Abstract
In recent decades, urban population growth has led to an increased demand for food resources. In such a context, innovative approaches such as urban agriculture development have been proposed. The present study aims to investigate the trends in urban agricultural land changes within the boundaries of Marivan city from 1972 to 2022. It seeks to assess the available land, potentials, and strategies for the development of urban green spaces based on urban agriculture principles. The research methodology employed a descriptive-analytical approach, utilizing Landsat satellite imagery for data collection. Radiometric and atmospheric corrections were applied, along with the NDVI index using ENVI software. After generating maps, the evolution of land use changes and the extent of available land for urban agriculture in the study area were examined for the year 2022. Furthermore, this research provides practical solutions and recommendations for the implementation of urban agriculture in Marivan city, based on its potential. A noteworthy aspect of this research is its intention to explore the suitability of land and potentials for urban agriculture in Marivan as a new model for developing urban green spaces. The results of the study indicate that urban agricultural lands have gradually decreased over various periods from 1972 to 2022 due to the city's growth and other human activities in peri-urban areas. However, as of 2022, approximately 2,799 hectares of land are available for urban agriculture, serving as a new model for the development of green urban spaces in Marivan. Several factors contribute to Marivan's success in maintaining agricultural lands and orchards in peri-urban areas. These factors include its favorable climate and geography, strategic location, proactive policies, water resource management, commercialization of agricultural products, prevailing economic conditions, and a substantial labor force. The region has experienced relative climatic stability, ensuring the sustainability of its agricultural lands and orchards.
