Shaping up the Future Spatial Plans for Urban Areas in Pakistan

: Since 2007, more than ﬁfty percent of our planet’s population is living in urban areas. In the coming decade, the rate of urbanization will be fastest in Asia and Africa. Within South Asian countries, urbanization has attained its fastest pace in Pakistan. Urban planners and agencies in Pakistan have tried various spatial plan making solutions to manage urban areas, but none have given the desired results. After a 20% increase in declared urban areas within last two decades, urban planners and policy makers are looking for a more innovative and realistic spatial planning solution, which could adjust to the uncertainties and complexities of real world. This research uses a mixed method approach comprising a two phased survey of professional planners, analyzed through the selective lexicon approach to document planners’ opinions about the reasons behind the poor performance and conformance of spatial plans. This study documents the planners’ understanding of the contemporary concept of ‘scenario planning’. To explore the solution, this paper presents a semi-systematic review of the literature on the application of the ‘scenario method in urban spatial planning’. As a result of this research, a comprehensive digital inventory of all spatial plans ever made in Pakistan has been developed. It has been found that 83% of the urban settlements in Pakistan are growing without a spatial plan and require immediate attention. Furthermore, in terms of the plan making process, twenty-seven major factors contributing to the failure of past plans have been identiﬁed and categorized under seven distinct plan making stages. Finally, a new process of spatial plan-making has been proposed, which is the fusion of scenario planning and the traditional plan-making process, backed by digital planning tools. In an era of smart cities and digitization, it is expected that the advancements in scenarios planning, coupled with a new data portal, will assist in addressing the implementation gap in practice, and result in more comprehensive data-driven spatial plans.


Introduction
In our already urbanized planet, the major chunk of future urbanization will be concentrated in Asia and Africa [1,2]. Countries employ different policy instruments to manage spatial growth in Due to such definitional challenges and data abnormalities, none of Pakistan's cities were selected to be part of the global urban atlas [31]. The absence of standardized national level gazetteers for urban areas poses a new challenge in the temporal mapping of urban areas, making it land-use to explore the actual trend of urban centers increase in various regions.
Like many other developing countries, Pakistan faces the issue of data deficiency in urban statistics. Unfortunately, even the Bureau of Statistics does not provide a publicly available list of declared urban areas. Regarding the mapping of urban areas, two efforts are particularly important to highlight. The first one is the Global Human Settlements Urban Centre Database (GHS-UCDB), which has identified 301 settlements as 'Urban' from all over Pakistan. Despite its excellent global methodology, this does not cover the full picture of Pakistan. Another effort is at a sub-national level, which has appeared in the form of the Punjab Cities Growth Atlas, covering 194 cities of Punjab (the most populous province of Pakistan), and presents their expansion till 2015 [32]. However, both studies are not sufficient to cover the full spectrum of urban areas inventory in Pakistan. This reflects the need for the mapping of the declared urban settlements over time, and making it available in the geospatial format.

