Monitoring and Reducing Greenhouse Gas Emissions from Agricultural, Forestry and Other Human Activi in guiding key decision makers and policy analysts. We conclude that management strategies that reduce greenhouse gas emissions from agriculture and forestry are likely to be strategies that will also contribute to ecologically sustainable development.

Greenhouse Gas Emissions from Intensive Livestock Systems: Their Estimation and Technologies for Re model intensive dairy farm based on temperate grassland. It is estimated that a typical 76 ha dairy farm in SW England could emit nearly 12 tonnes (t) CH.-C and over 1 t N.O-N. Gaps in existing knowledge are identified and options to reduce emissions discussed.

Monitoring and Reducing Greenhouse Gas Emissions from Agricultural, Forestry and Other Human Activiemissions from agricultural, forestry and other systems requires that the major inputs, components and outputs of the production system are defined. Fluxes of greenhouse gases in natural systems may be estimated by mathematical modelling of the major biological processes and activities. Field and la

This will increase methane emissions from rice-fields if current technologies are kept. Methane emissions from rice

Global Change Strategy Options in the Extensive Agriculture Regions of the World,burning in the more humid regions of the tropics, and methane from cattle production. In terms of direct feedback influence on climate their effects are via opaqueness of the atmosphere (dust and aerosols) and the albedo of the surface. Change in these regions is brought about by the separate and (e
