In 2000, to efficiently implement land-use policies, the Taiwanese government amended the Agricultural Development Act by easing restrictions on agricultural land purchases. As a result of increasing land development and investment needs, agricultural land prices have surged. This study aims to examine whether agricultural land prices in Pingtung County are affected by land control policy measures, the pressure of agricultural land conversion and the degree of urbanization. A multilevel analysis approach was used to analyze land price differences in townships in Pingtung County.

Visual pollution (VP) in the form of outdoor advertisements (OA) is a threat to landscape physiognomy. Despite their proven usefulness in landscape aesthetic studies, landscape metrics have not yet been applied to address the phenomenon of VP. To fill this knowledge gap, a methodological framework for the measurement of VP using tangential view landscape metrics is proposed, which is accompanied by statistically significant proofs.

In recent decades, a new paradigm on the rational and careful use of land as a non-renewable resource has arisen. This definition requires new management methods based on the application of the “CLORPT” equation (state factor model) (CL—Climate, O—Organisms:living beings, R—Relief (topography), P—Parent material. T—Time. Thus, factors that we determine, as well as the impacts of planning, are analysed. We have used the factor model CLORPT (is an instrument by which any planning model can be analysed and diagnosed (e.g., planning carried out in the Ordesa National Park (Huesca-Spain)).
