Application of LADM for disaster prone areas and communities

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.     

An evaluation framework for earthquake-responsive land administration

In recent years earthquakes and their secondary hazards have claimed the largest number of lives of all large natural disasters. Some of the world’s most earthquake-prone zones are also areas of high population density. The impact is magnified by vulnerability factors including non-enforcement of building codes, knowledge gaps, urban poverty and poor governance capacity to manage and reduce earthquake risks. Poor security of land tenure and property rights increases the vulnerability of people and affects their ability to respond to natural disasters.Earthquake recovery and reconstruction provides very significant challenges for land agencies, with these challenges differing from one country to the next due to differences in the local context. Drawing on contrasting case studies in Haiti, Nepal and New Zealand this paper identifies the common post-earthquake land administration functions and challenges that may apply to many contexts. These lessons provide land agencies and other key stakeholders with a summary of the challenges an earthquake poses for land administration at different post-disaster stages. We also discuss the policy and regulatory, institutional, operational and preparedness lessons for land administration. From these lessons we propose a framework for evaluating the earthquake-responsiveness of a land administration system. This framework can be used by a land agency in an earthquake prone region, or where an earthquake has recently occurred, to assess what challenges to land administration might occur in the event of an earthquake, and the preparedness of their land administration system.     

Urban land management in China: A study of the present system and an investigation of current issues and problems

Summary

The paper commences by describing the statutory basis for land tenure and management. It examines the constitutional basis for land ownership and occupation rights, as amended by land administration law. The legal system and procedures at both central and local government level are introduced, with particular mention made of the special measures for land requisition. This is followed by a study of the organizational structure for land management in China at state and local government levels. The roles and responsibilities of the major agencies of government at both levels are explained, and related to the organization of urban planning. A separate section is then devoted to those areas such as Special Economic Zones and Open Coastal Cities which have been selected for preferential treatment, particularly in respect of the transfer of land use rights.

The paper concludes with a study of the main issues and problems that currently confront China in the field of urban land management. And some suggestions are made where further reform is required and additional research of potential benefit.     

Application of LADM for the integration of land and housing information in China: The legal dimension

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.     

Perceptions of public land governance from two Canadian provinces: How is the social agenda being met through sustainable forest management?

This article presents a comparative assessment of current spaces for public involvement in Crown (public) land management in the Canadian provinces of New Brunswick and Nova Scotia. More specifically, it addresses the barriers to public participation by examining the agency-client relationship – specifically, through the theoretical lens of capture – as an impediment to the inclusion of values that are outside the traditional, technocratic management realm of public forest management. Without public input, the public’s needs, values, and desires are not articulated and the social side of sustainable forest management is likely to be neglected. Low levels of trust in public land management agencies in New Brunswick and Nova Scotia, coupled with minimal space for public involvement, have created the perception of a policy network that is dominated by industry and/or government and provides minimal space for other interests. The primary research method is an online survey informed by forty-two interviews. The survey was administered to 89 key forestry stakeholders in New Brunswick and Nova Scotia. Participation observation and a document analysis are utilized to complement the survey. This research finds that (1) although survey participants come from diverse affiliations and two provinces with different forest policy and unique approaches to public participation, there is essential consensus of the need for an improvement of public involvement processes for public land; (2) trust in the forest industry and the Department of Natural Resources (DNR) is extremely low in both provinces. Even with recent participatory efforts in Nova Scotia, the trust level is lower than in the neighboring province of New Brunswick. Some participants connect this distrust to privileged access for certain interest groups and a closed policy network; (3) barriers to participatory processes differ between provinces, especially a fear of retribution, which is specific to New Brunswick; and (4) key stakeholders identify barriers to engagement that they perceive to be different for themselves and the general public.     

