Economic Analysis of Infrastructure Investment and Break‐Even Carbon Prices for Low‐Water, Low‐Emission Farming Techniques in Vietnam

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Excessive water use in rice production is a major source of methane emissions, the dominant greenhouse gas from Vietnam's agricultural sector. Improving water‐use efficiency can enhance water security and reduce emissions, but achieving these gains requires substantial changes in farming practices and significant investment in supporting ...

STRATIFIED ADAPTATION: Infrastructure, Elevation, and Cascading Floods in the Urban Mekong Delta

International Journal of Urban and Regional Research, EarlyView.
Abstract Flood‐prone cities in the global South are increasingly the target of infrastructure projects aimed at building climate ‘resilience’. At the same time, residents of these cities take adaptation to flooding into their own hands. In this article we examine the interrelationship between household‐scale and urban‐scale flood mitigation projects in

Optimization of Sluice Gate under Fatigue Life Subjected for Forced Vibration by Fluid Flow

Journal of Mechanical Engineering, 2018
A ‘Sluice’ is a water-flow control gate works with sliding. So, it’s a mill race, flume or a penstock, channelling water towards a water mill, traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway.

Spatio‐Temporal Dynamics of Asian Clams in Two Mediterranean Canals

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The rapid spread of the non‐native invasive Asian clam (Corbicula spp.) has been linked to the catastrophic decline of native freshwater mussel assemblages in Europe and North and South America. This study evaluates the spatio‐temporal dynamics and shell size structure of the Asian clam within two Mediterranean canals: Canal Imperial de Aragón

What Drives the Changing Characteristics of Plankton in Floodplain Lakes: Season, Environmental Factors, or Lake Characteristics?

Ecology and Evolution, Volume 16, Issue 9, September 2026.
In this study, we conducted investigations and monitoring on lakes during the wet season and dry season. We studied the structure, taxonomic/functional diversity, community assembly, and niche differentiation of plankton communities, analyzed the biogeographical patterns of plankton communities, and explored the driving factors affecting plankton ...

The Usage History of the Aqueduct of Nîmes Reconstructed From Carbonate Archives: Operation, Modifications and Late Antique Breakdown and Change

Geoarchaeology, Volume 41, Issue 5, September/October 2026.
ABSTRACT Anthropogenic carbonate deposits in Roman aqueducts can provide detailed environmental and archaeological information. The Roman aqueduct of Nîmes (France), famed for the Pont du Gard bridge, was built around AD 50 to convey water over 50 km to the city of Nemausus for drinking and bathing.
