Organic amendments enhance soil quality in agroecosystems, although they may modify the dynamics of greenhouse gas (GHG) emissions, highlighting complex interactions between soil management and environmental sustainability. A field experiment was conducted in the semiarid region of Iran to evaluate the effects of barley residues (BR), sheep manure (SM), and their combination (BR+SM) on soil carbon dioxide (CO2) and nitrous oxide (N2O) emissions under maize and mungbean. In mungbean, both SM and BR+SM resulted in higher CO2 fluxes than BR. Conversely, in maize, cumulative CO2 emissions were similar among treatments. Under mungbean, BR+SM exhibited higher soil N2O values than SM and BR. The lowest cumulative CO2 (4.77 ± 0.24 and 5.29 ± 0.37 Mg ha−1 year−1 for maize and mungbean, respectively) and N2O (4.73 and 3.00 kg ha−1 year−1 for maize and mungbean, respectively) values were measured in the BR, whereas the BR+SM resulted in significantly high cumulative CO2 and N2O under both crops. Cumulative CO2 fluxes were 21.5% and 53.5% lower in the BR than BR+SM under maize and mungbean, respectively. Similarly cumulative N2O was 48% lower in the BR than in the BR+SM treatment under the mungbean cropping system. Application of BR can be considered as an effective alternative management strategy in terms of lowering GHG emissions under maize and mungbean. By exploring the impact of organic input management on soil carbon and nitrogen dynamics in semiarid cropping systems, our study provides key insights for enhancing agricultural sustainability, while reducing GHG emissions.

This study aimed to investigate the effects of pruning period and intensity on the growth and yield of Rosa roxburghii Tratt, a shrub fruit species with significant economic value, to inform optimized pruning practices for its cultivation and management. The experiment was conducted in a 7 year old R. roxburghii orchard in southwest China. A randomized block design with two factors, pruning period (maturity period, dormancy period, and germination period) and pruning intensity (no pruning, light pruning, moderate pruning, and severe pruning), was employed. Growth indicators such as the number, diameter, and length of new shoots, as well as single fruit weight and yield per tree, were measured to assess the effects of pruning. Data were statistically processed using two-factor analysis of variance and principal component analysis. Both pruning period and intensity significantly affected the number of new shoots, new shoot diameter, new shoot length, single fruit weight, and yield of R. roxburghii trees. Moderate pruning during the dormancy period was most effective in increasing the number and diameter of new shoots, while light pruning during the germination period also showed positive effects. An increase in pruning intensity led to higher single fruit weight across all pruning periods, with no significant effect of the pruning period. There was a significant interaction between pruning intensity and period on yield per tree, with moderate pruning during the dormancy period being the most effective in enhancing yield. Moderate pruning, particularly during the dormancy period, is an effective strategy for improving the growth and yield of R. roxburghii. This approach not only controls tree height and crown width effectively but also significantly promotes yield. The study recommends “moderate pruning during the dormancy period” as the optimal practice for the production and management of R. roxburghii, especially in biogeographically suitable areas.

Learnings from the changing Arctic: economy, society, and sustainability

Journal of land use science : 1 (Taylor & Francis, 2025)
The European Arctic is experiencing rapid industrial expansion, driven by global demographic shifts and the transition to carbon-neutral economies. Traditional livelihoods such as reindeer husbandry, fishing, and hunting increasingly compete with industries like fish farming, mining, forestry, and tourism. This editorial examines the socio-economic and environmental implications of these developments, highlighting conflicts over land use, indigenous rights, and sustainability. This editorial recognises the benefits that the industries bring to the local communities while emphasising the need for genuine participation of local stakeholders and diversified economic strategies. It advocates for post-growth frameworks that balance economic, social, cultural, and ecological well-being while cautioning against unchecked industrial expansion.
