Asymmetric effect of environmental cost of forest rents in the Guinean forest-savanna mosaic: The Nigerian experience.

Several studies have identified deforestation as a major cause of environmental degradation, but little is known about the asymmetric effect of the environmental cost of forest rents. To fill this gap, our study uses the nonlinear autoregressive distributed lag (NARDL) model and asymmetric causality test to examine the environmental implication of forest rents in the Guinean Forest-Savanna Mosaic of Nigeria over the period 1990:Q1 to 2016:Q4. The empirical results show that forest rents increase CO emissions when the shock to forest rents is positive and decreases CO emissions when the shock to forest rents is negative.
