SAUCEDO, J. et al. Arreglos silvopastoriles con especie arbórea Alnus acuminata (aliso) y su efecto sobre los factores ambientales de sistemas ganaderos. RIA. Rev. investig. agropecu. [online]. 2020, vol.46, n.3, pp.323-328. ISSN 1669-2314.

Silvopastoral systems constitute sustainable production systems and also an alternative that not only serves to mitigate the effect of climate change, but also to adapt to it. The objective of this study was to evaluate the effect of silvopastoral arrangements with Alnus acuminata (trees in alleys, scattered trees in paddocks, living fences) on environmental factors such as temperature and relative humidity. The evaluations were carried out in four locations in the district of Molinopampa (Molinopampa, Santa Cruz del Tingo, Pumahermana and Ocol), Amazonas region (Peru); during the period from November 2016 to October 2017. Sixteen paddocks with homogeneity in age and density of trees, and fodder component, established under a randomized complete blocks design, were considered. The data were recorded with a frequency of four hours and processed by the Kruskal-Wallis and Mann-Whitney U tests in pairs (p <0.05). The results show the existence of statistical differences for temperature and relative humidity of the silvopastoral and open field systems. Arrangements with trees in alleys registered less variation of temperature and relative humidity of the air, allowing to generate a favorable microclimate for the development of the forage component and the comfort of the livestock; they also minimize the effect of climate change.
