Cumulative impacts of interbasin water transfer and salinity intrusion on water security in central Vietnam.

Saltwater intrusion poses a significant threat to freshwater availability in downstream regions globally, leading to economic losses, compromised water supply, reduced agricultural productivity, social instability, and environmental degradation. This study assesses the extent and drivers of salinity intrusion in the downstream areas of the Vu Gia Thu Bon River basin, central Vietnam, with a particular focus on Da Nang City. The analysis considers the impacts of upstream dam operations and inter-basin water transfers on water supply and irrigation, encompassing both direct and indirect damages.

Machine learning-supported quantification and characterization of sediment plastic debris in an Anthropized Mfoundi River in Cameroon: Implications for the incidence of flood events.

The emergence of plastic pollution as a global threat to both terrestrial and aquatic organisms has seen efforts geared toward minimizing its production and monitoring widespread distribution within the ecosystem. Though with distinct characteristics and sources, plastic debris and sediments often interact in the natural environment through a complex relationship, forming "sediment plastic debris" (SPD) which leaks into the riverine system through human actions or elements of nature. Quantifying SPD in riverine environments is therefore essential for understanding the extent of pollution and its ecological impacts.

Long-term assessment of hydropeaking and cumulative impacts on sediment transport, grain size dynamics, channel stability and water resource management.

Hydropeaking refers to rapid and frequent changes in flow discharge and water levels caused by the operation of hydropower dams. This phenomenon is driven by the need to meet fluctuating electricity demands, with water being released or stored to generate power as needed. High energy demand leads to hydropeaking, significantly impacting water resource management in downstream areas.

An assessment of uncontrolled human interventions on the contemporary sediment budget and morphological alterations of the Vu Gia Thu Bon River basin, central Vietnam.

The Vu Gia Thu Bon (VGTB) River basin is critical for regional development and prosperity in water resources. However, human interventions (e.g.

Quantifying the consequences of unsustainable sand mining and cascade dams on aspects in a tropical river basin.

Human interventions at the river basin scale, such as sand mining and hydropower dam construction, have profoundly affected hydrological and hydraulic alteration regimes, sediment budgets, and morphological changes worldwide. Quantifying the consequences of unsustainable ongoing sand mining and hydropower is crucial for obtaining sediment load data and managing hydrogeomorphology. In this study, comprehensive long-term consecutive four-field monitoring, statistical methods, and hydrological models (SWAT) were applied to quantify the spatiotemporal changes in long-term discharge and sediment load from 1996 to 2020 for the tropical river of the Vu Gia Thu Bon (VGTB) in the central region of Vietnam.

Does tourism reduce the shadow economy? An international evidence.

This paper investigates one of the positive contributions of tourism to the economy through the lens of its influences on the shadow economy. Specifically, our study analyzes the effects of five indicators of tourism consumption (including domestic tourism spending, international travel and tourism consumption, business tourism spending, leisure tourism spending, and outbound tourism spending on the percentage of shadow economy to GDP) in 129 economies between 1996 and 2015. We find interesting results that contribute to the existing literature about tourism economics.

Financial development and energy poverty: global evidence.

This study aims to shed light on the determinants of energy poverty by examining the role of financial development. Notably, the study analyses the multidimensional effects of financial development (including two subsectors and three dimensions on five indicators of energy poverty). Various estimates are applied with a global sample of 65 economies, consisting of 36 low- and lower-middle-income economies and 29 upper-middle-income economies for 2002-2015.
