Landscape Degradation Assessment (LDA) of rural areas can play a crucial role in landscape planning. Japan lacks quantitative and cumulative Environmental Impact Assessment (EIA) methodologies, especially in the area of LDA. Although a decision support system is in place for very large projects (Class-1) in Japan, EIAs for much smaller projects are non-existent, which often results in ambiguity with regard to environmental problems. To improve the transparency of the decision-making process for rural landscape planning, increase the scale of the assessment of project size to a more strategic local level, and enhance effective communication with decision-makers, a new EIA procedure is proposed with the development of a Landscape Degradation Model (LDM) for rural areas in Japan. The procedure is based on the equation, L[D]=Σ kI/V, where L[D] represents the degradation coefficient of the landscape compartments, Σ kI represents the cumulative impact of human activities, and V quantifies the vulnerability of a habitat. The value of L[D] provides a means for supporting decisions aimed at the quantitative prioritisation of working units and developing respective conservation plans. This methodology is a holistic approach to rural landscape reclamation decision support systems where these LDM findings are geared toward sustainability appraisal and where integrated assessment of the economics of a proposal is recommended.
