    Mondiale ecosystemen staan zwaar onder druk. Het beschermen van waardevolle natuurgebieden is niet voldoende om de afname van de biodiversiteit te verminderen, maar blijft wel noodzakelijk. Om het tempo van het biodiversiteitverlies fors af te remmen, zijn structurele veranderingen in consumptie en productie nodig. Er valt veel winst te behalen bij vermindering van de vleesconsumptie. Daarnaast zijn vooral in de land- en bosbouw, visserij en energievoorziening veranderingen nodig. Het Planbureau identificeert nieuwe strategieën voor VN-top in Nagoya

    land-use scenarios - biomass energy - environmental-impact - water-use - palm oil - exploration - biofuels - habitat - willow - diet
    he growing use of bioenergy goes hand in hand with a heated public debate, in which conflicting claims are made regarding the amount of biomass that can be sustainably used for this purpose. This article assesses the current knowledge on biomass resource potentials and interrelated factors such as water availability, biodiversity, food demand, energy demand and agricultural commodity markets. A sensitivity analysis of the available information narrows the range of biomass potentials from 0–1500 EJ/yr to approximately 200–500 EJ/yr in 2050. In determining the latter range, water limitations, biodiversity protection and food demand are taken into consideration. Key factors are agricultural efficiency and crop choice. In principle, global biomass potentials could meet up to one third of the projected global energy demand in 2050.

    Long-distance dispersal: the key to plant invasiveness under climate change?
    Meyer, K. ; Oorschot, M. van; Putten, W.H. van der - \ 2009
    In: From global change to molecular ecology, 39th Annual Conference GFOE (GfÖ) 2009 Dimensions of ecology, Bayreuth, Germany, September 14-18, 2009. - Bayreuth : University of Bayreuth - p. 154 - 154.
    Current climate warming contributes to massive range shifts of plants and animals from lower to higher latitude. If plants shift their range faster than their enemies, the plants may eventually escape and become invasive in the new range (enemy release hypothesis). Invasion success can, therefore, depend on the dispersal capacity of the plant and its enemies. Taking a simulation modeling approach, we investigated the effect of the relative dispersal capacity of a plant and its belowground pathogen on the degree of range expansion and enemy release. We contrasted scenarios with and without climate change and included long-distance dispersal of plant and pathogen. In our scale-explicit model, population dynamics emerged from individual interactions in a field-scale grid of a few hectares and was extrapolated to a regional-scale grid covering a transeuropean temperature gradient. Plant range expansion increased with the dispersal capacity of the plant, but was independent of pathogen dispersal capacity. Climate change did not markedly affect range expansion, but had a positive effect on enemy release and the number of successful long-distance dispersal events. Interestingly, this ‘guerilla pattern’ vanished when plant dispersal capacity was lower than pathogen dispersal capacity. We conclude that long-distance dispersal can be the key to the invasive success of range expanding plants under climate change, but fast enemies can impede guerilla plants

    This study provides a comprehensive assessment of global biomass potential estimates, focusing on the various factors affecting these potentials, such as food supplies, water use, biodiversity, energy demands and agro-economics. In addition, a number of studies analysing GHG balances of bioenergy are discussed. After an extensive inventory of recent studies in the different areas (food, water, biodiversity, agro-economics and energy demand); this study integrates the complicated linkages between the various factors, quantifying the consequences of the linkages and knowledge found in the inventory within the limits of the presently available models. The results are translated into an overview of the uncertainties in biomass resource potential estimates and summarises the available knowledge and knowledge gaps. This analysis leads to policy relevant recommendations for sustainable biomass use in the future including R&D needs. Social, legal and institutional aspects of biomass production and use ¿ although of large political relevance ¿ have not been part of this study. Including these aspects might reduce the available biomass potentials compared to technical estimates discussed in this study

    A scenario study from 2000 to 2050 has been performed (by Natuur en Milieuplanbureau, UNEP and WCMC) to explore the effects of future economic, demographic and technical developments on environmental pressures and global biodiversity. Policy options that affect global biodiversity were analysed on their contribution to the 2010 biodiversity targets agreed upon under the Convention on Biological Diversity (CBD). The mean species abundance of natural occurring species was used as indicator for biodiversity. To analyse the economic and environmental consequences of changes in global drivers and policies, we developed a global economic-biophysical framework by combining the extended GTAP model (Van Meijl et al., 2005) with the IMAGE model (Alcamo et al., 1998; IMAGE Team, 2001).
    Characterization of the role of para-aminobenzoic acid biosynthesis in folate production by Lactococcus lactis

    The pab genes for para-aminobenzoic acid (pABA) biosynthesis in Lactococcus lactis were identified and characterized. In L. lactis NZ9000, only two of the three genes needed for pABA production were initially found. No gene coding for 4-amino-4-deoxychorismate lyase (pabC) was initially annotated, but detailed analysis revealed that pabC was fused with the 3' end of the gene coding for chorismate synthetase component II (pabB). Therefore, we hypothesize that all three enzyme activities needed for pABA production are present in L. lactis, allowing for the production of pABA. Indeed, the overexpression of the pABA gene cluster in L. lactis resulted in elevated pABA pools, demonstrating that the genes are involved in the biosynthesis of pABA. Moreover, a pABA knockout (KO) strain lacking pabA and pabBC was constructed and shown to be unable to produce folate when cultivated in the absence of pABA. This KO strain was unable to grow in chemically defined medium lacking glycine, serine, nucleobases/nucleosides, and pABA. The addition of the purine guanine, adenine, xanthine, or inosine restored growth but not the production of folate. This suggests that, in the presence of purines, folate is not essential for the growth of L. lactis. It also shows that folate is not strictly required for the pyrimidine biosynthesis pathway. L. lactis strain NZ7024, overexpressing both the folate and pABA gene clusters, was found to produce 2.7 mg of folate/liter per optical density unit at 600 nm when the strain was grown on chemically defined medium without pABA. This is in sharp contrast to L. lactis strains overexpressing only one of the two gene clusters. Therefore, we conclude that elevated folate levels can be obtained only by the overexpression of folate combined with the overexpression of the pABA biosynthesis gene cluster, suggesting the need for a balanced carbon flux through the folate and pABA biosynthesis pathway in the wild-type strain.

    Visteelt is belangrijk voor de wereldvoedselproduktie. Wereldwijd wordt 107 ton vinvis geteeld. De zalm neemt daarbij, vooral in Noorwegen, Schotland, Chili en Canada, een belangrijke plaats in. De Nederlandse wateren zijn ongeschikt voor de teelt van zalmen, maar regenboogforellen (Oncorhynchus mykiss, Walbaum) kunnen in ons land wel worden geteeld. De regenboogforel is een zoetwatervis welke zich ook aan een zout milieu kan aanpassen. In Nederland zijn ongeveer 25 bedrijven waar op een of andere manier regenboogforellen worden gehouden, hoofdzakelijk in zoetwater. ln de Nederlandse kustwateren wordt de teelt van regenboogforellen bemoeilijkt door de (te) hoge watertemperaturen tijdens de zomerperiode. Boven 17°C wordt bij deze vissen het metabolisme dermate bemoeilijkt dat ze sterven, mogelijk door een auto-intoxicatie met CO2 (3). Het is toch mogelijk gebleken in het Nederlands marien milieu regenboogforellen tot 600 -1000 gram te kweken: hiertoe wordt na de zomerperiode gestart met forellen van 150 g, welke vervolgens gedurende 10 maanden in kooien op zee worden gehouden. Na het afmesten met caroteenrijk voer worden deze vissen vermarkt onder de naam 'zalmforel'
