Student-produced podcasts as an assessment tool: an example from Geomorphology [PDF]
The emergence of user-friendly technologies has made podcasting an accessible learning tool in undergraduate teaching. In a geomorphology course, student-produced podcasts were used as part of the assessment in 2008-2010. Student groups constructed radio

Mega-geomorphology and neotectonics [PDF]
For several decades, subtle neotectonic effects involving several square kilometers have been studied in detail using remote sensing, primarily various types of stereo-aerial photographs at scales of 1:10,000 to 1:80,000. These subtle effects, especially

Determination of Land Degradation in Romania at a Local Scale Using Advanced Analytical Techniques
ABSTRACT Land degradation (LD) threatens the food security and general welfare of many people globally. Land Degradation Neutrality (LDN) is a pivotal goal within the global sustainability agenda, particularly under Sustainable Development Goal (SDG) 15.3.1, which measures the proportion of land that is degraded over total land area.

ABSTRACT Seasonal rest grazing is key to the recovery and sustainable use of alpine grasslands in northern Xizang. Postgrazing changes in soil structure and organic carbon stability are indicative of grassland recovery. However, the mechanisms by which seasonal rest grazing affects these soil properties remain unclear.

Effects of drainage ditches and stone bunds on topographical thresholds for gully head development in North Ethiopia [PDF]
Gully erosion is an extreme process of land degradation operating in different regions of the world. A common way to quantify the susceptibility of land to gully incision is the use of topographical thresholds for different land use types.
