A sustainability assessment framework for regional-scale Integrated Coastal Zone Management (ICZM) incorporating Inclusive Wealth, Satoumi, and ecosystem services science

Sustainability has become an increasingly important concept in the last few decades; however, its operational usefulness has not always been clear. In other words, some sustainability assessments may not provide decision makers with the practical information necessary to perform the assessment. This study proposes a novel operational sustainable assessment framework for Integrated Coastal Zone Management (ICZM) on a regional-scale based on a feasibility study in the Seto Inland Sea in Japan. The framework draws upon three separately developed concepts: Inclusive Wealth as the technical framework for the sustainability indicators; Satoumi (a traditional Japanese multifaceted coastal zone concept); and ecosystem services science. These three concepts complement each other when seeking to corroborate an assessment framework. Indicators based on the framework and relevant to the case study site were identified. Although Satoumi is a traditional Japanese knowledge, it is believed that its application may be instructive for other areas, as similar concepts can be found and utilized for the conduct of ICZM sustainability assessments.

Livestock and Private Tree Holdings in Rural Ethiopia: The Effects of Collective Action Institutions, Tenure Security and Market Access

Abstract This article uses househld panel data spanning the period 2000–2007 to test hypotheses from the literature that secure land tenure, market access and collective action promote accumulation of private capital assets in rural highland Ethiopia. The three natural capital assets analysed in the article, livestock, eucalyptus trees and non-eucalyptus trees on households’ farm plots, make up virtually 100 per cent of privately held disposable assets. Incomes and capital stocks are extremely low and constant and tree assets are at least as important as livestock. We find that collective action and secure land tenure have strong positive effects on accumulation of livestock and other trees, but not eucalyptus. We also find evidence that market access promotes eucalyptus holdings and that other types of wealth tend to be positively associated with private natural capital stocks.

Students’ perceptions of a marine education program at a junior high school in Japan with a specific focus on Satoumi

Abstract In many coastal areas of Japan, local fishermen manage fish and other marine resources in a sustainable manner. Such areas are referred to as Satoumi. In this study, we focused on Hinase Junior High School in Okayama Prefecture, Japan, which is implementing a proactive marine education program in collaboration with local fishermen to maintain Satoumi. We conducted semi-structured interviews with the students (n = 108; thirty-six students in each grade [seventh-, eighth-, and ninth-graders]) at Hinase Junior High School. Using the grounded theory, we identified students’ perceptions of this program as well as of the sea. The results revealed that the program appears to have changed students’ perceptions, such as recognizing the importance of the sea and eelgrass as well as their behavior such that they no longer throw waste into the sea. The higher the grade level was, the more that students felt close to and were willing to care for the sea. Our study suggests that the program has helped to develop individuals who are knowledgeable about the fishing community of Hinase, fishermen’s roles, and activities that would contribute to biodiversity conservation and who are motivated to conserve Satoumi in the future.

Long-term evolution of preferences for conservation projects in the Seto Inland Sea, Japan: a comprehensive analytic framework

Background The long-term evolution of preferences for nature is crucial to conservation projects, given their targeted long-term horizons. Neglecting to account for this evolution could lead to undesirable human–nature relationships. This study compares the willingness to pay (WTP) for three coastal conservation projects in the Seto Inland Sea, Japan, at two distant time points (1998 and 2015), and tests for temporal transferability. It also compares protest responses that are often overlooked in WTP practices, regardless of their utility for conservation projects. Methods Given the lack of a unanimous protocol for protest response analyses and their use in estimating WTP, we propose a comprehensive analytic framework that integrates the two. Results We show that, while preferences for coastal ecosystem services were overall stable and temporarily transferable, the preferences for certain aspects of conservation projects considerably changed. Discussion This suggests the need to reconsider the projects’ scheme, not the ecosystem services themselves, along with the clarification of beneficiaries and those responsible for past destruction. We conclude by suggesting further studies with a focus on regions experiencing significant social-ecological changes, such as developing countries, by exploiting the rich asset of existing valuations. This could contribute to the database for more temporal-sensitive ecosystem service valuations utilized for benefit transfers.
