitability of its farms.

With interest in local food rising, the state Department of Agriculture had researchers at the University of New Hampshire analyze the economic impact of the New Hampshire food system.

The report cites several strengths and opportunities, including a wealthy population strongly interested in the “buy local” movement, and a high percentage of farmers who sell direct to consumers. On the negative side, only 6 percent of the state’s population could be supported by the current level of local agricultural production, compared to about 40 percent in Maine and Vermont.
