The formation of approaches with the attitude of advocacy planning can be related to the existence and continuity of spatial and socioeconomic inequality and the conventional failures of planning. In Iran, planners who work as urban planning engineers in most of the consulting engineer’s companies, or in person, can use their expertise to encourage citizens to follow their legal rights and to increase their social participation. Examples can be found in plans that are intended to change the land use through the Organization of the Engineering System to eligible city planners. The purpose of the present study is to review the literature of advocacy planning and its application to urban land use adaptation plans. It also tries to show the relations between land use adaptation plans and advocacy planning theory in terms of topics, methods, and goals (the relation between theory and practice). The methodology of the present research is qualitative and data were collected through deep interviewing techniques and nonreactive measures (archival records). The field theory approach has been adopted to analyze the information and to present the final theory. Based on the qualitative sampling method of the typical case study and the theoretical saturation criterion, the views of thirty-five experts in the field of urbanization have been used in this study and their perception of the research questions have been analyzed. Using the "grounded theory" method and data coding, nine core categories were extracted from the initial findings. The result of the present study, with regard to the final core category, indicates that “urban adaptation schemes cover many aspects of advocacy theory in urban planning, and can be considered as a practical dimension in many aspects of Advocacy Planning Theory”. The findings reveal the deep relationship between the theory of planning advocacy and urban land use adaptation plans.

Land Surface Thermal (LST) is a key variable to control the relations between different types of radial, latent, and sensible thermal fluxes in urban areas. For analyzing and understanding dynamics of LST, it is necessary to recognize its relations with changes created by men. Recognizing such relations is a requirement for modeling and predicting environmental changes and also for urban policies. On the other hand, increases occur in vegetation cover is an effective strategy to reduce the effects of urban microclimate. The present study analyzes the trends of surface thermal changes and its spatial correlations with vegetation cover in Tehran metropolitan during 2003 to 2016. Free clouds satellite images of Tehran by Landsat8 (August 2016) and Aster (August 2003) were analyzed using Envi software. Different algorithms of remote sensing were applied to convert LST and Normalized Difference Vegetation Index (NDVI) indicators into spatial patterns. Spatial outcomes of the present study indicate that during a decade the minimum amount of surface thermal and the average amount of LST have decreased 3.67°c and 0.47°c respectively. In contrast, the average amount of NDVI was increased from 0.06 to 0.10. Also, the estimation of spatial correlation between LST and NDVI indicators showed an amount 0.02 reduction in 22 urban regions of Tehran metropolitan during the last decade. Such a reduction indicates that increasing functions of human activities have affected the rates of thermal and energy of urban surfaces. Therefore, to reduce energy consumption in the city, it is evident that different patterns of physical development should be applied for the city.
