Publication date: November 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 66 Author(s): H.J. Nijland , H.C.M. van Trijp , M.N.C. Aarts , P.T.M. Ingenbleek Modern livestock farming systems typically stand out in terms of production efficiency and chain integration. However, the legitimacy of animal production systems is currently being questioned, due to social and ecological concerns. The term ‘careful’ livestock farming has been coined to reflect a production system that addresses this broader range of concerns. In this paper we argue that although the term ‘careful’ provides a useful start...

Maximizing the nitrogen efficiency of a prototype mixed crop-livestock farm in The Netherlands
Publication date: November 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 66 Author(s): E.A. Lantinga , E. Boele , R. Rabbinge This paper describes the year-over-year improvement of the nitrogen (N) efficiency in a prototype mixed farm system through the implementation of a coherent set of ecotechnological adjustments. This farm, the former APMinderhoudhoeve, was located on a marine clay loam soil in Oostelijk Flevoland, the Netherlands, reclaimed from the sea in the late 1950s. The designed farm structure was representative for the Dutch soil-bound agriculture in the late 1990s in terms of food crop...

Assessing and controlling health risks from animal husbandry
Publication date: November 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 66 Author(s): Tjeerd Kimman , Maarten Hoek , Mart C.M. de Jong A fierce debate is going on about the risks of animal husbandry for human health and the quality of control measures to reduce such risks. Risks include the occurrence of infectious diseases, in particular zoonoses, and the high antibiotic use in livestock production contributing to emergence of antibiotic resistance and its spread from animals to humans. On the other hand, many infectious diseases of animals and humans have been eliminated, including brucellosis, t...

Livestock Farming with Care: towards sustainable production of animal-source food
Publication date: November 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 66 Author(s): M.C.Th. Scholten , I.J.M. de Boer , B. Gremmen , C. Lokhorst This paper introduces a concept for sustainable production of animal-source food. This concept of “Livestock Farming with Care” is founded on care ethics with an integrated approach based on four principles: One Health (i.e. healthy and safe for animals and humans); Customized Care (i.e. from the individual animal's perspective and integrity); No Nuisance (i.e. from an environmental and societal perspective) and Credible Performance (i.e. from an ec...

Vegetable production in the Red River Delta of Vietnam. I. Opportunities and constraints
Publication date: 18 December 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 67 Author(s): Pham Thi Thu Huong , A.P. Everaarts , J.J. Neeteson , P.C. Struik An overview is given of the natural, socio-economic, agronomical and marketing conditions for vegetable production in the Red River Delta (RRD) of Vietnam. The seasonal variation in temperature in the RRD is the main determinant for the production season of vegetables. Heavy rainfall in the hot season increases production risks, as it may physically damage crops. Frequent rainfall in this period may enhance disease incidence. Landholdings are sm...

State governance of pesticide use and trade in Vietnam
Publication date: 18 December 2013 Source:NJAS - Wageningen Journal of Life Sciences, Volume 67 Author(s): Pham Van Hoi , Arthur Mol , Peter Oosterveer Vietnam is facing serious challenges with respect to the amount and toxicity of the pesticides used. With hardly any domestic pesticides production, Vietnam experienced an exponential growth of both the quantity and the value of imported pesticides in recent years. And the increasing import of newly formulated (and safer) pesticides has not replaced or reduced the highly toxic pesticides with low efficacy. The improper use of pesticides by farmers (too high dosages, ...

A Bayesian Belief Network to Infer Incentive Mechanisms to Reduce Antibiotic Use in Livestock Production
The objective of this paper was to develop a Bayesian belief network (BBN) to analyze how these factors can directly and indirectly influence antibiotic use. Since both factors are not directly observable (i.e., latent), they were inferred from related observable variables (i.e., manifest variables). Using farm accounting data and registration data on antibiotic use and veterinary services in specialized finisher pig farms over the period 2007-2010, a confirmatory factor analysis was carried out to construct the two latent factors. Antibiotic use is quantified as the number of days per year in which an average pig is treat...

Energy use and greenhouse gas emissions in organic and conventional farming systems in the Netherlands
Publication date: 7 March 2014 Source:NJAS - Wageningen Journal of Life Sciences, Volume 68 Author(s): Jules F.F.P. Bos , Janjo de Haan , Wijnand Sukkel , René L.M. Schils Organic agriculture is often considered to contribute to reducing energy use and greenhouse gas (GHG) emissions, also on a per unit product basis. For energy, this is supported by a large number of studies, but the body of evidence for GHGs is smaller. Dutch agriculture is characterized by relatively intensive land use in both organic and conventional farming, which may affect their performance in terms of energy use and GHG emissions. This pape...

Economic and environmental effects of a flat rate for Dutch agriculture
The objective of this research is to give insights into the production, income and environmental effects of the introduction of a flat rate for Dutch agriculture that is lower than the present average direct income payment. For this purpose, a detailed agri-environmental programming model for Dutch agriculture is used. Results of a flat rate scenario are compared to a reference scenario comparing agricultural production in the Netherlands in 2020 in a situation without a flat rate. Results show that total gross margin in Dutch agriculture decreases because of the flat rate with 7%. The supply of starch potatoes and cow mil...
