Uncertainties in agricultural activities due to the scarcity of water and the increase in droughts could be ameliorated by considering early detection and spatio-temporal characterization of water stress conditions at a regional scale from remote sensing.
ILWIS for Windows is a Windows-based, integrated GIS and Remote Sensing application consisting of: (i) Display of raster and multiple vector maps in map windows; (ii) Display of tables in table windows; (iii) Interactive retrieval of attribute information, (iv) Image processing facilities, (v) Ma
In the evaluation of the onset, severity and duration of situations of water stress and droughts, indicators based on processes with intensive use of remote sensing can be used.
The encroachment of woody species in natural grasslands has recently increased, especially in arid and semi-arid environments.
Ranching generally causes a progressive deforestation. Nevertheless in Mediterranean countries trees are still present in many pastoral systems, here referred to as silvopastoral systems (SPs).
Portugal has voluntarily committed to reporting the CO2 emissions and removals resulting from grassland management under Kyoto Protocol Article 3.4.
The goal of this paper is to illustrate how INSPIRE can facilitate orientation and advice to calculate the water requirements of crops. These technologies can provide information adapted to specific conditions, updated daily and in an interactive way.
The potential of remote sensing for the recommendation and monitoring of irrigation practices is irrefutable.
Grasslands are one of the world's most widespread vegetation types, covering nearly 20% of the land surface and represent a major source of production of agricultural products. However, grassland vegetation across the Mediterranean region is changing at an unanticipated rate.
