Chiba Fieldwork Report — Coastal Work and Resident Participation
Associate Professor Seino Satoko of Kyushu University explained that it is known
sandbars form where sand collects at the bottom of surfing locations and that beaches
with plovers are known to have bait, noting the importance of attracting the interest of
local residents who observe the sea from day-to-day. The person responsible for Chiba
Prefecture said since there are links between monitoring and consensus building,
consideration of the effect on fisheries and the ecosystem made powerful common sense
with the current positioning of the Seashore Act.
Shima and Toba Fieldwork Report — Initiative between Toba City Asari (Short-Necked
Clam) Study Group and Shima City
Shima City Sato-umi Creation (里海創生) Basic Plan (Shima City Coastal General
Management Plan) FY2012 ~ 2015
Tidal marshes at three city localities are being regenerated to increase marshlands but
there are difficulties with reclassification of old land that has been classified as fallow
land to "agricultural land".
Discarded oyster shells in Toba City have been processed and natural seeding of asari
short-necked clams is under way. Stocking of spat from other areas is attracting
attention due to fear of invasive alien species.
２． Examples of Work in Each Field
Incentives Related to Biodiversity Loss in Upland Agriculture
Upland agricultural village maintenance (agricultural land improvement), such as land
reclamation, irrigation and drainage, farm road maintenance, agricultural land disaster
prevention, etc., is performed using subsidies from national, prefectural, and local
governments. It could be said that organisms living and growing in paddy fields today
are more or less influenced by the subsidy "business". Villages like Yatsuda in Chiba
City, Chiba Prefecture, are maintained through receipt of measures such as the Chiba
Prefectural Village Regulations, Grants for Upland Regions, Grants for Agricultural
Environmental Conservation, etc., as promotion measures.
Subsidies for Problem of Invasive Species
Assistance was examined from the viewpoint of preventing invasive species in the field
of environmental conservation by non-governmental organizations such as NPOs. There
were found to be few assistance systems in fields other than for countermeasures to
invasive species. Among these, the most common was for tree planting. Invasive
herbaceous plants and bivalves are being used as water purifiers. There have been
