The use of very long spatial datasets from satellites has opened up numerous opportunities, including the monitoring vegetation phenology over course time. Considering importance grassland systems and influence climate change on their phenology, specific objectives this study are: (a) to identify a methodology for reliable estimation phenological dates satellite index (i.e., kernel normalized difference index, kNDVI) (b) quantify changes that have occurred period 2001–2021 in representative...
Relative soil water content (RSWC) is widely used to characterize the impact of stress (WS) on vegetation. In bi-layer ecosystems, such as olive groves, this must be primarily estimated for tree component, which, having greater rooting depth, responds more slowly WS than understory grass. This complicates application methods RSWC prediction, which properly adapted consider deeper layer influential trees. The current study investigates modification a recently proposed simulation method based...
Olive tree cultivation is currently a dominant agriculture activity in the Mediterranean basin, where increasing impact of climate change coupled with inefficient management olive groves negatively affecting oil production and quality some marginal areas. In this context, satellite imagery may help to monitor crop growth under different environmental conditions, thus providing useful information for optimizing grove final production. However, spatial resolution freely-available products not...
Future climate change is expected to significantly alter the growth of vegetation in grassland systems, terms length growing season, forage production, and climate-altering gas emissions. The main objective this work was, therefore, simulate future impacts foreseen context two pastoral systems central Italian Apennines test different adaptation strategies cope with these changes. PaSim simulation model used for purpose. After calibration by comparison observed data aboveground biomass (AGB)...
Current vegetation of alpine grasslands has been shaped by the combination natural ecological factors (such as climate, soil, topography) and human activities, mainly represented animal grazing agricultural practices. An assessment these can explain present composition plant communities help to evaluate future development rangeland vegetation. Nowadays, analysis botanical is a major importance in order propose appropriate management plans for sustainable exploitation pastoral resources their...
Climate change is currently threatening agro-pastoral systems around the world. Increased temperature and prolonged drought periods are reducing capacity of these environments to provide several ecosystem services their potential mitigate climate change. In this context, grasslands pastures monitoring gains a relevant importance for improving farm management productivity, farmer incomes reduce input wastage greenhouse gases emissions. perspectives, many crop models have been adopted with...