Supply side constraints in the Israeli housing market—The impact of state owned land

House prices in Israel have risen since 2008 by as much as 98%. Much of this increase is attributed to low levels of housing supply and housing supply elasticities. In Israel land is frequently owned by the state. This results in heavy government involvement in the housing market through the control of land supply via land tenders. This paper estimates the impact of state owned land on the Israeli housing market focusing on these unusual conditions of land supply. A model for the creation of new housing units is proposed. This incorporates land tenders, enabling the estimation of housing supply dynamics with an accurate measure of public land supply. The model is tested using regional panel data which facilitates the dynamic estimation of national and local supply elasticities and regional spillovers. The paper uses novel data sources resulting in a panel of 45 spatial units over a span of 11 years (2002–2012). Due to the nonstationary nature of the data, spatial panel cointegration methods are used. The empirical results yield estimates of housing supply price elasticities and elasticities with respect to land supply. Results show that housing supply is positively impacted by governmental decisions but the impact is low. Supply elasticity with regard to government land tenders stands at around 0.05 over the short run and 0.08 over the long run. Government policy of offering land in low demand areas and fixing minimum-price tendering does not seem to affect housing supply. Policy implications point to the need for more sensitive management of the delicate balance between public and private source of land in order to mitigate the excesses of demand shocks.     

Quantitative micro-scale flood risk assessment in a section of the Trotuș River,Romania

This paper focuses on the estimation of direct damages caused by three flood scenarios with different return periods in the section Făgetul de Sus – Ghimeş – Palanca Pass of Trotuș River, with the aim of highlighting the need of improved land use plans. The damage for three land use classes (residential building, infrastructure and agriculture) were estimated using the damage curves developed by the European Joint Research Centre (JRC) as well as site specific maximum damage values. The data were processed with the help of the ArcMap 10.2 software and FloodRisk tool from QGIS software. Furthermore, the flood risk was assessed using the damage – probability curves, which associates the damage with the corresponding frequency of occurrence. This method was identified and adapted to the characteristics of the study area in order to develop a methodology of flood risk assessment that is answering the question: does the lack of land use plans increase the vulnerability and the flood damage? The results showed that the greatest damages are registered for the residential building land use class for a flood probability of 0.001. In this case the damages reach up to 60% on the scale range of deterioration factor, the total damage value being 2 million euros. For the same hazard probability the total registered damage value for roads is 7500 euro, for railways is around 12,000 euro, while for agriculture is around 84,000 euro. These results highlight the need of protection measures and land use plans development and implementation. Regarding the protection measures we consider that the egalitarianism would be the concept that should be applied in the study area and also an improved cooperation between government, specialized agencies and local authorities at local level would lead to a more efficient flood risk management process. The proposed methodology can be applied for micro-scale analysis, providing quantitative results regarding the flood damage and flood risk assessment. It includes a detailed vulnerability analysis of the elements-at-risk with the aim of developing a more comprehensive approach of flood risk assessment.     

Facilitating collaboration in forest management: Assessing the benefits of collaborative policy innovations

Collaborative governance and landscape approaches have become a more prevalent in public land management in the United States in the face of increasing ecological and societal complexity and decreasing government resources and capacity. In this era of devolution and social-ecological change, there is a growing need for policy approaches that facilitate partnerships and participatory approaches to land management. One unique policy that emphasizes collaboration and large-landscape restoration on US federal forestlands is the Collaborative Forest Landscape Restoration Program (CFLRP), established in 2009 to accelerate the pace and scale of forest restoration. The policy included novel characteristics such as a decade-long commitment to landscapes and formal requirements for collaboration. This program presented an opportunity to assess how this policy affected collaboration and the factors that led to differential policy implementation. We conducted 89 interviews across all 23 CFLRP projects with internal agency staff and external collaborators on each project. We found that the CFLRP generated a variety of benefits related to collaboration, including increased trust and stronger relationships, increased collaborative partner influence, decreased litigation and conflict, and increased capacity to accomplish work; however, there were also challenges associated with the program, including thetime-intensive nature of collaboration and the lack of industry or contractors. Various local factors affected collaborative outcomes under the policy, including staff turnover and capacity, local leadership, and collaborative history. Successful collaborative outcomes were widespread under the CFLRP, and from this, we draw implications for the broader environmental governance literature about the policy characteristics that facilitate collaboration and the other institutional variables that may require attention in this context.

