Pollinator declines and dependence on insect pollination, particularly in fruit and vegetable crops, creates a pressing need to understand growers' interactions with pollinators and factors affecting pollination strategies. At present, many growers are dependent on commercial honey bees (Apis mellifera), but diversified strategies may be necessary to secure adequate crop pollination in the future. As of yet, little social science research exists on pollination practices. This article presents the results of a survey of lowbush blueberry growers in Maine. The survey was part of a five-year pollination security study focusing on four fruit and vegetables crops in the Northeast US. The survey assesses grower perceptions of native pollinators' effectiveness and their perceptions of native pollinators' contribution to fruit set. Results indicate a widespread perception among growers of native pollinators' importance. While native pollinators are not effective enough to replace rented honey bees for three-quarters of the industry, they are broadly seen as an important form of insurance in poor weather when honey bees' effectiveness is reduced. The main obstacle to greater utilization of native pollinators found in this study was uncertainty over native pollinators' contribution to yield and the associated difficulty monitoring native pollinators' population size. Scientists and extension experts must work to reduce these obstacles before more widespread use of native pollinators will occur.

Maine hosts numerous rural fishing villages that contribute greatly to the State's economy and culture. The cumulative effects of fisheries regulation, stock depletion, amenity migration and rural restructuring have impacted these communities in complex ways. Drawing on ethnographic research, interviews, and secondary data we have identified the patterns of change as symptomatic of gentrification, and we have investigated how these changes are affecting the communities' vulnerability and resilience. Gentrification of coastal property by amenity migrants is responsible for the displacement of community members, including fishermen. The loss-of-access to the waterfront has increased their sensitivity to future threats. Further changes in the demographics and economies of the communities have increased social and cultural conflicts. Nevertheless, this paper also demonstrates that gentrification can increase the resilience of the community. Amenity migrants have the capacity and desire to provide social and philanthropic support, and rural restructuring introduces new economic opportunities and sources of revenue. The underlying consequences of gentrification are difficult to discern from secondary data alone, and we argue that the ethnographic approach is crucial. Through interview responses we have identified an identity crisis in these communities undergoing gentrification, with many of the conflicts over the future importance of fishing to the community.

Aquaculture is the global food system's fastest growing sector. The postproductive transition-the shift away from commodity production toward more consumption-oriented land uses-is common in many coastal areas as well. This paper examines the intersection of these trends in a U.S. state, Maine, with expanding aquaculture and extensive coastal, rural economic and demographic change. It examines interactions between coastal landowners and aquaculture farmers at aquaculture lease hearings in the state's three main aquaculture regions. Landowners are often uncertain about aquaculture because it is new and unfamiliar. Farmers use lease hearings to educate coastal landowners about farm operations, and farmers respond to concerns by altering their operations to fit landowners' priorities. However, comparative analysis of the three regions reveals divergent histories and geographies leading to different levels of conflict. This study shows the value of applying rural postproductive transition theory to coastal regions and aquaculture development.

Pollinator conservation efforts and growing interest in wild bee pollination have increased markedly in the last decade, making it increasingly important to have clear and practical estimates of the value of pollinators to agriculture. We used agricultural statistics, socio-economic producer surveys, and agronomic field research data to estimate traditional pollination value metrics and create novel approaches to the valuation of the ecosystem services provided by wild pollinators. Using two regionally important United States (USA) crops—Maine wild blueberry and Massachusetts cranberry—as models, we present the perceived values of wild bee pollinators from the perspectives of both consumers and producers. The net income attributable to wild bees was similar for wild blueberry ($613/ha) and cranberry ($689/ha). Marginal profit from incrementally adding more hives per ha was greater from stocking a third/fourth hive for cranberry ($6206/ha) than stocking a ninth/10th hive for wild blueberry ($556/ha), given the greater initial responsiveness of yield, revenue, and profit using rented honey bee hives in cranberry compared with wild blueberry. Both crops’ producers were willing to annually invest only $140–188/ha in wild pollination enhancements on their farms, justifying government financial support. Consumers are willing to pay ≈6.7 times more to support wild bees than producers, which indicates a potential source for market-based subsidies for invertebrate conservation.
