When the Ministry of the Environment was seeking the designation of the Amami Archipelago as a national park for the purpose of registration as the World Heritage site, it proposed two management concepts, “Ecosystem Management Type” and “Environmental Culture Type,” with the support of Kagoshima University, which had launched the Kagoshima Environmental Studies Project, a public-private collaboration aimed at solving environmental problems in the region. The “Ecosystem Management Type” concept aims to preserve the area as a registered World Natural Heritage site, while the “Environmental Culture Type” concept supports cultural value by providing visitors with a chance to experience the history and culture of people who have lived in harmony with nature in the area, and have skillfully used and passed it on to future generations. The purpose of Japan's national parks is to protect natural scenic areas, promote their use, and contribute to conservation of biodiversity. “Amamigunto National Park” was the first national park to propose the concept of an Eenvironmental Culture Type” national park that focuses on the nature and culture of the region. The term “Amamigunto” means “the Amami Archipelago”.

The Ministry of the Environment and Kagoshima University conducted an interview survey in collaboration with local residents in the satoyama area of Amami, a candidate area for a national park, to visualize the language and spirit that represent the culture of the islanders and how they live using nature. We also cooperated with local museums to understand the local environmental culture that has coexisted with nature. Through many workshops and symposiums, including web-based workshops, the results of the survey were shared with local residents and people from Amami living in the city, and through understanding the uniqueness and value of the local environmental culture, the awareness that environmental culture has the potential to strengthen community identity and seed independent economic development in the region. This awareness has spread.

Explanation of Amami NP's definition of “environmental culture”.
“The general consciousness, lifestyle, and production style that local people have formed and acquired while interacting with nature and influencing each other.”

Case Studies of Environmental Culture
Example 1) The topography of the “high island” and “low island” in the Amami Islands determines the amount of water in the rivers, which in turn determines how the islanders secure water for daily use and how they obtain firewood. On the “high islands,” waterwheel-powered sugar production using the abundant river water became more active, and trade flourished, strongly influencing the culture and consciousness of the islanders. This culture and consciousness has influenced the islanders' approach to nature and has defined the island's natural environment.

Example 2) The awareness of the forbidden by the yokai Kenmun in the island's folklore has become a means of appropriate control of natural resources and coexistence with nature.　The “yokai” is closely English word for “ghost” or “supernatural creature”.
 

In the context of fisheries and aquaculture, the fish trap represents an evolution of existing harvesting methods. Unlike active fishing gear, such as seines, the fish traps require less labor and energy, which makes them very efficient in terms of catch effort. In addition, the fish traps do not physically harm the caught fish, so the fish can be taken out of the trap alive and in good health. Early experiments on partial harvests in aquaculture in Malawi date back to the 1990s, when different tools for intermittent harvest were tested. However, due to the inefficiency and labor-intensity of the methods, there has been no broad application or further developments.

Based on this knowledge, further literature research, and expert discussions, the idea was born to build and test a size-selective fish trap to regularly harvest the juveniles of the initial fish stock. This innovation is thought to control the stocking density, to optimize the use of supplementary feeds, and to not exceed the carrying capacity of the pond. Ideally, a successful application of the fish trap would result in households increasing their overall aquaculture productivity, whilst harvesting small quantities of small fish much more regularly than has been customary in aquaculture to date. The intermittently harvested fish can be consumed within the household or used to generate small amounts of regular income. Meanwhile, the initial fish stock (parent fish) will be grown to a larger size for the final harvest.

In a fish-loving country like Malawi, where fish is the main source of animal protein, but fisheries yields are in decline, great hope and effort is placed in the development of aquaculture. Better access to and regular consumption of fish, which is an important source of protein and essential micronutrients, can make an important contribution to overcoming development challenges. And food insecurity is one of the greatest in terms of public health. Women and children are particularly affected by malnutrition. The expansion and promotion of sustainable aquaculture represents an important approach to meeting a growing demand for fish.

This development requires – among many other aspects – innovations that contribute to successfully mastering challenges in the sector. With a focus on rural aquaculture, the Aquaculture Value Chain for Higher Income and Food Security Project in Malawi (AVCP), part of the Global Programme ‘Sustainable Fisheries and Aquaculture’ under the special initiative ‘One World – No Hunger’ of the German Ministry for Economic Cooperation and Development, is providing technical training to 4,500 small-scale producers in Malawi. Fish farming helps them improve both income and food security.

One of the common and complex challenges in rural aquaculture is the use of mixed-sex Tilapia fingerlings in low-input systems. This means that farmers only have a limited selection and quantity of agricultural by-products available with which to feed a rapidly growing fish population in the pond. This leads to increasing competition for oxygen and food, which leads to poor growth rates and often an acceleration of sexual maturity. Accordingly, final harvests often consist of rather small fish, which does not meet the widespread expectations of harvesting edible – “plate filling” – fish from aquaculture.

Given the unavailability or prohibitiveness of mono-sex fingerlings, fish feed and aerators in rural aquaculture, the project was challenged to find an alternative solution to improve the productivity of rural aquaculture and its contribution to household nutrition.

Using the Google Earth Engine (GEE) platform, Landsat TM/OLI series remote sensing data from 1990 to 2022 were collected, covering TM5, ETM+7, OLI8, and OLI9. Key spectral bands (near-infrared, red, and green light) were fused to ensure high-quality data for subsequent analysis.

After needs have been identified and the approach has been agreed upon, the site selection process begins. The APW team collaborates with the village government and grazing committee to conduct a participatory mapping exercise, using Google Earth Pro to visualize the village’s land use plan and identify grazing areas. Community members help identify key pasture areas by walking transects. Monitoring plots are then identified, typically recommending one plot per square kilometer of critical pasture.

A plot ID–utilizing a local name–is designated for each plot and baseline data is collected using a mobile data collection form. The data includes both ecological metrics (e.g., grass height, soil type) and social factors (e.g., cultural significance, accessibility). 

GIS technology is utilized to overlay selected plots onto the village’s land use plan using Google Earth Pro, ensuring the final sites reflect the ecological diversity and grazing importance of the rangelands.

This collaboration has been crucial for knowledge exchange and the adaptation of advanced metabarcoding techniques to Lebanon. The Smithsonian team provided best practices on implementing DNA-based methods in ecological studies and offered expert advice on selecting the most suitable tools and instruments for metabarcoding analysis. This partnership has strengthened the scientific foundation of our project and ensured that our approach aligns with international standards.

The building blocks of NoArk's solution are interconnected to create a comprehensive, efficient system for conservation and environmental management. Bio-acoustic and chemical sensors collect critical ecological data, while Edge AI processing ensures rapid, on-site analysis, enabling immediate detection and response. These components are supported by LoRaWAN connectivity, which facilitates reliable, long-range communication in remote areas.
