Abstract: Based on the input-output survey of farmers and experts in one of the Jiangsu GEF project areas, the cost-benefit analysis method and greenhouse gases estimation method recommended by IPCC were applied to evaluate and compare the social, economic and ecological benefits of the artificial transplanting (ATR), mechanical transplanting (MTR) and direct seeding (DSR) rice under wheat-rice Double Late mode (late rice harvest and late wheat sowing). Results show that the MTR and DSR rice achieved obvious social benefits. Farming measures resulted in lots of man-made greenhouse gases emissions. The ATR rice and wheat rotation mode could obtain the best economic and ecological benefits. The Double Late mode has a good application prospect, but the key of implementing is timely exploiting the recently increased available agricultural climate resources. The cropping pattern of combining the wheat-rice Double Late mode with the ATR is a better choice to mitigate and adapt to climate change.

Key words: artificial transplanting, mechanical transplanting, direct seeding, wheat-rice rotation , multiple cropping Double Late mode, adaptation, yield, benefit, greenhouse gases emissions
