THE ONE-HOUR CITY
Network analysis reveals the fine-grain fabric of the desakota. This one-hour city loop illustrates that the system continues to sustain a high level of local accessibility.

How: clusters and networks
Java’s predicament—between global//local, growth//preservation, top-down vision//grassroots action—reﬂects a related and equally profound schism: between urban theory and planning practice. In turn, this manifests at a technical level: space is mapped either by vectors or pixels. The former are perfect for accurately delineating policy boundaries, while the latter are ideal for geospatial analysis. The blindspots this methodological division creates, permeate the discipline. Researchers observe land use patterns one function at a time, while planning tasks break down along bureaucratic silos and discreet design projects. Integration fails from the start. This is most notable in emerging markets where muddled peri-urban landscapes hamper standard spatial research, and sophisticated administrative structures often lack along which strategic visions can cascade down to decentralised, project-based interventions.
In response MJ45 applies two advanced GIS-based technologies: land use cluster analysis and time-based network analysis. These technologies allow new cross-scalar methods of spatial analysis.
Branded ‘R-G-B Cluster’ method, this gravitational analysis tool allows us to map urban, non-urban and non-buildable land use patterns in one model. Within regions of dispersed land use, larger patterns can be discerned to reveal networks structured around shared issues, such as water, rather than by political borders, thus opening the planning process up to community centred alliances. Network analysis reveals the potential of Central Java’s tollway. By including time, distance and graph density, we can generate a set of “accessibility scenarios”, such as the “one hour city”. With these models the impact and opportunities from new connectivity can be weighed, and national goals mediated by local realities.
Metro Java 2045 believes that tangible outcomes can be rooted in data models alone. Java’s often piecemeal urbanization is forged at the grassroots level by a range of socioeconomic drivers. Long-term growth strategies must provide agency to local stakeholders.
Studies have concluded that peri-urban developments tend to succeed only when they are issue speciﬁc, rather than generic, and organised in multi-disciplinary collaborations (Allen 2003). In a context where the municipal workforce is too small to sustain proper enforcement of zoning laws, urban development is mostly “aﬀordance driven”, in other words, shaped by what is possible, rather than by what is legal. The aﬀordances of a region are a set of drivers that range from land development, to job, educational and economic opportunities. In such a context, planning must be guided by the combination of enabling and disabling mechanisms. Instead of a large, rigid masterplans, drafted from afar, the peri-urban landscape tends to be best planned through strategically selected sites of intervention.
With the aid of R-G-B cluster maps, MJ45 sets out to identify the precise desakota subtypes for ten sites in Central Java. Data will be obtained through google earth imagery, desktop studies on zoning maps, interviews and site surveys—scoping irrigational systems, agricultural output, formal and informal services and industries, local densities, FARs and building typologies, and micro demographic and mobility trends.
The aim of these studies is to ﬁnd drivers for change that can generate speculative development scenarios. This feed into a catalogue of congruent sites that are shared online. Their commonalities allow for a ecology of solutions to be crafted that are applicable to a range of diverse desakota subtypes. At the heart is the goal to tap into economic incentives fostered by the community as the only viable alternative to the short investment cycles favoured by global urbanism. This is the mission of the Yogyakarta Heritage Society, who will take charge in guiding MJ45s extensive ﬁeld work.
The online platform plays a critical part in providing agency at the grassroots level. Beyond sharing critical land use information it provides an increased transparency throughout the process by connecting communities to initiatives. Secondly, as management is handed over to YHS, the platform will be provide a lasting database that can aid in future workshops and ongoing feedback generated in the comments section.
