Накратко на български
Влиянието на мусонните дъждове и паша върху растителността в тропическите екосистеми на Австралия се анализира чрез сензори и сателитни данни. Това помага за по-доброто предвиждане на въглеродния цикъл и управлението на пасищата при променящ се климат.

Final Activity and Management Report Summary - CASOAR (Landscape-scale Carbon cycle Analysis using hyperspectral remotely Sensed data Of plant and ecosystem functionAl diveRsity)
This project is within the scope of studies examining the impact of climate change on the carbon cycle of terrestrial ecosystems. The research has focused on the seasonal and inter-annual leaf dynamics (ecosystem phenology) of water-controlled tropical ecosystems in Australia. Ecosystem phenology is a key component of earth system models as it determines the favourable period for carbon and water uptake by vegetation. The specific objective of this work was to monitor, understand, and model the influence of monsoonal rainfalls and grazing pressure on the phenology of Australian tropical ecosystems. This research is timely because worldwide changes in the timing and intensity of rainfalls are forecasted for semiarid ecosystems. Major scientific achievements have been (i) the installation of an Environmental Sensor Network in semi-arid tropical grasslands providing the crucial, though often overlooked, ground calibration of the remote sensing data, (ii) the development and testing of an ecohydrological model that improves our capacity to predict phenology and biomass dynamics in water-controlled ecosystems at the landscape and regional scales, (iii) steps towards a better understanding and representation of the role of plant functional diversity in carbon and water biogeochemical cycling. These findings are relevant to the sustainable management of pasture resources and forage for meat, milk and wool production. The project has fostered emerging and innovative partnership among academics and non-academics to improve our understanding of the dynamics and functioning of water-controlled ecosystems in the context of a changing climate.

Цел на проекта
The applicant's objective is to learn and develop new methods, especially hyperspectral remote sensing, for integrating plant functional diversity changes into landscape-scale carbon cycle models. Climate and land-use changes affect patterns of plant functional diversity, which in turns are strong drivers of the carbon cycle. Plant functional diversity allows to consider carbon cycle-related processes operating on large time and spatial scales - from local and transient ecosystem response to long-term impact of vegetation changes on carbon budgets. Here, we propose to explicitly incorporate temporal and spatial patterns of plant functional diversity into landscape-scale terrestrial-carbon-cycle models using hyperspectral remotely sensed data. As a first step, remote sensing will be used for the mapping and landscape-modelling of key functional traits ¿ canopy nitrogen and water content, light-use efficiency etc ¿ known to determine major carbon-cycle related processes. As a second step, we will integrate these distribution models of functional diversity into terrestrial biogeochemical models with the aim to extend local measurements of CO2 fluxes both spatially and temporally. The project will be conducted in two contrasted Australian landscapes - tropical savannas and evergreen Eucalyptus forests - for which ecosystem properties and continuous on-ground measurements of CO2 fluxes are available. This project aims at coupling the applicant's expertise in plant functional ecology with biogeochemistry, climatology and remote sensing. The competencies acquired in a world leading place for carbon cycle science - CSIRO, Australia - will open new research avenues for the applicant when returning to his host institution ¿ University of Grenoble I, France. This project meets the concern of the European Community environmental policies relating to the understanding and forecasting of the carbon cycle, including its feedbacks with human components.
