Integrated bioenergy and food production
(2015)
Rising global energy needs and limited fossil fuel reserves have led to increased use of renewable energies. In Germany, this has entailed massive exploitation of agricultural biomass for biogas generation, associated with unsustainable farming practices. Organic agriculture not only reduces negative environmental impacts, organic farmers were also prime movers in anaerobic digestion (AD) in Germany. This study’s aim was to identify the structure, development, and characteristics of biogas production associated with ...

Optimization of Processing Technology for Commercial Drying of Bananas (Matooke)
(2014-05-08)
Summary -
Cooking banana is one of the most important crops in Uganda; it is a staple food and source of household income in rural areas. The most common cooking banana is locally called matooke, a Musa sp triploid acuminate genome group (AAA-EAHB). It is perishable and traded in fresh form leading to very high postharvest losses (22-45%). This is attributed to: non-uniform level of harvest maturity, poor handling, bulk transportation and lack of value addition/processing technologies, which are currently the main ...

Climate change and hunger as the challenges in the global food system
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-04-25)
In the last decades, there has been a growing tendency towards international trade and globalisation, particularly leading to a significant increase in flows of agricultural commodities worldwide. From a macroeconomic perspective, the commodity projections are more optimistic than the previous years and the long run tendency shows an increasing demand for feedstock. However, the strong shifts of shocks and fluctuations (in terms of prices and volumes) are a concern to global food security, with the number of hungry ...

Spatio-temporal patterns of herbage availability and livestock movements: A cross-border analysis in the Chinese-Mongolian Altay
(Springer, 2016-07-04)
Due to increasing population and the recent implementation of policies to intensify the use of land and water resources, the transhumant pastoral systems in the Chinese-Mongolian Altay-Dzungarian region are rapidly changing, leading to modifications of herd size, herd composition and spatial distribution of livestock grazing. This may have major consequences for the supply and quality of rangeland biomass. Despite similar topographic settings, the socio-political framework for Chinese and Mongolian pastoralists differs ...

Socio-economic characterisation of date palm (Phoenix dactylifera L.) growers and date value chains in Pakistan
(Biomed Central, 2016-08-02)
Increasing food production to feed its rapidly growing population is a major policy goal of Pakistan. The production of traditional staples such as rice (Oryza sativa L.) and bread wheat (Triticum aestivum L.) has been intensified in many regions, but not in remote, drought-ridden areas. In these arid, marginal environments dates and their by-products are an option to complement staples given their high nutritive value and storability. To fill knowledge gaps about the role of date palm in the household (HH) income ...

Applying Least Absolute Shrinkage Selection Operator and Akaike Information Criterion Analysis to Find the Best Multiple Linear Regression Models between Climate Indices and Components of Cow’s Milk
(MDPI, 2016-07-23)
This study focuses on multiple linear regression models relating six climate indices (temperature humidity THI, environmental stress ESI, equivalent temperature index ETI, heat load HLI, modified HLI (HLI new), and respiratory rate predictor RRP) with three main components of cow’s milk (yield, fat, and protein) for cows in Iran. The least absolute shrinkage selection operator (LASSO) and the Akaike information criterion (AIC) techniques are applied to select the best model for milk predictands with the smallest ...

Enlarging a training set for genomic selction by imputation of un-genotyped animals in populations of varying genetic architecture
(BioMed Central, 2013)
Background: The most common application of imputation is to infer genotypes of a high-density panel of markers on animals that are genotyped for a low-density panel. However, the increase in accuracy of genomic predictions resulting from an increase in the number of markers tends to reach a plateau beyond a certain density. Another application of imputation is to increase the size of the training set with un-genotyped animals. This strategy can be particularly successful when a set of closely related individuals are ...

Assessing the impact of agricultural drought on maize prices in Kenya with the approach of the SPOT-VEGETATION NDVI remote sensing
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2016-12-23)
The high cost of maize in Kenya is basically driven by East African regional commodity demand forces and agricultural drought. The production of maize, which is a common staple food in Kenya, is greatly affected by agricultural drought. However, calculations of drought risk and impact on maize production in Kenya is limited by the scarcity of reliable rainfall data. The objective of this study was to apply a novel hyperspectral remote sensing method to modelling temporal fluctuations of maize production and prices ...

Post-harvest handling practices and associated food losses in sweetpotato and cassava value chains of southern Ethiopia
(2018-02-12)
In dieser Studie wurden die Nachernte-Ketten von Süßkartoffel und Maniok in Südäthiopien untersucht. Schlüsselfaktoren, die für Nahrungsmittelverluste verantwortlich sind, wurden identifiziert und mögliche Verbesserungsmaßnahmen vorgeschlagen.
Es wurden innerhalb der Süßkartoffel-Wertschöpfungskette die landwirtschaftlichen Betriebe und der Einzelhandel mit einem Ausschuss von bis zu 20% bzw. 25% als "hot-spots"

Entwicklung eines Online-Messverfahrens zur Bestimmung des Bodenbedeckungsgrades bei der Stoppelbearbeitung zu Mulchsaatverfahren
(2010-08-13)
Die vorliegende Arbeit ist Teil eines Verbund-Forschungsprojektes mit dem Ziel, eine Präzisions-Bodenbearbeitung in Abhängigkeit von verschiedenen Bodenparametern sowie dem Bodenbedeckungsgrad zu realisieren. Ziel dieses Teilprojektes war die Bereitstellung einer Online-Messung des Bedeckungsgrades, um die Bearbeitungsintensität während der Feldüberfahrt regeln zu können: Ein Kamerasensor vorne am Schlepper ermittelt die Bodenbedeckung und ein Tiefen-Sollwert wird an das Regelsystem eines Gerätes zur teilfächenspezifischen ...
