How do management practices and farm structure impact productive performances of dairy cattle in the province of Pichincha, Ecuador
(2020-11-11)
The combination of "ancestral knowledge" and modern agricultural techniques are increasingly used by Andes farmers, demonstrating its great importance as an ideal alternative to achieve international standards of productivity and sustainability. Pasture management has demonstrated its relevance in terms of milk volume and quality in farms located in the Ecuadorian highlands, showing a wide range of types of forage resource use, in its constant search for better animal yields from the occupancy rate. However, while ...

The Impact of Missing Values on PLS, ML and FIML Model Fit
(2020)
Structural equation modelling has become widespread in the marketing research domain due to the possibility of creating and investigating latent constructs. Today, several estimation methods are available, each with strengths and drawbacks. This study investigates how the established estimation methods of partial-least-squares (PLS), maximum likelihood (ML) and full-information maximum likelihood (FIML) perform with an increasing percentage of missing values (MVs). The research was conducted by investigating an adapted ...

An approach to the use of technology in the cocoa-growing sector: a look from the producer
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-06)
A study was conducted to keep scientific record of the challenges and opportunities of the insertion of a mobile app for cocoa producers in the Colombia region as a prospective tool or strategy for technological transfer and appropriation into that sector. A survey with structured and semi-structured questions that pertained to cocoa producer men and women was conducted. The questions were related to the general conditions of their labour activities and were discriminant in the following categories: cocoa-grower ...

Optimisation of the seedball technology for sorghum production under nutrient limitations
(2021-04-13)
The seedball technology is a simple and affordable seed-pelleting technique that uses locally available materials such as sand, loam, wood ash and seeds to enhance early crop establishment. It has been shown to be effective for pearl millet (Pennisetum glaucum) subsistence production in Sahelian environments. The objective of this study was to optimise the seedball technology for sorghum (Sorghum bicolor (L.) Moench) under greenhouse conditions. Series of pot experiments were conducted in order to identify optimal ...

Application of check-all-that-apply (CATA) in sensory profile assessment of arabica dark roast and black pepper mixed coffee
(2021-11-29)
Black pepper coffee is one of the developing innovations in Bangka Belitung Province, Indonesia. This study aimed to assess black pepper coffee's sensory profile using the CATA (check-all-that-apply) rapid analysis method and find the formula and brewing technique most consumers liked. The study consisted of two stages: determining the sensory attributes of black pepper coffee and taking sensory data from coffee consumers with coffee and black pepper powder ratios (98:2; 96:4; and 94:6) and brewing methods (cold brew, ...

Agricultural risk assessment to enhance the food systems of the Mbororo minority community in the Northwest region of Cameroon
(2021-10-29)
Increasing population pressure, coupled with the effects of climate change manifested by longer dry seasons, wildfires, and conflicts, threatens the food systems of minority communities. In the case of the Mbororo minority community of Northwest Region of Cameroon, these threats are exacerbated by already existing problems of marginalisation. This study assesses agricultural risks in the global context of food distribution and gross domestic product that also poses a specific threat to the food system of the Mbororo ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

Significado y efectos de sentido. El gérondif francés en el contexto románico
(2021)
En las lenguas románicas una función central de los gerundios consiste en crear vínculos o junciones (Raible 1992) entre acciones diversas en el marco oracional. El concepto de junción implica que dos acciones –la actividad expresada por el gerundio y la actividad de la oración matriz– se agrupan para formar una unidad estructurada. El punto de partida de nuestro estudio es el análisis del gérondif en francés, cuyo perfil semántico-pragmático se elabora en primer lugar y constituye la base de un estudio contrastivo ...

Science–Policy Interfaces Related to Biodiversity and Nature Conservation: The Case of Natural Capital Germany—TEEB-DE
(2020-05-03)
Responding to the UN programme “The Economics of Ecosystems and Biodiversity” (TEEB), TEEB-DE (2012–2018) was a science–policy interface (SPI) set up in Germany with the objective of mobilising scientific expertise for a better consideration of biodiversity and ecosystem services in political and corporate decision-making. The aim of this paper is to contribute to an assessment of TEEB-DE by analysing its objectives, structure, processes and outputs. The analysis is guided by a theoretical framework that takes ...

Determinants of Willingness to Pay (WTP) for organic fertiliser: a case of smallholder potato farmers in KwaZulu-Natal, South Africa
(2021-12-01)
The South African smallholder sector is characterised by relatively low productivity due to persistent deterioration in soil fertility owing to declining organic matter and other essential soil nutrients. Consequently, adoption of sustainable agricultural inputs like organic fertiliser is essential. Although there is sufficient advocacy in the adoption of organic fertiliser, the economic linkage between farmers' socioeconomic factors and willingness to pay (WTP) remains under-explored. This study investigated the ...
