Improved crop and grazing land management to increase soil carbon storage; restoration of cultivated peaty soils and degraded lands; improved rice cultivation techniques and livestock and manure management to reduce CH 4 emissions; improved nitrogen fertilizer application techniques to reduce N 2 O emissions; dedicated energy crops to replace fossil fuel use; improved energy efficiency. AR4 WG3 chapter details: The now-published text gives a warning that the new estimation of sea-level could be too low: More efficient end-use electrical equipment; heat and power recovery ; material recycling and substitution; control of non-CO 2 gas emissions; and a wide array of process-specific technologies.
