    Fit-for-purpose inspired approaches to land tenure recordation are being developed and implemented mainly in the form of pilot projects in various countries and application contexts. These approaches combine mobile digital technologies and flexible database structures with community based approaches for capturing and managing tenure rights. We discuss 10 such initiatives. A basic commonality of the initiatives is the general approach to tenure recordation through community based digital data capture, in many cases via mobile applications ā€“ where formal land registration does not suffice or has failed and acknowledging the diversity of land tenure regimes. Looking at the initiatives in more detail a number of differences become apparent in terms of financing mechanisms and organizational characteristics, as well as process design and application domains. Our discussion provides a basis to point out directions for future research as well as points of consideration for evaluation of implementation efforts and the aim of achieving citizensā€™ tenure securit

    EcoGIS ā€“ GIS tools for ecosystem approaches to fisheries management

    Get PDF
    Executive Summary: The EcoGIS project was launched in September 2004 to investigate how Geographic Information Systems (GIS), marine data, and custom analysis tools can better enable fisheries scientists and managers to adopt Ecosystem Approaches to Fisheries Management (EAFM). EcoGIS is a collaborative effort between NOAAā€™s National Ocean Service (NOS) and National Marine Fisheries Service (NMFS), and four regional Fishery Management Councils. The project has focused on four priority areas: Fishing Catch and Effort Analysis, Area Characterization, Bycatch Analysis, and Habitat Interactions. Of these four functional areas, the project team first focused on developing a working prototype for catch and effort analysis: the Fishery Mapper Tool. This ArcGIS extension creates time-and-area summarized maps of fishing catch and effort from logbook, observer, or fishery-independent survey data sets. Source data may come from Oracle, Microsoft Access, or other file formats. Feedback from beta-testers of the Fishery Mapper was used to debug the prototype, enhance performance, and add features. This report describes the four priority functional areas, the development of the Fishery Mapper tool, and several themes that emerged through the parallel evolution of the EcoGIS project, the concept and implementation of the broader field of Ecosystem Approaches to Management (EAM), data management practices, and other EAM toolsets. In addition, a set of six succinct recommendations are proposed on page 29. One major conclusion from this work is that there is no single ā€œsuper-toolā€ to enable Ecosystem Approaches to Management; as such, tools should be developed for specific purposes with attention given to interoperability and automation. Future work should be coordinated with other GIS development projects in order to provide ā€œvalue addedā€ and minimize duplication of efforts. In addition to custom tools, the development of cross-cutting Regional Ecosystem Spatial Databases will enable access to quality data to support the analyses required by EAM. GIS tools will be useful in developing Integrated Ecosystem Assessments (IEAs) and providing pre- and post-processing capabilities for spatially-explicit ecosystem models. Continued funding will enable the EcoGIS project to develop GIS tools that are immediately applicable to todayā€™s needs. These tools will enable simplified and efficient data query, the ability to visualize data over time, and ways to synthesize multidimensional data from diverse sources. These capabilities will provide new information for analyzing issues from an ecosystem perspective, which will ultimately result in better understanding of fisheries and better support for decision-making.

    From Data to Actions in Intelligent Transportation Systems: A Prescription of Functional Requirements for Model Actionability

    Advances in Data Science permeate every field of Transportation Science and Engineering, resulting in developments in the transportation sector that are data-driven. Nowadays, Intelligent Transportation Systems (ITS) could be arguably approached as a ā€œstoryā€ intensively producing and consuming large amounts of data. A diversity of sensing devices densely spread over the infrastructure, vehicles or the travelersā€™ personal devices act as sources of data flows that are eventually fed into software running on automatic devices, actuators or control systems producing, in turn, complex information flows among users, traffic managers, data analysts, traffic modeling scientists, etc. These information flows provide enormous opportunities to improve model development and decision-making. This work aims to describe how data, coming from diverse ITS sources, can be used to learn and adapt data-driven models for efficiently operating ITS assets, systems and processes; in other words, for data-based models to fully become actionable. Grounded in this described data modeling pipeline for ITS, we define the characteristics, engineering requisites and challenges intrinsic to its three compounding stages, namely, data fusion, adaptive learning and model evaluation. We deliberately generalize model learning to be adaptive, since, in the core of our paper is the firm conviction that most learners will have to adapt to the ever-changing phenomenon scenario underlying the majority of ITS applications. Finally, we provide a prospect of current research lines within Data Science that can bring notable advances to data-based ITS modeling, which will eventually bridge the gap towards the practicality and actionability of such models.This work was supported in part by the Basque Government for its funding support through the EMAITEK program (3KIA, ref.

    Designing a novel virtual collaborative environment to support collaboration in design review meetings

    Get PDF
    Project review meetings are part of the project management process and are organised to assess progress and resolve any design conflicts to avoid delays in construction. One of the key challenges during a project review meeting is to bring the stakeholders together and use this time effectively to address design issues as quickly as possible. At present, current technology solutions based on BIM or CAD are information-centric and do not allow project teams to collectively explore the design from a range of perspectives and brainstorm ideas when design conflicts are encountered. This paper presents a system architecture that can be used to support multi-functional team collaboration more effectively during such design review meetings. The proposed architecture illustrates how information-centric BIM or CAD systems can be made human- and team-centric to enhance team communication and problem solving. An implementation of the proposed system architecture has been tested for its utility, likability and usefulness during design review meetings. The evaluation results suggest that the collaboration platform has the potential to enhance collaboration among multi-functional teams

    Repair Matters

    Get PDF
    Repair has visibly come to the fore in recent academic and policy debates, to the point that ā€˜repair studiesā€™ is now emerging as a novel focus of research. Through the lens of repair, scholars with diverse backgrounds are coming together to rethink our relationships with the human-made matters, tools and objects that are the material mesh in which organisational life takes place as a political question. This special issue is interested to map the ways that repair can contribute to organisational models alternative to those centered around growth. In order to explore the politics of repair in the context of organization studies, the papers gathered here investigate issues such as: repair as a specific kind of care and socially reproductive labour; repair as a direct intervention into the cornerstones of capitalist economy, such as exchange versus use value, division of work and property relations; repair of infrastructures and their relation with the broader environment; and finally repair as the reflective practice of fixing the organizational systems and institutional habits in which we dwell. What emerges from the diversity of experiences surveyed in this issue is that repair manifests itself as both a regime of practice and counter-conduct that demand an active and persistent engagement of practitioners with the systemic contradictions and power struggles shaping our material world

    City Data Plan: the conceptualisation of a policy instrument for data governance in smart cities

    This paper presents the conceptualisation of the City Data Plan, a data governance policy instrument intended to connect the production and use of urban data in a comprehensive and evolutive long-term strategy aligned with city development goals. The concept of the City Data Plan had been elaborated by taking into account current issues related to privacy and manipulation of data in smart city. The methodological approach adopted to define the nature of a City Data Plan is grounded on the conceptual and empirical parallelism with corporate data governance plans and general urban plans, respectively aimed to regulate decision-making powers and actions on data in enterprise contexts, and the interests of local stakeholders in the access and use of urban resources. The result of this analytic process is the formulation of the outline of a City Data Plan as a data governance policy instrument to support the iterative negotiation between the instances of data producers and data users for instantiating shared smart city visions. The conceptualisation of the City Data Plan includes a description of the multi-stakeholder organisational structures for the city data governance, cooperation protocols and decision areas, responsibilities assignments, components of the plan and its implementation mechanisms
