Transition pathways from vulnerability to viability of small‐scale fisheries in Africa and Asia

People and Nature, Volume 8, Issue 5, Page 1033-1049, May 2026.
Abstract This perspective paper examines transition pathways that move small‐scale fisheries from vulnerability towards viability. We understand ‘vulnerability to viability transition pathways’ as integrative and one that extends beyond economic concerns to include social, political, cultural and ecological aspects of small‐scale fisheries.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

The use of kinematic photogrammetry and LiDAR for reconstruction of a unique object with extreme topography: a case study of Dutchman’s Cap, Baltic seacoast, Lithuania

Frontiers in Remote Sensing
Nowadays, the development of Unmanned Aerial Vehicle in conjunction with Photogrammetry and LiDAR technologies, has revolutionized the collection of geospatial data. These technologies enable the acquisition of very high-resolution images and dense point

Digital Airborne Photogrammetry—A New Tool for Quantitative Remote Sensing?—A State-of-the-Art Review On Radiometric Aspects of Digital Photogrammetric Images

Remote Sensing, 2009
The transition from film imaging to digital imaging in photogrammetric data capture is opening interesting possibilities for photogrammetric processes. A great advantage of digital sensors is their radiometric potential.

Assessing functional diversity and composition using multispectral images in Atlantic Forest restoration sites

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction By focusing on the specific functional traits of species, we can better understand how ecosystems function and respond to environmental change. However, field measurements of functional traits can be time‐consuming and costly, whereas remote sensing data can serve as viable alternatives for studying biodiversity at larger scales ...

Irrigated Acreage in Georgia's Altamaha River Basin During the Drought Year 2000 [PDF]

, 2005
Using a "mixed media" approach, which tracts changes in pixel (color) values over the summer indicating changes from dry land to wet land, we have developed estimates for irrigated acreage in the Altamaha River Basin that draws water from ground water or