Housing development in Australia: The implications of production and approval processes for availability and choice

Summary

This paper focuses on the housing production and development approval processes: the agencies involved and the implications for the product, housing, in terms of costs and design. Changing household structure, expansion of metropolitan areas and rising costs (financial and social) mean that the traditional style of single storey detached homes no longer provides adequate choice. An investigation into housing costs in 1978, found that the land development process and approval procedures were major contributors to both inefficiencies in production and conservative attitudes inhibiting the diffusion of new ideas and alternative dwelling choices. The paper reviews changes which have taken place during the 1980s especially in the role of the states in land development, changes in approval processes (planning, subdivision and titling) and more effective use of land by improved design and layout. These are examined against a background of the uniqueness of the Australian housing system with its emphasis on owner‐occupation and which in common with Britain has an increasing affordability problem. The roles of landowners, speculators, developers (including the state land authorities), housebuilders and house‐owners are examined together with some of the factors affecting availability and choice.

Land reallocation reform in rural China: A behavioral economics perspective

Based on prospect theory, we develop a theoretical framework to unify divided views on land reallocation reform in China. Our theoretical framework and empirical verification explain the driving forces behind the success of the rural land reallocation reform in China. We find that rural land reallocation reform in China is characterized by induced and imposed institutional changes. The relationship between induced and imposed institutional change is complementary instead of competing. The decision and frequency of land reallocation are affected by both local endowment and central government policy. Empirical findings also suggest that land reallocation reform in China is incremental, with interim policy targets from different stages taking gradual effect. The incremental implementation of the “No Reallocation” policy is the reason behind the widespread, diversified land reallocation practices across the country; this policy also contributes to the success of rural land reform in China. The theoretical model can be used to study a wide range of government-led institutional changes in China, such as affordable housing schemes and the National New-type Urbanization Plan (2014–2020).     

Integrating decentralised land administration systems with traditional land governance institutions in Ghana: Policy and praxis

The aim of the Land Administration Project (LAP) policy reform for supporting the establishment of the Customary Land Secretariats (CLSs) is to formalise and strengthen customary land administration and management within the context of decentralised land administration. With the prospects of the CLSs becoming the legal local land administrative units, the paper assessed how traditional land governance institutions may have contributed to the decentralisation of land administration in Ghana. The research used case study strategy within the qualitative research paradigm and un-structured questionnaires were used to collect data. The analyses show that, simple land registries exist with traditional local governance institutions through the CLSs. The maintenance and effectiveness of this however depends on continuous improvement of records keeping, quality of office personnel and suitable office accommodation. This should be devoid of local power struggles among current and successive chiefs. Also, collaboration with public land sector agencies especially in areas of sharing information on rights, uses, disputes and preparation of planning layouts is paramount. These registries are mere extension of the state land administration apparatus as service units under the deconcentration of land administration powers. The paper concludes that the current policy focus on strengthening decentralised land administration through the CLSs may fail if attention is not given to the maintenance of the local registries. Revenue generation capacities of the CLSs need to be enhanced in order for them to recruit and maintain quality office staff, and acquire technical logistics. Decentralising land administration to the CLSs under the deconcentration of powers should be maintained in the interim because of the teething problems identified with this current system.     

An assessment framework for public urban land management intervention

The ability to manage land effectively depends on the availability of accurate and up to date information on it. Many cities, particularly those in the developing world, lack the means to generate the information needed to support land management. This paper proposes the use of assessment studies as a mechanism to generate information for land management. A model of the public land management system and a framework of steps and issues for carrying out an assessment study are presented. The paper also presents an overview of the common problems of land management in the developing world and a case study to illustrate the utility of the proposed framework.
