Summary Individual land titling will not deliver land tenure security to the majority of people by 2030. Nevertheless, tenure security is implicit to the 2030 Agenda for Sustainable Development and deep-rooted in the Sustainable Development Goals (SDGs). Land tenure security underpins the SDGs related to poverty reduction, food security, disaster risk management and gender equality. The cross-cutting benefits of land tenure security with regards to sustainable development suggests equally cross-cutting conceptual frameworks, management cooperation and data sharing are needed within, and between, those sectors. Additionally, previous research in the land administration domain developed approaches, frameworks and data models linking across different domains. This latter achievement showed how developments using standardised modelling approaches and domain terminologies can be used to support gathering, organising and disseminating information relevant to reporting on and monitoring of the SDGs. From the perspective of data sharing, domain models - such as the Land Administration Domain Model LADM (ISO 19152), a globally recognized standard - are seen as supporting this capability. In response, this paper explores whether and how LADM, in terms of data model additions and adaptations, could support other SDG-relevant domains. The approach used is exploratory, including elements of literature review, case study analysis, conceptual data modelling, and synthesis. It shows the potential and added value of an integrated data modelling approach, with regards to Land Administration and its intrinsic feature to other fields of study including poverty reduction, food security, and gender equality.

Land reallocation is an important step of land consolidation where farmland parcels are reorganised and redistributed. Most current land reallocation approaches focus on the technical aspects, at the expense of the social, cultural, economic, and political factors which are important on customary lands. This paper develops an approach for land reallocation to support responsible land consolidation on customary lands taking these factors into consideration. Using the process model approach, we identify the key characteristics of customary land tenure and the general requirements for land reallocation of these lands; from which a land re-allocation approach is developed. This is subsequently applied to a case study in Northern Ghana. The results show that even though the approach is successful to the extent that land fragmentation (physical and legal) is significantly reduced in the study area; social land mobility, land tenure and cultural practices hinder the application of the land reallocation as this would either increase legal or physical land fragmentation.

Unstructured data, non-relational databases, distributed databases, and big data analytics potentially change the landscape for digital land data creation, use, management, and dissemination. The way land data is governed and the resultant impact on land tenure security delivery is open to substantial re-thinking. Drawing from international cases, this paper provides a state-of-the-art examination of prototypes and demonstrators from the global land sector. The aim is to deliver an insight into the opportunities, challenges, impacts, and future scenarios regarding the application of the emerging technologies. The paper finds that whilst uptake of non-relational and distributed databases is occurring, it remains largely at the level of proof-of-concept, demonstrator or pilot. Scaled uptake is occurring slower than anticipated, and to a lesser degree than in other sectors. However, the broader and longer-term impacts on the land sector remain difficult to judge. Meanwhile, emerging distributed analytical databases appear to be under-exploited or at least underexplored within the land sector. Overall, the examined technologies are seen to enable new operational approaches for conventional land sector transactions, and also entirely new land related services, digital products, and actors: the ways and means of holding, transferring, and securing land may become more nuanced, fractionalized, and/or automated. Whether these observed embryonic developments lead to sector transformation or orderly transition, is seen to be heavily reliant on the prevailing political, socio-cultural and institutional settings within a jurisdiction.

The global land community has increasingly recognized the need to work towards practical, coordinated integration and scalable implementation of alternative approaches to land administration, ones that better serve the interests of the majority of groups in society. The pro-poor land recordation tool (PPLRT) contains a set of design elements developed to improve protection and access to land for the poor, particularly women, youth and vulnerable groups, especially in areas with (rapidly) changing land use. Building on earlier PPLRT work, this article positions the PPLRT relative to other responsible land administration approaches (especially Fit-For-Purpose). It further develops the PPLRT design elements and system based on incorporating increased foci on institutional and political economy aspects and a more complex notion of community, stemming from four documented cases of records keeping, and expert feedback. The paper recommends refinement of all but one of the design elements, addition of a new design element, and modification of the PPLRT’s graphical depiction. Recommended strategic areas for further research are: assessing the impacts of pro-poor land recordation on achievement of the SDGs (particularly land related indicator 1.4.2) and New Urban Agenda (particularly paragraph 35); identifying the necessary conditions for improved, coordinated, and scaled PPLRT implementation in various contexts; and articulation of the circumstances for effective future alignment, conversion and integration of land data collected by local communities with those of existing land administration agencies.

A contemporary review of land administration, from the perspective of systems maintenance, is provided. A special emphasis is placed on emerging fit-for-purpose land administration solutions. The research synthesis uses reputable sources from the contemporary era. Results show the challenges of maintaining land administration systems and the data held are long recognized. The 1970s–1980s gave the issue impetus as data and processes moved from paper-based and manual to digital and automated. The 1990s recognized concerns on maintenance, albeit as a secondary issue: system establishment was the primary concern. The 2000s placed more emphasis on more holistic sociotechnical systems but, again maintenance was supplementary. The fit-for-purpose era deliveres a vast range of new social and technological innovations; however, scaled and sustainable implementations still struggle with system maintenance. From the findings, a consolidated model for analyzing maintenance problems and solutions at jurisdictional level is developed. Maintenance of a land administration system can be understood by identifying the level of change, method for change, components to change, and options for what to change to. The United Nations-endorsed Framework for Effective Land Administration is then used to identify specific maintenance challenges and available solutions. It is suggested that due to the scope and size of what can be considered maintenance issues, there exists no single solution—instead the country should identify its persistant maintenance problems, and the most appropriate solution set from the suite of available options. Emerging solutions and challenges include ensuring interlinkage to maintenance of spatial planning, land valuation, and marine administration; exploiting survey data ‘back capture’ initiatives; supporting grassroots IT; and giving serious attention to cybersecurity concerns.

