Summary: Research evaluated LULCC datasets for Brazil, showing that the global HYDE 3.3 dataset is an improvement in representing LULCC but estimates lower magnitudes compared to MapBiomas. Both JULES-ES and BLUE models simulate a slowdown in emissions after 2004, in line with other global models and official reports.

Summary: This study investigates the impact of deforestation on bat host species richness and diversity, as well as viral prevalence and richness in different forested and deforested sites in the interior Atlantic Forest of southern Brazil. The results suggest that deforested sites have lower bat diversity but higher viral prevalence and richness compared to forested sites, with viral detection more likely in juvenile males in deforested sites.

Summary: This paper investigates the effects of advancing deforestation in the southwestern Amazon on local hydroclimate. The results show that land-use changes such as deforestation reduce evapotranspiration and net radiation at the surface, and increase sensible heat flux during the dry season. During the rainy season, deforestation intensification leads to increased evapotranspiration and modifies the other components of energy balance. Land-use changes also reduce streamflow during the dry season and increase streamflow during periods with normal precipitation conditions and La Nina events in most sub-basins, except in highly deforested areas.

Summary: In this study, the impacts of land use and climate changes on river flows in the Cerrado biome, Brazil, were assessed using field and secondary data from 1985 to 2018. Future deforestation and climate scenarios up to 2050 were projected, and their impacts on surface water were predicted. The study found that large-scale deforestation for irrigated agricultural production had a more significant impact on river flows than climate changes. It was estimated that deforestation and climate changes led to a decrease of 8.7% and 6.7% in streamflow, respectively. The combined effects of land use and land cover changes and climate changes resulted in a total reduction of -19,718 m(3)/s in surface water within the Cerrado watersheds. By assuming current deforestation rates, it was predicted that there would be a total water reduction of 23,653 m(3)/s by 2050, equivalent to a decrease of 33.9% in river flows in the region.

Summary: The expansion of agricultural activities in the Brazilian Cerrado has led to loss of native vegetation, decline in biodiversity, and increased greenhouse gas emissions. The study focuses on the spatiotemporal behavior of vegetation and agricultural areas in the Cerrado - MATOPIBA region, showing significant expansion of soybean planted areas and productivity. The findings highlight the need to reinforce the preservation of Cerrado native vegetation areas and address deficits in conservation policies.

Summary: The objective of this study was to evaluate the effects of land use, temperature, and nitrogen on N2O emissions in soils in the Amazon. The results showed that land use and temperature had significant impacts on N2O emissions, with the highest emissions observed in agricultural soils. However, N2O emissions in the soil of the Amazon rainforest were low regardless of temperature and nitrogen treatments.

Summary: Land use, temperature, and nitrogen application have significant impacts on CH4 emissions from soils in the Amazon region. Pasture soils have the highest emissions, while forest and agricultural soils are affected by CH4 oxidation. Temperature and nitrogen fertilization both affect CH4 emissions, with higher temperatures and nitrogen input leading to increased concentrations of CH4 emissions.

Summary: Deforestation of the Amazon rainforest poses a threat to global climate and biodiversity. Understanding the drivers of deforestation processes, such as spillover effects and varying impacts over time and space, is crucial for effective policy design. Neglecting the spatial dimension and assuming homogeneous impacts can lead to distorted inference, highlighting the importance of considering complex and dynamic processes behind deforestation.

Summary: This study investigates the hydrological effects of deforestation in the Upper Chao Phraya River basin, a tropical monsoon region in Thailand. The findings suggest that deforestation contributes to increased annual streamflow, baseflow, and sediment load. The impact of deforestation varies depending on the specific sub-basin and the type of hydrological change. Climate change and forest cover reduction both play a role in affecting the hydrological and sedimentary changes observed in the region.

Summary: The study investigated trends and drivers of intermittency signatures of non-perennial streams across the United States, revealing that half of the gages showed significant trends in at least one signature during a specific time period, with changes in no-flow duration being the most common. Regional patterns of change showed widespread drying in the southern US and wetting in the north.

Summary: Climate change is a significant factor affecting water supply in semi-arid and arid areas such as Iran. This research investigates the impact of climate change and upstream land use on the Tajan River in northern Iran. The study shows that peak streamflow will increase by 4% and 5.7%, while average annual discharges will decrease by 16% and 16.5% from 2016 to 2066 under different climate scenarios. Furthermore, different land use change scenarios lead to an increase in average annual streamflow by 8.5-15.8%. It is concluded that downstream water users should implement strategies to cope with the changing climate and water scarcity.

Summary: This study examined the variation in streamflow components and their relationships with watershed properties in different regions of Kansas, USA. The results showed that both baseflow and surface runoff increase with precipitation, but the increase in surface runoff is greater. The baseflow index decreases with increasing precipitation, indicating the limitations of infiltration on recharge/runoff partitioning. The spatial patterns of variables influencing infiltration, such as land use and soil texture, also vary with precipitation.

Summary: This study analyzes the impacts of two cocoa production systems, full-sun and agroforestry, at the farm-level and beyond the farm-level. The findings show that cocoa agroforestry performs worse at the farm-level, but brings the largest gains in carbon and biodiversity at the landscape level. Sustainable land management and sustainable intensification can mitigate the negative impacts of increasing cocoa demand on carbon stocks and biodiversity.

Summary: Soil bulk density (rho(b)) is an important indicator of soil quality and productivity. This study evaluates the performance of recalibrating existing Pedotransfer functions (PTFs) for rho(b) estimation using new observations. The results show that recalibration of PTFs reduces errors and provides comparable or better performance than developing new PTFs. This provides a viable alternative for estimating rho(b) in data-scarce regions.

Summary: In drylands, runoff redistribution during storms from bare soil areas to vegetated patches is important for vegetation growth. The interaction of surface roughness and permeability determines the extent of this redistribution. Virtual experiments and the use of the 2D Saint Venant Equations were employed to measure runoff connectivity and identify landscapes likely to shed water.

Summary: Observations show variable vulnerability segmentation between stems and leaves within and between environments. A hydraulic model was developed to test hypotheses about vulnerability segmentation and its interaction with other plant traits. Results suggest that conventional vulnerability segmentation helps preserve conductance in stems, while reverse vulnerability segmentation is more effective in maintaining conductance across the stem-leaf hydraulic pathway. Further study is needed to understand the impact of vulnerability segmentation on transpiration rates and recovery from water stress.

Summary: On dryland hillslopes, vegetation water availability is subsidized through the redistribution of rainfall runoff from bare soil to vegetation patches. The connectivity within bare soil areas plays a crucial role in the establishment and persistence of dryland ecosystems. Inferring functional connectivity from structural landscape features is an attractive approach, but the relationship between the two remains uncertain and requires further exploration.
