Research on the destinations of environmentally induced migrants has found simultaneous migration to both nearby and long-distance destinations, most likely caused by the comingling of evacuee and permanent migrant data. Using a unique data set of separate evacuee and migration destinations, we compare and contrast the pre-, peri-, and post-disaster migration systems of permanent migrants and temporary evacuees of the Great East Japan Earthquake and Tsunami. We construct and compare prefecture-to-prefecture migration matrices for Japanese prefectures to investigate the similarity of migration systems. We find evidence supporting the presence of two separate migration systems—one for evacuees, who seem to emphasize short distance migration, and one for more permanent migrants, who emphasize migration to destinations with preexisting ties. Additionally, our results show that permanent migration in the peri- and post-periods is largely identical to the preexisting migration system. Our results demonstrate stability in migration systems concerning migration after a major environmental event.
This study discusses the history, transitions, governance, and planning of an ethnic urban neighborhood, as exemplified by San Francisco's Japantown in the United States. It presents a variety of challenges in urban ethnic neighborhood governance, including gentrification, redevelopment, heritage preservation, and the participatory public planning process. In response to economic neoliberalization, recent urban planning policies have inspired a diverse network of urban actors, including individuals, private corporations, and nonprofit community organizations to banded together to preserve their community's cultural heritage in the face of market-driven redevelopment and perceived gentrification. In San Francisco, recent movements have aimed to preserve the ethnic and cultural heritage of the city's Japantown. While the community has nurtured and been enriched by many different cultural and ethnic groups, San Francisco's Japantown has historically been represented by primarily Japanese American community organizers and postwar Shin Issei first-generation Japanese immigrants business owners and residents, marking it as a culturally diverse space. However, partly because of this diversity, recent community discussions on preserving Japantown have been divisive. While the general agreement is that the neighborhood's heritage should be preserved, many disagree as to how to balance preservation efforts with economic revitalization to ensure the community's sustainability. Using interviews and field observation, this study analyzes the strengths and challenges of one such movement, the Japantown Better Neighborhood Plan. Analysis of the campaign's implementation reveals the strengths and weaknesses of the plan and makes recommendations for future community governance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