Contemporary global policy development is increasingly shaped through the Sustainable Development Goals (SDGs). In parallel, the United Nations initiative on Global Geospatial Information Management (UN-GGIM) plays a leading role in the development and diffusion of policy frameworks with regard to geospatial information. Specifically, two frameworks, the Framework for Effective Land Administration (FELA) and the Strategic Framework for Geoinformation Services for Disaster (SFGISD), are under development to tackle global issues in relation to tenure security and natural disasters. In order to harmoniously diffuse those global goals and frameworks into national laws and regulations, and to local community initiatives and policies, policy transfer is required to occur between governance layers. This paper seeks to assess ‘whether’ and ‘how’ this policy transfer occurs, focusing specifically on identifying limitations and its opportunities for its enhancement. Results reveal that the approach so far used for policy transfer is taking conventional institutional means to do this in both domains land administration and disaster risk management (DRM) domains. There appears to be an opportunity to utilize a networked approach instead of the conventional institutional for a more robust and further-reaching uptake of the policies. This could also give space to provide better mechanisms for feeding results from local level initiatives and successes into the global frameworks.

Disaster prevention, response and recovery require information about land tenure. Though, in many high-risk contexts, such records are non-existent or not up to date. As a result, vulnerable groups are often passed over by the government during risk management activities. At present there exists no dedicated tool for supporting land tenure recordation of all people-to-land relationships for the purposes of disaster risk management. More specifically, the required supportive data models and standards that could enable integration of concepts from the respective domains of land administration and disaster risk management are also lacking. Standardized data models could support software and service designs. This paper introduces a model linking the domains of land administration and disaster risk management – with the goal of supporting resilience against natural disasters and providing an approach for collecting data once, and using it multiple times. A design approach was used to develop the model – with adaption of the international Land Administration Domain Model (LADM) standard acting as a basis. Key features of the model include the support of interoperability through standardisation, the inclusion of all people-to-land relationships including those specific to disaster contexts, and the potential of the model to contribute to each of the disaster phases. The model is suggested to be highly applicable in natural disaster contexts where no land tenure information exists or the national mapping authority already uses a land administration system compatible with LADM. Overall, the model is considered as a step toward an implementable strategy for applying responsible land administration in the context of disaster risk management.

Conventionally, land administration—incorporating cadastres and land registration—uses ground-based survey methods. This approach can be traced over millennia. The application of photogrammetry and remote sensing is understood to be far more contemporary, only commencing deeper into the 20th century. This paper seeks to counter this view, contending that these methods are far from recent additions to land administration: successful application dates back much earlier, often complementing ground-based methods. Using now more accessible historical works, made available through archive digitisation, this paper presents an enriched and more complete synthesis of the developments of photogrammetric methods and remote sensing applied to the domain of land administration. Developments from early phototopography and aerial surveys, through to analytical photogrammetric methods, the emergence of satellite remote sensing, digital cameras, and latterly lidar surveys, UAVs, and feature extraction are covered. The synthesis illustrates how debates over the benefits of the technique are hardly new. Neither are well-meaning, although oft-flawed, comparative analyses on criteria relating to time, cost, coverage, and quality. Apart from providing this more holistic view and a timely reminder of previous work, this paper brings contemporary practical value in further demonstrating to land administration practitioners that remote sensing for data capture, and subsequent map production, are an entirely legitimate, if not essential, part of the domain. Contemporary arguments that the tools and approaches do not bring adequate accuracy for land administration purposes are easily countered by the weight of evidence. Indeed, these arguments may be considered to undermine the pragmatism inherent to the surveying discipline, traditionally an essential characteristic of the profession. That said, it is left to land administration practitioners to determine the relevance of these methods for any specific country context.

Public-private partnerships (PPPs) may facilitate the implementation of fit-for-purpose land administration (FFPLA), however, the approach can be compromised when funding for land registration is insufficient or donor projects end. This paper aims to introduce a new form of PPP to the literature on FFPLA, further extending the discourse and options available on PPPs for FFPLA. A background review finds that whilst PPPs have had long standing application in land administration, there is room to explore approaches that seek increased involvement of non-conventional land sector actors. A case study methodology is applied to analyse recent developments of FFPLA in Côte d’Ivoire that includes a partnership between the government and a consortium of private sector companies. Results describe the novelty, challenges, opportunities, and success factors for the approach, when compared to existing forms of PPPs. It is found that the innovative partnership approach may create novel avenues for financing FFPLA in developing countries and for more active forms of participation of the private sector in improved land tenure governance. The model potentially creates sustainable buy-in from private sector corporations, who whilst not conventionally closely undertaking land administration efforts, rely intrinsically on it to achieve corporate social responsibility objectives.

