Agroforestry plantations and urban habitats contribute importantly to atmospheric volatile compound fluxes in densely populated areas. Simulation of emissions from such habitats is associated with several key challenges, including high spatial heterogeneity due to habitat fragmentation and high diversity of planted tree species. On the other hand, plants in urban habitats and in agroforestry plantations commonly receive more nutrients and water than species in natural communities, resulting in higher production and potentially greater capacity for volatile production per unit of land area. This chapter reviews the strategies for simulation of biogenic volatile organic compound (BVOC) fluxes from urban habitats and agroforestry plantations and provides an outline for parameterization of volatile emission models for densely populated areas with high vegetation fragmentation and large number of gardened, often exotic, tree species.
