Building Sustainable Society Based on Regional Circular and Ecological Sphere

Abstract

I am researching the Aso region to clarify the multilayered area of the regional circular and ecological sphere and the method for its construction. The largest area is the basin of six class A rivers flowing down from the Aso region as a regional circular and ecological sphere. Approximately two million people live in this basin, and 2.3 million people in the Fukuoka metropolitan area also use its water resource. The population of the Aso area, which is the source of the water, is about 210,000, and it is estimated that the population will be reduced by half by 2050. In the Aso area, there are more than 20,000 hectares of semi-natural grasslands, which play a significant role as a groundwater recharge area. The area of the grasslands is decreasing year by year due to the aging of the people involved in maintaining and managing them, and it is predicted that more than half of the grasslands will be lost by 2050 compared to 2003. To halt the decline in grassland areas, it is necessary to reduce the amount of labor required for burning at the end of winter.