Land consolidation is argued as a tool for increasing food security. However, past attempts to consolidate Sub-Saharan Africa's rural customary lands disregarded the existing land tenure system, and actually undermined food security: land fragmentation, which supported the traditional farming system, was not considered a problem, and more importantly, the projects merely attempted to transfer Western European land consolidation without taking local conditions into account. In response, this study aims to identify the factors that need to be understood when developing a land consolidation strategy for the specific case of Ghana's rural customary lands. The determining factors when selecting a land consolidation strategy are identified for three countries with existing land consolidation strategies: The Netherlands, Lithuania, and Rwanda. Subsequently, these are set against Ghana, which has no land consolidation strategy, but has customary lands. It is found that certain determining factors in Ghana - such as the state of the economy, and the farming technology - matched with the strategies of other countries. However, other factors including: the government support; the prior existence of conventional land markets; an individual land tenure system; and the coverage of a functioning land information system – were all absent in Ghana. The study concludes that the factors that differ require ways to be addressed and adapted in order to develop a responsible land consolidation strategy for Ghana's customary areas.

The objective to fast-track the mapping and registration of large numbers of unrecorded land rights globally has led to the experimental application of Artificial Intelligence in the domain of land administration, and specifically the application of automated visual cognition techniques for cadastral mapping tasks. In this research, we applied and compared the ability of rule-based systems within Object-Based Image Analysis (OBIA), as opposed to human analysis, to extract visible cadastral boundaries from very high-resolution World View-2 images, in both rural and urban settings. From our experiments, machine-based techniques were able to automatically delineate a good proportion of rural parcels with explicit polygons where the correctness of the automatically extracted boundaries was 47.4% against 74.24% for humans and the completeness of 45% for the machine compared to 70.4% for humans. On the contrary, in the urban area, automatic results were counterintuitive: even though urban plots and buildings are clearly marked with visible features such as fences, roads and tacitly perceptible to eyes, automation resulted in geometrically and topologically poorly structured data. Thus, these could neither be geometrically compared with human digitisation, nor actual cadastral data from the field. The results of this study provide an updated snapshot with regards to the performance of contemporary machine-driven feature extraction techniques compared to conventional manual digitising. In our methodology, using an iterative approach of segmentation and classification, we demonstrated how to overcome the weaknesses of having undesirable segments due to intra-parcel and inter-parcel variability, when using segmentation approaches for cadastral feature delineation. We also demonstrated how we can easily implement a geometric comparison framework within the Esri&rsquo, s ArcGIS software environment and firmly believe the developed methodology can be reproduced.

Unmanned Aerial Systems (UAS) are emerging as a tool for alternative land tenure data acquisition. Even though UAS appear to represent a promising technology, it remains unclear to what extent they match the needs of communities and governments in the land sector. This paper responds to this question by undertaking a socio-technical study in Rwanda, aiming to determine the match between stakeholders’ needs and the characteristics of the UAS data acquisition workflow and its final products as valuable spatial data for land administration and spatial planning. A needs assessment enabled the expression of a range of land information needs across multiple levels and stakeholder sectors. Next to the social study, three different UAS were flown to test not only the quality of data but the possibilities of the use of this technology within the current institutional environment. A priority list of needs for cadastral and non-cadastral information as well as insights into operational challenges and data quality measures of UAS-based data products are presented. It can be concluded that UAS can have a significant contribution to match most of the prioritized needs in Rwanda. However, the results also reveal that structural and capacity conditions currently undermine this potential.

Land consolidation activities have generally failed in the Sub-Saharan African region for various reasons. However, there has been a new wave of land consolidation activities in the past two decades. This study examines how contemporary land consolidation activities in Sub-Saharan Africa contribute to the achievement of the SDGs, specifically ending poverty, ending hunger, and developing sustainable cities and settlements through land tenure security, food security, and rural development initiatives at country level. Using cases from Rwanda, Ethiopia, and Ghana, the study draws lessons on how land consolidation activities can contribute to the 2030 agenda. In Rwanda, it is found that though land use consolidation is a locally developed strategy for food security, due to its focus on the national level, household food security is actually lowering. Perceptions of land tenure security are also lower, despite an increase in legal tenure security. In Ghana, it is seen that the technical processes of land consolidation, though they hold the potential to increase food security, they will not fit with the existing land tenure system. Finally, in Ethiopia, it is seen that a bottom-up land consolidation is flexible and sensitive to local needs, however, scaling is difficult without the strong governmental involvement. Overall, land consolidation in SSA could deliver significantly to those SDGs relating to food security, poverty reduction, and landscape management. However, realistically, to achieve measurable country-wide or regional impact by 2030, immediate and strong governmental support tied to collaboration with community leadership is essential.

