PONVERT-DELISLES BATISTA, Dámaso R. Some considerations on the behavior of the agricultural drought in the cuban agriculture and the use of satellite images in its evaluation. cultrop [online]. 2016, vol.37, n.3, pp. 22-41. ISSN 1819-4087.  http://dx.doi.org/10.13140/RG.2.1.4591.3843.

The agricultural drought has been classified as a “Silent disaster” that causes considerable impacts in the agricultural systems: in cultivations, grassland, livestock, soils dedicated to the production, etc. But not only in the agriculture, this also caused negative effects in the population, the economy and the environment. Their fundamental causes are given by the shortage of atmospheric humidity, the inadequacy of generating systems of rain or the persistence of a strong subsidence, or, to the combination of some of these factors whose should be studied in the context of the atmosphere general circulation. In Cuba, different events of droughts have taken place during long time that have been affected territories of almost the whole country causing millionaire losses for the impact in the agricultural production and environmental ecosystems, reason for which becomes necessary to know and to study the causes, the behavior and consequences of such phenomena, in order to create policies and confrontation strategies and early warning with a view to reduce and to mitigate their impacts and to guarantee the environmental sostenibility and the alimentary security. Given this background, the present work has the aim to show the state of this topic art through a series of aspects allow to characterize the behavior of this hydrometeorological phenomenon in our country and to international scale, highlighting the use of satellite images in its evaluation which constitutes an effective technological tool for its study and evaluation
