    <p>In recent years, integrated landscape approaches are gaining attention as an effective policy concept to maintain biodiversity and human well-being in the secondary natural environment. This study ascertained the current status and issues related to recognizing and efforts to implement this concept for Japan's natural environment governance. The study first compared the relationship between this concept and the legal system through a literature review. Following which a questionnaire survey addressed to the Ministry of the Environment, Japan was conducted by the study to analyze the current status and issues related to implementing integrated landscape approaches. As a result, the study found that (1) while this concept has not been widely understood, there are many similar ongoing efforts; (2) there are legal system based efforts and also voluntary efforts as well; and (3) stakeholder participation, consensus building, securing of financial budget and human resources issues are challenges faced for effective implementation. Also, the result indicated additional supports are needed, including strengthening secretariat functions and sharing best practices to promote effective implementation.</p>

    Identifying relatively important ecosystem services beforehand is essential for efficient and effective assessment. Using a best-worst scaling (BWS) method, we investigated the relative importance of cultural ecosystem services (CES) in Japan, where the second phase of national ecosystem service assessment is under consideration. Classifying CES into seven distinct categories (i.e. spiritual and religious values, recreation and tourism, aesthetic values, education and inspiration, social cohesion and sense of place, cultural diversity, and existence and bequest values), we administered a questionnaire survey at the nation-wide scale and collected 28,854 valid BWS responses from 4122 individuals. As a result, BWS successfully elicited the Japanese preferences for CES with completely distinguishable orders, which the conventional rating approach was unable to achieve. Our analysis proposed that future CES assessments in Japan should put more emphasis on aesthetic values as well as existence and bequest values. As we could not find large differences in preferences for these two services across individuals, groups and regions in relative terms, such prioritization could gain broader understanding and supports from wider audiences.

  • Quantitative analysis of national biodiversity strategy and action plans about incorporating integrated approaches in production landscapes Reviewed

    A global crisis for production landscapes has shed light on the importance of sustainable management of these landscapes in an integrated manner at local and national levels. However, there is a lack of quantitative research on the integration of relevant concepts into national-level policies and planning. Thus, we analyzed the National Biodiversity Strategy and Action Plans (NBSAPs) of 133 Convention on Biological Diversity parties using a text mining method to determine the current global situation regarding production landscape policies. The statistical results showed that (1) about half of parties mentioned integrated approaches in production landscapes (e.g., cultural landscapes, socio-ecological production landscapes and seascapes), (2) there were some regional differences in the number of references, (3) the introduction of these concepts has been increasing worldwide, and (4) these concepts have been accorded higher priority in national policy and planning.

    Scenario analysis with integrated quantitative modelling has become a common approach to investigate possible future socio-ecological systems in sustainability research. Facing several barriers on the use of scenarios, however, a participatory scenario approach has gained wider attention in place-based environmental research communities. In this paper, we investigate future ecosystem services (i.e., food production, carbon sequestration, nutrient retention, and habitat provision) in the explorative manner in the Sado island, Japan, using a participatory scenario approach and spatial ecological-economic modelling techniques. The contributions of this paper to the existing literatures are twofold: the one is collaborative use of morphological analysis and participants' votes for more fair and transparent scenario building, and the other is a suite of spatial modelling techniques, inter alia, land-use projections using a spatial multinomial logit model, for more robust and accurate simulations. Taking such innovative approaches and constructing the ecosystem service index reflecting local perceptions, we built distinctive six scenarios and projected future ecosystem services. As consequences, we could (1) illuminate the trade-offs between land-based ecosystem services, (2) highlight the importance of adequate mosaic structures in providing bundle of ecosystem services, and (3) visualize the spatially heterogenous impacts of alternative scenarios that imply one scenario does not fit all areas. We also discussed the interpretation of a sink service from sustainability perspectives and lessons learned from the parallel approach of participatory scenario building and quantitative modelling exercises.

  • Scenario analysis of land-use and ecosystem services of social-ecological landscapes: implications of alternative development pathways under declining population in the Noto Peninsula, Japan Reviewed

    Population-decline and subsequent underuse of social-ecological landscapes are increasingly being recognized as one of the crucial drivers behind the loss and deterioration of biodiversity and ecosystem services. In line with this, the study aimed to explore how alternative development pathways influence future land-use patterns, biodiversity and ecosystem services against a rapidly declining population in the Noto peninsula of Japan. By combining land-use simulation and evaluation of ecosystem services, the study formulated four exploratory scenarios for 2050, assuming a contrasting level of the society's reliance on domestic natural capital and different demographic patterns. At first, we analyzeds historical land-use changes between 1997 and 2007 and thereby simulated four plausible alternative scenarios using the Multi-Layer Perceptron Neural Network model. These scenarios were further used to quantify ecosystem services and landscape heterogeneity (as biodiversity indicator). The scenario analysis demonstrated that future land-use pattern could vary drastically depending on how the society utilize local natural capital even under the severe depopulation trend, whereas demographic patterns, in general, did not make discernible differences in land-use, biodiversity and ecosystem services. Nevertheless, a land-use change made considerable differences in the level of ecosystem services and landscape heterogeneity with varying degrees. Our analysis suggested that ecosystem services such as food production and nitrogen retention as well as landscape heterogeneity would decrease considerably by 2050 under the scenarios where the utilization of local natural capital decline and a significant amount of farmland are abandoned. Our findings highlight the vital role of land-use and agricultural policy in shaping the future availability of ecosystem services and biodiversity in this area.
