I think generally, the main problem in adopting clean development mechanisms for developing countries lies to the fear that it would cut or restrain economic development. Which could be from Government, Individuals and corporate bodies. Thus integrating the strategies in developing planning remains a great challenge.
In developing nations, adoption of mitigating strategies for reducing GHGs emission involves the appropriate technologies know how transfer to small and marginal farmers and thereafter effective adoption by the farmers. Say country like India, where numerous agro-ecologies, numerous crops/cropping systems and varuing inputs and management options, it requires a strong platform or decision support system for transfer of appropriate technologies to the farmers, may be it is a slow process of adoption but taking place. Lot of research work in this regard is done already, and already in process of communications to the farming community for their adoption.
As far as adaptation strategies are concerned, farmers have to be communicated for the appropriate methods to deal with the extreme climatic events, deal with the present climate situation which is of course different from two or three decades back, moreover the knowledge content it seems is possible yer to be strengthened for bringing the other bio-physical and socio-economic drivers other than climate change into consideration. There is a need of appropriate decision support tool in this regard. This adaptation procedure is also going on, but slowly in context of developing nations with features of intensive agriculture
