A study has found out that extreme temperatures are becoming more frequent in recent years in Kottayam, Kerala’s major rubber growing area. The production of latex in rubber trees is closely related to the ambient temperature. The productivity of the crop decreases as the temperature goes up beyond a threshold level.
Earlier studies clearly showed that the increase in atmospheric temperature would affectrubber production in India’s traditional rubber growing regions. Thus the impact of changing climate in this region may seriously affect rubber cultivation, if the present warming trend continues.
