“…Fatichi et al discussed the effects of climate on the policy utility of FCS [30]. In addition, external factors such as the quality of the soil [31] and CO 2 concentrations [32] will also influence this role. However, few studies have empirically analyzed this role from the perspective of the drivers of policy implementation.…”

Rapid urbanization has brought economic dividends to China, but it has been accompanied by inefficient land use. Meanwhile, the mechanism of forestry carbon sinks (FCSs) on land use efficiency (LUE) has not been sufficiently discussed in the context of the pursuit of “carbon neutrality” around the world. Based on the idea of the benefit–cost theory, this study investigated the impact of FCSs on LUE in 30 provincial-level regions (2006–2019) in China using the difference-in-difference model. The results showed that, first, via the mechanisms of public opinion (PO) and rewards and penalties (RP), FCSs could significantly improve the LUE in the regions, and that the former had a greater effect than the latter; second, the tests of the assumption of parallel trends showed that FCSs had a slower effect on the LUE under the PO mechanism than under the RP mechanism; third, the analysis of the LUE showed that the improvement in LUE mainly occurred in the eastern, central, and southwestern regions of China. The conclusions were as follows: (1) FCS is able to promote LUE via both the PO and RP mechanisms; (2) there is a lag in the promotion of LUE by FCS, and the lag is larger with the PO mechanism; and (3) there is spatial clustering in the promotion of LUE by FCS. In line with these conclusions, we propose policy recommendations to better exploit the policy effects of FCSs in three aspects, namely promoting the development of forestry carbon sink projects, improving the relevant mechanisms of FCSs, and improving the mechanisms of PO and RP.

Isiolo dam is planned to be constructed along the Ewaso Nyiro River to provide water to the planned Isiolo resort city, one of the Lamu Port and Southern Ethiopia Transport (LAPSSET) corridor projects. This paper evaluates the factors driving land cover transitions and their effects, as a consequence of the proposed infrastructure developments with a view to providing evidence-based information for formulating policies and approaches for sustainable land management and development. Landsat images were used to assess Land Use and Land Cover (LULC) change, while land degradation was evaluated based on the United Nations Convention to Combat Desertification guidelines (2000–2020). Spatial overlays of land degradation, LULC change, population, and land tenure were performed to establish their interrelations. The results revealed that water, bareland, built-up, and forest increased by 2043%, 83%, 35%, and 17%, respectively, while shrubland and cropland decreased by 26% and 6%, respectively. Further, 61% of the watershed remained stable, 31% experienced degradation and 8% improved. The main drivers of LULC transitions, and land degradation are population pressure, land tenure, climate change and economic growth. With the development of the LAPSSET projects, it is projected that built-up areas, cropland, and bareland will increase mainly due to population increase, while the forest and shrubland will reduce mainly as a consequence of an increase in built-up areas and potentially poor land management. To achieve sustainable development with net zero loss of natural resources, proper planning for economic investments as well as inclusive land-use planning should be enhanced in drylands such as the Isiolo watershed and similar landscapes.

Summary Forests are the most important carbon pools among terrestrial ecosystems, and ensuring less disturbance of sacred groves might constitute a form of forest management for carbon sequestration and climate change reduction. The carbon contents in Zagros oak sacred groves and silvopastoral lands were compared to determine the carbon sequestration potential of these forests. Using a nested sampling design, we measured total carbon content (tC ha–1; aboveground tree biomass, aboveground sapling biomass, belowground biomass, soil organic carbon, leaf litter, herbs and grasses and dead wood and fallen stumps) in both forest groves and silvopastoral lands. The mean total biomass and mean total carbon content varied between sacred groves (453.8 t ha–1 and 338.79 tC ha–1, respectively) and silvopastoral lands (89.4 t ha–1 and 113.46 tC ha–1, respectively). Mean soil organic carbon was significantly lower (71.44 tC ha–1) in silvopastoral lands than in sacred groves (125.49 tC ha–1). The mean total sequestered carbon dioxide (CO2) was 1243.36 tCO2 ha–1 in the sacred groves and 416.40 tCO2 ha–1 in silvopastoral lands. We conclude that human activities have reduced the CO2 absorption capacity of the forests. The substantial disparities between the landscapes emphasize the need to restore damaged forests, and sacred groves might be a useful model for increasing carbon storage in these forests.
