How Universal Is the Relationship between Remotely Sensed Vegetation Indices and Crop Leaf Area Index? A Global Assessment
2016
This study aims to assess the relationship between Leaf Area Index (LAI) and remotely sensed Vegetation Indices (VIs) for major crops, based on a globally explicit dataset of in situ LAI measurements over a significant set of locations. We used a total of 1394 LAI measurements from 29 sites spanning 4 continents and covering 15 crop types with corresponding Landsat satellite images. Best-fit functions for the LAI-VI relationships were generated and assessed in terms of crop type, vegetation index, level of radiometric/atmospheric processing, method of LAI measurement, as well as the time difference between LAI measurements and satellite overpass. These global LAI-VI relationships were evalu…
DIVERSITÀ BIOCULTURALE DI ALCUNI PAESAGGI MEDITERRANEI DI MONTAGNA
2016
The work presents a biocultural diversity interpretation of traditional Mediterranean agricultural landscapes. These landscapes are the result of complex interactions between biodiversity (at all levels, including species richness, ecosystem and biotope diversity) and cultural diversity, including material and immaterial aspects (architectural heritage, traditions, customs, local traditional agricultural practices, dialectal culture, etc.). The main theme is the traditional use of water related to traditional hydraulic systems, which in some areas date back to medieval times. Traditional agricultural landscapes grant a variety of ecosystem services and play a key role in biodiversity conser…
BioCultural Landscapes per la rigenerazione innovativa dei territori di montagna
2017
Simplification of agricultural systems, farmland abandonment, uncontrolled urbanization, together with global scale drivers, determine fast and unpredictable phenomena of hydrogeological instability, biodiversity decline and identity loss. Men should hence promote socio-economic resilience and place identity, using biocultural landscapes as a resource. These landscapes are the outcome of the historical relationship between man and nature, resulting from complex interactions between biodiversity (at all levels, including species richness, ecosystem and biotope diversity) and cultural diversity, including material and immaterial aspects (architectural heritage, traditions, customs, local trad…
