A prolegomenon

Anadromous salmonids are increasingly threatened by overfishing, overdependence on hatcheries, and loss of spawning grounds. This paper examines the Kushiro Wetland, a Ramsar site and Japan's largest protected wetland, as a potential area for promoting natural reproduction of anadromous salmonids. We argue that initiatives to protect natural reproduction of anadromous salmonids and wetland conservation efforts as mutually beneficial and necessary. Salmon is a keystone species that serves as a foundation for both the natural food web and the global fishery industry, and therefore a crucial factor in shaping the future health of the wetland ecosystem and the security of local people' livelihoods. First, this paper explores the benefits of naturally reproducing salmon for both nature and society from the perspective of the wetland ecosystem, drawing from examples of wetland conservation specific to natural reproduction of salmon. Second, by employing the framework of social-ecological system analysis, this paper provides an overview of the local environmental history of the Kushiro River Basin by examining how social-ecological interactions from the Meiji period to date has shaped the local ecology, with a focus on wetland and salmon. Over the years, the development of logging, dairy farming, and salmon propagation in the basin disconnected the mutually beneficial relationship between wetland and salmon by establishing and moving salmon capture sites to further downstream along the Kushiro River and into the heart of the wetland. Based on this analysis, this paper argues that natural reproduction of salmon in the Kushiro Wetland has the potential to reconnect lost ecological links and benefit the river basin ecology and the local community.

A perspective towards a

circular fashion design system

2019 | Book Chapter

The current fashion design, production, and consumption system, known as ‘fast fashion’, is characterized by the manufacturing of low-quality garments in a short period of time carried out in developing countries. In parallel with the deficits in social responsibility and human rights, the prevailing ‘take-make-dispose’ system in the fashion industry is one of the main causes of environmental pollution that concerns the climate change, scarcity of natural resources and health problems for the living beings. Due to these facts, discussions on Circular Design strategies – for waste reduction, components recycling, and materials reuse – became increasingly relevant throughout the globe. This paper’s aspiration is to outline a perspective towards a Circular Fashion. The concept of the Design for Sustainability requires a holistic view throughout de-signing strategies as well as the establishment of cyclical systems for the production site. Notwithstanding, the efficient integration of social and cultural dimensions are vital for Sustainable Fashion’s triumph.