There exists an intensifying and multifaceted relationship between rapid population growth, the increasing occurrence of natural disasters, and demands for land tenure security. Consequently, there is growing agreement on the need to adopt pro-poor land administration approaches, ones that better address the needs of the poor living in disaster prone contexts. Vulnerable communities and exposed lands could benefit from emerging pro-poor land administration, however, thus far, application of the pro-poor mind-set has gained minimal traction in the disaster risk management agenda. Using a research synthesis, existing evidence is analysed and consolidated, and a new inclusive conceptual framework is built; one that illustrates the underutilised potential for pro-poor land administration in disaster risk management. The developed framework explains the interactions between three identified and fundamental global change forces (people, land and disaster) and the three disaster risk drivers (vulnerability, exposure and hazard). The framework illustrates how pro-poor approaches can simultaneously have impacts on both land tenure security and disaster risk management. The conceptual framework is considered a first step toward an implementable strategy for applying pro-poor land administration technologies in the context of disaster risk management. Ultimately, pro-poor land administration should enable the poor to minimise vulnerabilities and disaster risks through an inclusive land tenure security approach to prevent, mitigate, prepare and respond to natural disasters.

Urbanization and the trend towards complex infrastructure development challenges the traditional two-dimensional (2D) cadastral representations used in conventional land administration. Three-dimensional (3D) representations are argued to serve as the future basis upon which to spatially define rights, restrictions and responsibilities (RRRs) in these environments. In Delhi, the capital city of India, where horizontal expansion via new settlements in peri-urban areas, and vertical expansion by densification of city infrastructure, are both prevalent, the need to manage this increasingly complex 3D infrastructure environment presents a great challenge for land administration and management agencies. This paper explores both the current and potential future application of 3D representation in Delhi, with respect to land use planning, development and management. A cross-cutting thematic case study analysis is undertaken: policy drivers, legal frameworks, organizational aspects, and technical standards are considered. For each aspect a separate analytical approach is used. Based on the results, it is concluded that current practices related to 3D representation are somewhat immature and not adequate for capturing the future vertical growth of Delhi. This could lead to legal and physical boundary inconsistencies and irregularities, and dispute cases. However, by learning from international developments and standards-based approaches, agencies have the potential to enhance and support processes in their respective land administration systems. To realize this potential, internal and external policies, institutional settings and, technical and financial arrangements need to be reformed. In the short term it is recommended to focus on raising awareness for the widespread adoption of 3D representations in relevant agencies in Delhi.

This paper presents the results from a quality and usability analysis of participatory land registration (PaLaR) in Indonesia’s rural areas, focusing on data quality, cost, and time. PaLaR was designed as a systematic community-centered land titling project collecting requisite spatial and legal data. PaLaR was piloted in two communities situated in Tanggamus and Grobogan districts in Indonesia. The research compared spatial data accuracy between two approaches, PaLaR and the normal systematic land registration approach (PTSL) with respect to point accuracy and polygon area. Supplementary observations and interviews were undertaken in order to evaluate the effectiveness of the spatial and legal data collection, as well as logical consistency of the data collected by the community committee, using a mobile application. Although the two pilots showed a lower spatial accuracy than the normal method (PTSL), PaLaR better suited local circumstances and still delivered complete spatial and legal data in a more effective means. The accuracy and efficiency of spatial data collection could be improved through the use of more accurate GNSS antennas and a seamless connection to the national land databases. The PaLaR method is dependent on, amongst other aspects, inclusive and flexible community awareness programs, as well as the committed participation of the community and local offices.

In this paper, we develop a framework for an approach that assigns values to customary rural farmland parcels based on the local people’s view of land value to support land consolidation. In a case study of Nanton, Ghana, key land value factors were identified and weighted by the local community. The weights were integrated into the framework that produced a Land Value Index for each farmland parcel. Though the strength of the approach is found in scenario and sensitivity analyses. However, the prime weakness of this framework is that it is more expensive to use than automatic valuation models.

Climate change challenges mountain communities to prepare themselves via Community-Based Adaptation (CBA) plans that reduce vulnerability. This paper outlines the evaluation of a developed web-based information system to support CBA, referred to as a Mountain Community Adaptive System (MCAS). The web-based user interface visualizes collated data from data providers, integrating it with near real-time climate and weather datasets. The interface provides more up-to-date information than was previously available on the environment, particularly on land and climate. MCAS, a cloud-based Land Information System (LIS), was developed using an Agile-inspired approach offering system creation based on bare minimum system requirements and iterative development. The system was tested against Fit-For-Purpose Land Administration (FFP LA) criteria to assess the effectiveness in a case from Nepal. The results illustrate that an MCAS-style system can provide useful information such as land use status, adaptation options, near real-time rainfall and temperature details, amongst others, to enable services that can enhance CBA activities. The information can facilitate improved CBA planning and implementation at the mountain community level. Despite the mentioned benefits of MCAS, ensuring system access was identified as a key limitation: smartphones and mobile technologies still remain prohibitively expensive for members of mountain communities, and underlying information communication technology (ICT) infrastructures remain under-developed in the assessed mountain communities. The results of the evaluation further suggest that the land-related aspects of climate change should be added to CBA initiatives. Similarly, existing LIS could have functionalities extended to include climate-related variables that impact on land use, tenure, and development.

