- Space distribution of Pennisetum purpureum, according to projections for climate change in Cuba A. Álvarez-Adán G. Febles J. M. Fernández Agrociencias Future climates space distribution Pennisetum purpureum In order to determine the future space distribution of Pennisetum purpureum, according to projections of climate change for Cuba, with the purpose of contributing to take proper decisions regarding future management of this species and to establish efficient regulations for its adaptation to the influence of climate change, a general methodology of analysis was designed that combined the information of mean annual temperature and precipitation, type of soil, pH, and irrigation with the implementation of space analysis operations: filtration and map superposition to achieve space distribution. Therefore, daily outputs of the General Circulation Model Echan4 were used with forcing of emission scenarios A2 and B2, for the analysis of future climates. It was confirmed that, according to soil potential, only 34% of Cuban territory may be used for the cultivation of the studied species. In addition, there was a tendency to decrease the areas with potential of precipitationtemperature, favorable for the development and growth of this species. A2 scenario was the most critical. Negative anomalies increased up to 64 and 59% for A2 and B2, respectively. It is concluded that integration of physical, climate and soil factors allowed the identification of potentially usable areas for cultivation and development of this species. 2016 artículo científico 0034-7485 https://www.redalyc.org/articulo.oa?id=193048877014 en http://www.redalyc.org/revista.oa?id=1930 Revista Cubana de Ciencia Agrícola application/pdf Instituto de Ciencia Animal Revista Cubana de Ciencia Agrícola (Cuba) Num.2 Vol.50
