Integrated impact assessment of climate and socio-economic change on dairy farms in a watershed in the Netherlands
This study uses a bio-economic farm model to assess impacts of climate and socio-economic change on dairy farms in a sandy area in the Netherlands. Farm data from the Farm Accountancy Data Network provided information on the current production levels and available farm resources. First, the farm plans of individual farms were optimized in the current situation to benchmark farms and assess the current scope for improvement. Secondly, simulations for two scenarios were included: a Global Economy with 2°C global temperature rise (GE/W+) and a Regional Community with 1°C global temperature rise (RC/G). The impacts of climat...

Explaining production expansion decisions of Dutch dairy farmers
The objective of this study is to analyse which factors determine milk production expansion by Dutch dairy farmers. A conceptual model is developed that shows how policies, market conditions, and farmers’ values and goals affect their expansion decisions. This conceptual model shows that not only economic, but also social and environmental variables are important factors in expansion decisions of Dutch dairy farmers. Zooming in on the dynamic decision making process itself, we combine three investment theories to explain investment decisions. This framework is the basis for a dynamic random effects probit model that is u...

Energy inputs and greenhouse gas emissions associated with small-scale farmer sugarcane cropping systems and subsequent bioethanol production in Japan
Publication date: Available online 21 December 2015 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Takahiro Nakashima, Shoko Ishikawa Fossil fuel energy consumption and greenhouse gas emissions were estimated in cropping systems of sugarcane (Saccharum officinarum L.) and the subsequent production of ethanol in order to evaluate the feasibility of bioethanol production by small-scale farmers in the Tanegashima Island, one of the major areas of sugarcane production in Japan. The current cropping system and an alternative system were compared using Life Cycle Assessment and the results are discussed in ...

Evaluation of producing and marketing entire male pigs
In conclusion, boar tainted meat was rated as less pleasant by consumers compared to meat of gilts and non-tainted boar meat, indicating the need of detection as a safety net at the slaughter line. Breeding was an effective preventive measure to reduce boar taint. Farms with appropriate management, feeding and housing conditions have reduced levels of mounting and aggressive behaviour. Human nose scores were a better predictor of the rank order of consumer perception, compared to skatole levels and to androstenone levels. (Source: NJAS Wageningen Journal of Life Sciences)

Adapting spring wheat breeding to the needs of the organic sector
Publication date: Available online 21 December 2015 Source:NJAS - Wageningen Journal of Life Sciences Author(s): A.M. Osman, C.J.M. Almekinders, P.C. Struik, E.T. Lammerts van Bueren Organic farmers and food processors need plant varieties that are adapted to their crop husbandry and processing practices. Such varieties are scarce as the mainstream breeding sector focuses on developing varieties for the conventional product chain that has different goals and practices. In this paper we study the case of the Dutch bread production chain to assess options that might enhance the availability of varieties suitable ...

Private Environmental Governance in the Ethiopian Pesticide Supply Chain: Importation, Distribution and Use
Publication date: Available online 18 December 2015 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Belay T. Mengistie, Arthur P.J. Mol, Peter Oosterveer Agricultural pesticides are important chemicals that are used to mitigate crop damage or loss and improve productivity. However, pesticides may cause negative environmental and human health effects depending on their specific distribution and use. Securing environmental safety and sustainability of pesticide distribution and use is widely seen as an important challenge for pesticide governance. This paper analyses how, why and under what circumstanc...

Understanding perceptions of potato seed quality among small-scale farmers in Peruvian highlands
Publication date: Available online 19 December 2015 Source:NJAS - Wageningen Journal of Life Sciences Author(s): C. Urrea-Hernandez, C.J.M. Almekinders, Y.K. van Dam The increased opportunities of smallholder farmers for commercial production of native potato varieties have resulted in an interest to support production and use of quality seed tubers of these varieties by the formal sector. In this context, a study was carried out to explore farmer perception of seed quality and the differences with formal expert perceptions of seed quality. It introduces Means-End-Chains methodology as a novel approach in studyin...

Systemic problems affecting co-innovation in the New Zealand Agricultural Innovation System: Identification of blocking mechanisms and underlying institutional logics
This study identifies systemic problems in the New Zealand Agricultural Innovation System (AIS) in relation to the AIS capacity to enact a co-innovation approach, in which all relevant actors in the agricultural sector contribute to combined technological, social and institutional change. Systemic problems are factors that negatively influence the direction and speed of co-innovation and impede the development and functioning of innovation systems. The contribution in the paper is twofold. Firstly, it combines both innovation system functions and systemic problems in an integrated analysis to asses an AIS at a country leve...

Publication date: Available online 12 November 2015 Source:NJAS - Wageningen Journal of Life Sciences Author(s): R. Chenoune, H. Belhouchette, S. Gomez y Paloma, A. Capillon In Sierra Leone, several international organizations are trying to help the government improve the productivity of its rice farms, which currently have the lowest rice yields in West Africa. However, the various programmes attempting to increase rice production, and consequently rice self-sufficient food production, are handicapped by an absence of thorough studies explaining the way rice farmers take the available socio-economic, technical...
