Domingo Alcaraz-Segura in OpenAIREKnowing the extent and environmental drivers of forests is key to successfully restore degraded ecosystems, and to mitigate climate change and desertification impacts using tree planting. Water availability is the main limiting factor for the development of forests in drylands, yet the importance of groundwater resources and palaeoclimate as drivers of their current distribution has been neglected. Here we report that mid-Holocene climates and aquifer trends are key predictors of the distribution of dryland forests worldwide. We also updated the global extent of dryland forests to 1,283 million hectares and showed that failing to consider past climates and aquifers has resulted in ignoring or misplacing up to 130 million hectares of forests in drylands. Our findings highlight the importance of a wetter past and well-preserved aquifers to explain the current distribution of dryland forests, and can guide restoration actions by avoiding unsuitable areas for tree establishment in a drier world.

Siham Tabik in OpenAIREAbstractThis study presents a new functionality of Geographic Information Systems (GIS) to assess solar energy input on vast high resolution Digital Elevation Models (DEMs). This tool is able to find out 1) the maximum solar energy that can be captured on a surface situated at a determined hight on each point of the DEM and 2) the optimal angles (i.e., slope and orientation) that allow capturing this maximum energy. Insolator: the open source high performance solar radiation model, we developed in a previous work, is used as baseline for this tool. Contrarily to most existent GIS tools, the proposed algorithm doesn’t suffer memory limitations and is specially suitable for GPU-CPU heterogeneous systems. The experimental results show that the proposed algorithm is able to compute the maximum irradiation and optimal angles maps on large DEMs with high accuracy in very short times and showing a high scalability.

Siham Tabik in OpenAIREThis paper presents a fast algorithm to compute the global clear-sky irradiation, appropriate for extended high-resolution Digital Elevation Models (DEMs). The latest equations published in the European Solar Radiation Atlas (ESRA) have been used as a starting point for the proposed model and solved using a numerical method. A new calculation reordering has been performed to (1) substantially diminish the computational requirements, and (2) to reduce dependence on both, the DEM size and the simulated period, i.e., the period during which the irradiation is calculated. All relevant parameters related to shadowing, atmospheric, and climatological factors have been considered. The computational results demonstrate that the obtained implementation is faster by many orders of magnitude than all existing advanced irradiation models while maintaining accuracy. Although this paper focuses on the clear-sky irradiation, the developed software also computes the global irradiation applying a filter that considers the clear-sky index.