Evolution of Scenario Planning in Global Context
As the uncertainty increased in the real world and forecasts started going wrong, the concept of 'scenario planning' has started gaining the attention of the urban planners. The term 'scenario', after being introduced by Kahn in 1960s as "hypothetical sequences of events constructed for the purpose of focusing attention on causal processes and decision-points", was defined from various angles by other scholars [33]. In its very essence, a scenario is a structured representation of a probable future that narrates how the future might unfold if a series of events take place along a time scale. From the land-use planning perspective, a scenario represents the landuse pattern of a given space that would appear if a certain set of plans, policies and regulations are implemented during a period of time [34].
In the last sixty years, a lot has been written on 'scenarios', their components, building techniques and scenario planning approaches. In the current body of knowledge, work on terminologies, theory and concepts has been done by Schoemaker, Godet, Myers, Hopkins, Susan, Honton and others [35][36][37][38][39][40][41]. Another group has explored the applications of the scenario method in various fields, including urban planning [10,34,42,43], transport planning [44][45][46][47]. Similarly, research has been done in exploring the ways on how scenario planning can be welcomed and integrated in the planning process [34,35,43,[48][49][50]. Furthermore, another group has documented the scenario planning applications in real life or lab-based projects [50][51][52]. In addition to that, a group has been working on the development and documentation of digital planning tools and planning support systems to ease such scenario planning integration in urban planning.
Building upon the work of Clark [34], Table 1 exclusively enlists studies and project reports that demonstrate the application of the scenario planning approach in urban planning projects.  (Doxiadis, 1966;1967;1970;Schneider, 1972) 3 1975 A study of energy consumption, land-use, and growth policy for metropolitan Washington, DC USA (Roberts, 1975) [72] In the discussion of scenario planning for urban and regional planners, the prominent work is being done by the Lincoln Institute of Land Policy, which has been taking steps to document guidelines for the adoption of scenarios in urban studies [8,9,72,73].
Parallel to the evolution of scenarios, there has been extensive progress on the design and adaptation of digital planning tools [51,[74][75][76][77][78]. By digital planning tools, we refer to all kinds of ICT and GIS based decision support systems and planning support systems (PSS), which have been developed to aid urban planners in planning tasks. There is a wider acceptance and belief that the field of digital planning tools, especially PSS, has evolved as an effective contributor to support the planning process, and it greatly enhances the quality of planning outputs [75,[79][80][81][82][83][84][85][86][87]].

A Review of Spatial Planning Practices in Pakistan
As described in the previous section, academia and professional planners in USA, Australia and Europe are emphasizing and adopting the scenario planning approach either as a mainstream planning process, or as a sub-component of the larger urban planning process. However, the urban planners in Pakistan are still struggling with approaches that are almost outdated in their countries of origins.
In the last seventy years, many spatial planning solutions and plan types have been adopted in various cities. Qadeer believed that spatial plan making initially started as an effort to beautify the city, which then advanced to a process of development management [88]. Anjum has distributed the history of spatial planning in Pakistan in four eras. Stage 1: 1947-1960 when the focus was more on functional efficiency and public health, the segregation of land uses and the provision of infrastructure. Stage 2: 1960-1980 when the focus was on long-ranged, detailed land use plans, developed after extensive field surveys. This era was strongly influenced by the British 1947 Act, which resulted in the use of Master Plans, Landuse Plans and Zoning Plans. Stage 3: 1980-2000 focused upon long-ranged development plans prepared under national and regional policies, and the regulation of private sector land development. This was influenced by the British development plan system of the 1970s. Resultantly, we could see the Structure Plans and Local Plans being developed for many cities in Pakistan, along with the continued development of master plans and Outline Development Plans. Finally, stage 4: 2001-2008, which reflects urban planning after the Devolution Plan of 2001. This era focused on new century agendas and focused on private sector development, community involvement, environmental sustainability and demonstrative projects. However, in terms of plan shape, this era could not establish a definite answer to apply these concepts [15]. In 2009, Landuse Rules 2009 was introduced, resulting in the preparation of Peri-urban plans and Landuse Classification/Reclassification plans. This reflected a shift of focus from already developed built-up area to peri-urban areas, which were urbanizing at an alarming rate, resulting in major land use shifts. Voices were raised to limit urban boundaries and use geospatial technologies in the plan making process [16,89]. Consultants led planning remained dominating in the past decade. However, spatial planning could not become a top priority of the government; resultantly, the majority of the plans prepared after 2009 could never get approval. In 2019, the change of political government in Pakistan brought spatial planning to the limelight again. The government has initiated an ambitious 'Nya (new) Pakistan Housing Programme', which targets to deliver five million houses to public. Furthermore, they have emphasized the preparation of 'master plans' for all major urban centers.
So far, a few researchers in Pakistan have commented on the quality and efficacy of various spatial plans. Anjum, Ahmad and Hussnain have reviewed the spatial planning approaches and their products. Anjum and others have documented the stages in plan preparation process and have listed the major reasons behind the failure of plans in Pakistan [15,20,21,90,91]. Hameed et al. have commented on the master planning approach, and the challenges of implementing urban master plans [17]. Aziz et al. have focused on the implementation aspects of the master plan, and their discussion explains the institutional dynamics and legislative loopholes [92]. Adeel has assessed the challenges in the implementation of Rawalpindi Guided Development Plan, using remote sensing and GIS [93]. Hameed et al. have commented on the master plan for greater Lahore 1966, Lahore Urban Development and Traffic Study 1980 and Integrated Master Plan for Lahore 2021. They have observed and summed up the major deficiencies which led to the plans' failure. While documenting the reasons behind the failure of master plans, they raised questions about the nature and style of the development plan, which could respond to the cultural and institutional context and socio-economic and political realities of the country [17,89]. Khurshid has been advocating to think beyond conventional styled master plans [94,95].