Community-based Adaptation Programs (CAPs) that involve the participation of communities are being actively promoted in mountainous areas. These areas are climate sensitive and are often heavily influenced by landslides, floods, and drought. This research indicates that designers of adaptation programs seek to develop and implement CAPs based on international viewpoint and their obligations, but not community requirements. Such CAPs create uneven access to information resources for communities and do not implicitly reduce community vulnerability. In response, the research proposes the establishment of an Information System (IS) to support delivery of reliable climate adaptation services to mountain communities. This research uses Nepal as a case study that experiences a lack of effective adaptation programs due to its varied topography, prevalent climate-related disasters, and barriers in capacity building and institutional development. The results of the analyses indicate that the national level focuses on preparing adaptation action plans, whilst district levels and Non-Governmental Organization (NGO) focus on facilitating adaptation implementation for community and individuals. Additionally, the results reveal that an IS can enhance the design and implementation of CAP. Finally, the results are used to articulate prioritized services for an IS to assist communities who are in the greatest need of climate service delivery.

Land fragmentation has been identified to greatly undermine crop production in many countries. In the case of Ghana’s customary tenure system, household farmlands are relatively small and are highly fragmented. Recent agricultural drives, however, have focused on farm level interventions that are ad hoc with short-term benefits. A sustainable long-term application of land consolidation which reorganises farmlands may improve yields, reduce the cost of production and improve the incomes of farmers. The successful implementation of land consolidation depends greatly on the suitability of local conditions with respect to land tenure and land use. However, in Ghana’s customary lands, the alignment between the requirements for land consolidation and existing conditions remains unexplored. This study investigated the feasibility of land consolidation within the customary tenure by juxtaposing the local conditions of the study areas with the baseline conditions for land consolidation outlined in literature. Using both qualitative and spatial data, the study revealed some traits of convergence and divergence with respect to the baseline conditions in the study areas. For example, conditions such as the existence of land fragmentation, suitable topography and soil distribution were fully met. Conditions such as the existence of a land bank, technical expertise, and infrastructure and supportive legal frameworks were partially met. The remaining conditions such as the willingness to participate, availability of a land information system and favorable land ownership structure were non-existent. The circumstances surrounding these unmet conditions are deeply embedded in customs and traditions that hardly yield to change. Since these conditions are fundamental for land consolidation, their absence negates the feasibility of land consolidation under the current tenure system of the study areas.

In many countries, authority for maintaining records of land ownership lies with national or state institutes, called 'cadastres' or 'land registries'. The emergence of volunteered geographic information (VGI) and crowdsourcing potentially challenges this state based authority, enabling the construction of 'neo'-cadastres (using the analogy of 'neo'geography). Individual citizens can themselves map and record land tenure rights. This paper explores if and how VGI and crowdsourcing may redefine the state based cadastres and land registries, and the roles of land users who claim land rights outside of the state based institutions. Using theories of institutions and isomorphism we hypothesise that a parallel exists between emerging open systems and situations where no state-based cadastre exists: participants in both situations will position themselves to protect their interests. Three cases from Ghana, Canada, and Indonesia demonstrate how land users indicate their land tenure right boundaries based on personal views (the neo-cadastre), rather than on rules stipulated by a national authority (the traditional cadastre). In each case land users root their behaviour partly in local dependency relations and social advocacy networks. These locally embedded rules may not necessarily coincide with hierarchical institutional relations. Even in participatory adjudication activities conducted under the authority of national cadastres, land users are not completely free in providing their land boundaries. Instead, they adhere to certain locally embedded microsocial conventions. We conclude that VGI and crowdsourced based neo-cadastres will likely redefine, from passive to active, the roles of land users in cadastres. This creates an opportunity for citizens, but also a potential risk. Where implicit rules of the neo-cadastre do not co-evolve with traditional cadastral institutions, conflicts of land information and access to land may emerge. Neo-cadastres will be an artefact of this dissatisfaction, and may reflect new directions for cadastral institutions. Neo-cadastres will not be a direct trigger for wider cadastral change, but a piece of evidence that change and resistance are occurring

Urban land has social and spatial dimensions. Governance of urban land should consider these dimensions. Existing methods of evaluating land governance tend to focus on the social dimensions: the spatial dimensions are considered less. A socio-spatial approach developed here is argued to fill this gap. This research supposes that informal settlements can be used to understand urban land governance. A conceptual framework that links urban land governance, socio-spatial dimensions and informal settlements is developed and tested through a case study. The results show that the socio-spatial methodology improved understanding of equity, efficiency and transparency as compared with the existing approaches which are solely based on poor-quality and unreliable data. This methodology can be used beyond informal settlements such as understanding infrastructural delivery and quality, mapping potential conflict areas and urban land uses where governance plays a great role. Overall, the socio-spatial methodology enabled an all-encompassing evaluation of urban land governance

It is frequently argued that, at the parcel level, stakeholders are capable of and well supported in managing their land-related risks. Yet, evidence from the contemporary Australian context suggests otherwise: numerous large-scale disaster events have revealed that citizens are ill-prepared to respond and recover adequately. This paper begins with the premise that information, specifically land information, could better support parcel-level risk preparation, mitigation, response, and recovery. State land administration organisations in Australia primarily maintain this information and make it accessible. Land information is used regularly across all levels of government to support risk management activities; however, such application has not always occurred at the parcel and citizen level. Via a case study approach, this paper initially explores the land information available in Australia to stakeholders interested in parcel-level detail, and then goes on to propose how the utilisation of parcel-level land information could serve to enhance risk management practices.

