This presentation focuses on the FAO56 approach, which describes reference evapotranspiration and crop evapotranspiration methodologies. At the same time, the presentation discusses some crop and soil characteristics such as the use of growing degreedays for setting the crop growth stages dates, the fraction of ground cover, root depth, field capacity, etc., to assess the crop water requirements.

This presentation shows how to estimate evapotranspiration using remote sensing approaches.Two methodologies were discussed. One methodology combines the FAO56 approach and the spectral vegetation indexes (VIs) obtained by satellite images to estimate basal crop coefficient (Kcb). The other methodology is based on the Surface Energy Balance (SEB) and uses remote sensing data as input.

This presentation focuses on intensive irrigated agriculture and environmental pollution issues, mainly nitrate leaching into the water bodies. Two case studies are presented – olive orchard and maize field with drip and center pivot irrigation, respectively – and assessed using modelling through soil water balance and soil nitrogen balance.

This presentation focuses on the methodology that can be applied to model water irrigation requirements in the context of climate change. The theoretical part was followed by the presentation of the different case studies, for different crops, from Portugal. In these case studies the climate change impacts expected are i) increase in the irrigation requirements; ii) water deficit of the rainfed crops and iii) irrigation system design – increase peak flows and in pipe diameters.

This hands-on presentation discusses a simplified methodology for estimating leaf stomatal density under different levels of water stress. The main topics covered were the care for
collecting the leaf, the time of collection, the preparation of the leaf with the placement of nail polish, the gluing of the tape to the leaf, the removal of the tape and gluing on the slide, the observation in the microscope and the counting of the stomata.

This practical session referred to calculate spectral vegetation indexes and basal crop coefficients over an agriculture field, using data from Sentinel-2 satellite images. This activity uses satellite images of Sentinel-2 on QGIS software to estimate Kcb values across the Butmir and Aleksandrovac regions, in Bosnia and Herzegovina.

To improve agricultural management such as water and nitrogen inputs, remote sensing images and indexes can be used. As an example, it is presented a case study developed in South Italy with some objectives for instance: i) integrating information derived from soil and crop proximal
sensors, ii) characterize soil spatial variability, iii) investigate relationship between hyperspectral VIs and both biometric and physiological crop parameters to increase the precision and sustainability of crop production.

In this session some opportunities for collaborative projects in Western Balkans countries are presented, provided by the European Research Council. The European Union strategic framework is based on six political priorities such as i) a European green deal; ii) an economy that works for people; iii) a Europe fit for the digital age; iv) protecting our European way of life; v) a stronger Europe in the world and vi) a new push for European Democracy.