Materials and Methods
This research is exploratory in nature, which is geographically focused on Pakistan in terms of problem exploration, but looks at the global literature and international best practices for seeking solution. It uses mixed methods approach to achieve its objectives. To ascertain the urban spatial plans availability gap, it starts with the development of digital inventories (declared urban areas vs areas having spatial plans). After that, it uses the literature review to enlist factors that have contributed to the failure of various urban spatial plans in Pakistan. A two phased expert opinion survey from professional planners (n = 55) has been conducted to validate those factors and document the factor weights. A semi-systematic literature review has been conducted for scenario planning and its application in urban planning. Based on the web search, a list of urban planning projects has been compiled where scenario planning process has been used. The lessons from the scenario planning projects have been fused to the existing spatial planning process of Pakistan and a new step by step guide has been proposed to make future spatial plans in Pakistan.

1.
Extraction of declared urban areas from the census data Every national census (1951,1961,1972,1981,1998 and 2017) has declared a set of settlements as 'urban', based on varied definitions. The census data has been published by Pakistan Bureau of Statistics in the form of PDF documents without digitally sortable tables. PDF to MS Excel conversion with optical character recognition (OCR) techniques, along with a Python based rows sorting mechanism, have been applied to extract data, which was then manually sorted to pick urban settlements. Finally, a matrix has been generated to document the increase in the number of declared urban settlements over the census periods among various provinces. The urban settlements have been mapped using the geocoding process to visualize the temporal increase in urban areas. To geocode the place names, a combination of Google Fusion Tables and place names from Open Street Maps (www.openstreetmap.org) and City Population (http://citypopulation.de/) have been used (See Figure 1).

Prepare an inventory of all spatial plans in Pakistan From the review of online resources and departmental libraries, a list of spatial plans has been developed, along with key meta data attributes, including spatial plan type, preparing agency, year of preparation, plan duration, approval status and status of plan validity. It is important to highlight that most of the previous plans have been collected in a printed or scanned format, which are not computer text readable. Hence, we have done a manual meta data listing for the preparation of an inventory, instead of a content based lexical analysis. Entries for the inventory have been searched and populated from multiple sources, listed in Table 2. An effort has been made to collect the means of verifications for each entry in terms of the plan document and/or plan map.

3.
Literature Review: The literature review has been conducted for two key purposes. First, to understand what has been documented about the causes behind the failure of various urban spatial plans. This review is geographically focused on Pakistan. Second, a semi-systematic review of the published literature has been conducted on a global scale, using EBSCO, Google Scholar, Web of Science and Scopus, to explore the application of scenarios in urban planning. Key terms used for searching include "scenario planning", "scenario and urban planning", "scenario planning applications", "scenario method in land use planning", "scenario in urban planning projects". A lot has been written on the scenario method in general, so attention was paid to exploring the application side in the urban planning domain. Furthermore, an effort was made to enlist urban planning projects where scenario planning has been adopted as a process. Lessons from the projects have been used to improvise the spatial plan-making process for Pakistan.

