During the FOSS4G Europe 2024 Conference on 3 July Alexander Kmoch presented his manuscript on XDGGS. Recording of the presentation can be accessed here or below.

Traditional map projections introduce distortions, especially for global data. Discrete Global Grid Systems (DGGS) offer an alternative by dividing the Earth into equal-area grid cells at different resolutions.

This paper describes xdggs, a new Xarray extension that simplifies working with DGGS. Xdggs provides a unified API for various DGGS libraries and integrates seamlessly with the Pangeo ecosystem through extending the widely used Xarray library to use the DGGS-specific cell identifiers as an index. This development makes DGGS more accessible and will lead to facilitating data analysis on a planetary scale.

The European Research Council (ERC) has awarded Evelyn Uuemaa, Professor of Geoinformatics at the University of Tartu, the Consolidator Grant to develop models based on remote sensing data and machine learning that will enable both farmers and policymakers to plan nature-based solutions in the landscape to mitigate the negative environmental impact of intensive agriculture.

The rapid growth of the world’s population has increased the demand for intensive agriculture. Unfortunately, this often comes with negative environmental impacts. This is why more and more people are looking for new ways of sustainable agriculture, where the environmental impact is reduced as yields increase. Nature-based solutions, such as wetlands and riparian buffer strips along watercourses, can effectively reduce nutrient (nitrogen and phosphorus) runoff from agricultural catchments. However, it is neither economically viable nor, in most cases, naturally feasible to establish them throughout the landscape. It is therefore important to identify priority areas in the landscape when planning nature-based solutions, making smart use of spatial data.
