Impact of soil and water conservation measuren on catchment hydrological response: a case in north Ethiopia [PDF]

, 2010
Impact studies of catchment management in the developing world rarely include detailed hydrological components. Here, changes in the hydrological response of a 200-ha catchment in north Ethiopia are investigated.

Agricultural Transformation and the Politics of Hydrology in Northern Thailand

Development and Change, 2003
AbstractTensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand,

Multisensor Data Fusion for Automatized Insect Monitoring (KInsecta) [PDF]

Remote Sensing for Agriculture, Ecosystems, and Hydrology XXV, SPIE 12727 (2023) 1272702
Insect populations are declining globally, making systematic monitoring essential for conservation. Most classical methods involve death traps and counter insect conservation. This paper presents a multisensor approach that uses AI-based data fusion for insect classification.
