Influence of climatic variables on the yield of transient crops in the province in Los Ríos, Ecuador
e objective of this study was to determine the changes and effects of climate variables on transient crop yields in the province of Los Ríos, Ecuador. Temperature and precipitation were analyzed based on historical series from 1981-2015, current series (2016-2019) and projections (2019-2050). Arc...

| description | e objective of this study was to determine the changes and
effects of climate variables on transient crop yields in the province of Los Ríos, Ecuador. Temperature and precipitation were analyzed based on historical
series from 1981-2015, current series (2016-2019) and projections (2019-2050). ArcGis 10,3
soware was used to measure the climatic variability of these parameters. Vulnerability analysis
considered production under the effect of weather conditions. Results indicate that the average
multi-year temperature variation is 25,86 °C and the precipitation is 2 202.83 mm, what favored
the production of 5 225 kg ha -1 of maize, 3 076.8 kg ha -1 rice and 1 147 kg ha -1 of soybeans.
According to climate projections for 2016-2050, an increase of 1.07 ° C in the temperature
variable and decrease in precipitation (303 mm) which will generate a decrease in crop yields in
29; 27 and 24 % for corn, rice and soy respectively. |
