Disentangling the effects of climate and people on Sahel vegetation dynamics [PDF]

Biogeosciences, 2009
The Sahel belt of Africa has been the focus of intensive scientific research since the 1960s, spurred on by the chronic vulnerability of its population to recurring drought and the threat of long-term land degradation. But satellite sensors have recently

Automatic Annotation of Hyperspectral Images and Spectral Signal Classification of People and Vehicles in Areas of Dense Vegetation with Deep Learning

Remote Sensing, 2020
Despite recent advances in image and video processing, the detection of people or cars in areas of dense vegetation is still challenging due to landscape, illumination changes and strong occlusion. In this paper, we address this problem with the use of a

Applying social-ecological system resilience principles to the context of woody vegetation management in smallholder farming landscapes of the Global South

Ecosystems and People
Woody vegetation diversity is declining due to human-induced land-use changes, mainly agricultural expansion and intensification, deforestation, forest degradation and urbanisation.

Monitoring vegetation degradation using remote sensing and machine learning over India – a multi-sensor, multi-temporal and multi-scale approach

Frontiers in Forests and Global Change
Vegetation cover degradation is often a complex phenomenon, exhibiting strong correlation with climatic variation and anthropogenic actions. Conservation of biodiversity is important because millions of people are directly and indirectly dependent on ...

What is the role of trees and remnant vegetation in attracting people to urban parks?

Landscape Ecology, 2014
Public parks commonly contain important habitat for urban biodiversity, and they also provide recreation opportunities for urban residents. However, the extent to which dual outcomes for recreation and conservation can be achieved in the same spaces ...