4.
Experts opinion survey: A two-phased survey of urban planning experts have been conducted in 2019, to record their opinion about the factors behind the failure of urban spatial plans and experts' aspiration for a futuristic plan-making process. A total of 55 urban and regional planners were contacted, out of which 46 responded. The survey recruitment criteria included "qualified urban and regional planners", "more than 10 years of experience" and "involvement in a previous urban spatial plan-making process". An effort was made to get respondents from academia, government, industry and non-government sectors, along with representation from all provinces.
In the first phase, experts were asked to share their opinion about "how well the spatial plans were able to achieve their objectives in Pakistan?" on a Likert scale of 1 to 10, where 1 equates not at all, complete failure; 5 = neutral and 10 = to a great extent. They were asked to qualitatively describe the causes behind the failure of spatial plans in narrative form. The qualitative data, so collected, were analyzed using the Selective Lexicon Approach-Level-3 [96]. Resultantly, the key words were generated, and a list of 26 factor statements were developed against seven major stages of traditional plan making process. The seven stages were also derived from the literature review, and the first round of experts' opinion. In the second phase, the list of twenty-six factor-statements was presented to the experts, to express their opinion about the contribution of each factor towards the failure of urban spatial plans on a 5-point Likert scale. Furthermore, experts were asked to select which type of urban spatial plans (master plan, outline development plan, peri-urban structure plan, regional plans, structure plan) have performed better in the context of Pakistan and why. In addition, experts were asked to respond some open-ended questions, to document their suggestions on potential improvements in the spatial plan-making process, the viability of data-driven planning and readiness for adopting future-oriented planning approaches.

Finally, the research synthesizes the lessons and findings of all the above-mentioned processes, and concludes by offering a way forward. its application in urban planning. Based on the web search, a list of urban planning projects has been compiled where scenario planning process has been used. The lessons from the scenario planning projects have been fused to the existing spatial planning process of Pakistan and a new step by step guide has been proposed to make future spatial plans in Pakistan.

Documentation of Declared Urban Areas vs. Spatial Plans' Availability
The compilation of the urban areas and its spatial mapping reveals Punjab to be the densest province, containing 257 declared urban areas, as per the census of 2017, followed by Sindh, which has 197 urban areas. The third place is attained by Khyber Pukhtunkhwa (KPK) province, which has 62 urban areas. Baluchistan, the largest province in terms of the area, is fifth place, with 61 urban centers. After that, Azad Jammu & Keshmir (AJK) has 25, Federally Administered Tribal Area (FATA) has 16, while Gilgit Baltistan has five declared urban areas (See Table 3). To have a deeper look at the phenomena, the urban settlements have been mapped down based on their geographic coordinates (see Figure 2, where one dot represents one urban settlement). It is clear that the increase in number and size of cities in Punjab and Sindh provinces is along the water bodies and agriculturally rich areas, which are considered the food basket for Pakistan. 62 urban areas. Baluchistan, the largest province in terms of the area, is fifth place, with 61 urban centers. After that, Azad Jammu & Keshmir (AJK) has 25, Federally Administered Tribal Area (FATA) has 16, while Gilgit Baltistan has five declared urban areas (See Table 3).
As compared to the previous census of 1998, the highest increase in the number of declared urban areas appear in Sindh province, which has 37 new urban places, followed by AJK, having 19 new places, Baluchistan and Punjab both have 15 new localities, FATA has 11, while KPK has eight new settlements declared as urban.
To have a deeper look at the phenomena, the urban settlements have been mapped down based on their geographic coordinates (see Figure 2, where one dot represents one urban settlement). It is clear that the increase in number and size of cities in Punjab and Sindh provinces is along the water bodies and agriculturally rich areas, which are considered the food basket for Pakistan.  In summary, there has been a substantial increase in the declared urban areas and their sizes. As per the latest census, urban planners and city managers have to focus on 624 urban settlements to prepare their spatial plans, out of which, a significant proportion (36%) are inhabited by more than 50,000 people.
After the quantification of urban settlements at the national level, this research has enlisted and mapped the availability of spatial plans. The analysis reveals that out of 624 declared urban areas, only 179 could ever had a spatial plan, leaving more than 70% of the cities to grow without a spatial plan (see Figure 4). Table 4 presents the detailed statistics on the availability of spatial plans, their validity and approval status. If we consider all the plans which have been made for urban areas (duplication considered), it can be noted that 229 spatial plans of various forms have been prepared in different periods, out of which only 162 could get formal approvals. Considering the plan periods, only 102 plans (both approved and unapproved) were still valid in 2019, while 111 expired. Spatial mapping of the urban areas that do or do not have an urban plan reflects interesting patterns. Keeping the validity aside, in Punjab, 54% (n = 140) of urban areas have some form of spatial plan, 35% (n = 9) in AJK, 12% (n = 23) in Sindh, 3% (n = 2) in KPK and in Baluchistan. Furthermore, plotting the spatial plans by type also yields interesting patterns (see Figure 3). The practice of preparing outline development plans and peri-urban structure plans has been more influential in Punjab, while Sindh has mostly adopted the master plans. Furthermore, the master plans have been prepared for the large cities, as compared to the smaller towns.

