Estimation of growth parameters in Brahman cattle from Mexico
(2023)
The objectives were to evaluate non-linear models (NLM) to define the growth curve of Brahman cattle in Mexico. The database was derived from weight development control, with live weight measurements (150,932 in females and 286,804 in males) taken in the interval from birth to 1095 days of age. Four NLM were evaluated: Brody, Bertalanffy, Gompertz and Logistic. The selection of the NLM with the best adjustment was made based on the Akaike and Bayesian information criteria. Growth parameters were generated: adult ...

Investigating the efficacy of common agricultural practices for the management of fall armyworm (Spodoptera frugiperda (J.E. Smith)) on cereal crops
(2023-07)
In Benin, the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is the most important polyphagous noctuid pest. This study aimed to assess the impact of agricultural practices on the abundance of this pest and determine whether its feeding preference and larval development differ among four cereal types. First, we conducted a descriptive survey of 80 farmers randomly selected for farm visits and oral interviews using a structured questionnaire to ascertain their preferred agricultural practices ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Hotspot 17 der biologischen Vielfalt - Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“
(2023)
Im Rahmen des Projektes „Schaf schafft Landschaft“ wurde von Oktober 2019 bis April 2022 eine Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“ (Hotspot 17) erarbeitet. Bei dieser Hotspotkonzeption wurde ein überregionaler, umsetzungsorientierter Ansatz verfolgt und die gesamte Region des Hotspot 17 in den Blick genommen, um möglichst umfassend die Themen mit besonderer naturschutzfachlicher Relevanz für den Erhalt der Biodiversität zu erkennen und mit ...

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 ...

Development of a new methodology in sensory science to detect the intention-behaviour gap in organic food consumption and investigate the effect of this gap on consumer’s subjective wellbeing
(2020-08)
Aktuelle Umweltherausforderungen wie die globale Erwärmung, der Klimawandel und der Verlust der biologischen Vielfalt und der natürlichen Ressourcen hängen mit dem Verhalten der Menschen zusammen. Nicht nachhaltige Produktion und Konsum erklären die meisten dieser Herausforderungen. Daher interessieren sich immer mehr Verbraucher für Bio-Lebensmittel, um ihr Engagement für ein nachhaltigeres Lebensmittelverhalten zu demonstrieren. Infolgedessen ist der Markt für Bio-Lebensmittel in letzter Zeit gewachsen. Verbraucher ...

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 ...
