Food insecurity, deforestation, and forest degradation are significant challenges to achieving the Sustainable Development Goals in sub-Saharan Africa. Slash-and-burn cultivation and conventional logging (timber and charcoal production) are two interrelated activities that lead to forest loss and undermine food security. However, the environmental and economic incentives to clear or conserve the forest have yet to be discovered. To address this gap, our study collected costs and benefits data to assess financial profitability and viability related to forest conversion to slash-and-burn cultivation options (e.g., mono-cropping of maize and intercropping between maize, cassava and pigeon peas) and forestry exploitation (logging and charcoal production) practices in smallholders in Zambézia province, central Mozambique. Conventional logging was the highest cost activity (1662 US$ ha−1) compared to charcoal production (278 US$ ha−1) and cropping systems. Estimated total costs for cropping ranged from 302 US$ ha−1 to 508 US$ ha−1. Cropping systems appear more profitable in the first year of investment (30 to 1495 US$ ha−1) than forestry activities. On the other hand, the estimated profits for logging and charcoal production are negative at 15 US$ ha−1 and 782 US$ ha−1, respectively. Regarding viability, cropping systems showed the highest indicators compared to forestry activities. Based on the financial assessment, cropping systems seem attractive land use options with the fastest and highest financial returns and the lowest production costs. As such, it is not easy to prevent them. The long-term implications of increasing deforestation to the detriment of the cropping system can translate into rapid ecosystem degradation that can worsen livelihoods. |
