Towards Responsible Consolidation of Customary Lands: A Research Synthesis

The use of land consolidation on customary lands has been limited, though land fragmentation persists. Land fragmentation on customary lands has two main causes—the nature of the customary land tenure system, and the somewhat linked agricultural system. Since attempts to increase food productivity on customary lands have involved fertilisation and mechanisation on the small and scattered farmlands, these approaches have fallen short of increasing food productivity. A study to develop a responsible approach to land consolidation on customary lands using a design research approach is undertaken and reported here. Based on a comparative study, it is found that three factors inhibit the development of a responsible land consolidation approach on customary lands—the coverage of a land administration system, a land valuation approach, and a land reallocation approach the fits the customary land tenure system. To fill these gaps, firstly, this study developed the participatory land administration that brought together traditional land administration approaches with emerging bottom-up approaches, as well as technological advances that drive these approaches together with the growing societal needs. Secondly, a valuation approach was developed to enable the comparison of the farmlands in rural areas that are without land markets. Finally, a land reallocation approach was developed based on the political, economic and social, as well as technical and legal characteristics of rural customary farmlands. This study concludes that though the land consolidation strategy developed is significantly able to reduce land fragmentation, both physical and land tenure, the local customs are an obstruction to the technical processes to achieve the best form of farmland structures

Groundwater management in land administration: a spatio-temporal perspective

Although the use of land and water is intertwined, specifics for groundwater management are not effectively dealt with in the laws and other institutional mechanisms related to land. Provisions for groundwater aspects in land management are there, but with a focus on the land itself. Land rights and restrictions are more or less static, lacking enough flexibility to incorporate the relatively short interval spatio-temporal dynamics of groundwater resources in the land management and regulation mechanisms. This leads to a gap between the scientific inputs and policy-decision making. The paper suggests the adaptation of a spatial information science based approach to bridge the gap between the technical and administrative aspects of groundwater management. The land administration domain model (LADM) provides a basic set of elements capable of supporting the inclusion of basic groundwater modeling elements into land administration, making it possible to create a support system for the management of land and water. For this purpose, spatial and temporal dimensions under the legal-administrative and spatial unit components of the standard LADM model are reviewed. The paper shows that the advancement of spatial technologies is capable of providing solutions for global issues such as groundwater resource management. As a first step towards implementation of these technologies, it is essential to include spatio-temporal dynamics properly in the standard data models. Increased knowledge of the behaviour of groundwater resources, supported by a technical system built on a land administration counterpart, could help improve greater sustainability in the use of such resources. Considering the specific arrangements of rights, parties and spatial units this could, if desired, also provide the base for a regulated private market in groundwater assets. Further research will be needed to fully operationalize and implement such data models, which ultimately could produce outputs at case study level which can help to formulate policies regarding natural resources more on the basis of technical inputs

Meeting the 2030 Agenda:Responsible Consolidation of Ghana's Customary Lands

Land Consolidation on Sub-Saharan Africa’s customary lands have generally failed for various reasons. However, with the prevalence of land fragmentation as a problem in the past two decades, there has been a new wave of land consolidation activities in the region. Land fragmentation on customary lands has two main causes—the nature of the customary land tenure system, and the somewhat linked agricultural system. Since attempts to increase food productivity on customary lands have involved fertilisation and mechanisation on the small and scattered farmlands, these approaches have fallen short of increasing food productivity. Land tenure security is further low on these lands. This study examines how a responsible land consolidation measure can be developed for customary lands to contribute to food security and land tenure security. A design research approach is used to develop a land consolidation measure for customary lands and reported here. This study concludes that though the land consolidation strategy developed is significantly able to reduce land fragmentation, both physical and land tenure, the local customs are an obstruction to the technical processes to achieve the best form of farmland structures. Hence the developed approach can contribute to land tenure and food security

Upgrading Spatial Cadastres in Australia and New Zealand: Functions, Benefits & Optimal Spatial Uncertainty

Successful economies rely on effective land administration and cadastral systems.The Cadastre 2034 strategies of Australia and New Zealand jointly seek to provide “a cadastral system that enables people to readily and confidently identify the location and extent of all rights, restrictions and responsibilities related to land and real property”. An important component of each jurisdiction’s cadastral system is the ‘Spatial Cadastre’; being a geo-located spatial representation of cadastral boundaries in that jurisdiction. This is delivered online to an increasingly wide variety of users and serves multiple purposes. Spatial Cadastres that are fit-for-purpose will be critical to achieving the Cadastre 2034 strategies

Making the third dimension (3D) explicit in hedonic price modelling : A case study of Xi’an, China

Recent rapid population growth and increasing urbanisation have led to fast vertical developments in urban areas. Therefore, in the context of the dynamic property market, factors related to the third dimension (3D) need to be considered. Current hedonic price modelling (HPM) studies have little explicit consideration for the third dimension, which may have a significant influence on modelling property values in complex urban environments. Therefore, our research aims to narrow the cognitive gap of the missing third dimension by assessing both 2D and 3D HPM and identifying important 3D factors for spatial analysis and visualisation in the selected study area, Xi’an, China. The statistical methods we used for 2D HPM are ordinary least squares (OLS) and geographically weighted regression (GWR). In 2D HPM, they both have very low R2 (0.111 in OLS and 0.217 in GWR), showing a very limited generalisation potential. However, a significant improvement is observed when adding 3D factors, namely view quality, sky view factor (SVF), sunlight and property orientation. The obtained higher R2 (0.414) shows the importance of the third dimension or—3D factors for HPM. Our findings demonstrate the necessity to include such factors into HPM and to develop 3D models with a higher level of details (LoD) to serve more purposes such as fair property taxation. © 2020 by the authors.

Data Model for the Collaboration between Land Administration Systems and Agricultural Land Parcel Identification Systems

The Common Agricultural Policy (CAP) of the European Union (EU) has dramatically changed after 1992, and from then on forward the CAP focussed on the management of direct income subsidies instead of production-based subsidies. For this purpose, Member States (MS) are expected to establish Integrated Administration and Control System (IACS), including a Land Parcel Identification System (LPIS) as the spatial part of IACS. Different MS have chosen different solutions for their LPIS. Currently, some MS based their IACS/LPIS on data from their Land Administration Systems (LAS), and many others use purpose built special systems for their IACS/LPIS. The issue with different IACS/LPIS is that they do not have standardized structures; rather, each represents a unique design in each MS, both in the case of LAS or special systems. In this study, we aim at designing a core data model for those IACS/LPIS based on LAS. For this purpose, we make use of the ongoing standardization initiatives for LAS (Land Administration Domain Model: LADM) and IACS/LPIS (LPIS Core Model: LCM). The data model we propose in this study implies the collaboration between LADM and LCM and includes some extensions. Some basic issues with the collaboration model are discussed within this study: registration of farmers, land use rights and farming limitations, geometry/topology, temporal data management etc. For further explanation of the model structure, sample instance level diagrams illustrating some typical situations are included.
