     <mods:abstract>The agricultural frontier of the Brazilian Amazon is one of the fastest growing agricultural regions in the world, and rapid deforestation makes it one of the largest anthropogenic
      sources of greenhouse gas emissions from land-use change. Chapter 1 tracks contemporary (2000 to 2006) changes in land cover and land use with a new remote sensing methodology, applied to the
      entire state of Mato Grosso, a hot spot for Amazon agricultural development. A bookkeeping model is applied to estimate the impacts of land-cover and land-use change on the regional carbon
      budget. In Chapter 2, the land-use data set is expanded to cover historical changes in land use (1901-2006), as reconstructed here with government census and survey data disaggregated in a
      spatial reconstruction. The impacts of 105 years of land-use change are evaluated using a process-based ecosystems model (Terrestrial Ecosystems Model, TEM). There is a land-use legacy effect
      not included in previous land-use modeling efforts for this region. Additionally, the long-term historic modeling effort allows identifies the CO2 fertilization effect on intact vegetation that
      shorter-term studies have dismissed despite recent field studies documenting this effect in the Amazon. Chapter 3 combines deforestation scenarios (Business-As-Usual and Governance) with
      different land uses (Pasture and Crop) in TEM to estimate the range of future greenhouse gas emissions, including carbon dioxide, methane and nitrous oxide. The results from this chapter show
      that nitrous oxide emissions from croplands will become an increasing source of greenhouse gas emissions under all scenarios and weighs the trade-offs for agricultural development and potential
      conservation in terms of carbon emissions or uptake.</mods:abstract>
