Also the soil in RO and RT were tilled more than that used for soyabean during temporary bed preparation resulting in a relatively faster decomposition leaving significantly lower levels of C compared to RS. Change of cropping systems from RR to other annual crops such as RT and RO reduced the soil C sequestration to a significant level after 10 years of cultivation.
A spokeswoman for the EU's Joint Research Centre, which oversees the EDO, said farmers should prepare to adapt to a warmer climate with "diversification or change of crop types and varieties, but also a more efficient use of water".
Scientists have argued over the potential effects of climate change on crops, largely basing their contentions on laboratory tests and computer models of climate and crop yield.
Nonetheless, Santam was preparing for the effect of climate change on crops.
The potential impacts of climate change on crop productivity are of widespread interest to those concerned with addressing climate change and improving global food security.
This is emphasized by the impelling demand of climate resilient varieties because of the predicted impact of climate change on crop productivity together with the impending population demand.
Combining climate change, crop growth and crop disease models to predict impacts of climate change on crop diseases can guide planning of climate change adaptation strategies to ensure future food security.
'Assessment of many studies covering a wide range of regions and crops shows that negative impacts of climate change on crop yields have been more common than positive impacts (high confidence).
Overall, the report said, "Negative impacts of climate change on crop yields have been more common than positive impacts".
