Irrigation

CO2 emissions can be reduced with effective irrigation by increasing yields and crop residues which can enhance carbon sequestration. (Smith et. al., 2008).

Introduction top

Irrigation is sufficiently common that little description is required. Suffice as to say that all types of irrigation, such as flood, sprinkler, surface and sub-surface drip, can all enhance crop yields with subsequent increases in crop residues and enhanced carbon sequestration. Eighteen per cent of cropped areas are currently irrigated. If additional areas can be put under irrigation, then additional carbon sequestration can occur. Prominent (adaptation) technologies in this area are:

Feasibility of technology and operational necessities top

The adaptation technologies listed above also have positive mitigation effects. For more information about the operational necessities, see the individual technology articles.