Factors Contributing to the Failure of Spatial Plans
To examine the factors contributing to the failure of spatial plan, a two phased expert opinion survey has been conducted. The frequency distributions of valid responses (n = 46) reveals that 24% of the experts belong to academia, 38% form government, 31% from industry and 7% belonged to non-government organizations. In terms of provincial distribution of responses, 64% experts have This analysis reveals that majority of the urban settlements (83%) in Pakistan are growing without a valid plan, and there is a dire need to focus on the preparation of spatial plans to control the harmful aspects of urbanization. There are a wide variety of spatial plans which have been tested by the development authorities, offering a broader spectrum to evaluate and learn from previous practices.

The frequency distributions of valid responses (n = 46) reveals that 24% of the experts belong to academia, 38% form government, 31% from industry and 7% belonged to non-government organizations. In terms of provincial distribution of responses, 64% experts have been from Punjab, 9% from Khyber Pakhtunkhwa and Islamabad Capital Territory each, 7% from overseas Pakistani planners and 2% from Baluchistan and Gilgit Baltistan each.
In line with the findings of the literature, the majority of the urban planners (62%) believed that urban spatial plans have not been able to achieve their objectives in Pakistan. A total of 13% gave a neutral response, while 24% responded on the positive side of the Likert scale, reflecting their opinion that plans have been able to achieve their objective to some extent.
When it comes to the identification of factors which have contributed to the failure of spatial plans and their average factorial ranking, factors related to the 'collaborated action' have been ranked as the most significant contributors, with an average score of 9.21, followed by factors linked to the stage of the 'implementation framework', having an average score of 8.92. Furthermore, the factors related to the 'goal formulation' has been scored at 7.6, followed by factors under 'stakeholder & community participation' with 7.18, and 'planning proposals formulation' with 6.75, 'detailed planning' with 6.56 and 'baseline studies' related factors with a 6.34 average score (see Figure 4a) Sustainability 2020, 12, x FOR PEER REVIEW 12 of 21 When it comes to the identification of factors which have contributed to the failure of spatial plans and their average factorial ranking, factors related to the 'collaborated action' have been ranked as the most significant contributors, with an average score of 9.21, followed by factors linked to the stage of the 'implementation framework', having an average score of 8.92.

These stages require corrective intervention in terms of theoretical input and execution tools. On the other hand, the strongest position has been attached by the stage-2 'baseline studies', with a score of 3.66, followed by the stage-5 'detailed planning', which has attained 3.44. Similarly, stage-3 'planning proposals formulations' and stage-4 'stakeholders/community participation' have scores of 3.25 and 2.82 respectively (See Table 5 and Figure 4b).

