Assessing Forest Vulnerability to Climate Change Combining Remote Sensing and Tree-Ring Data: Issues, Needs and Avenues

چکیده
Forests around the world are facing climate change. Increased drought stress and severe heat waves in recent decades have negatively impacted on forest health, making them more vulnerable prone to dieback mortality phenomena. Although term vulnerability is used indicate an increased susceptibility of forests change with a worsening their vigour status that can compromise ability respond further extreme events, there still uncertainties how evaluate it. Indeed, evaluation complex both because some critical issues estimation methods multiple factors influencing response ongoing A way assess environmental stresses by combining remote sensing dendroecological data. However, these two approaches entail uncertainties, including growth/photosynthetic relationships, carbon allocation dynamics, biases tree-ring data noisy data, which require clarification for proper monitoring pre- post-drought trajectories. Our review aims create overview current literature knowledge understand issues, needs possible solutions research addressing. We focus Mediterranean located warming hotspot showing high aridification.

Combining of Magnitude and Direction of Change Indices to Unsupervised Change Detection in Multitemporal Multispectral Remote Sensing Images
In remote sensing, image-based change detection techniques, analyze two images acquired over the same area at different times t1 and t2 to identify the changes occurred on the Earth's surface. Change detection approaches are mainly categorized as supervised and unsupervised. Generating the change index is a key step for change detection in multi-temporal remote sensing images. Unsupervised chan...

متن کاملChange Detection in Mire Ecosystems: Assessing Changes of Forest Area Using Airborne Remote Sensing Data
The objective of this paper is to present an approach for assessing tree growth and shrub encroachment between 1997 and 2002 in open mire land using CIR-aerial images, DSMs and LiDAR data. The study area is located in the Pre-alpine zone of Central Switzerland. The present study was carried out in the framework of the Swiss Mire Protection Program, where changes of forest area are a key issue. ...
متن کاملAssessing the Impacts of Local Knowledge and Technology on Climate Change Vulnerability in Remote Communities
The introduction of new technologies into small remote communities can alter how individuals acquire knowledge about their surrounding environment. This is especially true when technologies that satisfy basic needs, such as freshwater use, create a distance (i.e., diminishing exposure) between individuals and their environment. However, such distancing can potentially be countered by the transf...
