Grassnuitkevers, een toekomstige bedreiging in gazons?
Vliet, Arnold van - \ 2016
lawns and turf - plant pests - curculionidae - external traits - properties - host plants - netherlands - spain - usa

Met de uitbreiding van grassnuitkevers in diverse landen zoals de Verenigde Staten en Spanje neemt de zorg toe dat er zich ook grassnuitkeversoorten in Nederland gaan vestigen door het verslepen van plantmateriaal of via vakantiegangers. Grassnuitkevers zijn vooral schadelijk voor gras, maar doen zich ook te goed aan mais, tarwe en varens.

This study assessed the competitiveness of the EU food industry benchmarked against USA, Australia, Brazil and Canada. This assessment is based on trade indicators (Relative Net trade advantage and export share on the world market) and on economic indicators (value added, labour productivity and share value added in total manufacturing). This study is an update of an earlier study executed in 2007. The overall competitiveness performance of the EU28 (intra-EU trade excluded) remained weak: the three economic indicators weakened and the trade indicators improved in period (2) 2008-2012 compared to period (1) 2003-2007. The position in period 2 was even weaker than the relative weak position in period 1. Brazil remained the strongest and the USA became strong.

In 2014, the non-governmental organisation Wakker Dier in the Netherlands criticised ING for financing animal farms outside the European Union (EU). The NGO expressed its concern that local regulation would not sufficiently guarantee animal welfare standards up to the level guaranteed under EU regulations. Early 2015, LEI Wageningen UR was requested to identify potential detrimental activities in the United States of America (USA) animal husbandry sector due to gaps between EU and USA legislation and local animal welfare standards applied in the USA. Activities covered by ING clients in the USA and thus in scope of this research involve pigs, layers, broilers, veal calves, dairy cows and beef cows. The aim of this report is to provide a qualified comparison of animal welfare standards in the USA and the EU and to identify animal welfare and other potential ethical issues within animal farming in the USA and to identify critical issues on which ING is advised to take a strategic position.
Stimuli for municipal responses to climate adaptation: insights from Philadelphia – an early adapter
Uittenbroek, C.J. ; Janssen-Jansen, Leonie ; Runhaar, H.A.C. - \ 2016

climate adaptation - stimuli - governance approaches - Philadelphia - institutional entrepreneurship - political leadership
An in-depth understanding of these stimuli is currently lacking in literature as most research has focussed on overcoming barriers to climate adaptation. The aim of this paper is to identify stimuli for municipal responses to climate adaptation and examine how they influence the governance approach to addressing climate adaptation through explorative case study research. Fort this, an early adapter was selected as case: Philadelphia (USA). By reconstructing the organization of two municipal responses to climate adaptation in this city, we have been able to identify stimuli and gain insight in the city’s governance approach. The reconstruction is based on data triangulation that consists of semi-structured interviews with actors involved in these responses, policy documents and newspaper articles. The research illustrates the importance of stimuli such as strategically framing climate adaptation within wider urban agendas, political leadership and institutional entrepreneurs. Moreover the research reveals that it is the combination of stimuli that influences the governance approach to climate adaptation. Some stimuli will trigger a dedicated approach to climate adaptation, while others initiate a mainstreaming approach. This research is important especially to municipalities to recognize stimuli within their own (policy) context and subsequently, make informed decisions to exploit all or some of these stimuli to initiate a governance approach to climate adaptation.

In de jaren vijftig gold de boer nog als een ‘achterlijke lomperik’, die via speciale streekverbeteringsprogramma’s de twintigste eeuw ingeloodst moest worden. Nu boeren agrarische ondernemers zijn geworden, overheerst de nostalgie naar het landleven in de jaren vijftig.

The United States (US) is among the global hotspots of nitrogen (N) deposition and assessing the temporal trends of wet N deposition is relevant to quantify the effectiveness of existing N regulation policies and its consequent environmental effects. This study analyzed changes in observed wet deposition of dissolved inorganic N (DIN = ammonium + nitrate) in the US between 1985 and 2012 by applying a Mann–Kendall test and Regional Kendall test. Current wet DIN deposition (2011–2012) data were used to gain insight in the current pattern of N deposition. Wet DIN deposition generally decreased going from Midwest > Northeast > South > West region with a national mean rate of 3.5 kg N ha-1 yr-1. Ammonium dominated wet DIN deposition in the Midwest, South and West regions, whereas nitrate and ammonium both contributed a half in the Northeast region. Wet DIN deposition showed no significant change at the national scale between 1985 and 2012, but profound changes occurred in its components. Wet ammonium deposition showed a significant increasing trend at national scale (0.013 kg N ha-1 yr-2), with the highest increase in the Midwest and eastern part of the South region. Inversely, wet nitrate deposition decreased significantly at national scale (-0.014 kg N ha-1 yr-2), with the largest reduction in the Northeast region. Overall, ratios of ammonium versus nitrate in wet deposition showed a significant increase in all the four regions, resulting in a transition of the dominant N species from nitrate to ammonium. Distinct magnitudes, trends and patterns of wet ammonium and nitrate deposition suggest the needs to control N emissions by species and regions to avoid negative effects of N deposition on ecosystem health and function in the US.