Unmanned aerial vehicles (UAVs) provide a flexible and low-cost solution for the acquisition of high-resolution data. The potential of high-resolution UAV imagery to create and update cadastral maps is being increasingly investigated. Existing procedures generally involve substantial fieldwork and many manual processes. Arguably, multiple parts of UAV-based cadastral mapping workflows could be automated. Specifically, as many cadastral boundaries coincide with visible boundaries, they could be extracted automatically using image analysis methods. This study investigates the transferability of gPb contour detection, a state-of-the-art computer vision method, to remotely sensed UAV images and UAV-based cadastral mapping. Results show that the approach is transferable to UAV data and automated cadastral mapping: object contours are comprehensively detected at completeness and correctness rates of up to 80%. The detection quality is optimal when the entire scene is covered with one orthoimage, due to the global optimization of gPb contour detection. However, a balance between high completeness and correctness is hard to achieve, so a combination with area-based segmentation and further object knowledge is proposed. The localization quality exhibits the usual dependency on ground resolution. The approach has the potential to accelerate the process of general boundary delineation during the creation and updating of cadastral maps.

The integration of land administration processes and the collaboration of land agencies are considered essential for the effective delivery of developable land for housing production. The research upon which this paper is based investigates the interrelationship across land administration functions and between different levels of government in the management and delivery of land for housing production. It focuses on land management policies, land administration processes, and spatial data infrastructure, as they are related to housing production. The study starts from the premise that inadequate integration across land administration functions and between different levels of government impedes land delivery for housing production. Against this background, an assessment framework is proposed as a tool to assess the levels of integration. The parameters for the development of the framework are based on the extensive literature of past and present initiatives which focused on enhancing inter-agency collaboration. It is also supported by interviews with land agencies in the case study areas – Australia and Nigeria – to aggregate the common themes as observed in the literature. The assessment framework was evaluated through selected government departments and agencies. With this approach, the assessment framework develops into the land administration integration assessment matrix. The key consideration of the matrix is to assess the depth of inter-agency relationship ranging from information sharing to consultation, coordination of activities, joint management, partnership arrangement and formal merger of organisations.

Land as a resource is not currently managed efficiently and effectively as revealed through existing knowledge. The objective of this paper is to determine the level of this inefficiency in order to improve our understanding of the interrelationship between agencies that perform land administration functions. The research methods include a synthesis of past studies and the use of a case study approach. It uses as context Melbourne, Victoria, in Australia. This approach involves triangulation of mixed methods: interviews and on-line survey are the data sources. The Paired-Samples t-test procedure and the Pearson correlation between each pair were used for analysis. The results revealed limited integration of processes and collaboration of agencies in the management of land for housing production. The paper concludes that policies are not sufficiently informed by data and there is a noticeable disconnection between agencies and formulated policies. Invariably, land administration processes do not sufficient...

In most country contexts the activities of government land administration agencies, those dealing with the functions of land tenure, valuation, planning, and development, are disparate and lack harmonisation. This paper analyses the imperative for integrating these functions across and between government structures. An exploratory approach synthesising existing research and newly acquired empirical case study data from Victoria-Australia, and Lagos-Nigeria underpins the discussion. Drivers for interagency integration are exposed and discussed including: cost inefficiencies for actors in the development process, the effectiveness of planning enforcement, and redundancy in land information. Opportunities for integration are revealed through analysis of the land development process, land information infrastructures, and urban management policy.

Food security remains an ongoing global concern: the challenge of ensuring food availability, access, and utility for all, at all times, is yet to be met. The body of literature relating to food security is growing immensely. Land administrators are part of the discourse. Their arguments are spread disparately across academic and professional publications. The distinction between scientific work and political rhetoric is increasingly blurry: the role of land administration needs to be more concisely articulated. This paper provides a new synthesis on the relationships between land administration and food security. It undertakes a review of land administration literature relating to food security. It aims at crystallizing understandings of how land administration supports, or fails to support, food security at a conceptual level, and also the strategic and operational levels of land administration systems. The relationship between land administration and food security appears to be conceptually agreed upon; however, at operational levels the link is less evident. Conceptually, land administration is argued to deliver (and sometimes not deliver) secure land tenure, support for implementation of agricultural policies, access to credit, less litigation, easier land dealings, land taxation, land inventories, and land transaction controls. This enables (or undermines) subsistence farming, development of local agricultural sectors and markets, credit to access to non-local food markets, farm subsidization, more efficient land utilization, fairer international investments, and national food planning strategies. In general, the examined literature tends to focus on problem identification rather than system design. Additionally, the large amount of positive viewpoints need better validation in many cases. Future work needs to concentrate on examining the utility of land information and geospatial tools for food security, extracting lessons from the land administration systems of developed contexts, and improving the links at an operational level.

