    Abstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.

  3. 2. Improvement of the GPP estimations for Sudan using the evaporative fraction as water stress factor

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maria Angela Dissegna; [2016]
    Keywords : semi-arid regions; light use efficiency models; evaporative fraction; gross primary production; Physical Geography and Ecosystem analysis; GEM; Earth and Environmental Sciences;

    Abstract : Estimation of GPP in Sudan using the evaporative fraction as water stress factor The Gross Primary Production "GPP" quantifies the amount of carbon entering an ecosystem. It is an ecosystem service since it is a source of energy for all organisms and it is estimated to reduce atmospheric CO2 in about 123 Pg C per year at the global scale. READ MORE

    Abstract : Nowadays importance of water balance regarding measurements and water cycle pathways are of prime interest in a new perspective. Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. READ MORE
