Strategic spatial analysis of urban greenbelt plans in Mashhad city, Iran

Abstract

Background: Greenbelt, known as the most restrictive form of urban containment policy, is a geographical boundary around a city or urban region to prevent urban sprawl. In the present study, the urban greenbelt plans were investigated with spatial, temporal, and statistical attitudes in Mashhad city, Iran. Spatial and temporal data analyses were carried out in ENVI, and GIS programs based on satellite imageries in addition to the expert analyzes of SWOT (strengths, weaknesses, opportunities, and threats) and QSPM (quantitative strategic planning matrix) matrixes to achieve the key strategies concerning the revitalization of a new greenbelt plan. Results: Four temporal sequences of Landsat imageries were extracted for 1988, 1998, 2008, and 2018 to classify the expansion of real estates and urban sprawl. The results showed that the legal greenbelt plan failed after 10 years because the status of greenbelt in 2018 revealed nearly of occupation by sprawl expansion over than 20%. Then a new greenbelt plan was proposed around the city. Based on the lowest value of the environmental change index (ΔY i), with an average of 0.14, the proposed greenbelt plan will demonstrate an optimum efficiency in the future time intervals (2030-2050). Conclusions: Therefore, expert analyzes of SWOT and QSPM matrixes were shown that the essential weakness of greenbelt planning in the Mashhad city depends on the lack of a legal mechanism to conserve the greenbelt boundaries. Therefore, the total sum score of external factor's matrix with the value of 2.65 demonstrated that the opportunities for greenbelt planning in the study area are more effective than threats in the study area. Ultimately, six key strategies in greenbelt planning were presented to achieve a general equilibrium through future urban development.

“…The green belts in many countries can be seen as one of the most internationally recognized attempts to control urban growth (Kardani-Yazd et al, 2019). Green belts have encircled large cities to keep them from expanding (Amati 2016).…”

“…In many countries, the introduction of the green belt can be considered one of the best-known international policies that manage urban growth (Han, 2019). The green belt has ringed larger cities to keep them from spreading (Kardani-Yazd & Daneshvar, 2019). Planners are trying to steer urban growth towards sustainable land use.…”

Beberapa permasalahan seperti masih adanya hambatan sistem dan prosedur pengelolaan rusunawa, minimnya respon dari MBR untuk menempati bangunan rusunawa dan belum optimalnya kerjasama lintas sektoral merupakan permasalahan yang harus dihadapi oleh Dinas Beberapa penelitian tentang kebijakan perumahan menyebutkan bahwa kelemahan mendasar perencanaan perumahan terutama untuk pemenuhan ketersediaan rusunawa bagi MBR yaitu tidak adanya regulasi hukum dan tidak adanya peluang untuk mencapai strategi keseimbangan pembangunan perumahan perkotaan (Kardani-Yazd et al, 2019). Selain itu, strategi prioritas yang dapat mendorong faktor peluang untuk menutupi permasalahan kelemahan rusunawa seperti operasi dan pemeliharaan, sedimentasi, kerusakan dan ancaman seperti pencurian air, perusakan bangunan, banjir serta memaksimalkan kekuatan (kondisi komponen, fungsi, aksesibilitas masih belum optimal (Sumiarsih et al, 2018), sehingga (Moazeni, 2016) dalam hasil penelitiannya menunjukkan bahwa strategi kebijakan prioritas adalah mengembangkan perencanaan yang komprehensif, strategis dan jangka panjang untuk pembangunan perkotaan berkelanjutan dalam sistem manajemen perkotaan.…”
