Urban growth containment policies for the guidance and control of peri-urbanization: a review and proposed framework

The purpose of this study is a review of urban growth containment policies for the guidance and control of peri-urbanization. The review of selected resources illustrates two policies: "urban growth containment policies based on planning interventions (UGCPI)" and "urban growth containment policies based on financial interventions (UGCFI)". The analysis of these policies reveals their distinct effects inside and outside the metropolitan boundaries, which, despite the positive results, create various practical consequences and challenges. This highlights the necessity of a special framework of growth guidance and control of peri-urbanization in response to the consequences and challenges of previous policies. The proposed framework is based on the four fundamental components, including regular growth, continuous activity interactions, optimal performance, and institutional capacity building that integration between them can make it possible to guide changes during the time. Certainly, the consequence of such an approach is the regular functional and structural landscape of peri-urban areas in the twenty-first century.

Determination of the optimal land use allocation pattern in Nowshahr County,Northern Iran

Regional models of land use change are evaluated as a way of identifying land use pattern based on recent quantitative and probabilistic approaches. Differentiation between models in this area is the result of the approach to the concept of land use and type of indicators used in the modeling process. Since the determination of the optima land use pattern, due to the different uses of land based on the availability of regional capabilities and spatial difference in land use, depends on an integrated model, there must be a model that can assess the existing conditions of the region and present reasonable models of land use according to regional capacities and potentials. In this research, we developed a model to present the Optimal Land Use Allocation Pattern (OLUAP) for maximizing the advantages of change and determining the methods of influencing land use change priorities. This model uses spatial models and analysis, moderates the cost-benefit function, and calculates the allocation priorities of various areas based on regional conditions. The model results show that a wide scope of Nowshahr area is allocated to natural and agricultural uses. At the same time, a limited area has been assigned to urban and industrial uses. In addition, it shows that northern strip of the region due to higher accessibility of services and infrastructures is more suited than other regions to urban and industrial areas, and these two uses have first and second priority, respectively. Besides, according to the man-made environment and the special environmental conditions, the model allocates the central lowlands and southern parts sporadically to agricultural and natural areas as first and second priorities. Since the model is spatial optimization, the suggestions of the model show the OLUAP. Therefore, one can see the optimal condition for each plot and compare it with the existing land use.