After a deeper dive within the stages, Table 6 presents the stage wise listing and ranking of 27 factors contributing to the failure of urban spatial plans. At the stage of goal formulation, this included the 'clarity of the implementation agency about the plan type and contents', with an importance score of 7.35 and 'inability of the agency in prioritizing relevant important themes and ensuring mechanism to assign due priority to the selected themes', with a score of 7.85. At the stage of baseline studies, three factors have been identified, which include 'absence/wrong collection of relevant data' (6.58), 'insufficient data collection' (6.22) and 'inadequate usage of digital planning tools (IT, GIS, PSS and RS)' (6.22). At the stage of planning proposals formulation, nine of the identified factors included 'inability of plan proposals to match with future vision and the absence of mechanism to establish link of proposal with future vision' (7.45), 'absence or inadequacy of alternate proposals' (7.35), 'inability of plan making process to consider all relevant planning variables' (7.04), 'inaccuracy of future estimates and projections' (6.89), 'insufficient data analysis' (6.68), 'insufficient alternate proposals' (6.58), 'high time investment on data collection as compared to synthesize in proposal making' (6.43), 'unexpected changes in the real world' (6.22) and 'weak contents and lack of comprehensiveness (thematic & geographic coverage)' (6.07). Similarly, under the stage of stakeholders/community participation, four factors have been listed, which include 'lack of community participation' (7.76), 'lack of stakeholders' engagement' (7.70), 'inability to effectively ensure incorporation of stakeholders' opinions' (7.50) and 'more focused on donor driven agenda rather than local agency's needs' (5.77).  Furthermore, at the stage of detailed planning, three factors have been identified, including 'insufficient skills of the plan making teams or absence of town planning professionals in the team' (6.73), 'faulty plan making approach' (6.58) and 'faulty plan preparation process' (6.38). At the stage of the implementation framework, four listed factors include: 'insufficient capacity of plan implementation agency' (8.78), 'absence of legal backing for plan implementation' (8.32), 'delayed plan approval' (8.16) and 'absence of financial model to execute planning proposals' (7.91). Last but not least, the stage of urban governance/collaborated action contains two factors, including 'weak enforcement mechanism' (9.29) and 'lack of ownership by implementing agency' (9.13) (see Figure 5). of the implementation framework, four listed factors include: 'insufficient capacity of plan implementation agency' (8.78), 'absence of legal backing for plan implementation' (8.32), 'delayed plan approval' (8.16) and 'absence of financial model to execute planning proposals' (7.91). Last but not least, the stage of urban governance/collaborated action contains two factors, including 'weak enforcement mechanism' (9.29) and 'lack of ownership by implementing agency' (9.13) (see Figure  5).

Scenario Planning; a Promising Solution to Uncertainty and Complexity
From the review of the literature on the applications of the 'scenario' method in urban planning, it is clear that scenario planning is particularly useful for decision making in the face of an uncertain future. Since it is not a separate planning process, it should be better used to build flexibility in the existing planning process.
Based on the real-life applications, scholars have extensively documented the benefits of scenario planning in generating dialogue among the stakeholders, unfolding conflicting agendas and helping the urban planning players understand the impacts of stakeholders' actions on other linked cycles. The scenario method is particularly useful in: (a) setting goals and imagining future preferred shape of the urban area, (b) the development of alternate proposals, (c) the meaningful engagement of stakeholders, (d) chalking out the implementation of frameworks and (e) identifying workable means for collaborative action.

