Climate resilient spatial plans: Revised LADM climate adaptation profile

Resumo

In 2022, the Netherlands introduced ‘water and soil’ guidance as key principle for Dutch spatial planning. This approach emphasizes water and soil considerations into planning processes, especially when addressing pressing climate challenges in the country, such as flooding, rising sea levels, and soil subsidence. However, its implementation has encountered significant obstacles, particularly in the areas of data accessibility, standardization, and interoperability. Despise their availability, geological and hydrological information is often specialized, fragmented into multiple sources, and overall still unused in spatial planning. To address these challenges, the Land Administration Domain Model (LADM) Part 5 climate adaptation profile was introduced in 2024 and incorporated as Annex C in the ISO 19152-5 standard. This specialization profile provides a structured framework to integrate subsurface and climate-related data into land administration systems, enabling planners to make informed decisions and share plan information to support climate adaptation. The initial profile received valuable feedback from spatial planners, who highlighted the need for better integration with external data sources, improved data traceability, and design flexibility. This paper presents a revised version of the LADM climate adaptation profile, incorporating key modifications to address the feedback and enhance its functionality. One significant update is the inclusion of external classes, facilitating integration with external data sources, such as geological and hydrological models, and climate projections. Additionally, the revised profile includes the LA_Source class to meet spatial planners’ requests for data traceability. To demonstrate the revised LADM profile, real Dutch plan information is used. For instance, one case study demonstrates how the LADM profile facilitates subsurface assessment during the masterplan phase, by integrating groundwater data and geological models with land use plans. The examples highlight the profile’s ability to bridge theoretical frameworks with practical implementation, supporting the Netherlands’ ‘water and soil’ principle. In short, the revised LADM Part 5 climate adaptation profile strengthens Dutch efforts to achieve climate resilience by improving data integration, transparency, and decision-making. Its flexible and interoperable framework also holds promise for global adoption. As nations worldwide seek to balance spatial development with climate adaptation, the profile’s standardized approach can inform international best practices.
