FALLOW is a landscape-dynamics model, which comprises the following main annual dynamic processes: (1) plot-level soil fertility dynamics in crop and fallow phases affecting agricultural crop production; (2) food storage, use and sale at the village level, with options along the spectrum from ‘full dependence on local food production' to ‘fully market integrated' economy; (3) farmer decisions on increase or decrease of the area cropped, depending on labour availability and expected profitability of various land use options, as they have learnt from past experiences within the simulation; (4) spatial implementation of choices for clearing land, choosing among the options available; and (5) impact assessment of how the resultant mosaic of land cover types and successional processes will affect watershed functions (annual water yield, base flow, net sediment loss), biodiversity indicators and carbon stocks.
