Introduction to Grant Projects

Tanada Network

Surveying and creating a network of regional rice terrace conservation organizations

Activity grant

Project Description

In addition to producing rice, rice terraces also play a role in conserving water resources, biodiversity, and scenery. As environmental conditions worsen due to the abandonment of agricultural land, public interest in these terraces as human-managed natural landscapes is increasing. This project intends to survey 30 organizations that are involved in conserving rice terraces across Japan on topics such as corporate partnerships and conservation initiatives, announce the results of the survey at a symposium, and create a network of these organizations. A report will be compiled and published after three years.

Establishment purpose
If you imagine a river, rice terraces would be upstream and towns and cities downstream. If the upstream section is damaged, the downstream section suffers as well. Tanada Network finds various ways to connect rice terrace areas that need support with urban residents who want to support them, such as conducting farming experiences and support activities in these areas, as well as raising awareness of their diverse functions. It aims to contribute to the creation of a sustainable, recycling-based society by forming bonds of mutual understanding and cooperation between people in rural and urban areas.