UAVs-unmanned aerial vehicles-facilitate data acquisition at temporal and spatial scales that still remain unachievable for traditional remote sensing platforms. However, current legal frameworks that regulate UAVs present significant barriers to research and development. To highlight the importance, impact, and diversity of UAV regulations, this paper provides an exploratory investigation of UAV regulations on the global scale. For this, the methodological approach consists of a research synthesis of UAV regulations, including a thorough literature review and a comparative analysis of national regulatory frameworks. Similarities and contrasting elements in the various national UAV regulations are explored including their statuses from the perspectives of past, present, and future trends. Since the early 2000s, countries have gradually established national legal frameworks. Although all UAV regulations have one common goal-minimizing the risks to other airspace users and to both people and property on the ground-the results reveal distinct variations in all the compared variables. Furthermore, besides the clear presence of legal frameworks, market forces such as industry design standards and reliable information about UAVs as public goods are expected to shape future developments.

Certain countries need to establish a faster, cheaper and more fit-for-purpose cadastre than those offered by conventional strategies. This paper reintroduces the strategy of the point cadastre: a cadastral system where geographic points are used to represent land parcels. When point features are combined with satellite imagery, freely available topographic maps (e.g. OpenStreetMap) and managed using cloud based geographic information services, a simple cadastral solution becomes apparent. This paper concentrates only on defining drivers and requirements for point cadastres. Three discrete studies were used to generate the requirements: expert group meetings, a pressure cooker meeting and an online questionnaire. The requirements are classified under preparation, functional, quality and architectural categories. Preparation requirements illustrate the need for contextual awareness before commencing any point cadastral project. Functional requirements are found to be similar to the requirements of ...

Existing knowledge reveals that land as a resource is not currently managed efficiently and effectively in most countries of the world. One of the factors considered important in understanding the inefficiencies and ineffectiveness is the level of integration between agencies. The objective of this paper is to determine the level of this inefficiency in order to improve our understanding of the inter-relationship between agencies that perform land administration functions. The research methods include a synthesis of past studies and the use of case study approach. It uses as context, Lagos, in Nigeria. This approach involves a mixed method: interviews and online survey. The results revealed limited integration of processes and collaboration of agencies in the management of land for housing production. We conclude that policies are not sufficiently informed by data and there is a noticeable disconnection between agencies, and formulated policies.

Over the last decade growth in spatial information use for disaster management has been considerable. Maps and spatial data are now recognized as critical elements in each of the four phases of disaster management: mitigation, preparedness, response, and recovery. The use of spatial information to support the phases of mitigation, preparedness and response to bushfires is widely understood. Less attention, however, has been given to the role of spatial information in the recovery. Moreover, the application of the spatially enabled society concept to bushfire recovery has not been explored. This paper explores the role that spatial information plays and could play in the recovery phase of a bushfire disaster. The bushfires in Victoria, Australia that took place during February 2009 are used as the primary case study. It is found that: Spatial information for recovery requires a pre-existing infrastructure; Spatial capacity must be developed across agencies dealing with recovery; Spatially enabled address and parcel information are the key dataset required to support all recovery tasks; Spatial integration of bushfire datasets (spread and intensity) require linking with planning regimes, and Spatial information that is volunteered could be incorporated into recovery activities.

The notion of using ‘natural boundaries’ to administer land and marine environments is gaining traction: a legislative study conducted upon Australian jurisdictions confirms these boundaries are being increasingly embedded into administration systems. However, the desire to utilize natural boundaries is impeded by disparate understandings of the concept. Therefore, this paper introduces a new model for understanding natural boundaries across disciplines. The study synthesizes earlier understandings of natural boundaries into an easily understood conceptual model: one flexible enough for use by practitioners from a range of disciplines, but also complex enough to enable administrative design. It is suggested all natural boundaries have five key elements: perception, purpose, presence, point-in-time and presentation. Considered together these elements help uniformly define natural boundaries. The model aims to provide a uniform description of natural boundaries for use in multi-disciplinary fields such as land and marine administration. Moreover, it will help determine what type of administrative approach is most appropriate for certain natural phenomena. While further quantitative testing is required, the model has the potential to enable multi-disciplinary discourse and to guide the design of future land and marine administrative systems.

Australian spatial sciences education is facing a paradox: the demand for graduates is steadily increasing yet enrolments remain static. This paper examines a new strategy aimed at resolving the paradox. To this end, the University of Melbourne's new degree structure and its impact on Geomatics are examined. The new model enables students to obtain a Geomatics Major within three years ‐ as part of a Science or Environments degree ‐ or a Masters in Engineering (Geomatics) within five years. Results from the first year of implementation suggest there have been increases in student quality, student engagement and the exposure of spatial sciences to undergraduates. Enrolments suggest Geomatics has halted the recent decline in numbers; however, it is too soon to determine what increases, if any, the Masters program might achieve. This paper suggests that the new model will produce both pure spatial science professionals and spatially skilled workers in other professions: both are required to combat existing sk...

