Water management can be improved along with weather monitoring. Alternative approaches can be implemented for combating pests and tilling the soil. The IPCC notes that such adaptive measures are subject to resource limitations, favoring those with better access to capital, technology, and natural resources. And it concludes that many existing government policies may reduce the farm sector s adaptive capacity. Emissions As the agricultural sector struggles to adapt to climate change, it is likely to experience increasing public pressure to soften its environmental impacts and assist in efforts to curtail overall emissions of greenhouse gases.
Land use constitutes agriculture s most important contribution to emissions.
Where crops are grown, the choice of plants and the manner in which they are cultivated affects the fluxes of carbon to and from the soil. Most of these land-use changes result partially from agricultural expansion. A wide range of measures can limit carbon emissions from agricultural activities. Some can even serve to augment carbon sequestration or offset fossil fuel use by producing biomass fuels. The company negotiated a deal in which a group of Canadian energy companies will pay hundreds of US farmers to implement various measures limiting emissions and increasing carbon storage in soils.
