Gabriel I ; Nereu A. Streck II ; Lilian O. The objective of this review is to ensemble information from the literature on the response of cassava to climate change. The growth rate of the most plants increases at elevated CO 2 because it is the substrate for photosynthesis, however, the increase in temperature may offset the benefits of CO 2 on crop productivity due to a shortening of the cycle and increase in respiration of maintenance. Results from greenhouse, field and numerical experiments indicate that the response of cassava crop to elevated CO 2 is Consequencias efeito estufa yahoo dating, i.
The increase in temperature projected in future climate scenarios in general should not decrease root yield of cassava, mainly in Africa, where this crop has an important role on food security. Further studies should be made using the current knowledge in order to confirm previous studies on the Consequencias efeito estufa yahoo dating of cassava to elevated CO 2 and temperature in regions where few studies have been conducted, like in Brazil.
