Abstract

Corridors are important for preserving landscapes, ecosystems, biological diversity, and historical-social values.

An integrative model for the delineating and evaluating of green landscape corridors was developed that implements the principles of dynamic delineation and multivariable evaluation. The integrative model was designed to overcome the intrinsic land-use conflict by considering a wide range of both promoting and inhibiting factors. These factors are examined over time and space using an integrative model. The delineation of corridors includes constructing a database and accurately defining the delineation of core areas and corridors using geo-statistical methods. . The evaluation model developed, based on the Analytical Hierarchy Process (AHP) method, is used here to formalize expert knowledge. This method was used to determine the evaluation factors and their weights in order to assess and compare green landscape corridor alternatives.

The work describes the main stages in developing the integrative model's evaluation and delineation methods and the feasibility of implementing the model in Israel's northern region.

Using dynamic delineation, six green landscape corridor alternatives were identified that connect Mt. Meron Nature Reserve, Mt. Carmel National Park, and the Gilbo'a Mountains. In parallel, eleven evaluation factors were selected and structured hierarchically under four categories: area size, nature-development interface, natural characteristics and statutory characteristics. The relative weights and priorities of the various evaluation factors were determined according to the AHP method.

A statistical clustering tool (Agglomerative Hierarchical Clustering, AHC) that identifies clusters of similar results was also used to identify different evaluation strategies: the pragmatists group and the idealists group.  The evaluation factors and their weights resulted in an evaluation of corridor alternatives obtained in the dynamic delineation process according to these two strategies.

The delineation of alternatives and their evaluation led to the following conclusions: (1) Dynamic delineation enables the development of a set of green landscape corridor alternatives, considering promoting and inhibiting factors; and (2) integrating the evaluation model enables the identification of evaluation factors and the determination of their weights and interrelations, to allocate green landscape corridor alternatives regionally.

Implementing the method in Israel's northern region validated its feasibility and also alluded to its applicability in other areas and to the possibility of establishing it as a practical tool regarding land-use allocation decision-making.
