In spite of recent advances in the provision of accurate
environmental data over the globe from satellite data and other
sources, there is still a lack of comparable high resolution soil
data. Detailed soil information exists for only a small fraction
of the globe. The last major effort to produce global coverage of
soil maps dates back to 1974, with the publication of the FAO soil
map of the world, hence soil data now lags seriously behind
information of comparable environmental attributes.
Soil maps lack not just precision, but accuracy. Conventional soil
maps use concepts that lack at least 50 years. They are predominantly
qualitative, and depend on poorly specified predictive models that
are not updatable.
The International Center for Tropical Agriculture (CIAT) is
interested in improving the quality of soil maps for the tropics,
therefore improving its ability to:
- visualize catchment hydrology at a scale amenable to
community-based management
- help target soil-sensitive crops confidently within new areas
- help explain complex patterns of changing land use that
underwrite landscape resilience.
The proposed work will explore ways to use the knowledge of the
scientists at CIAT and existing GIS data to create soil models for
the tropics using artificial intelligence, machine learning and/or
data mining techniques.
