Summary: The hydrological processes in watersheds can be greatly affected by changes in climate and Land Use/Land Cover (LULC), leading to significant alterations in precipitation patterns, evaporation rates, and stream flow. This study investigates the future climatic conditions and LULC changes in the Minab River Basin, Iran, and their impacts on streamflow and evapotranspiration. The results show that future changes in climate and LULC will lead to increased evapotranspiration, with potential increases attributable to climate changes and LULC changes. Additionally, changes in LULC are expected to cause a decline in streamflow, although the impact of climate on streamflow varies across different climate scenarios.

Summary: Land use change is a critical factor affecting hydrological processes, and understanding its long-term dynamics is essential for sustainable water resources management. This study aimed to quantify and analyze land use change and its impacts on hydrology in the Sejnane watershed in northern Tunisia from 1985 to 2021. Remote sensing and a SWAT model were used, and land use maps were developed for different years. The results showed significant changes in land use, which strongly influenced water balance components, with an increase in runoff and a decrease in percolation. The construction of a dam, expansion of irrigated areas, and growth of olive tree plantations were identified as major contributors to the hydrological changes.

Summary: The aim of this study is to evaluate the distribution of hydrological responses towards water balance components for a watershed. The study focused on the water balance in the Mahanadi river basin of India, analyzing the impact of Landuse Land Cover (LULC) on runoff using the SWAT model. The results showed that significant increases in runoff and decreases in groundwater contribution were observed from 1994 to 2014 due to changes in LULC.

Summary: A hydrological simulation study in the Xiaoxingkai Lake Basin, China, reveals that climate change has a greater impact on streamflow than land use/land cover changes. The volume of Lake Xiaoxingkai slightly increased during 1961-2017, with climate change contributing the most, followed by direct human activities and land use/land cover changes having a negative effect.

Summary: Central Europe experienced several severe droughts and heatwaves between 2018 and 2020, leading to significant impacts on forest ecosystems. In Germany, bark beetle infestations compounded the damage, resulting in extensive forest loss. This study utilized dense time-series data from Sentinel-2 and Landsat-8 to assess canopy cover loss in Germany from January 2018 to April 2021. The results revealed a total loss of 501,000 hectares, with varying levels of impact across different regions.

Summary: To ensure sustainable wetlands use and prevent wetland degradation, decision-makers and managing institutions require quantitative and spatially explicit information on the condition of wetland ecosystems. Remote sensing, particularly the Wetland Use Intensity (WUI) indicator based on Mean Absolute Spectral Dynamics (MASD), has the potential to assist in wetland mapping, inventorying, and monitoring. Using the Google Earth Engine (GEE), an automated approach for calculating WUI was developed, providing high quality results and requiring minimal user input. The application of WUI in Rwanda demonstrated its potential to assess wetland health and contribute to wetland management efforts, as it is informative, distinct from existing indicators, and applicable even under cloudy conditions.

Summary: This study uses subseasonal to seasonal (S2S) ensemble hindcasts from the ECMWF to evaluate the predictability of rainy season onset dates (RSODs) in different climatic subregions of Vietnam. The results show that the ECMWF model reproduces the observed interannual variability of RSODs well, with better performance at shorter lead times. The choice of RSOD criteria significantly influences the model's skill in predicting the onset dates.

Summary: This study investigates the impacts of climate and land use/land cover change on water resources in an inland valley catchment in Burkina Faso. The results show a large uncertainty in future runoff changes due to climate change, and land use change exacerbates the increase in total runoff. This study highlights the importance of considering land use change in assessing the impact of climate change.
