Condiciones hidrotérmicas relevantes para la zonificación de plantaciones de balsa (Ochroma Pyramidale (Cav. Ex Lam.) urb.) en la provincia los Ríos.

Climate variations intensified by climate change have determined serious impacts on forest systems in general. Droughts, floods, fires and pests in multiple regions have increased, triggering climate alarm systems to mitigate or eliminate damage to forest systems. The objective of this research was to evaluate the agroclimatic conditions of the Ochroma pyramidale (Balsa) in order to determine the favorable periods for the development of this species, the impact of environmental services from the climate and the differentiation of the areas according to their agroclimatic potential for satisfying the requirements of the species in question. The decadal data of the maximum and minimum temperatures for a period of 30 years were taken in 30 real and virtual stations. Decadal maximum and minimum temperature matrices were created and the average temperature matrix was obtained. The same procedure was applied to obtain a matrix of the sum of decadal precipitations. With the data of the average temperatures and accumulated rainfall, maps of average temperatures and accumulated rainfall were obtained. The AgroclimMap software was applied, which produces maps of the thermal and rainfall conditions and evaluates the favorable conditions for Ochroma pyramidale (Balsa) by algebraic operations, categorizing the regions as Favorable, Moderately Favorable and Not favorable. 38% of the province presented favorable conditions for the development of Ochroma pyramidale in relation to the sum of annual rainfall. The sectors are: Babahoyo, Pichilingue, Ventanas, Quinsaloma, Quevedo, Buena Fe, Los Angeles and Mocache. The remaining sectors are located in the Moderately Favorable with 62% of the territory. Unfavorable conditions are not present in the territory. The results of the 25th Percentile for the sum of annual precipitations of 1295 mm are located in the Unfavorable conditions, with moderately probable conditions for drought events. On the other hand, the 75th Percentile exceeds the maximum requirement of the raft by 180 mm, which makes it unlikely to reach that condition. It is recommended to extend similar studies to other provinces dedicated to the exploitation of forest areas. Keyword: agroclimatic characterization, precipitation, temperature, raft
