Summary: A rights-based approach to adaptive social protection is a promising policy measure to address vulnerability to climate change, yet it struggles to gain support compared to production and growth-oriented interventions. Using Ethiopia's Productive Safety Net Programme as a case study, this research shows how climate discourses hinder progress towards socially transformative outcomes. The intertwining narratives of moral leadership and green growth shape the PSNP's climate-smart approach, but are embedded within politics that prioritize modernization and growth-oriented policies. These narratives rationalize a strong central State and its control over natural resources, which in turn condition the PSNP to favor technocratic, productivist approaches that reproduce vulnerability instead of challenging it.

Summary: This study analyzed local perceptions on climate change, examined its impact on local livelihoods and food security, and explored adaptive responses and challenges by using the Dormaa West District in Ghana as a case study. The results showed evidence of climate change with unpredictable precipitation and warming temperatures. Key adaptive responses included reliance on remittances and adjusting growing and harvesting seasons, however, these measures were found to be ad hoc and unsustainable. Incorporating farmer-based adaptation strategies and stakeholder participation are imperative in finding effective and sustainable adaptive response measures.

Summary: Human development aims to increase freedom by building capacity, which is crucial for achieving sustainable development in the Anthropocene era. However, the efficiency and effectiveness of capacity building are limited. The first and second generation adaptive capacity models fail to address the issues of scale and the interaction between individuals and groups in enhancing or diminishing capacity. To achieve climate-resilient development, a next (third) generation of adaptive capacity that incorporates capacity transfer is necessary.

Summary: The study in the desert steppe of Inner Mongolia, China, found that finer soil particles generally had higher SOC contents, leading to a proposed method to calculate SOC content in aeolian sediment. The calculated results were highly consistent with the measured results, providing a more precise estimation of SOC loss induced by wind erosion. Simulated results showed SOC loss induced by dust emissions ranging from 0 to 39 g/m(2)/y during the period of 2001 to 2017, which could be valuable for carbon budget estimation in the desert steppe.

Summary: Observed atmospheric dust in North America has displayed significant variability over the past two decades, which correlates with changes in regional vegetation and wind speed patterns. Dust emission models have the potential to explain the relationship between these direct causes and changing dust emission. However, existing models that assume homogeneous land cover types and fixed vegetation classes over time do not adequately represent the changing aerodynamic roughness of different types of vegetation. To overcome these limitations, a new MODIS albedo-based dust emission model calibrated to satellite-observed dust emission point source data was used to explain changing dust emission from 2001 to 2020. By focusing on four regions in the southwestern USA, identified as the main dust emission sources, the study classified the controlling factors of wind speed and aerodynamic roughness that contribute to dust emission change. Results from the calibrated model show that dust emission is increasing or decreasing in different regions, at different times, and for different reasons, suggesting the absence of a secular change in observed atmospheric dust. This research highlights the potential of using a calibrated dust emission model that accounts for changing vegetation structure, configuration, and wind speeds to gain new insights into the factors controlling dust emission. Additionally, this approach shows promise for modeling historical and future dust emission responses using prognostic albedo in Earth System Modeling.

Summary: Accurate representation of surface roughness is important for predictive models of aeolian sediment transport and dust emission. However, the variability of surface shear velocity and shear stress ratio is poorly described. This study examines the spatiotemporal variability of shear stress ratio before, during, and after vegetation green-up in a shrub-invaded grassland. Results show that vegetation green-up leads to reduced soil surface shear velocity and shear stress ratio, and this should be considered in drag partition schemes to accurately predict seasonal aeolian sediment fluxes. Understanding the effects of vegetation phenological phases on drag partition can also provide insights for managing wind erosion.

Summary: The concept of vulnerability has evolved to include the management of social-ecological systems, with a 12-step framework presented to help practitioners minimize exposure, reduce sensitivity, and enhance adaptive capacity. Future directions include applying biocultural approaches, building knowledge about nonclimate stressors, and anticipating potential trade-offs and maladaptation to address sustainability challenges. The framework provides a roadmap for developing integrated vulnerability assessments that are robust, context-specific, and relevant to the management of SES.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
