Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE
Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 3-38, March 2025.Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

Effect of river cleaning on lowland drainage in South‐Eastern Sumatra
Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.Abstract We study a tropical river in South‐East Sumatra, where land drainage in the coastal zone has resulted in subsidence and increased flooding risks, exacerbated by sea tides. The novelty of this research is in determining the effect of tide on the lowland drainage system for forestry in a coastal tropical region and the impact of river cleaning ...

Towards liminal balance: Unpacking the UK's urban canal space
Transactions of the Institute of British Geographers, Volume 50, Issue 1, March 2025.Short Abstract This paper explores the liminal geographies of the UK's canal network. It highlights critical intersections between liminality and scale and examines ongoing spatial entanglements. The findings underscore the importance of preserving urban canals as liminal spaces, promoting recreation and urban wellbeing, and advocate for maintaining a ...

Robust Path Following on Rivers Using Bootstrapped Reinforcement Learning [PDF]
arXiv, 2023 This paper develops a Deep Reinforcement Learning (DRL)-agent for navigation and control of autonomous surface vessels (ASV) on inland waterways. Spatial restrictions due to waterway geometry and the resulting challenges, such as high flow velocities or shallow banks, require controlled and precise movement of the ASV. A state-of-the-art bootstrapped Q-

Locked out? Navigating the geographies of precarity on Britain's waterways
Transactions of the Institute of British Geographers, Volume 50, Issue 1, March 2025.Short Abstract Our qualitative investigation reveals a diversity of practices and experiences of marginalisation on British waterways, drawing out the impacts of temporal and spatial fluidity to inform our understanding of precarity in a mobile world. The mobility and liminality offered by boat living, experienced by some as a chosen freedom and others

Wild Bee Assemblages and Pollination Networks of Managed Emergent Wetlands in Central New York, USA
Ecology and Evolution, Volume 15, Issue 2, February 2025.Wetlands are underrepresented in wild bee surveys yet we find they host a diversity of bee species and offer important late‐season floral resources. Wetland restoration and management for wildlife in the northeastern United States creates a matrix of freshwater wetland habitat that helps support the landscape's wild bee fauna.

Roman Navigation in Venice Lagoon: the Results of Underwater Research
, 2010 Venice lagoon formed part of a network of inland waterways used for navigation in the northern Adriatic, an almost continuous system of lakes, river‐mouths and canals, at least partly pre‐Roman in origin. The fossae which cross the present lagoon are the

Aspects of Ammonia as Green Fuel for Propulsion Systems of Inland Water Vessels
Energy Technology, Volume 13, Issue 2, February 2025.Within the CAMPFIRE project, an ammonia‐powered propulsion concept is being developed for use in inland water vessels. The core of the system is an ammonia‐fueled high‐speed engine that drives a generator. A cracker splits some of the ammonia into hydrogen and nitrogen to ensure better ignition and efficient combustion.

Evaluating and elevating the role of wildlife road crossings in climate adaptation
Frontiers in Ecology and the Environment, Volume 23, Issue 1, February 2025.Beyond the well‐established benefits of wildlife road crossings and associated infrastructure—improving driver safety, reducing animal mortality, reconnecting habitats—there is another important but often underappreciated benefit: supporting wildlife and ecosystems in adapting to climate change.
