Special issue: Soil & Land Information
In this issue
In this 20th issue of Soil Horizons we highlight our latest advances in the collection, use and sharing of nationally important soil and land resource data.
Land Resource Information: A strategic roadmap for the future
Landcare Research, like all the Crown Research Institutes, has agreed a Statement of Core Purpose in partnership with stakeholders and shareholders, mapping out where and how our science can deliver national benefit.
Supplying land and soils data over the web – the LRIS portal
Access to the national Land Resource Inventory (LRI) has been transformed through the use of Internet and ‘Google Earth’ style technologies.
S-map Online: an interactive mapping and query application for New Zealand soils data
S-map is a new digital soil spatial information system for New Zealand created as part of the government-funded SpInfo (Spatial Information) programme run by Landcare Research.
New Zealand Soil Classification updated and extended
A number of new soils have been recognised in New Zealand and are published in a new edition of the Soil Classification in New Zealand (Hewitt 2010).
New Zealand – part of GlobalSoilMap.net
A global consortium has been formed that aims to make a new digital soil map of the world. Data for 11 key soil attributes will be modelled for 6 soil depth increments and mapped at 90-m resolution.
Ecosystem Services for multiple outcomes
Communities not only require their environment to provide food and drink but also shelter, livelihoods, lifestyle, and access to goods. These components of human well-being are provided directly and indirectly by both managed and natural ecosystems.
Detecting changes in soil carbon and nitrogen under pastoral land use in New Zealand
We have revisited and resampled the National Soils Database sites to compare changes in soil carbon, nitrogen, phosphorus, and pH since archived samples were collected (dating back to 1960s).
Making better use of LiDAR in soil and landscape modelling
LiDAR (Light Detection And Ranging) is a remote sensing technique that uses high-frequency laser pulses to gather information about a surface. A LiDAR survey may contain multiple points per square metre over very large areas with vertical accuracies of 0.15 m or even better, enabling the generation of very high resolution Digital Elevation Models (DEMs).
Tracking the depth to water table in the Manawatu Sand Country
We are using a wireless network of sensors installed in the ground to monitor soil moisture and depth to water table at our research site in the Manawatu Sand Country.
Effect of erosion on soil carbon stocks
Since the development of the Soil Carbon Monitoring System (Soil CMS) to predict soil carbon stocks, it has been recognised that mass movement erosion potentially has a major influence on these stocks.
Protecting coral reefs in the Pacific
News media report regularly on the threats to coral reefs from climate warming. However, sedimentation from adjacent catchments onto near-shore coral is a more visible impact for Pacific Island communities who rely on these coral reefs for fish, tourism, and maintaining traditional cultural values.
Mapping Antarctic soils
The Antarctic environment and its soils are protected by international treaty that gives freedom for scientific investigation and sets stringent standards of environmental protection.
New editions of the NZ Land Cover Database
How and where is land cover in New Zealand changing through time? What are the major characteristics of this change? These two key questions will be answered by new editions of the New Zealand Land Cover Database (LCDB).