Future Shape of the Spatial Plans
In the previous section, Figure 5b has indicated the areas which should be addressed to improve the situation. Considering the successful application of 'scenarios' and 'digital planning tools, especially planning support systems' in the spatial plan making process, we recommend that the lessons of these two knowledge streams must be incorporated in the traditional planning process of Pakistan to improve the process.
Since the factors behind spatial plans' failure have been organized against plan making stages, let us examine how the proposed approach and tools can fix and improve each stage. Figure 6 gives a graphical illustration of the type of intervention required at every plan making stage.
At the stage of goal formulation, scenario planning can greatly help stakeholders in clarifying stakeholders' vision. It allows all the stakeholders to focus on what is important for an urban area and how they want to grow to reach that goal [9].
During baseline studies, scenario based digital planning tools can help focusing on the collection of relevant data [51]. Adopting ICT based solutions and digital planning tools can ensure the sufficiency and efficacy of data. Furthermore, the use of digital planning tools (RS/GIS/PSS) can ensure time and cost efficiency [21,91,97]. Sustainability 2020, 12, x FOR PEER REVIEW 15 of 21 During baseline studies, scenario based digital planning tools can help focusing on the collection of relevant data [51]. Adopting ICT based solutions and digital planning tools can ensure the sufficiency and efficacy of data. Furthermore, the use of digital planning tools (RS/GIS/PSS) can ensure time and cost efficiency [21,91,97].
At the stage of planning proposals formulation, scenario method can help clarify the 'actors' and their potential roles in the shaping the future of cities. As an approach, building scenarios helps stakeholders to ensure that all relevant planning variables are being duly considered in the proposal formulation. The alternate scenarios help in formulating and assessing the proposals and their potential impacts. The traditional planning process lack the means to ascertain the future result of choices that can be easily handled by scenario planning. Scenario planning gives confidence to planners and decision makers that the logical input-out chain is well established, and that the chosen option will or will not lead to the desired goals. Furthermore, the use of scenario planning tools can ensure that future estimations are reasonably accurate and are in line with the ground realities. Planning support system allow the stakeholders to try out various scenario combinations and see the changes in real time [98].
A prominent benefit of adopting scenario planning and planning support systems is their ability to engage community and stakeholders in the planning process. Scenarios unfold hidden agendas and make the process transparent. They let community and stakeholders think outside the box and come up with innovative solutions to the problem at hand. Similarly, the ability to demonstrate the resulted changes on screens and dashboards make PSS extremely powerful in creating communal engagements, and ignite thinking process in focus groups.
In traditional planning, planning proposals are prepared in isolation, and the integrated impact of various proposals is hard to ascertain. Digital planning tools use a full spectrum approach, where it is not possible to hide any assumptions. They require planners to work out proposal in a detailed level. For instance, Envision Tomorrow PSS require plan makers to specify land uses for every parcel of the land and specify variables for each land use to generate an overall picture of the city. Similarly, Online WhatIf? PSS require the suitability factors to be very specific and comprehensive in order to generate future development scenarios. Resultantly, plan making teams work in a systematic and detailed manner, rather than overly simplifying the proposals.

Conclusions and Future Work
The continued pressure of urbanization has resulted in a rapid increase of declared urban areas in Pakistan from 468 to 624 from 1998 to 2017, respectively. In addition to the definitional issues within census report, these urban areas were not previously mapped to ascertain their geographical spread. Based on the synthesis of hard copy census reports from 1951 to 2017, this research produces At the stage of planning proposals formulation, scenario method can help clarify the 'actors' and their potential roles in the shaping the future of cities. As an approach, building scenarios helps stakeholders to ensure that all relevant planning variables are being duly considered in the proposal formulation. The alternate scenarios help in formulating and assessing the proposals and their potential impacts. The traditional planning process lack the means to ascertain the future result of choices that can be easily handled by scenario planning. Scenario planning gives confidence to planners and decision makers that the logical input-out chain is well established, and that the chosen option will or will not lead to the desired goals. Furthermore, the use of scenario planning tools can ensure that future estimations are reasonably accurate and are in line with the ground realities. Planning support system allow the stakeholders to try out various scenario combinations and see the changes in real time [98].
A prominent benefit of adopting scenario planning and planning support systems is their ability to engage community and stakeholders in the planning process. Scenarios unfold hidden agendas and make the process transparent. They let community and stakeholders think outside the box and come up with innovative solutions to the problem at hand. Similarly, the ability to demonstrate the resulted changes on screens and dashboards make PSS extremely powerful in creating communal engagements, and ignite thinking process in focus groups.
In traditional planning, planning proposals are prepared in isolation, and the integrated impact of various proposals is hard to ascertain. Digital planning tools use a full spectrum approach, where it is not possible to hide any assumptions. They require planners to work out proposal in a detailed level. For instance, Envision Tomorrow PSS require plan makers to specify land uses for every parcel of the land and specify variables for each land use to generate an overall picture of the city. Similarly, Online WhatIf? PSS require the suitability factors to be very specific and comprehensive in order to generate future development scenarios. Resultantly, plan making teams work in a systematic and detailed manner, rather than overly simplifying the proposals.

