There is widespread use of poplar in pulp and paper, match splints, pencil and plywood industries, in northern India. The practice of closer spacing geometry with compact block in poplar cultivation does not permit intercropping from the third year onwards, which discourages small landholders.

Studies on measuring CO2, CH4 and N2O fluxes from five agroforestry systems viz., teak, jatropha, pongamia, simaruba and leucaena were conducted in semi-arid alfisols. This study gives an idea of successive potential values of GHGs in agroforestry systems to compare with carbon sequesteration abilities of these systems.
