This study assesses greenhouse gas emission (GHG) reductions and sustainable development impacts connected to the nationally appropriate mitigation action (NAMA) on sustainable charcoal production in Mozambique. The analysis covers the results of the ex-ante assessment of the NAMA potential contribution to the achievement of Mozambique’s Nationally Determined Contribution (NDC) target. The expected impacts show that the proposed actions tied to NAMA (e.g., introducing improved kilns, sustainable forest management, briquetting of charcoal waste and torrefaction) can cumulatively lead to emission reductions amounting to 314,521 ± 45,138 t CO₂-eq (119% reduction) by 2025, and 442,706 ± 26,766 t CO₂-eq (113% reduction) by 2030 at the national level, compared to a business as usual scenario. This shifting represents a transformation of the charcoal sector from a net source of emissions to net carbon sequestrating. The analysis also identifies a wide range of sustainable development cobenefits, including increased income, improved gender equity, job creation (23% increase by 2025, and 15% decrease by 2030), and increased revenue (USD 825,000 by 2025, and USD 1.6 million by 2030). The assessment process concluded that unless robust data collection, processing, and sharing is put in place, a full assessment of all direct and indirect environmental, social, and economic impacts cannot be comprehensively reported. Finally, we highlight the lessons learned and specific barriers for a robust monitoring, reporting, and verification (MRV) of the given policy under the current MRV set up and available capacities.

This study assessed the structure and composition of a Miombo woodland stand subjected to selective logging through a forest inventory, measuring all trees with DBH ≥ 10 cm across 34 plots (1 ha each) for diameter, height, stem quality, and health status. The stand had a mean stem density of 255 stems/ha, basal area of 15 m²/ha, above ground biomass of 110 Mg/ha, and total volume of 145 m³/ha. The Fabaceae family, particularly Brachystegia spiciformis, dominated the composition. Diversity indices revealed moderate diversity (Shannon = 2.3, Simpson = 0.8, Pielou = 0.6), with a few dominant species. The diameter distribution followed a reverse J-shaped pattern typical of Miombo woodlands. The study (LevasFlor. (2024). Plano De Maneio Da LevasFlor, LDA) highlighted common features of selectively logged woodlands, including a low occurrence of large-diameter individuals from high-value commercial species, prevalence of disturbance-tolerant species, and limited regeneration for some species. These findings underscore the need for management strategies that balance ecological and socio-economic factors, mitigate logging impacts, promote regeneration, and ensure long-term sustainability. Effective policies are crucial for maintaining the ecological integrity and economic value of Miombo woodlands while addressing climate resilience and biodiversity conservation.

The Miombo woodlands are declining in both area and value, primarily due to over-harvesting of commonly preferred species. These forests, however, still contain several other species that are potentially of commercial importance. This study aimed to address the need for improved volume and biomass estimates for the sustainable management and utilization of two of the most abundant timber species in Mozambique’s Miombo woodlands: Brachystegia spiciformis (common name: Messassa) and Julbernardia globiflora (common name: red Messassa). Non-linear models were developed to estimate the merchantable wood volume under bark, heartwood volume, and biomass. The volume and biomass models for wood and heartwood volume, which included both diameter at breast height (DBH) and tree height as predictor variables, outperformed single-predictor models. However, the performance of some ratio models using DBH as the only predictor variable surpassed that of models using two predictor variables. The developed models are recommended for adoption by forest companies to increase economic and environmental benefits as they can refine harvest planning by improving the selection of trees for harvesting. Proper tree selection enhances the rate of recovery of high-quality timber from heartwood while observing sustainable forest management practices in Miombo and increasing the proportion of carbon removed from forests, which is subsequently stored in wood products outside the forest.