Conclusions and Future Work
The continued pressure of urbanization has resulted in a rapid increase of declared urban areas in Pakistan from 468 to 624 from 1998 to 2017, respectively. In addition to the definitional issues within census report, these urban areas were not previously mapped to ascertain their geographical spread. Based on the synthesis of hard copy census reports from 1951 to 2017, this research produces a unique dataset that is purely focused on urban areas. Issues related to naming conventions have been resolved; resultantly, it is possible to track changes in an urban area from 1951 to 2017. After linking the geographic coordinates to each declared settlement, it offers the very first geospatial dataset on declared urban centers in Pakistan. To create a wider impact, the dataset has been shared in open domain through PakistanGIS (www.PaksitanGIS.org; a Pakistan based forum to share open sourced geospatial datasets). Furthermore, based on the data of this research an online portal (accessible at www.PakistanUrbanPortal.org) has been established, which offers free access to the data and documentation on urban areas in Pakistan. Opening access to the data inventories presented in this research will resolve a key research barrier in the country, and can be used further to develop urban dashboards and visual platforms to support greater transparency and participation in the planning process, as discussed by Lock [99].
On the response side of rapid urbanization, development control agencies in Pakistan have been slow in preparing spatial plans, and a wide variety of spatial plan types have been prepared and executed. This research creates a national level digital inventory of spatial plans, which have been prepared across Pakistan. Comparing this inventory with the declared urban areas list has given us the spatial plans' availability gap. Results have been mapped as point data across Pakistan to see the spatial pattern across provinces. The widest gap exists in the Baluchistan and KP provinces, where only 3% of the urban areas have got their plans. In Sindh, 88% of the urban areas do not have a plan, in AJK it is 65%, while in Punjab, 46% of the urban areas do not have a future spatial plan. This presents an alarming picture for the development controlling agencies. However, the realization of these facts has been initiated. On many of the events organized on the World Town Planning Day (WTPD) 2019, planning professionals have raised a voice to declare an 'urban planning emergency' in the country, where all the left out urban areas should be prioritized for a future growth spatial plan.
Since there is an uprising of interest in the formulation of master plans for all cities in Pakistan, this research examines the factors behind the failure of past plans. A survey of 55 professional planners, engaged in past spatial plan making projects has been conducted to enlist and rank more than twenty-five factors contributing to the failure of plans on various stages of plan making. Ideas have been collected about the solutions to improve the conditions that have been triangulated from the world best practices of spatial plan making.
The review of the literature and the synthesis of the applications of scenario method in urban planning projects across the advanced world reflects the fact that 'scenario planning' (as approach) and associated 'digital planning tools and planning support systems' (as tools) are leading and promising solutions, which can counter most of the failure causing factors.
This research presents how the integration of 'scenario planning' and 'digital planning tools' in the spatial plan-making process can offer a solution to the plan making challenges. Considering the ground realities of Pakistan, a new process of spatial plan-making has been proposed, which is the fusion of scenario planning and the traditional plan-making process, backed by digital planning tools. However, the execution of this approach will not be an easy task. The capacity of planners in adapting the scenario approach, as well as applying planning support systems, can be a major stumbling block. Like the initiatives in other countries, there is a need to incorporate scenario planning in the core curriculum of urban planning schools in Pakistan and other developing countries, and to educate urban planning professionals on the approach. This aligns with recommendations by Russo et al. [100] in studying the use of planning support systems in Italy, Switzerland and Australia. Further research is needed to outline detailed procedural steps for incorporating the scenario method in spatial planning process [101].
