Modelling for Estimation and Projection of Carbon Stocks in Land-Use Systems
Models are simplified versions of a system used to estimate and project certain features or functions or outputs of a system. In order to study a system scientifically a set of assumptions about how it works is often made. These assumptions, which usually take the form of mathematical or logical relationships, constitute a model (Law and Kelton 2000). Models are used to make projections of carbon stocks in forests, plantations, grasslands and cropping systems. Models are used to make separate projections for biomass and soil carbon stocks in different pools. Further, models are also available to project above-ground and below-ground biomass separately. Models are often based on several assumptions about data and quantitative relationship between input variables and output values. Thus, model outputs are often characterized by uncertainty due to assumptions made about the relationships between variables.
