Telling data: The accountancy record of a Chinese farmer
Publication date: 7 March 2014 Source:NJAS - Wageningen Journal of Life Sciences, Volume 68 Author(s): Yong Zhao , Jan Douwe van der Ploeg This paper presents and analyses the notebook of a Chinese farmer. The notebook contains a wealth of farm accountancy data. The data and the many interrelations contained in them, are used to describe the structure and dynamics of farming in NW China. The availability of former notebooks that played an important role in agrarian history of Europe, turns out to be helpful for the interpretation of this Chinese notebook. The analysis centers on the question whether Chinse agricultur...

Climate Change and Wheat Production in Pakistan: An Autoregressive Distributed Lag Approach
This study aims to look at the impact of climate change on wheat production in Pakistan. The study uses Autoregressive Distributed Lag (ARDL) model to evaluate the impact of global climate change on the production of wheat in Pakistan. The study considers annual data from 1960 to 2009. On the basis of this historical data the study tries to capture the impact of climate change on wheat production up to now. The results of estimation reveal that global climate change doesn’t influence the wheat production in Pakistan. However, on the basis of the results some appropriate adaptative measures are proposed to confront any ad...

Farming with care: the evolution of care farming in the Netherlands
Publication date: 7 March 2014 Source:NJAS - Wageningen Journal of Life Sciences, Volume 68 Author(s): Jan Hassink , Willem Hulsink , John Grin The aim of this paper is to describe and understand the evolution of the care farming sector in one of its pioneering countries, the Netherlands. Care farms combine agricultural production with health and social services. Care farming is a phenomenon that faces specific challenges associated with connecting two different domains. Organizational ecology, social movement theory and the multi-level perspective are helpful concepts in interpreting and contextualizing the develop...

Nitrate leaching and apparent recovery of urine-N in grassland on sandy soils in the Netherlands
The objective of this study was to quantify the effect of artificial urine application at different dates on nitrate leaching in a well drained sandy soil. In three subsequent years, we measured nitrate leaching and apparent urine-nitrogen recovery (ANR) in a field experiment and in two lysimeter experiments over a period of 1 year post urine application. Artificial urine patches with 400kgha−1of urine-N were applied at different times of the grazing seasons. For the field experiment, we compared nitrate leaching measurements with NURP model calculations. In the field experiment, greatest ANR was measured for spring and ...

Africa and the Green Revolution A Global Historical Perspective
This study interprets recent signs of agricultural productivity growth from a long term global historical context, arguing that the combination of present-day developments in information and communication technology, transport infrastructure, demographic growth, urbanization and in macro-economic governance form a fundamental break with African history. This break does not offer any guarantees, but it does raise the probability that Africa will complete a green revolution of its own. (Source: NJAS Wageningen Journal of Life Sciences)

Relationship between chemical composition and in situ rumen degradation characteristics of grass silages in dairy cows
The objectives of this study were to 1) generate a new database on the rumen degradability of dry matter (DM), organic matter (OM), crude protein (CP) and neutral detergent fibre (NDF) of grass silages, 2) compare this new database with the old database used in the DVE/OEB2010 system, and 3) derive regression equations using the new database to investigate the relationships between chemical composition and in situ ruminal degradation characteristics of DM, OM, CP and NDF of the grass silages. Sixty nine grass silages, with a broad range in chemical composition and quality parameters, were selected and incubated using the n...

The non-GM crop regime in the EU: How do Industries deal with this wicked problem?
Publication date: Available online 27 March 2014 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Linde Inghelbrecht , Joost Dessein , Guido Van Huylenbroeck In the European Union (EU), genetically modified (GM) crops are regarded as a socially-sensitive technology. At present, GM crops are rarely cultivated in the EU and non-genetically modified ingredients dominate the EU market. However, most consumers are unaware of the fact that many genetically modified ingredients (GMI) are present in EU supermarkets in spite of this virtual ban on GM. For example, eggs, meat or milk derived from GM-fed animals ar...

Differences in TFP growth among groups of dairy farms in the Netherlands
Publication date: Available online 12 April 2014 Source:NJAS - Wageningen Journal of Life Sciences Author(s): T.H. Keizer , G. Emvalomatis The trend towards fewer and larger farms characterising agriculture in most industrialised countries can be partly attributed to larger farms becoming more productive by exploiting the economies of scale inherent in the production technology they employ. This paper examines whether larger and more intensive dairy farms in the Netherlands have been experiencing faster productivity growth than smaller farms, with the objective of determining which types of farms are more likely to p...

Determination of Molecular and Biochemical Changes in Cotton Plants Mediated by Mealybug
Publication date: Available online 2 June 2014 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Shazia Shafique , Aqeel Ahmad , Sobiya Shafique , Tehmina Anjum , Waheed Akram , Zoobia Bashir Phenococcus solenopsis (cotton mealybug) is a devastating insect pest of many countries of the world including Pakistan. Due to its piercing sucking type feeding behavior, it injures cotton plants mechanically and induces several cytological and physiological changes in the host. These changes have been studied after subjecting healthy plants with mealybug under controlled conditions and it was recorded that meal...

Intercropping sunflower and soybean in intensive farming systems: Evaluating yield advantage and effect on weed and insect assemblages
Publication date: Available online 2 June 2014 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Elba B. de la Fuente , Susana A. Suárez , Adriana E. Lenardis , Santiago L. Poggio Agricultural intensification has encouraged both landscape homogenization and biodiversity decline in agro-ecosystems. Intercropping may over yield sole crops and simultaneously enhance landscape heterogeneity and planned and associated biodiversity in agroecosystems. Thus, we assessed yield advantage in sunflower/soybean intercrops in the Southern Pampas (Argentina). We also expected weed and insect assemblages to differ betw...

Learning experiences that produce environmentally active and informed minds
This study provides evidence of the significant life experiences that have influenced teachers’ attitudes towards the environment and present their teaching practices within environmental education. Three groups of teachers (preschool, primary school and biology), working in preschools and in nine-year long compulsory basic schools in Slovenia completed questionnaires. Findings were generalised against bodies of research discussing significant life experiences and recomendations concerning environmental education improvement. Enjoyment of the outdoors, especially in the childhood, attitudes of parents, life in the countr...
