“…The warnings continue [109,[112][113][114][115][116][117][118][119]. Yet many scientists still tend to treat population growth as an exogenous variable, when it should be considered an endogenous one-indeed, a central factor [120].…”

The aim of the present work was to assess and compare energy inputs and outputs of various crop managements in 2011-2012. Two main crops on arable land and three permanent grasslands were investigated. Silage maize (Zea mays L.) and winter wheat (Triticum aestivum L.) were grown on lowland, whilst two semi-natural grasslands and grassland infested by tufted hair-grass (Deschampsia caespitose (L.) P. Beauv) were located in mountainous regions of Slovakia. In these crops and grasslands the dry matter yield was measured and subsequently the supplementary energy, energy gain and unifying energy value -tonne of oil equivalent (TOE) -were calculated. Silage maize with 233.37 GJ*ha -1 has provided the highest energy gain. In the group of grasslands, grassland infested by tufted hair-grass has offered the highest energy gain (59.77 GJ*ha -1 ). And this grassland had the lowest requirement on the supplementary energy (3.66 GJ*ha -1 ), contrary to silage maize with highest one (12.37 GJ*ha -1 ). The total energy potential of the crop biomasses was confronted with energy consumption in Slovakia. Winter wheat has the biggest energy potential, but it could cover only 19.6% and 11.3% total consumption of electricity or natural gas, respectively. Large area of permanent grasslands and their spatial location make them an important energy reservoir for bioenergy production. But, it is not possible to replace all consumed fossil fuels by bioenergy from these tested renewable energy sources. AbstraktCieľom predkladanej štúdie bolo zhodnotiť a porovnať vstupy a výstupy energie pre pestovateľské technológie silážnej kukurice (Zea mays L.) a pšenice letnej (Triticum aestivum L.) v nížinnej oblasti a troch trvalých trávnych porastov (dva poloprírodné a porast osídlený metlicou trstnatou, Deschampsia caespitose (L.) P. Beauv) v horských oblastiach Slovenska počas obdobia 2011-2012. Plodiny boli porovnávané z hľadiska úrod sušiny, dodatkovej energie a energetického zisku prevedením na zjednocujúcu energetickú veličinu -tona ropného ekvivalentu (TOE). Najvyšší energetický zisk bol dosiahnutý pri silážnej kukurici (233.37 GJ*ha -1 ). V skupine trvalých trávnych porastov dominoval porast osídlený metlicou trstnatou so ziskom energie (59.77 GJ*ha -1 ). Tento trávny porast vyžadoval na svoju prevádzku veľmi nízky vklad dodatkovej energie (3.66 GJ*ha -1 ) v porovnaní so silážnou kukuricou (12.37 GJ*ha -1 ). Celkový potenciál rastlinnej biomasy bol konfrontovaný so spotrebou energie na Slovensku. Najpriaznivejší energetický potenciál poskytla pšenica, ale aj napriek tomu by dokázala pokryť iba 19,6% spotreby elektrickej energie a 11,3% spotreby zemného plynu. Vysoká výmera plôch trvalých trávnych porastov a oblasti kde sa nachádzajú, sú dôvodom, prečo sa pokladajú za významný rezervoár bioenergie. Nie je však možné nahradiť spotrebu fosílnych palív energiou biomasy testovaných plodín.Kľúčové slová: energetický potenciál, kukurica, metlica trstnatá, obnoviteľná energia, pšenica letná, tona ropného ekvivatentu, trvalý trávny porast Deta...

“…One hundred years after the founding of the first ecological societies (the British Ecological Society in 1913 and the Ecological Society of America in 1915), the field of ecology is faced with an extraordinary challenge: to elucidate the planetary boundaries for human activities (Rockströ m et al 2009a(Rockströ m et al , 2009b and inform the global governance of the environments rapidly being altered by our species (Mace 2013). In the search for sustainable solutions that are grounded in the natural and social sciences (Burger et al 2012), geographical, institutional, and disciplinary barriers in the scientific landscape must be less predominant. GCIPs provide one way by which communities can get together to help break down these barriers for the benefit of their disciplines and the generations that follow.…”

Abstract. We present a case for using Global Community Innovation Platforms (GCIPs), an approach to improve innovation and knowledge exchange in international scientific communities through a common and open online infrastructure. We highlight the value of GCIPs by focusing on recent efforts targeting the ecological sciences, where GCIPs are of high relevance given the urgent need for interdisciplinary, geographical, and cross-sector collaboration to cope with growing challenges to the environment as well as the scientific community itself. Amidst the emergence of new international institutions, organizations, and meetings, GCIPs provide a stable international infrastructure for rapid and long-term coordination that can be accessed by any individual. This accessibility can be especially important for researchers early in their careers. Recent examples of early-career GCIPs complement an array of existing options for early-career scientists to improve skill sets, increase academic and social impact, and broaden career opportunities. We provide a number of examples of existing early-career initiatives that incorporate elements from the GCIPs approach, and highlight an in-depth case study from the ecological sciences: the International Network of Next-Generation Ecologists (INNGE), initiated in 2010 with support from the International Association for Ecology and 20 member institutions from six continents.

Abstract: Global consumption rates of vital resources suggest that we have surpassed the capacity of the Earth to sustain current levels, much less future trajectories of growth in human population and economy.