Land administration systems (LAS) are now challenged by new technologies and radically different demands for land information for modern governments. Spatial information is good enough to support spatial identification and location enablement applications available in every significant type of software (word processing, spread sheets, professional applications, Web systems, GIS and databases). A place on earth can be defined with precision on the ground and in computers. Digital data can be attached to a location as never before. With appropriate computer facilities and the underpinning interpretative information layers which translate computer language into understandable descriptions of places, governments can potentially identify ‘where’ their policies are happening. A nation's ability to reap the benefits of the spatial enablement of information requires the highest level input from its government and private sectors. These challenges are discussed in the context of developing a vision of iLand, a con...

The integration of land and housing registration is a key opportunity for China: improved land governance is the intended outcome. Prior to the design of any integrated information system, the legal requirements the system must satisfy need to be identified. This paper identifies and reviews the legal requirements for the integration of land and housing information in China. Specifically, the existing legislative framework relating to land, consisting of seven levels of legislation, is interrogated. A collection of legal requirements emerges: these are categorized into themes including registration, maintenance, mortgage, transfer of real estate rights, relevant materials and archives, and preliminary notice. In order to be more applicable for the next design of the Land Administration Domain Model (LADM) country profile for China, these legal requirement are further converted into packages, classes and attributes by referring to the ISO 19152 standard. The existing databases of the Chongqing Municipality are used to support the modelling process. The paper concludes that the legal requirements can be used as a foundation for an integrated system in China.

Societal drivers including poverty eradication, gender equality, indigenous recognition, adequate housing, sustainable agriculture, food security, climate change response, and good governance, influence contemporary land administration design. Equally, the opportunities provided by technological development also influence design approaches. The Land Administration Domain Model (LADM) attempts to align both: the data model provides a standardised global vocabulary for land administration. As an international standard it can stimulate the development of software applications and may accelerate the implementation of land administration systems that support sustainability objectives. The LADM covers basic information-related components of land administration including those over land, in water, below the surface, and above the ground. The standard is an abstract, conceptual model with three packages related to: parties (people and organisations); basic administrative units, rights, responsibilities, and restrictions (ownership rights); spatial units (parcels, and the legal space of buildings and utility networks) with a sub package for surveying, and representation (geometry and topology). This paper examines the motivation, requirements and goals for developing LADM. Further, the standard itself is described and potential future maintenance. Despite being a very young standard, ‘born’ on 1st December 2012, it is already possible to observe some of the impact of LADM: examples are provided.

No jurisdiction currently maintains a fully functioning 3D cadastre. Lack of legal support, guidelines, and available technologies for acquiring and visualising 3D cadastral objects provide reasons. Additionally, the scope of 3D cadastres is wide and ambiguous with no firm agreement on the necessity and structure of 3D cadastres. Without a clear scope and vision, implementation of 3D cadastres is difficult. This paper builds from this premise. It is argued that developing a 3D cadastral data model is an effective methodology to identify and understand the scope and nature of 3D cadastres. This paper proposes a 3D cadastral data model (3DCDM). The 3DCDM provides a practical framework to model layered legal objects of survey plans and their physical counterparts using architectural and engineering plans. The data model is based on the requirements of 3D cadastre and it provides a resilient starting point for developing a 3D cadastral database.

The number of large-scale land acquisitions in developing countries has increased dramatically since 2007-2008. The phenomenon involves foreign entities purchasing or leasing vast tracts of land for agricultural or speculative gains. The size and manner of these transnational land transactions is prompting concern from international NGOs, media outlets, and other advocacy groups. Various opinions are apparent: some see the transactions as blatant ‘land grabbing’ whereby local people lose access to their lands, other argues that such transactions, if well managed, can bring much-needed capital, technology, employment, and taxation to the host countries. Despite these differences, there is growing agreement that large-scale land acquisitions require better governance. This paper aims to provide input on this front. It works from the premise that evidence-based assessment is needed. An empirical evaluation of the existing situation is undertaken. Nigeria acts as the case study: the country’s national land policy is used as the primary source for assessment. It is tested against the World Bank’s Land Governance Assessment Framework (LGAF). A range of other ‘land grabbing’ source materials including media reports, an expert questionnaire, and aerial imagery are used for validation. Overall, the results showed Nigeria fulfilled only ten (10) of the forty-four (44) dimensions examined (23%). It was found to adhere to dimensions relating to recognition of western style land rights, restrictions, and basic compensation. However, areas for policy upgrade were identified as: enforcement of existing rights; flexible methods for recognizing and registering rights (especially in rural areas); cost-effective survey mechanisms, better definition of land agency responsibilities; more equity and transparency in decision making; improving public land management; enhancing expropriation procedures; better land information collection and provision; and improved dispute resolution processes. The LGAF was found to be a useful diagnostic tool, however, it is recommended that a set of guidelines specific to large-scale land acquisitions be developed.