This is the first paper to analyze the impact of biofuels on the price transmission along the food chain. We analyze the U.S. corn sector and its vertical links with food and ethanol (energy) markets. We find that biofuels affect the price transmission elasticity in the food chain compared to a no biofuel production situation but the effect depends on the source of the market shock and the policy regime: the price transmission elasticity declines under a binding blender’s tax credit and a food market shock. Our results also indicate that the response of corn and food prices to shocks in the corn and/or food markets is lower in the presence of biofuels. Finally, the sensitivity analyses indicate that our results are robust to different assumptions about the model parameters.

De verwachting is dat door klimaatverandering de intensiteit van droogte zal toenemen in verschillende gebieden op de wereld. Uitkomsten van vijf hydrologische modellen in combinate met drie klimaatmodellen voor het A2 emissie scenario zijn gebruikt om effecten van klimaatverandering op hydrologische droogte te analyseren voor verschillende stroomgebieden. Droogtes en lage afvoeren (maandelijkse 20ste percentiel waarden, Q20) zijn geïdentificeerd uit de uitkomsten van de hydrologische modellen voor een historische periode (1971–2000) en een periode in de toekomst (2071–2100). De gesimuleerde lage afvoeren voor de historische periode zijn vergeleken met geobserveerde lage afvoeren van de verschillende stroomgebieden. De modelcombinaties (combinatie van een klimaatmodel en een hydrologisch model), die de beste resultaten gaven, zijn gebruikt voor verdere analyse. In koude klimaten werd een verschuiving in het hydrologische regime (de piek van sneeuwsmelt zal eerder optreden) waargenomen en een verhoging van de lage afvoeren tussen de historische periode en de periode in de toekomst. Voor aride klimaten gaven de modelcombinaties aan dat omstandigheden nog droger zullen worden in de toekomst. Voor vochtige klimaten werden zowel drogere als nattere situaties verwacht op basis van de modelcombinaties

De Amerikaanse natuurbeschermer Ernest Oberholtzer (1884-1977) is ten onrechte in de vergetelheid geraakt. Hij werkte in een omgeving die vijandig stond ten opzichte van de natuurbescherming, maar wist door zijn verhalen, netwerken en optreden toch invloed uit te oefenen. Zijn leven en werk zijn ook voor ons in Nederland nog steeds, en misschien wel steeds meer, een studie waard.

This study compares the relative influences of physiography and anthropogenic pressures on river biota at catchment, riparian corridor, and reach scales. Environmental data, catchment and riparian corridor land use, anthropogenic modifications and biological data were compiled for 301 French sites sampled from 2005 to 2008. First, relationships between anthropogenic pressures and fish and macroinvertebrate assemblages were analysed using redundancy analysis. Second, the influences of physiography and the three scales of human pressures on biological assemblages were measured using variance partitioning. Distributions of fish and macroinvertebrate taxa along the pressure gradients agreed with bio-ecological knowledge. At the reach scale, assemblage variability among the 301 French sites was related to the presence of an impoundment and to poor water quality, while at larger scales it was linked to a gradient from forest to agricultural covers. In addition, a large proportion of the explained variability in assemblage composition was related to complex interactions among factors (~40%) and to physiographic variables (~30%). Furthermore, our results highlight that catchment land use better reflects local water quality impairments than hydromorphological degradations. Finally, this study supports the idea that human pressure effects on river communities are linked at several spatial scales and must be considered jointly.

Two styles of river flood management can be distinguished: dike reinforcement and the more sustainable ‘Room for River’ option. This paper investigates public adherences to these two management styles and whether their adherence correlates with their Visions of Nature. The focus is especially on people’s image of the appropriate human/nature relationship, i.e. Mastery over nature, Stewardship of nature, Partnership of nature or Participation in nature. Other variables that are part of the analysis are the respondents’ sense of place, safety perception and background variables. The results of a written survey among riverside residents in France, Germany and the Netherlands (N = 1811) show high adherences to the Room for River style and a rejection of dike reinforcement. A regression analysis shows that adherence to the Room for River style correlates with adherence to the image of Stewardship, while adherence to dike reinforcement is predicted by Mastery over nature. Thus, according to the public a policy shift from dike reinforcement to a more sustainable style is seen as a fundamental one, connected to a change in environmental ethics.
