Livestock farming with care : summaries of essays

Wageningen UR is the country’s major research organisation in the field of livestock farming, providing the knowledge base for innovative livestock farming in our country and beyond and, as such, keen to play a role in the above mentioned debate. To this end an interdisciplinary task force was formed embodying a range of expertise, from livestock technology to system analysis and from economics to public administration. As one of the task force activities, Wageningen UR colleagues were invited to write an essay with their vision on specific aspects of this debate, based on their views and expertise. The result was a series of 30 essays, providing a wide overview of relevant issues with possible directions for solutions

NTA 8080 analysis of the JaLo pellet chain

JaLo Biopellets Twente intends to harvest biomass from landscape elements and turn that into pellets for energy purposes. The sustainability of these future operations was assessed through a specially developed sustainability framework consisting of several tools. This NTA 8080 study takes the JaLo chain sustainability assessment one step further. It tests the chain set-up for compliance with a series of formal sustainability requirements, as documented in the Dutch 8080 standard. In addition, the project framework tools are validated against this standard; it is analysed to what extend they cover each of the NTA 8080 sustainability requirements

Safety and Effectiveness of Struvite from Black Water and Urine as a Phosphorus Fertilizer

To ensure food supply, phosphorus must be recycled, for which an appealing method is using struvite fertilizer from human excreta. One struvite from black water and another from urine were assessed for safety under Dutch regulations, and for effectiveness as P fertilizer in a maize field experiment and a literature review. Both struvites contained 12% P, 12% Mg, 6% N, and 0.5-1.5% of several micronutrients. Struvites did not exceed Dutch regulations for heavy metals or pathogens, and based on literature, organic toxins should be far below regulatory limits. In this study and 18 others, struvite appears to have similar effectiveness to soluble fertilizer. Early in the season, 200 kg P2O5 ha-1 of black water struvite and soluble phosphorus improved maize performance (

Sustainability aspects of biobased applications : comparison of different crops and products from the sugar platform BO-12.05-002-008

In this study different uses of biomass are compared. In order to allow for a systematic comparison the study focuses on three different chemicals that can be produced from sugar. In this way it is also, in principle, possible to compare different crops for the production of the same product. The study focuses on the production of PLA (polylactic acid, a bioplastic), ethanol, and biopolyethylene (bio-PE, which is produced via ethanol). These three products can presently be produced from biomass and therefore form realistic cases. All three products are produced from sugars, and thus the systems can be decoupled at the sugar step. The sugar can be produced from different crops. In this study five different crops are compared: wheat, maize, sugar beet, sugar cane and Miscanthus. The sustainability aspects that we studied are non-renewable energy use (NREU), greenhouse gas (GHG) emission in the crop-product chain and direct land use for producing the bio-materials

The sociocultural sustainability of livestock farming: an inquiry into social perceptions of dairy farming.

Over the past 50 years, the scale and intensity of livestock farming have increased significantly. At the same time, Western societies have become more urbanised and fewer people have close relatives involved in farming. As a result, most citizens have little knowledge or direct experience of what farming entails. In addition, more people are expressing concerns over issues such as farm animal welfare. This has led to increasing public demand for more sustainable ways of livestock farming. To date, little research has been carried out on the social pillar of sustainable livestock farming. The aim of this study is to provide insights into the sociocultural sustainability of livestock farming systems. This study reviews the key findings of earlier published interdisciplinary research about the social perceptions of dairy farming in the Netherlands and Norway (Boogaard et al., 2006, 2008, 2010a and 2010b) and synthesises the implications for sociocultural sustainability of livestock farming. This study argues that the (sociocultural) sustainable development of livestock farming is not an objective concept, but that it is socially and culturally constructed by people in specific contexts. It explains the social pillar of the economics/ecological/social model sustainability in terms of the fields of tensions that exist between modernity, traditions and naturality – ‘the MTN knot’ – each of which has positive and negative faces. All three angles of vision can be seen in people's attitudes to dairy farming, but the weight given to each differs between individuals and cultures. Hence, sociocultural sustainability is context dependent and needs to be evaluated according to its local meaning. Moreover, sociocultural sustainability is about people's perceptions of livestock farming. Lay people might perceive livestock farming differently and ascribe different meanings to it than experts do, but their ‘reality’ is just as real. Finally, this study calls for an ongoing collaboration between social and animal scientists in order to develop livestock farming systems that are more socioculturally sustainable

Potential of LCA for designing technological innovations – the case of organic eggs

Ecological sustainability in agriculture is a concept that contains various environmental problems, which are caused by emission of pollutants and unsustainable use of limited resources, during different processes along the food chain. Technological innovations may help to improve ecological sustainability of food products. Preceding to the development of ecological sustainable technological innovations three questions need to be answered; 1) how ecological sustainable is the current production process, 2) which processes in the chain causes the highest ecological impact and 3) which production parameters significantly affect the ecological impact of these processes? The aim of this research is to demonstrate Life Cycle Assessment to the designers of technological innovations Life Cycle Assessment as a method to answer these questions, by means of a case study of the organic egg. In this study the LCA of organic eggs was calculated and compared to equivalent egg products. Ecological hotspots within the production chain were identified and the effectiveness of production parameters from the laying hen farm were identified on the LCA using sensitivity analysis. This LCA case study showed that organic eggs score worse than equivalent eggs on acidification, eutrophication and land use. Technological innovators should focus on ammonia emission from the laying hen farm to reduce the impact of acidification. Another focus should be nitrate leaching during concentrate production to reduce eutrophication. Innovative organic laying hen farmers may focus on a high feed conversion to improve the LCA of organic eggs in a broader sense. A shift from single tiered housing of laying hens to multi tiered housing with manure drying on manure belts, can reduce acidification 53% and eutrophication with 18%, almost enough to level out the 60% higher acidification and the 25% higher eutrophication of organic eggs compared to equivalent egg products

Options for sustainability improvement and biomass use in Malaysia : Palm oil production chain and biorefineries for non-food use of residues and by-products including other agricultural crops

The Division Biobased Products of the WUR institute A&F was approached by the Dutch Ministry of Agriculture, Nature and Food Quality with a policy support question about the potential of Bio-based economic developments in Malaysia. Malaysia is one of the major international trade partners of the Netherlands. Annually 4.500 – 5.000 million euro’s worth of goods are imported from Malaysia. The Netherlands are Malaysia’s most important trading partner within the EU. The volume of agricultural commodities and especially palm oil products are substantial and the use of biobased resources for the generation of energy or biofuel has created a fierce debate on the sustainability of expansion of use of the biomass resources. In the context of the international policy to support the transition towards a biobased economy the potential resources that can be used for production of materials, chemicals and energy needs to be indentified. This report is reviewing the options that the current Malaysian agro-forestry sector may provide for sustainable developments. The main conclusions are that especially the currently underutilized residues and polluting wastes from the palm oil production have big potential for value addition and technical product development that also could substantially contribute to the reduction of greenhouse gas emissions. Examples can be found in fermentation of residues and effluents to produce bio-gas / ethanol or bioplastics but also fibre boards and building materials. Demonstration on pilot scale of such technologies could create new business and bilateral interactions between Malaysia and The Netherlands
